< Back Talensi traditional houses in Ghana Talensi traditional houses in Ghana are centered on the design and construction of homesteads, promoting their indigenous cultural identity and demonstrating the value of social ties. The construction process involves men constructing and roofing structures, with women covering them. The Talensi community combines innovation, local knowledge, and resources to create low-cost, sustainable communities. The standardized construction schedule ensures transparency and reliability, promoting sustainability and reusability of traditional materials. The traditional building of Talensi is principally centered on the design and construction of homesteads. The architectural circular form of these traditional buildings, its homogenous layout, choice of construction materials, and process promotes their indigenous cultural identity, stands as an embodiment of the value of social ties, represents a substantial projection of hierarchical relations that make up a family or clan. Talensi is an area in the Upper East region of Ghana in West Africa, culturally and administratively termed Talensis. House Building among Talensi is guided by a solid sense of kinship, characterized by a cooperative effort by the clan to which a person belongs. Tengzug village, Nothern Ghana photo by imb.org Traditionally, the homestead is identified as a Talensi man’s focus, source of interests, prime initiatives, deepest emotional connections, values, shelter, and esteem of life. Talensi’s view on house construction is that men put up structures and roof them while women cover the structures for habitation, but the contribution of women is not counted, though the entire construction process involves members of varied ages, social standing, skills, and genders. The fusion of innovation, local knowledge, and resources promotes low-cost and sustainable communities tailored to their specifications. The traditional houses of the Talensi are circular with flat roofs although in recent years there has been the introduction of rectangular forms. The buildings are constructed with mud. Wall construction usually includes hand-molding kneaded laterite into standard spherical sizes and using the balls to construct the wall layer by layer. Finishing also involves a standardized process of plastering the wall surfaces with a mixture of mud, cow dung, and juice from boiled empty locust bean tree pods. The juice acts as a stabilizer, hardener, and waterproofing. As a standard schedule, traditional Talensi construction normally happens in the dry season between December and April. This period is without rainfall and the entire construction process, from site preparation to wall and floor finishing, is planned in this period. The need to standardize the construction schedule within this period is further strengthened by the fact that most traditional construction participants are farmers and would be engaged in farming in the rainy season. The standardized scheduling in the dry season is transparent and understood by all participants, thereby enhancing the reliability of the commitment of the entire team to planned activities for projects. This tends to stabilize the flow of construction activities within the planned duration. Sustainability through the indigenous building culture of Talensi is environmentally friendly associated with less generation of waste. This fundamentally stems from the recyclability and reusability of traditional materials. Another dimension focuses on the ability of the traditional building materials to merge back into the natural environment when they are not in use. Previous Next

< Back Learning from green African building Caroline Geffriaud, Goethe-Institut Sénégal The «Learning from green African building» project was launched by the Goethe-Institut Senegal in 2021 with the aim of exploring the richness of sustainable construction in sub-Saharan Africa and creating a network of engaged actors and institutions. The project is divided into two parts: One part is the creation of activities enabling the development and animation of a network of stakeholders and interested parties in the development of sustainable architecture on the continent. The second part is a web platform organized into three sections. The first is an interactive and participatory map that lists the various initiatives on the continent, from vernacular heritage to contemporary buildings, including the involved actors, research projects, resources, and more. The second section is a series of videos produced by the Goethe-Institut, showcasing particularly interesting projects and actors across the continent. The final aspect is a collection of essays written by engaged personalities that offer a definition of sustainable architecture in sub-Saharan Africa today. The African continent is rich in diversity, creativity, and architectural wealth, yet it is underrepresented and under-referenced. This project aims to be a source of information, inspiration, and connection for anyone interested, both on the continent and beyond. The website is accessible at: https://lfgab.com/ Sustainable architecture in Africa relies on frugal, low-tech solutions using local materials to reduce carbon emissions It is now a well-established fact that the construction sector, along with transportation, is one of the most polluting industries in the world. By itself, it accounts for 37% of global greenhouse gas emissions. This staggering percentage also indicates a significant margin for reduction that can be explored. This reduction is particularly achieved through the development of sustainable architecture, meaning architecture that is functional, comfortable, resilient, resource-efficient, and environmentally friendly in the broadest sense. The African continent is experiencing a boom, with a population growth rate of around 5% and the prospect of reaching 50% urbanization by 2030. These indicators are logically accompanied by a construction boom, involving the widespread adoption of foreign architectural models and the massive use of concrete, already the most consumed material in the world and responsible for 4 to 8% of global greenhouse gas emissions. Champ de typha Sénégal - Seydina Ousmane Boye - 2021 While in Europe, active «high-tech» techniques have long been favored to limit the environmental impact of buildings, this approach now seems unreasonable. With the acceleration of the climate crisis and the depletion of fossil fuels, voices are being raised around the world advocating for degrowth. Fortunately, in all climates, there are many examples of the «low-tech» approach, which limits the need for resources and maintenance and implements passive, sustainable, and stable systems. In Africa, due to the technological and energy context, frugality has always been a preferred approach when it comes to sustainable architecture. In a world with limited resources, innovation no longer lies in the race for new technologies but in the reinvention, reinterpretation, combination, and fusion of traditional techniques derived from local cultures, climates, and materials. The use of local resources is one of the keys to reducing the carbon emissions of the construction sector. Reducing the distance traveled by materials, creating local skilled jobs, and limiting the processing of products—these actions all contribute to reducing the energy used in building construction. Additionally, these local resources are often bio- or geo-sourced materials with a high carbon storage capacity, which positively impacts the overall environmental balance of buildings. The Learning from green African building platform highlights sustainable architecture in sub-Saharan Africa, connecting stakeholders through mapped resources and videos The climatic and social conditions, as well as access to resources, being unique, the sustainable approach in sub-Saharan Africa is particularly interesting and inspiring. However, today, the data related to this approach is often not easily accessible to the public. To highlight sustainable construction initiatives and bring together a network of stakeholders engaged in eco-friendly building practices, the Goethe-Institut Senegal has created a web platform that provides access to the wide array of resources on sustainable architecture in sub-Saharan Africa. Carte interractive Learning from green African building - Goethe-Institut - 2024 The platform is presented as a regional map, allowing users to locate the data within its geographical context. Resources are displayed as «points» with different shapes or colors depending on their association with the following themes: Vernacular heritage, Contemporary buildings committed to sustainable development, Renovated buildings, Available natural resources and material experimentation, Private and public actors involved in creating a sustainable construction sector, Places of education and dissemination of sustainable architectural and urban thought, Theoretical or practical research projects and publications, and Occasional events or initiatives. Navigation sur la carte - Goethe-Institut Sénégal - 2021 The map background emphasizes climatic data and available resources, rather than strictly administrative boundaries. This way, the territory is viewed through the lens of natural context, rather than administrative divisions, encouraging technology exchanges between practices operating in similar climates. In certain countries, particularly in Cameroon, Burkina Faso, Mali, Ghana, Angola, South Africa, Rwanda, and, of course, Senegal, video teams were engaged to meet with stakeholders and showcase the richness and diversity of sustainable approaches on the continent. Thanks to this effort, around fifteen videos have already been uploaded, with more in preparation. Additionally, with the aim of offering a body of theoretical reflections in dialogue with the mapped data and videos, the platform features original essays written by key figures on the continent, focused on defining sustainable architecture in Africa today. Exhibitions, roundtables, and presentations across Africa, to promote sustainable architecture through public engagement and local collaboration Since its inception, the project has been the focus of numerous public events, notably the «Learning from Green African Building» exhibition in December 2022, Dakar (Senegal), a roundtable at WITS University in Johannesburg (South Africa), March 2023, and the Learning from green African building Africa Tour inFebruary 2024 where the project was presented at four public events in Ouagadougou (Burkina Faso), Lagos (Nigeria), Accra (Ghana), and Nairobi (Kenya). These events included numerous conferences and debates led by local stakeholders, showcasing the platform, the traveling exhibition, and engaging the public in open discussions. Research is ongoing and is regularly published on the site. The map is participatory, allowing the public to propose new resources to expand the content while ensuring local relevance. Lancement du site projet - Goethe-Institut Sénégal - 2021 Echanges avec le public Accra - Willie Schuman - 2024 Promote sustainable architecture by showcasing local resources and overcoming cultural resistance to eco-friendly building practices Architecture is a reflection of the cultural and environmental context from which it emerges. The Goethe-Institut Senegal is taking advantage of the construction of its future institute in Dakar, designed by Pritzker Prize-winning architect Francis Kéré, to highlight this theme in its cultural program. Rather than importing knowledge, typologies, and materials, how can we make the best use of local resources and knowledge to develop architecture that is adapted to the climate and the expectations of the communities involved? The obstacles limiting the democratization of sustainable construction are no longer technical. The knowledge exists, the tests have been conducted, and in some countries, the regulatory context is evolving in favor of using eco-sourced materials. Today, the resistance is generally cultural, as natural and traditional materials are often seen as outdated and synonymous with poverty, while concrete and glass are associated with wealth, modernity, and the future. The project’s ambition is to show stakeholders, decision-makers, and the general public that an appealing and contemporary ecological alternative is possible in the building sector. LFGAB highlights a wide range of alternative proposals while helping to increase the visibility of the actors, research, and institutions involved. Previous Next

< Back Faire la ville ensemble : co-construire la ville africaine par l'apprentissage Stéphanie Wattrelos Rutily, Insaf Ben Othmane La tendance mondiale à l'urbanisation s'accélère, avec plus de la moitié de la population mondiale vivant en ville, une proportion qui devrait atteindre 70 % d'ici 2050. Cependant, 90 % de cette croissance se produit en Asie et en Afrique, avec 75 % concentrée dans les villes intermédiaires de moins d'un million d'habitants. Les gouvernements africains sont confrontés à d'énormes défis pour améliorer les conditions de vie et répondre aux besoins des nouveaux citadins. L'urbanisme participatif représente un changement de paradigme qui appelle à des arrangements coopératifs où les habitants et les acteurs de la ville participent au processus de planification, de conception et de gestion. Le Campus AFD, Oecumene Spaces For Dignity et Africa Innovation Network ont co-construit « Faire La Ville Ensemble » pour soutenir les acteurs de la ville dans la prise de conscience des changements de paradigme nécessaires. La structure pédagogique numérique alterne entre apprentissage en ligne et temps collaboratifs dans un atelier numérique, fondée sur des principes pédagogiques innovants. Nous vivons dans un monde en rupture, où tout change, tout s'accélère, tout devient plus complexe, plus fragile et incertain. La planète s'urbanise à un rythme sans précédent. Déjà, plus de la moitié de la population mondiale vit en ville ; cette proportion atteindra 70 % d'ici 2050. Toutefois, bien que cette tendance soit mondiale, elle n'est pas uniforme : 90 % de la croissance urbaine mondiale se produit en Asie et en Afrique, avec des caractéristiques variées d'un pays à l'autre en termes de vitesse, d'échelle, de structure du tissu urbain et de couverture territoriale ; la croissance urbaine se déroule dans des mégapoles, mais 75 % de cette croissance se produit et continuera de se produire dans les villes intermédiaires de moins d'un million d'habitants. Les gouvernements africains, tant nationaux que locaux, sont confrontés à d'immenses défis pour améliorer les conditions de vie de leurs habitants et répondre aux besoins des nouveaux citadins. L'ampleur, la force et la vitesse de ces changements nous obligent à agir rapidement, à réinventer nos façons de penser et de vivre dans le monde, et surtout à replacer les habitants et les utilisateurs au cœur de la construction des villes et des territoires. « L'urbanisme participatif est un paradigme de planification qui appelle à des arrangements coopératifs dans lesquels les habitants et les acteurs de la ville sont impliqués dans le processus de planification, de conception et de gestion. Il promeut le dialogue ouvert et la collaboration fructueuse entre les parties prenantes : habitants, utilisateurs, experts, décideurs et investisseurs, permettant de renforcer la cohésion sociale et une meilleure gestion des ressources avec un engagement toujours plus grand des communautés, des institutions locales et des acteurs locaux. Cependant, l'urbanisme participatif n'est pas intuitif. Il nécessite un fort engagement des maîtres d'ouvrage et, par conséquent, des élus locaux ainsi que la participation d'une vaste gamme d'acteurs prêts à s'investir. Il requiert un investissement important en temps et en ressources, une méthodologie structurée et des efforts ciblés pour assurer le succès. Qui dit urbanisme participatif dit participation. De nouvelles compétences doivent être acquises pour mobiliser et fédérer les acteurs locaux, collaborer et co-construire. » Insaf Ben Othmane Hamrouni, Fondatrice et Directrice exécutive, Œcumene Spaces For Dignity. La construction de la ville, en Afrique comme dans le monde, ne peut plus se faire sans les habitants, les utilisateurs, les acteurs économiques, les associations, les experts et les opérateurs. Cela doit être présent à toutes les étapes du projet (de sa conception à sa mise en œuvre). Ce changement de paradigme dans la manière de penser l'urbanisme et cette reconfiguration des rôles impliquent de nouveaux « modes de faire » : « faire avec » et, surtout, « faire ensemble ». Le continent africain bénéficie de certains atouts, tels que : La puissance de l'innovation africaine combinant à la fois l'esprit du jugaad (faire mieux ou aussi bien avec moins de ressources) et le leapfrogging (capacité à faire un bond qualitatif) ; Une culture du collectif et de la fabrication informelle de la ville (une culture de l'apprentissage communautaire) ; L'émergence des communs urbains, qui prennent la forme de « lieux, publics ou privés, partagés par les habitants qui développent des usages pluriels, impliquant ainsi une multitude d'acteurs différents dans une gouvernance ouverte et mobilisant les ressources variées du territoire, matérielles et immatérielles, pour des usages destinés à différents cercles d'utilisateurs » (Françoise et al., 2022). Ces communs urbains se concrétisent de manière plus tangible par le développement de tiers-lieux culturels, de terrains de sport, de jardins partagés, de Fab labs, d'espaces de marché et de communautés d'apprentissage. En Afrique, des initiatives d'urbanisme participatif ont émergé dans le processus de fabrication du tissu urbain et prennent des formes multiples, telles que l'urbanisme tactique, l'urbanisme éphémère, l'urbanisme temporaire, l'urbanisme transitoire, etc. Véritable levier de transformation des territoires par la co-construction, le partage, la participation et l'innovation, l'urbanisme participatif offre de nombreuses opportunités pour construire des territoires plus inclusifs, résilients et durables, répondant aux besoins de leurs habitants. Pour Luc Gnacadja, la gestion et la gouvernance urbaine doivent se hisser à la hauteur des défis. Le premier facteur requis est le leadership et la qualité managériale des acteurs clés de la gouvernance publique. « Nous ne sommes pas équipés pour sortir de nos schémas mentaux et inventer de nouvelles manières de faire ; nous devons collectivement apprendre à libérer nos imaginaires et à nous affranchir de nos préjugés, à penser systématiquement et à connecter plutôt que séparer. Il ne s'agit pas d'éclipser le savoir-faire technique, mais de renforcer la capacité à identifier, mobiliser et synergiser les initiatives sur le terrain pour activer des collaborations qui mettent en valeur l'intelligence collective et partagent la connaissance, la créativité et la co-construction de solutions propres à chaque territoire. Et cela doit être appris, vécu et expérimenté plutôt que décrété. » Stéphanie Wattrelos Rutily, Urbaniste, chargée de projets pédagogiques, Campus AFD. La ville africaine durable doit être plus inclusive, libérant la créativité de chacun pour construire des solutions durables. Pour relever le défi de la ville pour tous et soutenir les acteurs de la ville dans la sensibilisation aux changements de paradigme nécessaires, le Campus AFD, Oecumene Spaces For Dignity et Africa Innovation Network ont co-construit, avec et pour ces acteurs, « Faire La Ville Ensemble » un nouveau parcours d'apprentissage immersif et collaboratif. Ses objectifs : comprendre les dynamiques complexes à l'œuvre dans les territoires urbains ; identifier les notions de participation et co-définir ensemble les concepts clés pour une participation ouverte et partagée en Afrique ; sensibiliser et initier les acteurs de la ville en Afrique aux approches et outils pour co-construire des projets urbains en s'appuyant sur l'intelligence collective et la créativité. Cette formation vise à transformer les postures et à accompagner le changement pour passer du rôle traditionnel de chef de projet à celui de facilitateur au sein de son territoire. « Ce que je retiens de mon parcours sur “Faire la ville ensemble”, ce sont ces moments intenses qui ponctuent les différentes phases de mise en œuvre de la participation comme outil essentiel à la fabrication de la ville. Cet exercice complexe et instructif nous a permis, en tant que participants, de faire face aux défis de nos villes, notamment en Afrique, où l'anarchie, la précarité et l'absence de planification stratégique en constituent le trait central. Mais à mesure que nous apprenions ces méthodes de participation, nous avons réalisé qu'il est possible de rêver de villes africaines inclusives et durables qui se construisent différemment, avec de nouvelles approches impliquant les différents acteurs dans la création d'une vision partagée de leur ville. Cela permet aux autres parties prenantes de planifier ensemble et de travailler vers un objectif commun. Ces méthodes bénéficient à l'Agence d'urbanisme du Grand Tunis, qui intervient principalement pour assister les autorités locales dans l'élaboration de leurs outils d'urbanisme, constituant une opportunité de mettre ces approches en pratique. » Jihene Ghiloufi Dahmeni, Ingénieur, Directrice de la gestion de l'information urbaine, Tunisie. La structure pédagogique numérique « Faire la Ville Ensemble », co-construite avec les acteurs locaux, alternera apprentissage en ligne et temps collaboratifs dans un atelier numérique, en s'appuyant sur des principes pédagogiques innovants, à savoir : Conçue comme un commun numérique, la plateforme « Faire la Ville Ensemble » propose du contenu éducatif dynamique et interactif (expériences de terrain, vidéos, infographies, boîtes à outils, quiz...) à découvrir à son propre rythme et en autonomie ; Et pour explorer, inventer, se mettre à la place de… et apprendre par le jeu, l'intelligence collective et la créativité, des ateliers numériques collaboratifs ponctuent tout le parcours pour ceux qui disposent de plus de temps. Plus qu'une simple formation, « Faire la Ville Ensemble » est une véritable expérience d'apprentissage qui s'appuie sur l'innovation, l'intelligence collective et la puissance du partage d'expériences. C'est avant tout une communauté d'acteurs de la ville engagés dans la volonté de replacer l'humain au cœur de la construction de la ville. Previous Next

< Back Leveraging digital technologies for mapping deprived areas in eThekwini, South Africa Dr. Sophie Naue, Michael Hathorn Informal settlements are home to one-quarter of the world’s urban population and the number is expected to increase in the coming years. Overall, around 1 billion urban drawlers live in settlements that are often characterized by poor housing conditions and unsecure tenure, located at the urban periphery with limited access to basic services such as clean water, electricity, and sanitation. The improvement of living conditions for these inhabitants remains a pressing global challenge. However, this massive urban growth often leads to outdated records and inaccurate data on deprived areas, which hampers public entities in sustainable planning and responses to resident needs. This raises the question: How can digital technologies help to better understand informal settlements and provide cities with spatial data to support evidence-based planning processes? Considering these challenges, UNITAC Hamburg developed BEAM (Building & Establishment Automated Mapper), a machine learning tool for mapping informal structures using aerial imagery that was piloted in collaboration with the Human Settlement Unit from eThekwini Municipality in South Africa. This project article focuses on the challenges of mapping informal settlements, considering the piloting and development of the BEAM tool in the case of eThekwini. Accurate data is crucial for upgrading informal settlements and enhancing resilience eThekwini municipality has the largest number of informal settlements in South Africa with over 587 settlements, accommodating over 314,000 households. This accounts for more than a quarter of the entire city’s population. To address this issue and strengthen community resilience the city has embraced an ambitious informal settlement upgrading programme including basic urban service delivery, housing projects and land management mechanisms. But developing a pipeline of urban upgrading and basic service delivery projects necessitates up-to-date information on the number and location of informal structures as well as environmental constraints that could prevent provision of urban basic services and affordable housing. While eThekwini Municipality is engaged in spatial data collection efforts, data on its deprived areas remains scarce. Aerial view of informal settlements in eThekwini municipality, South Africa Mapping deprived areas presents a significant challenge due to their unplanned and dynamic nature Traditionally, spatial data collection relies on survey-based approaches and census data, which continue to be both costly and time-consuming with long gaps between censuses (typically 5 – 10 years) and additional time before the information is available. Given the rapid development of informal settlements, data collected using such methods may already be obsolete when released to the user (Mahabir et al., 2018, p.4). Considering the above, aerial photography or satellite imagery can provide a detailed view of the physical structure of settlements by facilitating the extraction of building footprints. Although these methods do not capture the intricacies of informal settlements, to say nothing of the characteristics of the people living there, they provide a fast and low-cost picture of the morphology and structure of these areas. In comparison, traditional mapping remains time-consuming and is a complex process, requiring a nuanced understanding of the political, social, and economic dynamics that shape these neighborhoods. In eThekwini, data has been collected by 15 on-the ground land monitors servicing 587 settlements (eThekwini HSU, 2021). This process cannot keep track of the fast changes in the built environment. The workflow has limited the city’s capacity to respond to residents’ needs. Another source of information is remotely-sensed images. These include satellite images, lidar data, and 2,500 km2 of annually captured aerial photography, which are manually analyzed and digitalized by the GIS Cooperation of eThekwini (eThekwini HSU, 2021). The size of the areas that need coverage and the rate of change of informal settlements mean that the established processes struggle to capture and maintain data in a robust and timely fashion. These challenges align with UN-Habitat’s recent global study of smart city governance practices (UN-Habitat, 2022), which revealed that less than half of African cities effectively combine manual data with automated data and data from large-scale databases to inform decision making. Building & Establishment Automated Mapper: Using Machine Learning to map informal settlements In recent years digital technologies like remote sensing, lidar data, and deep learning have become helpful tools to improve mapping processes of informal settlements. However, developing remote sensing technologies is resource intensive and requires specialized training to operate, which can be a major obstacle for municipalities such as eThekwini. To this end UNITAC Hamburg collaborated with the Human Settlement Unit in eThekwini to develop BEAM (Building & Establishment Automated Mapper). BEAM is a mapping tool for city planners that uses ML to radically accelerate the spatial recognition of informal settlements based on aerial imagery. The tool was developed as an easy-to-use application that allows the user to quickly detect and visualize urban footprints in a specific area by simply uploading aerial images of a given location. Users have a choice of using one of two trained models (U-Net or HRNet), which offer tradeoffs in speed and performance. Images showing the labeling and training process 1, UNITAC 2024 The algorithm is trained to identify and to mark all pixels on an aerial image that the model considers as part of a building. These pixels are converted to georeferenced polygons, which represent building footprints. Those layers can be used to calculate the density of informal settlements in a very easy and quick manner or to identify changes over time, including the expansion, densification, and establishment of new settlements. Reasons for low identification accuracies of informal settlements are attributed to their rather different morphological characteristics (e.g., higher roof coverage densities, more organic patterns, and small building sizes) compared to formal built-up areas. Due to the heterogeneous characteristics of informal settlement the team had to face various challenges in training the BEAM algorithm. In particular, the model’s performance suffered when being run on building typologies that were not represented in the training set, and on imagery that was not from the same year. To address these issues, a more diverse training dataset was created, and the training pipeline was adapted to make the models more robust on out-of-sample imagery. Outputs from an early (prototype) model., UNITAC 2024 Maintain records of informal settlements’ location, extent, and changes, using BEAM’s outputs for tracking and urban planning The BEAM tool was co-designed with the Human Settlement Unit, to correspond to their needs and handed over to the city after development. To ensure direct access and advocate local ownership UNITAC also provided a manual, with a step-by-step guidance on how to install and use the tool and conducted serval tech sessions for knowledge and skills transfer, required for the effective use and integration of the tool into the existing workstreams of the municipality of eThekwini. Currently BEAM is being tested by the eThekwini GIS Cop. who has provided feedback and recommendations for improvement. There are several benefits of using algorithms like BEAM for mapping informal settlements including: Accuracy: ML algorithms can accurately map informal settlements using aerial or satellite imagery, providing a precise understanding of their location, size, and extent. Efficiency: Using ML accelerates the mapping process, saving time and resources compared to traditional methods like surveys or manual digitalization, while still delivering reliable data. Scalability: ML algorithms can be trained to analyze large data sets, useful for monitoring changes over time and identifying areas needing infrastructure development or vulnerable to environmental impacts. Challenges associated with mapping informal settlements using ML models include: Data Availability: High-quality data is needed to train ML algorithms effectively. Limited access to aerial or satellite imagery can hinder this process. Complexity: Informal settlements are diverse, with varying building materials, construction methods, and patterns, making it difficult to develop accurate ML algorithms. Ethics: ML use raises ethical concerns about privacy, surveillance, and consent. Maintenance: Continuous updates and training of algorithms are necessary to maintain accuracy and relevance, addressing the critical issues of scale and data access. Despite the challenges above, today BEAM detects urban footprints on aerial photography achieving an accuracy (Dice coefficient/F1 score) of 91% on an out-of-sample test set. It processes one image in 70 to 90 seconds. With this performance the BEAM tool allows the city to have up-to-date records of the location and extent of its informal settlements as well as to keep track of changes in the built-up area or density over time and leverage the tool output for planning. Using BEAM eThekwini can reduce the time it takes to map all informal settlements of the city from an estimated 1,320 working days to 72 hours. The tool does the work that otherwise would have taken months and a whole project team. The tool allows the municipality to automate and accelerate mapping processes and achieve more efficient and evidence-based planning processes by understanding the dynamics of Informal settlements. Model outputs (left) vs ground truths (right), UNITAC 2024 Machine Learning tools enhance urban planning but require ethical use, privacy protection, and community benefits Mapping deprived areas using ML tools has the potential to provide a more accurate and efficient method of identifying urban growth and density. This can help cities and other policymakers to better understand the dynamics of those areas and inform decision-making processes related to urban planning, housing, and infrastructure development. To manage and understand the massive urban growth, related constraints and opportunities in African cities, digital mapping tools, such as BEAM are critical. Accurate and up-to-date data is essential to the improvement of public service delivery and enhanced government workflows. Effective urban mapping workflows are vital to streamlining urban service delivery and enabling data-based policies for urban governance and management. Overall, while ML technologies can provide valuable insights of informal settlements there are several challenges and also risks associated with its use. Addressing these will be crucial to ensure that the use of such tools is not only effective but also ethical. Therefore, efforts to map informal settlements must be sensitive to addressing the needs and rights of residents, while also providing decision-makers with information they need to make informed policy decisions. The success of such endeavors relies on ensuring that communities and civil society do benefit from these tools. To minimize potential risks, it is crucial to establish appropriate data policies that protect privacy and ensure responsible data use. By prioritizing the well-being of residents and implementing the right data policies as well as participatory approaches, we can effectively harness the potential of mapping technologies to create positive change.

< Back Education in architecture, planning and design in Africa: Challenges and vision for more sustainable and resilient African cities Architectural education in Africa needs a shift. This involves integrating local social, cultural, and environmental considerations. The current Western-centric curricula are critiqued and a more holistic approach is advocated. Interviews with academics and researchers highlight the gap between traditional grid-pattern city planning and the actual needs of African communities. The importance of community engagement and understanding local contexts is stressed. Students are encouraged to explore African architectural heritage, engage with diverse perspectives, and adopt bottom-up approaches. This will help graduates build sustainable and resilient cities that address the unique challenges and opportunities in African urban environments. MARK OLWENY, Architect, Educator, Senior Lecturer in Architecture, School of Architecture and the Built Environment, University of Lincoln, Research Associate Professor, Faculty of the Built Environment, Uganda Martyrs University. Experienced Senior Architect with a demonstrated history of working in developing countries. Skilled in Environmental Design, Sustainable Architecture, Urban Design and Architectural Education. Strong administrator, Doctorate in Philosophy (PhD) focused in Architecture from Cardiff University / Prifysgol Caerdydd. I believe a new direction for architecture and planning education should begin with a more holistic approach Unfortunately, architectural and planning curricula on the continent are still largely based on the western approach. Thus, much of what is taught and what is considered important in the curricula comes from outside rather than within the continent. Moreover, if you look at some of the old schools that came into being around independence in Kenya, Ghana, Nigeria, and more recently in Zimbabwe, etc., their objectives have been to train people to produce buildings that celebrate the aspirations of these independent states. The result is seen in the architecture and layout of our cities where what is perceived to be a ‘good city’ is one that is planned in a grid pattern, with streets primarily for cars, which has absolutely nothing to do with how people actually use space in the African context. Consider the fact that most people don’t drive. For them, to get from A to B the distance should be as short as possible. I don’t need space for four or at times six cars, I need comfortable space for people to walk. So if we start thinking about people first, the way our spaces are designed and laid out will be very different. But a lot of the current approaches to architecture and planning are car oriented despite only 5% of people using cities actually drives. So once we adopt this idea of planning from a physical entity, we automatically exclude people. But when you look at it from a people’s perspective, one of the things you don’t do in planning is produce a map. In South Sudan, there have been a series of proposals for Juba that are in the shape of animals. Although these may seem appropriate on a plan, this ignores the reality that these are not visible or apparent for the users as people experience urban spaces when they are within them, and not from the sky. Some schools, and mainly the newer ones, manage to break away from this paradigm. But most of them still remain in this way of thinking where man is put aside in architectural and urban designs. This is also the case in private schools that do not find it lucrative to detach themselves from the classical teaching methods. Personally, I believe a new direction for architecture and planning education should begin with a more holistic approach, one that compels students to appreciate specific social, cultural and environmental issues. Here education could take a leaf from landscape architecture education. Landscape architecture education and the profession engage with social and cultural issues in ways that architecture and planning do not. Landscape architecture asks questions, like, what is the meaning of a place? Why do people do it this way? How can we make it work? Rather than saying, well, this looks horrible, let’s just tear it down or start from scratch. Juba city Southern Sudan, Photo source: Google earth “We need to adapt the teaching to the local context. It may not produce the high architecture that we see in the world, but it will meet the local needs..” I will focus on the case of Anglophone Africa, on architectural education specifically and address three aspects: how were the schools of architecture created, who teaches in them and what were their objectives? There are parallels with planning, which I will include when I can. As far as their creation is concerned, by far the majority of architecture schools came into existence just after independence (outside South Africa, these are Ahmadu Bello University, University of Nairobi and University of Khartoum). While the initial goal was to provide skilled labour to replace expatriate staff, the desire by the newly independent states to showcase their aspirations, and demonstrate their position internationally, it was not long before educational endeavours were steered toward fulfilling these objectives, geared toward national prestige through iconic - an ideological imperative. Now, for the teachers in these schools. Initially, it was necessary to rely on foreign staff, for a number of reasons, but primarily the schools were following an international curriculum that needed staff that could deliver it satisfactorily. These instructors largely came from Western Europe (generally former colonisers countries), as well as the Soviet Union, the United States and to a lesser extent India). . While this has served to allow the development of divergent currents of thought, there has been little in-depth interrogation of the appropriateness of these curricula and pedagogical approaches. The most obvious example I can cite here are many history and theory courses, which still rely heavily on a chronological approach heavily biased toward European architectural and planning endeavours. You have to ask yourself, is the knowledge content, and approaches to architecture and urbanism we teach fit for-purpose? and in many cases the answer is no. There is a need for us to scrutinise what we teach and how we teach it. What exactly are we doing? What is the purpose of architecture and planning education now? Do we want to produce replicas of cities and buildings in Europe and North America? Or do we want to help improve the conditions of people?The situation on the ground and the needs are completely different. We need to adapt the teaching to the local context. It may not produce the ‘high’ architecture, but it will meet the local needs. Uganda for example is a very hilly country. But many plans (both planning and architectural) ignore this fact. Why does this happen? In some aspects the training is not context specific; it seems to reinforce the notion that the site (and people) should adapt to suit the designs, and not the other way around. So we need to do better than that and think, how do we compel the next generation of urban planners and architects to be cognisant of and respond to the local situation, understanding that and work with it as a basis for developing appropriate spaces that work for people. When you look at, for example, the most common building typology in Uganda today, it is the same as that designed during colonial times for single men. These «boys’ quarters» because at that time in many parts of Africa, there was a need for workers, usually young men who came to town to work, and were granted temporary residency. To prevent them bringing their families, they were provided with minimal accommodation with small rooms that barely accommodated one person, with shared toilet facilities, and no kitchens... Now more than 60 years after independence, we still build the same way. So if after all these years and all the architects and urban planners trained, why is it that there has not been any change? I believe this is because as architects and planners we have failed to impact on the general population, and continue to train subsequent generations to ignore the needs of the majority. Uganda-Development Photo source: Wikimedio commons “Students are unfortunately taught to prepare to make the next tallest building, rather than getting them to understand the sense of the place…” The way architecture and urban planning training is delivered on the continent has indeed an impact on African cities. On the positive side it can create functional spaces where people have decent environments to live, work and recreate. But on the negative side, I think things are often done out of context. Take housing for example, this is often developed and planned in isolation of socio-economic realities, an approach that reduces the question of ‘low-income’ housing to the provision of the proverbial four walls and a roof. Consequently, we often see such housing developed far away from the centre of cities. These are a distance away from economic and employment opportunities - the reason people migrated to the cities’ areas in the first place. Oddly enough, this was a problem that was seen in the US, UK and Australia during the 1960s, so why are we building the same mistakes in 2020? We have to rethink our approach, taking note that some of what is still taught is obsolete, and in many cases was not actually based on the realities experienced within the context within which it is taught. Back to the housing question, the lack of housing and the burgeoning slums, squatter and informal settlements close to the city centres are a result of a larger question. It comes to human dignity and the value of humanity. By paying a salary that is barely enough to live on, workers are compelled to seek the most convenient accommodation as close to their place of work as is practically possible. No one wants to spend all their salary and time commuting. So as we can see, architecture and planning is not just about physical infrastructure, it is much wider. These are the links that are often not presented as part of the educational process, which often exists in silos. Many countries in Africa are characterized by their macrocephaly. In Uganda, for example, as soon as you leave Kampala, there is literally nothing going on in the small towns. Some time ago there was not even a supermarket outside Kampala. Everything happened in the capital. Now, with decentralization, things could be better, but it is important to provide the secondary towns and the countryside with adequate facilities and infrastructure to limit the pressure on the big urban centers and to strengthen the links between the cities and the countryside. Currently, getting a national identity card, or a driving licence requires a trip to the capital Kampala. This is not at all practical, neither is it contributing to the idea of decentralisation. Now, in terms of education, I prefer to use education, rather than training as I believe education is a core element of higher university education. While there are elements of training within architecture and planning education, it is important that students acknowledge that their role goes beyond merely fulfilling narrowly defined objectives of individual projects, to include an appreciation of the consequences of these actions. If you look at Zanzibar, the old city - Stone Town, is among the most visited places in Tanzania. This is not because it has new glass and steel clad buildings or wide multilane roads. It is because it is at a human scale in a number of ways. It is a pedestrian environment with narrow streets, but with spaces where people can sit and talk. The soul of the community keeps it alive. The street itself is a channel of information. And that information can travel long distances because every time you walk down the street, greet people, stop, talk to them they will tell you a story. So it’s strange that we assumed that cities should be so new and glitzy. And that’s what students are unfortunately taught, to prepare to make the next tallest building, rather than getting them to understand that the way people use spaces and how they engage with the environment, is what makes the difference. Photo by Javi Lorbada on Unsplash “Adapted curricula to build more inclusive, resilient and sustainable cities in Africa…” The starting point would be thinking about the people, their climatic, cultural, social context, etc. If you start from the climate for example, the solution in Botswana can certainly not be the same solution that you have in Uganda or, in South Sudan, because these are very different situations and climates. We teach students about what is happening in the rest of the world, but very little about what is happening in the local areas. There is limited literature on the architecture of African context, so we need to write and tell the stories of and from Africa, while criticizing the things that don’t work. We are often reluctant to criticize things, just because somebody put a lot of money into it, whether it works or not. Unless we start having deep, meaningful, frank discussions about our context, we’re going to continually go down a path that doesn’t help us to build sustainably and resiliently. When you look at many urban centers across much of sub-Saharan Africa, we find an informal sector that is actually larger than the formal sector. The people who work in this grey economy are rarely if ever included in design discourse, effectively marginalised from what is perceived to be a desired future. Without an appreciation of their needs, this marginalization is set to continue with these issues brought into the mainstream of teaching and practice. In the university I work with in Uganda, the Uganda Martyrs University, we are taking students out of the classroom, to talk to the communities. For example right now, a student is working to understand how people live and how they engage in their daily activities. This bottom up approach is critical in ensuring any proposals are embedded within the community, and not cosmetic. One of the things I think is also important is to take some of the architecture schools out of the major urban areas, figuratively and practically, to get a feel for the communities and their needs. When you look at the Kwame Nkrumah University of Science and Technology in Ghana, the Copperbelt University in Zambia, and the University of Science and Technology in Zimbabwe, these are all located in secondary cities, and where the first architecture schools in these three countries were situated. This deliberate move ensures that the link between education and the lived experiences of a large proportion of the population could be better addressed. This was also the rationale for the location of the architecture school at the Uganda Martyrs University at the university’s main campus at Nkozi.. This certainly has a big impact on the shape of the education and the students that go there. So, it’s about basic things like understanding what our needs are, beyond just shelter from the elements? How do we make our urban centers work better for people? How do we make them work better in the context? Should we continue building wider roads, yet the real need is for more and efficient public transport networks? Uganda Martyrs University “Make friends, talk to people who come from different backgrounds, who have different life experiences, and travel as much as possible…” I think the very first piece of advice I would give is to be open to learning. Be open to new ideas and to constantly question preconceived ideas you may have. Beyond that, you have to understand that whatever education you get, whether it’s architecture, landscape architecture, or urban planning, it’s only education to help you start your career, it’s not the end of your education, which should continue throughout your life. This is what differentiates training from education. I also believe that students should try as much as possible to draw on their own experiences, and understand that their experience is just an individual experience, in the midst of millions of other people’s experiences. To be able to design for other people, it is important to understand and appreciate why we do things a particular way, and that this is not how millions of other people do it (for a host of different reasons). Often, I think we approach things from the perspective that our experience is the only valid one, and presume other people’s experiences and views are equal to ours. This is a consequence of the socialization process of education. For many students their experiences are narrowly defined, limiting their exposure to the diversity of experiences of others. A poingient expression of this can be found in Musa Okwonga’s memoir, ‘One of Them’. The outcomes of educational systems that derive students from a narrow group of students cannot truly address the issues of broader society. Indeed even today, some schools of architecture have intakes comprising students from a handful of secondary schools, it would be impossible for this group of students to appreciate the value of different opinions as they have never really been exposed to difference. And so my advice in this context is to make friends outside of that very narrow circle. Talk to people who come from different backgrounds, who have different life experiences, if possible, travel as much as possible whether it’s inside or outside your region or country. Many students and even professionals do not know the richness of their own country in terms of architectural and urban heritage. Knowing one’s history, heritage and environment can contribute to a better understanding of place, and space. We had great cities in Africa 300 or 400 years ago. You have Benin City in Nigeria, you have Congo City in what is now the Democratic Republic of Congo. We have Great Zimbabwe, and Bigo in Uganda ... so there are great cities that exist that we don’t hear about. Taking an interest in and learning about these early endeavours would greatly contribute to design explorations, not only in terms of form and materials, but also in terms of our ideation. Those are the key lessons I would like some people to understand.

She was awarded her PhD at the School of Higher Education Studies, University of the Free State. Tumubweinee’s commitment to architectural education has developed through her involvement as an external examiner for MProf and BHons students in Architecture at the University of Pretoria and Namibia University of Science and Technology “School of Architecture, Planning and Geomatics” The current School of Architecture, Planning and Geomatics (APG) at University of Cape Town (UCT) is the result of two mergers. The first merger took place in 1985 between the then School of Architecture and the Department of City and Regional Planning, and the second merger took place in 2002 between the School of Architecture and Planning and the Department of Geomatics. The School’s primary purpose is to produce professionals who can deal competently and creatively with the development and conservation of the built and natural environment by imagining alternative, more just and inclusive urban futures. The School of Architecture, Planning and Geomatics (APG) has a current enrolment of 667 students, 227 are registered for postgraduate degrees; of these 22 students are registered for PhDs. APG offers programmes which lead to the following qualifications: Bachelor of Architectural Studies (BAS); Bachelor of Science in Geomatics; Bachelor of Architectural Studies (Honours); Bachelor of Science (Honours) in Geographical Information Systems; Bachelor of City Planning (Honours); Bachelor of Landscape Architecture (Honours); Master of Architecture (Professional); Master of City and Regional Planning; Master of Landscape Architecture; Master of Urban Design; Master of Philosophy (MPhil) in Conservation of the Built Environment; Master of Philosophy (MPhil) in Southern Urbanism; and Opportunities to study for research-based MPhils and Doctor of Philosophy degrees. APG is located within the Faculty of Engineering and the Built Environment (EBE). Professor Alison Lewis (from the Department of Chemical Engineering) was elected as the Dean of the Faculty in 2015, and she remains in the position. All Departments and Schools within EBE offer degrees accredited by professional councils/ institutes. Processes of accreditation are recognised and supported in the Faculty and the University. EBE comprises five Departments (Construction Economics and Management; Civil Engineering; Chemical Engineering; Mechanical Engineering; and Electrical Engineering) and one School (the School of Architecture, Planning and Geomatics). In accordance with 2021 data, EBE has an enrolment of 4,452 students, of whom 1,116 are registered for postgraduate qualifications and 262 are PhD students. EBE comprises 429 academic staff and 173 professional, administrative and support staff. The Faculty has 20 active research groups, 7 SARChI chairs, 58 NRF rated staff and R220 million in research income. The undergraduate Bachelor of Architectural Studies (BAS) Programme within the School of Architecture, Planning and Geomatics (APG) provides a foundational design-oriented education from which streaming can occur into a range of postgraduate degree programmes, including the Bachelor of Architectural Studies (Honours), the Bachelor of City Planning (Honours) (linked to the Masters of City and Regional Planning) and the Bachelor of Landscape Architecture (Honours) (linked to the Masters of Landscape Architecture). These Honours level qualifications allow students to apply for the one-year Master of Urban Design (MUD) degree, a one-year MPhil specialising in the Conservation of the Built Environment and a research-based MPhil. APG also offers opportunities to register for a PhD. Furthermore, the African Centre for Cities (ACC) facilitates a coursework and dissertation MPhil on Southern Urbanism and some of these students take electives in the Planning Honours Programme. A planning stream was introduced into the undergraduate Geomatics Programme cluster in 2004. Several degree programmes in the School are recognised by professional Councils. The Masters of Architecture (Prof) degree is recognised by the South African Council for the Architectural Profession (SACAP). In addition to SACPLAN accreditation, the Planning Programme is accredited by the Royal Town Planning Institute (RTPI) ( http://www.rtpi.org.uk/ ). The combined Bachelor of Landscape Architecture (Honours) and Masters of Landscape Architecture Programme is accredited by the South African Council for the Landscape Architectural Profession (SACLAP). The MPhils are non-professional and non-accredited research degrees. “The way we educate our urban professionals on the wider continent and in South Africa is being challenged” This is not because what we teach is not good, it is because it has become increasingly difficult, within a set and structured curriculum, to address the constantly shifting dynamic nature of the urban environments we live in. Within this changing context we, as urban professionals, find ourselves confronted with how to advance appropriate theories and practices to develop a holistic understanding of the urban environment across multiple and growing disciplines and interests. This difficulty is evident in the schism between what is needed and what is done. It translates as a break between how we as academic institutions develop and train the next generation of urban professionals and the realities of the multiplicity of fundamental tools and tactics that are required to develop and implement policies and governance systems that effectively deliver for people. In part the schism stems from theories and practices that are borrowed from other times, other places and other cultures. As institutions we repackage and retrofit these theories and practices without always addressing the underlying complexities of our urban complexities and place-based realties. This calls for a “rogue” approach in the way that we train urban professionals who can contribute meaningfully in African urban environments and respond to, address and embrace a continually shifting context. This approach to training urban professionals could develop a form of urbanism that consolidates political, social, cultural and economic capital with the natural & built environment in order to bring together a conceptualisation of place and people as part of a complex world. “Rather than provide a clear ‘vision of African cities of tomorrow’, it is vital that academic institutions together with other urban professionals and civil society collectively experiment and speculate as to what an African city should look like…” The African urban terrain is complex, and because it is complex questions of sustainability, resilience, and technological development in any African city can only be speculative. This provides fertile ground from which urban professionals, and the institutions in which they are trained, can explore and experiment with alternate realities and solutions to address a variety of underlying concerns. These include climate change and resilience, significant socio-spatial inequality and poverty (tied often to colonial spatial planning), and a significant demographic youth bulge in African cities. Rather than provide a clear ‘vision’, it is vital that academic institutions together with other urban professionals and civil society collectively experiment and speculate as to what an African city should look like. For if we cannot creatively conceive of it within the specificities and peculiarities of our context, we cannot build it. In APG we aim to develop urban professionals across all programmes who can radically reshape the urban environment at all levels. This extends to, but is not limited to: 1) how we can creatively plan, design and develop our cities, towns and their neighbourhoods; 2) how we can creatively integrate combined thinking across the broadest range of disciplines involved in the urban environment – physical, socio-cultural, economic, public health, food, governance etc; 3) how can we creatively lead and manage policies and planning in the system at all levels of civil society and government. MANLIO MICHIELETTO, Dean of the School of Architecture and Built Environment (SABE) at the College of Science and Technology (CST) University of Rwanda (UR ). Manlio Michieletto is an Italian Architect graduated in 2007 from the IUAV University of Venice,and earned a PhD in Architectural Composition in 2010 from the IUAV School of Doctorate. After different academic and professional experiences in Europe (Italy and Germany) and Africa (Burkina Faso andD. R. Congo), he has since 2016 became the dean of SABE. “School of Architecture and Built Environment (SABE)..” The School of Architecture and Built Environment (SABE) started in 2009 as a faculty of architecture in the former Kigali Institute of Technology. In 2014, the government decided to unify all scattered institutes in one unique public university that is called University of Rwanda, and the Faculty of architecture became the School of Architecture and Built Environment. SABE is one of the five schools comprising the College of Science and Technology that is one of the nine colleges of the University of Rwanda. SABE is in a very inspiring compound designed by the French architect Patrick Schweitzer and our students have the opportunity to be trained in this amazing architectural artifact. The building’s aim is to be intended as an open book for students through the utilisation of different materials, construction techniques, details etc. Furthermore, it’s a passive building with no use of mechanical installation. SABE has around 1000 students and four departments (Department of Architecture, Department of construction management, Department of estate management and valuation, and the Department of geography and urban planning). These are for undergraduate programs, but we also have a post graduate program in MSc IN GEO-INFORMATION SCIENCE FOR ENVIRONMENT AND SUSTAINABLE DEVELOPMENT and we are working with partners from Europe to set up a master in architecture that will start in 2023. These programs are supervised by around 40 staff members, including junior staff, senior staff, Professor, associate professor, senior lecturer, lecturer, assistant lecturer and tutorial assistant. School of Architecture and Built Environment, Photo source SABE “We have to significantly improve the offer in terms of education to give to young people the chance to study and be actors of changes in their communities and countries…” I do think the way education in architecture and planning is made have an impact on african cities now and in the future. However, to have a positive impact, it is fundamental to establish more schools or faculties of architecture and urban studies in Africa. We can not have or continue to have countries with just one Institute or School of Architecture, urban planning, etc. To meet African cities’ challenges and turn them into opportunities, we must increase the education offered in Architecture, urban planning, and other urban studies not just in quantity, but also in quality. So, when we talk about the impact, we have first to significantly improve the offer in terms of education to give to young people the chance to study and be actors of changes in their communities and countries. African cities are a bit wider as a concept, so we cannot compare Ouagadougou with Lagos or Lome with Kinshasa, etc. I think for training in architecture in Africa, the undergraduate students have to be trained as any other students over the world, then, specialize themself through for example, postgraduate programs on the local context. At SABE, we try to introduce in the existing curricula the analysis and the study of the local context, to train students able -after an undergraduate degree, to appropriately manage a project in the local context. African cities are very different in shape, in size, etc. So, African students have to learn critical methods that enable them to have a holistic overview of the context. They have to be able to build a critical point of view, train their eyes to understand the context, identify problems and find the appropriate solutions. “At SABE there is a constant relationship between teaching activities and local context…” Lectures are normally based on tropical architecture and urban design, that means the architecture adapted to the local environment and context. We also teach students history of architecture and theory of architecture including the relationship between the city, and the built environment. So students move from universal theories of architecture and urban planning to theories of African cities, from tropical villages to African architecture. We also use resources to equip our students with theoretical and practical knowledge like books on African cities, UN-Habitat rules and principles, and the Green Council buildings rules that the Rwandan government established for the construction of green buildings in Rwanda. So, for us at SABE there is a constant relationship between teaching activities and local context. For example, in the Department of Geography, urban planning, students always have practical workshops on the local context, with the local community involved, population, local stakeholders etc. We also have summer workshops that are targeting real issues or challenges in kigali to not only have students adapted to the local context, but also to the local market. Furthermore, during their training, our students have to do professional internships for the fourth and fifth year. All these help them to be adapted to market needs. We have been asked by our university to move to a problem based learning teaching system, which means that all our modules, especially for assessment and final examination, have to be based on problem based learning or a challenge driven education. So we have the theoretical part of the module, and then a practical one based on a real problem that students may identify in their context. The students work in groups to propose a solution to a real problem, starting from problem identification to an adapted solution. “I see the future of African cities in the past…” First of all, we have to be conscious of our past. The African city is rich in history and heritage that have shaped its evolution over time. This ancestral African city has always been smart and sustainable. It is therefore important to go back to this history and heritage to build the African city and not to import models from elsewhere. The second important thing in this context of rapid growth and urbanization is to train local actors who understand the context. It is a question of training city actors (architects, urban planners, designers, etc.) at the local level with local knowledge and know-how because they know their history, they have grown up in these cities and are the best able to understand the problems and to provide solutions. Another fundamental aspect to take into account for the African sustainable city is the political will. We can see that the great cities throughout the world were mostly built by political vision. Therefore, in Africa, it is important that the leaders draw a shared vision of the sustainable city and take the necessary means to achieve the objectives of the sustainable city. “Be committed and passionate about what they are doing…” My advice for young students is to really be committed and passionate about what they are doing, because it is the only way to achieve good results, in all aspects of their life. MOUSSA DEMBELE, Malian Architect graduated in architecture from Xinghua University in China. He worked as an architect for 4 years in Singapore, then obtained his doctorate from the Kyoto Institute of Technology in Japan. After teaching for several years in Japan and China, he opened an architectural office in Mali before being appointed in 2015 as the General Manager of EAMAU. “Tell us about the African School of Architecture and Urbanism…” The African School of Architecture and Urban Planning (EAMAU) is an inter-state institution that brings together 8 countries of the UEMOA (Benin, Burkina Faso, Côte d’Ivoire, Guinea Bissau, Mali, Niger, Senegal, Togo) and the 6 countries of the CEMAC (Cameroon, Central African Republic, Congo, Gabon, Equatorial Guinea, Chad). It was created under the will of the heads of state in order to train young people to face the urbanization of African cities in 1975. In view of the challenges facing African cities in terms of urbanization, it can be said that this vision of member states through EAMAU is more than salutary in order to meet the challenges posed by the rapid urban growth of the continent by training local actors on urban issues. To this end, EAMAU trains architects, urban planners, and urban managers through Bachelor’s, Master’s, and Doctoral training cycles. The training courses are both theoretical and practical and lead the learners to the professional-grade after 5 years of study. The training method equips them with tools that enable them to practice the profession in an operational manner in different African countries, particularly with field training courses throughout the training program. African School of Architecture and Urbanism, Photo by G2L-PHOTOGRAPHY “It is crucial to train professionals capable of facing the challenges of the continent in terms of urban development…” With more than 1400 high-level graduates, who continue to shape the political, economic, and cultural landscape in African countries, EAMAU is an institution that is constantly adapting to best meet the challenges of the continent. Indeed, we have moved from the great canons of education in architecture and urban planning to the Bachelor’s Degree Master’s Doctorate (LMD) system in 2010. In addition, the diplomas of EAMAU have been accredited by the African and Malagasy Council for Education (CAMES), and our institution has been for the occasion retained as a reference school for the training of architects and urbanists. It is, therefore, necessary to adapt constantly to produce professionals capable of facing the challenges of the continent in terms of urban development. As we can see, the continent is experiencing rapid urban growth, and many factors are influencing this growth, so it must be directed and controlled so that cities are spaces of well-being, inclusion, social peace, economic prosperity, and offer a healthy and preserved living environment. This is why we put a particular emphasis on providing our learners with key and contextual tools through our training to achieve these objectives. “Train professionals able to respond to global issues…” EAMAU today has a scope that extends beyond the member countries by training actors from the whole continent and the rest of the world. This is how we keep an open mind on the world, by adapting and innovating, to train professionals able to respond to global issues related to digital development, climate issues, environmental protection, etc. However, we make it a point to ensure that our students have this understanding, the very expression and specificity of Africa in the training. It is in this context that our students do fieldwork each year to diagnose problems in African cities, and these problems are transcribed into concrete and local solutions through projects. Thus, the projects proposed by the students are the result of a concrete and pragmatic approach to research in order to respond specifically to the challenges of African cities. The teaching methods within our institution converge towards excellence through the international character of the students, the transversality of the teachings, and the projects that are developed by the learners. This is so that the school is at the service of the States for the development of our countries. It is in this context that we develop training that can lead to projects that will allow States to modernize their development and economic take-off. We have introduced in this context a very important phase which is research. Today no institution, no field can develop without research and in our context this research component allows us to address in-depth the issue of African architectural and urban heritage. Africa is endowed with an immense heritage that can be considered open-air museums. The question is what can we draw from this heritage to build more sustainable and resilient cities? It is with a view to answering these questions that we are developing the research aspect in order to effectively produce reflections that contribute to setting up human settlements adapted to the African context. For the history of cities and civilizations millennia African abounds in examples in terms of sustainability, and resilience through the use of local materials, functional organization of spaces, waste management, environmental preservation, etc. The approach here is through research to draw from this rich heritage to develop modern solutions adapted to the social, cultural, economic, and geographical context of our cities. “Students and young professionals across the continent have the mission of build more sustainable and resilient cities in Africa…” We think that the objective for graduates should not only be to work in architecture or urban planning agencies, but to get involved in the high levels of administration, banking institutions, international organizations because they have the resources to do so. It is for them to be a force of proposal, not to evolve in a vacuum, to inform themselves, to travel to build more sustainable and resilient cities in Africa. Previous Next

< Back Urbanisme tactique : les artefacts urbains comme vecteur de mobilité durable pour une meilleure qualité de l’air dans la ville de Yaoundé Cedrix and Christolle Tsambang Les artefacts urbains, inspirés des symboles locaux et fabriqués en bambou, offrent une alternative durable, abordable et écologique pour un cadre de vie plus sain. Conçus pour encourager la marche et l'utilisation des transports en commun, ces installations éphémères s'intègrent harmonieusement dans l'espace urbain. La fermeture temporaire d'une voie de l'avenue Kennedy a incité les habitants à adopter des modes de déplacement doux, réduisant ainsi les émissions polluantes. Cette démarche souligne l'importance de repenser l'aménagement urbain pour favoriser la mobilité durable et préserver la qualité de l'air. En impliquant les artisans locaux et en utilisant des matériaux biosourcés, cette initiative contribue également au développement économique et à la protection de l'environnement. L'expérience de l'avenue Kennedy démontre le potentiel des équipements urbains pour dynamiser les espaces publics et créer des villes africaines durables et attrayantes. Une meilleure qualité de vie dans les villes africaines passe par la création d’un cadre de vie plus sain en repensant les pratiques notamment en matière de mobilité urbaine. C’est dans cette optique que s’inscrit les artefacts urbains développés par chorus architecture le long de l’avenue Kennedy de Yaoundé au Cameroun à l’occasion de la semaine de la qualité de l’air. Il s’agit d’une scénographie inspirée de symboles locaux obtenus par une combinaison contemporaine de lignes ou de faces en tiges de bambou. Le bambou plébiscité pour ses propriétés et son attrait dans la mutation vers une architecture durable se présente ici comme une alternative verte, accessible, disponible et abordable. Plus que de simples mobiliers urbains, les installations éphémères conçues sont le reflet du lieu. Vue sur l'avenue kennedy réamenagé, 2021, alaray studio Les artefacts urbains ont été conçu pour la mise en place d’une Opération d’urbanisme tactique qui entre dans le cadre de la réalisation des actions à court terme du projet de mise en place des outils de lutte contre la pollution atmosphérique dans la ville de Yaoundé. Au cœur de l’enjeu de transition écologique, la qualité de l’air apparaît comme un sujet très important pour la protection environnementale. Mettre sur pied une politique en faveur de la protection de la qualité de l’air doit s’inscrire dans une dynamique globale et nécessite des actions ambitieuses à toutes les échelles, afin de garantir à chacun le droit de respirer un air qui ne nuise pas à sa santé. Le concept de mobilité durable comprend une réflexion sur l’environnement et les problématiques de développement durable en repensant l’aménagement du territoire et de l’espace urbain. Il s’agit de limiter l’empreinte carbone et de réduire les inégalités territoriales dans les zones mal desservies par les transports, en mettant en place des solutions qui favorisent le recours aux mobilités douces. Le dispositif de lutte contre la pollution de l’air dans ce projet s’organise autour de la réduction des émissions atmosphériques causé principalement par le trafic routier, source importante d’émissions d’oxyde d’azote. L’augmentation de l’utilisation des transports en commun engendre un désengorgement sur les routes et réduit donc les substances polluantes dans l’air. Dans le centre-ville de Yaoundé les principaux transports en communs sont les taxis et les bus. Encourager à la marche serait également moyen d’améliorer la qualité de l’air tout en étant un excellent moyen de se maintenir en forme, de s’évader du quotidien tout en respectant l’environnement. Le choix du site n’est pas anodin, l’avenue Kennedy lieu mythique de la capitale est situé en plein cœur de Yaoundé et est un endroit très indiqué pour un projet de sensibilisation car toutes les couches sociales s’y côtoient. L’objectif des artefacts urbains est de contribuer à aménager des espaces urbains favorables à la mobilité douce tout en mesurant grâce à des capteurs la qualité de l’air. Il était donc question de fermer l’accès aux véhicules sur une des voies de l’avenue Kennedy pendant deux semaines afin d’inciter les habitants de la ville à plus de marche à pied et l’utilisation des transports en communs. Afin de favoriser une marche agréable et effective sur une avenue de plusieurs kilomètres tel que celle de l’avenue Kennedy il est important de créer des zones de rupture, de pause : créer des obstacles tels que des mobiliers urbains utiles afin d’agrémenter la marche et la rendre dynamique. Le mobilier urbain est donc tout à la fois porteur d’une approche fonctionnaliste et le vecteur d’une identité du projet. Le mobilier de l’espace public fait d’ailleurs aujourd’hui l’objet d’attentes qualitatives fortes en tant que véritable outil d’aménagement urbain. Il existe dans la définition même du terme « mobilier urbain » la volonté d’harmonisation, d’homogénéisation et d’appartenance : des objets rendant service, venant faciliter et embellir la vie des citoyens d’une ville. Pourtant, il semble que le mobilier urbain lorsqu’il existe est trop souvent le produit d’usages spécifiques très déterminés, qui ne laisse pas suffisamment place à des questions plus larges sur la nature de ces usages mêmes. Chorus architecture a donc designer des artefacts en guise de mobiliers urbains afin de susciter de l’interrogation, de la surprise et de la curiosité pour expérimenter de nouvelles pratiques et mettre sur pied de nouveaux concepts en amenant à remettre en question notre compréhension de la réalité afin de réintroduire l’humain dans l’urbain. Conçus et fabriqués localement avec des matériaux biosourcés de ces artefacts urbains ont permis de développer et mettre en avant le savoir-faire local en intégrant différents types d’artisans, créer des emplois tout en participant à la protection de l’environnement. En optant pour du mobilier en bambou, les artefacts concilient élégance, originalité et engagement contre la déforestation dans une perspective de développement durable. Vue sur une partie de la scénographie, 2021, alaray studio Grace aux capteurs installés dans la zone, il a été clairement démontré que la qualité de l’air à considérablement été améliorer durant ces deux semaines d’études. Ceci permet de constater l’impact sur la circulation automobile dans la ville et révéler l’importance et surtout l’efficacité des aménagements effectués. L’attrait généré par l’installation de ces équipements urbains démontre de la nécessité de réinventer nos villes en mettant un accent sur la conception de détails dans les espaces publics. De plus, des équipements urbains comme ceux-là constituent une plus-value notable pour les municipalités, et ce, quelle que soit leur taille ou leur importance. Si certains éléments présentent un aspect pratique, comme ces mobiliers urbains, de nombreux autres aménagements peuvent permettre de dynamiser la vie communale. Penser des villes africaines durables passent également par la re conception des espaces publics en mettant un accent sur l’intégration des éléments qui interpellent et qui communiquent. Cette expérience à l’avenue permet de constater qu’il est possible d’utiliser le savoir-faire local ainsi que les matériaux locaux pour créer des mobiliers urbains intéressant et respectueux de l’environnement.

< Back La géopolitique de la gouvernance urbaine – une approche innovante pour coproduire des connaissances Sina Schlimmer L'Institut français des relations internationales (Ifri) lance un programme de recherche intitulé « Gouverner la transition urbaine en Afrique » pour aborder la compétition géopolitique croissante autour des infrastructures urbaines et les approches de gouvernance innovantes pour les villes de taille moyenne en Afrique. Ce programme vise à créer des connaissances sur la gouvernance urbaine en développant des approches qui lient recherche, utilité sociale et action concrète. Lancé en 2022, il se concentrera sur des études continentales, régionales, nationales et de quartiers, abordant trois domaines clés interconnectés de la gouvernance urbaine : le foncier, la mobilité et les infrastructures. Le programme traitera également des besoins en matière de financement des infrastructures, des questions foncières et de mobilité à travers des études de cas issues de capitales et de villes de taille moyenne en Côte d'Ivoire, au Kenya, au Nigeria, au Sénégal et en Tanzanie. Il vise aussi à briser les frontières de la connaissance entre le « Sud global » et le « Nord global » en intégrant les perspectives des acteurs de différents secteurs professionnels liés à la gouvernance urbaine dans la conception de la recherche. Le nombre d'initiatives de recherche sur les villes africaines et sur la manière de réguler leur croissance ne cesse de croître. De nombreux acteurs contribuent à la gouvernance urbaine et beaucoup mènent leurs propres collectes de données et produisent des résultats de recherche. Cependant, les canaux et les interactions entre ces organisations et experts restent souvent limités et sous-exploités. Ce programme de recherche, lancé par l'Ifri en mai 2022, a pour objectif de fournir une plateforme permettant à ces acteurs de se rencontrer, de partager leur expertise et de coproduire des connaissances dans trois domaines clés interconnectés de la gouvernance urbaine : le foncier, la mobilité et les infrastructures. Le programme repose sur un consortium multipartite dont les membres sont des chercheurs, des décideurs locaux et nationaux, des organisations de la société civile et des fondations, des agences de développement, des organisations internationales, des corps professionnels et des acteurs du secteur privé, tous directement impliqués dans différents secteurs et activités liés à la gouvernance urbaine. Les réflexions transversales, les ateliers de recherche, les publications et des événements plus classiques, comme des webinaires et des conférences organisés dans des villes européennes et africaines, seront les principaux composants du programme. Les activités de la première année se concentreront sur les politiques de gouvernance urbaine, la concurrence géopolitique croissante autour des infrastructures urbaines et les approches de gouvernance innovantes pour les villes de taille moyenne. Au cours de la dernière décennie, la croissance urbaine en Afrique a suscité une grande attention de la communauté internationale. Plus particulièrement, depuis que l'objectif de créer des villes inclusives et durables a été inclus dans la liste des 17 Objectifs de développement durable en 2015, divers acteurs de différents secteurs (privé, agences de donateurs bilatéraux et multilatéraux, société civile et mouvements de base, municipalités, gouvernements nationaux, etc.) et à différents niveaux (local, national et international) ont développé des programmes, lancé des initiatives et construit leurs agendas autour des dynamiques d'urbanisation sur le continent. Des programmes de politiques, des projets de développement, des initiatives de diplomatie municipale, mais aussi des modèles d'investissement et de financement – tous visant à contribuer au développement urbain du continent – ont été conçus et mis en œuvre par de nombreux types d'acteurs et d'institutions. Ensemble, ils forment un réseau dense et multi-échelle d'acteurs, d'initiatives, de relations et de compétitions qui constituent et caractérisent la gouvernance urbaine (Förster, Amman, 2018; Bekker, Fourchard, 2013, Myers, 2011). ] Les initiatives de recherche traitant de la transformation des villes africaines augmentent également, mais ne sont pas récentes. Des chercheurs issus de multiples disciplines – en particulier dans les universités occidentales – produisent des connaissances, notamment depuis les années 1950. Ce corpus comprend de nombreux débats sur la nature, les acteurs et, dans une certaine mesure, la politique de la gouvernance urbaine (voir un aperçu de la littérature dans Schlimmer, 2022). Mais la production de connaissances sur les villes africaines et la gouvernance urbaine n'est pas un domaine exclusif des salles de séminaires et des revues académiques : des agences de développement, des organisations de la société civile spécialisées, des réseaux internationaux (UCGL, FMDV, etc.) et des corps professionnels ont produit des rapports contenant des informations empiriques précieuses, basées sur des collectes de données quantitatives et qualitatives ou des restitutions d’événements. En résumé : autant les acteurs impliqués dans la gouvernance des villes africaines sont nombreux, autant les initiatives de recherche créent de la sensibilisation et des données. Dans ce contexte de débats vifs et d'expertise croissante, deux grands problèmes se posent : le premier est la communication limitée et la collaboration restreinte entre les membres de cette communauté de recherche et de gouvernance urbaine. Chaque institution étant absorbée par ses propres agendas, objectifs et centres d'intérêt, il peut être difficile d'identifier des initiatives de recherche similaires menées par d'autres organisations. Deuxièmement, il est de notoriété commune qu’après leur publication, certaines données et rapports restent inexploités tandis que de nouveaux projets et initiatives de recherche sont déjà en préparation. En lien avec ce problème, certaines institutions réfléchissent à la manière d’améliorer la promotion et l’élargissement de la diffusion de leurs produits de recherche. Le programme de recherche sur « Gouverner la transition urbaine en Afrique » coordonné par l'Institut français des relations internationales (Ifri) vise à créer des connaissances sur la gouvernance urbaine en développant des approches pour aborder ces questions, qui concernent le lien entre la recherche, son utilité sociale et l’action concrète. L'architecture même du programme reflète cette approche de recherche orientée vers la résolution de problèmes : elle repose sur l’objectif de coproduire des connaissances avec différents acteurs clés impliqués dans la gouvernance urbaine, tant à l’international, qu’au niveau bilatéral et national. À partir de 2022, le projet se concentrera sur des études continentales, régionales, nationales (Côte d'Ivoire, Kenya, Nigeria, Sénégal et Tanzanie) et locales portant sur trois domaines interconnectés de la gouvernance urbaine : le foncier, la mobilité et les infrastructures. L’un des principaux sujets de la première année est l’accent croissant mis par les gouvernements, la communauté internationale, mais aussi les entreprises, sur la promotion des villes de taille moyenne et des nouvelles villes. Les publications porteront, par exemple, sur les enseignements tirés du projet de « nouvelle ville » à Diamniadio. Initialement annoncé comme une initiative pour décongestionner la capitale sénégalaise Dakar, des rapports et discours sur son caractère de ville fantôme et la viabilité limitée des créations urbaines ex nihilo se multiplient. Une autre recherche porte sur les villes de taille moyenne au Nigeria, où la recherche sur les politiques urbaines s’est largement concentrée sur la croissance exponentielle de la mégapole Lagos. Les résultats de cette recherche seront présentés et discutés lors de webinaires impliquant des décideurs et des experts des pays concernés. Le centre Afrique subsaharienne de l'Ifri organise un programme de recherche sur les grands défis des transitions urbaines en Afrique (2022-2024). Il a mis en place un consortium composé d'experts d'organisations internationales, des pays cibles de l'étude, ainsi que de la France et de l'Allemagne (et le réseau est encore en expansion), qui couvrent les domaines professionnels suivants : organisations internationales multilatérales et clés dans le domaine de la gouvernance urbaine en Afrique, agences de développement bilatérales, institutions académiques, secteur privé/entreprises impliquées dans le développement des infrastructures urbaines, maires, corps professionnels (par exemple dans les domaines du foncier et de l’urbanisme), ainsi que des fondations et des organisations de la société civile. Avant la création du consortium, une phase de consultation d'un an avec des parties prenantes basées en France, en Allemagne et au Kenya a permis de rencontrer et de discuter avec des chercheurs, des experts et des représentants de différentes institutions afin de comprendre leurs approches et définitions de la gouvernance urbaine, d’en apprendre davantage sur leurs activités et d’identifier leurs besoins en termes de production et de diffusion de connaissances de leurs propres initiatives de recherche. Sur la base de ces entretiens et de ces sessions de travail avec les membres du consortium, une carte des initiatives et données existantes a été créée, des idées pour accroître leur impact et étendre leur portée ont été développées, et un pool de domaines de recherche qui restent à aborder a été établi. Il est nécessaire de mieux comprendre les questions foncières, le financement des infrastructures et la mobilité, que ce programme abordera à travers des études de cas portant sur des capitales et des villes de taille moyenne en Côte d'Ivoire, au Kenya, au Nigeria, au Sénégal et en Tanzanie. La coproduction de connaissances est le concept clé de ce consortium. Elle sera mise en œuvre à travers différentes méthodes de collecte de données, d'analyse et de diffusion de la recherche. “Ateliers multi-acteurs sur différents aspects de la gouvernance urbaine” En plus des webinaires classiques et d'une conférence annuelle organisée à tour de rôle dans une ville européenne et une ville africaine, les ateliers seront des moments clés pour coproduire, partager et échanger. Les partenaires du consortium se réuniront pour discuter de sujets sélectionnés. Durant la première année du programme, les événements porteront sur le financement durable des projets de « nouvelles villes ». Basé sur l’expérience de l’Ifri en tant que think tank leader sur les relations internationales, l’événement abordera la question du financement des infrastructures urbaines en tant que terrain fertile pour la concurrence géopolitique, à mesure que le nombre de partenariats public-privé (PPP) et d’accords de financement entre les gouvernements africains et des partenaires « traditionnels » et « nouveaux » (par exemple, la Turquie, les États du Golfe, la Chine) augmente. Un autre webinaire abordera différentes approches de la gouvernance urbaine dans les villes de taille moyenne, y compris la coopération décentralisée et la diplomatie des villes. Lors de ces événements, les participants partageront leurs expériences professionnelles quotidiennes en les confrontant aux perspectives et analyses d’experts et de chercheurs. Inversement, les chercheurs et experts auront l’occasion de se rapprocher des professionnels, praticiens et décideurs impliqués dans les secteurs foncier, de la mobilité et des infrastructures de la gouvernance urbaine. L'objectif est de créer un environnement d'apprentissage constructif, où tous les participants cherchent à dépasser les frontières institutionnelles et les cloisonnements thématiques. Briser les frontières de la connaissance entre le « Sud global » et le « Nord global » L’une des principales observations de la recherche sur les villes africaines est que les outils de gouvernance et de planification, les normes et les modèles sont largement inspirés d’approches occidentales, dont certaines se sont révélées incompatibles avec les réalités de la vie urbaine sur le terrain (Lindell, 2008). Le pool de chercheurs et d’experts impliqués dans le programme a travaillé dans des institutions internationales, africaines et européennes et acquis de l’expérience dans la création de villes dans différents contextes. Ils contribueront aux discussions transversales et déconstruiront les approches dominantes. Les articles comparatifs et coécrits confrontant des études de cas et croisant des approches disciplinaires sont encouragés. Les produits de recherche se concentreront sur différentes échelles d'analyse allant du niveau continental au niveau local. “Un réseau croissant de chercheurs, d'experts et de professionnels” Le consortium et les événements qui seront organisés sont conçus comme une plateforme d'échange, d'apprentissage et de mise en réseau. Le réseau se développera au fil du temps en incluant davantage d'institutions, d'experts et en particulier de jeunes chercheurs intéressés par une recherche novatrice axée sur les politiques et les actions en matière de gouvernance urbaine. Les praticiens de différents secteurs urbains soulignent parfois les impacts limités, directs et mesurables, de la recherche sur les projets urbains et les communautés cibles. Bien que ce programme de recherche n’ait pas pour objectif de formuler des solutions fixes et compactes pour la gouvernance urbaine, sa fondation sur un consortium multi-acteurs facilitera l'accessibilité et la compréhension des résultats de la recherche par un public non académique et orienté vers l'action, augmentant ainsi sa signification. Notre approche de coproduction aidera à inclure les perspectives des parties prenantes de différents domaines professionnels liés à la gouvernance urbaine dans la conception de la recherche. Les perspectives et connaissances créées se diffuseront à travers les activités et approches du programme : Événements de restitution : La plupart des études publiées (formats longs et courts), publiées en anglais et en français, seront présentées par leurs auteurs lors de cycles de webinaires et/ou lors de la conférence annuelle ouverte au grand public. La première conférence annuelle est prévue à Dakar en 2023 et réunira des experts et de jeunes chercheurs de la région pour partager des connaissances et discuter des défis liés au foncier, aux infrastructures et à la mobilité dans les projets de nouvelles villes établis dans la région. Certaines des recherches menées seront également présentées lors de petits ateliers multi-acteurs, où les praticiens du consortium pourront directement partager leurs préoccupations quant à la pertinence et à la réutilisation des résultats de la recherche dans leur travail quotidien. Si des fonds sont disponibles, des événements de restitution régionaux et locaux permettront à la population cible de projets urbains spécifiques, ainsi qu'aux représentants de la société civile et des mouvements de base, de partager leurs commentaires et d'évaluer la signification des résultats de la recherche. Collaborations scientifiques entre différentes institutions d'apprentissage : dans la mesure où les sujets le permettent, nos chercheurs seront encouragés à coécrire leurs articles avec des collègues d’autres instituts de recherche, afin de favoriser les synergies entre les institutions d’apprentissage et d’élargir le réseau. L'Ifri collabore étroitement avec les Instituts français de recherche à l'étranger (UMIFRE), qui sont des plateformes renforçant la collaboration scientifique entre les chercheurs français et les laboratoires de recherche du monde entier. Les bureaux à Nairobi, au Kenya, et à Ibadan, au Nigeria, sont des partenaires proches qui nous aident à identifier de jeunes chercheurs et experts ainsi que des initiatives de recherche traitant de sujets liés à la gouvernance urbaine. Membres actifs du consortium représentés dans nos pays cibles d’étude : en plus des chercheurs qui mènent des travaux de terrain, le consortium de recherche est composé d'organisations internationales, d'agences de développement, de fondations et d'entreprises ayant des bureaux dans nos différents pays cibles d'étude. Ils sont concrètement impliqués dans différents aspects de la gouvernance urbaine, tels que la formulation de politiques, l’urbanisme, le financement, la conception et la mise en œuvre d’infrastructures, mais aussi le soutien aux organisations de la société civile. La présence active de nos partenaires sur le terrain, y compris des chercheurs, ONU-Habitat, la Fondation Friedrich-Ebert, l'Agence française de développement, mais aussi Bureau Veritas, Egis, Meridiam, Orange et la Société, est cruciale lors de la diffusion de nos résultats de recherche, lors de leurs propres événements et activités, mais aussi lors de la coorganisation de séminaires de restitution sur place. Ils serviront également de nœuds pour les réseaux locaux que nous entendons construire et étendre pendant le programme. Conçu comme un consortium de recherche multi-acteurs, notre programme est une initiative novatrice qui vise à exploiter l'expertise des différentes parties prenantes impliquées dans la gouvernance urbaine pour coproduire une recherche pertinente et socialement utile. Après un an de revue de la littérature, de réseautage et de plusieurs séries de réunions de consultation, le programme de recherche « Gouverner la transition urbaine en Afrique » a été lancé en mai 2022 à l’Ifri à Paris. Les membres du consortium se sont réunis pour préparer et valider la feuille de route de la première année du programme et ont décidé à la fois du programme de recherche et des événements à organiser. Le foncier, les infrastructures et la mobilité seront traités comme des domaines clés interconnectés de la gouvernance urbaine. L’évaluation de ces secteurs est particulièrement pertinente dans les villes de taille moyenne, qui reflètent certains des taux de croissance urbaine les plus élevés du continent. L'agenda de la première année met également l'accent sur la politique de la gouvernance urbaine, y compris la concurrence géopolitique croissante autour des projets d'infrastructures urbaines par des pays partenaires dits « traditionnels » et « émergents ». La fondation du consortium de recherche a été lancée, mais il ne peut vivre et se développer que si d'autres experts, chercheurs et partenaires rejoignent l’aventure et alimentent nos réflexions et débats sur la gouvernance urbaine tout au long de sa mise en œuvre.

< Back Cameroon museums: The language of symbols for cosmo-architecture The Route des Chefferies is a program in Cameroon that focuses on safeguarding and promoting heritage for over twenty years. It aims to restore and create spaces that promote the heritage of populations, chiefdoms, and the region as a whole. The program has led to the nomination of several traditional buildings to the World Heritage list with UNESCO. The contemporary architecture of the museums and heritage huts is inspired by the traditional aspects of the Grassfields, contributing to the scenographic development of the territory. The Museum of Civilizations is an interpretation center of Cameroonian civilizations, open to the public since 2010. It features a nautical base, beach volleyball court, playground, craft center, and a Garden of Civilizations. The Royal Museum of Foumban combines tradition and modernity, featuring the coat of arms of the Bamoun Sultanate. The Bamendjinda community museum highlights the specificities of the Bamendjinda chiefdom under the theme "Arts-Tradition and Slavery." The Route des Chefferies is a program of safeguarding and promotion of heritage in Cameroon, which, for about twenty years. It works in the restoration and creation of spaces aimed at promoting the heritage of the populations, the chiefdoms, and the region as a whole. This program, innovative in Africa, integrates a large pole dedicated to the development of the territory, to architecture, and to the design of heritage. This pole works on the cultural and tourist development of the territory by proposing buildings and places imbued with an «African» scenography that allows for the reinforcement of a rural cultural centrality. The urbanity here is specific because it navigates in a world where the living rub shoulders with the world of the ancestors, the invisible world. It also contributes to the rehabilitation of traditional buildings in danger, and participates in their safeguard in the case of various programs. Thus, since 2018, the restoration work carried out by several chieftaincies has led to the nomination of several traditional buildings (traditional palaces of Bandjoun, Bapa, Batoufam, Mankon, Bafut ...) to the list of World Heritage with UNESCO. The contemporary architecture of the museums and heritage huts (14 heritage huts have been built to date) is fundamentally inspired by the traditional aspects of the Grassfields, which will be recalled in the first part of this article, in order to contribute to the scenographic development of the territory, notably through the creation of cultural buildings detailed in the second part, all within the framework of work in communion with local craftsmen and artists, but also with the elements offered by nature in the Grassfields. The Museum of Civilization The Museum of Civilizations is an interpretation center of the civilizations of Cameroon open to the public since November 20, 2010. This building, located on the shores of Lake Dschang, has become an authentic place of leisure and culture thanks to its nautical base (2005), its beach volleyball court, its playground (2006), its craft center (2010) and very soon a Garden of Civilizations. After an introductory presentation of Cameroon over the centuries, the visitor is invited to discover the Cameroonian people in its identity both plural and fusional: the peoples of the forest with their totemic expression, the peoples of the sea with the revival of the Ngondo cultural festival, the Sudanese-Sahelian peoples with their lamidats, chieftaincies, sultanates and the peoples of Grassfield with their mysterious chieftaincies. It is an interpretation center that promotes an integrated approach to cultural heritage that allows visitors, especially local communities, to reconnect with their roots while learning about the cultures of other regions. This approach is part of cultural tolerance, an important vector of cultural diversity. The contemporary African architecture, signed by the architect Sylvain Djache Nzefa, founder of La Route des Chefferies, is characterized by the symphony of symbols: spider, buffalo, elephant woman, Abbia jettons, and local languages. The Museum of Civilization, with its multiple functions, is endowed with history, knowledge, and intelligence. In the world of the living, in the Bamileke cosmogony, men and animals dialogue, and this dialogue is also done in representation. Among the living, the one who possesses the sum of all experiences is the old man. Everywhere in Black Africa, the old man «was» considered to be the wise man, the connoisseur, the one who «held» the truth, through his multiple experiences. It is his knowledge that is symbolized through the spider. According to Pierre Harter: The spider-mygale, symbol of knowledge, often takes the form of a small single or double circle, with four crossed legs and not eight, which makes it possible to compose on certain mask headdresses or certain engravings of libation horns, a sort of diamond or square mesh net. The spider thus appears as the central element of the architecture of the Museum of Civilization: it is taken here as an architectural element that gives rhythm to the façade. The façade is treated as a mask through blue moldings. There is a desire to hide what is behind. Let us not forget that in the Negro-African, the masks speak; the wearer is possessed by his mask. Here, the wearer is the museum. The mask representing the spider expresses the contents of this building, that is, knowledge. The buffalo and elephant masks symbolize strength, power, grandeur, and wealth. Another façade of the museum is covered with alphabets and the word «welcome» written in several languages and dialects spoken in Cameroon. The eye is busy here capturing the multitude of information, codes, landmarks, which are symbols representing the objectives, the roles of the building namely: educate, preserve, transmit, innovate... Through these symbols, a man approaches what is knowledge, intelligence, society, cosmology, and cosmogony. The motifs used for the moldings on the facades are stylized forms of masks, motifs such as the spider, the buffalo, the woman, and the elephant. The act of building or conceptualizing objects and habitats is seen as a support for knowledge and understanding of the other. It leads to a review of all that is at stake in the constitution and foundations of the different civilizations of Cameroon. The visitor is thus led to question his cultural identity by a better knowledge of himself, which facilitates in principle the dialogue between civilizations. The Museum of Civilization is developing an African museographic experience that aims to put the public at the heart of the process through didactic support and contextual settings that allow visitors to immerse themselves in the heart of Cameroonian cultures. It is not so much a matter of showing as of creating an experience of a visit by provoking sensations and emotions. Realized by a Franco-Cameroonian team, the content of the exhibition is based on a scientific and interdisciplinary approach (history, archaeology, ethnography, sociology, architecture, and heritage...). Dynamic and educational. The exhibition has been conceived, in space and time, in such a way as to integrate current events. With more than 500 objects, 1500 illustrations, video spaces, the museography integrates in an important way the traditional African materials worked in a contemporary approach by the local craftsmen (varnished or burned bamboo, banana bark, obom bark, cowries, beads, raffia, earth, coconuts...) This is the first time that we discover how traditional skills can be highlighted in contemporary scenography. The Museum of Civilizations does not find its justification in the existence of a collection of objects of its own; the pieces presented illustrate the discourse chosen by the designers and come mostly from loans and deposits of the chieftaincies. Royal Museum of Foumban The Bamoun Sultanate is located in the Western Region of the Republic of Cameroon in Central Africa. The Sultanate is at an altitude of 1200 meters and covers an area of 7,625 Km². The current Sultan, Ibrahim MBOUOMBOUO NJOYA, 19th of this dynasty, animated by the immeasurable concern to safeguard this rich multi secular heritage bequeathed by his ancestors, has undertaken for nearly two years, the construction of a new museum adapted to the museum rules and spacious enough to contain all the objects of the collection. The architect Issofa MBOUOMBOUO has thought of a symbolic architecture that combines tradition and modernity and which, in itself, is enough to be a museum. This symbolic architecture is a set composed of the coat of arms of the Kingdom such as: 1 - Double bell: Symbol of patriotism. It is an instrument used by the King to stimulate and galvanize his troops at the front. 2 - The spider: Symbol of work. The King wants his people to be as hardworking as the spider who spends all his time weaving webs. 3 - Snake with two heads : Symbol of the simultaneous victory of the Bamoun people on two fronts. It symbolizes the power of the Kingdom. The result of this masterpiece is the first vector of communication of this museum, through its cosmogonic architecture, following the example of the Museum of Civilization in Dschang. Heritage hut, community museum of the Bamendjinda chiefdom: art, tradition and slavery Its permanent exhibition, unique in the region and in Cameroon, highlights all the specificities of Bamendjinda under the theme «ARTS-TRADITION AND SLAVERY». The Bamendjinda chieftaincy has been marked by slavery, whether it be slave trade or customary slavery. Some cultures still commemorate this past. Its historical and social consequences are perceptible in its plastic production, in its cultural expressions, in the organization and functioning of its chieftaincy. SM TANEFO, the current chief of the Bamendjinda, actively participates in the work of memory on this part of the history of Cameroon. The Bamendjinda community museum plays a role in the collective memory at the social, cultural, educational, and economic levels. Through objects, illustrations, paintings, videos, and a library, this museum is accessible to the general public. It is playful, complete, and enhances the cultural heritage of the chiefdom. The visitor, through the decorations, is led to discover not only Bamendjinda from its origins to today, but also the history that has marked the social organization of the chieftaincies of the West and of Cameroon. The architect Sylvain DJACHE NZEFA once again highlights on the main façade of the museum a mask called «Katso mask» or «Batcham mask». This mask is generally used in secret societies and its presence on the façade is a sign of celebration of this object. Slavery is a historical phenomenon common not only to the Bamendjinda people, but to Cameroonians, Africans, and many others. It is our past, our history, our heritage, our future. This museum is the embodiment of the memory and cultural vitality of the Bamendjinda people. Heritage case of the Bapa chiefdom, rock village The permanent exhibition of this museum has 7 spaces related to the central theme: «MAN, NATURE AND BELIEFS». The spaces defined by the Bapa traditional chief, SM David SIMEU, are the following: Discovering: which presents the history and relations between Bapa and the neighboring villages, and the organization of the chieftaincy and the place of the secret societies; Soak up: presents the nature and physical geography of Bapa; Create and build, presents the different poles of activity found in Bapa, as well as the evolution of architecture, from bamboo constructions with interpretations of weavings, to earthen brick construction and spouted earth; Savor, highlights the gastronomy of the 4 cultural areas of Cameroon, the methods of conservation of traditional foods and the food prohibitions of the past and present; Warrior, presents the power to heal as well as the place of totemic animals in the Bapa culture; To think, invites us to reflect on the protection of the environment with a nod to CIPCRE, and also unveils the modified model of the Bapa chiefdom; Blending in, displays nature, the medicinal and edible plants that nature offers us, with a miniature map of the Bapa village, and the tchui waterfall. This museum is marked by its picturesque architecture, which values the conical roofs of the West, the stabilized earth brick and especially its entrance in the shape of a cave which calls upon the various caves and rocks found in the locality and its surroundings. The scenography here highlights the local know-how in a process of transformation of vegetable waste. Thus, the work carried out by the architects of the DRC with the craftsman Banana Fashon led to the innovation of wall coverings from: dried banana leaves, peanut shells, dried corn leaves, colored woven straws...These decorations extend the understanding of the theme of the exhibition which is to bring man closer to nature. In addition to the need to highlight the know-how and beauty of the Bapa culture, to perpetuate it for the education and edification of future generations are the main motivations of the chief. Drawing inspiration from traditional architecture in order to create the architecture of tomorrow is a guarantee of safeguarding and promoting traditional know-how. The Route des Chefferies, through a creative scenography of the territory, proposes a reinterpretation of the great architectural principles without denigrating them. It uses symbols, materials, and traditional elements to give a new vision of the territory. The Route des chefferies is currently working on new concepts within the framework of the Route des Seigneurs de la forêt, Route de l’eau and Route du sahel programs. Previous Next

< Back La cartographie sensible, un outil puissant de participation citoyenne - récit d'un cours à l'EAMAU Quentin Lefèvre Si les projets de smart cities techno-centrés sont moins d'actualité dans l'agenda mondial, l'urbanisme est une discipline née au XXème siècle qui gagne à se réinventer en prenant plus en compte les besoins et envies réelles des habitant.e.s des territoires concernés. Les villes africaines caractérisées par leurs fortes croissances urbaines plus ou moins planifiées, peuvent mettre à profit l'intelligence et l'expertise d'usage de leurs habitants et promouvoir une action publique harmonieuse et efficiente. La clé pour ce faire réside justement dans une connaissance fine du terrain, des pratiques et surtout des représentations mentales des usagers de la ville concernée puisque ce sont bien les représentations qui guident l'action des uns et des autres. C'est là qu'intervient la cartographie sensible, un outil puissant qui donne la parole aux habitant.e.s pour mieux connaître leurs attachements, ce qui est important pour eux et finalement la valeur qu'ils donnent aux éléments constituant leur milieu de vie. La cartographie sensible améliore la prise de décision urbaine en intégrant les perceptions et les émotions des habitants dans les processus de planification de la ville. L'action publique moderne est souvent guidée par une approche technicienne, quantitative et parfois hors-sol, il peut être utile de revenir à une approche plus participative et centrée sur les usages, perceptions et représentations des personnes concernées. Ainsi, que ce soit à l'échelle d'un bâtiment, d'un quartier ou d'une mégalopole, les décideurs peuvent choisir de prendre des décisions basées sur les ressentis et les idées de leurs administrés. En complément des diagnostics techniques traditionnels, la cartographie sensible propose une nouvelle approche de la participation citoyenne. Il s'agit de prendre en compte et de documenter l'espace urbain tel qu'il est vécu et perçu par ses habitants ou usagers. Cet outil innovant et efficace se développe sur tous les continents depuis plusieurs années et rejoint les pratiques avancées de participation citoyenne, de community empowerment et plus largement d'urbanisme communautaire ou culturel. La cartographie sensible (aussi appelée cartographie subjective) se définit comme "la création de médias permettant de restituer l'expérience du territoire", c'est à dire que ce n'est pas tant l'espace physique qui va nous intéresser en tant que tel mais bien le ressenti, les émotions, les représentations et finalement la valeur que gens accordent aux lieux qu'ils pratiquent ou connaissent. Carte sensible participative du quartier Saint-Jacques à Besançon, Q. LEFEVRE, 2021 Par exemple, une communauté locale peut accorder une grande importante à élément vivant (un arbre par exemple) qui ne pourrait être décelée à la simple la lecture dans un bureau d'un plan technique de la ville. Comment procéder ? Pour savoir ce que les gens pensent (et veulent), le mieux est encore de leur demander. Ainsi dans un premier temps il s'agit de récolter les données pendant une phase de terrain pouvant aller d'une semaine à plusieurs mois. Pendant cette immersion, l'équipe projet va s'entretenir avec les parties prenantes (habitants, experts, élus), soit de manière spontanée en faisant des entretiens au hasard des rencontres dans la rue, les marchés, les commerces, soit de manière plus organisés d'ateliers dédiés. Il est important de veiller à la représentativité des personnes qui seront interrogées, donc à la diversité du panel, que ce soit en termes d'âge (les enfants ou les anciens n'auront pas la même perception de la ville), de genre (femmes et hommes ne vivent pas l'espace public de la même manière), de classes sociales ou de communautés. A l'inverse, il est aussi possible de choisir de se focaliser sur des groupes plus vulnérables (par exemple les femmes, les enfants, les personnes âgées ou en situation de handicap), afin d'envisager des politiques publiques spécifiques.Les questions qui peuvent être posées aux habitants sont par exemple : "Quels sont les repères de la ville (ou du quartier) d'après vous ?", "Quels sont les lieux que vous aimez, et pourquoi ?", "Quels sont les lieux que vous n'aimez pas, et pourquoi ?", ou encore "Qu'est ce qui constitue le patrimoine de la ville d'après vous ?"... Des outils numériques peuvent être utilisés pour la récolte des données, que ce soit via des applications dédiées ou simplement des questionnaires en ligne. Pour la mise en forme des données, le numérique peut aussi être utilisé par exemple pour créer des cartes interactives enrichies de médias (par exemple des photos ou des textes générés par les habitant.e.s). Maquette montrant les lieux repères (en bleu) aimés (en orange) mal-aimés (en rose) et considérés comme patrimoniaux par les habitant.e.s (en vert) Néanmoins une attention particulière devra être portée à l'accessibilité de tels outils. A la suite de cette phase de terrain, les données récoltées seront mises au propre, ordonnées et traitées statistiquement puis analysées avant d'être mise en forme de diverses manières possibles, que ce soit sous forme de cartes sensibles, de maquettes ou encore de formats audio type podcasts. Les cartes sensibles produites peuvent être imprimées et distribuées aux communautés locales et aux personnes qui ont participé aux ateliers. Elles vont alimenter un diagnostic sensible (complémentaire d'un diagnostic technique) qui aidera les urbanistes, les architectes et les élus à mieux comprendre comment la population vit et ressent la ville. Un atelier de cartographie sensible et communautaire à l'EAMAU de Lomé a permis aux étudiants d’exprimer et d’analyser leurs perceptions des espaces urbains. Au mois de janvier 2024, nous sommes intervenus auprès des étudiants en Master 1 à l'Ecole Africaine des Métiers de l'Architecture et de l'Urbanisme (EAMAU) de Lomé, lors d'un cours-atelier sur la cartographie sensible du territoire. Dans un premiers temps, la notion a été discutée, de manière théorique et pratique, illustrées par une présentation de cas d'étude déjà réalisés. L'intérêt des étudiants pour une telle pratique était manifeste, et elle rejoignait la manière de faire et de penser enseignée à l'école. Présentation de la carte sensible participative de la ville d_Abibjan EAMAU 2024 A la suite de cette discussion les étudiants ont pu s'initier à la cartographie sensible lors d'un atelier de pratique. Comme l'école accueille des étudiants venant de toute la sous-région, les élèves ont pu être regroupés par nationalités et travailler sur une ville de leur choix de leur pays d'origine. Ainsi, nous avons eu des cartes d'Abidjan, Bamako, Bangui, Lomé, Ouagadougou, Yamoussoukro et Yaoundé. S'agissant ici d'un travail en salle, les étudiants ont travaillé sur leur propre perception de la ville concernée. Dans un premier temps il ont dessiné (à la main sur une grande feuille blanche) la structure de la ville concernée (routes, places, ponts, parcs...) puis le travail de cartographie sensible a commencé en inventoriant et en localisant sur la carte 1/ les repères de la ville 2/ les lieux aimés 3/ les lieux mal-aimés 4/ le patrimoine de la ville. Concernant les lieux aimés ou mal-aimés, il est intéressant de noter que souvent, la perception de certains quartiers varie en fonction du niveau de fréquentation et de connaissance de celui-ci. Ainsi il est arrivé à plusieurs reprises qu'un même quartier soit aimé par une étudiante et mal-aimé par un autre membre du groupe car celui-ci le connaissait moins bien. Enfin les groupes ont présenté leurs productions à l'ensemble de la classe et des enseignants présents. Comme souvent lors de cet exercice la motivation et l'envie était forte car il est finalement assez rare (même pour des étudiants en urbanisme ou en architecture) de pouvoir légitimement partager son ressenti et sa perception de l'espace urbain. Il paraît important que les futurs techniciens, professionnels, experts et peut-être fonctionnaires et décideurs de collectivités locales sachent comment faire pour récolter et organiser les données relatives aux perceptions des habitants car avant d'être un objet d'étude intellectuel, la ville est avant tout un espace vécu avec son corps et ses sens. A l'heure de la (re)valorisation du patrimoine culturel des sociétés et villes africaines, l'approche participative promue par la cartographie sensible semble d'autant plus intéressante et porteuse d'un potentiel d'émancipation et de renouvellement des représentations de soi et de son territoire de vie.
