With most of the world population living in cities, there is an increasing complexity that is accompanying this process. In addition to the growing number of agents interfering in the planning process and in cities evolution, it is important to note that until today urban policy fails to understand its dynamics. Complexity sciences offers an open system methodology to approach urban systems.

With growing urbanisation trends, cities are facing numerous challenges and are the most vulnerable to climate change. In order to promote sustainable cities and communities it is important to adopt a holistic and integrated approach. The Urban Nexus, which is a relatively recent concept, is an approach to sustainability that seeks to integrate sectors and silos in the design and development process. This paper will look at cities which have already adopted this approach and show the benefits of adopting such an approach.

Urban and peri-urban agriculture (UPA) is widely distributed throughout the Global South. Despite urban population growth and diversifying food habits, UPA delivers an important part of urban food supply, as well as other types of services to cities, such as employment and waste reuse. Nevertheless, the extent and importance of UPA varies between different urban areas, while challenges like limited recognition, land conversion, and water pollution and competition threaten the potential of UPA to contribute to urban resilience.

Cette contribution analyse les interactions entre les politiques d’aménagement du foncier sur la commune de Cotonou (Bénin) – particulièrement les opérations dites de lotissement et de remembrement –, et l’exposition importante de celle-ci aux contraintes environnementales, en particulier les inondations.
