"Urban agriculture is extensively established in cities of southern countries. Though often absent from land planning policies, it manages to exist and adapt to urban constraints. The integration of agriculture into urban life has often been studied from a political, economic or environmental angle. We focus on studying this integration in socio-spatial terms and three examples are developed here in order to highlight different integration modes that result from urban farmers’ practices: in Bobo-Dioulasso (Burkina Faso), farmers establish social relationships to ensure their access to productive resources; in Metro Manila (Philippines) the appropriation of practices and networks of actors at the local level is a guarantee for sustainability; and in Saint-Louis (Senegal), it is through forms of organization initiated by farmers that they are able to assert their interests with urban authorities."
