This issue of the UA Magazine is a joint effort of the RUAF Foundation and the Centre for Agroecology Water and Resilience (CAWR). It aims to articulate and document the emerging field of urban agroecology. Definitions differ and tend to reflect the various ways the term agroecology is understood in different countries, by different organisations, or according to different political economic preferences. As usual, the Magazine shares a diversity of perspectives from a wide number of geographical contexts. The Magazine is organised in four blocks: 1) Conceptualising urban agroecology; 2) Practices and city initiatives; 3) Urban policies supporting agroecology; 4) Citizen and social movement-led initiatives.
