Developing countries are urbanising rapidly. Many urban dwellers are poor and have to deal with malnutrition and limited access to healthy food. How can their food security be improved? And how can the city and the surrounding agricultural countryside be better connected so that farmers around cities can benefit as much as possible from the growing demand for food in the cities? Strategic interventions and practical solutions are needed, with full engagement of local actors, to ensure food security in both urban and rural communities improves. Changing demands in urban areas impact rural areas choices of investments and production.
