The public health sector must address the dietary changes brought about by urbanization and the unsanitary conditions in poor urban areas. Policies to promote child health have to focus on the greater time urban mothers spend working away from home. The most effective, relevant policies to treat these and other issues must connect the needs of the poor to a politically responsive local government that has the technical and institutional capacity to act. Whereas most rural interventions to increase well-being aim at agriculture in some way, urban interventions must address a broader range of sectors and actors. Only holistically conceived responses that coordinate actions across sectors, public and private actors, and household, community, national, and global levels can lead to sustainable urban food and nutrition security in the future.
