Book excerpt: For a long time, urban agriculture initiatives have been explored and novel policy and planning practices have been investigated. With the global food crisis the role urban agriculture has to play becomes more and more urgent. The potentials are large: it brings social justice, it limits climate change, it provides a healthy urban condition, it stimulates biodiversity and gives disadvantaged people an economic opportunity. After 15 years in the making, the time is ripe to see whether the growing of food has established a prominent position in urban planning and policies, food productivity, safety and security, social well-being, the arts, and human health. In this volume several aspects of growing food in the city are explored. Urban Agriculture plays a significant role in society. Nevertheless, it did not become a mainstream topic in day-to-day practice. This book provides concrete solutions and clues how to give urban food production a crucial role in the future planning of urban environments.
