Book excerpt: This book presents the findings of a multidisciplinary study on the effects of urban agriculture (UA) on the social, economic and environmental aspects of the quality of life in Sofia - the capital of Bulgaria. The analyses are based on a sociological survey representative of 3 districts of Sofia (among 750 people), in-depth interviews, focus groups, expert statements, ecological monitoring of UA sites, and spatial mapping of natural resources for UA. It also focuses on UA effects on the social well-being of citizens and communities, the correlation between social capital and UA attitudes, the challenges for UA to integrate disadvantaged social groups, the factors for success of small UA businesses, as well as the role of policy and civil society in developing UA. This work is also important for the analysis of the underlying links between all aspects of urban agriculture, many of which are valid beyond the local socio-economic context and environmental specifics of the city of Sofia.
