The practise of UPA (Urban and Peri-urban Agriculture) is central to FAO’s (Food and Agriculture Organisation of the United Nations) current mission in support of the transformation to more efficient, inclusive, resilient and sustainable agrifood systems, through mainstreaming green innovation and digitalization under four betters–Better Production, Better Nutrition, a Better Environment and a Better Life. In addition, UPA is critical to the operationalization of linkages between the Sustainable Development Goals. This sourcebook serves as a reference to provide guidance and recommendations when planning and implementing UPA interventions. Target readers include local decision-makers, policy advisors, urban planners, and others involved in the design and implementation of production systems strategies and policies.
