This paper offers a critical assessment of the value and utility of the evolving City Region Food Systems (CRFS) approach to improve our insights into flows of resources-food, waste, people, and knowledge-from rural to peri-urban to urban and back again, and the policies and process needed to enable sustainability. This paper reflects on (1) CRFS merits compared to other approaches; (2) the operational potential of applying the CRFS approach to existing projects through case analysis; (3) how to make the CRFS approach more robust and ways to further operationalize the approach; and (4) the potential for the CRFS approach to address complex challenges including integrated governance, territorial development, metabolic flows, and climate change. The paper begins with the rationale for CRFS as both a conceptual framework and an integrative operational approach, as it helps to build increasingly coherent transformational food systems. CRFS is differentiated from existing approaches to understand the context and gaps in theory and practice. We then explore the strength of CRFS through the conceptual building blocks of 'food systems' and 'city-regions' as appropriate, or not, to address pressing complex challenges. As both a multi-stakeholder, sustainability-building approach and process, CRFS provides a collective voice for food actors across scales and could provide coherence across jurisdictions, policies, and scales, including the Milan Urban Food Policy Pact, the Sustainable Development Goals, the Habitat III New Urban Agenda, and the Conference of the Parties (COP) 21. CRFS responds directly to calls in the literature to provide a conceptual and practical framing for policy through wide engagement across sectors that enables the co-construction of a relevant policy frame that can be enacted through sufficiently integrated policies and programs that achieve increasingly sustainable food systems.

SUMMARYThe current paper briefly summarizes the available evidence regarding the potential of urban agriculture to respond to a number of key urban challenges and reviews the perspectives on urban agriculture applied by local and national authorities. The last section of the paper briefly presents the authors’ views on the development of urban agriculture as an integral part of sustainable city development.

Abstract:In the context of growing urbanisation, urban poverty, and climate change impacts, the importance of urban food security and urban food systems is increasingly recognised by both local and national governments, as well as international actors. There is also a growing understanding that urban development and food systems cannot be decoupled from rural development given the multiple impacts that urban areas have on their surroundings. In recent years the concept of City Region Food Systems (CRFS) has emerged as a promising approach to support local governments, policy makers, and multi-stakeholder bodies in making informed decisions to improve urban and regional food system sustainability and resilience, while taking into account a more integrated approach to territorial development across urban and rural areas. This paper is based on an ongoing FAO and RUAF programme of assessing and planning City Region Food Systems, currently implemented in eight city regions in Canada, Colombia, Ecuador, Senegal, Sri Lanka, The Netherlands, and Zambia. The paper analyses the content, definition and delimitations of the concept of City Region Food Systems by presenting two case studies from Latin America (Quito and Medellín), and discusses first advances in policy uptake and territorial food planning.
