Increasing city resilience through urban agriculture: challenges and solutions in the global north

Cities, which now host the majority of the global population, are vulnerable to environmental and socio-economic disturbances, which are likely to increase in number and severity in the near future. Urban agriculture (UA) could help increase the resilience of cities to a range of pressures and acute shocks by improving food security and public health, building social capital, and promoting circular economies. However, comprehensive assessments of its potential are still lacking. Here, we use a systematic review of the literature on UA in the global North to identify factors that determine its success in providing resilience benefits, explore challenges that can limit this, and develop a conceptual model to highlight the ways in which it could be enhanced through research, policy, and practice. We define the success of UA in increasing city resilience as determined by five factors, which in turn depend on the amount of institutional and public support for UA, the presence of a sufficient knowledge base, communication and collaboration among different actors, and resourcefulness in finding alternative ways to use space and other resources efficiently. We close with a discussion of specific directions for research and practice based on the conceptual model developed here.
