Urban agriculture has become a popular topic for metropolitan areas to engage in on a program and policy level. It is touted as a means of promoting public health and economic development, building social capital, and repurposing unused land. Food policy councils and other groups that seek to position urban agriculture to policy makers often struggle with how to frame the benefits of and potential problems with urban agriculture. In some cases, the enthusiasm is ahead of the evidence. This review provides an overview of the documented sociocultural, health, environmental, and economic development outcomes of urban agriculture. Demonstrated and potential benefits, as well as risks and limitations, of this growing field will be discussed. We also offer recommendations for further research to strengthen the scholarship on urban agriculture.
