Alongside associated forms of socially and politically conscious food production, community food growing is routinely connected to a wide range of social and environmental benefits. However, robust evidence in support of these associations remains scant, and while the conversation has shifted in recent years to take account of the sometimes unintended or negative aspects of these activities, no consensus has been reached about how such forms of food growing should adapt to new conditions, or be scaled up to maximize their positive impacts. A July 2016 conference was organized to address this strategic shortfall. This themed issue presents the papers resulting from the conference.
