Climate change poses significant threats to our food system and resource stability and has the potential to aggravate existing social inequities in the agrifood system. This research addresses how issues and approaches in food system equity can be applied to food system planning to address the aggravation of social inequities by climate change. To do this, this thesis asks, how can interventions to advance food system equity be applied to planning initiatives so that inequities are not reproduced or exacerbated in the face of climate change? Key issues and approaches in food system equity are identified through a review of literature and examined through critical inquiry to evaluate their capacity to mitigate the aggravation or reproduction of inequities by climate change. Based on this analysis, a series of recommendations are made to food system planners for improving equity among producers and consumers in the food system. These recommendations are systematically reviewed through a food security framework in order to assess how mitigating inequities in the face of climate change may also improve food security. This research concludes that while there are significant opportunities for planners to promote equity in the face of climate change, food system and climate change planning fields remain largely disconnected and neither adequately address climate-driven threats to social equity.
