In the face of climate and environmental change, the food sufficiency challenge is more than ever an important issue. This article provides an assessment of the food situation, how it has evolved in recent decades, and how it is likely to change in the future. We provide an overview of how climate and extreme weather events are predicted to change in the future, and summarize the estimated impact of these changes on agriculture. To do so, we first detail the different methods employed by climate change impact assessments, and discuss their strengths and weaknesses. We then review the findings from this literature and provide a range of predicted impacts on agriculture. This article also discusses how the food sector will be affected by climate change mitigation policies, such as clean-energy mandates, agriculture management improvements, carbon pricing, and carbon sequestration measures.
