Abstract: Food security is at risk from climate change. In fact, climate change and its drivers already affect food production through increased temperatures, changed precipitation patterns, extreme event frequency, and escalated carbon dioxide (CO2) and ozone. These effects are expected to continue for the foreseeable future. This will cause changes to agricultural production worldwide with regional consequences for global food security. In the face of this, adaptations must be pursued that help agriculture maintain and enhance productivity under climate change while meeting growing demands for food. This chapter reviews the current literature on the impacts of climate change on agriculture and possible adaptation strategies to combat its effects. Specifically, this chapter focuses on research conducted on crop systems, livestock, fisheries, and food access. This study concluded that food production systems around the world will be altered unevenly by climate change, with some gaining and many losing. Possible adaptation strategies will be suggested and successful implementation will need to include both public and private actions. Given the inevitability of climate change impacting agricultural systems, adapting to the impacts is necessary to maintain future food security. More research is encouraged to determine how to best incorporate multiple systems, actors, and interests in adaptation, as well as how to best respond to the imminent threat to the food system.
