Food security in a warming climate
Marshall Burke, Stanford University
I begin with a brief overview of what is meant by "food security'' and how this concept might be related to the climate system. Importantly, food security is a function of both the total amount of food produced as well as individuals' abilities to access this food and its nutrients,and climate could shape these different components in different ways. I then use evidence from the distant and recent past to understand how these different components of food security have responded to changes in climate, highlighting both the large amount that we now know as well as the glaring holes in our understanding that still remain. Finally, I discuss what this historical understanding implies for how expected future changes in climate could affect trends in global future food security. In the absence of substantial additional adaptation,future warming could have large negative consequences for food security.
