In my talk, I discuss two ways of linking climate change, agriculture and human health. In each case, food consumption is the central element. First, climate change can impact agriculture through changes in yields, which in turn affects food consumption through changes in supply, and human health through changes in dietary risk factors. Second, changes in food consumption that are brought about by changes in food environments and incentives can impact agricultural production through changes in demand, which in turn affect agriculture’s impact on climate change. I illustrate each pathway with global modelling studies that connect environmental assessments with comparative risk analyses of non-communicable disease mortality.
