By John Ingram, Food Systems Programme Leader, Environmental Change Institute, on the 'Climate Change, Global Food Security, and the U.S. Food System' report to which he contributed:

It is well recognised that climate change poses considerable risks to global food production: IPCC AR5 and many other analyses detail where, by how much and to what types of production system given degrees of climate change will have impact. There are, however, fewer analyses of the challenges facing the food system as a whole. While disruptions to production are clearly important, climate change – and extreme weather in particular – will impact many of the food system’s ‘post-farm gate’ activities and hence food security; food security depends on more than just food production. For instance, damage to food transport and storage infrastructure due to storms and floods causes local shortages, affecting food affordability and variety. Temperature and humidity changes can lead to numerous food safety issues, and hence both health considerations and food waste, the later also affecting availability. Consumer behaviour can also change, leading to changes in diets and hence nutrition.
