Impact of Global Warming on Food Security: How does a 1°C increase in temperature affect levels of food insecurity?

BACKGROUND
Thinking of the drivers of food insecurity, one can easily imagine the impact of extreme weather events –droughts, natural disasters, and more – on a family’s ability to meet its food security needs. However, the gradual and incremental impact of global warming on food security might be less perceptible.

METHODOLOGY
Global warming is represented by an increase in the global average temperature, which in turn influences and alters the climate and which then in turn can influence each of the drivers of food insecurity. Modelling the interactions between complex patterns of climate, each of these drivers, and food insecurity would be extremely complex. Instead, the analysis looks at the link between local temperature change and local food insecurity directly.
