Agriculture

One of the major worries concerning climate change is the effect it will have on agriculture, both globally and regionally. The main question is whether the world can feed itself with an extra 2 billion people on the planet by 2050 and a rapidly changing climate. Figure 27 shows the drop in cereal grain yields that has already occurred. Modelling suggests that in higher latitudes agricultural productivity may increase due to the longer growing season and reduced frost damage—but some of this will be offset by more frequent crop damage due to extreme weather events. Agriculture production will however reduce significantly in the tropics and sub-tropics due to much hotter temperatures and more variable rainfall.
