An excellent interactive map is available from the World Food Programme. It allows the viewer to create different outcomes based on how greenhouse gases are either controlled or increased in the future, and to what extent; that action, in turn, drives how food security will be affected by climate change. Here is the information from their website to link to the map:
Food Insecurity and Climate Change Vulnerability map
The Food Insecurity and Climate Change Vulnerability map, produced by the UN World Food Programme (WFP) and the Met Office Hadley Centre, illustrates how strong adaptation and mitigation efforts will prevent the worst impacts of climate change on hunger globally and help make people less vulnerable to food insecurity.
