When it comes to the effects of climate change we seem to be focused primarily on one aspect of it – lack of freshwater. There are other items to consider like the food that is produced using freshwater.
With droughts, flooding and variability in not only in seasonal rainfall but freezing temperatures we are seeing decreases in the production of food and fodder crops. Farmers don’t know what to plant when. It’s predicted that the average decrease will be about two percent per decade. This is a global conservative estimate with larger regional decreases forecast.
Many of the world’s major crops have been developed from selective breeding programs to fit into a specific region with a fixed periodicity of rainfall and temperature. Global production estimates are based environmental homeostasis.
The current UN panel on climate quarterly report deals with this issue.
