Document Summary
What factors would lead to a species being vulnerable to climate change: threatened by other factors, loss of habitat. Crop yields are more negatively impacted in most tropical areas than at high latitudes. Average crop yields in africa and south asia may decline by 8% by the 2050s (due to climate change): crop impacts from climate change become more severe with increasing magnitude of global warming. Large parts of the world where crop yields are expected to decline coincide with countries that currently have a high burden of hunger.

Government has responded by installing desalinisation plants to provide water to. Long-term the trend will dominate no geopolitically secure water supply.
