The productivity of crops and livestock may decline because of high temperatures and drought related stress. Regions of the world that now depend on rain fed agriculture may require irrigation, bringing higher costs and conflict over access to water. The shift in seasonal rainfall patterns and more severe precipitation events and related flooding may delay planting and harvesting.Prime growing temperatures may shift to higher latitudes, where soil and nutrients may not be as suitable for producing crops, leaving lower-latitude areas less productive. Lastly Insect and plant pests may survive or even reproduce more often each year if cold winters no longer kill them off. New pests may also invade each region as temperature and humidity conditions change.
