Food Cops under Global Warming and Changing Water Availability
- Resumen
- Much of food availability in the world depends on rain-fed crops, thus present and future changes in the water cycle (e.g. total amount, annual distribution and intensity of precipitation) may play a fundamental role in global food security. In particular, projecting further changes include increasing in temperature and changes in precipitation, with decreases in some dry regions at mid-latitudes and in the dry tropics (e.g., the Mediterranean basin, western USA, southern Africa and north-eastern Brazil) that may intensify present limited water resources. Moreover, increases in the frequency and severity of heavy precipitation and extreme drought events are expected during the 21st century. Finally, sea-level rise is projected to extend areas of salinisation of groundwater and estuaries, resulting in a decrease of water availability for irrigation in coastal areas. All these projections, together with other external factors (increases in food demand, changes in human diet, etc.) may determine important impacts on food crops productions and the following food availability. This work aim to present a complete overview of the impacts that globalwarmingand changingwater availability willhaveonfoodcropsandthe adaptationstrategiesthatmay beusedtocopewiththese.
