Impact details: soil moisture change

impact chain for meteorological drought (click any node to view details):
The amount of water stored in the ground or at the land surface is defined as soil moisture. Soil moisture levels are determined by a complex interplay among precipitation, evaporation, run-off and soil drainage. They impact the distribution and growth of vegetation, soil aeration, soil microbial activity, erosion, the movement of nutrients and much more. Higher air temperatures, as a result of global warming, would increase the rate of evaporation and remove the moisture from soil faster than it can be added by precipitation. Hence, some regions are likely to become drier even though their rainfall increases simultaneously. Decreasing soil moisture affects human activities, particularly agriculture, dramatically.
