Water Supply and Scarcity

According to the United Nations, water scarcity is defined as the point at which the aggregate impact of all users impinges on the supply or quality of water. Water scarcity is a relative concept and can occur at any level of supply or demand. Scarcity may be socially-constructed or the consequence of altered supply patterns stemming from climate change. Resources available in this sub-theme include U.S. drought monitoring data, workshops for rural water supply systems, among other resources that support water supply and scarcity.

U.S. Agency for International Development
In arid regions like the experimental basin of the Sanzar river in Uzbekistan the agricultural activity is restricted by the small amount of river water. At the same time there are sufficient rain water resources during spring which can be harvested, stored in soil and used by plants during the dry...Read more

Estimating Productivity of Water At Different Spatial Scales Using Simulation Modeling

Published: 
January 1, 2001
U.S. Agency for International Development
Implementing real water saving measures in irrigated agriculture is only possible if all the components of the current water balance are clearly understood. Although measurement of all these components is infeasible on a spatial and temporal scale, hydrological simulation models can fill the gap...Read more
