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.

Water Supply and Scarcity Resources

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

Alternate Wet/Dry Irrigation in Rice Cultivation: A Practical Way to Save Water and Control Malaria and Japanese Encephalitis

Published: 
January 1, 2001
U.S. Agency for International Development
Due to increasing scarcity of freshwater resources that are available for irrigated agriculture, in the future it will be necessary to produce more food with less water. More irrigated land is devoted to rice than any other crop. One method to save water in irrigated rice cultivation is the...Read more
