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.
