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
Problem of Water Scheduling in West Pakistan, Research Studies and Needs
Published:
November 1, 1971U.S. Agency for International Development, Colorado State University
The capacity to build and maintain the irrigation system has exceeded the capacity to manage the allocation of water for maximum agricultural production. The irrigation system was not designed to supply total crop water needs plus leaching requirements, but rather to provide sufficient water during...Read more

Pakistan, South East AsiaMaximum Water Delivery in Irrigation
Published:
August 1, 1971U.S. Agency for International Development, Colorado State University
In order to increase the water delivery efficiency of an existing irrigation system, it is proposed that modern mathematical optimization techniques be applied to the management of irrigation water delivery. A deterministic mathematical model is developed to simulate the events that occur in...Read more
