Present World Situation Concerning Water and Agriculture Output
The supply of water for drinking and industrial purposes and for irrigation is becoming one of the more critical problems in the world and especially in developing countries. It is a topic...
The U.S. Agency for International Development's Water and Sanitation for Health (WASH) Project: Lessons of the Decade
A review of the International Decade of Water Supply and Sanitation of the 1980's shows the enormous accomplishments made to date: 600 million more people served with a drinkable...
The International Drinking Water Supply and Sanitation Decade and Beyond
The International Drinking Water Supply and Sanitation Decade ends in 1990. Though the Decade has not achieved its numerical objective of universal access to water and sanitation, it has...
Lessons Learned in Southeast United States
The droughts during the decades of the eighties in the southeast were the most severe during the period of record. In addition to the immediate inconvenience they caused, they were precursors...
Great Lakes Waters: Too Little or Too Much?
Water supplies in the Great Lakes Basin, the world's largest fresh water supply, are more than adequate to meet current and projected needs. However, supplies could become...
Corps of Engineers Drought Management Experiences
The drought of 1988-89 was one of the most severe on record for many regions of the United States. Its severity can be measured in terms of the areal extent of hydrologic impact, the record...
