Water Scarcity and the Role of Storage in Development
Of the four major ways of storing water –in the soil profile, in underground aquifers, in small reservoirs, and in large reservoirs behind dams–the first is possible only for relatively short periods of time. In this paper, the authors concentrate on the three kinds of long-term technologies, and compare the hydrological, operational, economic and environmental aspects of each.
Water Scarcity and the Role of Storage in Development
By 2025, one-third of the population of the development world will face severe water shortages (Seckler et al. 1998). Yet, even in many water-acarce regions, large amounts of water annually flood out to the sea. Some of this floodwater is is committed flow to flush salt and other harmful products out of the system and to maintain the ecological aspects of estuaries and coastal areas (Molden 1997). However, in many cases, the floodwater is not fully utilized; and, of course, the floods themselves can do a great deal of harm.

Water and Development is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Water is perhaps the most critical natural resource upon which humans depend. Agricultural and food production, trade and ultimately the economic development of all regions of the world depend on rivers, streams, dams, oceans and other water resources. This critical relationship has persisted through the agricultural and industrial revolution and into the era of economic globalization. The relationship between human activity and the water resources on which it depends also continues to be reciprocal. Human consumption, energy, agricultural, industrial and other economic activity have significant impacts on water quality and quantity for better or worse. A key element of sustainable development rests on our global capacity to interact with the water resources on which we depend in ways that preserve them for our use and that of future generations. The two volumes on the subject present some of the topics such as Water, Agriculture and Food Interactions, dams, water valuation, arid regions, water-management, and Conflict over Water Resources, Water and Sustainable Development: They consider the implications which contributions have in each of these areas as well as introduce additional issues relating to the future of dams, innovative ways of increasing water supply, transboundary water resources, and the implications of global climate change for water resources. These two volumes are aimed at the following five major target audiences: University and College students, Educators, Professional practitioners, Research personnel and Policy analysts, Managers, and Decision makers and NGOs
