Highlights
17.08.05 Seminar on issues of rational use of water and land resources, reduction of harmful influence of wastes on environment was held in Scientific-research institute of water supply, canalisation, hydraulic construction and engineering hydrogeology.
Reduction of harmful influence on the nature, stabilisation of ecologic situation is one of the most important directions of ecological policy pursued in Uzbekistan.
The Law On wastes and the action plan on preservation of environment for 1999-2005 envisage priority tasks to be solved in this regard. State Nature Protection Committee and its structural divisions are working on implementation of these tasks.
During the seminar, scientists, specialists, representatives of nature protection committees analysed the work on stabilisation of ecological situation in the country, discussed the available positive experience. Participants developed measures on implementation of tasks set in the new normative documents concerning protection of nature. Read more http://www.caresd.net/site.html?en=1&id=902

Background
Overview of Water Resources
Water Resources
Water management may be the single most important issue for Uzbekistan. Forty years of poor management now threaten agriculture, soil quality and availability of water for all purposes. The Government faces difficult political choices. Cotton, a significant foreign-exchange earner, consumes more water in irrigation than can be sustained. (See Chapter 10.) Salinity of soil, surface water and groundwater is increasing to unacceptable levels. Run-off from irrigation is negatively affecting the quality of drinking water from the main water streams. Water is becoming scarce for all purposes.
The main sources of water resources are: the AmuDarya with average long-term withdrawal 2,500 mІ/s, the Syr Darya (1,200 mІ/s), the Zeravshan (164 mІ/s), the Kashkadarya (50 mІ/s), the Surhandarya (52 mІ/s), the Ahangaran (23 mІ/s), the Chirchik (22 mІ/s).
The AmuDarya has the largest drainage basin, covering 227 thousand kmІ in the mountain region only, with a water volume of 78 kmі per year (average long-term index, stretch - 1,440 km). The SyrDarya with a water collecting area of 150 thousand kmІ, 2 times less in water volume (36 kmі per year) but it exceeds in stretch (2,140 km).
Discharges of the both rivers are formed in contiguous countries - Kyrgyzstan and Tajikistan. Annual discharge, formed within the republic, makes up 9% of the total water resources being used for needs of national economy.
Forecasting supply of ground water is 19 kmі per year. Over 50% is used as a reliable source of drinking water for population, industrial needs, pasture watering and land irrigation.
Transboundary rivers of the region are impacted by pollution of cattle-breeding, domestic, municipal, industrial sewage and collecting, drainage waters. Polluted sewage from more than 5 thousand water using objects go into surface waterways and make up approximately 20% of total water withdrawal in open reservoirs.
There are two river basins in Uzbekistan that form the Aral Sea basin. In addition to this, there are 94 major aquifers, and sporadic rainfall that is unevenly distributed, occurring mainly in the mountainous regions during the winter months. The water resources that are available are in short supply in much of Uzbekistan.
Water in Uzbekistan's Economy
In 1994, the agricultural sector contributed some 36 percent to GDP. In 1996, it employed about 33 percent of the total economically active population. The contribution of crop production to GDP was about 20 percent from irrigated crops and 2 percent from rain-fed crops. Cotton, called 'white gold' in Uzbekistan, vegetables and fruits are the country's principal exports. Uzbekistan is one of the world's largest cotton exporters.
Irrigation in Uzbekistan started more than 2,500 years ago in the seven natural oases. At the beginning of the 20th century, about 1.2 million hectares were irrigated in Uzbekistan. Large-scale development started in the late 1950s, when the Soviet Union decided that Uzbekistan should specialize in the production of cotton. Modern irrigation techniques were then developed in the Hunger steppe in the central part of the country. By 1994, irrigation covered almost 4.3 million hectares, or about 82 percent of cultivated land.
Water Use and Management
During the Soviet period, the sharing of water resources among the five Central Asian republics was based on the master plans for water resources development in the Amu Darya (1987) and Syr Darya (1984) basins. In 1992, with the establishment of the Interstate Commission for Water Coordination, the newly independent republics decided to prepare a regional water strategy while continuing to respect existing principles until the adoption of a new water-sharing agreement in the new water strategy. The surface water resources allocated to Uzbekistan are calculated every year, depending on the climatic situation and existing flows.

National Policy Context
Lessons:
- The Samarkhand and Bukhara experience show that capturing water sources some 200-300 km away (Amu Darya) and transporting drinking water over long distances a) is un-coverable with water tariffs (=unaffordable) and b) has lead to secondary pollution IN the system (source: SDC study cited at Yerevan EUWI-EECCA meeting, Nov 05)
