Project timeline<\/strong>: 4.01.2021-31.12.2023<\/p>\n\n\n\n

Expected results and their relevance: Uzbekistan is located in sharp-continental, hot and arid climate largely determine the distribution of water resources in mountainous and plain areas. The main consumer of water resources is the population living in the lowland part of the country. Whereas, the main catchment area, numerous rivers of the region are located in mountainous and high-altitude areas. Rivers are fed by meltwater from seasonal snow cover, glaciers, and rainwater. Climate change negatively affects the area of glaciation in the mountainous regions of Uzbekistan.<\/p>\n\n\n\n

Scientific research in the Republic has shown that water reserves in glaciers on the horizontal-glacial belt of mountains are sharply decreasing. This is a proof of the reduction of glaciation areas in the mountain systems of Tian Shan, Pamiro-Alai, etc. For example, according to published data, there were more than 8,000 glaciers in the territory of Tian Shan. The glaciation area was 7,3 thousand km2<\/sup>. The reserves of fresh water preserved in mountain glaciers were estimated at 650 billion m3<\/sup>. Over the period 1960-2005, about 100 glaciers disappeared from the Zailiysky Alatau (a mountain range in the northwest of the Tien Shan), the glaciation zone of the Western Tien Shan (the Pskem range) decreased by 16.8% over 20 years. There were more than 10,000 glaciers in the Pamir-Alai, covering an area of 9,820 km2<\/sup>.<\/p>\n\n\n\n

From 1957 to 2000, in just 43 years, water reserves in Pamiro-Alai glaciers decreased by more than 25% (according to other data, more than 1000 glaciers disappeared in Pamiro-Alai during the period 1960-2005). In general, during the period 1957-1980, the glaciers of the Aral Sea basin lost 115,5 km3<\/sup> of ice (approximately 104 km3<\/sup> of water), which is almost 20% of the ice reserves as of 1957.<\/p>\n\n\n\n

Due to the inaccessibility of high-altitude areas, there is no possibility of systematic direct observations of the state of glaciers. The most effective tool in studying the processes of the glaciers degradation of Uzbekistan is the use of remote sensing images and GIS technologies. Taking into account that all available information on glaciation in the studied regions of Uzbekistan includes data from the USSR Glaciers Catalogue as of 1957-1960, cartographic materials and glacier inventory data as of 1978-1980, 2000-2002, individual studies of 2010-2015 on analog satellite images, detailed research of the planned in this project are relevant.<\/p>\n\n\n\n
