Applying remote sensing techniques to monitor green areas in Tashkent Uzbekistan

Abstract

Land use and land cover (LULC) change are one of the most important signals of regional environmental monitoring and study. Recently, the pull of capital cities has snowballed, an increasing number of people moving to the cities, especially in developing countries. Consequently, as more people arrive at cities, the more pressure will be on land. Land price getting high and constructions try using open green areas. A wide variety of green areas of different sizes will be solve many urban diseases and ecological problems at the same time improve the quality and life of urban residents, as urban green area provides various ecosystem services. The green area includes parks, woodlands, nature reserves and bare lands. With the population increase and expansion of cities, an increasing amount of open area, woodland and bare land has been converted into construction land, buildings due to the increasing demands and residential land. For the accuracy assessment, we applied an automatically supervised classification using the software QGIS 3.18. The reference values were based on ground truth data and visual interpretation.

Development of a method for determining the optimal areas for alternative energy facilities based on GIS technologies

“…Based on the results of the analysis, recommendations were developed for choosing the optimal area for the construction of alternative energy facilities. [1] In order to analyze the alternative energy resources in the software belonging to the family of geographic information systems, the authors first studied the geographical location of a total of 80 existing hydrometeorological stations in the country (Table 1) [2].…”

“…It is acknowledged that in the future it is necessary to use energy sources in ensuring environmental, economic, and energy security, and development of the energy sector of Uzbekistan [1,2]. Certainly, the development of renewable and alternative energy sources by protecting the environment while conserving natural resources is essential for the lives of future generations.…”

Improving the methods of determining the amount of non-agricultural land use in agriculturae in Uzbekistan

“…In 2019, 541 economic entities identified cases of land irregularities on an area of 2.1 thousand hectares, and 458 land-user entities identified appropriate measures. Here 71 cases of anonymity or misrepresentation of information from the report by users of land 23 percent, 184 cases of withdrawal from the projects of Economic Internal land formation by users of land 56 percent, 135 cases of non-economic or inefficient use of land by users of land 14 percent, 151 cases of violation of the law by users of land [22][23][24][25]. According to the analysis carried out, in the use of agricultural land in land violations, it is possible to observe the use of it for other purposes than its intended purpose, including the placement of crops other than the specified type of crop, as well as the cases of deviations from the terms of the contract.…”

Innovative technologies to increase the fertility of irrigated soils and crop yield

“…In Uzbekistan, various types of waste accumulate in huge quantities: industrial and agricultural waste, urban waste, fresh water ooze, sawdust, fallen leaves, etc. [17][18][19][20][21][22]. These wastes in their composition contain all the nutrients necessary for plants (Table 1).…”

“…Non-traditional fertilizers are important local fertilizers produced by the decomposition of various organic wastes by microorganisms. Non-traditional fertilizers applied to soil form optimal conditions for the growth and development of plants [5,19,21,22].…”
