“…The present paper introduces the ecological environment crisis of the Aral Sea from the perspective of water volume, area, soil, land use, and salt dust in the area that emerged due to the retreating lake [38][39][40][41]. It focuses on the vegetation change and reconstruction in the whole Aral Sea basin and the retreat area [42][43][44]. The lake buffer zone is an important part of the lake ecosystem and a vital protective barrier.…”

A buffer zone can be used to analyze the influence of the lake on the surrounding spatial elements, which is of great significance for discussing the problems of lake retreat, vegetation degradation, and overall environmental deterioration in the Aral Sea. Taking the 3 km buffer zone of the Aral Sea as the research area, the spatiotemporal variation characteristics and main influencing factors of the Normalized Difference Vegetation Index (NDVI) in the Aral Sea research area were studied using remote sensing over 31 years (1987, 1997, 1992, 2007, 2010, 2014, 2015, 2017, and 2018). The results showed that the vegetation growth in the Aral Sea buffer zone deteriorates with the retreat of the lake; the vegetation of the small Aral Sea began to recover due to the stable water volume and salt content of the lake; vegetation began to grow in the west coast of the West Aral Sea; the shrinkage of the Aral Sea caused by human activities is an important factor affecting the growth of the vegetation. This study provides a reference for the restoration and reconstruction of regional vegetation.

Today in Uzbekistan, fines are imposed for sanctioning violations of agricultural lands, which are used irrationally in protecting agricultural lands and preventing them from escaping from agricultural turnover. The calculation of these fines is included in the category of administrative offenses and is punishable by fines. This is a very recurring violation of the use of agricultural land for purposes other than those intended for illegal use. The imposition of fines is not sufficient to determine the amount of the basic calculation in Uzbekistan, and it is not effective enough to protect them. In order to increase the effectiveness of sanctions, it is advisable to impose fines for the illegal use of agricultural land in the protection of agricultural lands, taking into account the size of the land, the soil fertility, and the yield that can be obtained from it. Because it significantly increases the amount of fines and allows you to direct these fines for the efficient use of these lands. Therefore, this article offers suggestions for improving the method of calculating the amount of fines for improper use of agricultural land, taking into account the size of the land, soil fertility, and productivity.

The article showed that the internal land development projects, which include the organization of the territory, along with other measures, will give certain positive results in the rational organization of the use of dry land. Land planning projects developed based on land assessment data create an opportunity to optimize areas of arid lands and crops and justify the economic and technical-organizational aspects of the effective organization of agricultural production in these areas. The results of the conducted scientific research confirmed that in organizing the use of dry arable land in the plain region, first, it is of great importance to search for water sources in these areas, including the study of underground water sources and to positively solve the issues of water extraction by digging artesian wells. Using the data of soil monitoring in dry areas, the soil's natural fertility, its production characteristics, and the possibilities of its use in agriculture were considered to organize the agriculture of the region. Special agrotechnology for soils in dry areas was proposed. In this case, the use of secondary resources available in the republic (low-grade phosphorite, non-traditional agro-ores, various wastes) in field conditions on low-productivity lands (credit score below 40); it was recommended to obtain new organ mineral fertilizers by applying biotechnological methods on farmlands. Organ mineral fertilizers are prepared by composting based on manure and low-grade coal phosphorites in a ratio of 9:1 for 4 months. Other organ mineral fertilizers are made because of Angren low-grade coal and Central Kyzyl-Kum phosphorite flour. These fertilizers have been tested in farm conditions. The use of the proposed technology is resource efficient and solves environmental problems. When applying this technology, soil fertility is restored and improved, the amount of organic matter and organic matter in it increases year by year, the cost of mineral fertilizers is 30-40% and more, and the cost of organic fertilizer is 3-4 times allows to reduce. According to the research results, an additional harvest of 10-12 s/h was obtained from winter wheat.
