The distinctive features of estuary irrigation, the current state and characteristics of estuary irrigation systems in the agricultural zones of Yakutia are given. On the example of typical estuary irrigation systems located in the Lena–Aldan and Leno–Vilyui interfluves, the regime of estuary irrigation in a changing climate is considered. It has been established that in the areas of estuary irrigation of Yakutia over the past 50 years, there has been an increase in the average annual temperature of atmospheric air from 1.5 to 3 ℃, which led to an increase in the sum of temperatures of the growing season over the past 8 years by 160 ℃ in the Lena–Aldan and Lena–Vilyui interfluves and date of commencement of irrigation of estuary meadows for earlier dates up to 5 days. An analysis of the amount of precipitation during the growing season shows a decrease in the amount of precipitation over the past 8 years from 90 mm to 80 mm in the Khorobutskaya FIS, located in the Lena–Aldan interfluve, and an increase from 96 mm to 120 mm on average in the Orosun–Negodyakh FIS, located in Leno - Vilyui interfluve. The yield for 2014-2021 in the Orosun-Negodyakh FIS increased comparatively by an average of 2 centners per hectare, while in the Khorobutskaya FIS, on the contrary, it decreased by an average of 3 centners per hectare. Studies on reclamation systems show the closest dependence of productivity on the sum of atmospheric temperatures and precipitation in the Orosun-Negodyakhskaya FIS, in the Khorobutskaya FIS on the total precipitation. In general, the conducted studies show the impact of climate change on the irrigation regime of estuary irrigation systems located in various agricultural zones of Yakutia and the need for their revision.

In the Republic of Kazakhstan, as well as in many countries located in the arid zone, ag-riculture is fundamental in economic development. Increasing water deficit requires reduction of water consumption in irrigated agriculture through introduction of technologies providing optimal conditions for growth and development of agricultural crops. Drip irrigation and sprinkling are promising technologies for optimizing the conditions for plant development. Drip-sprinkler irrigation technology is aimed at increasing of irrigation water use effi-ciency under the main drip irrigation method and during high air temperatures (more than 25oC) to improve micro- and phytoclimate parameters in the period of additional sprinkling irrigation. Impulse sprinkling improves the microclimate in the apple-trees development environment, water regime indicators of plants within day time in comparison with periodical regular sprinkling and increases the productivity of apple-trees.

The regional temperature increase observed in recent decades has led to a noticeable increase in the amount of atmospheric precipitation, as well as to an increase in the water content of small rivers. As a result of these phenomena, changes in the engineering and geocryological conditions of the foundations of hydraulic structures occurred, cryogenic processes in the water areas of reservoirs became more active, which significantly reduced the stability of irrigation and drainage facilities. On the example of a typical low-pressure hydroelectric complex of the Zarechnaya group of Yakutia, the possibility of improving the design solutions of existing irrigation and drainage facilities based on the substantiation and development of measures to increase water availability in a changing climate is considered. The analysis of the data obtained in the course of the study confirms that due to the warming of the climate observed in recent years, there have been changes that negatively affect the stability of the frozen foundations of irrigation and drainage facilities, in particular, an increase in the layer of seasonal thawing of permafrost soils and an increase in the water content of small rivers exceeding the established initial carrying capacity. structures. In order to increase water availability in a changing climate, additional measures have been justified and introduced to improve the design solutions of the existing hydraulic structure, which consist in increasing the throughput of the structure and improving anti-seepage, heat-insulating and anti-heaving measures.

The development and organization of hydro-reclamation systems is the process of transformation and interaction of its forming subsystems and blocks, the ability to realize agricultural and social potential for the transition to a higher rank of organization and orderliness, the ability to achieve a state of self-organization with maximum equipment with functional complexes for auto-mating processes and effects. These features correspond to the transition of hydro-reclamation systems to the highest level – the fifth generation. The economic function of hydro-reclamation systems of a high rank of organization is to provide comprehensive services to improve the unfavorable natural conditions of the territory in order to successfully develop various sectors of the national economy, primarily agricultural nature management. The production functions of hydro-reclamation systems of a high level of organization are realized through the sequential execution of engineering-reclamation technologies, the effectiveness of which depends on the information and resource security of connections between individual elements of blocks and subsystems. The article was made with support of the Ministry of Science and Higher Education of the Russian Federation in accordance with agreement № 075-15-2020-905 date November 16, 2020 on providing a grant in the form of subsidies from the Federal budget of Russian Federation.

Increasing the competitiveness of the modern domestic agro-industrial complex through the use of effective organizational and economic tools is one of the priority tasks of import substitution in the Russian Federation. An object. The object of research is the regulatory aspects governing activities in the field of land reclamation and agriculture. Goal. The aim of the study is to analyze the issues of optimizing the distribution of power in terms of the creation of reclamation parks, regulation of land legal relations, the formation of a system of preferences that stimulate agricultural producers to participate in reclamation parks. Materials and methods. The authors used the current legislation of the Russian Federation, as well as the concept of creating innovative infrastructure facilities for reclamation of the federal level, developed by modern scientists-ameliorators. Results and conclusions. The analysis performed allows us to say that the powers of the authorities of the Russian Federation at various levels are sufficient to create agromeliorative parks (hereinafter - APM). According to the authors, in order to carry out organizational and managerial functions, it is necessary to establish a single state management company - the AMP operator, directly subordinate to the Ministry of Agriculture of the Russian Federation. The AMP operator organization, among other things, should have the right to initiate in a judicial proceeding the alienation of a land plot of an unscrupulous agricultural producer in favor of the state in the event of a systematic violation of the established mode of operation of the reclaimed. The formation of special economic zones on the territory of the Russian Federation in the form of APM will create the preconditions for the formation of not only positive, but also negative socio-economic consequences. It is advisable to minimize the risks of negative effects by developing and adopting a framework federal law detailing the mechanism for the creation, functioning, and liquidation of AMPs, describing the rights and powers of AMP residents, participants, state bodies of the Russian Federation, constituent entities of the Russian Federation in terms of AMP management.

This article presents materials on the creation of a model of water intakes in a semi-limited reservoir in order to study the regularities of failures of an open collector-drainage network, as well as the impact of a decrease in their performance on the reclamation state of irrigated lands, taking into account the regulation of the reclamation regime of the soils of the Shuruzyak collector in the Syrdarya region. The authors consider a single well and a group of interacting wells located in any way, as well as a linear row of wells, of a very significant length near the Shuruzyak collector. The performed calculation shows an estimate of the balance with the identification of individual constituent sources, which ensure the flow rate of wells, which is most reliably produced by constructing filtration grids (graphically or based on modeling) using the method of adding currents. When calculating onshore water intakes in all the considered schemes, including those where the water intake is provided entirely by the inflow of groundwater from the coastline, the effect of an open collector must be taken into account. A decrease in the level under the action of pumping out of wells in such conditions should theoretically occur at all points of the formation, not only in the “capture zone”, limited by the neutral streamline, but also outside it, up to the collector.
