This study aims to develop a methodology for determining and calculating the limit size of agricultural land plots that can be leased by individuals and legal entities of the Republic of Kazakhstan. The article substantiates agricultural production after the current long-term lease terms end. The basic condition is the formation of land use, in which there is a close dependence on conditions and factors of production, where land, material resources, and labour are in certain proportions and balanced. The main criteria for determining the limiting sizes of land are: land area, leased to a single entity should not exceed 1/3 of the area of farmland rural district specific administrative area, and the physical person no more than 15% of the area of agricultural enterprises of the same specialization. Emerging land uses should be subject to zonal specialization by natural and agricultural zoning; take into account the minimum thresholds for the area of crop rotation in the crop production sectors and the size of livestock in herds of different types of livestock by the breed composition in the livestock industry.

In Ukraine, intensive agricultural use involves a significant area of land with degraded and unproductive soils, which is economically impractical and ecologically dangerous. Part of the land was impacted by military activities. One of the tasks of sustainable development in Ukraine is to stop the process of land degradation, achieve a neutral level of land cover degradation, and promote the restoration of their productivity. This can be achieved by growing energy crops on degraded soils. Energy crops can grow on infertile soils and accumulate a significant amount of biomass, which is an important argument in favour of the development of green energy. The purpose of this study is to determine the specifics of planning work on the phytoremediation of degraded lands when using energy plants and the subsequent production of fuel pellets and briquettes. The focus is on measures to comply with the requirements for the content of pollutants in solid biofuels, which will be made from energetic plants used in the process of phytoremediation of degraded soils. The ratio of pollutant concentrations in soil and plants to their maximum permissible concentration in biofuel is proposed to be used at phytoremediation planning. This study substantiates recommendations for planning the phytoremediation of soils impacted by military activities using energy plants. These recommendations, in particular, concern: the choice of plant species; estimates of the duration of the phytoremediation process; application of precision farming methods in phytoremediation of lands; use of stochastic models of the phytoremediation process.

The purpose of the article is to present a combined approach that connects several methods and algorithms to increase the effectiveness of the geodetic network measurement structure for determining horizontal and vertical displacements of engineering objects. Determining the deformation of commercial objects and objects of practical value allows to assess their technical condition. In case of critical changes at such objects, appropriate planning of protection, reconstruction and modernization works is also provided and the negative impact of the environment and weather conditions is indicated. Regardless of the methods used, the measurement of movements and deformations of structures is always preceded by an analysis of the prevailing conditions, as well as a network of geodetic measurement determination and control. These analyses are carried out taking into account manufacturability, economy, and safe use of objects, human safety and environmental protection. The target function was defined, which in this case was chosen as the entropy of the geodesic observation network through the measurement of the parameters vector with true values. Analysing the structure of the control and measurement network and improving its efficiency by the number of necessary observations becomes important for determining reliable changes occurring at the object and the ability to conduct the necessary measurements in the shortest possible time. At the same time, the improved network structure should ensure the redundancy of observations made to match the geodetic network with the modified methods. The optimal number of observations in the geodetic network depended on the observation structure informativeness. During the research, it was noticed that the use of a combined approach will allow selecting only those observations that are the most informative. This will reduce the measurement time without reducing the accuracy of the received movements. The obtained results of the numerical analysis showed the performance of the offered solution for increasing the efficiency of the geodetic network structure formation. It also allows faster and more economical performance of engineering structures geodetic measurements.

The purpose of the article is to consider the institutional foundations of the rational use of agricultural land in a multicultural economy. The formation of land use is faced with the acute problem of organizing a sustainable competitive land use, ensuring a high level of marketability of production and a sufficient level of profitability in conditions of the developing land market. This article discusses the rational use of agricultural land in a multicultural economy, taking into account structural and resource indicators. The efficiency of land use in farms with different land ownership depends on increasing labour productivity, strengthening the economic regime, increasing the intensification of production, using internal reserves and agricultural production opportunities, and, especially, rational use of land. The greatest efficiency of production and use of land has been achieved in large agricultural formations, where high-performance equipment is used, crop rotations are observed, and there is greater availability of credit resources, subsidies, and leasing. The monitoring data of the Committee of the Republic of Kazakhstan on Statistics for 1.01.2020 indicate that 93.7% of peasant farms have a land area of up to 500 hectares. To the greatest extent, small-earth peasant farms have become widespread in the southern region, where the share in the total number of up to 50 hectares is 90.1%, while in the northern region only 8.1%, central — 3.9%, and western — 11.3%. In this regard, the tasks of preserving productive agricultural lands, and optimizing arable land and acreage in terms of quantitative and qualitative characteristics of land become a priority. The solution to these tasks is connected with the improvement of technologies for maintaining and increasing the bio-productivity of agricultural lands, the development of technologies for rational land management, land use, and land protection, the creation of effective organizational and legal mechanisms for managing agricultural lands, as well as the development of state monitoring of agricultural lands. Optimization of land use in farms and agricultural enterprises of based on the proposed methodology, taking into account state support measures, will create a basis for a new stage in the development of land reform and will create incentives for the effective use of agricultural land.

Taking into consideration all the data of collectibility of land payments (land tax and rent), the dependence of collectibility of land payments on economic and geographical factors is analysed in municipalities of the Samara region. The factors are defined with the help of mathematical methods, which are closely associated with payments growth from the land area of a municipality and the number of residents. The dependence simulation of the level of land payments on geographical and demographic characteristics has been implemented in a municipality. This model allowed allocating ”normative level” for each municipal district which corresponds to the result of the ”average area” with given objective characteristics. This assessment allowed the authors to identify the areas with high and low levels of land payments collectibility. The efficiency assessment of municipality local governments in the Samara region on land management is made taking into consideration objective factors that limit their opportunities.

Land as a production factor occupies a special position in the economic activities of the urban population. Land resources in big cities are not only territorial basis for placing industrial and production structures, but also a space for urban life in general. However, to assess the effectiveness of urban land use, primarily the ecological and economic potential of the use of the urban land resources should be determined aimed at sustainable development of urban agglomerations (Volodchenkov, 2010). The rapid pace of development of large cities in the world and an increase of their impact on the environment and society is accompanied by the set of economic, ecological and social problems which significantly influence the development of settlements in general (Stolʹberh, 2000; Onyshchuk, 2001). However, the process of urbanization as a result of rapid scientific and technological revolution requires large areas for deployment of large scale production facilities and urban settlements in the conditions of natural resource management (Kontorovich, Rivkin, 1986).

Agricultural land is one of the most valuable natural resources which can be found in Latvia, since agricultural land has long time served as an important resource of economic activity and food production. Efficient use of this valuable resource depends not only on technologies and knowledge at disposal of farmers but also on regulations concerning the real estate market and taxation of the real estate. Recent changes of the real estate market regulation as concerns agricultural land are analysed in this paper to identify a possible influence on the use of agricultural land.

One of the main groups in agriculture is plant cultivation. The crop production combines growing of grain, cotton, vegetable, viticulture, tobacco cultivation, etc. One of the main factors in the activities of plant-growing as well as in grain-growing is the efficient using of land. Agriculture is characterized by number of specific socio-economic, natural and technological characteristics. Unlike other sectors of the economy, the main means of production is land. Land differs from other agricultural production facilities. Land is not a product of human activity, it is the product of nature. The land area cannot be increased nor decreased as other means of production, its natural fertility and productivity can be increased. Land area has been divided into zones according to its location, quality and rating. Agricultural farming on unfavourable land areas requires more funds than on favourable land plots. In the article, using grain crops efficiency data, increase of soil fertility and issues in the direction of increasing productivity facing entrepreneurial farms were studied.

The solution of preserving and restoring the soil fertility problem of agricultural lands in the process of economic activity is one of the main tasks in achieving global food security. Implementation of a complex of soil protection measures, as a rule, ensures the preservation and even growth of soil fertility. Therefore, the purpose of the article is to determine the economic efficiency of introducing soil protection measures in the use of agricultural land. For this purpose, the following tasks were set and solved: the analysis of the current state and trends of the land resources use in agriculture; to investigate the tendencies of carrying out measures on preservation of soil fertility and prevention of its degradation; to substantiate scientific and methodical estimation principles of economic efficiency of introduction of soil protection measures in the conditions of Ukraine. The following basic methods were used to solve the research objectives: monographic analysis – when developing scientific publications on environmentally friendly use of agricultural land; comparative and statistical analysis – in studying the dynamics of the structure of the land fund of Ukraine by main types of land and economic activity; system-structural analysis and grouping – in the study of the nature and content of ecological and economic consequences of soil degradation, as well as approaches to assessing the economic effectiveness of soil protection measures; economic analysis and calculation of relative indicators – to evaluate the economic efficiency of soil protection measures in the process of agricultural land use; abstract-logical method − for theoretical generalizations and conclusions formation, etc. Established that soil degradation is now one of the most important industrial and environmental issues, which is the main reason for the inability to achieve high rates of environmental and economic efficiency of land use in the future. It was also substantiated scientific and methodical approach to determining the economic efficiency of soil conservation measures in the current market conditions, which is based on the additional income that is received as a result of increase crop yields on protected lands. It is established that effective protection of soils from degradation is possible with the systematic implementation of soil protection measures complex, developed taking into account the specific natural and economic conditions of each region or agricultural enterprise. The priority directions of realization measures on land protection are given.

Renovation is seen in the context of an urbanist as a form of large-scale dispersed urban space reorganization. To date, in countries with developed economies, the share of renovation works has increased in the structure of construction from 35% to 60%. In this article, the content of the main stages of renovation is detailed: the definition of the scope, planning, financing and implementation. The article reflects the experience and tasks of the Moscow Government on the renovation of the quarters of the existing buildings. Since the city renovation projects are aimed at achieving the optimal combination of social, residential and commercial functions, the complex reconstruction of the city has noneconomic and economic effects. Varying the key parameters influences the calculation of the project economy. The most economical indicators of the project depend on the coefficients of renovation and relocation, the cost of construction and the price of sales. To increase the additions in Moscow budget and other economic effects from the project implementation, it is necessary to increase the renovation ratio and the selling price and/or reduce the construction cost and resettlement ratio.
