The article raises the issue of changes in the value of land plots depending on their quality characteristics. This study investigated the change in indicators of the monetary assessment of individual agricultural districts (NAD) in connection with the indicators of agricultural production groups of soil quality valuation score. Using the normative indicators of the monetary valuation of land plots, the normative monetary valuation was calculated for 10 natural and agricultural districts of the Kyiv region of Ukraine. Thus, in the Skvyrskyi NAD, the normative monetary value is UAH 37,950.08 per 1 hectare, and the average soil quality valuation score in this area was 55 points by level, which is the highest value of this indicator in the Kyiv region. The lowest credit rating score (15) was recorded in the Chornobyl-Borodyansky NAD, where the norm of capitalized rental income was UAH 10,347.52 per 1 hectare. From 42 to 110 agro-production groups of soils are counted in each of the NADs. Based on the Kyiv region, the average indicators of humus content range from 1.91 to 2.47 %. We established a directly proportional relationship between the soil quality valuation score and humus content, in particular, the correlation coefficient between these indicators ranges from 0.8743 to 0.9376. The research results can be used to carry out land evaluation works on agricultural land. [ABSTRACT FROM AUTHOR]

This article analyses land accounting as part of the State Land Cadastre of Ukraine. It has been proven that, under modern conditions, cadastral accounting can become a reliable basis for soil monitoring in Ukraine. The indicators of land quality accounting and regulations in the field of land protection and reproduction of soil fertility are analysed. The article proposes criteria for land cadastral accounting based on a study of the qualitative state of agricultural lands in a separate region. Factors for ensuring sustainable land use are singled out, taking into account the needs of agricultural production. It has been proven that regular monitoring of land use helps identify problems in time for effective management and optimal use of land. The purpose of the study was to create a system of land cadastral accounting indicators based on best practices and available indicators. The main purpose of this mechanism is to compare and evaluate the land accounting criteria of Ukraine. The materials of the research are land cadastral data built on methodical methods of synthesis and analysis of individual elements. The research methodology consisted of three stages: 1) identification of a number of factors characterizing land quality accounting as a basis for effective monitoring of land; 2) analysis of the methodical basis of land accounting, determination of cadastral accounting indicators; 3) identification of the most optimal land accounting criteria for rational use and land protection using correlation-regression analysis. As a result of the conducted research, it was established that there are a significant number of approaches to accounting for the quality of land in Ukraine, but there is still no unified system of them. The proposed model of accounting for the quality of land in Ukraine will provide a solution to problems of the components of land cadastral accounting as a basis for effective land use.

- Abstract
A system optimization method was used, which consists in the consistent justification of optimal technological and constructive solutions and parameters of drainage polder systems during the development of their projects. This is done in compliance with modern economic and environmental requirements according to criteria and models for di erent levels of management decision-making over time (project, planned operation). Based on the performed relevant predictive and optimization calculations for the conditions of the real object, the following three tasks have been accomplished. (1) The optimal pump module at the stage of operation for the existing polder drainage system has been substantiated. (2) The design of the pumping unit and the parameters of its components during the reconstruction of the polder drainage system have been improved. This made it possible to reduce the load on the pumping equipment, the duration of its operation, and the cost of electricity by 20–40%, depending on the water level of the year. The improvement was carried out by the diversion of the corresponding part of the surface runo with additionally introduced gravity elements in the form of a puncture in the body of the protective dam and a siphon intake. (3) We have substantiated the optimal water regulation technology for the existing polder drainage system in modern and forecast weather and climate conditions, which will ensure the maintenance of the necessary water-air regime of the drained soils in di erent phases of the growing season of agricultural crops. This will make it possible, on demand, to increase the energy and general environmental and economic e ciency during their creation and functioning of the polder drainage system in accordance with modern changing conditions.

The article is devoted to a topical scientific problem in modern conditions – valuation of land in Ukraine. The imperfection of the existing approaches requires further research on the changing conditions of land use and their impact on land pricing. A methodology for determining the market value of reclaimed land based on a differentiated assessment of its productivity through crop yields is proposed, taking into account natural and climatic zones and other conditions of a particular region. The basis of the methodology is the application of long-term forecast and a set of forecast and simulation models, in particular the model of area climatic conditions and the model of water regime and water regulation technologies on reclaimed land. At that the crop yield model as a complex multiplicative type model takes into account all main factors influencing crop yield formation: weather, climatic and soil conditions, cultivation techniques, water regime of reclaimed land, etc. The proposed approaches were tested by the method of large – scale machine experiment using a land plot in the zone of Western Polissya of Ukraine as the example. The obtained results indicate that there is a differentiation in land value, which is a proportional derivative of the yield of cultivated crops depending on the conditions of their cultivation. The variation range of the studied indicators in relative form by the ratio of maximum and minimum values to the weighted average value is for cultivated crops – 393%, and for the above soils – 44.6%. Thus, within one object, the estimated value of land in view of available soils and cultivated crops varies from USD2456∙ha
–1 to USD4005 ∙ ha–1 , averaging USD3522 ∙ ha–1 . [ABSTRACT FROM AUTHOR]- Published

The study delves into a pivotal realm of rural infrastructure management by scrutinizing the efficacy of diverse building survey methodologies. The assessment encompassed laser scanning, total station surveying, and smartphone-enabled LiDAR, encompassing a meticulous evaluation across key dimensions: accuracy, economic cost, and time efficiency. The overarching objective was to pinpoint the most optimal surveying approach tailored for rural landscapes, considering the delicate equilibrium between cost-effectiveness and precision. The study findings illuminate a multifaceted landscape of trade-offs inherent in these methodologies. The findings revealed that the Total Station method, utilizing the GEOMAX ZOOM 10 (2”), emerged as the most expensive among the building measurement techniques, with a cost of 185.04 euros. However, it demonstrated the highest accuracy with an RMS (Root Mean Square) value of 0.0135 m. In contrast, Laser scanning employing the Leica ScanStation C10 had a cost of 149.85 euros, with an RMS value of 0.0205 m. The Lidar method using the iPhone 13 Pro, while being the third most expensive at 128.48 euros, exhibited a comparatively lower accuracy with an RMS value of 0.1694 m. By navigating the intricate interplay between economic considerations and the imperative for precise infrastructure management, this study endeavours to foster sustainable, efficient, and economically viable approaches in rural infrastructure development. The insights garnered herein endeavour to bridge the gap between precision and financial prudence, fostering a pragmatic balance in survey method selection for rural infrastructure initiatives.
