Methodological basis of the development of the institutional environment of the land management system
2024
Tretiak, Anton | Hunko, Liudmyla | Hetmanchyk, Ivanna | Zamlynskyi, Serhii
It is substantiated that the institutional concepts of the latest institutional and behavioural economic theory should be placed in the methodological basis of the development of the institutional environment of the land management system. Institutions and institutes are the key to understanding the relationships between all subjects of the economic system of land management, and institutional changes determine the direction of its development and are a defining trend today. The institutional system in the field of land relations, land use and land management is a set of organically interconnected institutions and institutes that are a certain logically complete, integral unity, capable of self-development and self-reproduction, as well as organizations and individuals that act within given institutional restrictions regarding land relations and organization of land use. Firstly, the methodology of institutionalization of land management considers socio-economic systems through holistic development. The principle of the integrity of the socio-economic system research includes an interdisciplinary approach. Secondly, individuals receive characteristics through the prism of the existence of institutions and institutes that condition their behaviour and interaction. Thirdly, institutional changes require not only quantitative, but also qualitative methods of observation, which analyse not the results of changes (for example, indicators of efficiency and growth), but the direction, strategy and the very process of evolution with the clarification of the causes, all stages and forms of transformations.

Matviienko, Oleksii | Kurach, Tamara
In the era of the high level of technological achievements of remote sensing of the Earth and the high level of development of web cartography, interactive web applications for the analysis of data of remote sensing of the Earth are gaining more and more popularity. Considering the large amount of space image data, and the complexity and heterogeneity of the analysis tools that need to be developed, the question arises of quickly and efficiently creating an interactive web application for the analysis of space images that will help scientists monitor and study changes in the Earth's surface and predict optimal ways of territory development with minimal expenditure of time and resources. In solving such a question, the specialized web platform Google Earth Engine (GEE) can help. The purpose of the article is to highlight the characteristics and advantages of the GEE platform by creating an interactive web application using the example of analysing changes in the NDVI index. Analysing GEE allows us to conclude that this web-platform provides a comprehensive solution for creating interactive cartographic web applications for the analysis of space images with a built-in IDE. It will help to significantly reduce development time and costs, allowing for quick and efficient analysis of Earth remote sensing data.

2023
Raspopina, Svitlana | Suska, Anastasiia | Nazarenko, Vitalii | Opashniuk, Anna
The indirect approach is mainly used to assess the forest-growing potential of lands in the forestry of Ukraine. For these purposes, a comparative ecological (forest typological) method is used to assess soil conditions according to their forest growth effect. The species composition of the forest stand and its productivity are the main indicators of the forest growth effect. The undoubted advantages of this method are high forestry value, low labour intensity and cost, and the main disadvantages are the subjectivity of determining the types of forest conditions (especially derivatives and artificial plantations), its insufficient environmental sensitivity, and the difficulty of applying to places where there is no forest vegetation. The aim of the study was to quantify the quality of forest land and develop markers of the forest-growing potential of soils. The studies were carried out by synthesizing two methodological approaches – forest typological as the leading method for assessing the potential of habitats and direct study of soils (field and analytical). The package of markers was developed to assess forest potential of soils based on the establishment of a correlation between the productivity of forest stands (height, quality class) and soil indicators (thickness of the humus part of the profile, pH, content of clay particles, humus, total and exchange forms of N, P, K, Ca, Mg). The package of markers depends on the soil type and consists of the following soil indicators: the content of particles of physical clay (d<0.01 mm), the thickness of the humus part, as well as the content of humus, N, Ca, K, and Mg. A gradual increase in their quantitative values leads to increase in the forest productivity of the soil and, as a result, the productivity of the forest stand.

2024
Ivavičiūtė, Giedrė
Greenspaces are an important component of the complex ecosystem. Trees and green spaces are also very important to human well-being as well. It is widely known that trees and green spaces give environmental, social, economic and psychological benefits. For example they affect microclimates to reduce the heat effect, improve air quality. Understanding the relationship between population size and the quality and quantity of green spaces is vital for the sustainability, health and resilience of areas. Analysis of the current situation of the trees and shrubs greenery area in Klaipeda County was accomplished. The study also provides the trees and shrubs greenery area changes analysis in Klaipeda County and in the municipalities of the county. In Klaipeda County the area under trees and shrubs in 2002 was 4,758.14 ha. In 2022 the plantation area amounted to 10,793.50 hectares. From 2002 to 2022 the area of tree and shrub plantations in Klaipeda County increased by 6,035.36 ha or 127 percent. The development of plantation areas has been positively influenced by the creation of an appropriate legislative framework and the implementation of plantation programmes in municipalities.

2024
Bavrovska, Nataliia
The pre-war state of land resources in most of Ukraine was characterized as strained, and sometimes critical, with a tendency to deteriorate, which significantly complicated the socio-economic development of Ukraine and its regions and negatively affected the landscape and biological diversity, health and living conditions of the population. The article examines topical issues of problems and prospects for the use of land resources of Ukraine in the conditions of martial law and post-war reconstruction. As a result of Russia’s military aggression, Ukraine faced mass shelling, missile strikes, radiation contamination, air pollution, littering of territories, unburied or chaotically buried bodies of the dead, mining and other challenges. This has led to aggravation of economic, environmental and social challenges of food supply both in Ukraine and in the world. In connection with military actions, the land resources of Ukraine are subjected to large-scale destruction, deterioration of the soil quality, degradation processes are intensified, land resources are damaged, owners and land users suffer material losses. Agricultural lands suffered two significant types of damage – mine contamination, both on the frontline and in occupied (or formerly occupied) territories, and direct physical damage, from contamination by mines and unexploded ordnance. As of March 20, 2022, the area of damaged soil cover was 6,582.0 hectares, out of 1,655,845.3 hectares of surveyed arable land. For rational use and protection of land, restoration of soils and improvement of their fertility, preservation of productive, ecological and social functions of soil cover, the following important measures should be implemented: actualization of scientific research on the restoration of degraded soils, in particular in the direction of studying the impact of armed aggression of the Russian Federation on the soil cover of Ukraine; determination of the current state of soil health; improvement of the methodology for determining the amount of damage and losses to land and soil resources caused by armed aggression; development and pilot implementation of rehabilitation technologies for war-damaged soils.

Zhildikbaeva, Aizhan | Gurskiene, Virginija | Yelemessov, Serik | Ablaikhan, Baukhan
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.

Krasinskaite, Karina | Valciukiene, Jolanta | Jukneliene, Daiva
The article presents an analysis of changes in the agrarian landscape and the subdivision of its plots, using three Lithuanian municipalities as examples (Kaunas, Trakai and Šilutė). Statistical, comparative and multicriteria analysis methods were applied in the study. It was found that in all the studied municipalities, the area of the agrarian landscape was decreasing during the study period. The largest decreasing trends were in the municipality of Šilutė district, where the area covered by agrarian landscape decreased by more than 3%. At the same time, in the municipalities of Kaunas and Trakai districts, the area of agrarian landscape decreased quite evenly and did not reach 3%. It was also found that the number of agricultural holdings also decreased: by 27% in Kaunas district municipality and by over 33% in Trakai district municipality, but the area of agricultural holdings increased in all of the studied municipalities: in Kaunas district by over 5%, in Trakai district by over 37% and in Šilutė district by over 8%. The average size of a farm in Kaunas district remained rather stable, increasing by only 1%, in Šilutė district municipality the average farm size increased by more than 71% and in Trakai district municipality the tendency was the opposite, i.e. the average farm size decreased by more than 36%. The multicriteria analysis shows that the most common factors influencing changes in the agrarian landscape and its subdivision of plots vary between municipalities, but in general the following factors influence the changes in the agrarian landscape and its subdivision of plots: the land productivity score, the number of inhabitants, the distance to the centre of the city, the average size of the farms, the number of holdings, and the amount of land area occupied by bodies of water. The information collected and the results obtained show that in the municipalities analysed, the causes of change in the agrarian landscape and its subdivision of plots have a positive impact on the sustainable development of agriculture and rural areas.

2023
Koshkalda, Iryna | Sadovyy, Ivan | Dombrovska, Olena | Gurskiene, Virginija | Maliene, Vida
Aspects and factors of agricultural land transformation are analysed in the work. Taking into account the world experience of land transformation, directions for improving the development and control system of land management projects implementation in Ukraine are offered. The compliance issue by land users with established types of agricultural land according to the data of state registers is highlighted. Nowadays, land management projects that provide ecological and economic substantiation of crop rotation and land management make it possible to develop environmentally safe and economically feasible land use projects. In production, the above-mentioned projects are sometimes used to transfer ecologically stabilizing lands (pastures and hayfields) to arable land. This is controversial to all recommendations, conventions and programs that emphasize the need for reduced ploughing of the territory. It is necessary to improve the control mechanisms of crop rotation and agrotechnical environmental protection measures. The introduction of land plots agricultural passports is an important but insufficient measure. The remote sensing data of the earth and the use of modern geoinformation technologies should become part of the state control over compliance with land management projects. There is already experience of using various indices at the state level to decipher agricultural crops. As a result of the research, we came to the conclusion that the use of land remote sensing data and modern geoinformation technologies in land management will make it possible to bring the indicators of ploughed areas to a rational level, while not creating artificial restrictions on economic activity. The methodical and regulatory acts for the development of land management projects, which regulate the size of the ecologically safe land area need improvement. agricultural lands transformation, land management project,

2023
Suska, Anastasiia | Shevchenko, Serhii | Valčiukiene, Jolanta | Jukneliene, Daiva | Opashniuk, Anna
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.

2023
Aleknavičius, Audrius
The paper’s main objective is to analyse the distribution of large farm plots and opportunities for their optimization. In the context of intensive changes in the management and use of agricultural land, it is particularly important to optimise the land holdings of large farms. Most large farms are characterised by a fragmented, uncompacted spatial distribution. 15 large farms were selected for analysis in Jonava municipality. There are 22 separate fields on average per holding, 2/3 of the farm centres (farmsteads) are located in large settlements, and 1/3 of the farm centres are located in one-farm settlements and in small villages. It was found that the average area of individually cultivated fields is 14.9 ha, and the average distance from the farmstead to the fields is 4.35 km. Land holdings are very fragmented – fragmentation coefficient K2 value range from 2.64 to 8.81 (average 3.62) for selected farms. It is proposed to draw up municipality land use planning schemes, which would project the prospective boundaries of land holdings, and to legalize by law the right of pre-emption for the farm owner to acquire the ownership of the plots of land to be sold within these boundaries in order to increase the compactness of farm land holdings. A state can facilitate sporadic land consolidation by farmers through the preparation of the proposed municipality land use planning schemes.
