Agrivoltaic systems towards the European green deal and agricultural policies: a review

Excessive exploitation of natural resources has an environmental impact on ecosystems due to demographic and economic growth, and energy demand. For this reason, world economies have been implementing policy tools to achieve eco-friendly energy growth, minimizing environmental impact. It is necessary to increase Renewable Energies (RE) fraction in terms of electricity supply, improve energy efficiency and reduce energy consumption in greenhouses as well as in the agricultural sector. Thus, the European Green Deal (EGD) is a sustainable package of measures which, due to the ecological use of natural resources, strengthens the resilience of European food systems. The EGD’s objectives include: ensuring food security, reducing environmental impact, and supporting the farm to fork strategy and energy communities. The aim of this review is to present innovative energy technologies integrated with agrivoltaic systems to produce and utilize energy with eco-friendly methods. In this review, agrivoltaic systems were presented in the EGD perspective, since, as shown by several studies, they increase simultaneously clean energy production and crop yield, avoiding limitations in land use. As agrivoltaic systems produce energy by the installation of PV panels, an overview of PV technology was provided. PV panels can feed electricity to the power grid. Nowadays, since there are many impoverished rural areas which do not have access to electricity, a lot of projects have been developed that utilize power generation from microgrids combined with hybrid systems (e.g., wind and solar energy) to feed agricultural facilities or community buildings.

The measurement of agricultural disaster vulnerability in China and implications for land-supported agricultural resilience building

Climate change has recently induced an increase in natural disasters worldwide, which has affected agriculture, a sector highly sensitive to climatic alterations. The paper measures agricultural disaster vulnerability of China in the period 2000–2020 by establishing vulnerability assessment system, and examines how agricultural infrastructure correlates with agricultural disaster vulnerability by constructing grey relational analysis model. Research results indicate that China's agricultural disaster vulnerability presents an overall decreasing trend during the research period. This is mainly attributed to the decreased disaster exposure and increased adaptability to disaster. Spatially, the agricultural disaster vulnerability in the northeastern, central and southwestern regions of China is higher than other regions. Agricultural transportation and communication infrastructure are found to be more influential to agricultural disaster vulnerability followed by irrigation and power facilities. Implications are proposed to enhance agricultural resilience to climate disasters in China.

Recent Progress of Phase Change Materials and Their Applications in Facility Agriculture and Related-Buildings—A Review

Facility agriculture, which involves agricultural production in controlled environments such as greenhouses, indoor farms, and vertical farms, aims to maximize efficiency, yield, and quality while minimizing resource consumption and environmental impact. Energy-saving technologies are essential to the green and low-carbon development of facility agriculture. Recently, phase change heat storage (PCHS) systems using phase change materials (PCMs) have gained significant attention due to their high thermal storage density and excellent thermal regulation performance. These systems are particularly promising for applications in facility agriculture and related buildings, such as solar thermal utilization, greenhouse walls, and soil insulation. However, the low thermal conductivity of PCMs presents a challenge for applications requiring rapid heat transfer. This study aims to provide a comprehensive review of the types, thermophysical properties, and various forms of PCMs, including macro-encapsulated PCMs, shape-stabilized PCMs, and phase change capsules (PCCs), as well as their preparation methods. The research methodology involves an in-depth analysis of these PCMs and their applications in active and passive PCHS systems within facility agriculture and related buildings. The major conclusion of this study highlights the critical role of PCMs in advancing energy-saving technologies in facility agriculture. By enhancing PCM performance, optimizing latent heat storage systems, and integrating intelligent environmental control, this work provides essential guidelines for designing more efficient and sustainable agricultural structures. The article will serve as the fundamental guideline to design more robust structures for facility agriculture and related buildings.

Grid-Connected Photovoltaic System for Generating Energy to Dairy Farm Activities

Minas Gerais is the leading milk-producing state in Brazil, and many dairy activities are supplied with electricity by the cable aerial network of the electrical energy state company. Given that the Brazilian energy matrix relies primarily on hydroelectric power, studies on the potential of other renewable energy sources in the context of dairy farms are innovative. Additionally, frequent disturbances and interruptions have motivated the installation of solar energy systems on dairy farms. However, the scarcity of technical and scientific studies demonstrating the benefits of electricity generated from photovoltaic panels in Minas Gerais has caused dairy farmers to fear potential financial losses. In this study, grid-connected photovoltaic systems in dairy farms were evaluated, considering three fixed tilt angles for the panels (latitude - 10°, latitude, and latitude + 10°) and electrical energy demands of dairy activities associated with two herd sizes (100 and 150 cows). Meteorological databases and mathematical models were used to predict daily global radiation on tilted panels in dairy farms of two Brazilian municipalities of Minas Gerais State (Lavras and Paracatu). Energy consumption related to dairy activities was monitored for 12 months. For both municipalities, the best results were verified with the tilt angle of panels equal to the local latitude - 10°. The municipality with the lowest latitude (Paracatu) showed higher electricity generation potential. In all simulated scenarios, a greater energy surplus was found from late spring to early autumn (Southern Hemisphere), when the higher electricity generation by the photovoltaic panels met the elevated electrical energy demand of the dairy farms. A high energy surplus was also verified during midwinter, where lower energy consumption by the dairy farms compensated for the reduced availability of solar radiation. The proposed methodology can be adapted to other dairy farms, agricultural and urban buildings.

Former Oesing Kitchen Colonial Building in Banyuwangi as Urban Heritage

Banyuwangi Regency is rich in pen-colonial legacy. Colonial remains can still be found in several parts of the city, but quite a few have changed form, even looking different from their original state. One of the buildings is the former Oesing kitchen. The research aims to explore the facade-forming and space-forming elements in the former Oesing Kitchen, Banyuwangi, and the condition of the former Oesing building after restoration. The research method used is qualitative, with data collection techniques through observation, interviews, and documentation. The colonial buildings selected as study cases were carried out using purposive sampling techniques using several criteria. Data analysis was carried out inductively with greater emphasis on historical meaning and value. The results of the observations are a way to explain and conclude the two elements that form the architectural character of these colonial buildings. The research results show that the former Oesing kitchen building has an architectural character that can be determined from the windows, entrance, roof, and walls. Meanwhile, other characters can be determined from the basic plan and shape of the building. Apart from that, there are historical supporting objects such as chimneys, old tombs, nagabulan, and agricultural buildings.

A globalized methodology of energy-saving solar greenhouse design in high latitudes

The energy-saving solar greenhouse (ESSG) represents a Chinese-type agricultural building of facilitating low-energy and zero-carbon vegetable overwintering production in high latitudes and cold regions. However, its application benefit outside of China has been limited. To establish an operational ESSG design scheme applicable worldwide, this study developed a comprehensive methodology and specific parameters for different latitudinal regions. The ESSG design was determined based on considerations of daylighting, thermal insulation, heat storage-release capacity, and structural safety. Through validation in six representative regions, the reliability of the ESSG design methodology was confirmed. The optimal design values for front roof angle, ridge height, and back wall height were identified across different latitudes. ESSG in various latitudinal regions from 32°N to 48°N exhibited annual cumulative temperatures could reach 8 × 103∼1.3 × 104°C and accumulated light interception could reach 2 × 1012∼4 × 1012J. Even in the 48°N region, the average internal temperature of the greenhouse exceeded 8 °C, with a nighttime cooling rate lower than 0.75 °C/h and a maximum temperature difference between internal and external environments exceeding 40 °C. This suggests the ESSG fully meets the non-heated overwintering production requirements for common vegetables. The research findings provide crucial theoretical foundations for the global promotion of ESSG, contributing to the reduction of energy consumption and carbon emissions in the sustainable agriculture.

Tenacity of Animal Disease Viruses on Wood Surfaces Relevant to Animal Husbandry

The aim of this study was to analyse the hygienic suitability of wood often used in animal husbandry. To this end, the inactivation of viruses (Enterovirus E as a surrogate for non-enveloped viruses and Newcastle disease virus as a surrogate for enveloped viruses) on germ carriers consisting of various types of wood was studied over an extended period to assess the biosafety of wood as an agricultural building material. The study was designed to assess the intrinsic biocidal activity of the wood itself, without the use of a disinfectant. The laboratory tests were based on German test guidelines and current European standards. Five different types of wood germ carriers, i.e., spruce (Picea abies), pine (Pinus sylvestris), poplar (Populus sp.), beech (Fagus sylvatica) and Douglas fir (Pseudotsuga menziesii), as well as stainless-steel carriers, were inoculated with enveloped and non-enveloped viruses and stored for up to four months, and the remaining infectivity of the viruses was continuously assessed. The results showed that intact, finely sawn timber with a low depth of roughness had an inactivating effect on the viruses up to 7.5 decadal logarithmic levels. For the non-enveloped virus, inactivation was fastest on Douglas fir wood, with the target reduction for effective inactivation (reduction by factor 4.0 log10) being achieved after two weeks, and for the enveloped virus on pine wood, it was already achieved from the day of drying. The hygienic effects of the wood carriers may be due to their hygroscopic properties and wood constituents. These effects offer potential for further investigation, including tests with other wood species rich in extractives.

Local social-ecological context explains seasonal rural-rural migration of the poorest in south-west Bangladesh

Bangladesh is one of the countries most affected by climate change. Internal migration is often presented as a response to environmental degradation. Here, using a people-centred perspective, we explore the complexity of the links between climate-induced change, environmental degradation caused by waterlogging and seasonal rural migration. We used an inductive qualitative approach in social sciences, conducting fourteen semi-directed interviews and six focus group discussions in March-April 2022. We related those results to a rainfall analysis on CHIRPS data for 1981-2021and we represented interactions and feedback between changes and livelihoods in a model. A complex picture of the situation is emerging, showing the interweaving effects of non-climatic and climatic changes, their interplay at different scales, their cumulative effects, the interactions between livelihood types and feedback between social and natural systems. Most of the climate-induced changes gradually become noticeable over the past 25 years. Climate data confirm these changes in recent decades, with July being wetter and January being dryer. Villagers reported waterlogging as the most significant change in their community, pointing to its multiple causes, originating in non-local and local, non-climatic anthropic changes, exacerbated by shrimp farm enclosures and worsened by climate-induced changes such as heavier rains, wetter monsoons and cyclones. Tiger prawn farms, reported as a lucrative and local adaptation to waterlogging and salinisation for the ones who can afford it, worsen the situation for the less wealthy, causing waterlogging and salinisation of the adjacent agricultural lands and buildings, the disappearance of traditional fishing and a reduction of the local job market. In addition, erratic rain patterns, droughts and cyclones affect local production and labour markets. COVID-19 lockdowns, by impacting markets and mobilities, further aggravated the situation. Inequality has increased as the range of adaptations of the less wealthy appears limited in this context of multiple crises.

Fotovoltaické elektrárny ve víru veřejných zájmů

Europe is undergoing a massive transition to electricity generation from renewable energy sources. Photovoltaic power plants, representing one of the main renewable energy sources, require a lot of space, which is why agricultural land and building roofs are considered to be most suitable for such projects. However, performed analysis in the field of agricultural land, landscape or cultural heritage protection has shown that other public interests often constitute an important obstacle to the development of photovoltaic power plants, especially when the values represented by these interests are significantly affected by the project. The aim of this paper is to identify such cases, in addition to situations where the installation of photovoltaic power plants would be compatible with these public interests.

Laser Rangefinder Methods: Autonomous-Vehicle Trajectory Control in Horticultural Plantings

This article presents a developed motion control system for a robotic platform based on laser-ranging methods, a graph traversal algorithm and the search for the optimal path. The algorithm was implemented in an agricultural building and in the field. As a result, the most efficient algorithm for finding the optimal path (A*) for the robotic platform was chosen when performing various technological operations. In the Rviz visualization environment, a program code was developed for planning the movement path and setting the points of the movement trajectory in real time. To find the optimal navigation graph in an artificial garden, an application was developed using the C# programming language and Visual Studio 2019. The results of the experiments showed that field conditions can differ significantly from laboratory conditions, while the positioning accuracy is significantly lower. The statistical processing of the experimental data showed that, for the movement of a robotic platform along a given trajectory in the field, the most effective conditions are as follows: speed: 2.5 km/h; illumination: 109,600 lux; distance to the tree: 0.5 m. An analysis of the operating parameters of the LiDAR sensor showed that it provides a high degree of positioning accuracy under various lighting conditions at various speeds in the aisles of a garden 3 m wide with an inter-stem distance of 1.5 m and a tree crown width of 0.5 m. The use of sensors—rangefinders of the optical range—allows for the performance of positional movements of the robotic platform and ensures the autonomous performance of the basic technological operations of the units in intensive gardens with a deviation from the specified trajectory of no more than 8.4 cm, which meets the agrotechnical requirements.

Carbonated balsa-based shape-stable phase change materials with photothermal conversion and application in greenhouse

Greenhouse enables to promote plant yield through creating optimal environment. Efficient solar energy conversion and storage is a promising strategy to address energy shortage issue of greenhouse in winter. This paper prepares form-stable composite phase change materials (PCMs) to store solar energy efficiently. Lightweight and porous balsa wood subjected to high-temperature carbonization is designed to simultaneously solve the liquid leakage, enhance the thermal conductivity, and improve the photothermal conversion and thermal energy storage of PCM. OP44E and SEBS are utilized as PCM and thickener, followed by vacuum impregnation into the carbonized balsa wood (CW). Results indicate that carbon content of CW increases with the augment of carbonization temperature. Shaping effects of CW and SEBS endow composite PCMs to have highest adsorption rate of 92.7 wt% with enthalpy over 190 J/g. Composite PCMs reveal reliable thermal properties and thermal stability below 100 °C. Composite PCMs have photothermal conversion larger than 88 % under a xenon lamp radiation. Temperature of PCMs on the shallow layer is higher owing to its photothermal conversion capacity. Greenhouse test indicates that CW/OP44E/SEBS greenhouse gains higher PCM temperature of 71.5 °C at 70 min, compared to 40.3 °C in empty and OP44E/SEBS cases. CW/OP44E/SEBS greenhouse maintaining indoor temperature over 20 °C lasts 15.3 min longer than empty and OP44E/SEBS greenhouses. In addition, form-stable composite PCMs featured with excellent thermal stability and photothermal conversion are capable of maintaining stable indoor temperature of greenhouse, indicating potential in the field of agricultural building temperature regulation.

Analysis of wind pressure characteristics of typical agricultural greenhouse buildings on tropical islands

Existing studies about wind pressure on agricultural greenhouse buildings concentrate on the mean wind pressure while ignoring the systematic research on fluctuating wind pressure characteristics and the influence of roof shape on the wind pressure characteristics, which are closely associated with the wind-induced damage mechanism. In this study, two typical agricultural greenhouse buildings on tropical islands are selected as prototypes to conduct pressure measurement experiments in the wind tunnel. Based on the wind pressure time series for the two greenhouses, the mean and fluctuating wind pressure distribution pattern and the localized high-pressure generation mechanism are analyzed. Then, the shape coefficient of the two greenhouses is compared in depth to the standards from four countries. Besides, wind pressure non-Gaussian determination criteria for agricultural greenhouse buildings considering the roof shape and wind directions are proposed. Lastly, the differences in wind pressure spectra on the roofs and walls of the two greenhouses are summarized. The results indicate the roof shape has a significant influence on the wind pressure characteristics. Compared with the pitched roof, the vaulted roof will increase the suction effect on the windward front zone and the middle area, mitigate the suction impact on the leeward roof, and weaken the wind pressure non-Gaussian characteristics. The experimental shape coefficient of the pitched-roof greenhouse is basically consistent with the standard from the U.S., while that of the vaulted-roof greenhouse has some deviation from the existing standards. The results provide a theoretical basis for the wind-resistant design of agricultural greenhouse buildings on tropical islands.

Skreen, County Meath—from ancient burial ground to medieval manorial village

Abstract: This paper presents the results of the first detailed archaeological survey of the Hill of Skreen, an important multiperiod site that is closely linked—topographically, historically, and symbolically—with the Hill of Tara, 3km to its west. Skreen's early ancestry as a burial ground laid a foundation for the establishment, in or before 976, of a church dedicated to Colum Cille ( Scrín Columb Chille ) and, some two hundred years later, an Anglo-Norman manor. Few extant remains of pre-Anglo-Norman date survive and, beyond the Columban church and motte marking the caput of the manor granted to Adam de Feypo, an array of low-relief earthworks provides the only visible trace of an associated settlement. High-resolution aerial and geophysical surveys conducted as part of the Discovery Programme's Tara Research Project, combined with documentary and cartographic evidence, reveal the wider imprint of past occupation at Skreen in remarkable detail. There is now evidence to suggest that the church is circumscribed by a large, subrectangular enclosure and that this putative ecclesiastical boundary may be an original feature of the Columban foundation. The Anglo-Norman manorial settlement that developed around the church and castle, moreover, is shown to be far more extensive, and indeed significant, than previously recognised. The core area of the medieval village of Skreen, extending to more than 30ha, was demarcated by an earthwork boundary, of hexagonal plan, and encompassed a complex network of roads, property divisions, domestic and agricultural buildings, enclosures and fields. These bear witness to the vibrant and dynamic 'market settlement' of which we catch such intriguing glimpses in contemporary historical records. Skreen thus presents a case study of particular relevance to the field of medieval settlement studies, with significant potential for further research.

INFLUENCE OF VOCATIONAL EDUCATION PROGRAMMES ON SUSTAINABLE COMMUNITY DEVELOPMENT IN OGBA/EGBEMA/NDONI LOCAL GOVERNMENT AREA OF RIVERS STATE

The study assessed the influence of Vocational Education Programs on Sustainable Community Development in Ogba/Egbema/Ndoni Local Government Area of Rivers State. The study adopted the descriptive survey design. The population of the study is 625 which comprised 445 Community Development Committee (CDC) members and 180 beneficiaries of vocational education programs in Ogba/Egbema/Ndoni Local Government Area of Rivers State. The entire 180 beneficiaries were sampled; while the proportionate sampling technique was adopted in selecting 25% of the population of CDC members to arrive at the size of 89 CDC members, making a total of 269. Three research questions were posed. A questionnaire titled “Influence of Vocational Education Programs on Sustainable Community Development Assessment Questionnaire” (IVESCDAQ) was used for data collection. Data was analyzed using frequencies, means and standard deviation. The findings revealed that agricultural education, craft education and building technology programs influenced sustainable development in the area of study. Based on these findings, the researcher recommended, amongst others, that Local Government Authorities should establish craft training centers in each local government to empower beneficiaries with skills that will enable them to be self-employed. The acquired skills will increase individual’s economic well-being and enhance sustainable community development.

Stress relaxation of concrete beams caused by creep and shrinkage effects

Shrinkage and creep are two important physical properties of concrete material which cause increase of the deformation of the constantly loaded structure over long period of time, the feature known as rheology. Additional deformation of concrete structures at the end of the design working period (most commonly 50 years) caused by these phenomena is circa three times larger than the value of the immediate elastic deformation (or even larger in some cases). Hence, in accordance with the corresponding European standard, these effects should be taken in account while evaluating the serviceability limit state of concrete structures, and if significant, consideration of these phenomena is also needed for the verification of the ultimate limit state. In concrete material, creep occurs at all stress levels, and is dependent on many parameters, as cement class, concrete grade, relative humidity of the environment, surface of the structure in contact with the ambient air (drying surface), and the age of concrete (after casting) at the loading moment. Shrinkage of the concrete is independent on loading. It is caused by decrease of the pore water content in the hardened concrete, and is predominantly dependent on the ambient relative humidity. Relaxation describes stress reduction at a constant material strain, usually in prestressing steel tendons. In this study, the physical experiments of multiple concrete beams over time with respect to rheological processes are described. Each experimental system consists of two C35/45 beams horizontally bounded by a prestressed steel cylinder. Decrease of these pretension forces in cylinders over time have been monitored (stress relaxation). All together time histories of two forces are documented, based on measurements conducted in interior environment of an agricultural building. The experimental time histories of the pretension forces are then compared with the results of the finite element numerical analyses conducted in ANSYS software. Creep and shrinkage effects of the concrete material have been considered based on the corresponding European standard for design of the concrete structures. The time-histories of the forces in prestressed cylinders obtained from the numerical simulations are then compared with the experimental data, and discussed. It is concluded, that the estimation of the force decrease over analysed time with the creep and shrinkage effects considered according to the corresponding European standard appears to be slightly larger than the experimentally measured decrease of the force value, hence the assumption is more conservative.

Электрический озонатор-излучатель воздуха для сельскохозяйственных помещений:результаты исследований автономного модуля

The air environment of livestock buildings requires disinfection and improvement of the gas composition. The most effective method is ozonation. In order to improve the air inside livestock buildings, the authors have developed an electric ozonizer-emitter. Its emitter module consists of two ceramic bases with different-potential tungsten electrodes, one base having an electrode in the form of a honeycomb cell, and the other - in the form of a rod. The ozone productivity is regulated by changing the discharge gap between the emitter electrodes and the conducting plane. It has been theoretically established that ozone formation in a corona discharge depends on the electric field strength between the different-potential electrodes and their heating temperature. In this case, the maximum strength is achieved with a discharge gap from 25 to 35 mm and electrodes with a radius of no more than 2 mm. The effect of electrode heating temperature on ozone formation was studied on the developed design of the ozonizer-emitter in a laboratory of 180 m3 at an air temperature of 25°C above zero. The air gap between the electrodes was 30 mm, the voltage on the emitter varied from 10 to 30 kV, the duration of the ozonizer-emitter operation ranged between 0 and 80 min, the airflow rate induced by the electric fan was 0.3 m/s. It was experimentally established that stable operation of the ozonizer-emitter is observed when the electrode temperature does not exceed 30°C. In the future, the authors plan to introduce the ozonizer-air emitter into the ventilation and air conditioning system of agricultural buildings.

Organized natural air exchange in the room for the maintenance of animals

The organization of effective ventilation is a key task in the construction and reconstruction of animal housing. Insufficient air exchange in the room leads to the accumulation of harmful gases released by cows: water vapor, methane, nitrogen compounds and carbon dioxide, which causes not only deterioration of animal health, but also increases the heat hazard of premises. The article aims to substantiate the use of natural air exchange in the warm season in agricultural buildings for milk production. The required opening angle of the swing-out flaps of the window openings was determined to achieve a normalized air flow in the animal housing. The option of organizing an additional air flow through the opening of the entrance gate and its effect during the summer period of the year is considered. Studies have shown that the inflow of air through the external gate significantly increases the overall air exchange in the premises for cattle. As a result of the study of the issue, the article presents a method for determining the necessary air exchange for the assimilation of excess heat, moisture and carbon dioxide emissions by animals.

不同保温覆盖措施对日光温室温度环境的影响

Chinese solar greenhouses (CSGs) are the important agricultural building facility with highly efficient and sustainable utilization of solar energy. In order to improve the thermal insulation performance and reduce the heat loss, different insulation cover measures were applied to Chinese solar greenhouses. In this study, a solar greenhouse with an internal insulation blanket (SG1), a greenhouse with an internal blanket and an internal plastic film (SG2) and a greenhouse with an external blanket, an internal blanket and an internal plastic film (SG3) were chosen as experimental objects to analyze their indoor temperature environment. The results indicated that the differences of solar radiation interior among three greenhouses were similar, which was not the main reason that caused the differences of the temperature environment in the three greenhouses. During the tests, the nighttime average temperature was increased by 2.1-3°C by adding the cover materials, and the duration of nighttime temperature greater than 8°C was increased by 33.5%-38.2%. In addition, the cost is increased by adding the insulation cover materials, but it will be beneficial for greenhouse production to reduce additional energy consumption

The Role of Financial Services in the Transition to a Sustainable Economy

The financial services industry plays a critical role in the transition to a sustainable economy. Financial institutions can allocate resources to more environmentally friendly endeavors, manage long-term sustainability risks, and provide financing for sustainable projects.
 One way that financial institutions can support the transition to a sustainable economy is by allocating capital to more environmentally friendly investments. This could include investing in renewable energy, sustainable agriculture, and green buildings. Financial institutions can also help to manage long-term sustainability risks by developing and implementing climate risk management frameworks. This will help to protect investors and financial markets from the potential financial impacts of climate change.
 Finally, financial institutions can provide financing for sustainable projects through a variety of mechanisms, such as green bonds and sustainable loans. This financing can help to accelerate the deployment of clean technologies and other sustainable solutions.

Agro-ecological state of land resources of Kamianets-Podilskyi distrist of Khmelnytskyi region

The peculiarities of the agro ecological state of land resources of Kamianets Podilskyi district have been analyzed in the article. The structure of the agricultural lands of the district, the ecological condition and ecological sustainability of land resources has been studied. The territorial differences in the land use structure in Kamiantes-Podilskyi TC have been defined. Based on the conducted research we have found out the main type the land use within all the TC of the district is the agricultural, which is evidenced by the high level of agricultural development (76,3 %). The highest rate of agricultural development is in Chemerivtsi TC (84 %). In the structure of agricultural lands the largest part in all TCs is taken up by arable land. The agricultural lands dominate in the structure of the land fund and take up 358,20 thousand ha. Arable land takes up 223,4 thousand ha, perennial plantations – 19,5 thousand ha, pastures and hayfields – 89,9 thousands ha, fallow lands – 0,37 thousand ha, agricultural buildings – 7,59 thousand ha. Based on such indicators as the structure of agricultural land, the area of arable land, and the area of agricultural land we have analyzed the intensity and the level of agricultural development and plowed territory of the district. A significant area within the district is occupied by agricultural land – 333,2 thousand ha. The largest share in the structure of agricultural land is occupied by arable land – 67,2 %. The share of hayfields and pastures is 26,8 %, and perennial plantations – 5,8 %. The high share of arable land (67,2 %) in the structure of agricultural land and the agricultural development (76,3 %) of the territory of the district affects the structure of the land fund of both the individual TCs and the district overall and determines the efficiency of the use of land resources. In the structure of agricultural land, hayfields and pastures occupy smaller areas than arable land (34.402,8 ha and 55.576,5 ha, respectively). The share of these lands in the structure of agricultural lands is 26,8 %. Within the district, there is a certain territorial differentiation in terms of indicators of the ecological state, ecological sustainability and anthropogenic transformation. The average index of ecological sustainability of land resources for the Kamianets-Podilskyi district is 0,81. Thus, the land resources of the district can be attributed to the group of conditionally sustainable. Anthropogenic transformation within Kamianets-Podilsky district varies from the maximum of 7,5 in Kamianets-Podilskyi TC to the minimum in Orynyn TC – 5,9. When analyzing the territorial features of the location of the TC according to this indicator, it has been found out that the southern and eastern parts of the district have an average level of anthropogenic transformation. The average indicator of anthropogenic transformation within the district is 6,27. The following pattern is observed between the indicators of ecological sustainability and anthropogenic transformation: in TCs where anthropogenic transformation is very strong, the ecological sustainability of land is low (non-sustainable land). Conservation and reproduction of land resources is especially relevant for the Podilia region, including the Kamianets-Podilskyi district, as land resources are the main type of resources here. The basis of the balanced use of land resources is the combination of their functions: ecological, economic and social. Keywords: land resources, structure of agricultural lands, ecological sustainability, anthropogenic impact, ecological state.
