The study analyzes the possibilities of using cost estimates of ecosystem services to assess the effects of transformations in land use. The consequences of transformations were assessed by comparing the value of basic ecosystem services for different patterns of the land use structure, taking into account the fact that the volume of ecosystem services provided is limited by the ecosystem sustainability limits. To estimate ecosystem services, the methodology developed by the author was used. It is based on the indicators of agricultural land productivity and their value terms. The assessment was carried out for the Zarinsky district of Altai Krai, located at the junction of the West Siberian and Altai-Sayan physicogeographical countries. The study has revealed that the greatest value of basic ecosystem services in the region with agricultural specialization can be achieved by optimizing the agricultural load – reducing the share of arable land and increasing the share of forage land in the total area. It is proposed to implement this by involving plots of fallow lands in circulation: some of the plots are proposed to be used for reforestation, while others – for haying and grazing. This will balance the need to maximize agricultural production, while not reducing the sustainability of the ecosystems.

The subject of the study presented in this article is the economic relations arising due to the progress of the urbanization that leads to changes in agricultural production. For a long time in Russia a reduction of agricultural land, arable land and crops takes place. One reason for this is the global progress of urbanization. Changes in agricultural land use occur across the country however this process is uneven in different regions. Among all regions Moscow and Moscow region significantly stand out. The study showed that in the more urbanized regions of the country reduction of the agricultural land and changes in agricultural land use are greater than in less urbanized ones.

The paper studies the issue of the use of disposed agricultural land through the example of LLC “Alliance-agro in Sengileevsky district of the Ulyanovsk region. The authors consider the grounds for cultural and technical work and provide the results of a survey of unused arable land on the farm. A technology for the development of disposed agricultural land is proposed. Everyone knows that agricultural land is of particular importance as a means of agricultural production and is the second largest category of land in the unified land fund of the Russian Federation in terms of area, which includes the best and fertile lands making up the heritage of the country. Despite the fact that the schemes for the use of agricultural land are developed, many questions of a theoretical, methodological and applied nature need to be improved, since this is associated with incessant changes in the legal and organizational systems of land use. As a result of irrational use of land, degradation, littering, overgrowing with trees and shrubs of agricultural areas occurs. These processes lead to the fact that fertile lands are withdrawn from circulation. Our research is aimed to solve the problems in the field of the improvement of the cadastral registration of lands, the process of the organization of rational land use, as well as the most effective use of unused lands overgrown with trees and shrubs. The solution to this problem will help the rational transformation of the agricultural land use system and increase in their efficiency. Moreover it will help to solve the problem of the involvement of unused land in agricultural production and increase the efficiency of cadastral registration of agricultural land. As a result of the land clearing proposed by the authors, the sites of this object will be put into agricultural circulation, where any zoned agricultural crop can be grown from the first year of development in case of a favorable water-air regime in the root layer and complex agrochemical cultivation.

Agricultural land use systems have been optimized for producing provisioning ecosystem services (ES) in the past few decades, often at the expense of regulating and cultural services. Research has focused mainly on the supply side of ES and related trade-offs, but the demand side for regulatory services remains largely neglected. The objective of this paper is to evaluate the usefulness of participatory geographic information system (PGIS) methods for demand assessment in larger rural and agrarian contexts by identifying spatially explicit demand patterns for ES, thereby enlarging the body of participatory approaches to ES-based land use management. Accordingly, we map, assess, and statistically and spatially analyze different demands for five ES by different stakeholder groups in agricultural landscapes in three case studies. The results are presented in a stakeholder workshop and prerequisites for collaborative ES management are discussed. Our results show that poor correlation exists between stakeholder groups and demands for ES; however, arable land constitutes the highest share of the mapped area of demands for the five ES. These results have been validated by both the survey and the stakeholder workshop. Our study concludes that PGIS represents a useful tool to link demand assessments and landscape management systematically, especially for decision support systems.

Agricultural land is an important natural resource and forms the basis for food production. Global and local socio-economic and environmental changes are often the driving forces of changes in land cover and land use. Land abandonment in rural areas is one of the processes observed in Europe today and usually leads to increased afforestation. The intensity of this process in Central Europe is linked to the political and economic changes that took place at the end of the 20th century. The study objective was to identify the natural and socio-economic factors of this process in Lublin Province—a major region of agricultural production in Poland. From 1990 to 2018, over 130,000 ha were excluded from agricultural use, which represents 7% of the arable land in 1990. Land abandonment showed considerable spatial differences when comparing different counties: its magnitude ranged from 4% to 13% of the county area. At the same time, due to the specific type of land use in the province (small farm holdings divided into several fields), the intensity of land abandonment was underestimated when based on overview data (CORINE). It was observed that the intensity of this process was correlated with the natural conditions (topography, soils) for agricultural production and the socio-economic characteristics (area of arable land, forest cover changes, farm size) of the counties as well as the absorption of Common Agricultural Policy funds.

<p>According to the latest IPCC report, 70 to 85% of electricity generation worldwide will need to come from renewable sources of energy by 2050 if countries are to meet internationally agreed greenhouse gas emissions targets. In the rush to decarbonise energy supplies to meet such targets, solar parks (SPs) have proliferated around the world, with uncertain implications for the biodiversity and ecosystem service (ES) provision of hosting ecosystems. SPs necessitate significant land-use change that could disproportionately affect the local environment compared to other low-carbon sources.</p><p>In Britain, SPs are commonly built on intensive arable land and managed as grasslands. This offers both risks and opportunities for ecosystem health, yet evidence for assessing ecosystem consequences is scarce. Therefore, there is an urgent need to understand how net environmental gains can be integrated into land-use change for solar energy development to address the current biodiversity and climate crises.</p><p>We used vegetation data from over 70 SPs and 50 countryside survey plots (1 km<sup>2</sup>) in England and Wales to assess the effects of land-use change for SPs on plant diversity and ES provision. We assessed ten habitat indicator variables (e.g., species richness, larval food plants, forage grasses, bird food plants) associated to functionally important plant species that have the potential to enhance ecosystem service delivery.</p><p>SPs showed higher diversity of habitat indicator species than arable land and improved grasslands, with vegetation between solar arrays showing higher numbers of species important for ES provision (e.g., N-fixing species important for nutrient cycling) than vegetation under solar panels. Overall, the diversity of habitat indicator species seemed highly dependent on former land-use, showing SPs have the potential to enhance ecosystem services provision if built on degraded agricultural land.</p><p>Developing this understanding will enable optimisation of SP design and management to ensure delivery of ecosystem co-benefits from this growing land-use.</p>

The article analyzes the state of land reproduction as a factor of production. The author describes the lands of agriculture in terms of the main means of production. Considerable attention is paid to the analysis of fertility, which in the article is divided into natural, artificial, potential, efficient and economic. The author notes that nature itself forms the primary fertility of the land, which in the process of agricultural land use is reduced. The natural fertility of the land with its effective use makes it possible to organize the production of various products necessary for human life. Therefore, the expansion of agricultural land and a qualitative increase in their fertility are becoming an extremely important area of increasing the production of various types of agricultural products. It is also noted that along with soil fertility, it is necessary to assess the possibility of different land use. It is noted that in the last ten years there has been a steady trend of reduction of fallow lands with a slight decrease in agricultural land and almost unchanged area of arable land, we can say about the intensive use of land as a factor of production. One of the effective ways to increase fertility and as a consequence of improving the land as a factor of production is the introduction of mineral and organic fertilizers. Analysis of the dynamics of fertilizer application by agricultural enterprises over the past two decades shows a tendency to increase their volume as a whole and per 1 hectare. In general, the process of land reclamation as a factor of production is to develop measures to reduce soil acidity and salinity, land reclamation, application of organic and mineral fertilizers. The need for constant care to increase land fertility and its rational use is caused by the limited cultivated area of agricultural land used for agricultural production and to meet the growing needs of the population in food. As a result of the article, the author noted that the output per unit of arable land and agricultural land in recent years is growing. At the same time, land potential is declining. To this end, measures are needed to preserve land resources in agricultural production, prevent the redevelopment of agricultural land, increase the efficiency of their use, taking into account the prospect of their demand in the short and medium term.

Smallholder agriculture is a major source of income and food for developing nations. With more frequent drought and increasing scarcity of arable land, more accurate land-use planning tools are needed to allocate land resources to support regional agricultural activity. To address this need, we created Land Capability Classification (LCC) system maps using data from two digital soil maps, which were compared with measurements from 1305 field sites in the Dosso region of Niger. Based on these, we developed 250 m gridded maps of LCC values across the region. Across the region, land is severely limited for agricultural use because of low available water-holding capacity (AWC) that limits dry season agricultural potential, especially without irrigation, and requires more frequent irrigation where supplemental water is available. If the AWC limitation is removed in the LCC algorithm (i.e., simulating the use of sufficient irrigation or a much higher and more evenly distributed rainfall), the dominant limitations become less severe and more spatially varied. Finally, we used additional soil fertility data from the field samples to illustrate the value of collecting contemporary data for dynamic soil properties that are critical for crop production, including soil organic carbon, phosphorus and nitrogen.

The main trends in changing the land use structure in the territory of the Klyazma River basin were de-scribed in the article. Using GIS technologies and remote sensing data the areas of land with different land use regimes in the studied territory were determined in the period from 2001 to 2019. The indices of LAI and FPAR phytoproductivity for the territory of the Klyazma basin as a whole, and for each basin included in it were determined. The analysis of the dynamics of changes occurring in the structure of land use is carried out. For the territory of Vladimir region, which is a part of the Klyazma River basin, an assessment of soil types distribution over occupied area was carried out. An integral indicator of soil fertility was calcu-lated on the basis of statistical data of agrochemical indicators. The fraction of fallow lands decreased by 2019 and it amounts 33.76% of the total area of the studied territory. The fraction of mixed forests increased from 38.48% in 2001 to 44.50% in 2019 due to the formation of fast-growing tree species shoots on fallow lands. The area of meadow vegetation for the period from 2015 to 2019 decreased by 3.5%, from 4 276 to 3 121 km2, due to agriculture degradation and a significant decrease in livestock grazing. The indicator of soil fertility for the Klyazma basin was 0.74, which is a high indicator. It is established that the most active decrease in the agricultural land area occurs in the central, north-western and western parts of the river basin.

The land use has undergone some changes in the last 30 years, by reducing the areas with arable land, converting multi-annual plantations into other categories of land, etc. According to the current mode of land use, the Northern Development Region has a pronounced agricultural profile - 80.3% of the total area represents agricultural land. The spatial differentiations regarding the morphological and agro-climatic conditions allowed the identification within the region of areas with agro-forestry and agro-pastoral specializations.
