Spatial–temporal evolution analysis of multi-scenario land use and carbon storage based on PLUS-InVEST model: A case study in Dalian, China

Carbon storage in terrestrial ecosystems varies with land use changes, and exploring the impact of land use changes on carbon storage in regional terrestrial ecosystems is important for maintaining regional carbon balance. Data on Dalian City’s land use types from 2000 to 2020 are used in this research, to evaluate the spatio-temporal evolution of carbon storage in Dalian. Furthermore, with the scenarios of urban development, natural development, cultivated land protection, and ecological protection in 2030, this study combines the PLUS and InVEST models to emulate the dynamic adjustment at land-use types and the spatio-temporal evolution regarding carbon storage in Dalian City. The investigation shows that: 1) The carbon storage of terrestrial ecosystem in Dalian has been altered as a consequence of changes in land use, and now it shows a general decline during 2000–2020, with reductions amounting to 5.39 × 106 t. 2) From 2000 through 2020, Dalian’s land resources that are utilized for farming, forestry, and grassland decreased to different degrees. The total construction land area increased by 796.47 km2, or 6.38 %, whereas there has been no substantial improvement in water or unused land. 3) The carbon storage reduction in 2030 in comparison to 2020 for the natural development, cultivated land protection, and urban development scenarios, among which the urban development scenario was the largest, was 1.36 × 106t.It suggests that the rapid rate of urbanization and expansion of constructionlandis an important cause of the decline in carbon storage. 4) The cultivated land protection scenario (CPS) yields the smallest reduction of 6.50 × 105t. The structure of Dalian’s land use type is optimum under the ecological protection scenario (EPS), as seen by the 3.90 × 105t increase in carbon storage under this scenario. It speeds up the rate of recovery of carbon storage and improves the function of carbon sinks in urban terrestrial ecosystems. Hoping to provide the reference to decision makers for ecosystem carbon storage optimization from the view of land use, which is vital for making future land use policies and realizing the “dual carbon” strategic goal.

Research on policy and regulations on changing of forest land to other land uses in Vietnam

The Land Law of 2013 and the legal regulatory framework have established provisions for repurposing forest land for other uses. However, due to the widespread conversion of forest land to non-agricultural purposes and a lack of effective control, existing policies and laws exhibit certain shortcomings. Specifically, legal challenges arise from contradictions among related laws (such as the Land Law, Planning Law, Forestry Law) regarding the authority to approve the repurposing of protective and special-use forest land for alternative purposes. Additionally, the process for such repurposing is complex and lacks sufficient rigor. The main objective of this article is to propose refinements to the land policy and legal framework concerning the repurposing of protective and special-use forest land. A study collected input from 50 managers in two provinces (Quang Ninh and Lao Cai) to assess the appropriateness and direction of amendments to the land policy and laws on this matter. An evaluation of the current state of land repurposing in 12 provinces, representing six economic and social regions of the country from 2014÷2020, showed that 276.662 ha of protective forest land and 55.057 ha of special-use forest land were repurposed. The research results have proposed amendments to several articles of the 2013 Land Law and highlighted some key discussion points.

Strategi Pengendalian Alih Fungsi Lahan Pertanian Pangan di Kawasan Mamminasata Provinsi Sulawesi Selatan

The conversion of food land functions in the Mamminasata Region of South Sulawesi Province, is always increasing due to urban growth, population development, emigration and the economy. This study aims to determine the strategy for controlling the conversion of agricultural land functions in order to implement Law No.41/2009 and Regional Regulation No. 4 tahun 2014 concerning the protection of sustainable agricultural land in the Mamminasata area of ​​South Sulawesi province. The type of research used is a combination of qualitative and quantitative methods. This research was conducted in the Mamminasata Region, South Sulawesi Province from October to December 2016. Primary data collection was obtained using landsat 7 ETM maps and Spot 4 imagery and interpretation. Secondary data was obtained from government stakeholder interviews, surveys and direct interviews with local communities systematically and based on research objectives, causal factors based on survey results, interviews from informants and the public are external factors, internal and policy factors, then thus to overcome these problems a sustainable food land control strategy must be carried out including: Strengthening farmer institutions and related agencies, Protection and empowerment of land-owning farmers, Utilizing and protecting sustainable food agricultural land, providing incentives and disincentives to land owners, sharecroppers , and farmer groups, optimizing sustainable food agriculture land: by means of intensification, extensification and diversification of agricultural land, imposing sanctions and penalties on those who violate regional regulations and RTRW, and following up RI Law No. 4 tahun 2014 and South Sulawesi provincial regional regulations no. 4 of 2014 to determine the zoning of sustainable food agricultural land in the Mamminasata area as one of the food storages in South Sulawesi.

The Spatiotemporal Correlation between Human Activity Intensity and the Evolution of Ecosystem Service Value in the Songnen Plain, China

For the main grain-producing areas worldwide that balance multi-tasks of grain production, ecological protection, and economic development, quantitatively revealing the correlation between human activity intensity (HAI) and ecosystem service value (ESV) is conducive to formulating adapted ecological protection policies and promoting the coordinated development of the regional economy, society, and ecosystem. In this paper, we took the Songnen Plain of China as an example, employed a modified Equivalent Factor Method (integrating socio-economic data, the normalized difference vegetation index (NDVI), and land use data), and the HAI Assessment Model (based on the data of land use, night-time light, and population spatial distribution) to measure the ESV and HAI in the Songnen Plain of China for the years 1990, 1995, 2000, 2005, 2010, 2015, and 2020. We further applied the standard deviational ellipse method, the coupled coordination degree model, and the bivariate spatial autocorrelation models to reveal the spatiotemporal dynamics and correlation characteristics of ESV and HAI. The results showed the following: (1) Temporally, the ESV declined from 950.96 billion yuan in 1990 to 836.31 billion yuan in 2015, and then increased to 864.60 billion yuan in 2020, with the total loss attributed to the significant decline in the ESV of the natural ecosystem. Spatially, the ESV in the western and northeastern regions was relatively high, with a significant increase in the northeast. (2) HAI showed an upward trend from 1990 to 2020, while the high HAI levels gradually shrank after reaching the peak in 2000. Low HAI levels were mainly distributed in the northeast and southwest, aligning with the ecological space, while high HAI levels were distributed in the middle and southeast. (3) The interaction between ESV and HAI was marked by a negative correlation, transitioning from conflict to coordination. The spatial pattern of HAI and ESV showed H (HAI)-L (ESV) and L-H clustering, with H-H and L-L scattered distributions. This study contributes to providing a framework, methods, and suggestions for the sustainable planning and utilization of land and ecological protection in order to offer scientific references for the Songnen Plain, other major grain-producing areas, and related studies.

Stations of the Ottoman Period in Iraqi Kurdistan: Preliminary Results from the Bazhera Archaeological Project

In 2023, an archaeological research project was initiated by the University of Udine, in cooperation with the Dohuk Directorate of Antiquities and Heritage of the Kurdistan Region of Iraq, on the site of Bazhera, on the eastern bank of the Nahr al-Khazir, in the Akre district. The site consists of a partially standing building, which would have played a role in the communication system of the region during the late Islamic period, as one of the stations in support of travellers. The main objective of the project is to reconstruct the functioning of this structure, its material culture and its relationship with other archaeological remains identified on the settlement and with the surrounding landscape, in order to provide new data regarding land management and protection of a frontier region of the Ottoman empire which has been neglected by archaeological research.

GCAM–GLORY v1.0: representing global reservoir water storage in a multi-sector human–Earth system model

Abstract. Reservoirs play a significant role in modifying the spatiotemporal availability of surface water to meet multi-sector human demands, despite representing a relatively small fraction of the global water budget. Yet the integrated modeling frameworks that explore the interactions among climate, land, energy, water, and socioeconomic systems at a global scale often contain limited representations of water storage dynamics that incorporate feedbacks from other systems. In this study, we implement a representation of water storage in the Global Change Analysis Model (GCAM) to enable the exploration of the future role (e.g., expansion) of reservoir water storage globally in meeting demands for, and evolving in response to interactions with, the climate, land, and energy systems. GCAM represents 235 global water basins, operates at 5-year time steps, and uses supply curves to capture economic competition among renewable water (now including reservoirs), non-renewable groundwater, and desalination. Our approach consists of developing the GLObal Reservoir Yield (GLORY) model, which uses a linear programming (LP)-based optimization algorithm and dynamically linking GLORY with GCAM. The new coupled GCAM–GLORY approach improves the representation of reservoir water storage in GCAM in several ways. First, the GLORY model identifies the cost of supplying increasing levels of water supply from reservoir storage by considering regional physical and economic factors, such as evolving monthly reservoir inflows and demands, and the leveled cost of constructing additional reservoir storage capacity. Second, by passing those costs to GCAM, GLORY enables the exploration of future regional reservoir expansion pathways and their response to climate and socioeconomic drivers. To guide the model toward reasonable reservoir expansion pathways, GLORY applies a diverse array of feasibility constraints related to protected land, population, water sources, and cropland. Finally, the GLORY–GCAM feedback loop allows evolving water demands from GCAM to inform GLORY, resulting in an updated supply curve at each time step, thus enabling GCAM to establish a more meaningful economic value of water. This study improves our understanding of the sensitivity of reservoir water supply to multiple physical and economic dimensions, such as sub-annual variations in climate conditions and human water demands, especially for basins experiencing socioeconomic droughts.

Projecting the long‐term effects of large‐scale human influence on the spatial and functional persistence of extant longleaf pine ecosystems in the Florida Flatwoods Pyrome

AbstractDecades of human activities and fire suppression have adversely affected longleaf pine (Pinus palustris) ecosystems, which are home to high levels of diversity and endemism. These iconic ecosystems also now face challenges from urbanization and climate change, which will alter conservation outcomes over the remainder of the 21st century. To explore how long‐term, large‐scale human influences could affect the spatial and functional persistence of extant longleaf pine ecosystems in the Florida Flatwoods Pyrome, we extracted a set of 2400 longleaf pine patches ≥40 ha in size from the Florida Longleaf Pine Ecosystem Geodatabase. Projections from the FUTURES urban growth model and the Florida 2070 project indicate that development will lead to losses of existing longleaf pine habitat, reductions in longleaf pine patch size, and patches that are predominantly located in close proximity to developed areas. Finer‐scale patterns of longleaf pine loss in three focal landscapes highlighted differences in land protection, ecological setting, and development pressure and the value of using of multiple urbanization iterations. The occurrence of suitable conditions to conduct prescribed fires, a crucial tool for maintaining, improving, and restoring longleaf pine ecosystems, is projected to decrease seasonally throughout the study area. As a result, the functional persistence of ecosystems is at risk due to climate changes that increase barriers to the safe and reliable application of intentional fire. The long‐term viability of this critical ecosystem will warrant the evaluation of adaptive strategies that explicitly account for the individual and compounding effects of urban development and changing fire management conditions when considering options for ecosystem protection, management, and restoration.

Saline–Alkali Soil Reclamation Contributes to Soil Health Improvement in China

Soil salinization is a significant threat to soil health, especially to the agricultural ecosystem; it reduces vegetation biomass, destroys ecosystem diversity, and limits land use efficiency. This area of investigation has garnered extensive attention in China, especially in the arid and semi-arid areas, totaling 7.66 × 106 ha. A variety of theoretical research and technology developments have contributed to soil water and salt regulation and the screening of salt-tolerant varieties to improve nutrient utilization efficiency and microbial control and reduce ecological problems due to saline-based obstacles. These techniques can be classified into physical treatments, chemical treatments, biological treatments, and combined treatments; these different measures are all aimed at primarily solving saline–alkali stress. In general, the improvement and utilization of saline–alkali soil contribute to soil health improvement, concentrating on high-quality development, food security, ecological security, cultivated land protection, and agricultural upgrading. However, the risks of various technologies in the practical production process should be highlighted; green and healthy measures are still expected to be applied to saline–alkali land.

Strategic land conservation: An applied, multi‐target approach to prioritization of resilient sites for protection

AbstractLand trusts have historically selected many project sites opportunistically, awaiting communication from willing sellers or donors interested in conserving their land. However, in light of the multiple ecological crises faced by land trusts, including climate change, biodiversity loss, and habitat destruction, there is a growing awareness of the need to practice land conservation with an increased pace, scale, and efficacy. In answer to that challenge, we provide one example of how a land trust can adopt methodology for the strategic selection of land protection project sites. Strategic land conservation, as demonstrated in this paper, involves thoughtful prioritization of the attributes of future conservation project sites. Following prioritization, spatial analysis of the region is conducted to identify sites that meet the prioritized attributes, in this case, resilience to climate change. The case study explored in this paper is the 2020 Strategic Land Conservation Plan created by Southwest Michigan Land Conservancy and its partners.

Vulnerability assessment of natural heritage in the North-Eastern Ecuadorian Amazon using land use cover and nature protection status

This study evaluates the vulnerability of natural heritage in the Northeast Ecuadorian Amazon (NEA), from the perspective of intrinsic vulnerability. Therefore, two proxy indicators of vulnerability were established: (i) the ecological integrity vulnerability index (EIVI), indicating the potential loss of ecological integrity, assessed by protection status (2018); (ii) the biological diversity vulnerability index (BVI), deriving the potential loss of biological diversity, using land cover/land use (2014). Biodiversity values were derived with land cover-related biodiversity data, and (iii) and compared with spatial congruence/correlation between (i) and (ii). The EIVI was directly derived using protection status, which defines vulnerability levels by ranking them according to corresponding levels of anthropic development allowance. A robust relationship between land use classes and species richness was found for both endemic vascular plants in neotropical regions and multi-taxa in tropical forests worldwide, validating the BVI. Furthermore, the moderate spatial correlation between protection status and land cover (r = 0.52) may be partially explained by 3,060 km2 of unprotected primary forest. Overall, 42 % of the NEA have a high degree of congruence between potential biodiversity and protection status. In conclusion, this study provides insights into nature conservation efforts in areas with sparse biodiversity data using readily available geographic information.

Evolution Characteristics of Cultivated Land Protection Policy in China Based on Smith Policy Implementation

(1) Background: In the context of the Sustainable Development Goals (SDGs) and based on the historical evolution of cultivated land protection policy, we used the Smith model to address the problem of policy implementation bias and provide recommendations on how to ensure that cultivated land protection policy does not deviate in the implementation process. (2) Methods: The historical evolution process of China’s cultivated land protection policy was elucidated using literature analysis and the inductive deduction method; moreover, the issues regarding local evolution were investigated. In addition, utilizing the Smith model, which has an important role in policy implementation, the restoration direction of cultivated land protection in China was summarized. (3) Project: China’s cultivated land protection policy has demonstrated success in two stages of its historical development—from the basic stage of pursuing equal quantity and quality to the new stage of the trinity of “quantity–quality–ecology” of cultivated land. However, the trend of cultivated land protection policy development based on the regional division of labor in China still has some problems, i.e., the total quantity of cultivated land is insufficient, the quality is low, and the implementation of the trinity is unclear. These regional divisions depend on solving the balance of China’s grain security, and using the Smith model to solve the problem of policy implementation has become an important measure to resolve the issue of grain security and achieve the goal of cultivated land protection. (4) Conclusions: The Smith model is suitable for the implementation of China’s cultivated land protection policy. By utilizing the Smith model, the policy target group was found to be conducive to contributing to the maturity of and improvement in China’s cultivated land protection policy.

Groundwater-dependent ecosystem map exposes global dryland protection needs

Groundwater is the most ubiquitous source of liquid freshwater globally, yet its role in supporting diverse ecosystems is rarely acknowledged1,2. However, the location and extent of groundwater-dependent ecosystems (GDEs) are unknown in many geographies, and protection measures are lacking1,3. Here, we map GDEs at high-resolution (roughly 30 m) and find them present on more than one-third of global drylands analysed, including important global biodiversity hotspots4. GDEs are more extensive and contiguous in landscapes dominated by pastoralism with lower rates of groundwater depletion, suggesting that many GDEs are likely to have already been lost due to water and land use practices. Nevertheless, 53% of GDEs exist within regions showing declining groundwater trends, which highlights the urgent need to protect GDEs from the threat of groundwater depletion. However, we found that only 21% of GDEs exist on protected lands or in jurisdictions with sustainable groundwater management policies, invoking a call to action to protect these vital ecosystems. Furthermore, we examine the linkage of GDEs with cultural and socio-economic factors in the Greater Sahel region, where GDEs play an essential role in supporting biodiversity and rural livelihoods, to explore other means for protection of GDEs in politically unstable regions. Our GDE map provides critical information for prioritizing and developing policies and protection mechanisms across various local, regional or international scales to safeguard these important ecosystems and the societies dependent on them.

Geographic Drivers of Mercury Entry into Aquatic Food Webs Revealed by Mercury Stable Isotopes in Dragonfly Larvae.

Atmospheric mercury (Hg) emissions and subsequent transport and deposition are major concerns within protected lands, including national parks, where Hg can bioaccumulate to levels detrimental to human and wildlife health. Despite this risk to biological resources, there is limited understanding of the relative importance of different Hg sources and delivery pathways within the protected regions. Here, we used Hg stable isotope measurements within a single aquatic bioindicator, dragonfly larvae, to determine if these tracers can resolve spatial patterns in Hg sources, delivery mechanisms, and aquatic cycling at a national scale. Mercury isotope values in dragonfly tissues varied among habitat types (e.g., lentic, lotic, and wetland) and geographic location. Photochemical-derived isotope fractionation was habitat-dependent and influenced by factors that impact light penetration directly or indirectly, including dissolved organic matter, canopy cover, and total phosphorus. Strong patterns for Δ200Hg emerged in the western United States, highlighting the relative importance of wet deposition sources in arid regions in contrast to dry deposition delivery in forested regions. This work demonstrates the efficacy of dragonfly larvae as biosentinels for Hg isotope studies due to their ubiquity across freshwater ecosystems and ability to track variation in Hg sources and processing attributed to small-scale habitat and large-scale regional patterns.

Socio-economic and environmental trade-offs in Amazonian protected areas and Indigenous territories revealed by assessing competing land uses.

Protected area (PA) assessments rarely evaluate socio-economic and environmental impacts relative to competing land uses, limiting understanding of socio-environmental trade-offs from efforts to protect 30% of the globe by 2030. Here we assess deforestation and poverty outcomes (fiscal income, income inequality, sanitation and literacy) between 2000 and 2010 of strict PAs (SPAs), sustainable-use PAs (SUPAs) and Indigenous territories (ITs) compared with different land uses (agriculture and mining concessions) across ~5,500 census tracts in the Brazilian Legal Amazon. ITs reduced deforestation relative to all alternative land uses (48-83%) but had smaller socio-economic benefits compared with other protection types and land uses (18-36% depending on outcome), indicating that Indigenous communities experience socio-economic trade-offs. By contrast, SUPAs, and potentially SPAs, did not reduce deforestation relative to small-scale agriculture (landholdings <10 ha) but did so relative to larger agricultural landholdings (70-82%). Critically, these reductions in deforestation frequently occurred without negative socio-economic outcomes. By contrast, ITs and SUPAs protected against deforestation from mining, but at the cost of smaller improvements in income and inequality. Our results suggest that although PAs in the Brazilian Legal Amazon substantially reduced deforestation without compromising local socio-economic development, efforts to secure Indigenous rights need additional interventions to ensure these communities are not further disadvantaged.

Research on the Implementation of Customary Law in the Protection of Forests and Forest Land by Ethnic Minorities in Đắk Lắk Province (Vietnam) today

Livelihood methods and the transition from subsistence production to commodity production are factors affecting current communities and also influence the changes in nature and the capacity of communities in managing and using natural resources. This article is conducted based on the collection, evaluation, and analysis of current Vietnamese legal documents and policies on Land, Forest Protection and Development, Civil Codes, sub-law resolutions, and other local documents. It also involves analyzing documents on the current state of forests, forest land, ethnic minority groups, and their customary laws. The content of the article provides an overall picture of the current state of using customary law in the management and use of forests and forest land in ethnic minority communities at the study sites.

Wetland Distribution Prediction Based on CA–Markov Model under Current Land Use and Protection Policy in Sanjiang Plain

The conflict between grain production and wetland resource protection in plain wetland is prominent. Understanding the future impacts of current land use policies on wetlands is the key to rationally evaluating and adjusting these policies. Therefore, the objective of the research was to predict the potential distribution of Sanjiang plain wetland under the current land use and protection policy using remote sensing images and CA Markov models. Methodologically, Landsat TM remote sensing images of the Sanjiang Plain (2010–2020) were used to extract wetland distribution based on object-oriented methods, and the characteristics and patterns of wetland change caused by the land use and protection policies during this period were analyzed. A CA–Markov model was used to predict the potential distribution of Sanjiang Plain wetland in 2030, 2040, 2050, and 2060. Then, we summarized the advantages and disadvantages of current land use policies and put forward adjustment measures. The results indicate that during 2010 and 2020, the wetland area of Sanjiang Plain decreased by 22.34%. The conversion ratio of wetland to non-wetland type (mainly farmland) in the first half and the second half of the decade was 46.41% and 15.31%, respectively, and the decrease in wetland showed an obvious slowing trend. The spatial distribution prediction in future showed that the wetland area will continue to decline in 2030, and the decline will basically stop in 2040. Finally, the proportion of wetland area will remain at 8.68% of the total area of Sanjiang Plain, with that of some counties and cities less than 5%. It is concluded that, although the current land use policies in Sanjiang Plain can effectively slow down the wetland area shrinking and stabilize the spatial pattern, a very low proportion of wetland area in some areas will make it difficult for the wetland ecosystem to exert ecological functions and ensure regional ecological security. The wetland conservation managers should adjust the current land use policies according to relevant requirements of farmland protection policies and restore the areal proportion and spatial pattern of wetland in order to help with regional sustainable development.

CURRENT STATUS AND EFFICIENCY OF ABANDONED LANDS RE-DEVELOPMENT IN RIVER BASINS OF SOUTH-WESTERN TRANSBAIKALIA

Complex ecological and economic studies of post-agrarian landscapes in the middle reaches of the Selenga, Chikoy and Temnik rivers were carried out within the boundaries of the Selenga administrative region of the Republic of Buryatia (RB). A map of abandoned agricultural lands has been compiled. A brief description of agroclimatic conditions of the study area is given; the structure of agricultural land, the yield of grain and forage crops, the dynamics of livestock and the load of livestock on pastures and hayfields are analyzed. The reasons for the arable land abandonment are formulated. It was revealed that pastures and hayfields are not excluded from the agricultural use. This is due to an increase in the livestock numbers in households, which are the main agricultural producers in the RB, as well as a shortage of natural forage lands. The species composition and the state of shelterbelt forests are described as an integral part of the ecotopes of post-agrarian landscapes. The main taxonomic indicators of trees are given. The study of shelterbelt forests is topical due to the need for their inventory, lack of maintenance, and the adoption of Federal Laws on protective afforestation and land reclamation. A brief agrochemical description of the state of soils in key areas is given. To assess the effectiveness of arable land reuse, a net operating income (NOI) or rental income was calculated for each grain and grainfodder crop grown in the region under study. It was revealed that oats and spring wheat are the most profitable. Recommendations were formulated for the redevelopment of post-agricultural landscapes, optimization of protective afforestation, and reconstruction of shelterbelt forests

Tree hollow decline in new forest reserves with a long history of logging

AbstractIn many parts of the world, achieving a target of 30% of land managed for conservation under the Kunming‐Montreal Global Biodiversity Framework will require the protection of land with a long history of management for production. In newly protected forests, past logging practices will have impacted key aspects of stand structure, including hollow‐bearing trees that provide critical habitat for vertebrate fauna. The impacts of past silvicultural practices on hollow density, distribution, type and longevity may necessitate targeted ameliorative actions. We investigated tree hollows in the largest river red gum (Eucalyptus camaldulensis Denh.) forest in the world, which had undergone logging‐induced woody thickening prior to being converted to a conservation reserve in 2010. We recorded stem diameters and hollows in living and dead trees in 66 two‐hectare plots. Our sites sampled two productivity states and a wide range of total tree densities. On all sites, we found that hollow‐bearing tree densities were lower than reference values for unlogged stands and average density had halved relative to reference values. We found no relationship between the density of hollow‐bearing trees and total tree density, but we did find a weak positive relationship with site productivity. Larger trees had more hollows, bigger hollows and a greater diversity of hollow sizes. However, of the 1254 hollow‐bearing trees recorded, 43% were dead, 48% of the dead trees had been ringbarked. The proportion of hollow‐bearing trees that were dead was positively correlated with tree size, with 60% of trees in the largest quartile (&gt;105 cm) recorded as dead. The prevalence of dead hollow‐bearing trees suggests that the density and diversity of hollows will continue to decline and ameliorative actions should be considered. These results highlight the need to consider the legacy of past silvicultural practices in the management of newly created conservation reserves.

Ландшафтно-экологическое территориальное зонирование (на материалах Акмолинской области)

Introduction. Modern human activities in nature are subject to increasing regulation and restrictions, which should be reflected in systems for the use of natural resources, primarily in agricultural production. The problem under consideration is of particular relevance for the regions of Northern Kazakhstan, since the natural landscapes of the region have been radically changed and transformed into natural and agricultural complexes with a disturbed landscape-ecological balance.From the point of view of modern natural science, the organization of the rational use of rural areas should be solved by applying a concept based on the landscape-ecological approach. The purpose of the study. Territorial zoning of the agricultural landscape to optimize the use of agricultural land based on the landscape-ecological approach. Research methods. Cartographic materials used as the basis for the creation of diagrams and design developments, obtained on the basis of data from the virtual information system of the land cadastre of the Republic of Kazakhstan and processed using the ArcGIS program. Research results. Based on materials from the steppe zone of the Akmola region of the Republic of Kazakhstan, an analysis of landscape conditions and ecological stability of agricultural landscape systems was carried out. Analysis of territorial landscape zoning allowed us to conclude that the predominant part of the field landscapes of the steppe eons of this region is occupied by natural-territorial complexes of watershed spaces and watershed slopes, and the most common form of relief is slope surfaces. Ecological zoning of agricultural landscapes in the Akmola region revealed that the most common agricultural landscapes are characterized by weak stability and unstable agricultural landscapes. The article proposes a methodology for territorial zoning of agricultural lands on a landscape-ecological basis in the conditions of the Akmola region. It includes the following procedure: drawing up a landscape map. identification of homogeneous ecological zones; agrolandscape microzoning. As a result of research at the research object, a scheme of territorial landscape-ecological zoning for land use of agricultural formations was compiled, which is based on taking into account the paradynamic landscape structure of steppe landscapes and the degree of their anthropogenic transformation. At the same time, relatively homogeneous landscape-ecological microzones were identified, within which the elementary landscapes of the steppe catena were differentiated according to measures that stabilize the stability of the agricultural landscape. Conclusions. 1. On the territory of the Akmola region, natural landscapes have been transformed into agricultural production modifications. with a low degree of sustainability, requiring measures to maintain landscape-ecological balance. 2. The methodology for territorial zoning of steppe agricultural landscapes should be based on taking into account the paradynamic landscape structure of steppe landscapes, i.e. its catenary device. 3. Application of the results of territorial landscape-ecological zoning in design developments for the use and protection of land will allow the selection of optimal directions that ensure the sustainability of agricultural landscapes.

ТЕОРЕТИЧНІ ОСНОВИ УПРАВЛІННЯ ЗЕМЕЛЬНИМ КАПІТАЛОМ ФЕРМЕРСЬКИХ ГОСПОДАРСТВ

The efficiency of farmers' management significantly depends on the effective management of land capital. It has been established that the management of land capital of farms is a system that covers all social relations and generally determines the set of relationships between the elements of the management system aimed at the rational and environmentally responsible land use. The subsystems of land capital management of farms are economic, environmental, regulatory, administrative, innovation and management, and land management and technological. The structural model of the system of land capital management of farms includes the subject, object, subject matter, purpose, goals, principles, functions, methods and mechanisms of management. The subject of this system, i.e., the management subsystem, are farms and government authorities of all levels that implement the state land, agrarian and tax policies and supervise compliance with the norms of rational land use. The object of management is differentiated by the depth of the essential content of the definition of “land”, covering land and its fertility, land resources and their capitalization, land and its investment attractiveness, agricultural land (by type) and the efficiency of its usage. The economic interests of landowners, land users, the state, and society are the basis for making managerial decisions by a farmer. It has been shown that the system of land capital management of farms should be based on the following basic principles: systematicity; purposefulness; balance of interests of a farmer, landowners, the state and society in the use of land resources; payment for land use; sustainable development of agricultural land use; rationality and economic feasibility of land use; priority of land protection as the main means of production; responsibility and information. The functions of land capital management of farms include planning of land capital use; forecasting of land capital use in the short, medium and long term; organization of land capital use; motivation and control of rational use of land capital.
