Studies on land use structural optimization can support the sustainability of land resources. The Taipusi Banner lies in the arid and semiarid area of northern China, with rapid economic development and a vulnerable ecological condition. Taking the Taipusi Banner as a research case, we adopted a land use map and statistical data, and employed the ecosystem process model to establish five scenarios, including an economically optimal scenario, an ecologically optimal scenario, a comprehensively optimal scenario, a status quo, and a projected scenario. Based on multi-objective linear programming, the land use demand was optimized; then, the CLUE-S model and adaptability evaluation were adopted to establish spatial patterns. The ecological and economic benefits were then analyzed and policy suggestions are provided. The main results include the following: (1) The optimization outputs of various scenarios show that under optimization, cropland and forestland increased by 9.13% and 18.9%, respectively, and grassland decreased by 9.81%. (2) The land use optimization shows that comprehensive optimization aimed at achieving comprehensive benefits, ecological benefits, and economic benefits increased these benefits by 3.89%, 2.1%, and 6.2%, respectively. Compared with other scenarios, focusing on the comprehensive benefits of land use can result in the greatest increase in benefits to improve sustainability land resources. Land use optimization must consider not only the optimization of both the quantity and configuration but also the dimensions of both ecology and the economy. Land use should be based on a land suitability evaluation and optimization of the land use spatial configuration to update ineffective land uses and should gradually adjust both the ecological and engineering measures.

Land Use Optimization

The article presents modern literature data on the need to improve the development of agricultural lands, taking into account the current state of agriculture. Paying attention to this issue requires special attention, as it has acquired not only theoretical but also practical significance. Intensification of negative tendencies of anthropogenic influence on edaphotope lead to a number of ecological crises of global character. We analyzed the state of land use of Lviv region and reflected the main problems of land use optimization. The dynamics of changes that took place in the structure of the land fund by types of lands is shown. An extremely important component of sustainable development of society is the quality of life provided by the continuous development of environmental innovations. The destruction of the structure of the edaphotope of the region causes the emergence and development of environmental crises and catastrophes. Preservation of high potential and quality functioning of edaphos requires changes to the constant effective maintenance of balance, which should be based on the principles of sustainable harmonious development and rationalization of land resources. In terms of regions of aridity coefficients according to research, it can be argued that natural and climatic conditions have a direct impact on the efficiency of agricultural production. Such results require a review of technologies, their modernization and the development of recommendations for their adaptation. Resource-saving land use of new territorial entities in the post-reform period includes two factors – economic and environmental. For proper organization and optimization of land holdings, it is advisable to create agro-landscapes with a clearly planned structure, which should take into account the ratio of functional-territorial orientation, economic assessment and environmental safety. This means that the main and main goal of harmonious targeted use should take into account a number of indicators of the land use system, which requires special attention to agroecosystems in the interdependent close development of environmental and economic aspects. No less important is the environmental factor of land use, as further ignoring it can create economic collapse. In this regard, the most important requirement of the time is the development, improvement and widespread implementation of resource- and energy-saving, environmentally friendly farming systems. Ecological tolerance of certain territories of land resources should be laid down in the process of designing land management developments, paying special attention to the properties of landscape ecosystems, taking into account adjacent land plots. In particular, in order to preserve the balance of agricultural landscapes, it is necessary to implement a set of preventive measures.

A comprehensive undertanding of land-use/cover(LUC) change processes, their trends and future trajectories is essential for the development of sustainable land-use management plans. While contemporay tools can today be employed to monitor historical land-cover changes, prediction of future change trajectories in most rural agro-ecological landscapes remains a challenge. This study evaluated potential LUC changes in the transboundary Sio-Malaba-Malakisi River Basin of Kenya and Uganda for the period 2017-2047. The land use change drivers were obtained through a rigorous fieldwork procedure and the Logistic Regression Model (LGM) to establish key factors for the simulation. The CLUE-S model was subsequently adapted to explore future LUC change trajectories under different scenarios. The model was validated using historical land cover maps for the period of 2008 and 2017, producing overall accuracy result of 85.7% and a Kappa coefficient of 0.78. The spatial distribution of vegetation cover types could be explained partially by proximate factors like soil cation exchange capacity, soil organic carbon and soil pH. On the other hand, built-up areas were mainly influenced by population density. Under the afforestation scenario, areas under forest cover expanded further occupying 54.7% of the basin. Conversely, under the intense agriculture scenario, cropland and pasture cover types occupied 78% of the basin. However, in a scenario where natural forest and wetlands were protected, cropland and pasture only expanded by 74%. The study successfully outlined proximate land cover change drivers, including potential future changes and could be used to support the development of sustainable long-term transboundary land-use plans and policy.

The Relationship

Limited land resources are used to meet the growing economic, social, and ecological needs of people in China. Food, energy, and water (F-E-W) are the basic resources for supporting human survival and the transformation of different land uses. This paper tries to construct a theoretical framework of land use and the F-E-W nexus and uses system dynamics to simulate the optimal allocation of land use in Shizuishan City, China, by comparing different scenarios that have different parameters related to F-E-W. The final results follow: (1) according to the relationship between land use and the F-E-W nexus, a three-layer nested theoretical framework is constructed. (2) Future land use under different scenarios differs. Under the scenarios of a less dependence on coal energy, a higher utilization efficiency of energy and agricultural water resources, and a lower grain self-sufficiency rate, there are less crop and urban lands but more ecological land. However, generally speaking, crop and rural construction lands tend to decrease, while urban and ecological lands tend to increase. (3) Combined with different objectives, the rapid transformation scenario is considered a better option in which to achieve a balance among the economy, society, and ecology. This paper also discusses the application of land use optimization in the delineation of three control lines in territory-space planning in China.

Use Patterns

Climatic, socio-economic, geophysical, and human activity factors, among others, influence land use patterns. However, these driving factors also have different relationships with each other. Combining machine learning methods and statistical models is a good way to simulate the dominant land use types. The Luan River basin is located in a farming-pastoral transitional zone and is an important ecological barrier between Beijing and Tianjin. In this study, we predicted future land use and land cover changes from 2010 to 2020 in the Luan River’s upper and middle reaches under three scenarios—the natural scenario, the ecological scenario, and the sustainable scenario. The results indicate that cultivated land will decrease while the forested areas will increase quantitatively in the future. Built-up areas would increase quickly in the natural scenario, and augmented expansion of forest would be the main features of land use changes in both the ecological scenario and the sustainable scenario. Regarding the spatial pattern, different land use patterns will be aggregated and patches will become larger. Our findings for the scenario analysis of land use changes can provide a reference case for sustainable land use planning and management in the upper and middle Luan River basin.

Aim. To highlight the peculiarities of transformational changes in land use in agrarian production in terms of soil fertility and farming effi ciency in Ukraine. To carry out a comparative analysis of the effi ciency of use of land resources in different European countries. To substantiate approaches to farming biologization in conditions of intensifi cation of agrarian production and climate change. Methods. Observation, comparison, analysis and synthesis, system analysis and forecast. Results. The results of long-term fundamental and applied researches on the effect of intensifi cation of agriculture on the productivity level of agrarian production have been analyzed. A benchmarking analysis of the effi ciency of use of land resources in Ukraine and European countries has been carried out. It has been established that as a result of economic activity the basic principle of interaction between the agriculture and livestock sector was violated, which does not allow to combine ef- fectively and use the intensifi cation factors, the principle of fruit variability is not applied when introducing short crop rotations of the market crops. Conclusions. The effectiveness of agrarian production in conditions of transformational changes depends on the biological farming, which should be targeted at the rational use of land resources, prevention of degradation, preservation and enhancement of soil fertility and sustainable land use in time, use of life factors of agricultural plants taking into account their biological requirements.

Divergences in preferences over the allocation of rural land among stakeholders are getting stronger with the decrease of rural land area. This paper analyses the degree of divergences among different stakeholders over the allocation of four types of land: cultivated land, grassland, forest and other land, and explores the optimal allocation from the social perspective of balancing economic and ecological benefits. Considering the heterogeneity of stakeholders that are concerned with land-use decisions, we distinguish four types of stakeholders, namely, ecological authorities, economic authorities, herders and farmers. The diverging preferences of these four stakeholder types over the different types of land use were quantified using the Analytic Hierarchy Process. Weights for each stakeholder type were derived for three scenarios: equal weights, weights based on income distribution and weights based on labour force distribution. Welfare analysis was employed then to determine the individual optimal allocation by maximising the utility function of each stakeholder type. Social optimal allocation was derived by maximising the social welfare function, which is the weighted sum of individual utilities. Tai Pusi County, located in an eco-fragile area of northern China, was taken as a case to present the empirical analysis. Individual optima revealed the degree of divergences among stakeholders and the social optima revealed the optimal allocation based on social welfare. Our results provide policy insights on how to achieve an efficient allocation of rural land, balancing the ecological and economic benefits of different stakeholders from different types of land.
