Environment and development are essential components in the process of human development, and the limitation of land necessitates rational use. To cope with the impact of urban expansion on the ...environment, in this study, the idea of anti-planning is examined. The ecosystem service function is considered a limiting factor, and it determines 28.94% of the land in the study area as the core eco-land area, setting it as the non-construction area. At the same time, future land use status of the study area in 2025 is determined by planning restrictions and multiyear land use predictions, and finally, optimal allocation of land in the study area is determined by using the FLUS(Future Land Use Simulation) model. The simulation results show that the ecological security pattern and landscape index of the city are optimised, fragmentation of the landscape has decreased, and aggregation degree has increased.
•Concept and classification system of eco-land.•Apply ecosystem service values to measure core ecological areas.•Combine “anti-planning” ideas with FLUS model.•Analyse optimization results with landscape index and LUCC.
In this study, we determined how farmers can be effectively encouraged to withdraw from their idle homesteads, in addition to revitalising the rural construction land stock and realising the ...market-oriented allocation of land resources. We constructed an evolutionary game model under three scenarios: without penalty mechanism; with a static penalty mechanism; and with a dynamic penalty mechanism. Further, we explicitly describe the strategic behaviours and dynamic evolution processes of local governments and farmers during withdrawal from their rural homesteads. According to the results of the evolutionary stable strategy, under effect of the dynamic penalty mechanism, the strategy systems formed by local governments as well as farmers can gradually converge and stabilise after short-term shocks, compared with that under the no penalty and static penalty mechanisms. Overall, the penalty mechanism mitigates the instability in the game process during participants' incremental changes and strategy choices, while the dynamic mechanism is optimal. Both static and dynamic penalty mechanisms influence the binary equilibrium strategies of local governments as well as farmers, and farmers' strategies evolve towards this state of withdrawal from their homesteads with increasing penalty. When the model is dynamically improved, the probability of farmers' withdrawal of their homesteads increases with increasing penalty. Thus, clearly, the establishment of a penalty mechanism can promote stability of the participants' system; higher penalty implies higher motivation for farmers to withdraw their idle homesteads, enabling revitalisation of the rural stock of construction land and promotion of the optimal allocation of land resource elements.
We quantified and evaluated the allocation of soil and water resources in the Aksu River Basin to measure the consequences of climate change on an agricultural irrigation system.
We first simulated ...future climate scenarios in the Aksu River Basin by using a statistical downscaling model (SDSM). We then formulated the optimal allocation scheme of agricultural water as a multiobjective optimization problem and obtained the Pareto optimal solution using the multi-objective grey wolf optimizer (MOGWO). Finally, optimal allocations of water and land resources in the basin at different times were obtained using an analytic hierarchy process (AHP).
(1) The SDSM is able to simulate future climate change scenarios in the Aksu River Basin. Evapotranspiration (ET
) will increase significantly with variation as will the amount of available water albeit slightly. (2) To alleviate water pressure, the area of cropland should be reduced by 127.5 km
under RCP4.5 and 377.2 km
under RCP8.5 scenarios. (3) To be sustainable, the allocation ratio of forest land and water body should increase to 39% of the total water resource in the Aksu River Basin by 2050.
This article is about the current agricultural scenario, where large‐scale production causes large amounts of food to be transported to various points of consumption, causing substantial emissions of ...so‐called greenhouse gases and increasing the carbon footprint. Land use optimization and land parcel allocation are essential areas of agriculture research that currently represent relevant challenges and are classified as combinatorial optimization problems. In this context, the Selection and Allocation of Land Parcels Problem (SA‐LPP) is proposed; its goal is to optimize the selection and allocation of land parcels with rectangular shapes in small areas available for food production. We propose a reformulation of the SA‐LPP as a variant of the two‐dimensional orthogonal packing problem (2OPP), called Group‐2OPP. This problem was solved through a Mixed‐Integer Linear Programming (MILP) model, but due to the model complexity, we also propose a Greedy Randomized Adaptive Search Procedure metaheuristic approach. Some sensitivity analyses were performed as well to evaluate the impact of parameters on the solutions. Computational results show that the proposed metaheuristic outperforms the MILP model in terms of solution quality and computational times.
Abstract
Large-scale artificial forests have replaced original land cover types such as arable land, garden land, evergreen broad-leaved forest, and Pinus khasya forest. In particular, the widespread ...introduction of Eucalyptus has caused great changes in land-use patterns and affected ecosystem service functions. How to rationally allocate land, improve the land utilization rate, and ecosystem service functions in a limited land area have become research hotspots. This paper mainly studies the land-use optimization in Lancang County, a large-scale eucalyptus-introduced region, by using the gray multiobjective dynamic programming (GMDP) model and the ant colony optimization (ACO) algorithm. The maximization of social, economic, and ecological benefits is used as the quantitative structure optimization objective in this model, while land-use suitability and spatial compactness are used as the spatial optimization rules. The results show the following: (1) The economic and ecological benefits are significantly improved after optimization compared with those of the current situation and the integrated land-use planning in Lancang County (i.e., the overall plan hereafter or the overall planning of land use by government departments). The social benefits are lower than those in the current situation and overall plan. (2) The suitability of the land-use spatial structure after optimization is improved to some extent compared with the land-use structures of the current situation and overall plan. In particular, the suitability of urban construction land is significantly improved after optimization. (3) The patch density (PD) index of each land-use type is significantly reduced after optimization. The fractal dimension (FRAC) indexes of urban construction land and natural reserves are increased compared with those in the current situation and in the overall plan. The compactness index (CI) of land use increases after optimization, and the degree of land-use fragmentation is improved significantly. (4) Land transfer is greater for arable land, garden land, forests, and natural reserves after optimization. Compared with the overall plan, more high-quality arable land and forest resources may be protected. In conclusion, optimized land use is conducive to promoting the rational use of land resources, socioeconomic development, and environmental protection in eucalyptus-introduced regions.
The issues of conducting forensic examinations on land management issues in the study of land management projects regarding the allocation of land plots with changes in their intended use are ...considered. The following regulatory acts regulating the issue of land plots with the change of their intended purpose and at present indicates the lack of the reference literature, methodology, methodological recommendations that would regulate the issues of conducting forensic expertise on land management projects regarding th e allocation of land with a change in their purpose appointment. It specifies the main tasks and necessary materials related to the possibility of conducting surveys of land management projects in relation to the allocation of land with a change in their intended use. The list of issues and their sequence are indicated, which are necessary for carrying out the full study of the relevant documentation on land management. The questions concerning composition, content and rules of registration of the corresponding normative and technical documentation on questions of implementation in land management are set. The main issues concerning the assignment (transfer) of land to one or another category of land, as an example, are disclosed in the classification (transfer) of the category of land - agricultural land to the category land of industry. The procedure for granting land plots with change of their intended purpose, coordination of documentation with the land management by the relevant services, competent for the approval of the land management project and land plots provision. The attention is drawn to the presence of a conclusion of the state examination of land management documentation on the produced documentation of land management and its obligation in accordance with the norms of legislation. This method and approach will enable full conduct of forensic examinations on land management issues in the study of land management projects for allotment of land plots with a change in their intended purpose, which is the basis for the formation of conclusions of judicial examinations.

Este artigo analisa as divergências das informações fundiárias e ambientais da Amazônia Legal, disponibilizadas pelos diferentes órgãos e identificadas nos levantamentos realizados na Clínica de ...Direitos Humanos da Amazônia pelos estudantes bolsistas e voluntários da Graduação e da Pós-Graduação em Direito da UFPA durante o ano de 2016 e 2018. Objetiva-se compreender porque os órgãos fundiários e ambientais, nas esferas federal, estadual e municipal, apresentam informações conflitantes acerca das Unidades de Conservação, Terras indígenas e Territórios Quilombolas. Como conclusão, afirma-se que a ausência de um sistema integrado de gestão fundiária e ambiental, que facilite a circulação de informações intergovernamentais e auxilie na elaboração de políticas públicas capazes de atenuar os efeitos negativos do processo de ocupação da Amazônia Legal é um dos principais motivos para a existência de informações oficiais desatualizadas sobre a realidade amazônica. Dessa forma, reitera-se a necessidade de padronização, integração para o compartilhamento das informações fundiárias e ambientais da Amazônia.

This book is a case study of Vietnam's efforts to fight poverty using market-oriented land reforms. In the 1980s and 1990s, the country undertook major institutional reforms, and an impressive ...reduction in poverty followed. But what role did the reforms play? Did the efficiency gains from reform come at a cost to equity? Were there both winners and losers? Was rising rural landlessness in the wake of reforms a sign of success or failure?Land in Transition investigates the impacts on living standards of the two stages of land law reform: in 1988, when land was allocated to households administratively and output markets were liberalized; and in 1993, when official land titles were introduced and land transactions were permitted for the first time since communist rule began. To fully assess the poverty impacts of these changes, the authors' analysis of household surveys is guided by both economic theory and knowledge of the historical and social contexts. The book delineates lessons from Vietnam's experience and their implications for current policy debates in China and elsewhere.
