    The 2001–2012 MODIS MCD12Q1 land cover data and MOD17A3 NPP data were used to calculate changes in land cover in China and annual changes in net primary productivity (NPP) during a 12-year period and to quantitatively analyze the effects of land cover change on the NPP of China’s terrestrial ecosystems. The results revealed that during the study period, no changes in land cover type occurred in 7447.31 thousand km2 of China, while the area of vegetation cover increased by 160.97 thousand km2 in the rest of the country.

    The spatial restructuring of village systems is an important means by which to promote rural revitalization. A large number of villages with small average areas bring great challenges to the implementation of the Rural Revitalization Strategy (RRS) in China. To promote the implementation of the RRS, it is necessary to restructure the village system. This paper proposes a method of spatial restructuring for the village system at the county level, oriented toward the RRS. This study proposes a village classification system with central villages, characteristic villages, and merged villages.

    Understanding the impact of changes in cultivated land in terms of structure, distribution, and quantity on grain production potential (GPP) is essential for a sustainable land utilization strategy and food security. Cultivated land balance (CLB), as a critical policy aiming at protecting farmland in China, has greatly restricted the loss of cultivated land. However, changes in cultivated land were largely generated due to the land-use activities led by the CLB policy.

    Due to water scarcity, which is worsening due to climate change, rural areas often face the challenge of rural exoduses. Limited water resources restrict local farmers as the opportunities for cultivation in the fields are reduced. This makes rural areas increasingly unattractive. To strengthen rural areas, sustainable water management with a focus on water-reuse is required. Since treated wastewater is a daily resource with calculable quantities available, reused water can contribute to the sustainable strengthening of a region.

    Most election pledges require a significant budget for their implementation. In the case of a candidate for the head of a local government who presented his pledges related to urban planning by subdividing them into voting districts, we tested how the size of the budget committed to the voters affected the votes. Based on the urban planning-related pledged budget, the economic utility value of one vote was estimated to be about 2050 USD.

    Environmental regulation is an important means of restraining enterprises and protecting the environment. Rationalization of environmental regulatory policies can promote high-quality regional economic development. The optimization and upgrading of the industrial structure has an intermediary effect on the impact of environmental regulations on the high-quality development of the regional economy.

    Coupled with rapid urbanization and urban expansion, the spatial relationship between transportation development and land use has gained growing interest among researchers and policy makers. In this paper, a complex network model and land use intensity assessment were integrated into a spatial econometric model to explore the spatial spillover effect of the road network on intensive land use patterns in China’s Beijing–Tianjin–Hebei (BTH) urban agglomeration.

    The urban sprawl process of Ulaanbaatar has changed dramatically due to population growth. Ulaanbaatar city land management master plan defined the settlement zone area suitable for living as 33,698 ha. However, due to unrestricted urban sprawl caused by the exponential growth of the city’s population, the settlement zone area reached 39,235 ha, which exceeds the limit by 5537 ha. In order to tackle this issue, several urban planning concepts were developed to be implemented within Ulaanbaatar city urban planning framework.

    Local commons are underutilized in resource management models, thus limiting the effectiveness of the commons concept. This study examined the actual situation of the local commons in Altanbulag soum, a suburb of Ulaanbaatar City, Mongolia, where land degradation is a concern, using the case study method. Interviews using semi-structured questionnaires were conducted with pastoralists. It investigated land use and pastoralists’ relationships to open-access summer pastures, summer camp selection, grazing practice, and acceptance of migrants.

    In recent decades, a new paradigm on the rational and careful use of land as a non-renewable resource has arisen. This definition requires new management methods based on the application of the “CLORPT” equation (state factor model) (CL—Climate, O—Organisms:living beings, R—Relief (topography), P—Parent material. T—Time. Thus, factors that we determine, as well as the impacts of planning, are analysed. We have used the factor model CLORPT (is an instrument by which any planning model can be analysed and diagnosed (e.g., planning carried out in the Ordesa National Park (Huesca-Spain)).
