This study analyzed Chinese companies’ behavior regarding corporate social responsibility (CSR) disclosure, and its impact on national and regional climate change measured by carbon emissions. CSR disclosure, supported by existing theories, is considered a powerful tool to curb climate change issues. We combined data of companies’ publicly traded annual financial reports and CSR reports from the China Stock Market and Accounting Research (CSMAR) database and provincial macroeconomic statistics from the Chinese National Bureau of Statistics to run panel regressions. The results verify the following: (a) China is in a relatively early stage of CSR development, and Chinese firms’ internal incentives to adopt CSR projects are low since none of the internal factors researched contribute to CSR disclosure. (b) External factors work slightly better for CSR practices, but at the same time, the CSR regulations still need further improvement. (c) The current CSR disclosure practices do not have a clear impact on carbon emission reduction, contrary to some predictions that CSR could help reduce carbon emissions.

In the new era of the rapid development of economic globalization and the community of human destiny, the implementation of the “One Belt and One Road” (OBOR) construction model is designed to coordinate environmental protection and economic development. Most of the countries along the Silk Road in the 21st century are developing countries, and the majority of them are facing the same ecological and developmental difficulties as China. In this paper, under the background of the “OBOR” strategy and on the basis of the distribution of global climate types, we selected Central Asia and Northwest China, which have temperate continental climates, as the research objects. We sorted out and summarized the main ecological problems faced by Western China and Central Asia during the development of the “Belt and Road” initiative. At the same time, in combination with the major ecological governance projects implemented in recent years, we proposed key ecological governance technologies that have a certain degree of scalability, such as key technologies for water resource utilization and protection, sand prevention and control, and saline-alkali land governance. The aim was to offer the experiences and a reference for providing technological models for the “one belt along the road” region and the country to build an effective ecological governance system. Two suggestions are then proposed for improving the feasibility and rationality of ecological governance technology in the construction of the “One Belt, One Road”. 1) With the implementation of the strategy of “OBOR” construction, the ecological threats the OBOR countries are facing cannot be ignored. Every country needs to jointly act to build an “OBOR” ecological civilization. 2) The participants must pay attention to the spatial heterogeneity and temporal dynamics of ecological carrying capacity, and provide data reference and support for the reasonable allocation of ecological governance technology.

Telecoupling interregional resource interaction based on cultivated land grain production (CLGP) plays a crucial role in ensuring national food security and advancing sustainable socio-environmental and economic development. Based on the provincial panel data of 31 administrative regions in China from 1990 to 2020, we used the spatial and temporal evolution of CLGP and the global Moran index to detect the spatial correlation of CLGP among the provinces in China; we adopted the SDM to study the telecoupling effect of CLGP among the provinces in China and decompose the effect, enabling us to propose policy recommendations for enhancing the telecoupling effect among the provinces. The results are as follows: (1) China’s inter-provincial CLGP has shown an increasingly strong telecoupling effect over time, further validating the scientific nature of China’s grain production pattern. (2) Cultivated land, irrigation area, the number of agricultural employees, the power of agricultural machinery, the proportion of grain sown, and total grain production have positive “flow” effects on spatial teleconnections between provinces and regions. (3) In terms of the total telecoupling effect, the most significant factor affecting CLGP is the ratio of the area sown with grain to the total area sown with crops. Meanwhile, the area of cultivated land in each region, the irrigated area, the agricultural labor force, the agricultural machinery total power, and the percentage of grain sowing in each region have the most direct telecoupling effect on CLGP. The conduct of the study further fleshes out the empirical research on interregional resource telecoupling linkages arising from resource deployment and utilization.

The spatial restructuring of rural settlements is conducive to the realization of rural transition and development. This study constructed a “point-line-surface” framework for the spatial reconstruction of the homestead in a typical mountain village and used the weighted Voronoi diagram and buffer analysis method to analyze. The results are as follows. (1) The development capacity of rural homesteads in Longfeng Village was divided into three levels: high, medium, and low. Among them, the high-level homesteads clustered in the north and south of the village in the form of a “T” and a long strip, respectively; the medium-level homesteads are mostly aggregated in the middle of the village; the low-level homesteads are mainly distributed along the Fenghuang Mountain. (2) The layout of homesteads in Longfeng Village was axis-oriented, which is manifested by the number and scale being in a gradient-decreasing pattern with the main road axis as the centerline. (3) According to the principle of “maximum” development capacity of the homestead, nine reconstruction units are divided. By calculating the location entropy, it is found that the dominant functions of each reconstruction unit mainly include supporting life services, operational production, ecological agricultural production, and traditional agricultural production, and there are obvious differences in the development patterns of homesteads in different functional units. (4) Based on the “point-line-surface” characteristics of the homestead, four reconstruction modes, namely, modern community type, field and garden integration type, road-pointing type, and traditional residential type, are summarized, and the reconstruction strategies are proposed accordingly. The “point-line-surface” framework of rural settlements is of practical significance and theoretical value, which can provide a decision-making reference for the optimization and reorganization of residential land space in villages of the same type in mountain areas. Moreover, the integrated and innovative framework proposed in the paper has also international significance, thanks to the possibility of replicating the research strategy and methodological approach in other contexts.

Cropland abandonment (CA) is a critical environmental issue globally, with balancing food security and ecological protection vital for sustainable development. This study explores CA behavior differences and drivers between out-of-poverty farming households (OPFHs) and non-poverty farming households (NPFHs) in China′s mountainous areas, using stepwise regression on survey data from 321 households in Liping County, Guizhou. The results show that: (1) The differences in CA behaviors between the two types of farming households are mainly reflected at the farmer level and the plot level. Plot integrity is a common influencing factor of CA areas for both types of farming households. (2) The driving factors affecting the area of CA by OPFHs also include the average age of the labor force, the proportion of the resident population in the total household registration population, and plot type, while the drivers affecting the area of CA by NPFHs include per capita income, non-agricultural income, per capita cropland area, and commuting time. (3) The differences in CA behavior and its driving factors between OPFHs and NPFHs in mountainous areas are characterized by diversity and interaction. Based on the results of the study, we propose the management of farming households and cropland, which can contribute to rural revitalization in China and the world, to a certain extent.
