Does rural land consolidation improve the environmental efficiency of grain production? A quasi-natural experiment based on China’s high-standard farmland construction policy
Published 2025-06-01“…A continuous difference-in-differences (DID) model is applied to examine the effects and mechanisms of the HSFC policy.ResultsThe study finds that: (1) the overall environmental efficiency of grain production in China is improving, although the rate of improvement diminishes from the eastern to the central and western regions; (2) the HSFC policy positively influences environmental efficiency, especially in the eastern region and areas with significant land transfers; and (3) the policy enhances efficiency primarily through the promotion of larger-scale farming operations and improved agricultural services.DiscussionThe findings suggest that the HSFC policy plays a key role in improving the environmental efficiency of grain production, particularly in regions with more advanced agricultural infrastructure. …”

Spatiotemporal Variation in Carbon and Water Use Efficiency and Their Influencing Variables Based on Remote Sensing Data in the Nanling Mountains Region
Published 2025-02-01“…Trend analysis, Hurst exponent analysis, and stability analysis were applied to examine the long-term patterns of CUE and WUE, while partial correlation analysis was employed to explore the spatial relationships between these efficiencies and climatic factors. The main findings of the study are as follows: (1) The CUE and WUE of the NMR decreased geographically from 2001 to 2023, and both the CUE and WUE of NMR showed a significant declining trend (<i>p</i> < 0.05) with the CUE decreasing at a rate of 0.0014/a (a: year) and the WUE falling at a rate of 0.0022/a. (2) The average values of the CUE and WUE of the NMR from 2001 to 2023 were 0.47 and 0.82 g C·m<sup>−2</sup>·mm<sup>−1</sup>, respectively, with a clear geographical difference. (3) The CUE and WUE in the NMR showed widespread degradation trends with some localized improvements, yet sustainability analysis indicates a likely continued decline across most areas, particularly for forests, while grasslands exhibit the greatest resilience. (4) Precipitation had a significantly stronger impact on WUE, while temperature appeared to exert a more substantial effect on CUE, with vegetation types responding differently; notably, shrubland displayed a direct association between CUE and temperature. …”
