Desertification is one of the most significant environmental and social challenges globally. Monitoring desertification dynamics quantitatively identifying contributions its driving factors are crucial for land restoration sustainable development. This study develops a standardized methodological framework that combines with mechanisms at pixel level, applied to northern China from 2000 2020. Using multisource data employing Time Series Segmentation Residual Trend analysis (TSS-RESTREND) method alongside geographical detector, we assessed reversion, expansion, abrupt change processes, along impacts interactions natural human were assessed. Over past two decades, proportion desertified decreased by 5.60%. Notably, 32.88% area experienced while only 5.86% underwent expansion. Abrupt changes in both reversed expanding areas observed, primarily central western regions, these concentrated periods 2009–2011 2014–2016. The various different sub-regions exhibited spatial heterogeneity. Increased precipitation, temperature, evapotranspiration contributed reversion area, wind speed influenced eastern area. Additionally, population density afforestation activities also promoted reversion. In contrast, precipitation increased temperature expansion areas, respectively, exacerbating this process. Overall, between enhanced. Future control ecological engineering planning should focus on coupling effects relevant vegetation changes.

Ecosystem services (ESs) are gaining increasing interest among researchers, local communities, and policymakers. The farming of Podolian cattle in the remote marginal areas southern Italy plays an important socio-economic role. This study aimed to assess perception ESs provided by Basilicata region actors stakeholders. Using a questionnaire administered 198 respondents, level agreement disagreement was assessed on 1–5 scale for four main ESs: cultural, regulating, supporting, provisioning. On average, related positive. However, role promoting tourism somewhat controversial, results terms regulation were divisive. provisioning had highly positive result. Further research is needed better understand region, providing more explicit guidance communities

ABSTRACT The crucial role of soil water retention and storage in hydrology the cycle is well established. However, sensitive degraded ecosystems like alpine meadows, effectiveness revegetation enhancing these critical functions remains understudied. This study investigates effects revegetating severely hillside meadows with artificial grasslands on capacity Qinghai‐Tibetan Plateau. Soil analyses at a depth 0–20 cm revealed significant improvements properties after revegetation, increases organic matter content (86.8%), total porosity (11.9%), capillary (31.6%), clay (13.5%). Both saturated hydraulic conductivity ( Ks ) field (FC) increased markedly, by 9.7% 63.7% upper layer (0–10 cm) 21.7% 69.6% lower (10–20 cm), respectively. Structural equation modeling identified bulk density, root mass FC, porosity, as dominant direct factors influencing path coefficients −0.56, 0.30, −0.53, 0.57, −0.12, respectively, while vegetation cover aboveground biomass were found to have indirect influences. These findings demonstrate that effectively improves regulating key physical properties. enhanced water‐holding has implications for understanding dynamics grassland establishment improving ecosystem health eco‐hydrological vulnerable environments. Furthermore, provides valuable insights theoretical basis developing ecological restoration solutions other regions.
