Linking Soil, Land, and Climate: Strategies for Sustainable Agriculture and Ecosystem Stability

Abstract

Environmental degradation in rural land systems arises from complex interactions among ecological stressors, socio-economic transitions, and policy legacies. This study applies the driver–pressure–state–impact–response (DPSIR) framework to analyze the interconnected dynamics of soil degradation, land-use transformation, and climate variability in Yan'an, a semi-arid region of China's Loess Plateau. Using a qualitative approach combining semi-structured interviews, document analysis, and field observations, the research identifies agricultural policy reforms, demographic shifts, and insecure land tenure as key drivers exerting pressure through slope cultivation and chemical input intensification. These pressures have degraded soil fertility and vegetation cover, leading to reduced crop productivity and heightened livelihood vulnerability. Institutional responses such as the Grain for Green program and local terracing efforts have yielded partial ecological recovery but introduced trade-offs including farmland loss and low-biodiversity monocultures. The study concludes that sustainable land management requires integrated, participatory, and context-specific interventions addressing both structural and proximate drivers. Findings provide a transferable framework for linking soil–land–climate interactions with adaptive agricultural and policy strategies in semi-arid environments.
