Abstract Water plays a vital role in sustaining the natural functioning of entire ecosystem that supports life on Earth. It key roles well‐being society numerous ways. However, climate variability and land use cover (LULC) change have caused spatiotemporal water supply variation. Disentangling effects from LULC is crucial for sustainable resource management. The main purpose this study is, therefore, to disentangle relative contribution overall average annual Residual trends analysis combined with Integrated Valuation Environmental Services Tradeoffs (InVEST) yield model was adopted perform simulations impacts change. Ground satellite data were used study. area has experienced significant increasing wetness trend dynamics between 2003 2017. As result, an observed due joint watershed (203 mm). 94%, whereas contributes only 6% Climate negatively led variation while contributed positively 2010 Although ongoing soil conservation (SWC) practices improved vegetation retention watershed, driver Therefore, SWC should incorporate ecosystem‐based adaptation strategies scale up community‐based integrated management sustain supply.
