Evapotranspiration (ET) and water availability (WA) are critical components of the global cycle. Although effects ecological restoration on ET WA have been widely investigated, quantifying impacts multiple environmental factors plant consumption regional balance in dryland areas remains challenging. In this study, we investigated spatial temporal trends isolated contributions vegetation climate change to variations Beijing–Tianjin Sand Source Region (BTSSR) Northern China from 2001 2021, using remote sensing-based Priestley–Taylor-Jet Propulsion Laboratory (PT-JPL) model scenario simulation experiments. The results indicate that estimated was consistent with field observations state-of-the-art products. annual BTSSR increased significantly by 1.28 mm yr−1 primarily driven (0.78 yr−1) radiation (0.73 yr−1). contrast, drier led a decrease 0.56 ET. semiarid areas, were dominant driving variability ET, while arid relative humidity played more role. Furthermore, reduced precipitation resulted decline −0.91 during 2001–2021. Climate factors, rather than greening, determined BTSSR, accounting for 77.6% total area. These findings can provide valuable insights achieving sustainable ensuring sustainability resources under change. This study also highlights importance simultaneously considering assessing their negative availability.
