Study region: The Asian water tower (AWT) encompasses the Tibetan Plateau and adjacent mountain ranges. Study focus: The AWT serves as a key water supplier for China, yet its economic role has not been adequately quantified. To address this gap, we employ a hydro-economic model to quantitatively ass...
