文摘Diverse evidence suggests that the sustainability of endorheic regions will be the underbelly of achieving the transformative promise“leave no one behind”of the Sustainable Development Goals(SDGs)proposed by the United Nations;for example,“Aral Sea Syndrome”[1],“basin closure symptom”[2],and saline lake salinization[3]are undermining life support systems and human wellbeing[4].Global warming is reducing the amount of solid water resources in mountainous regions[5],which,in turn,threatens the Asia water tower[6]that supports local life systems.
