Southeast Asian ecological dependency on Tibetan Plateau streamflow over the last millennia
The great river systems originating from the Tibetan Plateau are pivotal for the well-being of more than half the global population. Our understanding of historical ranges and future changes in water availability for much of southeast Asia is, however, limited by short observational records and comp...

The great river systems originating from the Tibetan Plateau are pivotal for the well-being of more than half the global population. Our understanding of historical ranges and future changes in water availability for much of southeast Asia is, however, limited by short observational records and complex environmental factors.
