  • WE are living in a time of our planet’s history in which sustainable development is not possible without science, technology and innovation.
  • The densely populated food plains downstream of Asia’s mountain ranges depend heavily on mountain water, especially for irrigation — with 16 million hectares (mh) of agricultural land benefiting three billion people with food produced in its river basins.
  • The hydrological regime of the rivers makes the Indus basin most dependent on snow and glacial melt, with an estimated 40pc of total upstream flows coming from melt run-offs in contrast to the Ganges river basin, where estimated snow and glacial melt contribute only 10pc to the overall volume of the river’s streamflow.
