With the global climate becoming increasingly unpredictable, it is likely that water could become our most precious commodity not far in the future. Global warming is accelerating the melting of glacial reservoirs and snowpacks all around the world, and impacting the perennial rivers that flow out of them (Image1 and 2). Almost 1.3 billion people depend on the glacially-fed rivers from the Himalayas that are at risk of disappearing in the summer seasons. Countries have traditionally responded to water stress by either creating huge dams to hold back freely flowing surface water or turning to desalination from the ocean.
