For over a century, experts - linguists, scientists and archaeologists - have tried to crack the Indus script.

Prevent conflict through international treaties and intergovernmental management of transboundary river basins -- for example, the Indus Waters Treaty between Pakistan and India, and Peru and Bolivia's joint governance of Lake Titicaca.

All three rivers—the Indus, the Ganges, and the Brahmaputra—originate in the region’s icy mountain ranges, where rapid warming is accelerating the melting of some glaciers and altering precipitation patterns.

This is a serious concern for the 750 million people in the Indus and upper Ganges basins who rely on these winter snows for water supplies.

For example, the Nile, Indus and Mississippi river basins have experienced exceptionally dry streamflow and wet soil moisture conditions, indicating changes driven by irrigation.
