In an unprecedented move, India recently suspended the 1960 Indus Waters Treaty with Pakistan, citing cross-border terrorism. This was one of a series of escalations between the two countries which now find themselves on the brink of war.
The treaty suspension reflects a growing regional trend: South Asian countries are increasingly treating water as a strategic asset rather than a shared resource amid rising mistrust, climate stress and geopolitical competition.
The region is home to nearly a quarter of the global population, and relies on huge transboundary rivers fed by Himalayan glaciers – the so-called “Third Pole” of freshwater reserves. A breakdown in water diplomacy could trigger environmental collapse, humanitarian crises and geopolitical instability. The weaponisation of water must be urgently addressed as a global climate justice issue.
