Ladakh's Water Revival Plan Could Help Restore Tso Kar's Shrinking Wetland Ecosystem

At an altitude of around 15,000 feet in Ladakh, efforts are underway to revive Tso Kar, one of the region’s important high-altitude lakes, by redirecting glacier meltwater that would otherwise flow away through the landscape. The initiative is based on a relatively simple idea: Ladakh may face severe water shortages despite having substantial amounts of water locked in glaciers and seasonal snow. The challenge, according to officials and local communities, is ensuring that this meltwater is captured and used effectively. The approach seeks to restore the shrinking lake while also strengthening water security for communities, supporting wetlands and protecting the fragile ecosystem around the lake.

Former Delhi Lieutenant Governor V.K. Saxena, who is now associated with Ladakh’s water campaign, has been travelling through villages and remote settlements to understand local water requirements. He has argued that Ladakh’s status as a high-altitude cold desert makes its dependence on glacier and snow melt particularly important. Saxena said Ladakh has abundant water in the form of glacial and snow melt, but that the resource has not always been utilised optimally. The resulting imbalance, he said, has contributed to water shortages in the region. His campaign has focused on finding practical ways to capture and direct available water rather than relying only on large infrastructure projects.

The initiative has included interventions such as Him Sarovar, rock check dams and the channelisation of glacier runoff. These measures are intended to slow, store or redirect water so that it can remain available for local use and ecological needs for longer periods. The approach has emerged from discussions with villagers, who have identified water security as a priority for their communities. Rather than depending solely on large-scale construction, the projects seek to make use of natural terrain and relatively simple infrastructure. At Tso Kar, the same principle is being applied on a larger scale, with efforts focused on directing meltwater through natural depressions and other suitable routes towards areas where it can help replenish the shrinking lake and surrounding wetlands.

The condition of Tso Kar has become a major concern because of the dramatic reduction in its spread over the past decade. The lake once covered nearly 11,000 acres but has contracted to roughly 3,200 acres, representing a decline of almost 70 per cent. The retreat has transformed parts of the landscape, leaving behind wide, pale expanses where deeper water once existed. The reduction in water has implications beyond the lake itself. Tso Kar and its surrounding wetlands form part of a sensitive high-altitude ecosystem that supports wildlife and provides important habitat for migratory birds. A continued decline in water availability could therefore have consequences for biodiversity as well as for communities that depend on the surrounding landscape.

Among the species associated with the area is the black-necked crane, a migratory bird that has become an important symbol of Ladakh’s fragile wetland ecosystems. Shrinking wetlands can reduce the habitat and feeding areas available to such birds, adding pressure to an already sensitive environment. The decline of Tso Kar also affects local grazing resources. Pashmina herders depend on surrounding grasslands to support their livestock, making the condition of the lake and nearby wetlands closely connected to traditional livelihoods. Restoring water to the landscape could therefore have benefits that extend beyond the lake, helping sustain grazing areas and improving the availability of water within an environment where natural resources are limited and highly seasonal.

The effort to revive Tso Kar reflects a broader attempt to address Ladakh’s water challenge by working with the region’s natural geography rather than against it. Redirecting glacier melt through natural depressions and using low-energy structures could help retain more water within the landscape while supporting wetlands, wildlife, grazing lands and local communities. The initiative also highlights the unusual water paradox facing the high-altitude desert: water is being produced continuously through melting snow and glaciers, yet communities and ecosystems can still experience scarcity when that water is not captured or stored effectively. For Tso Kar, the hope is that directing part of this otherwise disappearing resource back towards the lake could help restore a landscape that has lost much of its water over the past decade.
