Reducing climate change-induced risks and vulnerabilities from GLOFs

About the project

The most significant climate change impact in Bhutan is the formation of supra-glacial lakes due to the accelerated retreat of glaciers with increasing temperatures. The risk of potential costly economic damages on key development sectors such as agriculture, hydropower, and forestry by Glacial Lake Outburst Floods (GLOFs) is mounting. Climate change is attributed as the primary reason that water levels in glacial lakes approach dangerous thresholds. This poses a new dimension to the existing range of threats to lives, livelihoods, and development.

Expected results

The project will demonstrate practical measures to reduce climate change-induced GLOF risks from the potentially dangerous Thorthormi glacier lake, and facilitate replication of the respective lessons learned in other high-risk GLOF areas, both within and outside Bhutan.

Complementary to this risk reduction effort, the project will ensure that early warning mechanisms for the Punakha-Wangdi Valley are expanded to incorporate coverage of this growing threat.

  • Improved national, regional and local capacities to prevent climate change induced GLOF disasters in the Punakha-Wangdue and Chamkar valleys 

    Reduced risks of GLOF from Thorthormi lake through an artificial lake level management system

    Reduced human and material losses in vulnerable communities in the Punakha-wangdue valley through GLOF early warning systems (EWS)
