Himalayan blunder in Uttarakhand
Policymakers need to actively engage with scientists to build a network of information based on land-use changes, hazard surveillance, weather monitoring and forecasting systems
The unfortunate disaster that struck Rishiganga-Dhauliganga Valley in early February is a sad reminder of the consequences of undermining the natural vulnerability of the Himalayas. We should not delude ourselves into believing that this is the last disastrous Himalayan event that caused losses to life and property, including two hydropower plants. In an article in
