ABERDEEN University is working with partners to enhance an innovation to provide vital water in some of the planet’s most arid places.
The Ice Stupa, invented by engineer Sonam Wangchuk in Ladakh, India in 2013, is an artificial glacier used for storing winter water for use in the months when meltwater is scarce.
The Ice Stupa project has grown in the years since and has received international acclaim.
Frequent and extended droughts are threatening the life-sustaining crops cultivated in some of the coldest and driest parts of the world. The Cryosphere and Climate Change research group of the University of Aberdeen, in collaboration with the Jawaharlal Nehru University in New Delhi, has shown that “glacier shrinkage” in Ladakh, northern India, has increased at a dramatic pace over the last two decades.
For Ladakh, a “cold desert” with very little precipitations, the Ice Stupas have become a lifeline – providing essential meltwater to extend the otherwise very limited crop growing season by several weeks. They are built next to where the water is needed most, near fields.
They can release millions of litres of water each year, while the size and shape of the ice stupas make them particularly efficient, inexpensive, and easy to maintain.
However, the project is still in its infancy and more work is needed – from technical aspects such as ways to avoid water freezing in the pipelines, to a better understanding of local micro-climates and an improved distribution of water.
The University of Aberdeen, funded by the Scottish Funding Council, is working to establish a long-lasting collaboration with the local ice stupa team and academic colleagues in India to provide some of the answers to these questions.
Professor Matteo Spagnolo, of the University of Aberdeen’s Cryosphere and Climate Change Research Group, said: “Our research has shown that mountain glaciers in Ladakh are retreating at an increasing rate, and so it is clear that interventions such as Ice Stupas are essential.”
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
