One day at a time for the glacier man

Chewang Norphel's work which was mentioned in 'Glacier man' Chewang Norphel seems to be getting more attention. There is a long article in Science (requires ubscription)Profile: Chewang Norphel: Glacier Man and a report in Hindustan Times A lonely struggle for the Iceman. From the Hindustan Times report:
"Earlier this year, Norphel finally received Rs 13 lakh from the Department of Science & Technology to build and maintain two glaciers for the next two years.

Another Rs 10 lakh for three more glaciers will come from the Indian Army in Jammu & Kashmir, under its people-friendly project Operation Sadbhavana (Good Intentions), which funds small-scale projects supported by local populations.

“It’s a simple concept that can be managed with local manpower and materials,” says Dr V.C. Goyal, a senior scientist and hydrologist with the Department of Science and Technology. “If it works, then it could be applied across various regions in the Himalayan belt, since there’s a tremendous water shortage across all these hilly regions due to the receding glaciers.”

The Department has now involved the Ladakh Autonomous Hill Development Council and respective village heads.

All small steps, but about time.

According to a United Nations Environment Programme report released in March 2008, trends in glacial melt suggest that the Ganga, Indus and Brahmaputra — which contribute more than 60 per cent of the water for all the rivers of India — may become seasonal as a consequence of climate change.

For Norphel, the solution is in taking it one day at a time.

“I am now building five more glaciers with the money I have received from the government,” he says, as he takes hurried steps across the brown mountains at a project site. “I’m also planning to train villagers with instruction CDs that I have made, so that I can pass on the knowledge before I die.” "
From the Science magazine article:
"A new climate threat
Norphel's glaciers are site specific—they require a certain altitude, water flow, and surface area temperature, so they are not suitable for every location, notes Andreas Schild, head of the International Centre for Integrated Mountain Development in Kathmandu. "Nevertheless, we are going to have to do some serious out-of-the-box thinking when it comes to sustainable water storage and investigate the efficiency of artificial-glacier technology," Schild says.

Norphel notes that he has already had interest in his glaciers from nongovernmental organizations working in Afghanistan and Turkmenistan. "In some areas, reservoirs are a much more practical solution," he says. "But in terms of water storage and release at the irrigation season, you can't beat artificial glaciers."

Despite his success, there has been little attention from the academic world. "I could do with some scientific help from specialists," Norphel says. "I am trying to collect data on how and where the glacier forms best, and which parts precipitate first and why, so that I can improve on them and people can use the technique elsewhere.

This September day, Norphel and his glaciers receive their first scientific visitor. Adina Racoviteanu, a geography graduate student at the Institute of Arctic and Alpine Research and the National Snow and Ice Data Center at the University of Colorado, Boulder, is passing through Stakmo en route to her glacier field stations farther east. When she offers to make Norphel a topographic map of the artificial glacier site using her hand-held GPS monitor, a $3000 device, his eyes light up. The pair spend the next several hours taking readings across the site, achieving what would take Norphel weeks to do with his tape measure and plumb line.

Later that day, as Norphel leaps nimbly across the boulders above Stakmo village, he points out his latest design tweaks. In 2006, when it rained for a week and the Zanskar River, which freezes over each winter, melted ahead of time, flash floods and landslides devastated his glacier here. "Blocking walls and canals were damaged by floods," recalls Norphel. "I'm still at the experimental stage, but I've been able to completely redesign this glacier site to make it withstand floods better.

The Stakmo site will soon have three artificial glaciers at increasing altitudes, so by the time the lowest one is spent, the one above it will have begun melting, and then the highest before the natural one at the top starts to liquidize. Norphel points out his latest seepage-avoidance technology: a 200-meter cement chamber that will be connected to the artificial glacier with 2- to 3-meter-long pipe. This will help distribute and freeze sheets of water evenly in the artificial glacier as well as providing a water reservoir for later in the year. "Creating the first such chamber is difficult in terms of design and funding," he says. "The rest will still be expensive but easy to replicate."

Money remains a huge problem. Norphel says that 75 other nearby villages are in suitable locations for his artificial-glacier technique, but he lacks funds, and what funds are promised do not typically arrive in full. The watershed development program allots $50,000 per project per village, but so far, only $12,000 has been released in two installments over the past 6 years.

And there's another problem: continued climate change. There is less and less snowfall during wintertime, when it is needed to contribute to Norphel's artificial glaciers. Instead, rain is arriving in September, ruining the harvests. It's a worrying trend. "These glaciers are not magic formations. They need that water over winter," says Norphel.

As the "retired" engineer makes his way up the mountain to his glacial work site, singing drifts up the valley from the villagers in the fields below, who are harvesting the last of this year's barley with simple scythes. It's a scene that must have played out for centuries. Without the Glacier Man, this village might well have fallen silent a decade ago."
