A tap in a Ladakh village was left running all winter. If you close it the water inside freezes, and the pipe bursts.
So it dripped all day, and the water pooled on the ground and turned into a sheet of ice.
A retired engineer sat in his garden looking at that ice, and worked out how to save the farms of Ladakh.
His name is Chewang Norphel.
He was born in Leh in 1935. He studied science at Amar Singh College in Srinagar and became a civil engineer with the rural development department of Jammu and Kashmir.
He worked there for about 36 years. He built roads, culverts, bridges, buildings and irrigation channels across Ladakh.
Then he retired, and the problem he had watched all his life was still there.
Ladakh gets almost no rain. It is a cold desert. Farming there depends entirely on water from melting glaciers.
The trouble is timing. The real glaciers sit very high up, so they only start melting properly in June and July. But a farmer has to sow in April. So the water arrives 2 months after it is needed, and then arrives in a rush nobody can use.
On top of that, the glaciers are shrinking. He has said the Stok glacier once covered half the mountain range he could see from his village. Now it is a thin cap at the top.
His idea came from the leaking tap.
If dripping water freezes into ice on its own, then water can be made to freeze on purpose, in a chosen place.
So he took the stream water that runs to waste in autumn and diverted it into a shaded side valley. He slowed it down with small check walls so it spread thin instead of rushing. Through winter it froze, layer on layer, into a sheet of ice.
The crucial part is where he built them. He put them low down the mountain, much lower than the natural glaciers. Lower means warmer, and warmer means it melts earlier.
So the water comes down in April, when the sowing happens.
He built about 15 of them. The biggest, at Phuktsey, is 1,000 feet long, 150 feet wide and 4 feet deep. It supplies water to a village of 700 people. It cost about 90,000 rupees.
Villagers carried the stone and cement up those slopes on their own backs to help build them.
Some villages that could grow 1 crop a year now grow 2. Potatoes and peas grow where they could not before, and those sell for more than barley. Young people who would have left for the cities have a reason to stay on the land.
He got the Padma Shri in 2015.
He has made one comparison more than once. India spends crores of rupees every day maintaining troops on the Siachen glacier. One day of that money, he says, could build 50 glaciers for the people of Ladakh.
Today, as every day, we remember Diogo Jota and André Silva, who tragically passed away one year ago.
Through immeasurable loss and incalculable pain, the impact they made and the legacies they left behind - not only within the footballing world, but in the hearts and minds of so many around the world - has shone through over the last 12 months.
All of our love, support, thoughts and prayers continue to be with Diogo and André's families, friends and all those whose lives were touched by them.
Forever in our hearts, forever our number 20 ❤️
Sadly, the day has come 💔 Mohamed Salah is the reason I fell in love with football, and Liverpool FC in particular. Can't put it in words how heart shattering it would be to not see you in Reds. The greatest ever the PL has ever seen
Thank you for everything the Egyptian King 👑
@anand_journo@ziyaussalam@BloomsburyIndia Enjoyed the entire program. In particular, your little anecdote of Mishra and Sharma being swapped regularly was fun to listen.
@cricdrugs If you were watching Liverpool vs Arsenal first half, then I'm feeling sorry for you. That has been one of the most boring 45 mints that anyone has seen.
