This Experiment Using a Glass Cover and the Sun Can Generate Water Even in Drought Affected Areas!

In a semi-arid region of Satara district in Maharashtra, there is a plot of lush green land with about 20 fully-grown, beautiful trees – all of which were the part of a very efficient experiment. The seedlings for these trees were fed with water obtained from dry soil, with the help of solar energy.
“I did my PhD in America way back in the late 1970s. And most of my work was around solar distillation of water. I looked at everything that could possibly be done with solar energy at that time and found that if you dig a small hole in the desert, and cover it with plastic, solar energy heats the soil and you can collect a cup of water every day. This was something that remained at the back of my mind for years,” says Dr. Anil Rajvanshi, Director of Nimbkar Agricultural Research Institute (NARI) – a non-profit research and development institute based in Phaltan, Maharashtra.
In 1981, Dr. Rajvanshi returned to India with the aim of using his education to work for the development of rural India, and started establishing the energy and sustainable development work at NARI.

“I came to this very dry and partially semi-arid region. Sometime in the 1980s, the Government of India conducted a very large-scale tree plantation program. But of the many seeds that were planted, only a few resulted in fully-grown trees. Most of the seeds perished,” he remembers.
