Drought in India has resulted in tens of millions of deaths over the course of the 18th, 19th, and 20th centuries. Indian agriculture is heavily dependent on the climate of India: a favorable southwest summer monsoon is critical in securing water for irrigating Indian crops. In some parts of India, the failure of the monsoons result in water shortages, resulting in below-average crop yields. This is particularly true of major drought-prone regions such as southern and eastern Maharashtra northern Karnataka, Andhra Pradesh, Odisha, Gujarat, Telangana and Rajasthan.

There is a good news for Indian areas prone to drought, the scientists in Tamil Nadu have devised a new system that can make seawater potable and safe to drink too. The amount of sea water purified per day in 6.3 million Litres. This heralds, relief for 13 states in India which are currently reeling under drought.


The system has been set up by scientists of Bhabha Atomic Research Centre (BARC) at Kalpakkam in Tamil Nadu. This was the place where they use waste steam from a nuclear reactor to purify seawater. The water is desalinated and is made safe and tastier to drink .

Several plants have been set up in West Bengal, Punjab, Rajasthan, said KN Vyas, Director of BARC, Mumbai. Several membranes have also been developed by BARC that can produce purified drinking water out of groundwater contaminated by uranium or arsenic, at a meager cost. The system uses pedal work to generate the energy required by the system to purify water . It turns dirty contaminated water into potable water.On his recent visit to BARC, Prime Minister Narendra Modi too, pedalled a bicycle that had a water purifier installed on it.

These scientists have also made several household water purifiers that are being marketed all over the drought-hit areas of, Maharashtra. These purifiers have thin membranes and special filters to separate contaminants.

The Abstract people appreciates the efforts and work of Scientists of BARC for producing such an efficient system that would actually help the country face the problem of water crisis.
