Kolhapur/New Delhi: “Overuse of fertilisers has contaminated our ground water”, said Rajendra Nad, 52, who farms millet, sorghum and groundnut, and lives in Jalgaon district’s Bhusaval. Fertiliser overuse is posing a grave threat to India’s freshwater sources.

Five years ago, when Ramakant Desai, 55, hired a drilling rig to sink a borewell to irrigate his maize fields, he struck water at 200 ft. Today, the rig must drill more than four times as deep to 900 ft.


This is a common story in Desai’s village of Gargoti in the southern Maharashtra district of Kolhapur.

In a country where 74 percent of farmland is not irrigated and water shortages are growing – a report by the EA Water consultancy warns India will become “water scarce” by 2025 – depleting groundwater levels add to an ongoing farm crisis. In recognition of groundwater declines, Finance Minister Arun Jaitley said his government would spend Rs 6,000 crore (almost $900 million) on “groundwater management”, but the details are unclear.

India draws more freshwater annually compared to any other country – 761 billion cubic meters per year for domestic, agricultural and industrial use, according to four-year (2011 to 2015) World Bank data. The scarcity has worsened because more than half of that water is now contaminated, mainly by industry and sewage, sparking diarrhoea, typhoid and viral hepatitis.

With larger population, China uses 28 percent less freshwater than India

A common argument is that India’s growing water use in inevitable. But China, with 1.4 billion people, uses 554.1 billion cubic metres of freshwater every year – that’s 28 percent less than India.

The consequence: India’s annual per capita availability of water fell 74 percent over 69 years, from 6,042 cubic metres in 1947 to 1,545 cubic metres in 2011, according to a government water policy report.

“The political economy of subsidies has resulted in unsustainable extraction and use of groundwater and eventually to its depletion,” said Ayan Biswas, a water-management expert. Farmers using cheap, subsidised electricity are encouraged to draw groundwater without restriction, he said.

Water depletion in rural India is a result of unsustainable agriculture practices such as farms in water-scarce regions with water-hungry crops like paddy, cotton and sugarcane.

Groundwater levels “critical” in nine states

In nine states – in south, west and central India – groundwater levels are now described as “critical”, according to a 2016 parliament committee report on water resources. “Critical” implies a stage where 90 percent of groundwater has been extracted, with a significant decline in recharge capability.

As of December 2015, of 6,607 units (blocks, mandals, talukas) assessed, 1,071 in 16 states and two in union territories, were categorised as “over-exploited”, which means 100 percent of groundwater has been drawn, with little chance of recharge.

Groundwater levels in India are now more critical than anywhere else on earth, IndiaSpend previously reported. More than half of India now faces what is called “high” to “extremely high” water stress, most across the fertile Ganga-Brahmaputra basin.

Tamil Nadu and Rajasthan have the most over-exploited blocks.

More than half of India’s groundwater is contaminated

The other aspect of the water crisis is contamination. Surface and groundwater are laced with fluoride, nitrate, arsenic and iron.

As many as 650 cities and towns lie along polluted rivers, which contaminate groundwater, according to the latest report of the Central Pollution Control Board.

“Poor environmental management systems” in industries lead to toxic and organic waste discharges of water, the report said. This has resulted in “pollution of surface and groundwater sources from which water is drawn for irrigation and domestic use”.

More than half of India’s groundwater is contaminated, according to the Central Groundwater Board report. As many as 276 districts have high levels of fluoride, 387 districts report nitrates above safe levels and 86 districts have high levels of arsenic, the report said.

On average, contaminated water caused 10 million cases of diarrhoea, 740,000 cases of typhoid and 150,000 viral hepatitis cases between 2007 and 2011, the groundwater board said.

Back in Jalgaon, Nad’s village is falling back on traditional methods to fight the crisis. “We are looking at reviving the watercourse, to water pooling,” he said. “Hopefully, these will provide water for drinking and crops during dry spells.” (Sandeep Pai, IANS)

South Korean game developer has introduced a new initiative for Battlegrounds Mobile India (BGMI) which will enable a new level of parental control via time limitations and OTP confirmation. The 'Game Responsibly' initiative will also show warning messages along with break reminders, game limits and more. "Every player, below the age of 18, needs to register a parent or a guardian before they start playing for the first time. An OTP will be sent to the registered person's number, post which the minor is allowed to play the game," the company said in a statement.

Some games can get intense and make players lose track of time. However, with timely break-time reminders, the developer has made sure players get the required downtime. These reminders will help them look up from their game and get back to real life, maintaining a healthy game-life balance. In addition, with a strict gameplay limit in place players below 18 years must not indulge in gaming for more than 3 hours per day. This automatically helps them treat gaming as an activity performed in moderation.

The brand has also set an in-game daily spend limit of Rs 7,000 that automatically stops them from overspending and overgaming. Krafton recently announced that it has removed 25 lakh accounts in just over a month to eradicate cheating on Battlegrounds Mobile India (BGMI). Since the last announcement, between October 1 and November 10, Krafton banned 25,19,692 accounts permanently and 7,06,319 temporarily. "The company has cleaned out most of the cheaters in the game, making BGMI a much more fun experience, and will continue to take whatever step is necessary to keep BGMI fair and fun," it claimed.

Proper assessment is done before deciding on the approach to the treatment plan.

The rise in air pollution, coupled with lousy lifestyle habits, is causing a spike in respiratory diseases. According to a Lancet report, the contribution of chronic respiratory diseases in India increased from 4.5 per cent in 1990 to 6.4 per cent in 2016. With respiratory issues on the rise, there is an increased demand for natural solutions to treat such issues. Instead of conventional medicine, people are turning to alternative medical therapies to find cures for ailments.

Common Lung Disorders

Bronchial Asthma
Bronchitis is a health condition that causes inflammation in the airways of the lungs. This leads to narrowing of the air pathways and excess mucus causes wheezing, coughing and difficulty breathing. It is a chronic condition that interferes seriously with daily life.
