UN report warns India heading towards groundwater depletion tipping point
New Delhi (PTI): Some areas in the Indo-Gangetic basin in India have already passed the groundwater depletion tipping point and its entire northwestern region is predicted to experience critically low groundwater availability by 2025, according to a new report by the United Nations.
Titled "Interconnected Disaster Risks Report 2023" and published by the United Nations University Institute for Environment and Human Security (UNU-EHS), the report highlights that the world is approaching six environmental tipping points: accelerating extinctions, groundwater depletion, mountain glacier melting, space debris, unbearable heat and an uninsurable future.
Environmental tipping points are critical thresholds in the Earth's systems, beyond which abrupt and often irreversible changes occur, leading to profound and sometimes catastrophic shifts in ecosystems, climate patterns and the overall environment.
Around 70 per cent of groundwater withdrawals are used for agriculture, often when above-ground water sources are insufficient. Aquifers play a crucial role in mitigating agricultural losses caused by drought, a challenge expected to worsen due to climate change.
However, the report warns that the aquifers themselves are approaching a tipping point. More than half of the world's major aquifers are depleting faster than they can naturally replenish. When the water table falls below a level accessible by existing wells, farmers may lose access to water, posing a risk to entire food production systems.
Some countries, like Saudi Arabia, have already exceeded the groundwater risk tipping point, while others, including India, are not far from it.
"India is the world's largest user of groundwater, exceeding the use of the United States and China combined. The northwestern region of India serves as the bread basket for the nation's growing 1.4 billion people, with the states of Punjab and Haryana producing 50 per cent of the country's rice supply and 85 per cent of its wheat stocks.
"However, 78 per cent of wells in Punjab are considered overexploited and the northwestern region as a whole is predicted to experience critically low groundwater availability by 2025," the report says.
Jack O'Connor, the lead author and senior expert at UNU-EHS, said, "As we approach these tipping points, we will already begin to experience the impacts. Once crossed, it will be difficult to go back. Our report can help us see risks ahead of us, the causes behind them and the urgent changes required to avoid them."

Karnataka govt directs municipal corps to regulate, prohibit pigeon feeding
Bengaluru (PTI): The Karnataka government has issued directions to municipal corporations across the state to regulate and prohibit feeding pigeons in public places, citing serious public health concerns.
Deputy Secretary to Government V Lakshmikanth has written to the Urban Development Department requesting it to issue directions to the Greater Bengaluru Authority (GBA) and all municipal corporations to take immediate steps to implement the measures.
In an official note dated December 16 issued by the Health and Family Welfare Department and released to the media on Wednesday, the department said uncontrolled feeding of pigeons in public places has resulted in large congregations of birds, excessive droppings and serious health concerns, particularly respiratory illnesses linked to prolonged exposure to pigeon droppings and feathers such as hypersensitivity pneumonitis and other lung diseases.

"The commissioner, the Greater Bengaluru Authority and the Commissioners and chief officers of other municipal corporations shall take necessary action to mitigate the causes of dangerous disease spread by pigeon and enforce specified guidelines in their respective jurisdiction," the note said.
According to the department, these include a prohibition on feeding pigeons or causing pigeons to be fed in areas where it may cause nuisance or pose a health hazard to the public. Pigeon feeding shall be permitted only in designated areas in a controlled manner, subject to certain conditions.
"The designated areas may be selected in consultation with stakeholders. The responsibility for upkeep of the designated areas and compliance to the directions shall be taken up by some charitable organisation or an NGO. The feeding in designated areas shall be permitted only for some limited hours in the day," it said.
The note further stated that authorised officers of local authorities shall issue on-the-spot warnings and may impose fines for violation of the order, or lodge complaints to prosecute offenders under Sections 271 (Negligent act likely to spread infection of disease dangerous to life) and 272 (Malignant act likely to spread infection of disease dangerous to life) of the Bharatiya Nyaya Sanhita.
It also directed local authorities to conduct public awareness campaigns, including the display of signboards, banners and digital messages, explaining the health hazards associated with pigeon droppings and feathers, the content of the regulatory directions and penalties for violations, and alternative humane methods of bird conservation that do not endanger public health.
