NEW DELHI, Oct 26 (PTI)
Some areas in the Indo- Gangetic basin in India have already passed the groundwater depletion tipping point and its entire north-western region is predicted to experience critically low groundwater availability by 2025, according to a new report by the UN.

Titled “Interconnected Disaster Risks Report 2023” and published by the United Nations University – Institute for Environment and Human Security, 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.
