UN report highlights alarming findings about the state of environment, specifically focusing on India's Indo-Gangetic basin and the impending groundwater crisis.
The United Nations has issued a new report called the “Interconnected Disaster Risks Report 2023,” which is published by the United Nations University – Institute for Environment and Human Security (UNU-EHS). This report highlights some alarming findings about the state of the environment, specifically focusing on India’s Indo-Gangetic basin and the impending groundwater crisis. Let’s break down the key points from this report.
The Groundwater Crisis in India:
Some parts of the Indo-Gangetic basin in India are facing a severe groundwater problem. In fact, they have already passed the tipping point of groundwater depletion. The northwestern region of India is expected to experience critically low groundwater availability by 2025. This is a major concern for the country.
What Are Environmental Tipping Points?
Environmental tipping points are like critical thresholds in the Earth’s systems. Once crossed, they lead to abrupt and often irreversible changes in ecosystems, climate patterns, and the environment as a whole. These changes can have catastrophic consequences.
The Six Environmental Tipping Points:
The report identifies six global environmental tipping points:
1. Accelerating Extinctions: The rate at which species are disappearing from the planet is increasing, which disrupts ecosystems and can have devastating consequences.
2. Groundwater Depletion: Many areas are using up their groundwater faster than it can naturally recharge, which is essential for agriculture and drinking water.
3. Mountain Glacier Melting: Melting glaciers impact water resources and contribute to sea-level rise, which threatens coastal areas.
4. Space Debris: The growing amount of space debris poses a risk to satellites and space activities, which are vital for modern life.
5. Unbearable Heat: Rising temperatures due to climate change can lead to extreme heat events that are dangerous for human health and the environment.
6. Uninsurable Future: Increasing environmental risks can make it impossible to insure against certain disasters, which affects our ability to recover from them.
Groundwater’s Vital Role in Agriculture:
Around 70% of groundwater withdrawals are used for agriculture. This is especially important when above-ground water sources are insufficient. Aquifers, which store groundwater, are crucial in mitigating losses caused by drought. However, many major aquifers worldwide are depleting faster than they can naturally refill.
The Case of India:
India is the largest user of groundwater globally, surpassing the combined usage of the United States and China. In the northwestern region of India, specifically Punjab and Haryana, farmers depend heavily on groundwater to produce 50% of the country’s rice and 85% of its wheat. This region is in danger because 78% of its wells are overexploited, and the report predicts critically low groundwater availability by 2025.
The Urgency of Action:
Jack O’Connor, the lead author of the report, emphasizes the urgency of the situation. As we approach these tipping points, we’ll begin to experience the consequences. Once we cross them, it becomes extremely difficult to reverse the damage. This report serves as a warning, helping us understand the risks, their causes, and the urgent changes needed to avoid disaster.
