Water, known as ‘Jal’ or ‘Pani’ in India, is fundamental to all living organisms. Whether it’s humans, plants, or other living beings, life cannot exist without water. It is the second most crucial element for life after oxygen (O2). Water makes Earth unique, and although 71% of our planet is covered by water, a large portion of it is not suitable for human consumption. This paradox of abundance and scarcity poses a significant challenge to the world, particularly to countries like India.

The Paradox of Water Availability
Despite the vastness of water on Earth, nearly 97% of it is non-potable, being saltwater from oceans, which cannot be consumed directly. The remaining 3% of water is fresh, but only a small fraction is readily accessible for human use. This small percentage of fresh water is found in rivers, lakes, ponds, and glaciers, but an even more crucial source is groundwater, which plays a vital role in providing potable water.
Groundwater: The Hidden Lifeline
Groundwater, stored deep beneath the Earth’s surface in aquifers, is a critical source of fresh water. It is trapped between layers of soil and rock, making it difficult to access without modern technology. Groundwater is essential for both rural and urban populations, as nearly 50% of India’s population relies on it for daily needs. However, this vital resource is depleting at an alarming rate.
The Growing Crisis of Groundwater Depletion
India is facing a severe water crisis, primarily due to the rapid depletion of groundwater. This issue is more concerning than the novel coronavirus in the long term, as it threatens the very survival of millions. Groundwater depletion is driven by various factors, including overexploitation for agriculture, industrial pollution, and inefficient water management practices.
The Extent of Groundwater Depletion
Groundwater accounts for 30% of the world’s fresh water resources, with 69% stored in ice caps, glaciers, and mountains, and the remaining 1% in rivers and lakes. In India, about one-third of the population relies on groundwater, and in some regions, up to 100% of water needs are met by this source. However, this lifeline is dwindling rapidly.
A report by the United Nations International Groundwater Resources Assessment Centre (UN-IGRAC) reveals that nearly half of the global population depends on groundwater for drinking. In India, groundwater is used predominantly for irrigation (67%), followed by domestic use (22%), and industrial purposes (11%). Despite its importance, the resource is being exhausted, leading to a tipping point that could result in severe global health and economic crises.
Factors Contributing to Water Scarcity
Water scarcity is not just a result of natural factors but is heavily influenced by human activities. Industrial waste, pollution, deforestation, and the overexploitation of natural resources have all contributed to the current crisis. Global warming and climate change are exacerbating the situation, leading to a drying Earth and worsening water scarcity.
Water Stress in India
India, with only 4% of the world’s freshwater resources, is home to the second-largest population. A significant portion of the population, nearly one-third, lives in water-stressed regions, and this number is expected to grow. The World Resources Institute (WRI) identifies India as one of 17 countries facing extremely high water stress. Reports indicate that in the last few decades, the demand for water-intensive crops like rice and sugarcane has led to increased reliance on groundwater, further depleting this resource.
Overexploitation in Indian States
Several Indian states, including Rajasthan, Punjab, and Haryana, are heavily overexploiting their groundwater resources, primarily for agricultural purposes. Rajasthan, largely a desert state, has minimal natural water sources and relies heavily on groundwater. Punjab and Haryana, known for their agricultural productivity, use groundwater extensively for irrigation, leading to rapid depletion.
Other states, such as Uttar Pradesh and Maharashtra, are also experiencing semi-critical levels of water stress. Even metropolitan cities like Bengaluru are facing overexploitation issues, with nearly 200 million people in India living in areas where groundwater usage is unsustainable.
The Impact of Groundwater Depletion on Agriculture
As an agrarian country, India relies heavily on groundwater for irrigation. The Green Revolution of the 1960s, which introduced new farming technologies, significantly increased the demand for groundwater. However, this has led to unsustainable practices, with groundwater levels plummeting as farmers dig deeper wells to access water.
The Economic and Social Consequences
The depletion of groundwater has severe economic and social consequences. According to a study published in the Journal of Environmental Economics and Management, as groundwater levels drop, farmers face increased costs to dig deeper wells or are forced to reduce the size of their farmlands. This leads to a financial burden on farmers, with increased electricity costs for pumping water from greater depths and the need for more powerful pipelines.
Additionally, water scarcity reduces agricultural productivity, leading to lower profits for farmers. In some cases, this has led to overwhelming debts and even suicides among farmers, particularly in the Deccan Plateau region. A report published in Third World Quarterly in 2013 highlighted the critical links between commercial crop farming, borewell failures, and farmer suicides in this region.
Climate Change and Its Effects
Climate change is further complicating the water crisis. While some studies suggest that rainfall in the Indo-Gangetic plains may increase by 2100 due to global warming, historical data shows that rainfall has actually decreased in recent years. This inconsistency adds to the challenges faced by farmers and the overall water management system in India.
Government Initiatives and Challenges
Recognizing the severity of the groundwater crisis, the Indian government has taken steps to address the issue. The Ministry of Environment, Forest, and Climate Change (MoEFCC) has formed an expert committee to recommend urgent measures and develop a long-term framework for sustainable water management. This includes regulating groundwater use in agriculture and promoting the use of sewage water for irrigation.
Regulatory Measures and Implementation Challenges
The expert committee has recommended that areas already overexploited for groundwater should not receive clearance for new environmental projects. They have also prepared a 50-year plan to manage groundwater resources sustainably. However, implementing these policies remains a significant challenge.
For instance, Tamil Nadu enacted the Tamil Nadu Groundwater (Development and Management) Act in 2003 to regulate groundwater use. However, the act was not implemented effectively, highlighting the gap between policy and practice. The failure to enforce regulations exacerbates the water crisis, making it essential for both the government and citizens to take action.
The Role of Citizens in Water Conservation
While government policies are crucial, individual actions also play a vital role in conserving water and protecting the environment. Since childhood, many of us have heard the slogan “Jal hi Jeevan hai” (Water is Life), emphasizing the importance of water conservation. Simple actions like turning off taps when not in use and reducing water waste can make a significant difference.
Natural Solutions for Groundwater Recharge
Plantation is one of the most effective ways to increase groundwater levels. Trees enhance the water retention capacity of the soil, helping to stabilize groundwater levels. Additionally, avoiding littering in water bodies like rivers and ponds and reducing the use of chemical fertilizers in agriculture can prevent water pollution.
Raising Awareness and Community Action
Educating others about the importance of water conservation and the dangers of groundwater depletion is another critical step. Organizing awareness campaigns and sharing information from credible sources, such as the United Nations and World Health Organization, can help communities understand the severity of the crisis and take action.
The Urgent Need for Sustainable Water Management
Water is undeniably the most precious resource on Earth, crucial for the survival of all living beings. The current water crisis, driven by groundwater depletion and pollution, poses a significant threat to India and the world at large. As the demand for water continues to grow, it is imperative that both the government and citizens take urgent action to conserve and manage this vital resource.
Sustainable water management practices, combined with effective policies and individual efforts, can help address the crisis. If we do not act now, the consequences will be dire, not only for our generation but for future generations as well. The time to act is now, and every drop of water saved today will contribute to a more secure and sustainable future.
