Thirsting for Solutions: India’s Looming Water Crisis

India’s current water crisis is primarily driven by the below-average monsoon during June-August 2023. Data from the India Meteorological Department reveals that 42 percent of the country’s districts experienced below-normal monsoon rainfall during this period. In August 2023, rainfall across the country was 32 percent below the normal levels, with southern states experiencing an even more severe deficit of 62 percent. This year marked a historical low in August rainfall, the worst in the last 122 years since 1901.

The implications of this reduced rainfall are far-reaching. Agriculture, a significant contributor to India’s economy, is particularly vulnerable to the effects of a deficient monsoon. Crops depend heavily on adequate rainfall, and a prolonged deficit can lead to crop failures, reduced yields, and increased economic hardship for farmers. Moreover, the scarcity of water can extend beyond agriculture, affecting daily life and industries, thereby exacerbating economic challenges.

The Growing Water Demand

While India possesses the largest water resources in terms of irrigated areas globally, the demand for water has been steadily increasing due to changes in agriculture and industrial activities. As per data from the Ministry of Water Resources, the net amount of water that can be sustainably used in India annually is estimated at 1,121 billion cubic meters (bcm). However, projections indicate that the total water demand will reach 1,093 bcm by 2025 and a staggering 1,447 bcm by 2050. This forecast points to a severe water shortage in India within the next decade.

To contextualize the issue, it’s essential to use the Falkenmark Water Index, which measures water scarcity based on per capita water availability. According to this index, regions with per capita water availability below 1,700 cubic meters annually are classified as facing water scarcity. Shockingly, nearly 76 percent of India’s population already lives in areas with water scarcity. Tamil Nadu, a state consistently grappling with water scarcity, serves as a pertinent example. Even prior to 1990-91, water demand in Tamil Nadu exceeded supply. For instance, in 2004, the state’s total water requirement was 31,458 million cubic meters (mcm), while the supply was only 28,643 mcm.

State-specific Water Shortages

Tamil Nadu’s prolonged water scarcity is emblematic of the broader issue faced by many Indian states. The state’s challenges in meeting water demands stretch back over three decades and underscore the long-standing nature of the problem. It also serves as a bellwether for the need to address water scarcity systematically.

The intensification of economic activities, particularly in agriculture, has been a key driver of rising water demand. India’s agricultural sector currently utilizes approximately 85 percent of the country’s usable water. However, changing cropping patterns, introducing minimum support policies, and advocating for water-efficient irrigation methods are crucial strategies to mitigate this issue.

The Role of Climate Change

Climate change plays a pivotal role in India’s water crisis. The Intergovernmental Panel on Climate Change (IPCC) has consistently issued warnings about the rapid climate changes affecting rainfall patterns worldwide. In India, these shifts translate into reduced rainfall, both in terms of the number of rainy days and the volume of precipitation. This reduction in rainfall directly contributes to water scarcity, impacting not only human populations but also wildlife, livestock, and the environment.

Water scarcity is not solely a regional issue; it has profound implications for the global economy. The World Bank, in its 2016 report titled ‘Climate Change, Water, and Economy,’ underscores that countries facing water shortages are at risk of significant economic setbacks by 2050 if corrective measures are not taken.

The Consequences of Water Scarcity

The consequences of water scarcity are multidimensional and far-reaching. Beyond the immediate challenges of securing daily water supplies, water shortages can have devastating effects on various sectors. Environmental problems, such as dwindling biodiversity and habitat loss, can result from reduced water availability. Economic growth is also jeopardized, as industries and agriculture struggle to meet their water needs.

A notable case study is the severe water shortage experienced in Cape Town, South Africa, in 2018. Due to a prolonged drought, authorities were forced to ration water, limiting individuals to a mere 25 liters per person per day. Such situations can lead to immense public hardship and underscore the urgency of addressing water scarcity in India.

Addressing the Water Crisis: Proposed Remedies

Addressing India’s water crisis necessitates a multifaceted approach. Firstly, policymakers and communities must recognize the critical importance of water conservation, particularly during deficit rainfall periods. This change in mindset is fundamental to long-term water security.

Secondly, rainwater harvesting should be prioritized. States with a high number of tanks, such as Andhra Pradesh, Karnataka, Tamil Nadu, and Telangana, should invest in rejuvenating these water bodies. The Minor Irrigation Census data reveals that India has a total of 6.42 lakh tanks, lakes, and ponds. However, the 16th report of the Parliamentary Standing Committee on Water Resources, focusing on the repair, renovation, and restoration of water bodies, highlights a concerning issue. According to this report, most of these smaller water bodies are facing encroachment by both government and private entities. Furthermore, the First Census of Water Bodies, published by the Ministry of Water Resources in 2023, states that a staggering 38,486 water bodies across India have been encroached upon. Addressing this problem requires the implementation of stringent measures to remove these encroachments.

To reduce the strain on water resources, altering cropping patterns is imperative. Implementing policies that encourage farmers to shift away from water-intensive crops like paddy, sugarcane, and banana can significantly reduce water usage in agriculture.

The MS Swaminathan committee’s report on ‘More Crop and Income Per Drop of Water’ (2006) highlights the potential of drip and sprinkler irrigation. These methods can save approximately 50 percent of water in crop cultivation and increase crop yields by 40-60 percent. Identifying and promoting areas suitable for such micro-irrigation methods is crucial, especially in regions with severe water scarcity.

Water as a Valuable Commodity

As climate change continues to impact rainfall patterns, water is evolving from a public good into an expensive commodity. The changing pattern of rainfall, characterized by more frequent deficits, poses a significant challenge. To mitigate future water poverty, efforts should focus on storing water during periods of deficit rainfall.

In conclusion, India’s water crisis is a multifaceted challenge with dire consequences for its population, economy, and environment. Addressing this crisis requires immediate action and a holistic approach. Rainwater harvesting, changing cropping patterns, and proactive water conservation are essential steps. Recognizing that water is no longer a public good but a valuable and limited resource is crucial. By implementing these measures, India can work towards averting a future marked by severe water shortages and their devastating consequences.
