Water scarcity and management have become pressing issues in urban areas across India, posing significant challenges to sustainable development and quality of life. Rapid urbanization, population growth, inadequate infrastructure, pollution, and climate change are exacerbating water woes in urban India.
A report by the NITI Aayog stated that around 2 lakh people die in India every year due to inadequate water supply. According to the World Bank, India has 18% of the world’s population, but only has enough water resources for 4% of its people. In 2023, around 91 million Indians will not have access to safe water.
Status
- In the 75 years since independence, the annual per capita availability of water has declined by 75%.
- Global Drought Risk and Water Stress map (2019) highlights that the major parts of India, particularly west and central parts of peninsular India are highly water stressed.
- Composite Water Management Index (2018) released by the NITI Aayog highlights the worst water crisis in the country, with more than 600 million people facing acute water shortages.
Water Woes Fuels Urban-Rural Tensions
As per the 2011 Census, 34% of India’s population resides in urban areas spread across 7,935 towns. Projections from the World Urbanization Prospects (2018) indicate that India’s urban population will surpass 40% by 2030 and hit 50% by 2050. The urban shift brings about a surge in water demand, with per capita water use in urban centers rising due to improved living standards. This urban growth mandates the sourcing of water from rural hinterlands, amplifying the allocation of water resources to urban areas at the expense of rural regions and agriculture.
The trend is particularly pronounced in cities relying on surface water sources, posing the potential for rural-urban conflicts. Climate change acts as an additional catalyst, aggravating the water crisis. Moreover, the majority of water in cities is often greywater, minimally recovered or reused, contributing to water pollution concerns. This complex interplay of urbanization, water demand, and climate change sets the stage for heightened tensions between urban and rural communities.
Key Factors Contributing to Water Woes in India
1. Variability in Rainfall Distribution:
India witnesses uneven rainfall distribution, with substantial precipitation occurring during the monsoon season. States like Kerala and Meghalaya receive excessive rainfall, while arid regions like Rajasthan and Gujarat face persistent water shortages. As of 2023, cumulative rainfall was 11% below the long-term average.
2. Over-exploitation of Groundwater:
Rampant groundwater extraction for irrigation, industry, and domestic use has resulted in aquifer depletion. The Central Ground Water Board’s report highlighted alarming overexploitation in states like Punjab, Haryana, and Tamil Nadu. Punjab’s groundwater in the first 100 meters is projected to be exhausted by 2029, and by 2039, the 300-meter depth will be depleted.
3. Inefficient Water Management Practices:
Inefficient water management, including wasteful irrigation practices, inadequate water storage, and poor maintenance of water sources, contributes significantly to water scarcity. According to the World Bank, over 50% of irrigation water is lost due to inefficiencies in India.
4. Urbanization and Industrialization Impact:
Rapid urbanization and industrial growth escalate water demand in cities and industrial zones. The Composite Water Management Index (CWMI) by NITI Aayog reveals that many Indian cities face water scarcity due to expanding populations and urban sprawl.
5. Water Source Pollution:
Pollution of rivers, lakes, and groundwater exacerbates water scarcity by compromising both quantity and quality. Major rivers like the Ganges and Yamuna face severe pollution issues, affecting water availability for various purposes.
6. Climate Change Influence:
Changing weather patterns and rising temperatures due to climate change disrupt water resources. Erratic monsoons, prolonged droughts, and altered precipitation patterns contribute to water scarcity. El Nino, associated with global warming, has become more frequent, reducing rainfall in India.
7. Inefficient Agricultural Water Use:
Outdated and wasteful irrigation practices in agriculture, coupled with water-intensive crops like sugarcane and paddy, contribute to inefficient water use. Government policies supporting crops with high water demands exacerbate the issue.
8. Inadequate Water Infrastructure:
Insufficient investment in water infrastructure, including storage reservoirs, canals, and treatment facilities, hampers the efficient management and distribution of water.
9. Population Growth Pressure:
India’s burgeoning population, expected to reach 1.7 billion by 2050, intensifies demand on the already limited water resources.
10. Weak Policy Implementation:
Weak enforcement of water conservation measures, groundwater regulations, and environmental laws impedes effective efforts to tackle water scarcity.
Addressing Water Scarcity: Strategies
1. Reduction of Overconsumption:
- Combatting water scarcity requires tackling excessive and inefficient water use across sectors. Leveraging modern technologies like IoT, AI, and remote sensing can facilitate more precise measurement and management of water consumption.
- For instance, farmers can utilize satellite monitoring to optimize irrigation based on weather conditions and local topography, leading to water savings and increased crop productivity. Prashant Maroo, a Chhattisgarh farmer, achieved a 20% crop yield increase and reduced water consumption through the implementation of IoT in his farm. Reforms in electricity subsidy policies are essential to complement these efforts.
2. Improvement of Water Efficiency:
- Enhancing the performance of water systems and infrastructure, including distribution networks, treatment plants, and storage facilities, is crucial in addressing water scarcity. Repairing leaks, minimizing losses, and upgrading equipment contribute to reducing water wastage and enhancing water quality.
- Organizations like UNICEF have successfully rehabilitated urban water distribution networks and treatment systems globally to decrease water leakage and contamination.
3. Expansion of Water Sources:
- Diversifying water sources through initiatives like rainwater harvesting, aqueducts, desalination, water reuse, and sustainable groundwater extraction can augment water availability for various purposes.
- Desalination, for instance, converts seawater into freshwater, addressing water needs in coastal areas.
4. Protection of Water Resources:
- Safeguarding and restoring natural resources like rivers, lakes, wetlands, forests, and soils is fundamental. These ecosystems play a crucial role in regulating the water cycle, filtering pollutants, preventing erosion, and mitigating floods and droughts.
- Wetland restoration, for example, enhances water quality and quantity by storing runoff and recharging groundwater.
5. Reforming Water Policies:
- Overhauling policies and institutions governing water management and allocation is essential. Clear rules, incentives for water use, fair pricing, and conservation measures need implementation.
- Stakeholder participation, cooperation, and the integration of water issues into broader development plans are crucial. Introducing policies that support less water-intensive crops can alleviate pressure on agricultural water use, necessitating a reevaluation of existing MSP regimes.
6. Utilizing Micro Irrigation Techniques:
- Adoption of micro irrigation practices, such as Drip and Sprinkler irrigation, not only reduces water consumption but also enhances productivity.
- According to the MS Swaminathan committee report on ‘More Crop and Income Per Drop of Water’ (2006), drip and sprinkler irrigation can save approximately 50% of water in crop cultivation and increase crop yields by 40-60%.
7. Implementing Buried Clay Pot Plantation Technique:
- A highly efficient method, buried clay pot irrigation, surpasses even drip irrigation. With a success rate of 90%, it proves particularly effective in saline soil and desert conditions.
- This ancient technique involves burying porous clay pots filled with water in the ground, gradually disbursing moisture to surrounding plants over several days. This method has demonstrated success in land restoration efforts in arid environments.
