Q.India is well endowed with fresh water resources. Critically examine why it still suffers from water scarcity.

Body Analysis

Reasons for Water Scarcity in India

• Highly Uneven Spatial and Temporal Distribution: India's water resources are highly skewed. Spatially, the northern and eastern river basins (like the Ganga-Brahmaputra) are water-surplus, while the western and southern regions (such as Rajasthan, Gujarat, and the Deccan plateau) face chronic, natural water deficits. Temporally, over 80% of India's annual rainfall occurs within the four monsoon months (June to September). This creates severe water scarcity during the remaining eight dry months of the year.
• Over-Exploitation of Groundwater: India is the world's largest user of groundwater, extracting more than the US and China combined. Groundwater meets over 60% of agricultural irrigation and 85% of rural drinking water needs. Free or heavily subsidized electricity has led to uncontrolled tube-well drilling, causing a catastrophic drop in water tables, particularly in the agricultural heartlands of Punjab, Haryana, and western Uttar Pradesh. A report by the Central Ground Water Board (CGWB) warned that groundwater levels in major cities like Delhi and Bengaluru are depleting at alarming rates.
• Inefficient Agricultural Water Management: Agriculture consumes nearly 90% of India's freshwater. However, water-use efficiency remains extremely low due to the widespread practice of flood irrigation, which leads to nearly 60% water loss through evaporation and deep percolation. Furthermore, government procurement policies and subsidies heavily favor water-intensive crops like paddy and sugarcane in naturally water-scarce regions.
• Severe Pollution of Freshwater Sources: A vast portion of India's surface water is unfit for human consumption due to pollution. Untreated municipal sewage, industrial effluents, and agricultural runoff loaded with chemical fertilizers and pesticides are dumped directly into rivers like the Ganga and Yamuna. Additionally, geogenic contamination of groundwater with arsenic, fluoride, and heavy metals is a major crisis in states like Bihar, West Bengal, and Rajasthan, rendering existing water sources unusable.
• Rapid Population Growth and Urbanization: India's population of over 1.4 billion places immense per-capita pressure on water resources. Rapid, unplanned urbanization has led to the destruction of natural urban wetlands, lakes, and floodplains (which act as natural recharge zones). Cities like Chennai, Bengaluru, and Hyderabad have faced severe, highly publicized water crises in recent years due to over-extraction and the concrete paving of recharge areas.
• Impact of Climate Change: Climate change is altering the Indian Monsoon, making it increasingly erratic. The country is experiencing fewer rainy days but more intense, concentrated downpours, which lead to immediate runoff and devastating floods rather than groundwater recharge. This is accompanied by prolonged dry spells and rising temperatures, which accelerate evaporation losses from reservoirs.
• Inter-State Water Disputes: Water is a State subject in India, and river basins are shared across political boundaries. Intense political disputes over water sharing, such as the Cauvery dispute between Karnataka and Tamil Nadu or the Sutlej-Yamuna Link Canal dispute, prevent the implementation of integrated, basin-wide water management strategies, leading to water hoarding and wastage during lean seasons.
• Inadequate Water Storage Infrastructure: Despite high seasonal rainfall, India has a very low per-capita water storage capacity compared to countries like the US or China. Due to a lack of adequate check dams, farm ponds, and reservoirs, a significant portion of monsoon runoff flows directly into the sea without being utilized.
• Leaky Urban Distribution Networks: In major urban centers, municipal water supply systems are highly inefficient. It is estimated that 40% to 50% of treated municipal water is lost as "Non-Revenue Water" due to pipeline leakages, illegal pilferage, and poor maintenance.
