Rajasthan's Groundwater Crisis Deepens Into Structural Emergency
Rajasthan's groundwater crisis has escalated into a structural emergency, with more than 70% of the state's assessed groundwater units now classified as overexploited. This alarming situation persists despite one of the wettest monsoon seasons in recent years, underscoring deep-rooted issues in water use and management.
Alarming Statistics from the Central Ground Water Board Report
The Central Ground Water Board's Annual Report for 2024–25, based on data from June 2024 to March 2025, reveals that 214 out of Rajasthan's 302 assessed groundwater units are overexploited. In these areas, extraction far exceeds recharge, leading to severe depletion. Only 37 units, or 12.25%, remain in the safe category, while 21 are semi-critical and 27 critical. These figures show little improvement from the previous year, reinforcing a worsening trend that demands immediate attention.
Record Monsoon Rainfall Fails to Alleviate Crisis
The scale of the crisis is particularly striking because it has continued despite unusually high rainfall. Rajasthan recorded 678.4 mm of rain between June and September 2024, which is 156% of its long-period average, making it one of the wettest seasons in recent memory. August alone saw the second-highest monthly rainfall in the state's recorded history. However, groundwater levels have not recovered, indicating a significant mismatch between rainfall and recharge.
District-Level Disparities Highlight Structural Weaknesses
At the district level, the mismatch is stark. Dausa, which received the highest rainfall in the state at around 1,409.4 mm in 2024, has all five of its groundwater blocks—Lalsot, Dausa, Bandikui, Sikrai, and Mahuwa—classified as overexploited. Similarly, Sawai Madhopur, the second-highest rainfall district with about 1,285 mm, has four of its six blocks in the overexploited category. These examples point to a deeper problem: heavy rainfall is not effectively translating into groundwater recharge, exposing structural weaknesses in water use and management practices.
Agricultural Dependence Accelerates Depletion
According to the report, nearly 85% of groundwater in Rajasthan is used for agriculture, compared with 14% for domestic use and 1% for industry. The state's heavy reliance on groundwater for irrigation, especially for water-intensive crops such as wheat, paddy, oilseeds, pulses, and sugarcane, is accelerating depletion in areas not naturally suited to such cropping patterns.
- In Ganganagar and Hanumangarh, canal-supported farming has expanded paddy cultivation.
- Parts of eastern Rajasthan continue to rely heavily on groundwater for wheat irrigation.
- In western districts such as Barmer and Jodhpur, even limited farming depends on deep borewell extraction, adding further stress to aquifers.
Visible Effects on Communities and Water Quality
The effects of this crisis are already visible across the state. In many villages and towns in Jodhpur, Barmer, Bikaner, and Jaipur, traditional wells have dried up, forcing residents to depend on deeper borewells or water tankers. Hemant Patel, secretary of the Resident Welfare Association of a prominent residential society in Jaipur, shared, "We have to depend on tanker water during peak summer as borewells no longer yield enough. It cost almost 2 lakh for fetching water every month from April till July."
Experts warn that the crisis is also affecting water quality. LK Sharma, Head of Environmental Science at Central University of Rajasthan, explained, "In several overexploited blocks, groundwater quality is deteriorating, with high salinity, fluoride, and contaminants like uranium and heavy metals making water unsafe without treatment."
Environmental and Climate Factors Exacerbate the Problem
Environmentalists emphasize that a strong monsoon cannot undo years of overuse. Praveen Mathur, retired Head of Department of Environment Science at MDS University in Ajmer, noted, "Recharge is slow and uneven, but extraction is continuous and rising. Once deeper aquifers are tapped, both quantity and quality decline."
Climate variability is worsening the situation. Sharma added, "While rainfall may be above average, its erratic distribution and high-intensity bursts limit effective recharge, with much of the water lost as runoff. At the same time, rising temperatures are increasing demand across agriculture and urban centres like Jaipur."
Urgent Corrective Steps Recommended
The Central Ground Water Board has called for urgent corrective measures to address this escalating crisis. Key recommendations include:
- Tighter regulation of groundwater extraction to prevent overexploitation.
- Expansion of micro-irrigation systems to improve water efficiency.
- Crop diversification away from water-intensive crops to reduce agricultural demand.
- Large-scale rainwater harvesting initiatives to enhance recharge.
- A shift towards surface water-based supply systems in critically affected regions to alleviate pressure on groundwater resources.
These steps are crucial to mitigate the structural emergency and ensure sustainable water management for Rajasthan's future.
