Telangana’s groundwater extraction rate of about 47% may suggest relatively low stress, but experts say the figure can conceal serious drought vulnerability in a state where hard-rock aquifers hold limited reserves. The concern is especially significant as El Niño conditions raise the risk of deficient rainfall, lower recharge and declining borewell yields. The issue is not only how much groundwater is extracted, but how much water the underlying aquifers can store and release when the monsoon fails.
That distinction exposes a wider weakness in the way drought risk is understood. India’s drought assessment framework, revised over time and expanded in 2020, uses several indicators, including rainfall, soil moisture, vegetation, cropped area, groundwater, reservoir levels and stream flows. Groundwater is therefore already part of the assessment. The concern raised by experts is that the same groundwater indicator cannot be interpreted uniformly across states with sharply different geological conditions.
For Telangana, the central question is whether a low extraction percentage is being treated as a proxy for resilience when the state’s aquifers may have limited capacity to absorb a prolonged rainfall deficit. The answer affects agriculture first, but it also has consequences for rural settlements, drinking-water security, local public administration and the reliability of borewell-dependent infrastructure.
Telangana’s geology is important because much of the state is underlain by peninsular hard-rock aquifers. Similar formations are found across Andhra Pradesh, Karnataka and Maharashtra. Unlike aquifers with larger and more continuous storage, hard-rock systems can have limited reserves and may respond quickly to changes in rainfall and recharge. A single poor monsoon can therefore produce a sharper impact than a statewide extraction figure might indicate.
Agricultural scientist GV Ramanjaneyulu told the Times of India that groundwater extraction has to be viewed alongside geological characteristics. The comparison with other states illustrates why extraction percentages alone can be misleading. Punjab extracts around 156% of its annual extractable groundwater, Rajasthan 147% and Haryana nearly 137%, while Telangana’s rate is about 47%. These figures show the intensity of extraction, but they do not by themselves reveal how aquifers will perform during a prolonged period without adequate recharge.
A lower extraction rate can indicate lower pressure on available resources. It does not necessarily show that an aquifer can supply water for an extended period after rainfall declines. Agricultural economist Ravi Kanneganti made this distinction in the report, noting that the percentage does not necessarily establish how much water an aquifer can provide during a prolonged rainfall deficit. In hard-rock regions, that difference can become visible through falling groundwater levels and reduced borewell yields before a conventional drought declaration captures the full extent of the problem.
The El Niño connection adds a seasonal pressure to an existing structural condition. Reduced rainfall can lower groundwater recharge, while agricultural pumping continues to support crops. If the deficit persists, the two pressures operate together: less water enters the aquifer and demand for irrigation remains. The result is not simply a rainfall problem. It is a mismatch between the timing of recharge, the storage characteristics of the aquifer and the water requirements of the cropping system.
Telangana already has a separate mechanism for tracking groundwater stress through its groundwater drought index. Figures cited in the report for July 2025 classified six mandals as facing extreme groundwater drought, three as severe, eight as moderate and 19 as mild. The remaining 585 of the state’s 621 mandals were categorised as normal. These numbers show that groundwater stress can be geographically concentrated even when the broad state-level picture appears stable.
That distribution is important for local governance. A statewide average can obscure the conditions of individual mandals where aquifers, rainfall patterns, cropping choices and borewell dependence combine to create higher risk. A normal classification across most mandals does not eliminate the need to identify the smaller areas where groundwater decline is already severe. It also does not establish that the normal areas will remain secure if rainfall deficits continue.
The experts’ argument is not to remove groundwater from India’s drought assessment framework. It is to interpret the hydrological component with greater precision. That would mean considering aquifer characteristics, recharge potential, groundwater trends and dependence on borewells alongside extraction rates. The proposed shift is from a single measure of pressure to a broader assessment of vulnerability.
This would also change the administrative purpose of drought monitoring. Instead of relying mainly on a seasonal assessment or a binary drought-or-no-drought decision, the system could be used as an early-warning mechanism. The suggestions reported include a baseline vulnerability score for every district and mandal, the combination of rainfall deficits with dry spells, soil moisture and crop stress, and regular updates during the agricultural season.
Such a framework would require different departments and information systems to work together. Groundwater conditions, rainfall, soil health, cropping patterns, crop stress, weather forecasts and field observations currently represent different parts of the rural water and agriculture system. The proposals would bring them together to identify risks before crop failure becomes widespread. Satellite data could contribute to the assessment, but the report also identifies the need to combine it with field observations rather than treating any single data source as sufficient.
The policy implications extend beyond water measurement. Experts suggested that drought management should account for dependence on water-intensive crops, farm debt and wider economic vulnerability. These factors determine how severely a rainfall deficit is experienced by farming households. Two mandals with similar rainfall or groundwater readings may face different consequences if their cropping patterns, credit exposure and access to alternative water sources differ.
The proposed use of graded risk levels would similarly move the system away from a single declaration. Extreme, severe, moderate and mild groundwater drought classifications already appear in Telangana’s groundwater drought index. The broader suggestion is to connect these levels to early interventions, including contingency crops, seed support, water conservation measures and credit assistance before crop failure occurs.
This approach places emphasis on timing. Once borewells fail or crops are damaged, government support becomes a response to loss. Earlier monitoring could instead trigger contingency measures while options remain available. The report does not establish whether such a fully integrated system currently exists, but it makes clear that experts see a gap between measuring groundwater stress and using that information to prevent wider agricultural distress.
The data also highlights the difficulty of applying national frameworks to different physical settings. A drought assessment framework that includes rainfall, soil moisture, vegetation, cropped area and hydrological indicators is broader than a rainfall-only system. Yet the meaning of each indicator depends on local conditions. Groundwater extraction has a different significance in a heavily exploited alluvial region than in a hard-rock region with limited storage capacity.
For Telangana, the unresolved question is whether the current weighting and interpretation of these indicators can detect stress early enough. The state’s 47% extraction rate does not answer that question. Nor does the fact that 585 of 621 mandals were classified as normal in the July 2025 groundwater drought assessment. Those figures describe current or recent conditions, but experts argue that they need to be read alongside aquifer vulnerability and the possibility of rapid deterioration after a poor monsoon.
The larger urban and regional issue is groundwater dependence. Although the immediate concern is agricultural distress, groundwater conditions shape the security of settlements, local economies and public services across the state. Where borewells are a major source of water, a decline in yield can affect households and institutions as well as farms. This makes groundwater assessment part of wider infrastructure and climate-resilience planning rather than a narrowly agricultural exercise.
The evidence supplied in the report confirms a specific warning: Telangana’s extraction percentage may understate its exposure to prolonged rainfall deficits because the state’s hard-rock aquifers have limited storage and can respond quickly to poor recharge. What remains to be established is how India’s drought framework will incorporate aquifer-specific vulnerability and whether the state’s groundwater drought index will be linked to timely support. The coming assessment of rainfall, groundwater trends and agricultural conditions will determine whether early-warning systems can identify stress before it becomes widespread distress.
