India experienced 3 major droughts in just 7 years between 2009 and 2016. 68% of India's cultivable area is vulnerable to drought, and over 500 million people depend on rain-fed agriculture. Yet students consistently fumble the basics of drought classification in UPSC answers. The three types of drought are not interchangeable, and the examiner knows when you are bluffing.
GS Paper 3 (2015) asked about disaster preparedness for drought. GS Paper 1 has tested climate classification and monsoon variability, which directly feeds into drought understanding. Get the fundamentals right.
Three Types of Drought: Stop Confusing Them
This is where most students lose marks. They use "drought" as a single concept. It is not.
| Parameter | Meteorological Drought | Hydrological Drought | Agricultural Drought |
|---|---|---|---|
| Definition | Rainfall deficiency below normal (less than 75% of long-period average) | Depletion of surface and subsurface water resources | Soil moisture inadequacy affecting crop growth |
| Key Indicator | Rainfall departure from normal | Reservoir levels, groundwater table, streamflow | Soil moisture index, crop stress indicators |
| Time Lag | Immediate (within the season) | Delayed (weeks to months after rainfall deficit) | Intermediate (depends on crop stage) |
| Primary Sector Affected | All sectors eventually | Drinking water, hydropower, industry | Agriculture, livestock |
| Response Mechanism | IMD monitoring, early warning | Water rationing, inter-basin transfer | PMFBY claims, MGNREGA employment, fodder supply |
| Example | 2015: All-India rainfall 14% below normal | 2016: 91 major reservoirs at 23% capacity in April | Marathwada 2015-16: Kharif crop failure across 5 districts |
Common student mistake: Writing "India faced a drought in 2015" without specifying type. Meteorological drought hit in 2015 (deficit monsoon), but the hydrological drought was worse in 2016 because reservoirs and groundwater had not recovered. Agricultural drought peaked during the Rabi season of 2015-16. One "drought event" has three different timelines. Show the examiner you understand this.
Drought-Vulnerable Regions
India's drought vulnerability follows a clear geographic pattern linked to rainfall reliability, soil type, and groundwater availability.
Rajasthan (Western): Receives less than 250 mm rainfall. The Thar Desert region faces chronic meteorological drought. Barmer, Jaisalmer, and Jodhpur districts are classified as “chronically drought-prone.” The Indira Gandhi Canal has partially mitigated drought in northern Rajasthan, but canal-tail areas still suffer.
Bundelkhand (UP-MP border): 13 districts across Uttar Pradesh and Madhya Pradesh. Rocky terrain with poor water retention. Bundelkhand faced continuous drought from 2004-2010, triggering massive distress migration to Delhi and Mumbai. Despite multiple "Bundelkhand packages" worth thousands of crores, groundwater tables continue to fall.
Marathwada (Maharashtra): Six districts including Latur, Osmanabad, and Beed. Rainfall is moderate (700-800 mm) but extremely erratic. In 2016, Latur had water delivered by train. The region's dependence on sugarcane, a water-intensive crop in a drought-prone zone, is a policy failure students should critique.
Rayalaseema (Andhra Pradesh): Anantapur, Kurnool, Kadapa, and Chittoor districts. Rain shadow region of the Western Ghats. Groundwater is overexploited, and the groundwater crisis here is among India's worst.
Kalahandi-Bolangir-Koraput (Odisha): The KBK region is chronically drought-prone despite being in a high-rainfall state. Poverty compounds vulnerability. Starvation deaths were reported from Kalahandi as recently as the 2000s.
Telangana (parts): Medak, Mahbubnagar, and Nalgonda face recurrent drought. Fluoride contamination of remaining groundwater adds a health dimension to the water crisis.
Manual for Drought Management 2016
The Revised Manual for Drought Management (2016) replaced the 2009 version and fundamentally changed how droughts are declared in India.
Key changes:
The 2016 manual introduced mandatory use of multiple indicators instead of relying solely on rainfall data. A state must now assess:
- Rainfall deviation (from IMD data)
- Dry spell assessment (consecutive weeks without rain)
- Remote sensing data (NDVI, vegetation condition index from ISRO)
- Soil moisture (using ISRO's satellite-based estimates)
- Hydrological indicators (reservoir storage, groundwater levels)
A drought is declared only when at least 3 of these triggers cross threshold values. This was a major improvement over the old system where state governments could declare drought based solely on rainfall data, often for political reasons.
Drought Declaration Process:
- State government initiates the process by assessing indicators
- State submits a Memorandum to the Centre requesting drought declaration
- Inter-Ministerial Central Team (IMCT) visits for ground verification
- Centre approves and releases funds from SDRF/NDRF
Common student mistake: Writing that the Centre declares drought. It does not. The state government declares drought. The Centre's role is to verify the declaration and release additional funds beyond the State Disaster Response Fund (SDRF). This distinction matters for federalism questions too.
MGNREGA as Drought Response
MGNREGA is India's most effective drought response mechanism. This is not an exaggeration. During the 2015-16 drought:
- MGNREGA employment demand spiked 36% in drought-affected districts
- 235 crore person-days of work were generated nationally
- Drought-hit states like Rajasthan, Madhya Pradesh, and Chhattisgarh used MGNREGA for water conservation works
The scheme works as drought response because:
- Demand-driven: Workers self-select when agriculture fails
- Wage security: Provides income floor during crop failure
- Asset creation: Drought-proofing works like farm ponds, check dams, and trenches
- Convergence: MGNREGA works can be converged with watershed development and PMKSY
The Supreme Court in Swaraj Abhiyan v. Union of India (2016) directed states to provide 150 days of MGNREGA work (instead of the standard 100) in drought-notified districts.
PMFBY and Crop Insurance
The Pradhan Mantri Fasal Bima Yojana (2016) replaced earlier schemes with lower premiums: 2% for Kharif, 1.5% for Rabi, 5% for commercial crops. Technology-based assessment using satellite imagery and drones was introduced.
Problems remain significant. Claim settlement delays average 6-8 months. Insurance companies have exited several states. And the fundamental issue persists: insurance compensates loss after the fact but does not prevent drought vulnerability.
The connection between drought and India’s air pollution crisis is underappreciated. Drought years see increased stubble burning as farmers rush to prepare fields with limited time, and dust storms from parched land worsen PM10 levels across northern India.
Watershed Development and Long-Term Solutions
Watershed development is the most sustainable drought-proofing strategy. The Integrated Watershed Management Programme (now subsumed under Pradhan Mantri Krishi Sinchayee Yojana) has treated over 28 million hectares.
Successful models:
- Ralegan Siddhi (Maharashtra): Anna Hazare's village transformed from drought-hit to water-surplus through watershed treatment
- Hiware Bazar (Maharashtra): Popatrao Pawar's model village increased groundwater by 5-6 metres through community-led watershed management
- Tarun Bharat Sangh (Rajasthan): Rajendra Singh's work revived 5 dead rivers through traditional johad construction
National Rainfed Area Authority (NRAA) was established in 2006 to coordinate development of rainfed areas. It advises on watershed management, rainwater harvesting, and drought-proofing. NRAA has prepared district-level plans for all drought-prone districts, though implementation varies wildly by state.
Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) with its "Per Drop More Crop" component promotes micro-irrigation. Drip and sprinkler irrigation coverage has increased from 8% to approximately 15% of irrigated area, but needs to reach 40%+ to make a real dent.
Understanding pressure belts and wind systems helps explain why certain regions face persistent rainfall deficits and why the monsoon fails in specific areas.
The Political Economy of Drought
Drought in India is not purely a meteorological event. It is a governance failure layered on a climate event.
Maharashtra grows sugarcane in Marathwada using 70% of available water for a crop that covers 4% of cropped area. Rajasthan promotes water-intensive wheat in arid zones. Punjab's free electricity for tube wells has crashed the water table. These are policy choices, not natural disasters.
The river interlinking project is often presented as a solution to drought. I am sceptical. Ken-Betwa Link, the only project making progress, has faced environmental concerns and tribal displacement issues. The idea that engineering can eliminate drought ignores the demand-side problem entirely.
