Maharashtra Drought Declaration Highlights India’s Growing Water Stress and Need for Proactive Drought-Proofing

Recent Developments:

• The Maharashtra Government has declared 265 of 358 talukas drought-affected, covering about 74% of the state, following deficient monsoon rainfall and prolonged dry spells. The declaration was made under the state’s Drought Management Code, with Trigger-I conditions activated in the affected areas.
• The state has initiated measures including crop-loss assessment, crop-loan restructuring, land-revenue concessions, deferment of agricultural-loan recovery and electricity concessions for agricultural pumps. District authorities have also been directed to document crop damage using photographs and GPS coordinates.
• The development is significant because drought is no longer confined to traditionally arid regions; rainfall variability, prolonged dry spells, groundwater depletion, changing cropping patterns and climate change are increasing water stress across diverse parts of India.
• India supports nearly 18% of the global population with around 4% of global freshwater resources, making drought management central to food security, livelihood security, water security and sustainable development.

What is Drought?

Definition and Characteristics:

• Drought is a prolonged period of abnormally low precipitation that creates a water deficit relative to the requirements of ecosystems, agriculture, livestock, households and economic activities.
• Drought differs from an ordinary rainfall deficit because its impacts depend on rainfall distribution, soil moisture, groundwater availability, reservoir storage, cropping patterns and water demand.
• Therefore, drought should be understood as a multidimensional phenomenon involving interactions between climate, hydrology, agriculture and human water use.

Drought Scenario in India:

• The Drought Atlas of India demonstrates substantial spatial and temporal variability in drought occurrence across India, with drought frequency becoming more apparent when assessed at finer district and taluka scales.
• The severe 2002 drought illustrates the socioeconomic consequences of drought: around 56% of India’s area experienced moderate to exceptional drought conditions, affecting approximately 300 million people and 150 million cattle.
• Crop damage during the 2002 drought was associated with an estimated USD 8.7 billion economic loss and a 3.1% reduction in agricultural GDP, demonstrating that drought can generate economy-wide effects beyond agriculture.

Changing Nature of Drought:

• Historically, drought was primarily associated with arid and semi-arid regions, but changing rainfall patterns and rising water demand have expanded the geographical and socioeconomic dimensions of water stress.
• Even high-rainfall regions can experience seasonal water scarcity when rainfall becomes concentrated into short periods, surface runoff increases and groundwater recharge remains inadequate.
• Thus, annual rainfall totals alone cannot adequately explain drought vulnerability; rainfall timing, intensity, distribution and water-storage capacity are equally important.

Classification of Drought in India:

Meteorological Drought:

• Meteorological drought occurs when precipitation remains significantly below the long-term climatic average for a specified period.
• It is generally the initial stage of drought, and persistent meteorological drought can subsequently develop into agricultural and hydrological drought.
• Under the traditional Indian classification, a 26–50% rainfall deficiency is associated with moderate drought, while a deficiency exceeding 50% represents severe drought.

Agricultural Drought:

• Agricultural drought occurs when available soil moisture and rainfall become insufficient to meet crop water requirements, resulting in crop stress, reduced yields and crop failure.
• It depends not only on rainfall but also on soil characteristics, evapotranspiration, irrigation availability, crop type and the stage of crop growth.
• Agricultural drought therefore provides a stronger indication of the actual impact of rainfall deficiency on farm livelihoods and food production.

Hydrological Drought:

• Hydrological drought occurs when water availability in rivers, reservoirs, lakes and aquifers becomes insufficient to meet normal water requirements.
• It can develop even during periods of near-normal rainfall when water withdrawal exceeds natural replenishment, causing declining reservoir storage, river flows and groundwater levels.
• This makes groundwater over-extraction a major factor in converting temporary rainfall variability into persistent water stress.

How is Drought Declared in India?

Drought Assessment:

• Drought declaration is primarily a State Government responsibility, while the Union Government provides technical and financial frameworks for assessment and relief.
• The Manual for Drought Management, 2009 provides a framework for objective assessment using multiple indicators rather than relying exclusively on post-harvest crop assessment.
• States may use a combination of rainfall deficiency, sowing extent, vegetation condition and moisture availability to identify drought conditions.

Major Indicators:

• Rainfall Deficiency: Persistent rainfall deficiency during the monsoon can trigger drought assessment, particularly when seasonal and intra-seasonal rainfall falls substantially below normal.
• Area under Sowing: A substantial decline in the area sown with crops indicates inadequate soil moisture and farmers’ inability to undertake normal agricultural operations.
• Normalized Difference Vegetation Index (NDVI): NDVI derived from satellite observations provides information about vegetation health and can help identify agricultural stress over large areas.
• Moisture Adequacy Index (MAI): MAI compares actual water availability with crop-atmospheric water requirements and helps identify agricultural moisture stress.
• Ground and Crop Indicators: Modern drought assessment increasingly combines remote sensing with ground observations, crop conditions, reservoir levels and groundwater data to improve spatial accuracy.

Traditional versus Modern Assessment:

• Traditional systems such as annewari, paisewari and girdawari depend substantially on field-level crop assessment and post-harvest observations.
• Satellite-based indicators such as NDVI and MAI enable earlier identification of vegetation and moisture stress, allowing governments to move from post-impact assessment to anticipatory drought management.
• The most effective system is therefore a multi-indicator approach combining meteorological, agricultural, hydrological and remote-sensing information.

Legal and Institutional Framework:

Role of State and Union Governments:

• The State Government is the final authority for declaring an area drought-affected, while the Union Government provides national guidelines, technical support and financial assistance mechanisms.
• The Manual for Drought Management, 2009 and the NDMA Guidelines for Management of Drought, 2010 provide important reference frameworks, while states retain flexibility to account for regional agricultural and irrigation conditions.
• Drought management requires coordination among institutions responsible for agriculture, water resources, groundwater, disaster management, rural development and local governance.

Financial Relief:

• Immediate disaster relief is generally financed through the State Disaster Response Fund (SDRF).
• Where additional assistance is required after assessment, the Union Government may provide assistance from the National Disaster Response Fund (NDRF) according to applicable procedures.
• Effective drought management should not, however, reduce policy to compensation; relief must be combined with water conservation, livelihood protection and resilience-building measures.

Supreme Court and Drought:

• In Swaraj Abhiyan v. Union of India (2016), the Supreme Court addressed the obligations of the State in drought-affected areas and linked effective implementation of food-security measures with the protection of Article 21 rights.
• The case established an important constitutional dimension of drought management: prolonged drought can threaten access to food, livelihood and dignified living, requiring effective implementation of statutory welfare mechanisms.

Major Causes of Drought in India:

Meteorological and Climatic Causes:

• Erratic South-West Monsoon: Since a substantial share of India’s annual rainfall occurs during the monsoon season, delayed onset, prolonged monsoon breaks, uneven spatial distribution or early withdrawal can generate severe rainfall stress.
• El Niño–Southern Oscillation: El Niño can alter tropical atmospheric circulation and influence Indian monsoon behaviour, increasing the probability of rainfall deficiency in some years, although the relationship is not deterministic.
• Climate Change: Climate change can intensify hydro-climatic variability by increasing the likelihood of extreme rainfall events separated by longer dry spells, creating a paradox of floods and droughts within the same region or season.
• Rising Temperature: Higher temperatures increase evapotranspiration, thereby increasing crop and ecosystem water requirements even when rainfall does not decline proportionately.

Human-Induced Causes:

• Skewed Cropping Patterns: Cultivation of water-intensive crops such as sugarcane and paddy in water-stressed regions can increase pressure on surface and groundwater resources.
• Groundwater Over-extraction: India is highly dependent on groundwater for irrigation and domestic use, and excessive pumping can reduce aquifer storage and weaken the natural buffer against rainfall variability.
• Ecological Degradation: Deforestation, wetland destruction, soil degradation and encroachment of traditional water bodies reduce infiltration, groundwater recharge and landscape-level water retention.
• Inefficient Irrigation: Flood irrigation and inefficient water application increase water losses and reduce the amount of agricultural output generated per unit of water.
• Urbanisation: Increasing impervious surfaces reduce groundwater recharge while growing urban populations increase demand for water, intensifying competition between agricultural, domestic and industrial uses.

Key Challenges in Drought Management:

Delayed Declaration and Relief:

• Reliance on post-harvest crop assessment can delay recognition of mid-season agricultural stress, reducing the effectiveness of timely relief.
• Drought assessment must increasingly use near-real-time satellite, rainfall, soil-moisture, reservoir and groundwater information.

Fragmented Water Governance:

• Surface water and groundwater are often managed through different institutional structures, creating a fragmented approach to a resource that functions as an integrated hydrological system.
• The Mihir Shah Committee recommended restructuring existing institutions and proposed a National Water Commission for integrated water-resource management; subsequent government discussions have examined the proposed institutional restructuring.

Relief-Centric Approach:

• Drought responses frequently emphasise water tankers, fodder, compensation and loan relief after conditions deteriorate.
• Such measures are necessary during crises but cannot substitute for long-term investments in watershed development, aquifer management, crop diversification and drought-resilient infrastructure.

Limited Micro-Irrigation:

• Drip and sprinkler irrigation can improve water-use efficiency, but adoption remains constrained in several regions by initial investment requirements, fragmented landholdings, technical limitations and inadequate maintenance capacity.

Groundwater–Agriculture Nexus:

• Free or highly subsidised electricity can reduce the marginal cost of groundwater extraction, encouraging pumping beyond sustainable recharge levels in some regions.
• Drought policy therefore requires simultaneous reform of cropping incentives, irrigation pricing, groundwater regulation and electricity policy.

Measures Needed to Strengthen Drought Management:

Climate-Resilient Agriculture:

• Promote agro-climatic zoning so that crop choices correspond to local water availability, soil conditions and climatic suitability.
• Encourage diversification from highly water-intensive crops towards millets, pulses, oilseeds and other climate-resilient crops, supported by appropriate procurement, market access and value chains.
• Strengthen climate-resilient seed systems, contingency crop planning and weather-based agricultural advisories.

Water-Use Efficiency:

• Expand micro-irrigation, precision irrigation and water-saving agronomic practices under programmes such as the Pradhan Mantri Krishi Sinchayee Yojana.
• The principle of “Per Drop More Crop” should be linked with crop diversification so that efficiency gains do not simply encourage expansion of water-intensive cultivation.

Groundwater Governance:

• Move from individual well-based extraction towards aquifer-level groundwater management.
• Strengthen community participation through Gram Panchayats, Water User Associations and local groundwater budgeting.
• Experiences under the Atal Bhujal Yojana demonstrate the importance of community participation, groundwater measurement and water-use planning.

Watershed and Ecosystem Restoration:

• Restore tanks, ponds, johads, baolis, eris, wetlands and traditional drainage systems to improve local water retention and groundwater recharge.
• Promote watershed development through check dams, contour trenches, farm ponds, recharge structures and soil-moisture conservation.
• Integrate watershed programmes with rural employment programmes to generate both ecological assets and rural employment.

Technology and Early Warning:

• Strengthen satellite-based drought monitoring through systems such as National Agricultural Drought Assessment and Monitoring System (NADAMS).
• Integrate rainfall forecasts, soil moisture, NDVI, groundwater levels, reservoir storage and crop-condition data into a unified drought-monitoring platform.
• The NDMA’s SACHET platform demonstrates how geo-targeted, multi-hazard early-warning systems can disseminate government alerts in near real time.
• Early-warning systems should be connected to pre-agreed triggers for action, including fodder planning, drinking-water arrangements, crop advisories and livelihood support.

• Reform: Early warning + crop diversification + micro-irrigation + aquifer management + watershed restoration.
• Governance Principle: Shift from crisis relief to risk reduction and drought-proofing.
• Core Objective: Build water-resilient agriculture and communities rather than merely compensating for drought-induced losses.

Conclusion:

• Drought in India is not merely a rainfall-deficiency phenomenon; it is the outcome of interactions among climate variability, rising water demand, agricultural practices, groundwater extraction and institutional weaknesses.
• Maharashtra’s recent drought declaration demonstrates the need for early identification, targeted relief and long-term resilience-building.
• India’s drought strategy should therefore shift from reactive relief to proactive drought-proofing, combining climate-resilient agriculture, efficient irrigation, aquifer management, ecosystem restoration, scientific monitoring and community participation.
• Such an approach is essential for simultaneously protecting food security, livelihood security, water security and sustainable economic growth.
