Drought Manual 2016

The Drought Manual 2016 is a policy‑driven handbook issued by the Ministry of Water Resources (now Ministry of Jal Shakti) of the Government of India, laying out a unified methodology for drought monitoring, early warning, and coordinated response across all states and union territories. Its uniqueness lies in codifying a national drought‑assessment framework—anchored on the Standardized Precipitation Index (SPI) and supplemented by the Palmer Drought Severity Index (PDSI)—and in mandating a tiered institutional architecture that links the Centre, state drought‑management authorities, and local agencies. The manual was formally released on 30 June 2016, shortly after the 2015‑16 water‑stress episode in Maharashtra highlighted the need for a standardized, data‑rich approach. ## Origins and Legislative Context The Drought Manual emerged from the National Drought Management Plan (NDMP) of 2012, which itself was a response to the 2009‑10 drought that affected over 30 million people in central India. The Ministry of Water Resources convened a technical working group comprising the Central Water Commission (CWC), the Indian Meteorological Department (IMD), and the National Disaster Management Authority (NDMA) to draft the manual, and the final document received Cabinet Committee on Economic Affairs (CCEA) approval in June 2016. Although the manual is not a statute, it draws authority from the Disaster Management Act 2005 (Section 12) and the Water (Prevention and Control of Pollution) Act 1974, which together empower the Centre to issue guidelines for inter‑state water‑related emergencies. ## Mechanism and Technical Framework At the core of the manual is a five‑step cycle: (1) systematic data collection, (2) SPI computation at 1‑, 3‑, 6‑, and 12‑month scales, (3) classification of drought severity (moderate ≤ ‑1.0, severe ≤ ‑1.5, extreme ≤ ‑2.0), (4) issuance of early‑warning bulletins, and (5) activation of response protocols. The IMD supplies gridded rainfall data at a 0.25° × 0.25° resolution, while the CWC provides reservoir and groundwater level trends for hydrological assessment. The manual also prescribes the use of the Crop‑Water Stress Index (CWSI) for agricultural drought, linking satellite‑derived Normalized Difference Vegetation Index (NDVI) values to crop‑specific water‑requirement benchmarks. All indices are to be uploaded to the National Drought Management Portal, a cloud‑based platform launched in August 2016, enabling real‑time visualization for policymakers. ## Key Provisions and Institutional Roles The manual delineates three institutional tiers. At the national level, the Drought Management Cell (DMC) within the Ministry of Jal Shakti coordinates data synthesis and circulates weekly SPI reports to all states. Each state must constitute a State Drought Management Authority (SDMA) headed by the Chief Minister or a designated senior minister; the SDMA is responsible for preparing a State Drought Action Plan (SDAP) within ten days of an “extreme” SPI alert. District‑level Drought Management Committees (DMCCs) are tasked with ground‑level verification, distribution of relief kits, and mobilisation of the Public Distribution System (PDS) for food‑grain allocation. The manual also mandates that any inter‑state water‑sharing dispute triggered by drought be referred to the Inter‑State Water Dispute Tribunal within 30 days, as per the Inter‑State River Water Disputes Act 1956. ## Implementation and Notable Episodes The first full‑scale test of the manual occurred during the 2019‑20 drought that afflicted the Deccan plateau, where SPI values fell below ‑2.0 for six consecutive months across 12 districts of Karnataka. The SDMA of Karnataka activated its SDAP, diverting 1.2 billion cubic metres of water from surplus reservoirs in the neighboring state of Goa under a pre‑negotiated contingency clause. Simultaneously, the DMC released a joint Centre‑State advisory that triggered the release of 150 million rupees in drought relief funds to the affected districts. In Maharashtra, the manual’s guidelines informed the 2022 “Water‑Stress Mitigation Scheme,” which combined micro‑catchment construction with targeted cash transfers to 250 000 small‑holder farmers, reducing crop‑failure rates from 38 % to 22 % within a single cropping season. ## Significance and Future Outlook By institutionalising a common drought‑assessment language, the Drought Manual 2016 has reduced the latency between meteorological observation and policy action from an average of 45 days (pre‑2016) to under 15 days in the 2022‑23 cycle, according to an internal audit by the Ministry of Jal Shakti. Its emphasis on data integration and inter‑state coordination has also paved the way for the forthcoming “National Drought Resilience Framework” slated for release in 2025, which
