Drought Management Manual

The Drought Management Manual (DMM) is a government‑issued operational guide that codifies the procedures for drought forecasting, mitigation, and response across India’s agricultural, water‑resource, and disaster‑management sectors. First published in February 2019 by the Ministry of Agriculture & Farmers’ Welfare, the manual translates the objectives of the National Drought Management Plan (NDMP) 2015‑2025 into actionable protocols, thereby linking meteorological early warnings with on‑the‑ground relief measures. Its distinctive feature is the integration of a three‑tiered institutional framework—national, state, and district committees—with quantifiable trigger points based on the Standardized Precipitation Index (SPI), enabling coordinated action that can be tracked against measurable water‑security outcomes.

Historical Background

The impetus for the DMM arose after the 2015–16 monsoon failure that left more than 30 million hectares of rain‑fed cropland water‑scarce, prompting the Ministry of Agriculture to request a dedicated drought‑response blueprint from the Ministry of Water Resources. The resulting NDMP, approved by the Cabinet on 12 December 2015, mandated the creation of a manual that would operationalise the plan’s strategic goals; the DMM was therefore drafted by a joint task force comprising the Indian Meteorological Department (IMD), the Central Water Commission (CWC), and the National Disaster Management Authority (NDMA).

The DMM builds on the Disaster Management Act 2005, specifically Section 6, which authorises the NDMA to formulate guidelines for natural‑disaster mitigation; it also aligns with the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) of 2015, which set a national target of 100 percent micro‑irrigation coverage by 2022. By embedding these statutory and programmatic references, the manual ensures that drought‑related interventions are legally anchored and financially supported through the central drought‑relief fund, which was expanded to Rs 1,200 crore in the 2020‑21 Union Budget.

Mechanism and Key Provisions

Forecasting under the DMM relies on IMD’s monthly SPI calculations, with moderate drought signalled when the three‑month SPI falls between –1.0 and –1.5, severe between –1.5 and –2.0, and extreme below –2.0. When two consecutive months register an SPI ≤ –1.0, the manual mandates that the State Drought Management Committee (SDMC) issue a Level‑1 alert within five working days, triggering pre‑emptive water‑budget adjustments.

Mitigation measures are codified in three strands: (1) water‑budget allocation, where each district must submit a deficit‑adjusted plan covering at least 85 percent of its net irrigable area; (2) crop‑insurance activation, whereby the Pradhan Mantri Fasal Bima Yojana (PMFBY) automatically raises premium subsidies by 20 percentage points for crops sown in declared drought zones; and (3) agronomic support, which obliges the Ministry of Agriculture to subsidise micro‑irrigation kits at Rs 2,500 per hectare and promote drought‑tolerant varieties such as Mahyco’s Dhanashakti.

Response coordination is executed through the SDMC, the District Drought Management Committee (DDMC), and the National Drought Management Authority (NDMA). The manual specifies that, upon a Level‑2 alert (SPI ≤ –1.5 for three months), the DDMC must mobilise Rs 50 crore of state‑level relief within ten days, while the NDMA releases an additional Rs 200 crore from the central pool for emergency water trucking and food‑grain distribution. Funding disbursement is tracked via the Integrated Drought Management Information System (IDMIS), launched in August 2020, which logs expenditures against predefined activity codes.

Implementation and Impact

Karnataka’s 2019 experience illustrates the manual’s efficacy: after the DMM’s Level‑1 alert in June 2019, the state’s irrigation department re‑allocated 12 billion cubic metres of water, cutting the irrigation deficit from 22 percent to 7 percent—a 15 percent improvement documented in the Karnataka Drought Review (December 2020). In Maharashtra, the 2021 deployment of drought‑relief kits under the DMM reduced reported crop loss from 12 percent to 2 percent across 4.5 million hectares, according to the State Agricultural Statistics Board. Gujarat’s 2022 groundwater extraction fell by 8 percent after the DDMC enforced a 30‑day moratorium on new borewell drilling, a change verified by CWC’s groundwater monitoring network.

The manual’s monitoring framework mandates an annual audit by the Ministry of Agriculture, which cross‑checks IDMIS data with satellite‑derived soil‑moisture maps supplied by ISRO’s Resourcesat‑2 mission. The 2023 audit revealed a 92 percent compliance rate among the 28 states, prompting the Ministry to issue a corrective action plan for the remaining 8 percent.

Looking ahead, the 2024‑25 revision of the DMM will incorporate climate‑projection scenarios from the Ministry of Earth Sciences, expand the trigger
