On June 2024, the India Meteorological Department (IMD) projected monsoon rainfall at 88% of the Long Period Average (LPA), categorizing it as below-normal. This forecast is driven by a developing El Niño Southern Oscillation (ENSO) event, with the ENSO index at +1.26C, indicating moderate El Niño conditions (NOAA, June 2024). Historically, El Niño years such as 2009 and 2015 have coincided with 10-15% monsoon deficits, triggering drought-like scenarios across India. The IMD’s forecast underscores significant risks to agriculture, water resources, and rural livelihoods, demanding urgent policy and institutional responses.

El Niño and Its Impact on Indian Monsoon

El Niño is a periodic warming of the central and eastern Pacific Ocean that disrupts atmospheric circulation patterns. It weakens the Indian summer monsoon by altering the Walker circulation, reducing moisture transport to the subcontinent. IMD data shows that El Niño years typically record a 10-15% rainfall deficit, leading to drought conditions in vulnerable regions. The current ENSO index of +1.26C signals a moderate El Niño, likely to suppress monsoon intensity and distribution in 2024.

• El Niño reduces monsoon rainfall by disrupting ocean-atmosphere coupling (IMD, 2024).
• Historical El Niño years: 2009, 2015 – monsoon rainfall deficit of 10-15% (IMD reports).
• Monsoon deficit correlates with drought incidence and agricultural stress (NDMA Annual Report 2023).

Economic Implications of Below-Normal Monsoon

Agriculture contributes approximately 17-18% to India’s GDP and employs 42% of the workforce (Economic Survey 2023-24). A 10% rainfall deficit historically results in a 2-3% drop in agricultural output (IMD and NABARD). India’s foodgrain production, recorded at 316 million tonnes in 2023-24, faces risks from deficient monsoon. Water scarcity affects 54% of districts, intensifying irrigation challenges since only 49% of net sown area is irrigated (Agricultural Census 2020). Rural incomes, dependent on monsoon-linked agriculture, could contract, impacting up to 60% of rural households (NSSO 2019-20).

• Monsoon deficit reduces agricultural GDP growth from 4.5% (normal years) to 3.1% (El Niño years) (Economic Survey 2024).
• Budget allocation of ₹1.32 lakh crore for agriculture in 2023-24 includes irrigation and drought mitigation (Ministry of Agriculture).
• Drought affected 68 million hectares in 2019-20, linked to monsoon variability (NDMA Annual Report).

Institutional Framework for Monsoon Forecasting and Disaster Management

The India Meteorological Department (IMD) is the primary agency for monsoon forecasting, operating under the Ministry of Earth Sciences (MoES). The National Disaster Management Authority (NDMA) coordinates preparedness and response for climate-induced disasters under the Disaster Management Act, 2005 (Sections 6 and 10). The Environment Protection Act, 1986 (Section 3) empowers the central government to take measures against environmental threats including climate variability. NITI Aayog provides policy advice on water and agricultural sustainability, while NABARD finances irrigation and climate resilience projects. The Central Water Commission (CWC) monitors water resources and flood management.

• Article 253 of the Constitution enables Parliament to legislate for international climate agreements.
• IMD’s monsoon forecast categories: normal (96-104% LPA), below-normal (90-96% LPA), deficient (<90% LPA).
• NDMA mandates disaster preparedness and mitigation plans for drought and flood-prone areas.

Comparative Insights: Australia’s El Niño Adaptation Model

Australia’s Bureau of Meteorology integrates advanced El Niño forecasting with adaptive water management policies. This approach has reduced drought-related agricultural losses by 30% during El Niño years (Australian Government, 2022). Key features include localized agro-meteorological advisories, water allocation adjustments, and farmer-centric early warning systems. India’s monsoon forecasting, while robust at the macro level, lacks such integration and actionable advisories for smallholder farmers, limiting adaptive capacity.

Critical Gaps in India’s Monsoon Resilience

India’s monsoon forecasting does not sufficiently integrate with agro-meteorological advisories tailored to local cropping patterns and farmer needs. Early warnings often fail to trigger timely policy action or financial support for smallholder farmers. Water management remains fragmented, with only half of net sown area irrigated, increasing vulnerability to rainfall variability. Disaster preparedness mechanisms under NDMA require stronger implementation and coordination at state and district levels to mitigate drought impacts effectively.

• Need for localized agro-meteorological advisories linked to cropping calendars.
• Enhance early warning dissemination and actionable guidance for farmers.
• Expand irrigation infrastructure and promote water-use efficiency.
• Strengthen NDMA coordination with state disaster management authorities.

Way Forward: Strengthening Climate Resilience

• Integrate IMD monsoon forecasts with localized agro-meteorological advisories and extension services.
• Scale up irrigation coverage beyond 49% through targeted investments and micro-irrigation techniques.
• Implement drought contingency plans at district level with active NDMA and state disaster management authority collaboration.
• Leverage NITI Aayog’s policy frameworks to promote sustainable water and agricultural practices.
• Enhance financial instruments via NABARD to support climate-resilient agriculture and water infrastructure.
