Introduction: Forecast and Context
The Indian Meteorological Department (IMD) forecasted in June 2024 that the southwest monsoon rainfall will be 89% of the Long Period Average (LPA), categorizing it as 'below normal' for the first time since 2013. This forecast covers the entire Indian landmass, which receives approximately 70% of its annual rainfall during the monsoon season (June to September). The last 'below normal' monsoon was recorded 11 years ago, marking a significant deviation from the recent trend of normal or above-normal rainfall years (IMD Historical Data).
This forecast has immediate implications for India's agriculture-dependent economy, water security, and disaster preparedness frameworks, given the monsoon's critical role in sustaining crop production, replenishing reservoirs, and supporting rural livelihoods.

Constitutional and Legal Framework Governing Monsoon Forecasting and Disaster Management
Article 246(3) of the Constitution of India places meteorological services under the Union List, enabling the central government to legislate and operate meteorological institutions. The Indian Meteorological Department (IMD), functioning under the Ministry of Earth Sciences (MoES) established by the Ministry of Earth Sciences Act, 2006, is the nodal agency for weather forecasting and climate monitoring.
The Disaster Management Act, 2005 (Sections 6 and 11) mandates proactive disaster preparedness and response mechanisms, including for droughts triggered by deficient rainfall. The Environment Protection Act, 1986 (Section 3) provides the legal framework for environmental safeguards that indirectly support climate resilience and variability management.
- IMD: Authorized to issue monsoon and drought forecasts.
- NDMA: Coordinates national-level disaster preparedness and response.
- State Disaster Management Authorities: Implement localized drought mitigation and relief measures.
Economic Impact of Below Normal Monsoon Rainfall
Agriculture accounts for approximately 18% of India’s GDP and employs over 50% of the workforce (Economic Survey 2023-24). A 10% shortfall in monsoon rainfall typically correlates with a 2-3% decline in agricultural output, exacerbating rural distress and food insecurity (IMD and Ministry of Agriculture data).
In 2024, the forecasted 11% deficit threatens to reduce food grain production from the 316.06 million tonnes recorded in 2022-23. States like Maharashtra and Karnataka, already water-stressed, report reservoir levels at 35% of capacity in June 2024, down from 55% last year (Central Water Commission 2023), intensifying irrigation shortages.
- Rural credit cycles are disrupted as agricultural loan non-performing assets rise by 5% during drought years (RBI Report 2023).
- Drought-affected areas increase by an average of 15% during below-normal monsoon years (Ministry of Agriculture data, 2010-2023).
- Government allocates ₹87,223 crore in 2023-24 budget for agriculture, including drought mitigation schemes.
Institutional Roles and Coordination Challenges
The IMD leads monsoon forecasting, employing global climate models and regional data. The MoES supports research on ocean-atmosphere interactions influencing monsoon variability. The Central Water Commission (CWC) monitors reservoir and river basin water levels, critical for irrigation planning.
The Ministry of Agriculture and Farmers Welfare implements drought relief and crop insurance schemes, while the National Disaster Management Authority (NDMA) coordinates disaster preparedness. The Reserve Bank of India (RBI) monitors agricultural credit flow and financial stability in rural sectors.
- Despite robust forecasting, IMD’s advisories often lack integration with localized agricultural advisories, limiting timely drought mitigation.
- State-level response mechanisms frequently suffer from delayed activation of relief funds and inefficient resource allocation.
Comparative Analysis: India vs Australia’s Seasonal Forecasting and Agricultural Advisory Systems
| Parameter | India | Australia |
|---|---|---|
| Forecasting Agency | Indian Meteorological Department (IMD) | Bureau of Meteorology (BoM) |
| Forecasting Models | Global and regional climate models; ENSO and IOD indices considered | Advanced integration of ENSO, IOD, and local climate data with machine learning models |
| Integration with Agriculture | Limited localized advisories; weak linkage with state-level drought policies | Proactive agricultural advisories linked with seasonal forecasts; real-time farmer alerts |
| Impact on Crop Losses | Drought-related crop losses remain high; reactive relief measures | 20% reduction in drought-related crop losses (2010-2020) due to integrated approach |
Significance and Way Forward
- Enhance IMD’s forecasting precision by incorporating localized agro-climatic data and real-time ground observations.
- Institutionalize coordination between IMD, Ministry of Agriculture, NDMA, and state governments for timely drought mitigation and resource allocation.
- Expand and digitize agricultural advisories based on monsoon forecasts to enable proactive farmer decision-making.
- Strengthen water resource management through real-time reservoir monitoring and demand-side interventions in water-stressed states.
- Integrate climate resilience into rural credit policies to mitigate financial distress during below-normal monsoon years.
- 'Below normal' rainfall indicates 90-96% of Long Period Average (LPA).
- 'Deficient' rainfall is less than 90% of LPA.
- IMD uses hydrological drought and meteorological drought interchangeably in monsoon forecasts.
Which of the above statements is/are correct?
- Article 246(3) places meteorological services under the Union List.
- The Disaster Management Act, 2005 empowers states to independently issue monsoon forecasts.
- The Ministry of Earth Sciences Act, 2006 established the IMD as an autonomous body.
Which of the above statements is/are correct?
Jharkhand & JPSC Relevance
- JPSC Paper: Paper 1 (Geography and Environment), Paper 3 (Agriculture and Disaster Management)
- Jharkhand Angle: Jharkhand’s agrarian economy depends heavily on monsoon rains; below-normal rainfall exacerbates water scarcity and affects paddy and maize production.
- Mains Pointer: Discuss state-specific water resource management, integration of IMD advisories with local farming practices, and disaster relief mechanisms in Jharkhand.
What defines 'below normal' monsoon rainfall according to IMD?
'Below normal' monsoon rainfall is defined as 90-96% of the Long Period Average (LPA) rainfall, as per the Indian Meteorological Department’s classification.
Which constitutional provision governs meteorological services in India?
Article 246(3) of the Constitution places meteorological services under the Union List, empowering the central government to legislate and operate meteorological institutions.
How does below normal monsoon rainfall affect agricultural output?
A 10% deficit in monsoon rainfall typically leads to a 2-3% reduction in agricultural output due to irrigation shortages and crop stress, impacting food grain production and rural incomes.
What role does the Disaster Management Act, 2005 play in drought preparedness?
Sections 6 and 11 of the Disaster Management Act, 2005 mandate the establishment of disaster management authorities at national and state levels, responsible for preparedness, mitigation, and response to climate-related disasters including droughts.
How does Australia’s Bureau of Meteorology differ from India’s IMD in monsoon forecasting?
Australia’s Bureau of Meteorology integrates advanced seasonal forecasting models with ENSO and IOD indices and links forecasts directly to agricultural advisories, reducing drought-related crop losses by 20% over 2010-2020, a practice India has yet to fully adopt.
