IMD has revised its monsoon forecast to 90% of LPA, signaling potential agricultural distress and water scarcity, with El Niño conditions likely to exacerbate the situation.
Key points
IMD's revised forecast predicts monsoon rainfall at 90% of LPA (±4% error), down from April's 92% projection, with a 60% probability of 'deficient' monsoon (below 90% LPA).
Monsoon Core Zone (MCZ), covering rain-fed farmlands, is expected to receive below 94% LPA, threatening kharif crop yields and rural incomes.
[GS3-Economy] Below-normal rainfall may strain hydropower generation and drinking water supplies</b, impacting industrial output and urban water management.
El Niño conditions developing in the equatorial Pacific will likely intensify summer heat and weaken monsoon, historically linked to drought years in India.
Regional disparities exist: Northeast India may see normal rainfall (94-106% LPA), while Central/South Peninsula and Northwest India face below-normal precipitation.
[GS1-Geography] Delayed monsoon onset in Kerala (now expected post-June 11) is attributed to a Pacific typhoon diverting moisture and a Lakshadweep cyclonic circulation.
Heatwave alert for June predicts 5-6 heatwave days in UP, Haryana, Punjab, Bihar, Odisha, Chhattisgarh, Gujarat, and Andhra Pradesh, exceeding the normal 3 days.
This connects to GS2-Governance as it tests disaster preparedness under the National Disaster Management Plan and crisis coordination between IMD and state agriculture departments.
Way Forward: Implement micro-irrigation schemes under PMKSY, accelerate aquifer recharge programs, develop regional crop contingency plans, and integrate IMD's early warnings with state agriculture extension services.
Key terms
- Long Period Average (LPA)
- 87 cm benchmark for June-September monsoon rainfall, calculated from 1971-2020 data. Crucial for UPSC as it forms the basis for declaring monsoon as 'normal' (96-104% LPA), 'deficient' (110%), directly impacting agricultural policy and drought management.
- Monsoon Core Zone (MCZ)
- Geographic region encompassing India's rain-fed agricultural belt, where monsoon variability most affects crop productivity. For UPSC, understanding MCZ is vital for analyzing food security, farmer distress, and the efficacy of schemes like PMFBY.
- El Niño-Southern Oscillation (ENSO)
- Climate phenomenon involving Pacific Ocean temperature fluctuations. El Niño phases correlate with weaker Indian monsoons. UPSC relevance lies in its impact on inflation, rural economy, and climate change adaptation strategies under National Action Plan on Climate Change.
- Indian Ocean Dipole (IOD)
- Ocean-atmosphere interaction affecting monsoon patterns. Neutral IOD conditions, as currently observed, reduce compensatory rainfall mechanisms during El Niño years. Important for UPSC's disaster management and climate resilience questions.

Answer framework
Introduction
Briefly introduce IMD's revised monsoon forecast (90% of LPA) and mention its significance for agriculture and water security in India.
Impact on Agriculture
Threat to kharif crop yields in the Monsoon Core Zone (MCZ) due to below-normal rainfall.
Potential decline in rural incomes and increase in farmer distress.
Regional disparities in rainfall affecting crop patterns and productivity.
Water Security Challenges
Strain on drinking water supplies and hydropower generation.
Increased reliance on groundwater leading to aquifer depletion.
Urban water management challenges due to reduced reservoir levels.
Role of Climate Factors
El Niño conditions exacerbating monsoon variability and heatwaves.
Neutral Indian Ocean Dipole (IOD) reducing compensatory rainfall mechanisms.
Mitigation Measures
Implementation of micro-irrigation schemes under PMKSY.
Accelerating aquifer recharge programs and promoting water-efficient crops.
Developing regional crop contingency plans and integrating IMD's early warnings with state agriculture extension services.
Conclusion
Emphasize the need for a multi-pronged approach combining technological, policy, and community-based solutions to enhance resilience against monsoon variability.
