What This Article Covers

1.IMD's first long-range forecast predicts 2026 monsoon rainfall at 92% of LPA (with a ±5% error margin), classifying it as 'below normal'.

2.A developing El Nino, expected to peak in July, is cited as the primary dampening factor, with its strongest negative impact likely in the second half (August-September).

3.Other global phenomena like a positive Indian Ocean Dipole (IOD) and lower-than-normal Eurasian snow cover may partially offset El Nino's effect, but ENSO remains the dominant influence.

The Big Picture

Monsoon Revival: Rainfall Deficiency Drops to 11.5%, Kharif Sowing Gap Narrows to 2.9%

The monsoon has revived significantly, reducing cumulative rainfall deficiency from 22.8% to 11.5% and narrowing the kharif sowing gap from 20.8% to 2.9%. However, El Niño is strengthening into a 'very strong' event, posing a serious threat to the upcoming rabi season. Proactive supply-side management will be crucial for food security.

PM-KUSUM 2.0: Grid-Connected Solar Models Can Curb Groundwater Over-Exploitation

India’s PM-KUSUM scheme has installed 2.5 million solar pumps, raising concerns over groundwater depletion. However, the real issue is not solar irrigation itself but the model deployed. Grid-connected systems with feed-in tariffs and fee-for-service models can incentivize water conservation, while standalone pumps are better for rainfed eastern India. PM-KUSUM 2.0 must adopt a differentiated regional approach.
