IMD Forecasts Heavy Rain in Northeast Until June 21 Amid El Nino, Warns of Kharif Crop Stress

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.

Hurricane Polo Turns Category 5; Strong El Niño May Cause 451,000 Additional Global Heat Deaths

Hurricane Polo has intensified into a Category 5 storm off Mexico's Pacific coast, with maximum sustained winds of 270 kmph. This is unfolding against an unusually strong El Niño that the WMO expects to persist through February 2027. El Niño is being watched closely because it can disrupt rainfall worldwide—the Climate Impact Lab projects 451,000 additional heat-related deaths globally, including about 15,800 in India.

Kharif Sowing Recovers to 894.22 lh (2.9% Gap), El Niño Threat Looms Over Rabi Crops

Despite a strengthening El Niño, July monsoon revived with 2.4% above LPA rainfall, narrowing kharif sowing gap to 2.9% below last year. However, El Niño is expected to become very strong by Oct-Dec 2026, with lagged effects threatening rabi crops and global food prices, especially vegetable oils. India's food stocks remain adequate but inflation risks persist.

E20 Ethanol Fuel Used in 4 Crore Vehicles; Flex-Fuel Engines to End ₹22 Lakh Cr Fuel Imports

E20 ethanol-blended petrol is being used in 4 crore four-wheelers and 20 million two-wheelers without harming vehicles and with improved mileage. Union Minister Nitin Gadkari announced that automobile companies will produce flex-fuel engines capable of running on 100% ethanol, potentially saving ₹22 lakh crore in fuel imports and boosting farmers' income through higher maize prices.

E20 Ethanol Blending Nears 20% in 2025: Water Footprint of 2,000-3,500 Litres per Litre Raises Sustainability Concerns

India's ambitious E20 ethanol blending programme—up from 1.5% in 2013–14 to nearly 20% in 2025—has reduced oil dependence but also hides serious environmental costs. Experts argue that without counting the huge water footprint of sugarcane ethanol, fossil-energy inputs, and vehicle compatibility issues, the policy risks replacing imported oil dependence with freshwater insecurity.

India's E20 Push: ₹2 Lakh Cr Forex Saved, But 77% Legacy Vehicles Face Damage Risks

India's ethanol blending programme has saved ₹2 lakh crore in foreign exchange and substituted 32 million tonnes of crude oil, but faces pushback over vehicle damage concerns for 77% of pre-2023 vehicles. The policy involves diversion of maize, FCI rice, and sugarcane juice for ethanol production, with potential food security risks during monsoon failure.

UK Met Office Forecasts Record El Nino >3°C; 2027 Likely Hottest Year on Record

The UK Met Office has forecast the strongest El Nino in over a century, with Pacific sea surface temperatures rising over 3°C above normal. This unprecedented event could make 2027 the hottest year globally, impacting global weather patterns including drier conditions in India and severe droughts in South America and the West Pacific.

SAT-1 Serotype of Foot and Mouth Disease Returns After 60 Years; NADCP & Brucellosis Key for Prelims

After 60 years, the SAT-1 serotype of Foot and Mouth Disease (FMD) has re-emerged in Europe and the Middle East, raising alarms for livestock health. India's National Animal Disease Control Programme (NADCP) aims to control FMD and Brucellosis through vaccination and biosecurity. This is critical for UPSC as it links animal disease, economic impact, and government schemes.
