Bolivia Declares Emergency Over El Nino
Why in News?
- Bolivia's President Rodrigo Paz declared a national emergency over the effects of El Nino, News On AIR reported on 1 November 2026.
- The declaration is meant to free up money and staff, improve coordination between agencies and seek more international aid.
- Drought has already hit 63 Bolivian communities, and the livestock sector faces serious shortages of animal feed.
- In Myanmar, the Yangon region has set up more than 600 heat relief shelters with room for over 150,000 people ahead of a forecast strong El Nino.
- The World Meteorological Organization expects the event to strengthen further and peak around November and December 2026.
Key Terminologies
- El Nino
- A climate pattern with unusually warm sea surface temperature in the central and eastern equatorial Pacific Ocean. It changes rainfall and temperature in many regions of the world.
- Sea Surface Temperature Anomaly
- The difference between the measured temperature of the ocean surface and its long-term average. The World Meteorological Organization tracks it to judge how strong an El Nino is.
- Indian Ocean Dipole
- A pattern of sea surface temperature difference between the western and eastern Indian Ocean. A positive phase is expected to develop in 2026 alongside El Nino.
- Victoria Mode
- A North Pacific ocean temperature pattern. In one phase it diverts moisture away from northern India, according to a 2026 study by the India Meteorological Department.
- National Emergency Declaration
- A legal step that lets a government release funds, deploy staff and request external help quickly during a disaster.
Key Issues
- Rising Strength: The World Meteorological Organization forecast an ensemble sea surface temperature anomaly of about 2.9 degrees Celsius for August to October 2026 and about 3.6 degrees for September to November. The intensification is expected to peak in November, its September update says.
- Drought and Feed: Bolivia's drought has reached 63 communities and caused feed shortages for livestock, News On AIR reported. Ranching and small farms lose income when pasture fails.
- Heat Exposure: Myanmar's Yangon region has opened over 600 heat shelters for more than 150,000 people ahead of the forecast peak, which shows how El Nino years raise heat risk in cities.
- Indian Rainfall: India's 2026 monsoon ended 12.6 per cent below normal, the weakest since 2015, with El Nino a key factor, The Tribune reported on 24 October 2026. Drought was declared in parts of Maharashtra, Karnataka, Telangana, Andhra Pradesh and Rajasthan.
- Compound Drivers: A positive Indian Ocean Dipole is expected to develop, with a seasonal mean of 0.6 degrees Celsius for August to October. Several ocean patterns acting together make impacts harder to forecast.
Key Implications
Positive/Pros/Merits
- Early Declaration: Bolivia's emergency lets it release funds and coordinate agencies before losses grow, which is the main purpose of such declarations.
- Reliable Forecasts: The World Meteorological Organization says forecast systems agree closely, which signals high confidence. Governments can plan relief ahead of the peak.
- Preparedness Model: Yangon's network of over 600 heat shelters shows a low-cost way to protect people during extreme heat.
- Better Science: A study by the India Meteorological Department and the Indian Institute of Tropical Meteorology used data from 1951 to 2020 to link poor-rainfall years in the Gangetic plains with the Victoria Mode. This improves seasonal outlooks.
Negative/Cons/Demerits
- Farm Losses: The study warned that shifting rainfall could affect paddy sowing and harvesting schedules in the northern plains. Late or deficient rain cuts yield and income.
- Climate Shift: The study found that the hot semi-arid zone in northwest India grew from about a quarter of the region in 1951 to 1980 to a third in 1991 to 2020. El Nino years add stress to an already drying region.
- Aid Dependence: Bolivia's request for more international aid shows that national budgets alone may not cover a prolonged drought.
- Global Heat: The World Meteorological Organization expects above-normal temperatures worldwide, so heat risk is not limited to drought regions.
Key Initiatives
- Bolivia, National Emergency: President Rodrigo Paz declared a national emergency over El Nino, to free up money and personnel and seek international aid, on 1 November 2026.
- Myanmar, Yangon Heat Shelters: The Yangon region set up over 600 heat relief shelters with capacity above 150,000 people ahead of the forecast peak.
- World Meteorological Organization, Seasonal Updates: The organisation issues Global Seasonal Climate Updates, including those for August to October and September to November 2026, that track the sea surface temperature anomaly and the Indian Ocean Dipole.
- India Meteorological Department, 2026 Study: With the Indian Institute of Tropical Meteorology it published an analysis of climate zones from 1951 to 2020, led by scientist Ananya Karmakar, to improve understanding of monsoon shifts.
The World Meteorological Organization says forecast systems agree closely on a strengthening El Nino that peaks in November and December. Bolivia has moved to national emergency measures, and Myanmar has opened heat shelters. The India Meteorological Department has linked rainfall variation in the northern plains to ocean patterns beyond El Nino.
Director's Perspective
Way Forward
- Link national disaster declarations to forecast triggers, so relief begins before the peak and not after crop failure.
- Expand heat shelters and cooling centres in Indian cities on the Yangon model.
- Use ocean indices such as El Nino, the Indian Ocean Dipole and the Victoria Mode together in seasonal forecasts for farmers.
- Promote drought-tolerant seed, crop insurance and fodder banks in districts hit by deficient rain.
- Share El Nino impact data across countries, so aid reaches affected regions faster.
El Nino is no longer a distant Pacific event but a global risk that now spans Bolivia, Myanmar and India. The forecast is confident, the peak is near, and the monsoon of 2026 has already shown the cost. Early declarations and heat shelters are the right instincts. In a Mains answer, credit the forecasting advances, then conclude that preparedness, and not prediction, will decide how many farmers and city dwellers are protected.

Frequently Asked Questions
What is El Nino?
El Nino is a climate pattern marked by unusually warm sea surface temperature in the central and eastern equatorial Pacific Ocean. It changes rainfall and temperature around the world, bringing drought to some regions and heavy rain to others, according to News On AIR reporting on 1 November 2026.
Why did Bolivia declare a national emergency?
Bolivia declared a national emergency on 1 November 2026 because El Nino has caused drought in 63 communities and animal feed shortages. President Rodrigo Paz's declaration is meant to release funds and staff, improve agency coordination and seek international aid.
How is El Nino linked to the Indian monsoon?
India's 2026 monsoon ended 12.6 per cent below normal, the weakest since 2015, with El Nino a key factor, The Tribune reported on 24 October 2026. An India Meteorological Department study also linked poor-rainfall years in the northern plains to the Victoria Mode ocean pattern.
