As El Niño conditions rapidly develop in the Pacific, Asia’s rice-dependent economies brace for drier monsoons and potential supply disruptions in the second half of 2026.

A potent El Niño event is forecast to emerge in the coming weeks and persist through the Northern Hemisphere winter of 2026-27, raising serious concerns for agricultural production across South and Southeast Asia. Meteorologists from NOAA and other agencies indicate an 82 per cent chance of El Niño developing by June-July 2026, rising to 96 per cent through winter.

This shift from near-neutral conditions to warmer equatorial Pacific sea surface temperatures could weaken monsoons and bring drier conditions to major rice-producing regions, threatening food security for billions.

The Science Behind the Shift

El Niño, part of the El Niño-Southern Oscillation (ENSO), occurs when trade winds weaken, allowing warm water to shift eastward across the Pacific. This alters global atmospheric circulation, often leading to suppressed rainfall in the western Pacific and increased precipitation in the eastern Pacific.

Current forecasts suggest sea surface temperatures are rising sharply, with models projecting strong anomalies potentially qualifying as a “super” El Niño, though experts caution that impacts vary and are not guaranteed to be extreme.

The transition is expected to become evident from July 2026, with peak effects on tropical agriculture from August to October, and possibly extending into early 2027.

Impact on Asia’s Rice Heartland

Asia accounts for over 90 per cent of global rice production, with key players including India, Indonesia, Vietnam, Thailand, the Philippines, and Malaysia. These regions are highly vulnerable to El Niño-induced dryness because much rice cultivation remains rainfed.

• India: The southwest monsoon, critical for kharif rice planting, may be weaker than normal. Reduced rainfall could stress rainfed areas and strain irrigation systems, affecting overall output. India’s rice production supports both domestic needs and substantial exports.
• Southeast Asia (Indonesia, Malaysia, Philippines, Thailand, Vietnam): Forecasters predict below-normal rainfall, particularly from September to February. This threatens main and secondary rice seasons. Historical data shows El Niño events can reduce rice yields by 4-12 per cent in the region due to water stress during critical growth stages.

In the Philippines, where only about 40 per cent of rice land is irrigated, El Niño could slash output by several million metric tons. Palm oil production in Indonesia and Malaysia may also suffer, tightening global vegetable oil supplies.

Southern China faces the opposite risk: excessive rainfall and flooding, which could damage rice and vegetable crops.

Broader Agricultural and Economic Ripples

Beyond rice, El Niño is expected to affect other tropical commodities:

• Sugar, Coffee, and Cocoa: Drier conditions in parts of Southeast Asia and West Africa could reduce yields.
• Global Markets: Lower Asian rice supplies may push international prices higher, compounding pressures from other factors like fertilizer costs linked to geopolitical tensions.
• Africa and South America: Mixed impacts include drier conditions in southern Africa and parts of Brazil, versus wetter weather in southern Brazil and northwestern South America.

Farmers in vulnerable areas may face higher irrigation costs, reduced incomes, and debt risks. Food-importing nations like the Philippines could see increased reliance on imports, straining budgets and raising consumer prices.

Historical Lessons and Current Context

Past strong El Niño events, such as 2015-16 and 2023-24, demonstrated significant disruptions. In 2023-24, drought hit rainfed rice areas hard, contributing to yield drops and export restrictions that rippled through global markets.

The 2026 event arrives amid recovering stocks but persistent challenges, including high input costs and climate variability. While some models hint at record strength, experts emphasize that every El Niño is unique and outcomes depend on multiple factors.

Mitigation and Adaptation Strategies

Governments and international organizations are monitoring developments closely:

• Early Warning and Preparedness: Enhancing irrigation infrastructure, promoting drought-resistant rice varieties, and optimizing planting schedules.
• Policy Responses: Strategic rice stockpiling, targeted subsidies for farmers, and careful management of exports to balance domestic and global needs.
• Longer-Term Resilience: Investing in climate-smart agriculture, better water management, and diversified cropping systems can reduce future vulnerability.

FAO and regional bodies have previously highlighted the need for integrated approaches combining weather forecasting with agronomic support.

Outlook and Uncertainties

While the probability of El Niño is very high, the exact intensity and regional rainfall deviations remain uncertain. Summer atmospheric patterns could influence development. Northern Hemisphere impacts (e.g., on North America) are expected to be more pronounced later in the cycle.

For Asia’s rice bowl, the coming months will be critical. Farmers, traders, and policymakers must prepare for a potentially volatile period that could test food security across the region.
