El Niño in a hotter world: acting early to protect food and livelihoods

El Niño is a natural climate phenomenon in which surface waters in the central and eastern Pacific Ocean become unusually warm, disrupting weather patterns around the world. It usually occurs every two to seven years and typically lasts nine to twelve months. Depending on its strength and timing, El Niño can bring serious risks for food production, rural livelihoods and food security.

Today, El Niño unfolds in a world already made hotter by climate change. Greenhouse gas emissions are raising the global temperature baseline, making extreme weather more likely and more damaging. When El Niño arrives on top of that, it can shift rainfall and temperature patterns in ways that bring deeper drought, more extreme heat and increased wildfire risk to some regions, while bringing heavier rains, flooding and marine heatwaves to others.

The first impacts are often felt where food is produced. Farmers, pastoralists, fishers and other small-scale producers bear the most direct burden when rains fail; fodder becomes scarce, floodwaters rise and oceans warm.

To minimize losses, the first step is knowing precisely where food and agriculture are most exposed. FAO uses agricultural stress and drought-risk analysis to map where El Niño-linked threats to cropland and pastureland are most severe.

FAO also works closely with national counterparts and partners on risk monitoring; early warning and anticipatory action triggers hazards – such as drought, floods and storms – which become more likely during El Nino. This information can strengthen anticipatory action, rapid response and funding appeals, helping governments, humanitarian agencies and partners move faster toward the places where support is needed most.

Anticipatory action can then help producers prevent losses before they take hold, thereby safeguarding food security and reducing humanitarian needs. Anticipatory actions implemented by FAO include the distribution of drought- and heat-tolerant seeds and breeds, animal feed, improved access to water, animal health support, pest management measures, equipment and tools to protect agricultural production and produce from the impact of floods and cyclones, and planting advice and guidance for fishing communities facing warmer waters, storms or disrupted catches. Early warning and the provision of anticipatory assistance  enable communities to enter challenging seasons with more options and greater resilience. 

But El Niño preparedness is not only about the next harvest. Its damage can carry into subsequent planting cycles, leaving farmers with degraded soils, depleted seed supplies, weakened livestock and lost assets. One failed season can make the next crisis harder to survive. 

Although El Niño and climate change have different causes, many of the responses overlap. Measures that strengthen agrifood systems against El Niño also help protect them against longer-term climate extremes driven by global warming.  

El Niño is a preview of the risks a hotter future will bring. Adequate funding for anticipatory action can help prevent climate hazards from becoming food crises. Investments in resilience and adaptation need to look beyond the immediate harvest, to the next season and the one after that. The aim is to protect food security and livelihoods before losses deepen, while building systems that can better withstand the climate extremes still to come.

In parts of Southeast Asia, El Niño typically results in below-normal rainfall, especially during the height of the monsoon season (June-September) in much of South Asia. The phenomenon may also bring drier weather in some of the Pacific islands, threatening food and water shortages. Meanwhile, in Central Asia it’s usually associated with above-average rainfall, which can trigger floods and landslides, washing away seeds and destroying crops and livestock.

El Niño has generally brought above-average rainfall between October and December in the Horn of Africa. This can cause flooding and landslides, impacting agriculture and increasing the risk of disease. Below-average rainfall is observed in the western unimodal parts of East Africa (western Ethiopia, Sudan, South Sudan, Uganda, western Kenya) between July and September. Across most of southern Africa, there has been reduced rainfall attributed to El Niño between November and March in past years, coinciding with the main cropping season. This could impact crop prospects and livestock productivity, exacerbating the situation in countries facing domestic food supply challenges and high levels of food insecurity. In West Africa and the Sahel, El Niño has historically brought below-average rainfall conditions between July and September, coinciding with the main agricultural season. This could worsen the situation in countries facing domestic food supply challenges and increasing reliance on imports amid high global food prices.

In the northern part of South America, El Niño results in below-average rainfall between June and the following March. In Central America, particularly in the Dry Corridor, El Niño is associated with dry conditions between June and December, potentially affecting the end of the primera season and the performance of the postrera season between September and December. The primera is the main season for maize and agricultural season in general in most of the countries in the region.
