El Niño, its impact on global agriculture, and how to mitigate it

The climatic phenomenon known as El Niño is becoming one of the greatest threats to global agriculture. This event, characterized by the anomalous warming of the surface waters of the Pacific Ocean, alters global weather patterns, affecting the climate and, consequently, agricultural systems in various regions of the world. Below, we explore the main effects of El Niño on agriculture and how this phenomenon is amplifying pre-existing climate challenges.

Increase in food prices
and food security

One of the most visible effects of El Niño is the rise in food prices. The scarcity of crops due to droughts and floods leads to a decrease in the supply of agricultural products, raising costs in international markets.

The example of
Southeast Asia

In Southeast Asia, rice production, which represents 60% of cereal consumption, is extremely vulnerable to the lack of rainfall. This scenario will likely result in price increases, affecting both producers and consumers. (3)

Phytosanitary and
environmental effects

The increase in temperatures and extreme weather conditions create a favorable environment for the proliferation of pests and diseases in crops. This will force farmers to use more agrochemicals, raising costs and generating a greater environmental impact.

Increase in
diseases and pests

More humid climatic conditions favor the appearance of fungal diseases, while droughts weaken plants, making them more susceptible to pests.

The use of biostimulants in agriculture is emerging as a key solution to mitigate the effects of phenomena like El Niño. These products, which promote crop resilience to abiotic stress, are gaining ground as an essential tool to face adverse climatic conditions.

What are biostimulants and how do they help mitigate the effects of El Niño?

Biostimulants are new agricultural inputs designed to improve plant tolerance to stress, such as drought or excess water, optimizing nutrient use and strengthening plants. These products not only help maintain crop vitality during stress periods but also promote consistent yields, even under adverse climatic conditions.

Reducing abiotic stress
with biostimulants

Abiotic stress, such as that caused by the droughts and floods brought by El Niño, is responsible for more than 50% of agricultural losses worldwide. Biostimulants reduce these impacts by increasing plants’ ability to withstand these conditions, improving soil health, and promoting nutrient retention.

Conclusion

El Niño is a growing threat to global agriculture, exacerbating the effects of climate change and affecting global food security. While farmers face great challenges, the implementation of adaptation strategies, such as the use of biostimulants, offers a promising way to mitigate the effects of this phenomenon and protect food systems against adverse climatic conditions. The adoption of sustainable technologies will be key to ensuring crop resilience and food security in an uncertain future.
