The El Nino Effect on India’s Agriculture
El Nino is the natural phenomenon of climate change which initially warms the oceanic water on the surface in the Central and eastern Equatorial Pacific region. It is basically the warm phase of the El Nino Southern Oscillation (ENSO). Today’s blog discusses the major changes, types, major crops affected, and how they impact agriculture globally.

What is El Nino Effect?
The term “El Nino” stands for “The Little Boy” in Spanish. This term was introduced by a Peruvian fisherman who observed the warmer ocean waters during December. It is a climatic phenomenon characterized by the periodic warming of the central and eastern equatorial Pacific Ocean which causes the weather impact in many parts of the world.
How does El Nino Affects India’s Agriculture?
In India, more than half of the population are involved in agriculture for their livelihoods and thus are highly dependent on the monsoon. Due to El Nino, major concerns have been raised in the farming community. From late rainfall to rising temperatures, the effect of El Nino is impacting on the climatic conditions, which are felt in crop production, harvesting activities, and farmer’s income.
According to the World Meteorological Organisation's forecast, there is a strong indication of 80% likelihood of an El Nino event during June to August 2026. It has been estimated that it will continue until November with 80% or above.
What are the Different Types of El Nino Effect?
There are two major types of El Nino Effects which are Eastern Pacific and Central Pacific. Let’s discuss both in detail:
Eastern Pacific El Nino
The eastern El Nino is the traditional type of climatic effect where the temperature of the sea rises significantly in the eastern tropical pacific in Peru, Ecuador, and parts of Chile.
Central Pacific El Nino
It features warming centered in the central equatorial Pacific. It often brings different weather patterns, such as altered rainfall over India and increased hurricane activity in certain parts of the Atlantic.
What is the Difference between El Nino and La Nina?
The major difference between El Nino and La Nina are described below:
|
El Nino |
La Nina |
|
El Nino brings warm water to the central and eastern Pacific. |
La Nina brings cold water to the eastern Pacific. |
|
El Nino lasts from nine to twelve months. |
La Nina lasts from one to three years. |
|
In Southeast Asia and India, El Nino makes the weather dry. In the southern US and parts of South America, it makes the weather wet. |
La Nina brings more rain to Southeast Asia and India, but it gets cold and wet in Canada and the northern US in winter.
|
|
El Nino makes hurricanes more common in the Pacific but less common in the Atlantic. |
On the other hand, La Nina increases the frequency of Atlantic hurricanes. |
Major Crops Affected by El Nino
Many crops in India are being affected by El Nino. But some of the majorly affected crops are:
|
Crops Affected |
Reasons |
|
Due to irregularity of rainfall and pest outbreaks. |
|
|
Requires standing water; highly sensitive to rainfall deficit. |
|
|
Highly sensitive to moisture stress. |
|
|
Need water availability for a longer duration. |
What are the Safety Measures to Mitigate the Impact of El Nino?
Climate cannot be changed by farmers, but they can adapt some practices to combat El Nino effect. Some of the practices are listed below:
- Check on the weather forecast and adjust sowing time according to rainfall patterns.
- Select climate resilient crops which need less water and are drought tolerant.
- For improved water management, use drip irrigation and practice rainwater harvesting.
- Improve the soil health by adding organic matter for better water holding capacity.
- Always use crop protection solutions like agrochemical products through certified dealers.
Final Thoughts
As El Nino affects many parts of the world with its extremely warm weather conditions. In India, farmers face decreased rainfall, which go extreme to droughts and significantly impacts agriculture, water supply, and ecosystems. Therefore, we need stronger climatic adaptations, better climate resilient crops, proper sowing time and better water management. We don’t need to panic but need to adapt to these changes in agriculture through which we will combat the effects of El Nino.
