An active El Niño weather pattern is expected to bring below-normal rainfall and higher temperatures to several Indian states [1, 2].
This climatic shift is critical because it suppresses the Indian monsoon, which provides the primary water source for agriculture and drinking water across the region [1]. A failure in these rains can lead to widespread drought, threatening the livelihoods of millions of farmers and the stability of food supplies [2].
South Indian states are identified as the most vulnerable to these conditions [1]. Specifically, Karnataka, Andhra Pradesh, Telangana, Tamil Nadu, and Kerala face the highest risk of severe water shortages [1]. While some reports suggest the phenomenon will affect all of India, the impact is expected to be most acute in the south [1, 2].
The agricultural sector faces significant threats, particularly regarding sugarcane production [2]. Because sugarcane is a water-intensive crop, the predicted lack of rain could drastically reduce yields [2]. This creates a ripple effect in the industrial sector, as lower sugarcane output directly threatens the production of ethanol [2].
El Niño occurs due to the periodic warming of the central Pacific Ocean [1]. This warming alters atmospheric circulation, which typically results in the suppression of the monsoon rains that the subcontinent relies upon for its annual agricultural cycle [1].
Reports indicate that the current El Niño episode began in 2024 [1]. The resulting temperature spikes and rainfall deficits continue to challenge water management systems in the most affected southern regions [1, 2].
“El Niño typically suppresses the Indian monsoon, leading to reduced rainfall and higher temperatures.”
The intersection of a warming Pacific and a suppressed monsoon creates a systemic risk for India's energy and food security. By threatening sugarcane, El Niño does not only impact farmer incomes but also disrupts the government's ethanol blending targets, potentially increasing reliance on imported fuels while simultaneously straining urban water grids in the south.
