El Niño Likely to Reduce India's Monsoon Rainfall
• The El Niño-Southern Oscillation (ENSO) phenomenon, specifically during an El Niño year, is expected to significantly impact India's monsoon rainfall. According to experts from the Scripps Institution of Oceanography, El Niño typically leads to a reduction in monsoon rainfall between June and September, potentially causing drought conditions in the region. This pattern is attributed to the warming of the Pacific Ocean, which disrupts global weather systems, including the Indian monsoon. Additionally, El Niño years are associated with higher global temperatures, which may exacerbate heatwave activity in India, as observed during the early summer of
• The late onset of the monsoon, a direct consequence of El Niño, has historically been linked to extreme heat events in the country.
Impact & Risks
The reduction in monsoon rainfall during El Niño years poses significant risks to India's agriculture, water resources, and overall economy. Drought conditions can lead to lower crop yields, affecting food security and livelihoods, particularly in rural areas. Additionally, the combination of reduced rainfall and higher temperatures may intensify heatwaves, posing health risks to vulnerable populations. Urban areas could face water shortages, while rural regions may experience challenges in irrigation and drinking water supply. The cascading effects of these disruptions could have long-term socio-economic consequences.
