Andhra Pradesh braces for severe El Niño impact, facing extreme heatwaves and monsoon deficit, testing disaster preparedness and agricultural resilience.
Andhra Pradesh experienced severe heatwaves in May, with temperatures reaching 48.3°C, and continued to face heatwave alerts in July.
The state is anticipating a below-normal monsoon, having recorded a significant rainfall deficit of 42.2% between June 1 and July 11.
Past strong El Niño events in 2015 and 2023 led to high heatwave fatalities and widespread agricultural losses in Andhra Pradesh.
The India Meteorological Department (IMD) forecasts a high likelihood of another strong El Niño event this year.
The Andhra Pradesh State Disaster Management Authority (APSDMA) was established following the 2015 heatwave crisis to enhance disaster preparedness.
Detailed Insights:
El Niño events, characterized by unusual warming of Pacific Ocean surface temperatures, historically lead to extreme weather patterns in Andhra Pradesh, including reduced rainfall.
The state's projected annual rainfall of 690 mm represents a 20% deviation from the long-period average, which is double the negative deviations observed in recent El Niño years.
In 2023, 54 mandals in Andhra Pradesh were declared drought-hit, resulting in losses for approximately 6.96 lakh farmers across 103 mandals.
The state government is focusing on disseminating weather information down to the village level to mitigate crop losses and improve preparedness.
A key challenge identified is the structural issue in defining agroclimatic zones, which can lead to a mismatch between agricultural advisories and ground realities for farmers.
Farmers are being encouraged to cultivate drought-hardy crops in rain-fed regions like Rayalaseema, although their willingness to adopt these new crops remains a concern.
While heatstroke deaths have significantly decreased since 2015, ensuring timely and effective weather advisories reach the farming community remains a critical area for improvement.
Key Concepts Involved:
El Niño: A climate pattern involving the abnormal warming of surface waters in the eastern tropical Pacific Ocean, influencing global weather.
Heatwave: A prolonged period of excessively hot weather, often accompanied by high humidity, posing health risks.
Monsoon: A seasonal reversal of wind direction, bringing heavy rainfall, crucial for India's agriculture, particularly the Southwest Monsoon.
Drought-hardy crops: Plant varieties that are resilient to prolonged dry spells and require minimal water for growth.
Agroclimatic Zones: Geographic regions delineated by similar climate, soil, and topographical conditions, guiding agricultural planning.
India Meteorological Department (IMD): India's national agency responsible for meteorological observations, weather forecasting, and warnings for various weather phenomena.
Andhra Pradesh State Disaster Management Authority (APSDMA): The apex state-level body for disaster management, established under the Disaster Management Act, 2005, to coordinate preparedness, mitigation, and response.
