(c) Explain El-Nino effect. Give causes and its impact on Indian Agriculture.
Ans:
Introduction: El Niño is a climate phenomenon characterized by the periodic warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean. It has widespread and significant effects on weather patterns and can profoundly impact various regions across the globe, including India. Understanding the causes and impacts of El Niño is crucial for assessing its effects on Indian agriculture.
Causes of El Niño:
Oceanic Warming: El Niño is primarily driven by the warming of sea surface temperatures in the central and eastern Pacific Ocean. Normally, trade winds blow from east to west across the Pacific, pushing warm surface waters toward the western Pacific. However, during El Niño events, these winds weaken or reverse, allowing warm waters to migrate eastward.
Atmospheric Coupling: The warming of ocean waters in the Pacific Ocean leads to changes in atmospheric circulation patterns. The warming reduces the temperature gradient between the eastern and western Pacific, weakening the Walker Circulation (east-west atmospheric circulation). This disruption further reinforces the oceanic warming, creating a positive feedback loop.
Impact of El Niño on Indian Agriculture:
Erratic Monsoon Patterns:
Drought and Water Scarcity:
Heat Stress and Crop Damage:
Increased Pest and Disease Pressure:
Shifts in Crop Patterns:
Examples of El Niño Impact on Indian Agriculture:
El Niño 2015-2016: India experienced a severe El Niño event during this period, leading to deficient monsoon rains and drought in many regions. Crop production was significantly affected, leading to food price inflation and economic challenges for farmers.
El Niño 2018: Another El Niño event in 2018 resulted in delayed and deficient monsoon rains, affecting crop sowing and yields in states like Maharashtra, Gujarat, and Karnataka.
Conclusion: El Niño is a complex climate phenomenon with far-reaching impacts on global weather patterns, including Indian agriculture. It often leads to droughts, reduced rainfall, heat stress, and increased pest pressure, affecting crop production and food security. Recognizing and monitoring El Niño events is crucial for farmers, policymakers, and agricultural stakeholders to implement mitigation measures and adapt to changing weather conditions during these events.
