Enumerate the impact of climate change with reference to agricultural production. Present the opinion of public on climate change.
Climate change has emerged as one of the most pressing challenges to agriculture. Rising temperatures, unpredictable rainfall, and increasing frequency of extreme weather events directly affect crop productivity, soil health, and water availability.
Impacts on agricultural production:
Temperature rise: Prolonged heat stress accelerates crop maturity, reduces grain filling, and lowers yields in wheat, rice, and pulses.
Rainfall variability: Erratic monsoons lead to crop failures in rainfed regions, increasing dependence on irrigation.
Water stress: Glacial retreat and groundwater depletion aggravate irrigation scarcity, particularly in Indo-Gangetic plains.
Pests and diseases: Warmer climates expand the range of pathogens and insect pests, increasing crop losses.
Livestock productivity: Heat stress reduces milk yield and animal fertility.
Soil degradation: Intense rainfall accelerates erosion, while high temperatures reduce organic matter.
Public opinion on climate change:
Farmers perceive climate change through declining yields, delayed sowing, and frequent droughts or floods. Rural communities often view it as a direct threat to livelihoods and food security. Urban populations, on the other hand, link it with rising food prices, scarcity of water, and health issues. Younger generations and environmental groups advocate for climate-smart agriculture, renewable energy, and policy reforms. At the same time, misinformation and limited awareness among marginal farmers often hinder adaptation efforts.
Conclusion: Climate change is not just an environmental challenge but a socio-economic one. The public increasingly demands sustainable practices, government support, and scientific innovations to secure agricultural production.
