Page 1 – Climate Change and Sustainable Development
Question
“Climate change has become both an environmental and developmental challenge for India.” Discuss.
Introduction
Climate change refers to long-term changes in global temperature, rainfall patterns and environmental conditions mainly caused by human activities such as industrialization, deforestation and excessive carbon emissions.
India is highly vulnerable to climate change because of its large population, agriculture dependence, long coastline and rapidly growing urbanization. Climate change today is not only an environmental issue but also a major developmental challenge.
Climate Change as an Environmental Challenge
1. Rising Temperatures
India has been experiencing increasing heatwaves and extreme temperatures in several states. Rising temperatures affect human health, water availability and biodiversity.
2. Frequent Floods and Cyclones
Heavy rainfall, floods and cyclones are increasing due to changing climate conditions. Coastal regions are becoming more vulnerable to natural disasters.
3. Water Scarcity
Irregular rainfall and declining groundwater levels are creating water stress in many parts of India.
4. Biodiversity Loss
Climate change affects forests, wildlife and ecosystems, leading to biodiversity imbalance.
Climate Change as a Developmental Challenge
1. Impact on Agriculture
Agriculture depends heavily on monsoon rainfall. Climate variability affects crop production, food security and farmers’ income.
2. Economic Losses
Natural disasters and environmental degradation increase economic burden on governments and citizens.
3. Health Challenges
Heatwaves, pollution and vector-borne diseases create public health risks.
4. Urban Challenges
Rapid urbanization combined with climate stress increases pressure on infrastructure, drainage systems and public services.
