Impact on Agriculture — Ecological Framework
Ecological Framework
Climate change profoundly impacts Indian agriculture, a sector vital for the nation's economy and food security. Key impacts include altered monsoon patterns leading to droughts and floods, rising temperatures causing heat stress in crops like wheat and rice, and increased frequency of extreme weather events damaging harvests.
These changes result in reduced crop yields, increased pest and disease outbreaks, and accelerated soil degradation. India's diverse agro-climatic zones experience varied effects, from salinization in coastal areas to chilling hour deficits in horticulture in the Himalayas.
Policy responses, such as the National Action Plan on Climate Change (NAPCC) and its National Mission for Sustainable Agriculture (NMSA), along with schemes like Pradhan Mantri Fasal Bima Yojana (PMFBY), aim to build climate resilience.
Adaptation strategies focus on climate-smart agriculture, developing resilient crop varieties, efficient water management, and improved soil health. The challenge is multi-faceted, requiring integrated approaches to safeguard farmer livelihoods and ensure national food security in a changing climate, aligning with Sustainable Development Goals 2 and 13.
Important Differences
vs Climate Change Impacts: Traditional vs. Climate-Smart Agriculture Practices
| Aspect | This Topic | Climate Change Impacts: Traditional vs. Climate-Smart Agriculture Practices |
|---|---|---|
| Core Philosophy | Traditional Agriculture (Vulnerable) | Climate-Smart Agriculture (Resilient) |
| Water Usage | Often inefficient, high reliance on rainfall/flood irrigation, vulnerable to water scarcity. | Optimized, precision irrigation (drip/sprinkler), rainwater harvesting, efficient water management. |
| Yield Stability | Highly volatile, susceptible to extreme weather events (droughts, floods, heatwaves). | More stable, enhanced resilience to climate shocks, aims for sustainable productivity. |
| Crop Selection | Focus on high-yielding varieties, often water-intensive, limited genetic diversity. | Drought/heat-tolerant varieties, crop diversification, traditional climate-resilient crops (millets). |
| Soil Management | Intensive tillage, chemical fertilizer dependency, soil degradation, erosion. | Conservation tillage, organic farming, agroforestry, soil health management, carbon sequestration. |
| Pest & Disease Management | Reactive, heavy reliance on chemical pesticides. | Proactive, Integrated Pest Management (IPM), biological controls, resistant varieties. |
| Information & Technology | Limited access to weather forecasts, traditional knowledge-based decisions. | Utilizes weather advisories, remote sensing, IoT, precision farming tools, digital extension services. |
| Greenhouse Gas Emissions | Potentially high (e.g., methane from paddy, N2O from fertilizers). | Aims to reduce emissions, enhance carbon sinks (e.g., through agroforestry, soil carbon sequestration). |
