Climate-resilient agriculture means designing farming systems that can withstand climate shocks like drought, heat, floods, and erratic rainfall, recover from them, and continue to produce food and income over time.
Climate Smart Agriculture is an approach that tries to achieve three linked goals together: sustainable productivity, better adaptation and resilience to climate change, and lower greenhouse-gas emissions where possible.
Adaptation means adjusting farming to climate impacts, such as using stress-tolerant varieties or better water management, while mitigation means reducing agricultureβs contribution to climate change through actions like lowering methane and nitrous oxide emissions or increasing carbon sequestration.
Climate change affects Indian agriculture through heat stress, rainfall uncertainty, droughts, floods, changing pest and disease patterns, altered crop duration, and more risk for yield stability, especially in climate-sensitive and rainfed regions.
Stress-tolerant varieties are important because they help crops perform better under drought, heat, submergence, salinity, or other climate-related stresses, which reduces production risk and improves resilience.
Practices like crop diversification, mixed and intercropping, soil organic-matter improvement, rainwater harvesting, efficient irrigation, conservation-oriented agronomy, and contingency planning all help farms absorb climate shocks better.
Carbon sequestration matters because soils, trees, and biomass can store carbon, which links farm management with mitigation by helping remove or retain carbon while often improving soil health and resilience.
NICRA, the National Innovations in Climate Resilient Agriculture programme led by ICAR, is important because it focuses on climate-risk assessment, adaptation and mitigation research, on-farm technology demonstration, and resilience-building for vulnerable agricultural regions.
