| Syllabus: GS-III, Subject: Economy, Topic: Agriculture, Issue: Impact of climate change on crop yield |
Effect of climate change on wheat yield:
- Heat stress and temperature fluctuations.
- Early summer onset and delayed winter impact wheat growth stages.
- Warm temperatures during sowing reduce tiller formation and cause premature flowering.
The way ahead:
- India needs to invest in breeding crops resilient to climate change.
- Green Revolution 2.0 should prioritize input efficiency and climate resilience.
- Focus on producing more with less water, nutrients, and energy.
- Breeding drought-resistant and heat-tolerant varieties is crucial.
- Screening germplasm and identifying desirable genes are essential steps.
- This strategy aims to ensure food security amidst changing climate conditions.
