Pointer from wheat

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.
