Science is woven into the fabric of daily life, from the vaccines and medicines that protect health, to smartphones and the internet that connect us, to refrigeration, sanitation and transport that shape routines. Nowhere is its transformative reach clearer than in agriculture, which feeds a nation of over 1.4 billion.

Science in everyday life

  • Healthcare through diagnostics, vaccines and telemedicine.
  • Communication and digital payments via mobile and internet technology.
  • Food safety, cold storage and clean drinking water.

Striking changes in agriculture

  • Green Revolution: high-yielding varieties, chemical fertilisers and irrigation turned India from food-deficit to surplus.
  • Biotechnology: Bt cotton and tissue culture raised yields and pest resistance.
  • Precision and digital farming: soil-health cards, remote sensing, drones for spraying, and weather advisories.
  • White and Blue Revolutions: science-led dairy and fisheries growth.

Guided by responsible science and sustainability, technology can further raise productivity, cut input use and lift farmer incomes.
