“Alternative technologies for a climate-change-resilient India”

 

1. Interpretation & Key Theme

  • Central idea:
    • To adapt to and mitigate climate change, India must deploy technologies beyond conventional fossil-fuel models—spanning renewable energy, water-smart systems, climate-adaptive agriculture, green infrastructure, and circular economy solutions.
  • Underlying message:
    • Technological innovation, when tailored to India’s socio-economic context, can build resilience against extreme weather, resource scarcity, and ecological degradation.

Revision Tip:
Remember “Three‐P” framework: Preventive (renewables, efficiency), Protective (water harvesting, drought-resistant crops), Planning (smart cities, circular economy).

2. IBC-Style Outline

Introduction

  • Hook: “When Kerala’s 2018 floods submerged 1.4 million hectares of cropland and displaced 800,000 people, it underscored the urgent need for climate-resilient technologies adapted to India’s diverse ecosystems.”
  • Definitions:
    • Climate-change resilience: capacity to withstand, adapt to, and recover from climatic shocks (droughts, floods, heatwaves).
    • Alternative technologies: innovations beyond business-as-usual—renewables, efficient water management, agro-climatic interventions, green materials.
  • Thesis: “By embracing solar and wind power, decentralized water-harvesting systems, climate-smart agriculture, circular waste solutions, and green infrastructure, India can simultaneously reduce greenhouse gas emissions and bolster its defense against intensifying climate hazards.”
