Why in News?

Environmental think tank Council on Energy, Environment and Water has carried a first-of-its-kind district-level climate vulnerability assessment, or Climate Vulnerability Index (CVI), in which it has analysed 640 districts in India to assess their vulnerability to extreme weather events such as cyclones, floods, heatwaves, droughts, etc.

How is the Climate Vulnerability Index assessed?

  • The CVI maps exposure (that is whether the district is prone to extreme weather events), sensitivity (the likelihood of an impact on the district by the weather event), and adaptive capacity (what the response or coping mechanism of the district is).
  • It helps map critical vulnerabilities and plan strategies to enhance resilience and adapt by climate-proofing communities, economies and infrastructure.
  • Instead of looking at climate extremes in isolation, the study looks at the combined risk of hydro-met disasters, which is floods, cyclones and droughts, and their impact.
  • The study does not take into consideration other natural disasters such as earthquakes.

What are the findings of the climate vulnerability index?

According to CVI, Assam, Andhra Pradesh, Maharashtra, Karnataka and Bihar are most vulnerable to extreme climate events such as floods, droughts and cyclones in India.

  • While 27 Indian states and union territories are vulnerable to extreme climate events, 463 districts out of 640 are vulnerable to extreme weather events
  • Dhemaji and Nagaon in Assam, Khammam in Telangana, Gajapati in Odisha, Vizianagaram in Andhra Pradesh, Sangli in Maharashtra, and Chennai in Tamil Nadu are among India’s most climate vulnerable districts
  • More than 80 per cent Indians live in districts vulnerable to climate risks – that is 17 of 20 people in India are vulnerable to climate risks, out of which every five Indians live in areas that are extremely vulnerable
  • More than 45 per cent of these districts have undergone “unsustainable landscape and infrastructure changes’’.

Facts  For Prelims:

Time for India’ drive:

  • Sweden set to launch ‘Time for India’ drive.
  • This will be a trade promotion event to boost bilateral trade.
  • Under it, there shall be no requirement for vaccination for entry nor will there be a quarantine regime in place. But travellers need to take a COVID-19 test on arrival.


  • There are now 75 AY lineages identified, each with different additional defining mutations in their genome.
  • One of these “AY.4” has been steadily growing in proportion in the UK over the last few months, accounting for 63% of new UK cases in the last 28 days.
