Climate risk: 9 Indian states among top vulnerable places in the world

In News
  • The vast majority (80%) of 50 provinces facing the highest climate risk to their physical infrastructure by 2050 are in China, the US, and India, according to a ranking released recently by Cross Dependency Initiative.
Major Highlights
  • In India, Punjab, Bihar, Uttar Pradesh, Maharashtra, Rajasthan, Tamil Nadu, Gujarat, Kerala and Assam are the most vulnerable, the ranking indicates underlining that India’s commercial capital, Mumbai is at high risk.
  • India has nine states in the 50 high risk states; China, 26, and the US, five.
  • Two of China’s largest sub-national economies – Jiangsu and Shandong – top the global ranking; followed by the U.S. which has 18 regions in the top 100 list.
  • Asia dominates the list with 114 of the top 200 regions falling in the continent, including Pakistan, Indonesia and most South East Asian countries.
  • Devastating flooding in 2022 affected 30% of the area of Pakistan and has partially or fully damaged more than 9 lac houses in Sindh province.
  • 9 Indian states that are ranked within the top 50 most at-risk states and provinces will witness an average of 110 per cent increase in damage risk by 2050.
  • Currently, with a 0.8 degrees rise in temperature, India’s 27 states and more than three-quarters of its districts are extreme event hotspots accounting for a 5 percent loss in GDP.
  • If global warming is not limited to 2-degree thresholds, climate-vulnerable states like Assam, Bihar, Uttar Pradesh, among others, will lose more than 10 per cent of their gross state domestic product (GSDP).
  • Bihar, Assam, and Tamil Nadu had the highest ADR among other Indian States. Assam, in particular, would witness the maximum increase of climate risk: rising up to 330% by 2050.
  • Assam has witnessed an experienced exponential increase in flood events since 2011, and it had 15 of India’s 25 districts most vulnerable to climate change.
  • 11 of the 36 districts in Maharashtra were found to be “highly vulnerable” to extreme weather events, droughts and dwindling water security.
About the report
  • The index calculated the ‘Physical climate risk’ to built environments such as buildings and properties across 2,600 States and provinces globally in 2050.
  • The index assigned an Aggregated Damage Ratio (ADR) to each region, which signifies the total amount of damage a region’s built environment would sustain in 2050. A high ADR signifies more peril.
