  • 22 Feb 2023
  • 9 min read

Prelims: Gross domestic climate risk ranking, RCP8.5,

Mains: Climate risks, Adaptation and Mitigation

Why in News?

According to Gross Domestic Climate Risk ranking by Cross Dependency Initiative (XDI), India has nine states in the 50 high risk states including Punjab, Bihar, Uttar Pradesh, Maharashtra, Rajasthan, Tamil Nadu, Gujarat, Kerala and Assam.

  • XDI is a global organisation specialising in climate risk analysis for regions, banks and companies.

What is this Report About?

  • 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.

What are the Findings?

  • Vulnerabilities:
    • Risk originates from 8 climate change Hazards: Riverine and surface flooding, coastal inundation (coastal flooding), extreme heat, forest fire, soil movement (drought-related), extreme wind and freeze thaw.
    • Most damage posed to built infrastructure globally is caused by “riverine and surface flooding or flooding combined with coastal inundation.
  • Global Findings:
    • According to report 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.
    • 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.
  • India Specific Findings:
    • Under high emissions scenarios such as the Representative Concentration Pathway (RCP) 8.5 , high risk provinces will witness an average of 110% increase in damage risk by 2050.
      • Currently, with 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% loss in GDP.
    • If global warming is not limited to 2-degree thresholds, climate-vulnerable states in India will lose more than 10% 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.

What is the Significance of the Report?

  • The ranking data can also be significant for investors, as extensive built-up areas overlap with high levels of economic activity and property wealth.
    • It can inform climate resilient investment, in conjunction with adaptation measures and infrastructure planning undertaken by state and provincial governments
  • The finance industry can directly compare global industrial hubs like Mumbai, New York and Berlin using a like-for-like methodology to check vulnerability of global supply chains.

What are the Steps Taken by India regarding Climate Change?

  • Global Leadership:
  • Reforms in Transport Sector:
  • India's Support to EVs:
    • India is among a handful of countries that support the global EV30@30 campaign, which aims for at least 30% new vehicle sales to be electric by 2030.
    • India’s advocacy of five elements for climate change “Panchamrit”, at the UNFCCC COP26 in Glasgow is a commitment to the same.
  • Role of Government Schemes:
  • Role of Industries in Low-Carbon Transition:
    • The public and private sectors in India are already playing a key role in meeting the climate challenge, helped by growing customer and investor awareness, as well as increasing regulatory and disclosure requirements.
  • Hydrogen Energy Mission:
    • Focus on generation of hydrogen from green power resources.
  • Perform, Achieve and Trade (PAT):
    • It is a market-based mechanism to further accelerate as well as incentivize energy efficiency in the large energy-intensive industries.

UPSC Civil Services Examination Previous Year Question (PYQ)

Prelims

Q1. Which of the following best describes/describe the aim of ‘Green India Mission’ of the Government of India? (2016)

  1. Incorporating environmental benefits and costs into the Union and State Budgets thereby implementing the ‘green accounting’.
  2. Launching the second green revolution to enhance agricultural output so as to ensure food security to one and all in the future.
  3. Restoring and enhancing forest cover and responding to climate change by a combination of adaptation and mitigation measures.

Select the correct answer using the code given below.

(a) 1 only
(b) 2 and 3 only
(c) 3 only
(d) 1, 2 and 3

Ans: (c)

Exp:

  • National Mission for a Green India, also known as Green India Mission (GIM), is one of the eight missions outlined under India’s National Action Plan on Climate Change. It was launched in February 2014.
  • To increase forest/tree cover to the extent of 5 million hectares (mha) and improve quality of forest/tree cover on another 5 mha of forest/non forest lands. Separate sub-targets existing for different forest types and ecosystems (eg., wetland, grassland, dense forest, etc.). Hence, statement 3 is correct.

Q2. The scientific view is that the increase in global temperature should not exceed 2°C above pre industrial level. If the global temperature increases beyond 3°C above the pre-industrial level, what can be its possible impact/impacts on the world? (2014)

  1. Terrestrial biosphere tends toward a net carbon source.
  2. Widespread coral mortality will occur.
  3. All the global wetlands will permanently disappear.
  4. Cultivation of cereals will not be possible anywhere in the world.
