West Bengal
From the Sundarbans delta to the Darjeeling hills, the state's geography ranges from mangrove ecosystems and a cyclone-exposed coast to flood-prone river plains and Himalayan slopes. Net warming trend established between 1969–2005; arsenic and fluoride contamination in drinking water, and 64% of rural households in kutcha/semi-pucca dwellings make the WBAPCC's integrated approach across Sundarbans protection, agriculture, livestock and habitats critical.

About West Bengal SAPCC
SAPCC Overview
West Bengal's WBAPCC was prepared under the Department of Environment, Government of West Bengal — its 1st part submitted to MoEF in April 2011, with the 2nd version adding chapters on Habitats, Sundarbans and Darjeeling Himalayas (PDF p.13). The plan covers about 10 climate-sensitive sectors organised around NAPCC missions, with about 70% of the rural population livelihood-dependent on natural resources — addressing Sundarbans delta SLR (5.7 mm/yr along the WB coast, possible 7.46 m sea surge), Darjeeling hills, Gangetic plains and a cyclone-exposed Bay of Bengal coast.
Climate profile
- Net warming trend in annual AVERAGE temperature during 1969-2005; minimum temperatures rose +0.25 to +1.5°C, while maximum temperatures declined slightly (-0.25 to -0.5°C) (PDF p.11).
- Trends of annual rainfall analysed across different agro-climatic zones; 2021-2050 projections indicate +1.8 to +2.4°C warming with shifting rainfall and intensifying extreme-rain events.
- Sundarbans, Darjeeling hills, Gangetic plains and coastal zones each face distinct climate vulnerability profiles; sea-level rise of 5.7 mm/yr observed along the West Bengal coast — among the highest along the Indian coastline.
Climate stress at a glance
- Sundarbans face SLR-driven inundation; mangroves and Royal Bengal Tiger habitat under climate stress; potential 7.46 m sea surge under extreme cyclone scenarios (PDF p.11).
- Arsenic contamination in 81 blocks and excess fluoride in 49 blocks of drinking water; water-borne diseases such as diarrhoea and enteric fever remain high, with about 20-2.7 Million diarrhoea cases reported annually 2008-2010 (PDF p.119).
- 64% of rural households live in kutcha or semi-pucca houses — high climate-livelihood vulnerability; 0.147 MT CH₄ annual urban-waste emissions (PDF p.25-26).
