About West Bengal SAPCC
SAPCC Overview
West Bengal SAPCC 1.0 was prepared under the Department of Environment. It reports that its first group of sectoral chapters was submitted to the then Ministry of Environment and Forests in April 2011, while the second version added the chapters on Animal Resource Development, Fisheries and Transport in 2017.
Climate profile
- West Bengal stretches from the Darjeeling Himalayas and Terai-Dooars in the north through the Gangetic plains and western plateau fringe to the coastal delta and Sundarbans. These regions have markedly different temperature, rainfall, river, cyclone and sea-level conditions.
- During 1969–2005, maximum temperatures generally decreased slightly while minimum temperatures increased across the state. Minimum-temperature increases were strongest in the hilly, Terai and old alluvial zones. Rainfall trends varied spatially, with increases reported in parts of northern West Bengal and the Sundarbans and decreases during some seasons and in parts of southern and western West Bengal.
- Under the A1B scenario used in West Bengal SAPCC 1.0, average maximum and minimum temperatures are projected to rise by approximately 2.2°C by the 2050s relative to the 1960–1990 baseline. Monsoon rainfall is projected to increase across much of the state, although decreases are projected for parts of the eastern coastal and western red-and-laterite zones.
Climate stress at a glance
- Tide-gauge observations cited for Diamond Harbour indicate sea-level rise of about 5.7 mm per year, partly associated with land subsidence. This compounds cyclone, storm-surge, salinity and erosion risks in the coastal delta and Sundarbans.
- West Bengal SAPCC 1.0 reports increasing trends in tropical and severe cyclonic storms over the Bay of Bengal during the historical period assessed.
- Darjeeling and other hill areas face different risks, including intense rainfall, landslides, changing springs and impacts on forests, agriculture, tea and mountain infrastructure.
