About West Bengal SAPCC
SAPCC Overview
West Bengal SAPCC 1.0 was prepared under the Department of Environment, Government of West Bengal. It addresses climate priorities across water, agriculture, forests and biodiversity, health, energy, sustainable habitats, the Darjeeling Himalayas and the Sundarbans.
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.
- The 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.
