Rehabilitation and improvement for climate resilient coastal polders inclusive of local community & ecosystem in the southwest region and Sundarbans area
Program Duration: Medium to Long Term
Tentetive Total Cost (Billion BDT): 1014
Bangladesh coast is vulnerable to tropical cyclonic storms and tidal surges, flood and waterlogging, sea-level rise, salinity intrusion, drought, riverbank, and coastal erosion, groundwater declination, environmental degradation, water quality issues, and ecosystem habitat loss due to its geographic location, flat and low-lying topography, seasonal variability, high population density, high level of poverty and extreme climatic conditions. According to the BBS Yearbook (2014), 21 cyclones and severe cyclonic storms hit the Bangladesh coast from 1960-to 2010 and caused severe losses and damages in each event. The encircled earthen polders and cyclone shelters function as the most prioritized disaster risk mitigation measures during the disaster period, which protect life, livelihoods, and tons of staple crops.
However, due to the potential impacts of climate change, the Coastal Zone of Bangladesh is identified as more exposed to coastal inundation and salinity due 0.3 m to 1 m sea-level rise by 2100 coupled with a severe cyclonic surge which will likely to lead significant damages of infrastructures, croplands and trigger shortages of drinking water in the coastal urban area, scarcity of water for irrigation for dry season agriculture and substantial changes in the coastal aquatic ecosystems. Therefore, rehabilitation, repair, or new construction of such polders and multipurpose cyclone shelters should be prioritized to ensure the first line of defense for the coastal communities.
Previously, 10 polders were rehabilitated under Coastal Embankment Improvement Project, Phase 1, and 22 more polders were improved under Phase 2. Besides, rehabilitation works of 13 polders are ongoing under the sponsorship of GoB. Still, around 2156.3 km embankment (52 polders) are identified as highly vulnerable through storm surge modeling of CEGIS due to the combined effect of 15-20 cm sea-level rise and storm surges which need to be rehabilitated within 2050 to protect the areas. A total 1485.6 km embankment (26 polders) is prioritized as moderately vulnerable due to the combined effect of 50 cm sea level rise and storm surges needed to rehabilitate within 2100. Modeling also reveals new unprotected areas in Gopalganj, Jhalokati, Pirojpur, Barisal, and Lakshmipur to get inundated due to 50 cm sea-level rise in 2100.
There are around 2,500 cyclone shelters and multipurpose cyclone shelters along the coastal belt of Bangladesh. Emphasis should be given to establishing additional cyclone shelters owing to population growth and increasing climate-induced disasters and calamities.
In this regard, this project will be undertaken to repair, construct and rehabilitate coastal polders, sea dyke, embankments, and cyclone shelters considering the sea level rise and extreme storm surge height under climate change scenarios to give protection of natural disasters to the coastal communities.
