Sea-Level Rise and Species Conservation in Bangladesh’s Sundarbans Region

This paper develops a methodology for identifying high-priority species conservation areas in Bangladesh’s Sundarbans region, an UNESCO World Heritage site, considering both species vulnerability and the likelihood of inundation by future sea-level rise (SLR). Our species vulnerability analysis develops a composite spatial vulnerability indicator based on total species counts, endangered species counts, endemicity, and four.. Read More

The impact of climate change and aquatic salinization on mangrove species in the Bangladesh Sundarbans

This paper investigates the possible impacts of climate change on aquatic salinity and mangrove species in the Bangladesh Sundarbans. The impact analysis combines the salinity tolerance ranges of predominant mangrove species with aquatic salinity measures in 27 scenarios of climate change by 2050. The estimates indicate significant overall losses for Heritiera fomes; substantial gains for.. Read More

Mangroves as Protection from Storm Surges in Bangladesh

This paper evaluates the protective capacity of mangrove forests against storm surge in seven coastal locations of Bangladesh, where surge heights can range from 1.5 to 9 meters. Estimates confirm varying levels of protection from different species, width, and density of mangrove forests. The findings highlight that mangroves must be used along with built infrastructure..

Impact of Climate Change and Aquatic Salinization on Mangrove Species and Poor Communities in the Bangladesh Sundarbans

This paper investigates possible impacts of climate change on the poor communities of the Bangladesh Sundarbans via changes in aquatic salinity and mangrove species. The impli-cations for poor communities are assessed by computing changes in high-value mangrove species for the five sub-dis-tricts in the Sundarbans. The results of the impact analysis indicate highly varied patterns.. Read More

Climate proofing infrastructure in Bangladesh : the incremental cost of limiting future inland monsoon flood damage

Two-thirds of Bangladesh is less than 5 meters above sea level, making it one of the most flood prone countries in the world. Severe flooding during a monsoon causes significant damage to crops and property, with severe adverse impacts on rural livelihoods. Future climate change seems likely to increase the destructive power of monsoon floods… Read More


Vulnerability of Bangladesh to cyclones in a changing climate : potential damages and adaptation cost

This paper integrates information on climate change, hydrodynamic models, and geographic overlays to assess the vulnerability of coastal areas in Bangladesh to larger storm surges and sea-level rise by 2050. The approach identifies polders (diked areas), coastal populations, settlements, infrastructure, and economic activity at risk of inundation, and estimates the cost of damage versus the.. Read More

Climate change and soil salinity: The case of coastal Bangladesh

This paper estimates location-specific soil salinity in coastal Bangladesh for 2050. The analysis was conducted in two stages: First, changes in soil salinity for the period 2001–2009 were assessed using information recorded at 41 soil monitoring stations by the Soil Research Development Institute. Using these data, a spatial econometric model was estimated linking soil salinity.. Read More
