The Sea Level Of Bangladesh

Decent Essays

The effects of sea level rise are profound throughout the western coastal zone as it is low-lying and the coastal lands are subsiding (Karim and Mimura 2008) . Coastal wetlands such as salt marshes and mangroves will decrease in number unless they have a sufficient sediment supply to keep pace with Sea Level Rise. These physical impacts, in turn, have both direct and indirect socioeconomic implications, which appear to be immensely negative (Cazenave and Nicholls 2010).For example, based on national studies, a 1 m rise could cause losses of about 9.5 million tons of rice in Bangladesh (Mimura and Nicholls 2008). Rice is the staple crop of half of world’s population and it is the most major staple sustenance for Bangladesh. Sea level Rise will result in a food crisis in some regions of Bangladesh especially southern sub-regions as these areas are most vulnerable to flooding due to sea level rise; hence, rice production will be unsuitable (Karim 2014).

A preliminary analysis of the sea level of Bangladesh was done to examine the one-metre rise in sea level (Huq et al.1995). Huq and colleagues (1995) conducted a study that included data on topological maps, tidal tales, satellite images, aerial photos, and hydrographic maps. Thematic maps were used to estimate the effect of a one-meter sea-level rise on agriculture, population, and infrastructure. Locations experiencing subsidence included the Chalan Beel, Dhaka Depression, and the Khulna Sundarbans area with
