The coastal zone of Bangladesh extends over 47,150 square kilometers and includes 147 sub-districts across 19 districts, accounting for 32% of the country's total area and home to 26% of its population. The coastal zone is divided into four main morphological zones: 1) the Ganges Tidal Floodplain west, 2) the Ganges Tidal Floodplain east, 3) the Meghna Deltaic Zone, and 4) the Eastern Hill Region. The coastal zone faces numerous vulnerabilities like sea level rise, coastal erosion, cyclones, pollution, salinity intrusion, flooding, and diseases. Integrated coastal zone management and other measures are needed to address these challenges.

Coastal Geography of
Bangladesh

2. Coastal zone of Bangladesh
Coastal Area : 47,150 sq. km, includes 147 Upazillas under 19 districts
It lies between latitude and longitude 89◦-93◦ E and 21◦ -23◦ N
So The coastal land zone extends over 32% of the country
population of 38.5 million=26% population of entire country=an average population
density of 817 persons per sq. km.
The landward boundary of the Bangladesh coastal zone is defined by three hydrological indicators: tidal
influence, salinity intrusion and the influence of cyclones and storm surges.
1:South West (Ganges Tidal Floodplain – West)
2: South Central (Ganges Tidal Floodplain – East)
3: South East (Young Meghna Estuarine Floodplain)
4: East and Hill (Chittagong Coastal Plains )
