(iii) Study seeks the adequate coastal wetlands ecosystem management strategies
and
(iv) Makes recommendations for future development policies for the coastal natural resources, protection and management of coastal deltaic degraded ecosystem in the Bangladesh coastal region.
6.3 Data and Methodology
The present study was carried out based on primary and secondary data sources.
The primary data collected from field investigation in 2003 and 2008. PRA practices were arranged with the local people at Munchiganj near Sundarbans, Koira
Upazila, and Mongla port area. The information was collected from Galachipa and
Kalapara upazilas of Patuakhali district. Besides these a various reports and published articles in journals and conference proceedings have been used for this study.
Published materials, reports and journals were collected from different government
and non-governmental organizations in Bangladesh. For secondary data collection,
CARDMA reports on coastal resource development and management was used very
openly. The especial research reports of CARDMA, FAP 24 report, BWDB, CEGIS
reports and BCAS reports were also used for this study. Beside these some interviews were arranged with water engineers, environmentalist, geographers, geologists and sociologists and expert peoples on river systems and its ecology. Besides,
the secondary data were collected from the relevant published research works in the
country and outside of the country. The published papers in journals and books in
Bangladesh and outside of country were received. The collected data were processed, analyzed, and visualized through MS Excel interpolation, VISIO 32, ArcGIS
9.3 and 10.1 software. They were used for water salinity approximation to investigate the degraded deltaic coastal floodplain wetland ecosystems in the GangesBrahmaputra Rivers Deltaic region in Bangladesh.
6.4 Geography, Geological Setting of the Bengal Deltaic
Coastal Region
Bangladesh is situated in the Ganges-Brahmaputra-Meghna Rivers catchments. The
deltaic coastal region of Bangladesh is located in the south of the country. The
coastal length is 710 km and the coastal area comprises 47,210 km

with a population of 36.8 million (BBS 1979, 1981, 1985, Islam 2016). There are 19 costal districts are included within the coastal region such as Jessore, Narail, Satkhira,
Khulna, Bagerhat, Gopalganj, Shariatpur, Chandpur, Pirojpur, Jhalokati, Barguna,
Patuakhali, Barisal, Bhola, Lakshmipur, Noakhali, Feni, Chittagong and Cox’s
Bazar (Figs. 6.1 and 6.2). The coastline of the Ganges delta extends from the month
