Bay of Bangal Large Marine Ecosystem Bangladesh

Ecosystem Health

Despite a limited area and a population over 150 million, Bangladesh has not hitherto paid adequate attention to environmental degradation and pollution which are, at present, affecting the coastal and marine environment and its major protein resources. Coastal and marine pollution mainly results from the crude oil (PAHs) transportation systems, water oil from different sea cargo, ships and mechanized vessels, workshop, refinery handling loss, dumping of ballast and bilge water, TBT, PCBs, DDTs, Dioxins, Furans etc. Besides, more than 50% of the marine oil pollution comes from urban activities and through river run-off. In addition, a number of accidental spillage or discharge of crude petroleum are also reported at the coast of Bay of Bengal, Bangladesh or recent offshore hydro carbon drilling operation in the EEZ of Bangladesh is a factor of marine pollution. One of the most serious impacts is the decline in estuarine, coastal/marine water quality caused by rising levels of nutrients from land-based sources. Besides, the Ganges-Brahmmaputra-Meghna river basin is the major recipient of waste from industries in Bangladesh and India which drains down in to the Bay.

Regional BOBLME Project assisted in formation of working groups from the member countries and supported the WGs (including Bangladesh) to participate in the BOBLME Working Group Meeting on Ecosystem Indicator and 1st Int. Conf. on Managing Ecosystem Health of Tropical Seas "ECOSEAS'10" conference in Malaysia during 19-22 October 2010 to identify and participate in selection of indicators, its template (regional and national) to assess the status (Environment & Fisheries) of the BOBLME. The WG also reviewed practices on existing ecosystem health indicators and quality indicators and standards and their application in the BOBLME. The indicators will need to be developed for all five LME modules (i) productivity, (ii) fish and fisheries, (iii) pollution and ecosystem health, (iv) socio-economic and (v) governance. It also agreed that the indicator set should be compatible with the indicator set being developed by the Global Environment Facility (GEF) Transboundary Water Assessment Programme (TWAP) that will be used as a common method to assess and compare the world's LMEs. The indicator set would be used in assessing changes in the state of the environment, the human activities and their associated stress the change in ecosystem goods and services and the governance covering the management arrangements.
