“…More or less similar observations were also made by [22][23][24][25] recorded dolphins, crocodile, Maskedfinfoot, migratory birds, wild boar, deer, snakes, fishes, different mammals etc. inside the Sundarbans, in and around the rivers and their connected canals and creeks of the Sundarbans.…”

Government has acquired 1,834 acres of agriculture land in Satmari-Katakhali and Koigordashkathi areas under Rampal upazila to establish the power plant. Only 86 acres lands are kash land and rest of the lands are public lands which were used for rice and fish cultivations by the land owners. The government has also taken an initiative for dredging 10 kilometers of the Poshur river to allow easy access of ships carrying coal for the plant. 8,12 Due to an inadequate supply of local coal, the operator suggests to use imported coal. The Bangladesh AbstractThe physico-chemical conditions of air, water and soil, and biological conditions of the proposed Coal based Power Plant area (Rampal), Mongla and the Sundrabans were studied from August 2011 to July 2013 to assess the possible environmental impact on the Sundarbans and surrounding areas. Environmental Impact Assessment (EIA) of physical, biological, social and economic environment of the study areas indicate that most of the impacts of coal-fired power plant are negative and irreversible (-81) which can't be mitigated in any way. It is indicating that climate, topography, land use pattern, air and water quality, floral and faunal diversity, aquatic ecosystems, capture fisheries and tourism of the Sundarbans and the surroundings areas would be affected permanently due to proposed coal fired power plant. Increasing of water logging conditions, river erosion, noise pollution and health hazards; decreasing of ground water table; loss of culture fisheries, social forestry and major destruction of agriculture would be happened due to coal fired power plant. The benefits of proposed coal fired power plant of Rampal is very poor (S+19) than that of negative irreversible impact (-81). So the proposed area is not suitable to establish the coal based power plant as the Sundarbans and surrounding areas would be affected permanently by establishing the proposed coal power plant. government has decided to bring coal inside the Sundarbans through the Mongla sea port. Indian National Thermal Power Company and Bangladesh Power Development Board are the two signatories of the project. The proposed power plant will burn around 4.75 million tonnes of coal annually when more or less 0.71million tonnes ashes and around 0.5 million tonnes sludge and liquid waste may be produced (CEGIS 2013). It would also emit a good amount of carbon dioxide (CO 2 )-key factor for global warming -some other toxic gases and airborne particles, according to Union of Concerned Scientists, a USA-based group. 5,12 Discussed on the types and levels of pollution of coal-fired power plant. The ground water and water of the Poshur river may be polluted by the huge amount of waste produced due to burning of the coal. Whereas the existence of strict laws to protect the environment and the wildlife, the government has recently decided to declare a part of the Poshur and Andharmanik rivers sanctuaries for dolphins (Sankar 2012). Due to the Ecologically Critical Area (ECA) rules no power plant should be set up with...

“…Q90 and Q95 for both rivers show a similar decreasing trend (Figures and ) with Q95 being the most commonly used flow statistic to assess downstream water quality (WMO ; Bojinski ). A drastic reduction in Q95 with the ongoing construction of Rampal coal‐fired power plant (Chowdhury ; Lemly ), located 9 km downstream to Sundarbans, indicates a potential threat to its ecosystem especially for water quantity and quality.…”

The Ganges Delta in Bangladesh is an example of water‐related catastrophes in a major rural river basin where limitations in quantity, quality, and timing of available water are producing disastrous conditions. Water availability limitations are modifying the hydrologic characteristics especially when water allocation is controlled from the upstream Farakka Barrage. This study presents the changes and consequences in the hydrologic regime due to climate‐ and human‐induced stresses. Flow duration curves (FDCs), rainfall elasticity, and temperature sensitivity were used to assess the pre‐ and post‐barrage water flow patterns. Hydrologic and climate indices were computed to provide insight on hydro‐climatic variability and trend. Significant increases in temperature, evapotranspiration, hot days, heating, and cooling degree days indicate the region is heading toward a warmer climate. Moreover, increase in high‐intensity rainfall of short duration is making the region prone to extreme floods. FDCs depict a large reduction in river flows between pre‐ and post‐barrage periods, resulting in lower water storage capacity. The reduction in freshwater flow increased the extent and intensity of salinity intrusion. This freshwater scarcity is reducing livelihood options considerably and indirectly forcing population migration from the delta region. Understanding the causes and directions of hydrologic changes is essential to formulate improve water resources management in the region.

“…To manage Sundarbans mangrove, detailed work plan was first prepared in the year 1893-1894 (Chowdhury and Ahmed 1994). After that, a working plan was prepared to manage the forests based on the inventory of Sundarbans in period of 1960-1980(Choudhury 1997. In 1993, forest master plan was prepared, which recommended two sanctuaries.…”

“…Recently, a management plan for the protection of Sundarbans is being prepared by Food and Agricultural Organizations (FAO). The aim of this project is to achieve sustainable management of mangroves in order to utilize forest resources (Choudhury 1997). In recent times, forest cover, species diversity and ecosystem function have declined rapidly, although a number of guidelines (Table 10) exist to protect the forest resources.…”

Sundarbans are highly productive mangrove wetland ecosystems, contributing several social, financial and environmental benefits. The forests have a great role in the countries national economy, and provides livelihood for the local people through fishing, tourism, wood and non-wood products. But despite several laws, policies and management plans, the forest is now showing clear signs of degradation. The aim of this study is to explore the major causes of degradation of Sundarbans mangrove forest in Bangladesh and to propose a management approach for its sustenance. It was found that, biodiversity and ecosystem of the Sundarbans is threatened due to several natural and human induced pressures, including overexploitation of forest resources, changes in coastal land use, pollution from industrial and agricultural sources, oil spillage, upstream water flow reduction, increased salinity level, disease outbreaks, fire occurrence, climate change, rise in sea level, natural disasters, lack of knowledge about forest conservation, uncontrolled tourism, inadequate planning and management, and increase in man-animal conflicts. In this background, an integrated approach is proposed, by refining the existing management and combining updated information through supplementary scientific studies and expeditions on mangrove forests. Proper implementation of the proposed resilient strategies i.e., incorporate all stakeholders to protect the forest, awareness programs, reduced forest dependency of local people, strengthen monitoring, ecological restoration, implementation of legal bindings, disaster management and adequate research and planning can be helpful for sustainable management of Sundarbans and similar mangrove forests around the world.
