Environmental impact of coal based power plant of Rampal on the Sundarbans (world largest mangrove forest) and surrounding areas

摘要

The 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.
