Abstract :
The land mass of Bangladesh has been formed by the deposition of sediments brought by the rivers Ganga and Brahmaputra and their numerous tributaries and distributaries. Ninety three percent of river water is brought into Bangladesh across the international border with India by 54 cross border rivers. Due to the abundance of water, fertile soil, very rich fish resources and cheap water transport people from many parts of the world started habitation in the Bengal Delta.
With the help of the International Community including Japan, the rural people of Bangladesh started becoming self reliant. But India has unilaterally started diverting Bangladesh water to the desert lands in Haryana, Rajasthan and Gujrat by constructing dams and other structures in the Ganga and the Brahmaputra basins. As a result the flow of the Ganga and its tributaries has been drastically reduced during the dry season from October – May when Bangladesh grows high yielding variety of rice (80% of total). India has also constructed several dams and hydraulic structures in the Brahmaputra basin thereby diverting Bangladesh water. As the result total production of rice in Bangladesh has been decreasing, natural fish habitats have been destroyed, vegetation has been wilting triggering desertification.
The reduction of flow in the Ganga and its distributaries has resulted in the intrusion of saline sea water upland. Sundarban forest, the largest mangrove forest in the world and which has been recognized as an important site of World Heritage by UNESCO, is being gradually destroyed due to salinity intrusion.
