Abstract
Developing the Mekong as an inland waterway, linking the six riparians, has identified as a necessity to boost the fast growing economies of the region. Sedimentation, associated with extreme deforestation of the basin has obvious negative impacts on the river ecosystem. Navigation development activities should be carried out with utmost care not to jeopardise other uses of basin's resources. The objective of this study is to focus attention on water management issues with particular emphasis on identifying environmental impacts associated with improvement of inland navigation in the Mekong.
