Analyzing the critical locations in response of constructed and planned dams on the Mekong River Basin for environmental integrity

Abstract

Abstract Massive hydropower dams in the Mekong river basin (MRB) have triggered substantial debate and international attention due to its utmost importance on maintaining ecology and biodiversity. Although numerous studies have been conducted to assess the consequences of existing and proposed dams, the combined effects of dams on biodiversity and ecosystems have received limited attention. In this study, we focused on the dam’s locations and suitability on the overall Mekong River Network in order to comprehend the environmental and ecological integrity of the MRB as a whole. Overall, we identified harmful dams on their associated sub-basins based on the notion of connectivity. The vulnerability of ecosystems and biodiversity in the MRB is well recognized, and our findings generally provide additional theoretical support for their protection.
