16. Discussion The WWF proposed solution for the basin: The WWF proposed solution for the basin: “Assessing whether new infrastructure is the best means of delivering the required service is the first step. If infrastructure is the best option, it should be planned to minimize impacts by: sitting off the river’s main stem and floodplains, mimicking natural water flows, allowing fish passage, controlling thermal pollution, and maintaining sediment and nutrient flows critical to sustaining the health of the rivers. Effective treaties between riparian nations to support integrated river basin management are essential for good governance.” What incentive do the countries have to follow these environmentally-friendly ideas?
