What to do about Amazonia? Brazil Perspectives Comprehensive, ecosystem-based approach to managing waters and their drainage basins. Integrate the lessons learned from earlier experiences to achieve better results. Work with neighbors countries (eg. Bolivia, Peru) to develop joint water development projects.

Lessons for the future
Questions for discussion Development in the Amazonia Basin region is just beginning and it has been compared to the 19th-century “wild west” of the United States. The rich hydrology of the region presents an opportunity for several water and hydropower related projects. Do you think a global policy or recommendation should be adopted in order to limit the number of projects (Dams, waterways) for this region? How can future projects avoid the mistakes made in older water projects?
South America - Amazon Basin Thank you.
