Ensuring sustainability of the rivers and ecosystems requires coordinated and collaborative action on the part of all countries, with the long-term goal of synergising political, social, cultural and ecological facets associated with the riverine system. Daunting as this challenge is, evidence suggests that a long-term view of transboundary basins is not very optimistic as big rivers of Asia contribute heavily towards urban and agricultural activities, and are experiencing challenges of increasing sedimentation, large-scale damming and pollution, among others . In the case of China, Sun et al.  have shown that the localised vulnerabilities within the Yangtze River basin prompt an 'integrated basin-wide approach' that is able to account for the specific needs of each of its sub-basins.
