Of all the mechanisms included in water governance, this is the most prevalent and also remains among the most difficult to carry out. Others, however, are political and often appear when the government of one country, usually an upstream country, embarks on river-related projects that are likely to have significant downstream impacts in other countries. Water diversion, dam construction and waste disposal in water are examples of types of activities that are in need of assessment but, when cross-border relations are involved, are not shared, either by lack of concern about cross-border impacts or unwillingness to be open to potentially critical assessments from outside the country. Similarly, information is not only about projects and their impacts, but also about decision-making, especially with regard to behind-closed-doors agreements that can entail corruption.
