The methodology of the Transboundary Waters Assessment Programme for river basins proposed by the United Nations was used to evaluate risks within current and future scenarios. The results obtained allow the inference that the River Plate basin is in a moderate-risk category. However, high and very high risk values were observed for the pollution, dams and economic reliance indicators, which in the future horizon could promote conflicts regarding water resource use. In conclusion, states should establish their priorities and clear rules for monitoring, use and surveillance of water. This process should be done in an integrated manner, with due regard for international arrangements, and should be compatible with the policies and management instruments of the countries involved.展开更多

To evaluate risks, two scenarios (current and future) were simulated using the methodology proposed by the Transboundary Waters Assessment Programme River Basins. The results obtained allowed the inference that the Amazon Basin, considering all indicators, is in the “moderate” category of risk within the current scenario. In turn, when only the “governance” indicator is considered, reflected through projected water politics tensions, the risk category for the basin becomes “high”, both in the current and future scenarios (2030 and 2050). In conclusion, it is recommended that states should establish clear priorities and rules for water resource monitoring, use and supervision.展开更多
