This Note assesses international river law’s role in shaping transboundary river governance, both generally and in the specific context of the Amu River basin. The main argument presented is that the United Nations Economic Commission for Europe (UNECE) Water Convention and the U.N. Watercourses Convention are ineffective in curating inclusive and equitable transboundary river governance frameworks, as their values and goals fall short of the vision espoused by the Stockholm Declaration. In the specific context of the Amu River basin, states use the gaps inherent in these conventions to advance and justify their individual interests over the collective good. This Note begins by providing a brief history of international environmental law before moving on to compare the ideas enshrined by these conventions and those safeguarded in the Stockholm Declaration. The Note then turns to the Amu River and examines how the riparian states engage with the UNECE Water Convention and U.N. Watercourses Convention.
