Well, it finally happened. On 19 May 2014, Vietnam became the 35th party to the 1997 UN Convention on the Non-navigational Uses of International Watercourses. This means that on 17 August 2014, 90 days after that 35th ratification was deposited, the Convention will come into force.
Long in coming, the Convention’s success was never guaranteed. Adopted by the UN General Assembly in 1997, the Convention appeared set for ratification as 103 of the UN’s Member States voted in favor of it. Only three countries voted against – Burundi, China, and Turkey – while 27 nations abstained and 33 were absent from the vote. That vote, however, masked long-standing disagreements over how transboundary fresh water resources should be allocated and managed. In particular, upper and lower riparians disagreed between the primacy of the Convention’s cornerstone principles of equitable and reasonable use – favored by most upper riparians – and the doctrine of no significant harm – preferred by most lower riparians.
Lackluster support in the years following the Convention’s inception suggested to some that the treaty was doomed to failure. More recently, though, the rate of ratifications more than doubled (18 in the first 12 years in comparison to 17 over the past five years). While that resurgence may have been due, in part, to the efforts of World Wildlife Fund (which in around 2009, added implementation of the Convention to its advocacy agenda), it also suggests a broadening recognition that nations have an obligation to cooperate over transboundary freshwater resources. Maybe it’s the threat of climate change, or concerns over dwindling domestic water resources. But, the fact that states are willing to bind themselves to the procedural and substantive norms of the Convention is a promising sign.
