On 22 March 2011, Burkina Faso acceded to the 1997 UN Convention on the Non-navigational Uses of International Watercourses. There are now 23 parties to that instrument (see Status of the Convention). This comes on the heel of France’s accession just last month (see my post on this here), as well as the accessions/ratifications by Greece, Guinea-Bissau, and Nigeria in 2010.
According to Article 36(1) of the Watercourses Convention, it “shall enter into force on the ninetieth day following the date of deposit of the thirty-fifth instrument of ratification, acceptance, approval or accession with the Secretary-General of the United Nations.” That day may be coming soon.
