Professor Rieu-Clarke's research interests lie in the interface between international law, sustainable development and transboundary waters. Alistair’s research has taken him to many of the major transboundary river basins in the world, and he has conducted several major multi-disciplinary research projects in Europe, Southern and Eastern Africa, Central America and South-East Asia.  Since September 2017, Alistair has been working as a legal advisor to one of the UN agencies responsible for the implementation of the SDGs, namely the United Nations Economic Commission for Europe (UNECE). As well as working for UNECE on SDG6.5.2 (transboundary water cooperation), Alistair has assisted in the implementation of the pilot reporting mechanism under the Convention on the Protection and Use of Transboundary Watercourses and International Lakes.
