“…International rivers constitute an important natural resource shared between neighbouring countries. Looking back in history, transboundary cooperation over international rivers has been the norm rather than an exception on a variety of issues such as flooding, pollution, navigation and water resource allocation (Bernauer, 2002;Bernauer & Kalbhenn, 2010;Le Marquand, 1977;Marty, 2001;Schmeier, 2010;Van der Zaag, 2007;Verwijmeren & Wiering, 2007;Wolf, 1998).
