This study is intended to contribute to the discussion of international freshwater governance, in particular with respect to how regional and basin agreements relate to the implementation of international water law principles and provisions and to global multilateral environmental agreements (MEAs). More specifically, this study examined how seven regional and basin water agreements deal with selected international water law principles and provisions and how that treatment relates to the implementation of the United Nations Convention on the Non-Navigational Uses of International Watercourses (the UN Watercourses Convention) and seven other MEAs.
