Extensive literature has shown the impact of water scarcity discourses on national policies, however the impact of water scarcity discourses on transboundary water governance has been overlooked. With this article Hussam Hussein contributes to filling this gap by investigating the impact of the water scarcity discourse in the case of Jordan, specifically on three cases of transboundary water governance: the Yarmouk River, the Jordan River and the Disi Aquifer. This article shows that the water scarcity discourse is not enough to explain transboundary water governance, as it needs to be contextualized in the broader context, considering national security, regional geopolitics, inter-sectorial interests, and power asymmetries. This is particularly true when considering that the Arab region has most of its surface waters originating outside of its countries, and transboundary waters represent over two thirds of its overall water resources. click here to purchase the article.
