Filippo Menga is a Lecturer in Human Geography at the University of Reading, where he carries out interdisciplinary research exploring the interplay between humans and the environment. His research draws on political geography, critical water geography, critical geopolitics, and nationalism studies to advance an innovative approach to the study of water politics and develop three main and interrelated themes. The first theme relates to issues of scale, our understanding of the ‘political’, and the largely overlooked interaction between domestic and foreign politics in transboundary water relations. The second looks at how nationalism studies and matters related to the formation of a national identity can provide an explanation of water conflicts at the global level. The third theme focuses on global water governance, critically linking the current prominence of the water-energy nexus approach with the resurgence of the hydropower sector and the discursive shield of sustainability.
