The piece outlines the contributions of key works in the field of the political ecology of desalination over the past decade. We note that the field is diverse in terms of contributions from geographers, sociologists, anthropologists, and public policy scholars. The research to date has been concerned with the ways in which the deployment of desalting techniques can reflect and reinforce social processes of inequality, political power and economic flows. In this way, desalination has been opened up for intellectual debate beyond technical considerations of the desalting industry and engineers. A critical perspective that complements the recent discussions of environmental harm caused by the desalination industry has emerged as well across a number of global and transboundary contexts. A number of themes emerged that will continue to be of interest to scholars and that need to be addressed in the years ahead. First, desalination intersects transboundary water governance and geopolitics between different water uses and emerges from complex assemblages of local and global actors, including financial actors, water companies, governments, technologies, and natural forces. Second, critical scholarship on desalination needs to continue to pay attention to the interests in and overarching patterns of, the Green New Deal and Blue Economy, each of which intersect with the worlds of academia and policymaking, and involve issues of climate adaptation and mitigation. Third, questions about equity remain with desalination as it is a solution deeply imbricated in the unequal distribution of resources, and questions about representation in decision-making remain. Fourth, research on finance and infrastructure have been at the core of critical desalting research and should remain so. Fifth, there is a growing heterogeneity in terms of research in types of desalting, from reverse osmosis to inland desalting to nuclear and more. This variety will make for rich research for the years ahead. Our hope is that the epistemological, theoretical, and methodological flexibility of this area of research will remain a strong point continuing its rigor, as well as the already robust collegiality among scholars in this interesting, and still nascent field.
