'Political ecology is going international! In this path-breaking book, the authors demonstrate beyond reasonable doubt how environmental conditions, in particular water and climate, co-shape international political (in)security. Drawing on the traditions of political ecology and international relations, the authors carefully weave a tapestry of sophisticated conceptual argumentation and detailed empirical analysis that opens the way for an urgently needed international political ecology. Divided Environments should be taken very seriously indeed by anyone concerned with how environmental conditions intersect with questions of political power, inter-state relations and socio-ecological (in)security.'
