Climate change has an impact on the ability of transboundary water management institutions to deliver on their respective mandates‎.‎ The starting point for this book is that actors within transboundary water management institutions develop responses to the climate change debate‎,‎ as distinct from the physical phenomenon of climate change‎.‎ Actors respond to this debate broadly in three distinct ways ‎- adapt‎,‎ resist ‎(‎as in avoiding the issue‎)‎ and subvert ‎(‎as in using the debate to fulfil their own agenda‎)‎‎.‎ The book charts approaches which have been taken over the past two decades to promote more effective water management institutions‎,‎ covering issues of conflict‎,‎ cooperation‎,‎ power and law‎.‎ A new framework for a better understanding of the interaction between transboundary water management institutional resilience and global change is developed through analysis of the way these institutions respond to the climate change debate‎.‎ This framework is applied to six river case studies from Africa‎,‎ Asia and the Middle East ‎(‎Ganges‎-Brahmaputra‎,‎ Jordan‎,‎ Mekong‎,‎ Niger‎,‎ Nile‎,‎ Orange‎-Senqu‎)‎ from which learning conclusions and policy recommendations are developed‎.‎
