The aim of the IV International Symposium on Transboundary Waters Management (TWM IV) is threefold:

* To assess the state of the art and the progress recently made in the sustainable management of transboundary waters by different disciplines such as law, socio-economics and water science.
* To review current major international programmes concerned with the assessment and management of transboundary water resources.
* To promote interdisciplinary approaches for integrated transboundary water resources management.

This fourth symposium will build on the experiences gained from the three previous symposiums (in Monterrey, Mexico in 2002, in Tucson, USA in 2004, and in Ciudad Real,, Spain in 2006), where water managers, policy makers, academics, consultants and representatives of international organisations and NGOs shared their experiences, technical advancements, knowledge and points of view relating to transboundary waters management.
