The initial research and structuring of relevant material for this publication was carried out by Stefanie Rothenberger, working as a research assistant with the Development Law Service from July through December 2003. Charlotte Oliver took over from Stefanie Rothenberger, working under contract with UNESCO and FAO. The high calibre of Ms Rothenberger's and Ms Oliver's professional input to the project is gratefully acknowledged. In addition, the advice provided by Jacob J. Burke, Senior Officer in the Land and Water Development Division of FAO, on points of hydrogeology issues was highly appreciated.
This publication would not have been possible without the support of the Secretariat of UNESCO’s International Hydrological Programme (IHP). Mention is also to be made of Raya Marina Stephan, UNESCO Consultant, for her help and advice.
