This event is organized in conjunction with four other adjoining events, the Regional Steering Committee Meeting of the IHP-UNESCO National Committees for the Asia Pacific Region, the 3rd Asia Pacific Training Workshop on Ecohydrology, AP-Friend chapter-2, and the rumual meeting of the Scientific Advisol)' Committee on Ecohydrology, all are held as parallel sessions in Bali, Indonesia, during 23-26 November 2005. The intemati<:mal symposiwn will organize paper presentations on eight topics related to developments in ecohydro l o~:,>y or"the Asia Pacific region. They are: o Ecohydrology, spatial plruming, land cover and land use changes o Erosion and sedimentation trails o Water quality and envirorunental sanitation o Climate variability and ecohydrology o Water, culture, and religion o Water policy ar1d good governance o Best management practices o Hydrology and water resources This volume contains 46 papers that are presented during the two days deliberations. Not all the papers can strictly follow the organizing committees guidelines for not more than seven pages, there are papers with more pages. Due to communication problems and the limited time, we were not able to cut or rewrite the papers to less than 10 pages and have kept as it was. This international meeting is held at an early stage of ecohydrology developments in the Asia Pacific region. For this, there is a wide range oftopics, dispersed and not well-distributed group of papers presentation, which was unavoidable. The outcome Of this Bali meeting is expected to select and decide for a better­ concentrated group of activity that could be plrumed for the coming two years. It is a real pleasure of having papers from various countries in the Asia Pacific region to be presented in this event. There is a wide range of climate variability in the region, topography and tectonic differences, island­ small island-continental countries, transboundacy river basins, different social and demographic background, as well as the physical stage of developments in the member countries. With this diverse background it is really expected that there will be cross countl)'/region enrichment in ideas, dialogue, and exchange of experiences. We hope that this initiative of an international ecohydrology meeting and its deliberations will bring benefits to many of us. Contacts could be chrumeled through the UNESCO umbrella and regional organization to facilitate the challenges and problems faced by scientists in the Asia Pacific region.
