Tongsuk Part 6 Symposium Recommendations VI Foreword The International Symposium on the Development of Small-scale Water Resources in Rural Areas was a major undertaking jointly implemented by the Carl Duisberg Gesellschaft - South East Asia Program Office (CDG-SEAPO), the Thai Ministy of Interior's Department of Local Administra- tion (DOLA), and the Faculty of Engineering of the Khon Kaen University (KKU). It convened representatives of national and international bodies, non-governmental organizations, donor agen- cies, academic institutions, and other professionals worldwide who are actively involved in small- scale water resources development. The Symposium effectively served as a forum for presentation and discussion of relevant examples of innovative small-scale water resources development projects/ programs, analysis of universal problems and bottlenecks as well as practical solutions to these, definition of possible paradigms of development which can guide future project planning, imple- mentation and management, and, most of all, fostering the exchange of information and experi- ences among participants. This publication documents the papers and posters presented during the Symposium as well as the overall Symposium recommendations. More importantly, this document extends one major Sym- posium objective of promoting exchange of information and experiences, by making available to other concerned people and organizations the relevant papers and results generated in this confer- ence. Gunter Tharun vn Acknowledgements The editors wish to thank all the authors of papers and posters that make this publication a rich source of information and insights, many of them offering truly innovative solutions to very challenging problems. Indeed they were instrumental to the shaping of the Symposium discussions and recommendations. The efforts of the Symposium co-implementing agencies, namely Khon Kaen University and the Department of Local Administration of Thailand, as well as the three Symposium Committees, namely the Advisory, Organizing and Technical Committees, are deeply acknowledged. They were the prime-movers behind the Symposium and it is to their credit as well that the material of this publication has been produced. Likewise, the editors are very grateful to Ms. Sangsuree Suree for her valuable editorial and compilation assistance. The editors are indebted to the German Federal Ministry for Economic Cooperation and Develop- ment (BMZ) for sponsoring the Symposium and the publication of the proceedings. Special thanks are due to the German Embassy in Bangkok, especially to H.E. Mr. Bernd Oldenkott, former German Ambassador to Thailand, for the enduring support and cooperation that they provided to CDG-SEAPO not only for this Symposium, but also for the umbrella project, the Thai- German Self-help Training Project on Small Water Resources Development in Rural Areas in Northeastern Thailand. vni Introduction and Keynote Speeches Introduction Symposium Background Water supply is at the core of developmental activities as it encompasses public health, nutrition, basic hygiene, and agricultural production. The scarcity of this resource is most acutely felt in rural agricultural areas in developing countries which are not reached by irrigation networks and drinking water utilities. In such areas, the development of small-scale water resources becomes a critical element for the subsistence and sustenance of economic productivity. In
