It was the third international symposium on sago to have been held in Japan, supported by the Japanese Society for Tropical Agriculture (JSTA); the Japanese Society of Applied Glycoscience (JSAG); United Nations of Food and Agriculture (FAO) Regional Office for Asia and the Pacific; the Ministry of Agriculture, Forestry and Fisheries of the Government of Japan (MAFF); Japan International Cooperation Agency (JICA), the Japan International Research Center for Agricultural Studies (JIRCAS), and Rikkyo University. About 120 participants including 78 sago spe- cialists from many countries in the world came to Ikebukuro to participate in the symposium. Through the discussion during the symposium, it was concluded by the organizing committee of SAGO 2015 that a book on sago should be published by the Society of Sago Palm Studies from the viewpoint of new aspects. The society contacted Springer Publishing Company to publish a book on sago. Much of the contribution for this book was financially supported by the late Isao Nagato and Rikkyo University, which accepted the financial proposal from the society. Sago palm (Metroxylon sagu Rottb.) can be grown in wetland swamps of Southeast Asia and the Pacific islands where other food crops cannot grow eco- nomically and produce high yield of starch. It is one of the typical indigenous food crops with very little attention and research. Since other food crops cannot be grown, sago palm has a high potential to contribute to food security and improve- ment of health and human welfare as an additional source of staple food without competition for the use of arable lands. Sago palm can absorb a large amount of carbon dioxide to counteract global warming and climate change and grow up to 20 m in height, accumulating starch in its trunk. Few people know that Japan has imported around 20,000 mt of raw sago starch from Malaysia and Indonesia for more than 20 years. Sago starch is typically v vi Preface used as dusting starch in Japan. Sago starch granules are relatively large and uni- form, making them ideal for the separation of adhesive noodles but more costly than cassava starch. Accordingly, sago starch always has a competitive price compared to cassava starch in the world trade market. The late Dr. Isao Nagato supported sago studies based on his belief that sago palm will strongly contribute to solving the food crisis in this century and invested large sums of his funds in sago palm and related research. He established the foun- dations of sago palm research in Japan to promote sago palm research for young scientists. As a result, Japan has come to lead in international research on sago, even though no growing areas of sago palm naturally are present in Japan. He recognized the potential power of sago palm in vast tropical lowland areas with brackish water. The late Dr. Isao Nagato We acknowledge all of the contributors of this book and Springer Publishing Company and hope that this book is useful to sago researchers and serves human and planet welfare.
