Sago is a promising plant in 21 Century. It can grow in lowland soils of Southeast Asia and Melanesia
and support the people in these areas. Sago biomass, including starch, bark, leaves and others, is usefulfor various purposes. Sago starch especially, which is produced in Indonesia, Malaysia, Thailand, thePhilippines, Papua New Guinea, the Solomon Islands and other countries, amounts to 400 thousand tons
per year and is used variously for food and processed food or floured for noodle making and others.
Although the sago starch has been consumed mostly in the areas producing sago starch, Japan has been
importing over 20 thousand tons of sago starch every year from Malaysia and Indonesia, previously as
dusting flour and recently as excellent food material for allergy relief.
The 1st International Sago Symposium (ISS) was held in Kuching of Malaysia in 1976. With three tofour years interval, ISS has been hosted mostly by sago producing countries. Japan hosted ISS in 1985
(SAGO –’85, Protect Mankind from Hunger, and the Earth from Devastation), 2001 (SAGO 2001, NewFrontiers of Sago Palm Studies) and 2015 (SAGO 2015, The Sago Supports Human and Planet Welfare).
The proceedings of these symposiums and a book entitled “Sago Palm: Multiple Contributions to Food
Security and Sustainable Livelihoods” compiling invited papers were published with the support of thelate Isao NAGATO, who encouraged our activities through his perspective.
In 2023, the Society of Sago Palm Studies is pleased to host a meeting as the 14th International Sago
Symposium.
We hope the strong support from you.

Objectives
The objective of symposium is to discuss about continuity of harvesting sago which maintains the aspectof conservation, social and culture in achieving the sustainable development goals.
ISS 2023 becomes a media for communication and discussion among researchers /engineers,environmentalist, sago business practitioners, and other stake-holders in order to:・Utilize SAGO as sustainable bio-resources which maintains the aspects of conservation, social andculture
・Make SAGO as competitive and parallel commodity with other plant commodities in the view ofproductivity and quality
・Find a proper way and solution to convert natural SAGO forest to production forest while conserving
the genetic resources inside・Develop SAGO business considering the sustainability of sago forest

Scope of Symposium
The symposium will deal with state-of-the-art of sago study and will facilitate exchange of sago
information among the participants, hereby will make sago to become a flagship crop for staple food,ingredients to prevent allergies, industrial raw material as well as for energy. The symposium will be
divided into four thematic sessions:・Biology, Agronomy and Environment
・Industry and Utilization
・Business and Economy
・Social Sciences and Anthropology

Who should attend
・Scientist, researchers, university and academics
・Private sector and business practitioner
・Government institutions, international organizations and policy makers
・Non-Government organization
