6. Professional Organizations Engaging in Landslide Study and Control Works

Japan Landslide Society

The Society was established in 1964, with a current membership of about 2,300 composed mostly of scientists and engineers working in the fields of geology, geomorphology, geophysics, civil engineering, erosion control, forestry, agricultural engineering, and other fields concerning landslides and related phenomena. Many of the members are affiliated with universities and colleges, research institutes, public agencies, consulting firms and other private sectors. The society has five sections representing five geographical regions of Japan.

The journal "Landslide" is published quarterly with over 120 published issues. To date, the journal contains mainly research papers printed mostly in Japanese and accompanied with English subtitles and abstracts.
Annual meetings are held in accordance with the by-law of the society, and generally attract about 1,200 participants and 100 to 110 papers are presented. In addition, the Society and its sections sponsor symposiums and workshops in various cities annually throughout Japan.
As for international activities, in 1972 the Society organized the first International Symposium on Landslide Control in Kyoto. The 2nd International symposium was organized in Tokyo in 1977, with the 3rd symposium in New Delhi in 1980. Thereafter, the symposium has been held once every four years, and in 1996 the 7th International Symposium on Landslides will be held in Trondheim.

The Society also joined and organized the "Landslide Field Conference" with American colleagues in 1979 and 1983 (in U.S.A.), 1980 and 1985 (in Japan) to exchange experiences, and the conference developed into an organization of International Conference and Field Workshop on Landslides (ICFL), which was supported by the United Nations, the U. S. National Research Council and other organizations. For the International Conference held in Tokyo in 1985, over 200 professionals participated and 81 papers were published in proceedings. This conference was continued and resulted in the 5th ICFL in Australia and New Zealand, 1987, the 6th ICFL in Milan, 1990, and the 7th ICFL in Bratislava, 1993. The 8th ICFL conference will be held in Granada in 1996. The Society also organized many International Workshops on Landslides with China and other countries of East Asia.

Forest Conservation Engineering Research Association

The Association was established in 1956 with forest conservation engineers as its members for enhancing forestconservation technology and developing business activities through the exchange of technical informations and the meetings for reading research papers.
The Association comprises the president served by the Director of Forest Conservation Division of the Forestry Agency and about 7500 members with 8 branch offices located across the country.
Activities of the Association include the publication of its journal for presenting research papers and exchanging view as well as the holding of meeting for reading research papers once a year. In addition, each branch office independently published journals and holds meeting for reading research papers.

The Japan Association of Landslide control Techniques

The Association was organized in 1974 by consultants and contractors engaged in landslide mitigation works and the manufacturers and dealers of materials, machines and instruments related to the mitigation works. The Association publishes a technical journal "Landslide Control Techniques", holds lecture meetings, and is increasing their efforts of mitigating landslide techniques, to study new control methods and develop new instruments.
