The history of JSIA dates back to 1997 when IAIA-Japan was established.
At that time, there were no national regulations governing Environmental
Impact Assessments(EIAs) in Japan. As such, local governments faced many
challenges implementing EIAs. Additionally, while there were some EIA-related
industrial associations, there was no EIA academic association. Subsequently,
IAIA-Japan was established in 1997 to offer EIA practitionaers and researchers
a forum to discuss both academic and technical issues. Another IAIA-Japan
objective was to facilitate international exchange both to learn lessons
from the experiences of other countries and to communicate Japanese experiences
to the world. IAIA-Japan played an active role until the establishment
of JSIA in 2002.
IAIA-Japan activities resulted in the establishment of the Japanese Environmental Impact Assessment Law in 1999. The EIA Law immediately and significantly changed the EIA scene in Japan. In particular increasing the technical complexity of EIA topics. The regulations also raised cumulative impact assessments, social impact assessments, and international cooperation. This created a necessity for a forum to discuss these issues on both a domestic and an international scale. Consequently, IAIA-Japan primarily comprised of EIA experts involved in international-scale projects, evolved into JSIA, comprised of both reserchers and practitioners from various disciplines and professions.
JSIA International Affairs Committe(JSIA-IAC) has had important missions to create opportunities of international relationships since it's established in 2002. JSIA-IAC has held the Fifth Japan-Korea conference, and the Sixth Japan-Korea-China triprate EIA conference.
