What is ILTER?

Networks of scientists engaged in long-term,site-based ecological and socio-ecological research.
EUN America
１９９３

EAP

C/S America

S Africa

5 reg. networks
43 countries

ILTER’s Mission:

Improve understanding of global ecosystems and inform
solutions to current and future environmental problems.
Goals:• Foster and promotecollaboration andcoordination among
researchers at all levels• improve comparability oflong-term ecological data
• deliver scientificinformation（GO BON) and• Facilitate education

CHALLENGES

1. Site: site selection, management, and maintain
2. Research & Technology: capacity, user needs andcurrent issues (CC, SDG, social dimension, etc)
3. Education & Outreach: limited use for amongscientists
4. Information System: non-standardized, labor
intensive and sharing
5. Publications: quant. & qual. (grey literatures)
6. Leadership: build on the legacies
Synthesis: ES-Kim, King, Hiroyuki

DIRECTIONS

1. Site management & Infrastructures- representecosystems, supersite concept, funding
2. Research: integrate social science, address
current issues/needs, cross-site, local -global
3. Education & Outreach: hands-on sciencelearning for K-12 students, Uni., CSR activities
4. Information System: IMS, data sharing
5. Leadership: Continuation and participation
6. Others: Network of networks, in-situ & satelliteobs., global contribution, etc
