To establish a world-standard group for research and education on the “Active Geosphere”, based on Asia and Oceania where is the most active region

To create a new interdisciplinary “Active Geosphere Science” as a contemporary earth science, by expanding our field research mainly in Asia and Oceania further

Active Geosphere varies with time-scales of human activities, O( 1 sec) ~ O(103years), and covers the regions that are important for the sustainable coexistence of human beings on the earth, from the lithosphere to the upper atmosphere.

association with the research program Active Geosphere International Education Program a new type of education system for next generation graduate school

Education plan

Page 15: Organizations: Graduate School of Science Division of Earth and Planetary Sciences

Needs for fundamental understanding of the Active Geosphere : increase of interdisciplinary approach in the Earth science increase of interests on the nature close to ourselves in school education increase of societal actions to environmental and disaster-prevention issues

Field training of meteorological obs. ( DPRI ・ Shionomisaki )

Development of a new type of education system

for next generation graduate school

To respond to these societal needs : two-way education system with internet intensive field training course for a short period

Field training ofMeteorological obs.( RASC ・ EAR )

Page 16: Organizations: Graduate School of Science Division of Earth and Planetary Sciences

Creation of Active Geosphere Science from Asia and Oceania and education on Active Geosphere Science Promotion of contemporary earth science by organizing a melting pot of scientists Important role as a prognostic earth science for settlement of global environmental issues

Scientific contributions & societal impacts

Goals

1. Creation of Active Geosphere Science

2. The newest scientific results from Asia and Oceania
