Wind-blown sand in Beijing
Desertification around Loess Highlands

in Fukuoka(Japan)
Loess Highlands
Father Zhu and his colleagues are very successful by folkway forestation
-> Grid Computing with GLOBUS Security Infrastructure
Connection of IPv6 local networks

•Normal position of certification files /etc/grid-security/
•Position of certification files for field servers /server-A/etc/grid-security/ /server-B/etc/grid-security/ /server-C/etc/grid-security/ …….
•Switch of certificates by chroot command /server-A/etc/grid-security/ “chroot /server-A” is accessed as if it were in /etc/grid-security/
Switch certificates by chroot command
A’s Server Certification

B’s Server Certification

Future Plan
•Introduction of Metbroker.
•Monitoring of septic tank system.
•Locate field servers in forestation fields.
•Design and localization of forestation and agriculture logging system.
•Locate camera servers in temples for culture promotion.
