Academic programme & Technical work shops
Training of scientist and engineers during installation phase
(„Training on the job“), Workshop planned for Spring 2006,
eight PhD positions for applicants from IORC (“sandwich
programme”), Scientists exchange has started
Consultancy to organizational structures and inter-institutional
communication (government at different levels)
Advices for planning and construction of new infrastructures,
establishing of communication platforms and chains
Establishment of warning mechanisms within three pilot regions
GTZ staff in charge in Indonesia since summer 2006, training for
last mile actions in Padang, South Java & Kuta/Sanur (Bali)
