On 18-19 March 2008 DLR organized a GPS training course for the WISDOM PhD scholars. The course was hosted by UNU-EHS in Bonn. In the theoretical and practical sessions of the two-day seminar the PhD scholars learnt to use GPS units and to process the acquired GPS data in a geographical information system. These skills will be necessary for the fieldwork which most of the PhD scholars will begin from April onwards. In addition, Prof. Dr. Evers presented first results of the research on knowledge clusters and knowledge hubs in the Mekong Delta.
