The Joint Workshop of the Basel Convention and Stockholm Convention Regional and Subregional Centres was held between the 28th of September and 2nd of October 2009 in Geneva. Over the course of the week, participants recognised various areas of future cooperation and coordination and emphasis was laid on 'training the trainers' where the secretariats provided practical information and tools to the Centres to improve their delivery in their respective regions. Active participation by the Directors and Centre's staff further enhanced the quality of the workshop.
