The Jane Goodall Institute (JGI) with technical support from the Wildlife Conservation Society (WCS) held a two day workshop at the JGI’s Education Center in Kigoma on 23-24th of May 2013 to expose conservation managers, planners, members of the development community and government to these relatively new tools and how they can be used to make better decisions for all concerned. The team aimed to do this through analyzing a case study of the trade-offs between biodiversity conservation, carbon sequestration and development in the Greater Mahale Ecosystem in western Tanzania.
