System dynamics is a way to look at the complex physical and social systems around a particular problem. It can be used to design policies to improve how the systems work (thus reducing the problem). CIFOR scientist Carol Colfer believes that system dynamics modelling can help address natural resource problems in developing countries, including those related to climate change. And in the process, the perspectives of the most marginalised groups should be sought out and included. Colfer presented this PowerPoint at the annual System Dynamics society meeting, held in Washington, DC in late July 2011. Her presentation (prepared with system dynamicist, Richard G. Dudley) encourages system dynamics practitioners to use their skills for climate change adaptation and mitigation; and provides guidance for incorporating the views of marginalised people.
