GEF annual impact report 2008 (English)

The annual impact report 2008 brings together the results of two interrelated approaches that explore the value of using quasi-experimental methods to construct accurate counterfactuals for project intervention areas. In the current cases, these approaches establish the outcomes had protected area systems not been created. While such quasi-experimental studies are interesting and provide insights into what is happening in a well-structured and rigorous way, the office's main methodology for tackling impact questions is a theory-based approach, which aims to unwrap and evaluate the assumptions of why project interventions are supposed to achieve impact on the global environment.
