Evidence Synthesis

CEE Evidence Syntheses take the form of systematic reviews and (evidence) maps providing rigorous and transparent methodology to assess the impacts of human activity and effectiveness of policy and management interventions. This website contains a fast growing Library of Environmental Evidence.

The Collaboration is not for profit and relies on the dedication and enthusiasm of scientists, policy formers, environmental managers and other stakeholders to provide a reliable source of evidence to continuously improve the effectiveness of our actions.
