What is CEEDER?

CEE is developing an open access evidence service to help decision makers find reliable evidence reviews and syntheses to inform their decision making. The CEEDER database lists available (commercially published and ‘grey’) syntheses of primary research (e.g. critical reviews, meta-analyses, systematic reviews) conducted to assess evidence on a specific question of environmental policy or management relevance. Most importantly the database provides an independent assessment, conducted to preset quality criteria, of the reliability of each synthesis with respect to its use in decision making. Presentation of the assessment is tailored to the needs of decision makers/evidence users in governmental, non-governmental and private sectors.

CEEDER scope:

CEEDER contains research syntheses relevant to decision making in all areas of environmental management and policy. The service is global in scope and we collate the reviews using regular systematic searches or relevant databases and search engines. The service started with  reviews published in 2018. Collated reviews are checked against eligibility criteria and the database contains only reviews that claim to make some form of quantitative assessment of impacts on the environment or effectiveness of interventions that would be of direct interest to management or policy.

How the service works:

Each synthesis is appraised for its rigour and reliability using an objective 4-point scale. Research syntheses gain credit both for their rigorous conduct and transparent reporting as well as the quality of the primary data and the synthesis itself. Consequently, it is not strictly the scientific merit being judged but the reliability and utility of the synthesis findings for decision making. Syntheses are scored in the context of the question(s) they address.

How the service can be used:

Faced with a decision or question that might be informed by evidence the user can search for relevant syntheses using a simple keyword system (a guide to searching will be provided). Syntheses of potential relevance will be listed together with their ratings for reliability. The user can then choose the most relevant and reliable syntheses, taking note of their limitations. Links will be provided to the location of each synthesis article (Please note: CEEDER cannot provide access to the full text of articles for copyright reasons and therefore a subscription may be required).
