The search strategies looked for information on various aspects of ecohealth, planetary health and the environment, then applied a systematic review filter. The search strategy was compiled in the OvidSP Medline database and refined until the results retrieved reflected the scope of the project. It was decided to remove ‘air pollution’ from the search strategy as the recent WHO report provided adequate evidence for the impact of air pollution on health. 12 databases were searched during September and October 2014. They were: OvidSP Medline, OvidSP Embase, OvidSP Global Health, OvidSP Econlit,, EBSCO Africa-Wide Information, EBSCO GreenFILE, Biosis Citation Index, Web of Science Core Collection (containing Science Citation Index Expanded, Social Sciences Citation Index, Arts & Humanities Citation Index, Conference Proceedings Citation Index – Science and Conference Proceedings Citation Index – Social Sciences & Humanities), Scopus, OvidSP FTSA, Ovid SP CAB Abstracts, OvidSP AGRIS, OvidSP Geobase
