Science and technology in Benin in this database in 2014. This compares with 65.0 per million for Gambia,49.6 for Cabo Verde, 23.2 for Senegal and 21.9 for Ghana. The volume of publications in this database tripled in Benin between 2005 and 2014 from 86 to 270. Between 2008 and 2014, Benin's main scientific collaborators were based in France (529 articles), United States (261), United Kingdom (254), Belgium (198) and Germany (156). Several regional research centres have been set up since 2002 that are hosted by West African countries. Benin's participation in these centres should help it to develop science and technology.
