Ratification of 8 environmental agreements, 1974-2018

Sources: United Nations,; InforMEA,; FAO,


This series of graphs shows the dates when eight international treaties on the environment were ratified. Three conventions are old ones (over 35 years) which have only very gradually been ratified right up to the present day: they are those dealing with the trade in threatened species (CITES), wetlands (Ramsar), and the protection of migratory species (CMS). Two conventions in the 1990s were massively and swiftly ratified: one on biological diversity and the other to combat desertification. However, very few states have yet ratified the two treaties on genetic and phytogenetic resources.
