IUCN WCPA Technical Note Series No. 6
RECOGNISING AND REPORTING OTHER EFFECTIVE AREA-BASED CONSERVATION MEASURES
This Technical Note provides a summary of the following Technical Report,
‘Other effective area-based conservation measures’ (OECMs) are areas under different governance and management regimes that deliver the long-term in-situ conservation of biodiversity. Although first mentioned under Aichi Target 11 in 2010, it was not until 2018 that Parties to the Convention on Biological Diversity adopted the following definition for an ‘other effective area-based conservation measure’ (OECM): “A geographically defined area other than a Protected Area, which is governed and managed in ways that achieve positive and sustained long-term outcomes for the in situ conservation of biodiversity, with associated ecosystem functions and services and where applicable, cultural, spiritual, socio–economic, and other locally relevant values” (CBD Decision 14/8).
