Other effective area-based conservation measure (OECM)

The Kunming-Montreal Global Biodiversity Framework, adopted in 2022, provides a framework for the effective implementation of the Convention on Biological Diversity (CBD) through four goals and 23 targets. Target 3 (known as the ‘30x30 target’) calls on Parties to conserve at least 30% of terrestrial, inland waters, and coastal and marine areas by 2030. These guidelines are designed to promote good practices relating to identifying, reporting, monitoring and strengthening OECMs.

Other effective area-based conservation measures (OECMs) are sites outside protected areas that deliver effective and long-term in situ conservation of biodiversity. Biodiversity conservation may be the primary objective of the site, a secondary objective of a site that is managed for other purposes, or it may be an unintended consequence of the way the site is managed.

Inland waters – such as rivers, lakes and other wetlands – are among the most biodiverse ecosystems on the planet. They are also the most threatened; almost one in three species is at risk of extinction and monitored populations of freshwater species have declined by 85% since 1970. The loss of these ecosystems has cascading effects on human livelihoods, cultures and our overall well-being.

Many protected areas worldwide overlap with ‘territories and areas conserved by Indigenous peoples and local communities’ or ‘ICCAs’ (Indigenous peoples’ and community conserved areas’). These overlapped ICCAs include conserved commons, sacred places and Indigenous and community protected areas.
