Assessment of the socio-economic value of freshwater species for the northern African region

This project aims to assess the socioeconomic value of freshwater species across the northern African region within the context of the threats to those species as previously determined and documented by the IUCN Red List of Threatened Species. The aim here is to link IUCN Red List data on the extinction risk for 877 species across northern Africa with information on these freshwater species’ socioeconomic value, and to evaluate levels of dependence on wetland services in conjunction with the known threats faced by the species underpinning these services.
