The Commission on Ecosystem Management (CEM) is one of the six scientific commissions of the International Union for Conservation of Nature (IUCN).

The IUCN CEM is a network of volunteer experts, numbering 1,000, from around the world working on ecosystem management-related issues, for example climate change adaptation, disaster risk reduction, Red List of Ecosystems, fisheries and ecosystem restoration and services.

The Commission works closely with other IUCN commissions, such as the Species Survival Commission and the World Commission on Protected Areas, as well as IUCN regional offices and global thematic programs. The IUCN Global Ecosystem Management Programme (EMP) is the focal program for CEM, which provides secretariat and technical support. Commonland staff are taking part in CEM’s thematic working groups on ecosystem restoration and business involvement. The international secretariat is based in Gland, Switzerland.

IUCN CEM is one of the founding fathers of Commonland. The Commission offers Commonland guidance and advice and gives access to IUCN’s worldwide database on ecosystems and network experts.
