Our Mission: To provide expert guidance on integrated approaches to the management of natural and modified ecosystems to promote biodiversity conservation and sustainable development. CEM has identified 13 themes as programmatic priority for 2017 – 2020 in its intersessional plan. Each theme has a group of experts working on issues related to it and has a Thematic Group Leader facilitating the group’s composition and functioning. Thematic groups can be joined by experts through our CEM application process.
