Call for nominations of experts for second global assessment of biodiversity and ecosystem services | deadline: 28 March

The overall objective of the second IPBES global assessment of biodiversity and ecosystem services (“the second global assessment”) is to assess relevant knowledge that has become available since the publication in 2019 of The Global Assessment Report on Biodiversity and Ecosystem Services and to assess progress towards achieving the goals of sustainability and living in harmony with nature. The second global assessment will strengthen the science-policy interface on biodiversity and nature’s contributions to people on a range of spatial scales, from the local to the global, by providing the knowledge and the policy support tools needed for informed decision-making. The second global assessment will be delivered in 2028.

Call for experts

In line with decision IPBES-11/1 and the procedures for the preparation of IPBES deliverables, the Multidisciplinary Expert Panel invites qualified experts to apply, and Governments and relevant organizations to nominate experts to participate in the second global assessment. 

The assessment will be conducted in line with the procedures for IPBES deliverables set out in decision IPBES-3/3, annex I and based on the scoping report for the assessment.

The assessment will be conducted by an interdisciplinary and transdisciplinary team of experts. The expert team will represent a diverse range of backgrounds, disciplines and knowledge systems, including Indigenous and local knowledge systems, and have regional and gender balance.

Eligibility

Experts should have experience in the conduct of regional and global analyses relating to nature and nature’s contributions to people in terrestrial, inland water, coastal and marine ecosystems. They should have expertise relevant to the global assessment of biodiversity and ecosystem services in one or more disciplines within natural science, social science or humanities. IPBES is, in particular, seeking experts with an interdisciplinary background. IPBES is also looking for experts on Indigenous and local knowledge, for policy experts and for practitioners in a field relevant to this global assessment.

All nominated experts need to be available to attend the relevant author meetings, with the first author meeting tentatively scheduled for end of November 2025.

Experts that are selected for a role within an IPBES assessment accept the relevant conditions for the assessment, including that the time contributed to IPBES is committed on a pro-bono basis. Experts from developing countries will receive support to attend author meetings and possibly other relevant meetings. Experts from developed countries are to secure their own funding to participate in the meetings.

Nomination process

Qualified experts who are interested in getting nominated by the ISC can get in touch with Anne-Sophie Stevance and Olivia Tighe at the ISC secretariat by 28 March.
