ISC nominees selected for new IPBES Assessments

Work begins on the new IPBES ‘Nexus’ and ‘Transformative Change’ Assessments, with co-chairs announced and leading international experts selected to contribute as authors. The International Science Council is pleased to announce that three of its nominees have been selected as lead-authors for the assessments.

ISC nominees selected for new IPBES Assessments

In July 2021, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) called for nominations of experts to participate in the assessment of the interlinkages among biodiversity, water, food and health (the ‘Nexus Assessment’), and the assessment of the underlying causes of biodiversity loss, the determinants of transformative change, and options for achieving the 2050 vision for biodiversity (the ‘Transformative Change Assessment’).

The International Science Council, which is uniquely positioned as a convenor of the scientific community and an advocate for transformations to sustainability, responded to this call by nominating experts from around the globe. Today, we are pleased to announce that three of our nominees were selected as lead-authors for these assessments:

Now that their scoping stage is completed, both assessments are currently under expert evaluation, where working groups will review existing literature and conduct expert meetings to synthesize available evidence. This month, the authors for the Assessments will have an introductory meeting. The Assessments will then be peer-reviewed (internally and externally) before their summaries for policymakers are negotiated by governments and relevant stakeholders and finalized and approved in the IPBES Plenary.

“These new IPBES assessments will be among the most complex and interdisciplinary ever undertaken.”

Dr. Anne Larigauderie, Executive Secretary of IPBES

Over the next three years, the undertaking of the Nexus Assessment will include the examination of the interlinkages among the sustainable development goals related to food and water security, health for all, protecting biodiversity on land and in the oceans and combating climate change.

“Since the publication of the IPBES Global Assessment, in 2019, Governments and other decision-makers have increasingly realized the importance of addressing the loss of biodiversity and the degradation of nature’s contributions to people holistically and with great urgency. The Nexus Assessment will help inform consideration of synergies and trade-offs in terms of social, economic and environmental impacts.”

Profs. Harrison, McElwee and Dr. Obura, co-chairs for the Nexus Assessment

The Transformative Change Assessment aims to understand and identify factors in human society at both the individual and collective levels, including behavioural, social, cultural, economic, institutional, technical and technological dimensions, that may be leveraged to bring about transformative change for the conservation, restoration and wise use of biodiversity, while taking into account broader social and economic goals in the context of sustainable development.

“The Transformative Change Assessment will offer practical options for concrete action to foster, accelerate and maintain the transformative change necessary for a more sustainable future.”

Profs. Agrawal, Garibaldi and O’Brien, co-chairs for the Transformative Change Assessment

As the world still recovers from the COVID-19 pandemic, and with less than a decade to reach the goals of Agenda 2030, the next few years are of paramount importance to increase the efforts to support societies in transforming towards a more equitable, more sustainable future.
