About ONet

The Open-ended Network of IPBES Stakeholders (ONet) is recognised and underpinned by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). ONet is a space for stakeholders to organise among the community, engage with IPBES, and support the platform's work: in service of biodiversity and nature's contributions to people.

ONet was established following a decision by the third IPBES Plenary in 2015 (Decision IPBES-3/4), and encouraged by the stakeholder community. The network is part of the IPBES Stakeholder Engagement Strategy, a novel and in some ways unique approach among institutions like IPBES.


“An important element for the relevance, effectiveness, credibility and overall success of the Platform.”

What we do

  • ONet fosters communication between stakeholders and IPBES. We provide information on IPBES. We organise meetings between stakeholders and the IPBES Secretariat. We co-organise Stakeholder Day, our main conference, prior to each plenary session. We coordinate stakeholder statements at the plenaries.
  • We help disseminate IPBES products and achievements. For an example, see our resource page on the 2023 Invasive alien species assessment. We support capacity-building in service of biodiversity and nature's contributions to people. For an example, see our e-learning catalogues.
  • ONet strengthens support for IPBES. We engage with different groups and communities. We mobilise intangible and in-kind contributions to the platform.
  • We host an online space for the stakeholder community. Here you can find other stakeholders, share events, publish your news, stories and insights, and more: get involved today.

ONet membership

Membership of ONet is free of charge and comes at no financial cost. The IPBES plenary is keen to engage diverse stakeholders: it has emphasised diversity in geography, disciplines, and knowledge systems. For more detailed information on ONet, please see the terms of reference.
>> Key documents and resources

If you'd like to engage with IPBES on biodiversity and nature's contributions to people, you are a potential stakeholder: ONet welcomes both contributors to IPBES, as well as distributors and end-users of its products. Among stakeholders, we welcome policy makers and government officals at all levels, researchers of all disciplines, environment practitioners, people who hold local knowledge relevant to biodiversity, businesses and industry, community organisations, intergovernmental and non-governmental organizations, media, and communities and the public at large.

IPBES Stakeholder Registry & Networks

Alongside their participation in ONet, all members are also encouraged to join the IPBES Stakeholder Registry: you will receive official IPBES communications for stakeholders directly.
>> IPBES Stakeholder Registry

ONet is one of two IPBES stakeholder networks. The second is the International Indigenous Forum on Biodiversity and Ecosystem Services (IIFBES). All IPBES stakeholders are welcome to request to join either or both networks.

Within ONet, members with interests in the social sciences and humanities are invited to join a dedicated network:

The ONet facilitation team

The facilitation team look after ONet's virtual spaces and coordinate the network. The team's members meet at least once a month throughout the year. They respond to issues relating to the IPBES work program, plan events, such as speaker series, and undertake surveys to assess the needs and wishes of the stakeholder community.

Furthermore, the facilitation team organise ONet Caucus Days. They work with the IPBES Secretariat to plan and deliver the Stakeholder Day that precedes each IPBES plenary. The facilitation team also coordinate IPBES stakeholders' joint efforts in crafting their statements to IPBES plenaries.

Thomas represents the Social Sciences and Humanities Network (SSH Network) on the facilitation team: an ONet sub-group and member organisation working to improve the integration of SSH knowledge within IPBES.

Thomas E. Sutcliffe, PhD is a social scientist and researcher at the Norwegian Institute for Nature Research (NINA) where he uses qualitative methodologies to investigate aspects of governance, knowledge, and societal transformations that are intertwined with issues of area use, land-use changes, ecosystem restoration, and biodiversity. Moreover, he is pursuing interests in understanding how society represents and understands forms of crises related to nature and biodiversity, but also to issues of justice and pollution. Thomas holds a PhD in Interdisciplinary Studies of Culture where he researched the concept of the circular economy and how, in particular, sub-national authorities govern this concept and how the politics of consumption plays into the implementation of the circular economy.
