Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)

What is IPBES?

In 2012 the world’s governments agreed to establish the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) as a mechanism for strengthening the global science-policy interface for biodiversity and ecosystem services. Since then, IPBES has become the leading intergovernmental body for assessing the state of the planet's biodiversity, its ecosystems and the essential contributions they provide to society.

The most prominent aspects of the IPBES work programme are the assessments on themes such as pollination and land degradation and methods such as modelling and valuation. Following on from four regional assessments, the 2019 Global Assessment of Biodiversity and Ecosystem Services helps to inform better policies and actions in the coming decade, by providing the first global synthesis of the state of nature and ecosystems since the landmark Millennium Ecosystem Assessment was published in 2005. Not only does this work provide policymakers with objective scientific assessments and support the needs of other Multilateral Environmental Agreements (MEAs), JNCC uses the outputs provided by IPBES to inform its own evidence-based approach to providing advice on reducing pressures and impacts on biodiversity both in the UK and internationally.

JNCC provides support to Defra in representing the UK’s interests at the annual IPBES Plenary as well as at the extensive programme of stakeholder meetings and workshops supported by experts in the biodiversity and ecosystem service field. Defra and JNCC are also responsible for reviewing IPBES papers and assessments, and organising meetings to engage UK experts and stakeholders.

To date, 30 UK experts across the disciplines of natural science, economics and social research have contributed to the work programme of IPBES as: assessment co-chairs; co-ordinating lead authors; lead authors and review editors; and task force members. IPBES provides an excellent opportunity to showcase UK scientific excellence, and experts also gain further experience working at the science policy interface.

To support effective UK engagement with IPBES, JNCC has built the UK IPBES Stakeholder Network.Through this Network we provide communications on opportunities and outputs from IPBES.
