In December 2020, France and the world were in the middle of the COVID pandemic: all people are on the TV channels talking about the virus. Yet at the same time, the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) published the first ever report on the state of biodiversity and its relationship to climate change.

Summary for Policymakers

The sixth mass extinction (also call Earth's Loss of Biodiversity): no one talks about it and yet it is the cornerstone of an edifice that is collapsing. We could call IPBES as the "IPCC of biodiversity". The aim of its report, like the IPCC ARs (Assessment Reports), is to take stock of the ecosystem’s health by publishing a meta-analysis of all the knowledge and actions implemented since the "Aichi Targets" in 2010. This new report was co-authored by 150 experts (from 50 countries) and took 3 years to write. It synthesises nearly 15,000 scientific publications.

Of the 20 targets set by the Convention on Biological Diversity in October 2010 ("Aichi Targets"), none has been "fully met" in 2020 and only 6 targets are rated as "partially met".

Summary for Policymakers

The constant isn’t disappointing, it’s catastrophic! The main issue that the IPBES report highlights is the need to "immediately" redefine the way we live in space: indeed, the main cause of the destruction of ecosystems and the disappearance of animal and plant species is the loss of habitat. Humans are taking up more and more space on the planet, particularly due to livestock farming, agriculture, deforestation and urban expansion (which are the main factors highlighted by this report).
