Report of the Plenary of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services on the work of its seventh session
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has released its first global assessment of biodiversity, its contributions to humanity and scenarios for its conservation. This report has left us with big headlines in the media and has put biodiversity in the center of the public agenda. However, far from the big headlines of the moment, the science community have been rising the alarms since long time ago. The report covers the decline in biodiversity and ecosystem services, the drivers of this change, the failure to meet many conservation goals and the transformative change needed to rise to the challenge. IPBES report has generated a lot of headlines but, what else is on it?
The most shocking headline that IPBES report has left is that 1
million species are at risk of extinction. This number comes from
the knowledge of experts that have calculated that 25% of the species
evaluated in the IUCN Red List are at risk of extinction. However is
also important to continue the sentence, the report also said that
this risk is imminent, many of these species face extinction in the
next 10 years, if we don’t do something about it. Moreover,
without action, the rates of biodiversity loss will incense 10 to 100
times the background levels.
Another conclusion that is clear from this report is that the causes
of the decline on biodiversity are human activities. Changes in land
and sea use, direct exploitation of organisms, climate change,
pollution, and invasion of alien species, are the main drivers that
are threatening biodiversity. At the same time, these threads are
also threatening humans well being. Biodiversity and healthy
ecosystem are vital contributions for human existent. This
contribution takes a lot of forms form ecosystem goods and services
to naturals gifts.
The most encouraging part of the report is that we still have time to
reverse these dramatic trends, but we have to start working right
now, it is an urgent matter. We have to put biodiversity at the top
of the global agenda. This will require changes in western economic
and social systems and changes in our patterns of production and
consumption. It will require the sustainable production of food and
other resources, alongside a reduction in greenhouse gas emissions.
Society needs to shift from an economic growth perspective to a
nature-based one. The report also confirms that nature managed by
indigenous people and local communities are in better health than
other managements systems. Therefore, to conserve natural ecosytems,
governments need to learn from these communities, implementing their
knowledge of nature into future policies.
This report is based on 15,000 scientific articles and government
reports, integrating information from natural and social sciences,
indigenous peoples and traditional agricultural communities. From the
Global Mammal Assessment, we contribute to scientific biodiversity
knowledge. As members of the IUCN Red List Partnership we are
dedicated to the assessment of mammal extinction risk. Moreover we
work in the development of species distribution models, the forecast
of scenarios of future native and introduced species, risk of
extinction due to climate change, and SDGs. Carlo Rondinini,
coordinator of the Global Mammal Assessment, was one of the experts
invited to write the IPBES report.
