New approach for protecting and restoring nature
All over the world, people depend on nature for their wellbeing, in the form of food, clean water, flood protection and other benefits. So, in a rapidly changing world, one of the main challenges for humanity relates to protecting and restoring nature.
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) provides policy makers with scientific assessments about the state of knowledge regarding the planet's biodiversity, ecosystems and their contributions to people. Nominated by the Dutch government and the IPBES secretariat, van Oudenhoven is involved in IPBES as one of the youngest lead authors, phys.org wrote.
Together with thirty global experts associated with IPBES, and led by Professor Sandra Díaz and Professor Unai Pascual, Alexander van Oudenhoven has published an open access policy forum paper today in the journal Science. The authors write about an innovative new approach: Using different perspectives on and a wider range of nature's contributions to people to inform policies and decisions.
Nature and culture
In an official press release by IPBES, Sandra Díaz explains: "The notion of nature's contributions to people emphasizes that culture is central to all of the links between people and nature, and recognizes other knowledge systems, for example those of local communities and indigenous peoples, much more than before."
Van Oudenhoven has been involved in discussions on the IPBES approach since 2015, when he and his fellow authors started the regional assessment of biodiversity and ecosystem services in Europe and Central Asia. What excites him the most about the paper is the call to look beyond Western science as a way to collect information.
"If the notion of nature's contribution to people is to appeal to decision makers worldwide, then we need to understand how different cultures experience nature," he said.
"Nature shapes peoples' identities, contributes to physical and mental health, inspires art and design. The social, cultural, spiritual and often religious significance of nature needs to be acknowledged and valued, in addition to the "Western' notion that nature provides goods and services. That is exactly what our approach enables."
One of the many concrete applications of this new approach is its uptake in large-scale expert assessments and how these are conducted. The IPBES regional assessments of Europe and Central Asia, coauthored by van Oudenhoven, are expected to be released in March this year, together with three other IPBES regional assessments. These assessments have already included unprecedented efforts to tap indigenous and local knowledge. In addition, nature's contributions to people are already a central feature of the IPBES global assessment, expected in 2019.
