Assessing nature's contributions to people

Plentiful food, clean water and healthy air are among the most valuable and visible benefits of nature to people. This has reinforced the widespread, and increasingly controversial, belief that nature is mainly a source of services or commodities.

Writing today in the prestigious journal Science , thirty global experts associated with the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), and led by Ikerbasque Research Professor Unai Pascual (BC3) and Professor Sandra Diaz  have presented an innovative new approach: the idea of using all of nature's contributions to people to inform policies and decisions.

"For more than a decade, policies about nature have been dominated by knowledge from the natural sciences and economics," said Sandra Diaz. "The vibrant research developed from this 'ecosystem services' approach - popularized by the landmark 2005 Millennium Ecosystem Assessment - has advanced sustainability, but largely excluded insights and tools from the social sciences, humanities and other key worldviews. The much broader 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."

Sir Robert Watson, IPBES Chair and former co-chair of the Millennium Ecosystem Assessment, said: "Nature's contributions to people are of critical importance to rich and poor in developed and developing countries alike. Nature underpins every person's wellbeing and ambitions - from health and happiness to prosperity and security. People need to better understand the full value of nature to ensure its protection and sustainable use."

"This new inclusive framework demonstrates that while nature provides a bounty of essential goods and services, such as food, flood protection and many more, it also has rich social, cultural, spiritual and religious significance - which needs to be valued in policymaking as well."

"Food is a great example," said Unai Pascual, "We all receive food from nature and food security is a key aspect that has typically been included in policies and decisions around the world, often measured in the context of calories per day, biological processes and economic value, for example. But we know that food is so much more. It's at the center of cultural identities, art and basic human enjoyment. It is these kinds of non-material contributions from nature that the new approach seeks to represent and include in decisions about the way we relate with nature."

One of the many concrete applications of this new approach is its uptake in large-scale expert assessments and how these are conducted. Professors Diaz and Pascual concur that nature's contributions to people is a scientific advancement embracing, but going beyond the ecosystem services approach, which will increase the effectiveness and legitimacy of policies and decisions about nature. "This inclusiveness and equity among knowledge systems and perspectives will not only make assessment processes more legitimate; it will also lead to better policy results because we will be drawing from a much richer and wider information base".

Four IPBES regional assessments of biodiversity and ecosystem services, expected to be released in March this year, have been included unprecedented efforts to tap indigenous and local knowledge, and nature's contributions to people are already a central feature of the IPBES global assessment, expected in 2019.
