In a latest mission undertaken for the Colombian authorities, as an illustration, the Natural Capital Project assisted in establishing a conservation plan for the Caribbean Gulf of Morrosquillo and its hinterlands. The area’s Rio Sinú is a vital supply of ingesting water for a lot of downstream communities but in addition originates in an space that relies upon upon logging, ranching, and agriculture for its monetary safety. Using InVEST, Daily and her group have been in a position to decide the precise value of silt deposition within the river, notably for ingesting water and hydropower, and the worth of sustaining upstream forests that will forestall that congestion from occurring.
“We were able to show that communities in the region were benefiting from this forest in ways they hadn’t necessarily realized,” says Lisa Mandle, lead scientist and director of science-software integration for the Natural Capital Project. “We can never capture the total value of a forest in terms of cultural and spiritual values or even biodiversity, but we can say that it has measurable economic values across dimensions that have not been considered before.”
And that, says Mandle, has created highly effective incentives for the Colombian authorities to consider find out how to help the communities inside that essential forest.
An identical strategy, additionally crafted by the Natural Capital Project, helps international locations decide their gross ecosystem product, or GEP. Modeled after the gross home product, the GEP index permits nations to find out the financial worth of their ecological techniques. Daily and her group piloted this index in 2014 on each municipal and nationwide scales in China, and it was adopted by the United Nations Statistical Commission in 2021.
“Just as the Great Depression exposed the urgent need for better macroeconomic performance metrics, our current ‘Great Degradation’ of natural capital is making it imperative that we track ecological performance and use that information to guide investments in revitalization and regeneration,” says Daily, who predicts that the GEP metric will probably be employed globally throughout the subsequent decade.
In the meantime, she and her group are devoted to streamlining their ecological assessments in a approach that makes the ultimate evaluation and visualization simpler for political leaders, traders, and native communities to make use of. Making that info extra accessible, she says, will probably be essential for fostering a cultural shift towards recognizing humanity’s dependence upon the biosphere.
In some ways, this concept of codifying the worth of nature has been 30 years within the making. And it couldn’t have turn into actuality with out Daily’s imaginative and prescient, says Qingfeng Zhang, a senior director on the Asian Development Bank, which now features a Natural Capital Lab impressed and supported by the Stanford mission. This initiative, which was launched in 2020, created a platform for the financial institution to advertise sustainable finance with the assistance of instruments that Daily and her group developed.
“Gretchen’s work in the area of environmental science and its implications for public policy has been monumental,” says Zhang. “Her InVEST model and GEP concept are transforming the way governments, corporations, and civil society look at nature. We now have a tangible economic basis to invest in protecting and growing nature.”
