As an example, experts point out that climate change is forcing some migratory fish species to change their route to the poles, which means a big change for people whose livelihoods depend on fish. "What we found is that natural resources such as fish are being pushed by climate change, and who has access to them is changing," said one of the authors of the work, Malin Pinsky.
Thus, he has indicated that, the stronger the conservation oriented to the management of natural resources in a community, the greater the value of said natural resources and if these resources increase or decrease. Thus, if richer countries and communities are more likely to have strong resource management, these groups are more likely to benefit, exacerbating inequality.
Wealth is shifting
Pinsky and his co-authors have explained that "inclusive wealth" - in fish, plants and trees and other species important to humans - is moving out of temperate zones and toward the poles as global temperatures rise. Inclusive wealth is the sum of a community's capital assets, including natural assets like fish or trees, but also human health and education, as well as built assets like roads, buildings, and factories. As the climate changes unevenly from place to place, natural resources migrate - or reproduce - unevenly.
Their work, published in Nature Climate Change, uses data that Pinsky developed in his studies on fish migration and a mathematical formula developed by Yale University economist Eli Fenichel, to illustrate the relationship between the movement of resources and the movement of the wealth.
To illustrate their point, the authors set up a model with two fictitious communities, Northport and Southport, each dependent to some extent on a particular fishery. The authors then imagined scenarios of interaction between the two communities, the action of their fish, and each other.
"We tend to think of climate change only as a problem of physics and biology. But people react as well and, at the moment, we do not have a good understanding of the impacts of human behavior on the natural resources affected by the change. climate ", has pointed out the scientist.
One of the upcoming projects for the team will lean towards the human side of the equation. The experts will spend part of the spring and summer talking to people involved in commercial fishing across much of the East Coast of the United States.
