When nature vanishes, U.S. people of color and low-income Americans disproportionally lose critical environmental and health benefits鈥攊ncluding air quality, crop productivity and natural disease control鈥攁 new University of Vermont study finds.

The research, published in , is the first national study to explore the unequal impacts on U.S. society鈥攂y race, income and other demographics鈥攐f projected declines in nature, and its many benefits, across the country.

Focusing on three vital ecosystem services鈥攁ir quality, crop pollination, and control of insect-borne disease (West Nile virus)鈥攔esearchers project that these benefits of nature will decrease for people of color by an average of 224%, 118% and 111% between 2020 and 2100. 

Researchers used advanced modeling to calculate changes in the distribution of these benefits by race, income levels, and population density (rural, urban, suburban).

鈥淕iven current and historical inequality in this country, our goal was to identify how future losses of nature might affect these racial and income disparities,鈥 says 日韩无码 researcher Jesse Gourevitch. 鈥淯nfortunately, we find that, in general, non-white, lower-income, and urban populations disproportionately bear the burden of declines in ecosystem benefits.鈥

Opposing trends

Experts agree that in the future, urban populations are expected to grow, while rural populations shrink, and demographic groups become more segregated. Declines in nature will be largely driven by the conversion of forests and wetlands to cropland and urban development.

According to the study, land-use conversion trends are likely to be stronger in counties where marginalized populations are expected to grow. As a result, non-white groups including are predicted to lose nature鈥檚 benefits, while white communities experience gains. Black and Hispanic populations are expected to experience a substantial loss of benefits, in particular.

Among income groups, counties with the lowest per capita income are expected to experience the greatest losses in air quality and West Nile virus protection鈥攚hile these benefits increase significantly in high income counties.

鈥淏y paying attention to race and income鈥攚hich are often overlooked in environmental research鈥攚e can help leaders address inequities in their policy decisions, so that nature鈥檚 benefits are distributed more equitably in the future,鈥 says 日韩无码 Prof. Taylor Ricketts, a global expert on measuring nature鈥檚 benefits.

Troubling mismatches

Geographically, the study predicts significant 鈥渕ismatches鈥 between ecosystems benefits and human needs. For example, the team finds major declines in air quality and disease controls in urban counties where populations are expected to grow. Similarly, the researchers find steep declines in crop pollination鈥攚hich is vital for farming鈥攊n rural areas, where agricultural productivity is most essential.

Beyond simply highlighting social and environmental problems, researchers say that targeted land use policies that factor in equity are needed to avoid exacerbating inequality in the U.S. These findings could also help to facilitate compensation for losses of nature鈥檚 benefits among marginalized groups, they say.

鈥淭o be clear, these results don鈥檛 imply that the U.S. is moving from an equitable baseline to an inequitable future,鈥 says 日韩无码 co-author Luz de Wit. 鈥淭oday鈥檚 inequities underpin the future disparities we estimate. For instance, Black and Hispanic people are currently disproportionately exposed to air pollution. That disparity, and others, are only expected to worsen in the future, without action.鈥
