There’s a longstanding attitude in many farming communities that trees and agriculture don’t mix.
There’s a longstanding attitude in many farming communities that trees and agriculture don’t mix. But agroforestry — the intentional integration of trees and shrubs in agricultural systems, such as planting trees as windbreaks, integrating trees on pastures, or growing tree crops intercropped with annual crops — can provide a multitude of benefits to both farmers and landscapes. So far, in the U.S. Midwest, these benefits have gone unrealized, with vanishingly small adoption rates.
University of Illinois Urbana-Champaign researchers say strategic plans that integrate environmental, social, and economic considerations are needed to expand agroforestry throughout the Midwest. Their new study in Environmental Research Letters provides a foundation.
“There has been a lot of research on the agronomy and ecology side of agroforestry, including the environmental benefits these practices can offer. But we don't know a lot about the social and economic impacts. It turns out those factors dramatically shift our priorities for targeting agroforestry in certain areas,” said lead study author Sarah Castle, who completed the analysis during her doctoral studies in the Department of Natural Resources and Environmental Sciences (NRES), part of the College of Agricultural, Consumer and Environmental Sciences at Illinois. Castle is now a postdoc at Yale School of the Environment and a visiting scholar at Illinois.

A new University of Illinois Urbana-Champaign study integrates social, economic, and environmental factors in a new mapping tool that plots suitability for agroforestry practices, like the alley cropping system shown here, across the landscape. The researchers have made the decision support tool available for policymakers and land managers. (Photo Credit: University of Illinois Urbana-Champaign)
