About Agroforestry

Agroforestry intentionally combines agriculture and forestry to create integrated and sustainable land-use systems. Agroforestry takes advantage of the interactive benefits from combining trees and shrubs with crops and/or livestock. Agroforestry practices include:

About the NAC

The USDA National Agroforestry Center (NAC) had its origins in the 1990 Farm Bill. It began as a Forest Service Research and State & Private Forestry effort in 1992 and expanded into a partnership with the Natural Resources Conservation Service (NRCS) in 1995. It is administered by the Forest Service's, Washington, DC, Office of Research and Development. NAC offices are located in Lincoln, Nebraska and Blacksburg, Virginia.

NAC accelerates the application of agroforestry through a national network of partners. Together, we conduct research, develop technologies and tools, coordinate demonstrations and training, and provide useful information to natural resource professionals.

About Working Trees

The right trees planted in the right places for the right reasons can add value to land-use systems. That's the Working Trees message that helps natural resource professionals, community leaders, and landowners identify with the concept of agroforestry. NAC uses the Working Trees theme to promote the development of sustainable agriculture and communities.
