National Agroforestry Center

The Center accelerates the adoption of agroforestry by leading, catalyzing, coordinating, and conducting research and science-based outreach. It is the only U.S. Department of Agriculture unit dedicated to agroforestry and is uniquely poised to provide U.S. leadership in agroforestry research and application. The staff has developed a seamless approach to conducting and integrating research and technology transfer within the Center. 

The research staff conducts, synthesizes, distills research, and produces tools and information that support land management decision-making. The technology transfer and applications staff develop and delivers science-based agroforestry information to natural resource professionals working with farmers, ranchers, forest landowners, Tribes, and communities. This information is delivered through publications, workshops, training, and demonstration sites. The Center relies on an extensive network of partners spanning a vast array of universities, non-profit organizations, state and Federal agencies, and conservation districts. These partnerships and networks continue to expand and serve a central role in the advancement of agroforestry research and technology transfer.

Background Information and History

The USDA National Agroforestry Center has 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 in 1995. It is administered by the Forest Service's Washington, DC Office of Research and Development. The Center's offices are located in Lincoln, Nebraska. Over the years, NAC has delivered more than 1.3 million requested publications into the hands of natural resource professionals who use them to promote agroforestry at workshops, trainings, and other events across the country. Our research program has evolved much over the past 25 years — from developing stress and pest resistant plant materials for the Great Plains to providing management solutions that address a wide range of forest and agricultural needs across the United States. The Center has had many impacts in the field of agroforestry through its tool development, outreach, education, and partnerships across the country.

Agroforestry is the intentional combination of agriculture and forestry to create productive and sustainable land use practices. These practices take advantage of the interactive benefits from growing trees and shrubs together with crops and/or livestock. Agroforestry has its roots in tropical food production systems. In regions with more temperate climates, agroforestry is separated into five distinct but related practices. The five practices are windbreaks, riparian forest buffers, alley cropping, silvopasture and forest farming.

Topics

Agroforestry working groups, communities, and networks have a long history. These regional working groups have helped to amplify awareness and establishment of agroforestry systems by providing regional expertise and linkages for agroforestry education, outreach, research, and policy. Participants also vary from group to group, with some groups including producers and practitioners, others focused on researchers, some involving technical assistance providers, and, most often, a collaboration of all of these participants. 

Here is a list of some of the existing agroforestry working groups in the US. Please contact the USDA National Agroforestry Center if you are involved with another working group that you would like added to the list or you want more information about any of these groups.
