National Center for Appropriate Technology

The National Center for Appropriate Technology (NCAT) is an American organization headquartered in Butte, Montana, that is dedicated to appropriate technology and sustainability. Projects specifically deal with sustainable energy, sustainable agriculture and food, sustainable living, farm energy, and climate change. The center was created in 1976 by the merger of several energy conservation programs started after the 1973 oil crisis.

It carries out projects within the United States, especially in poor rural areas. It has regional offices in Davis, California; Fayetteville, Arkansas; San Antonio, Texas; Jackson, Mississippi; and Keene, New Hampshire.

Its headquarters is located in the former Silver Bow County Poor Farm Hospital, which is listed on the U.S. National Register of Historic Places.

ATTRA
Since the farm crisis in the 1980s, NCAT has operated ATTRA (attra.ncat.org), the National Sustainable Agriculture Information Service. The program goal is to provide technical assistance to farmers throughout the nation in succeeding with sustainable, organic and regenerative agriculture. The roughly two dozen specialists can assist farmers in everything from pest management and crop selection to farm business planning and marketing. Around 500 publications are available for download on the ATTRA website and the vast majority of them are free. They are based in the latest scientific research and are constantly updated. The website is also home to numerous tutorials, webinars and short videos.

ATTRA was originally an acronym for "Appropriate Technology Transfer for Rural Areas" which has since fallen out of use and is just "ATTRA".
