农林业的做法和政策影响的发展和通过在美国进行审查，农林业被定义为“密集的土地管理系统，优化的好处时，树木和/或灌木故意与作物和/或牲畜相结合的生物相互作用”。在美国，被确定为具有重要性的五种农林系统是树木-农艺作物系统（小巷种植和间作）、河岸植被缓冲带系统、树木-动物系统（造林）、森林/特种作物系统（森林耕作）和防风林系统（防护林）。美国没有专门针对农林业的联邦政策，如果要使农林业在美国充分发挥潜力，就必须为其发展提供充分的财政、体制和技术支持。
Agroforestry practices and the policies influencing development and adoption within the United States are reviewed, Agroforestry is defined as 'intensive land-management systems that optimize the benefits from biological interactions created when trees and/or shrubs are deliberately combined with crops and/or livestock'. The five agroforestry systems identified as having importance in the US are tree-agronomic crop systems (alley cropping and intercropping), riparian vegetative buffer strip systems, tree-animal systems (silvopasturing), forest/speciality crop systems (forest farming) and windbreak systems (shelterbelts). A lack of federal policy relating specifically to agroforestry exists, If agroforestry is to achieve its full potential in the United States, adequate financial, institutional and technical support for its development must be provided.
