Agriculture is being scrutinized for its potential to contribute to Homeland Security goals regarding food and energy production as well as for those being demanded by society, such as GHG mitigation, water quality protection and biodiversity enhancement.  By tradition, activities (i.e., discussions, research, monitoring and policy development) dealing with these issues get separated into land-use (e.g., agriculture, forests) and resource (e.g., water, wildlife, agronomy) buckets; a separation further reinforced by the institutional agencies involved.  The dominant GHG mitigation activities, for instance carbon sequestering options, generally reflect the more conventional core of each land-use discipline.  This single-issue/land-use approach dominating this and other natural resource programs has created competition between sectors rather than capitalizing on the synergies that can be derived by integrating across issues, sectors and land uses. Agroforestry, the integration of woody plants and food production systems, can serve as a significant carbon sequestering option on agricultural lands.  Agroforestry can simultaneously provide a flexible biomass feedstock production source, economic diversification and soil, water and habitat conservation; serving to ecologically connect the larger landscape while still leaving the bulk of the land in agricultural production.  Such mixed, diversified systems, however, go contrary to the direction agriculture has taken in recent decades, and it is not surprising that this option that straddles forestry and agriculture does not have much advocacy or investment from agronomic or forestry sectors.  Information is presented demonstrating the advantages of these systems in terms of carbon sequestration, water quality benefits, and biomass feedstock production, and their versatility for providing additional economic and environmental services.  An overview of tools to facilitate strategic placement, design, and landowner/stakeholder buy-in of agroforestry practices will be given.  We argue for more explicit inclusion and support of new crop production systems, like agroforestry, in greenhouse gas mitigation and other natural resource conservation strategies.
