Interpretive Summary:

Technical Abstract: Long-term research conducted at multiple scales is critical to assessing the effects of key long term drivers (e.g., global population growth; land-use change; increased competition for natural resources; climate variability and change) on our ability to sustain or enhance agricultural production to meet future global demand for agricultural products (e.g., food; feed; fiber; fuel).  To address this need, the US Department of Agriculture’s Agricultural Research Service (ARS), in collaboration with a broad group of partners, identified and reorganized existing long-term research infrastructure (i.e., benchmark watersheds; experimental ranges; research farms) into a Long-Term Agro-ecosystem Research (LTAR) network, the only long-term research network focused specifically on US agro-ecosystems.  In 2014, the initial network of 10 sites was expanded to 18 sites, including 3 sites led wholly or in part by non-USDA entities.  Later this year, the LTAR network will make the first near real-time data sets from all 18 sites available on the web.  This talk will focus briefly on LTAR establishment history, but primarily on LTAR’s current status and next steps, including plans for a final network expansion to complete coverage of key farm resource regions in the continental US.  In the broader context of this symposium, this talk will set the stage for discussions of complementary long-term research networks (e.g., LTER; NEON) and potential future collaborations to address questions of mutual interest.
