H51Q:
Development of the Long-Term Agro-Eecosystem Research Network I


Session ID#: 10631

Session Description:
USDA/ARS is reorganizing 18 existing benchmark watersheds, experimental ranges, and research farms into a continental-scale Long-Term Agro-ecosystem Research (LTAR) network, including 3 led by land grant universities and/or private foundations.  The central question to be addressed by the LTAR network is How do we sustain or enhance productivity, profitability, and ecosystem services in agro-ecosystems and agricultural landscapes? However as LTAR moves forward, the focus is on defining and collecting a core set of common measurements over the next 30-50 years so that they can be used to evaluate changes in agricultural sustainability across regional and continental-scales.  This session will solicit presentations that illustrate 1) the design and utility of LTAR as a network, 2) progress at LTAR locations, 3) LTAR network-level research and cross-site experiments, and 4) coordination between LTAR and other research networks (Ameriflux, CZO, Fluxnet, LTER, NEON, etc.).
