American Geophysical Union 2015 Fall Meeting

American Geophysical Union Fall Meeting (14th- 18th December, 2015)

Session ID#: 8800

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.).

 Primary Convener:  Mark S Seyfried, US Dept Agr ARS, Boise, ID, United States
Conveners:  David C Goodrich, Agricultural Research Service Tucson, Tucson, AZ, United States and Mark R Walbridge, USDA ARS, Pendleton, OR, United States
