In the last few months leading up to the 2007 ADSA-PSA-AMPA-ASAS Joint Annual Meeting, considerable discussion has taken place in Washington, DC, concerning research funding. These discussions have direct implications for animal scientists working at federal, state, and corporate research and educational facilities. Topics have included: federal “earmarks,” authorization vs. appropriation bills, 2007 Farm Bill, 2007 and 2008 Budgets, National Institute of Food and Agriculture (NIFA), American Competitiveness Initiative (ACI), and other innovation proposals.

This plenary session will help you discover the impacts of the federal budget proposals on major R&D agencies, examine historical R&D trends and their impact on US science and engineering, and discuss the political outlook for R&D in the appropriations process.

Speakers include: Ashley Peterson, Congressional Science Fellow; Lowell Randel, USDA Deputy Assistant Secretary for Congressional Relations; and Kei Koizumi, Director R&D Budget and Policy Program Directorate for Science and Policy Programs at AAAS; and additional representatives from the executive and legislative branches of the US government as well as other specialists outside the federal agencies.
