The Sustainable Dairy Project is comprised of investigators from 8 academic institutions and 4 USDA Agricultural Research Labs, with strong support from dairy industry staff at the Innovation Center for US Dairy. Project team members work collaboratively across disciplines and institutions conducting targeted research, education, and extension in the area of climate change adaptation and mitigation efforts in dairy production systems of the Great Lakes region. Project leadership is based at the University of Wisconsin-Madison. The project team is pictured above during the 2014 team meeting held at Dairy Management Incorporated.
