CALES is the heart and foundation of the University of Arizona's land-grant mission.

Founded in agriculture, rooted in life.

Uniquely positioned in the southern Arizona desert, we offer solutions to problems affecting much of the world and continue to build on our heritage of advancing the frontiers of science to improve the human condition. 

From the Earth's crust to outer space, our portfolio stretches from soil and plant science to natural resource and wildlife management, retailing and fashion to biotechnology and human wellness. Our research touches on nearly every aspect of modern life and has played a pivotal role in Arizona's and the global economy for more than a century. We empower our students with the skills they need to be the next change agents in their communities through 20 undergraduate degrees and 32 graduate programs.

"CALES has remained a standard-bearer for the Land-grant University ideal of education for everybody, not only a privileged minority. Generations of our faculty, researchers and students have played vital roles as leaders, innovators, and economic drivers not only in Arizona but all over the world."
