Transforming Agriculture, Perennially



Tim Crews

Director of Research and Lead Scientist, Ecology Program

Tim, director of research, is at the Land Institute because in his words, “the work is the most focused and far reaching of any organization I know. It promises to transform agriculture from being an ecological liability to an asset.” Tim first visited The Land Institute in 1981 after reading New Roots for Agriculture as an undergraduate majoring in agroecology at University of California-Santa Cruz. Over the next three decades he pursued a doctorate degree at Cornell, carried out a post-doc fellowship at Stanford and developed an agroecology program at Prescott College in Northern Arizona. But all along he continued to track the work of The Land Institute, and in 2000 began to collaborate directly. In 2012 Tim joined the staff as director of research and an ecologist. He helps facilitate and coordinate research efforts of his colleagues, and conducts work on the ecosystem functions performed by soils.
