Sustainable Agriculture


Over the past two decades, our research has focused on agricultural and other land use issues, primarily in the Yaqui Basin, Sonora, Mexico. With our collaborators, including hydrologists, geographers, economists and agronomists, we have carried out interdisciplinary studies of intensive agricultural fertilization, water use, aquaculture development, and other land use changes in the tightly linked land-coast-sea system. Our goals are to understand the processes that control such land use decisions and their consequences, and to develop tools and approaches that allow managers to make sustainable choices in development and resource use across the entire Valley. 
While the Yaqui Valley research is no longer the focus of our work, we continue to be interested in working with others here at Stanford on sustainable agriculture and food security:
