Conservation Realities in Northern Mexico is a trans-disciplinary field course that will immerse students in the frontier of social and environmental research and conservation issues in the multicultural U.S.-Mexico borderlands. The University of Arizona has a distinguished history of offering cross-border field courses, which this course continues. Learning will be based in Tucson at the historic Desert Laboratory on Tumamoc Hill, and in the field in Northern Mexico in the remarkable islands of the Gulf of California and mountains and canyons of the Alamos region in southern Sonora. The course will leverage partnerships both across campus and with communities in Mexico to provide transformative learning opportunities for advanced undergraduate and graduate students. Specifically, the class follows a social and environmental curriculum that addresses on the ground conservation, focusing on two distinct geographic and cultural case studies. The first module will be based in the Midriff Islands of the Gulf of California in partnership with the indigenous Comcaac and Prescott College Kino Bay Center. The second will be based in the tropical dry forest and campesino communities of Alamos, Sonora region, partnering with the Reserva Monte Mojino, a project of Nature and Culture International.
