Welcome to the Intercultural Center for the Study of Deserts and Oceans.

Join us to explore, understand, and protect the natural resources and cultures of the Sonoran Desert and Sea of Cortez. Our mission is to bring together people, knowledge and solutions for vibrant communities AND resilient ecosystems, in the northern Gulf of California and beyond.

By promoting environmental awareness, disseminating knowledge and encouraging civic participation, CEDO is a fundamental force driving civic dialogue and transparent decision-making. CEDO has been the promoter of a vision:  the vision of an open, participatory society  consciously building its own future.
