The Intercultural Center for the Study of Deserts and Oceans, Inc., CEDO, is a binational not for profit 501 (c) 3 environmental organization whose mission is to foster vibrant communities and resilient ecosystems in the Northern Gulf of California and other ecoregions by integrating people, knowledge and solutions. For 40 years CEDO has tested and developed six essential building blocks focused on strengthening communities to participate in the design and realization of sustainable livelihoods to ensure their future and the health of the ecosystems on which they depend. The blocks are integrated to achieve ecosystem conservation and fisheries co-management in two eco-regions of the Northern Gulf of California: The Upper Gulf of California/Colorado River Delta Biosphere Reserve and the Puerto Peñasco- Puerto Lobos Biological Corridor. CEDO develops environmental education programs focused on fostering an environmental culture and developing capacity and opportunities for collective action in support of sound management and sustainable livelihoods. Research and monitoring programs engage local communities in generating data that combines with scientific data to inform management and measure effectiveness of actions. Management focuses on developing sustainable fisheries, conservation of endangered species and maintenance of ecosystem services, and assessing and mitigating the impacts of climate change. Finally we promote economic solutions with market incentives that support responsible ecosystem management, promoting business models for ecotourism and sustainable fisheries that give added value for products caught responsibly.
