Many faculty and students in the Department of Community Sustainability conduct research related to international development, often applying the ideas associated with the other thematic areas to developing country contexts. Additional departmental work in international development addresses agricultural technology adoption, nutrition-agriculture linkages, and collective action to manage commonly held natural resources. Participatory, action, and mixed methods research approaches are used extensively.<br>The Doctor of Philosophy in Community Sustainability is designed to enable students to generate new knowledge in complementary fields responsive to rapidly changing conditions in our natural environment and agricultural systems. The CSUS graduate program is designed for students interested in issues of community sustainability in either a domestic or international context. Broadly speaking, faculty, academic staff, and graduate students working in this graduate program tend to focus their work on community food and agricultural systems, natural resources and the environment, tourism and recreation systems, education and civic engagement, and international development. These themes are very broad and they overlap not only with each other but also with issues around sustainable tourism and protected area management, the focus of the department's other MS and PhD graduate programs. We apply our work in these areas in both domestic and international settings, with numerous faculty and graduate students working in the context of international development.
