In the current times, characterized by innumerable social-environmental crises, it is necessary to explore initiatives that contribute elements to possible solutions. Costa Rica has been considered an international beacon of “Sustainable Development,” partly because of a number of arguably successful social and environmental initiatives. In this course we will engage directly with a diversity of initiatives in Costa Rica at different scales (State, Indigenous Territory, Rural Community, Family Farm, Co-operative, NGO, Grassroots Organization, Local Business, among others) that attempt to bring together elements of environmental conservation and social-economic development in order to achieve improved wellbeing and sustainability. These cases will provide material for discussion and analysis through diverse epistemological lenses, to provide students with a more informed, critical and inspired theoretical approach and praxis to urgent social-environmental issues.
