This course is an introduction to the ecosystem approach to health and well-being (ecohealth); an applied approach based on principles of systems thinking, transdisciplinarity, participation, gender and social equity, knowledge-to-action, and sustainability. The course will be a 10-day intensive course at York University’s Eco Campus in Costa Rica. In order to provide participants with a more concrete experience of ecosystem approaches to health, the course has been designed around the themes of EcoHealth and Watersheds and EcoHealth and Food. Both of these will focus on the case study of “linking health, environment and community” in the Alexander Skutch Biological Corridor.
