The University of Edinburgh is offering an online course via edX on sustainable global food systems. The course will examine food security from a food systems perspective and illustrate the major global challenges present, from the environmental impact of food production to the public health impacts of current and future diets. Topics include: where food systems and non-food policies interact, data collection tools and information on food system interventions.
The time commitment is estimated to be 3-5 hours per week for a total length of 5 weeks, although the course can be followed at your own pace on your own time. Enrollment is free, but a verified certificate can be added for €40.
