The interactive map was designed to illustrate the vulnerability of the world to changes in access to food provided by the global food system, such as natural disasters or political embargoes. Data from the Food and Agriculture Organization (FAO) of the United Nations has been used to show trade between countries. The map represents an interactive version of the FAO data, providing the ability to visualise the most significant impacts of removing one country from the global food system. The thickness of trade routes represent the quantity of trade flow,This site was designed and created by 6 students of the Masters in GIS programme in New Zealand, as part of a project for a course.
