TEEBAgriFood, part of the UN Environment initiative The Economics of Ecosystems and Biodiversity, has released a report on the environmental, health and social costs and benefits of the agriculture and food system. It finds that the food system does not keep everyone healthy or protect the environment. It calls for a reform in how we measure food system performance, because relying on yield per hectare and market prices neglects other costs such as food-borne disease and environmental degradation.
The report can be downloaded here as a work in progress. An 84-page synthesis report is also available here (PDF link). A shorter summary can be found in the press release here (PDF link). See also the Foodsource resource How do food systems affect land-use and biodiversity?
