Changing the tools used to assess food systems is an immediate way to take action that promotes human, animal, and planetary health. Simplistic economic productivity metrics like ‘yield-per-hectare’ mean that negative externalities — habitat destruction, soil erosion, water contamination, displacement of Indigenous Peoples, diabetes, and more — go unaccounted for in the final price of food, in policy documents, and on balance sheets (but the price is still paid). This also means that positive impacts — carbon sequestration, insect pollination, resilience to natural disasters, and vibrant communities — are hidden and can’t be enhanced.
I am often asked by people interested in true cost accounting: ‘where do I start?’ I now have the answer. Authored by some of the great thought-leaders in food and agricultural systems, these new materials are a user-friendly and accessible resource for the community.

The TEEBAgriFood Framework (“The Economics of Ecosystems and Biodiversity”) is already being used by policymakers, investors, and farmers around the world to comprehensively evaluate their work, fill in the gaps, and make better decisions about the future. For example, a CONABIO valuation of maize production systems found that the lack of genetic diversity in corn grown in the USA and Canada — which makes them more vulnerable to pests and disease — resulted in yield losses of $27,403,616,604 between 2012-2015. Genetically diverse crop species are more resistant and not subject to the same type of losses.
