The least productive 10-20% of producers are causing 60-80% of the environmental impacts but only produce 5% of the food. Incentivizing these farmers and ranchers to change can significantly improve the sustainability of our food systems with minimum impact on global food production.

Today I am joined by Jason Clay from WWF who focuses on working with the private sector to improve supply chain management especially addressing habitat, biodiversity, soil health, irrigation, effluent, and green house gases. Jason leads the Markets Institute to improve sustainability in internationally traded food and soft commodities, known as Codex Planetarius.

We need to move away from looking at averages. With the largest 10 commodites we are finding there are three to five production systems globally and the difference between the most damaging decile and most sustainable decile is 10x. Between any two of the 5 production systems it can be 50 or 100x. Huge reduction in the environmental footprint of these systems can be achieved by addressing the bottom.
