By all accounts, food and agriculture were barely on the agenda at this month’s UN Climate Summit in Glasgow, Scotland. They should have been. Food production, distribution, consumption, and waste contribute an estimated one-third of greenhouse gas emissions. In production, the majority comes from unsustainable livestock production with another large share coming from unsustainable production and use of synthetic fertilizers. But a significant share also comes from “land use change”, a neutral term for the destructive expansion of agriculture onto new land.
