Rethinking Food Systems World Environment Day, the United Nations Environment Programme (UNEP) and partners launched the * Transformative Partnership Platform*on agroecology - a **farming approach that’s inspired by natural ecosystems combines local and scientific knowledge and focuses on the interactions between plants, animals, humans and the environment. As the UN prepares for its first-ever Food Systems Summit in September 2021, we explore the impact of food systems on the environment.* Over decades, as populations have grown, more people are consuming - and wasting more food – than ever before. Unsustainable food production and consumption patterns are a common thread, running through many of the greatest challenges facing humanity today.
