The grasslands, rangelands and savannas of the world lock up carbon. Overgraze them and we create desertification and release carbon. By grazing animals in a holistic, planned way: Mimicking nature and replicating how herds of wild animals graze, moving on in tight formation once the pasture is manured, we can regenerate grasslands, prevent soil erosion and ensure the health of the animals. With this system, animals are not forced to overgraze on land covered in their faeces. Alan Savoury's work is pioneering and many people are now successfully trying out these practises all over the world. This is a vital aspect of developing not only a sustainable agriculture but one that can regenerate landscapes and ecosystems.
