1 Dr. Allan Savory Holistic Management Abe Collins Carbon Farmers of America Joel Salatin Mob grazing & Chicken tractor Greg Judy Grass-fed beef Gary Zimmer Biological Agriculture Crops plant successions & services biodiversity & polycultures plant & insect communities : land improvement by grazing Livestock Soil Carbon Coalition long-term, rapid rotations of crops & livestock Rotations Climate Change Confronting To advance the practice put the carbon back where it belongs to turn atmospheric carbon into soil organic matter and engage people in opportunities Grass-fed beef is better for people and land. Feeding cattle grass throughout their life is the most sustainable way to raise beef. weed & pest control home-grown fertility UK National Trust This is contrary to belief livestock farming must intensify to feed increasing population. Debate on climate change & food often calls for reduced meat eating and plant-based diet, but overlooks the fact many grasslands are unsuitable for continuous cropping. Grasslands support many ecosystem services: watersheds, wildlife, biodiversity, carbon capture, weather, etc. Grazing livestock can contribute to grassland maintenance to turn grass into human food. : carbon storage by plant biomass

2 Reversing desertification is a global warming mitigation strategy because carbon is stored in stable, long-lasting organic matter in soil Karoo Region of South Africa Holistic Planned Grazing average rainfall: 23 cm/year Conversion of semi-desert to healthy savanna = carbon capture of 25 to 60 t C/ha Climate Change Confronting higher stocking densities tightly packed herds frequent movements well-planned rotations no technology, irrigation, or fertilizer mimic behavior of natural herds with predators Conventional Continuous Grazing Improvement in soil and vegetation restores water tables quickens desertification Vegetation cover contributes to evaporative cooling long-term, rapid rotations of crops & livestock Rotations PHOTO: Kroon Family
