Allan Savory  Clifford Allan Redin Savory (born 15 September 1935 on a 40,000 acre ranch in Zimbabwe) is a Zimbabwean ecologist, livestock farmer, and president and co-founder of the Savory Institute. He originated Holistic management (agriculture), a systems thinking approach to managing resources. Savory advocates using bunched and moving livestock to what he claims mimics nature, as a means to heal the environment, stating "only livestock can reverse desertification. There is no other known tool available to humans with which to address desertification that is contributing not only to climate change but also to much of the poverty, emigration, violence, etc. in the seriously affected regions of the world." "Only livestock can save us." He believes grasslands hold the potential to sequester enough atmospheric carbon dioxide to reverse climate change. Praised by cattle farmers, his controversial ideas have sparked opposition from other academics; ranging from debate on evidence for treatment effects to the scope of the potential impact for carbon sequestration. Savory received the 2003 Banksia International Award and won the 2010 Buckminster Fuller Challenge. Prince Charles called him "a remarkable man" and noted farmer Joel Salatin wrote, "History will vindicate Allan Savory as one of the greatest ecologists of all time." In contrast, James E. McWilliams described Savory as having "adherence to scientifically questionable conclusions in the face of evidence to the contrary". George Monbiot said of him, "his statements are not supported by empirical evidence and experimental work, and that in crucial respects his techniques do more harm than good." However, this comment has itself been subject to criticism in a later article published in "The Guardian" by Hunter Lovins entitled "Why George Monbiot is wrong: grazing livestock can save the world". Savory was educated in South Africa at the University of Natal, gaining a B.Sc. in Biology and Botany in 1955. According to Savory, he has worked on the problem of land degradation (desertification) as early as 1955 in Northern Rhodesia, where he served in the Colonial Service as Provincial Game Officer, Northern and Luapula Provinces. He also claims to have continued this work in Southern Rhodesia first as a research officer in the Game Department, and even claims to have been an independent scientist and international consultant. He advocated for slaughtering large numbers of elephants up until 1969 based on the idea that they were destroying their habitat. His research, which he claims was validated by a committee of scientists, led to the government culling approximately 40,000 elephants in following years.
