Holistic Grazing Management Alvaro Rigel Gallegos Rivero, Ralf Otterpohl Holistic Grazing Management Alvaro Rigel Gallegos Rivero, Ralf Otterpohl “The technology we wield today has greatly expanded the ways in which we can alter our environment and that, combined with the exponential increase in our numbers, has magnified our potential for causing damage. How, more than ever, we require the ability to make decisions that simultaneously consider economic, social and environmental realities, both short and long term. Given an appropriate framework for organizing management and decision making, we should be able to do this.” (Savory 1998, p.7) Abstract The demand for food increases globally and this increase is exponential. To supply such a vast demand, farmers try to intensify the productivity of their land and livestock. Measures are mostly taken based on short term outcomes. This type of production is mostly not sustainable. Soil is depleted from its nutrients and organic matter and erosion is increasing dramatically, while productivity is dropping. Livestock can have a devastating impact on natural resources, but it also has the capability to restore the health of an ecosystem with substantial economic benefits. Holistic Grazing Management (HGM) has been developed as an ecosystem approach by Allan Savory. Pasture land is subdivided into small paddocks with a one to a few days of grass supply for the whole herd. The choice of paddocks follows a scientific approach and requires good knowledge of the characteristics of land and climate. Empirical practices in several regions of the world show promising and inspiring examples on how agricultural management can create a balance between productivity and ecology. Animal droppings in conventional pasturing will dry out and often be lost to the humus, while in HGM the droppings are coming in much higher volume and will be worked into the ground by hooves. Practical research of Joel Salatin has supplemented HGM with combining cattle grazing the paddocks with utilization of the same plot 3 days later for pastured chicken. These have different food preferences and eliminate parasites in the cow dung by feeding on them, too.

It is important to understand the relationship between an increasing demand for livestock products, erosion and exploitation of water and soil resources. Holistic Grazing Management (HGM) is an interesting option for sustainable farming. This method is at the same time a way out of ethically inacceptable livestock farming, which gives animals free range and natural fodder. This ensures product quality, whilst reducing the ecological footprint, especially important in times of a rising demand for grass-fed livestock (Pollan 2006). Cereals roots and tubers are losing their share in average diets to meat, dairy products and oil crops (FAO 2017; Harrison 2002). Between 1960 and 1999, meat consumption in developing countries rose by 150 %, and that of milk and dairy products could rise by further 44 % (Harrison 2002, p. 5). Between 2000-2010 there was a global growth in production of meat of 2,6 % and a 2,5 % of eggs, milk, and processed milk (FAO 2013, pp. 172–6). In developing countries, the demand grows faster than production, causing a trade deficit. Meat production will rise steeply from 1.2 million tons in the late 1990’s to 5.9 million tons in 2030, despite the fast growing exports from producing countries in Latin America, while in milk and dairy products the rise will be less steep but still considerable, from 20 million to 39 million tons per year. It is projected that the growth will be boosted by industrial enterprises. Production from recent years shows a growth twice as fast as that from traditional mixed farming systems and more than six times faster than grazing systems (FAO 2013; FAO 2017; Harrison 2002). The shift towards unsustainable practices takes place on different scales, from small-scale farmer driven deforestation to large scale deforestation driven by distant urban growth (Biello 2010). Conventional Livestock Production: Environmental Impact Livestock’s role in deforestation is of particular importance, especially in tropical rainforests, where the largest net losses of forests and resulting carbon losses occur. In tropical Latin America 2 for example, land used for extensive grazing has increased continuously over the past decades and most of this increase has been at the expense of forests (Steinfeld et al. 2006). Rainforest conversion is dominated by the establishment primarily of pastures, but also cropland, irrespective of the characteristics of soils, climate regimes, and topography. In addition, soybean and cereal production primarily destined for feed production has unleashed a wave of events leading to the destruction of natural habitats over vast areas through deforestation (Steinfeld et al. 2006). The livestock business is among the most damaging sectors to the earth’s increasingly scarce water resources, contributing, among other, to water pollution, eutrophication and the degeneration of coral reefs. The major polluting agents are animal wastes, antibiotics and hormones, chemicals from tanneries, fertilisers and pesticides used to spray feed crops. Widespread overgrazing disturbs water cycles, reducing replenishment of water resources above and below ground. Significant amounts of water are withdrawn for the production of feed (Matthews 2006). Livestock is a source for air pollution, causing about 50 % of methane, 24 % of nitrous oxides emissions and 26 % carbon dioxide (FAO 2018; Gerber et al. 2013). Holistic Grazing Management – Concept Holistic Grazing was first proposed by Allan Savory, according to whom holistic resource management is a wildlife management technique, even where there are no livestock on the land (Savory 1983, Rangelands, p.155): ‘It is a watershed management technique even where there are no livestock on the land. It is riparian and fish management technique. It is also a method of managing livestock on the land whereby livestock can be used to reverse desertification process very economically with or without fencing. It is also a method of managing livestock on ranges or on planted pastures whereby greater production can be achieved both from the land and the animas and with greater profitability than conventionally. It is a method of making conventional range management techniques economically sound there they were economically unsound.’ According to HGM concepts, agriculture in its commercial form is producing more eroding soil than food, while transportation and energy play an equal, if not lesser role, as ecosystem deterioration on GHG emissions. The problem with ecosystem deterioration is that, due to human intervention, the ecosystem cycles are already broken and cannot preserve natural cycles which support life. The Holistic Grazing view is that livestock needs to be managed correctly to preserve these cycles and thus, the ecosystems (Coughlin 2013). Grass that is not consumed does not biologically decay; it turns into dead dry matter, woodier in texture, which is no longer consumed by animals. Since it has not decayed, it oxidizes over long periods of time, not allowing the natural process of decay to occur and therefore not allowing 3 new grass to grow during the next year or growing season. This eventually smothers and kills the grasses in the area, allowing for woodier vegetation to grow, clearing soil from grass and therefore releasing carbon

  • Regeneration of Soils and Ecosystems: the Opportunity to Prevent Climate Change
    REGENERATION OF SOILS AND ECOSYSTEMS: THE OPPORTUNITY TO PREVENT CLIMATE CHANGE. BASIS FOR A NECESSARY CLIMATE AND AGRICULTURAL POLICY. From the International Year of the Soils and Paris COP21 to the Decade on Ecosystem Restoration 2021-2030 SUMMARY We are probably at the most crucial crossroad of Humanity’s history. We are changing the Earth’s climate as a result of accelerated human---made Greenhouse Gases Emissions (GHG) and biodiversity loss, provoking other effects that increase the complexity of the problem and will multiply the speed with which we approach climate chaos1, and social too: --- Climate Change: A Risk Assessment: The report argues that the risks of climate change should be assessed in the same way as risks to national security, financial stability, or public health. (http://www.csap.cam.ac.uk/projects/climate---change---risk--- assessment/). --- “Over---grazing and desertification in the Syrian steppe are the root causes of war” (http://www.theecologist.org/News/news_analysis/2871076/overgrazing_and_des ertification_in_the_syrian_steppe_are_the_root_causes_of_war.html). We explain and justify scientifically the need to give absolute priority to the regeneration of soils and ecosystems. The sustainability concept has driven positive changes but has failed on two levels: it has been easy to manipulate because of its inherent laxness, and because of the fact that since the Earth Summit (Rio de Janeiro, 1992) indicators show much worsening and certainly no improvement. Global emissions increase and soil erosion is every year hitting new negative records. Ecological and agrosystem regeneration necessarily implies a change for the better, a positive attitude and the joy of generating benefits for all living beings, human or not.

  • A Global Strategy for Addressing Climate Change 1
    A Global Strategy for Addressing Global Climate Change by Allan Savory Allan Savory, recipient of the 2003 Australian International Banksia Award for the person or organization doing the most for the environment on a global scale, wrote the book ""Holistic Management: A New Framework for Decision Making" (Island Press 1999) with his wife Jody Butterfield. He is one of the few scientists who have worked on global environmental malfunction for half a century from a holistic point of view, a viewpoint that is now gaining increasing acceptance with the growing awareness of global climate change. In 2010 Savory’s work in Zimbabwe, demonstrating the reversal of desertification using increased livestock, won the Buckminster Fuller Challenge Prize for the strategy offering the most hope for dealing with humanity’s most pressing issues. A Global Strategy for Addressing Climate Change 1 Executive Summary. Introduction A Two-Path Strategy is Essential for Combating Combat Climate Change 1. High Technology Path. This path, based on mainstream reductionist science, is urgent and vital to the development of alternative energy sources to reduce or halt future emissions. 2. Low Technology Path. This path based on the emerging relationship science or holistic world view is vital for resolving the problem of grassland biomass burning, desertification and the safe storage of CO2, (legacy load) of heat trapping gases that already exist in the atmosphere.

  • Holistic Management Case Studies, Profiles and Articles
    Holistic Management Case Studies, Profiles and Articles For many years, large areas of grasslands around the world have been turning into barren deserts. This process, called desertification, is happening at an alarming rate and plays a critical role in many of the world’s most pressing problems, including climate change, drought, famine, poverty and social violence. One major cause of desertification is agriculture – or the production of food and fiber from the world’s land by human beings for human beings. In the past, large wild herds of grass-eating herbivores migrated and were pushed along by predators over the grasslands. These herds grazed, defecated, stomped and salivated as they moved around, building soil and deepening plant roots. Over time, the wild herds were largely replaced by small numbers of domestic, sedentary livestock and populations of predators were mostly destroyed. Without the constant activity of large numbers of cattle, the cycle of biological decay on the grasslands was interrupted and the once-rich soils turned into dry, exposed desert land. Over forty years ago, Allan Savory developed Holistic Management, an approach that helps land managers, farmers, ranchers, environmentalists, policymakers and others understand the relationship between large herds of wild herbivores and the grasslands and develop strategies for managing herds of domestic livestock to mimic those wild herds to heal the grasslands. Holistic Management is successful because it is a cost- effective, highly scalable, and a nature-based solution. It is sustainable because it increases land productivity, livestock stocking rates, and profits. Today, there are successful Holistic Management practitioners spread across the globe, from Canada to Patagonia and from Zimbabwe to Australia to Montana.

Internet [email protected] 1 A Dynamic and Stochastic Perspective on the Role of Time in Range Management Abstract This paper uses a new ecological-economic approach to analyze the role of time in range management in a dynamic and stochastic setting. We first construct a theoretical model of a parcel of rangeland in which time restrictions are used to manage the land. We then show how the dynamic and the stochastic properties of this rangeland can be used to construct two managerial objectives that are ecologically and economically meaningful. Finally, using these two objectives, we discuss an approach to range management in which the manager has two interrelated goals. This manager maximizes the profits from range operations and (s)he also takes steps to move the rangeland away from the least desirable state of existence.

  • From the Instructor
    FROM THE INSTRUCTOR In WR 150, “Climate Change: Science and Action,” students grappled with the questions of how and whether our global society can mitigate and adapt to climate change. One of the greatest challenges of the course was for students to examine a real-world problem over which they as individuals have little control. It can be difficult to conceive of an original persuasive argument when you know from the outset that significant sociopolitical barriers stand in the way of implementation. While students weren’t required to present possible solutions, many did. A number of these solutions, Gregory Bond’s among them, were feasible, plausible, and expressed in a way the average educated adult could grasp without specialized knowledge. Because of this accessibility, “Reforestation and Sustainable Investments” is more than a student’s successful assignment: it also exemplifies some of the real-world applications of classroom writing skills. Furthermore, this essay illustrates the author’s evolution, from a non-expert undergraduate student concerned about the topic and invested in learning more, to a knowledgeable science writer laying forth a fresh perspective on climate action. Greg’s essay is a model of the kind of simple, clear logic necessary to bridge the gap between scientific inquiry and public understanding. This piece makes a complex subject simple and comprehensible. Greg worked hard over the semester to reach the point where he understood the nature and breadth of the problem, could synthesize an original approach from multiple sources, and could lead the reader to see exactly why a multifaceted approach to global warming mitigation could be, and perhaps one day will be, effective at stabilizing atmospheric carbon dioxide levels.

  • By Byron Shelton, Savory Institute Congressional Hearing
    September 13, 2016, 2:00PM Written Testimony – by Byron Shelton, Savory Institute Congressional Hearing “21st Century Conservation Practices” Committee on Oversight and Government Reform, Subcommittee on the Interior Room 2154, Rayburn House Office Building, Washington DC Honorable House members. Thank you for taking the time to hear some of the “21st Century Conservation Practices” of land management applicable for both federal and private lands and specifically related to grazing. My name is Byron Shelton. I am the Senior Program Director for Savory Institute based in Colorado. The Savory Institute is named for Allan Savory, a scientist, ecologist, farmer, and rancher from Zimbabwe and the United States who has worked tirelessly over the last 60 years to understand and train others on how to manage land and resources regeneratively. This includes increasing biodiversity of plant and animal life, increasing water holding capacity of the soil, increasing soil building capacity, increasing soil carbon sequestration and nutrient cycling, and increasing capture of solar energy flow. This effort by Allan has resulted in a management process that has come to be called Holistic Management. Managing holistically, as successful management has to do, considers the whole or big picture including economic, environmental, and social ramifications simultaneously. Otherwise we end up taking actions that have many unintended consequences. The actions might be environmentally sound but not economically sound or visa versa and may not meet the needs of the people involved. Savory Institute was formed to promote the large-scale restoration of the world’s grasslands, which include the croplands of the world, as most crops are grown on soil created by productive grasslands.
