No Thumbnail AvailableBook (stand-alone)Environmental Impact Assessment of Landless Monogastric Livestock Production Systems 1996
Also available in:
No results found.In this report, the nature and strength of interactions between “Landless livestock monogastric” production systems (LLM systems) and the environment are discussed, as well as some options for mitigation. Chapter 1 presents the delineation and definition of LLM systems. A general description of LLM systems and its subsystems, the presentation of a classification system and a discussion on some past and future developments is given in Chapter 2. The nature and strength of interactions between LLM systems and the environment is given in Chapter 3. In Chapter 4 a framework for the design of technological and policy options is given, and some options are discussed. -

No results found.Concerns about degradation of forests and other natural resources, growing awareness about potentially adverse climate changes, and a greater consciousness worldwide about the need for protection of the earth’s environment have led to increased attention on agricultural and animal husbandry practices. These concerns are a natural and predictable reaction as human population continues to increase at unparalleled numbers each year. For example, in 1950 there were just 2.5 billion people in the wor ld. Forty years later, in 1990, this planet had 5 billion. By 2025 human population is expected to reach 8.5 billion people. In just seventy-five years-the life span of an average person in an economically developed country-population will have increased more than it did in all the previous history of the world. Little wonder that agricultural scientists as well as non-agriculturalists feel the time has come to take bold action to save our remaining forest habitat, prevent and even reverse land degradation, and develop a plan which will assure future generations of sustainable agricultural practices. This report focuses on worldwide livestock grazing and mixed farming systems in Temperate and Humid-Subhumid Tropic and Subtropic Agroecological Zones. Excluded are all lands of Africa, all Tropical Highlands, and Arid and Semiarid Tropics and Subtropics. The scope of this focus is massive as it includes 60 percent of the world’s people, 50 percent of the pasture land, 65 percent of t he arable land, 59 percent of the world’s cattle, 44 percent of the sheep and goats, as well as similar proportions of other forage-consuming animals. -

Volume III - Grassland-based Systems in Humid and Subhumid Tropic and Subtropic Zones (LGH)
1996Also available in:
No results found.Livestock grazing systems in humid areas (LGH) are most prevalent in South America where countries such as Argentina, Brazil, Columbia, and Paraguay account for 62.6 percent of the agricultural land in the LGH (see Table III.1). China, Australia, and the U.S. account for the remainder with 70 percent of the LGH human population and 18 percent of its agricultural land in China. This category represents about 75 percent of the livestock grazing systems in humid zones worldwide with the remaining 2 5 percent in Africa. The agricultural land in the LGH is 88 percent pastureland but is rather densely populated at the rate of 1.9 ha/capita overall and 0.5 ha/capita for China. The LGH represents about 13 percent of the world’s pastureland and accounts for 12 percent of the world’s cattle, and 6.4 percent of its sheep and goats (Table III.2). As with the agricultural land, South America accounts for the majority of the LGH cattle (83 percent) and sheep (57 percent). However, most of the go ats (57 percent) are found in China. Significant numbers of sheep are found in Australia and China. Livestock feed demand (based on livestock unit equivalents) for the three types of livestock in the LGH comes primarily from cattle (89 percent).
