problems and management of grasslands

New York: American Geographic Society. Grasses are very common but very important. Water management. Sandford, S. 1983. Whatever the reasons, fragmentation of scholarship along disciplinary and institutional lines remains a feature of grassland science in China and is evident in the findings of this study. 1981. Oregon State University Pielke, R.A., G. Dalu, J.S. Latitude, soil and local climates for the most part determine what kinds of plants grow in a particular grassland. Discuss the role of grazing in a pasture-livestock system. These studies cast doubt on the premise that pastoralism leads inevitably to the destruction of rangelands. Proceedings of the Conference on Common Property Resource Management. Although accepting the essential differences between pastoral and agrarian peoples, Lattimore (1940) was the first to draw attention to the importance of interactions between these ways of life. Grasslands are threatened by habitat loss, which can be caused by human actions, such as unsustainable agricultural practices, overgrazing, and crop clearing. Although true open-access commons, such as the atmosphere or ocean floors, exist, they are the exception. The "Dust Bowl" was a rude wake-up call that mismanagement can quickly bring destruction to the grassland continuum. Later work, by Barth (1961), Khazanov (1984), and other anthropologists, went further to stress the interdependence of nomadic and settled societies. Discuss the importance of soil fertility and the appropriate use of fertilization. The preservation of these wild ungulates, which is essential for conserving biodiversity, may also make better economic sense than the recent practice of displacing wildlife with domestic livestock. Based on feedback from you, our users, we've made some improvements that make it easier than ever to read thousands of publications on our website. Discuss the advantages and disadvantages of pasture establishment. Technical Report A-4, UNESCO-UNEP Integrated Project in Arid Lands, Nairobi. This phenomenon has been attributed to various factors: an organizational structure that places resources in the hands of research institutes concerned only with their distinct, separate missions; a personnel system that allows for little mobility of students and scholars from one institution or part of the country to another; a centrally planned economy that offers few incentives for communication between researchers and producers; or cultural traits that mitigate against the free and open sharing of information. Stebbing, E.P. During the Qing Dynasty (1644–1911), Han farmers were forbidden to settle in the northern grasslands, a region the ruling Manchus sought to preserve for other minority peoples who were their natural allies. Demographic equilibrium among the pastoral peoples depended on slow, steady settlement, which drew off surplus population and kept a favorable balance between people and resources on the steppe. During winter, of course, this area would be dormant. Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Social studies have been even further removed from the grassland agenda. Discuss the practical applications of regrowth mechanisms. Sinclair, A.R.E., and J.M. Describe how knowledge of grass regrowth is beneficial to forage managers. It is especially important to consider the problem of livestock numbers in the context of herding systems and strategies. Define forage quality and management decisions that increase forage quality. The encroaching Sahara: The threat to the West Africa Colonies. on the hoof. 1991. 1932. More research is needed, however, to provide an adequate understanding of these questions and a sounder basis for rangeland management practices. Nature 349:280–281. Combatting Desertification and Rehabilitating Degraded Population Systems in Northern Kenya. 1988. List several poisonous plants found on croplands, pasturelands, rangelands, and forests. View our suggested citation for this chapter. The fate of wildlife on the grasslands of China gives cause for concern. Most definitions fix the responsibility for desertification on humans or on a combination of human and natural factors. The extent and intensity of damage and the policies needed to reverse these trends are different in each case. Therefore, it is difficult to say whether increases after 1949 represent absolute gains or simply a return to some historically sustainable norm. Discuss the utilization of a yearly grazing calendar. For example, some of our Chinese colleagues point to figures that show an exponential growth in number of livestock in China as an explanation for degradation or even desertification of the grasslands. 1988. Describe conditions that tend to favor weed problems in pastures and describe how to alleviate these conditions. New York: American Museum of Natural History. Describe the benefits of BNF in economic and environmental terms. The number of migrations depended on the quality of the pasture and the availability of water: groups with dependable pastures and water supplies returned each year to a few fixed campsites, whereas those with access to more marginal resources moved more often. In 1932, the central Asian explorer Roy Chapman Andrews described the huge herds of Mongolian gazelles on the eastern steppe. Lamprey, H. 1988. Traditional pastoral nomadism in China depended on the exploitation of extensive, seasonal pastures. One of the keys to this transition is new technologies, such as computer modeling and remote sensing, and the skill to use them. 1989. Fire alone is ineffective against smooth sumac because, while the aerial stems may be top-killed, the plant will resprout from root buds. Rangeland surveys should look beyond livestock production to consider the protection of key habitats. The cultural distinctness and geographical isolation of the nomads reinforced this interpretation. The proportion of each species within a herd normally reflected the constraints imposed by local ecological conditions: more cattle in wetter regions, more goats than sheep in marginal pastures, more camels along desert margins and yaks in the highlands. Most grassland weeds such as docks and thistles are suppressed by the annual hay cut in July and will gradually decline with good management. When we service your septic tank we will empty it and legally dispose of the waste. Changing trends in the World Bank's lending program for rangeland development. The factors preventing establishment of such taller, woody vegetation are varied. Brown (1971) argued that pastoralists were irrational because they conducted dairy operations in environmental settings suited for beef production. Nomads and the Outside World. Their vast acreage, the grasses that grow to be over 10 feet tall, their climate characteristics, and the animals that forage on them have all been natural protectors of the grasslands. To search the entire text of this book, type in your search term here and press Enter. A wide array of maps and accompany-. More than 200,000 Mongolian gazelles migrate between the eastern steppes of Mongolia and Inner Mongolia. Generally speaking, grasslands, or rangelands, as they’re sometimes called, are open areas without trees. None of China's major centers of grassland science has paid significant attention to the role of domesticated animals in the context of the grazing system. Binns, T. 1990. 1989. Natural resource management, agriculture, horticulture and forestry; Look Inside . The "Dust Bowl" was a rude wake-up call that mismanagement can quickly bring destruction to the grassland continuum. In this situation, individual producers may find it rational to ignore the rules, which result in a tragedy of the commons. I want this title to be available as an eBook. However, transformation rates are high: between 1986 and 2002, grassland areas suffered losses of 16%, which corresponds to a loss rate of 1000 km 2 per year ( Cordeiro and Hasenack, 2009 ). Explain the reasons why forage plant identification is important. Describe the importance of irrigation in producing forages. 1990. Since summers can often reach high temperatures in temperate grasslands and the rate of precipitation can be mild, drought is often likely. For these and other reasons, the elimination of small mammals could have a long-term negative impact on rangelands. The temperate grassland biome faces various environmental threats, namely drought, fire, and conversion to farmlands by humans. Because pastoralism is a risky business in which animals quickly gained can be just as quickly lost to bad weather, disease, or theft, large numbers of animals act as insurance against disaster. List and discuss factors that affect irrigation efficiency. All rights reserved. Governing the Commons: The Evolution of Institutions for Collective Action. Rodd (1938) disputed both claims, insisting that Stebbing did not understand variable weather conditions and ecosystem response in the Sahara region. NATIONAL GRASSLANDS MANAGEMENT A PRIMER Appendix C Wooten, H. H. “The Land Utilization Program 1934 to 1964 – ... of land use problems began to appear. Pastoralists also cultivated relations with settled agrarian communities, exchanging wool, meat, milk products, and hides for grain, cloth, tea, and manufactured goods. Desertification Control Bulletin 17:8–12. Stability of African pastoral ecosystems: Alternate paradigms and implications for development. This volume describes one of the most extensive grassland ecosystems and the efforts of Chinese scientists to understand it. Compare and contrast the types of storage and discuss the advantages and disadvantages of each. Mongolia, for example, has attempted to manage gazelles by protecting and harvesting a certain number each year for the European luxury meat market—a program that suffers in part because the gazelles migrate seasonally into China where they are slaughtered indiscriminately. Because under these circumstances private benefit exceeds private cost, each owner is encouraged to continue adding animals to his herd, leading inevitably to overuse and degradation. Khazanov, Anatoly M. 1984. Department of Crop and Soil Science Traditional conservation on Tibet's northern plateau. On most soils there will be some initial problems with perennial weeds. As this study points out, vast areas of China's grasslands are unusable, because they are too dry, too remote, too degraded, or suffer from some other limitation. But a more serious problem is access to training. When material- or man-caused global climate changes occur, what is the expected influence on the seasonal and spatial landscape of the northern China grasslands? The line has been drawn by nature, for it distinguishes the lands that have sufficient moisture to support cultivation from those that do not. They know that ecosystem science in the West has developed conceptual frameworks, methodologies, and techniques that take account of this complexity, and they want to learn and apply these approaches to the study of natural resources in China. Smooth Sumac Management Smooth sumac invades many grasslands, reducing forage production and accessibility under the dense sumac canopy. Vast areas of grassland depend on the availability of water so that they can host grazing species or livestock. Similarly, 21.2% of all grasslands in northern China are judged unusable (see Table 1-1). Discuss the environmental benefits of forages. Conservation, for whatever purpose, must begin with research. Where members of such groups share similar production objectives and methods, where there are no large differences in wealth or social status, where group membership has important benefits in addition to those connected with production, and especially where rules governing resource use are effectively enforced by the group or by some. Despite these problems, China's rangelands continue to support a variety of wild ungulates: the goitered gazelle (Gazella subgutturosa ), Przewalski's gazelle (Procapra przewalski), Tibetan gazelle (Procapra picticaudata), Mongolian gazelle (Procapra gutturosa), Tibetan antelope (Pantholops hodgsoni), wild ass (Equus hemionus), wild yak (Bos grunniens ), argali sheep (Ovis ammon), blue sheep (Pseudois nayaur), Asiatic ibex (Capra ibex), white-lipped deer (Cervus albirostris), red deer (Cervus elaphus), and wild Bactrian camel (Camelus bactrianus). However, the issue is so important for grassland ecology and other fields of interest, that it merits more direct and frank discussion. Given the upheavals in China during the first half of the twentieth century, the number of livestock in 1949—the first year of the People's Republic—must have been below, perhaps far below, levels achieved earlier or obtainable under normal conditions. Our technicians are trained to spot early warning signs that you would probably not notice. But when man has finally been able to conquer the grasslands with the help of inventions, new medicines, better nutrition, and improved transportation, the cycle of give-and-take between soil, plants and animals has been interrupted. Hellden (1988) cites several definitions of "desertification" and finds that all include the notion of decreasing productivity leading to long-lasting, possibly irreversible desertlike conditions. The management goal of these BMPs is to maintain the open, grassy conditions necessary for successful breeding by grassland … In the United States, cheatgrass can overwhelm former areas of native grasslands. Such imagery demonstrates, first, that there is a large seasonal response of the grasslands to the changing weather; and second, that there is considerable spatial structure in this landscape. Of these, sheep and horses were most important, but most herders preferred to keep a variety of animals, in an effort to achieve security against sudden, catastrophic losses of any one species, and self-sufficiency by offering the widest range of animal products. Provide the basic vocabulary for identifying legumes. Practices in other parts of the world suggest that the economic return per hectare from some rangelands can be increased by using a mix of livestock and wildlife rather than livestock alone. Mace, R. 1991. However, Chinese efforts to process and use digital data, to coordinate this date with ground-based measurements, and to construct and manage complex geographical information systems (GIS) are just beginning and are subject to some of the same human and material limitations that have slowed the development of simulation modeling. 1988. Grassland Management Practices in Melghat Tiger Reserve: A Case Study G.D. Muratkar, Dinesh Tyagi, ... Park: Problems and Approaches for Management Niranjan K. Vasu and G. Singh 114 The belief that pastoral livestock management is irrational and inherently destructive has a long history and has been widely accepted by scholars and officials in the international development community (Sandford, 1983). Given the rate of environmental destruction in China and other parts of the world, rangeland research in all countries should incorporate a conservation component, whether it involves concern for the protection of rare species, such as the wild Bactrian camel, or of unique ecosystems, such as the eastern Mongolian steppe. Discuss how livestock interaction impacts grass growth. Switch between the Original Pages, where you can read the report as it appeared in print, and Text Pages for the web version, where you can highlight and search the text. Cambridge: Cambridge University Press. Hellden conceded that crop yields and probably rangeland productivity were severely reduced during a 10-year drought, but maintained that the end of the drought was followed by rapid recovery of both rangeland and cropland productivity. 1986. New Scientist 4:31–32. Cambridge: Cambridge University Press. Explain why producers and the public should be concerned about weeds. In the literature, nomads were presented as survivors of mankind's primitive past, following a way of life that offered nothing to and demanded nothing from outsiders. 3(2):93–100. Controlled-access commons, where natural resources have customary users such as herders, farmers, or fishermen, are more often the norm. As indicated, the pastoral frontier has been defined by a difference in climate, principally rainfall, and its history by the different and changing human adaptations to this reality. Kittel. The arrival of railroads in the 1800's also greatly changed the massive grasslands in Eurasia and North America. Instead, these studies demonstrate that ill-founded assumptions, including herder irrationality, have contributed to the adoption of poor livestock development strategies (de Haan, 1990) and in some instances have actually caused environmental damage and reduction in the economic welfare of the very people the strategies were designed to help. Steppe pastoralists and Han farmers engaged in significant, mutually beneficial trade of grain, metals, medicines, and luxury goods for livestock, furs, and other animal products. Nonlinear influence of mesoscale landuse on weather and climate. 1990b. As recent research in western Tibet has shown, the assertion that pastures are overstocked may be due to new accounting procedures rather than actual increases in herd size (Goldstein and Beall, 1989). Describe the process of inoculation in the production of forage legumes. Pielke and Avissar (1990) and Pielke et al. Locate and describe the tropical grasslands and their forages. Panel members were impressed by the commitment to such changes expressed by scholars in other Chinese universities and research institutes as well. Although extensive pastoralism is associated with the minority peoples of China, not all minorities in the grassland areas are pastoralists. R. Cincotta, G. Perrier, C. Gay, and J. Tiedeman, eds. Do you enjoy reading reports from the Academies online for free? Do you want to take a quick tour of the OpenBook's features? The plant, soil, animal balance is natural but easily upset. Observations made by the two CSCPRC delegations confirm that degradation does occur at specific sites throughout northern China. Forage selection requires an understanding of species and cultivars. Sahelian drought: No victory for Western aid. Low level weed populations may be spot sprayed with a herbicide, or pulled (eg ragwort). Estimate the amount of BNF that is contributed by various crops. The tragedy of the commons. But the content is accessible to anyone who would like to learn more about grasslands. The Inner Mongolia Grassland Ecosystem Research Station at Xilingele is demonstrating how a common research site, open to scholars from throughout China and the world, can produce greater synergy and better results than the all too often insulated research institute, that has been the standard form for the conduct of science in China. © 2020 National Academy of Sciences. In northwestern Tibet and southwestern Qinghai, both remote and almost uninhabited areas, the Tibetan antelope, wild ass, and other unique upland fauna survive in moderate abundance. Native grasslands evolved under a disturbance regime that maintained the grasslands by enhancing native grasses and forbs and suppressing woody growth. Share a link to this book page on your preferred social network or via email. The goitered gazelle, wild ass, wild yak, and Tibetan antelope have declined to a fraction of their former numbers. This frontier has been one of the most persistent and important zones of contact between com-. Yet the greatest environmental damage is generally found around wells or agricultural villages where pastoralists have been settled (Lusigi, 1981; Sinclair and Fryxell, 1985). Pp. Translated by Julia Crookenden. There is ample evidence that statistics gathered after 1949, particularly during political campaigns such as the Great Leap Forward (1958–1960), are highly unreliable. Discuss the considerations of seed quality. Management thus can be considered essential for preservation of grassland biodiversity, as observed in many ‘old-growth grasslands’ (Veldman et al., 2015). Describe several ways in which weeds cause forage crop and animal production losses. National Grasslands Management Review Action Plan (May 1996). Based on field studies, Lamprey (1988) found that from 1958 to 1975, the southern boundary of the Sahara had advanced 100 km. The distribution of photosynthetically active plants over the grasslands of northern China by using a Normalized Difference Vegetation Index (NDVI) is expected to show considerable spatial structure such as observed over the grasslands of the United States (Pielke et al., 1991). Perhaps the greatest impact on China's grasslands, both ecological and social, during the past century has been the massive influx of Han settlers. Discuss the advantages and disadvantages of selecting mixtures. Still, inconsistency in terminology reflects an incomplete understanding of and lack of agreement on the causes, duration, and results of changes in ecosystem status. The ability of grass to endure through periods of drought; to lie dormant in the soil or grow beneath the soil gives grass its greatest advantage. Sign up for email notifications and we'll let you know about new publications in your areas of interest when they're released. Many factors impacted that disaster but better knowledge and management of the plant, soil, animal cycle would have been very valuable. Swift. World Bank, Washington, D.C. Hardin, G. 1968. Other large minorities, such as the Hui in Gansu, Qinghai, and Ningxia, and the Uighurs in Xinjiang, are farmers or traders who practice animal husbandry as an adjunct to village-based agriculture. Expansion and contraction of the Sahara desert from 1980 to 1990. List printed and electronic sources of weed control information. Finally, analysis of the sociology of pastoralism must rest on a careful treatment of statistics. Meanwhile, Yuan loyalists on the steppe attracted Chinese followers from among believers in proscribed religions, such as the White Lotus sect of Buddhism, and erected Chinese-style cities, such as Koko Khota, site of Hohhot, the present capital of Inner Mongolia. Today, the farmer reigns supreme in northern China; the spread of. The once robust village-level traditional institutions, that ensured the sustainable management of grasslands, have broken down and there is no responsible agency to look after the management issues (Anon. Furthermore, an international conference on “Enhanc-ing Economic Viability of Grasslands by Green Farming in Europe” World Bank Technical Paper Number 61. This is the case, for example, where members of the group do not follow similar production strategies, where there are large wealth or status differentials, where group membership has few benefits, and especially where rules about resource use and management are unenforced or unenforceable. Cincotta. For more than two millennia, Chinese have been building fortifications (often misleadingly referred to as "The Great Wall") along a line that runs across Asia, marking the frontier between pastoral societies and practices in the north and settled agriculture in the south. Pielke, R.A., and R. Avissar. Happily, there are signs that things are changing. Origin. Peace, War, and Trade Along the Great Wall: Nomadic-Chinese Interaction Through Two Millennia. The plants provided food and nourishment for animals and the animals, in turn, stimulated growth in the plants, fertilized and distributed seed over the soil. Locate and describe the temperate grasslands and their forages. The Chinese are more advanced in the use of remote sensing, a technique that has helped to develop regional and global approaches to ecosystem science. Such an evaluation is critical not only to understanding local and regional climate and weather, but also as input into global circulation models. Problems and Prospects of Grassland Development: Policy Issues There are a range of government and non-government policies that affect grassland development around the world.
