Since pollution of many sorts can directly and indirectly hurt the soil, it can significantly contribute to the desertification It is estimated that about 60% of total agricultural and livestock sectors is already affected by desertification [27,74]. Found insideAs indicated by Nelson (1990), the advancing sand dune is a popular myth and/or misconception of desertification. ... in contrast to socio-economic and political factors, which constitute the indirect causes of desertification. in the use of pesticides and fertilizers in order to prevent desertification and several other environmental issues. contribution to fight desertification and to ensure a livable future for billions of people on our planet. . 5. Similar to the consumption issue, we should also try to avoid waste on a daily basis, since it indirectly contributes to the More people in an area inevitably exert a greater pressure on that area's resources; sometimes this pressure is indirect, as when growing urban populations place demands on food production in uncrowded In our current age, large areas of forests have to be cut down or burned in order to get more space for farming to produce In turn, this also often Found insideSecond in the series of TERI s annual flagship publication on global sustainable development, People, Planet and Progress Beyond 2015 examines six critical issues of the Planet (climate change, ozone layer depletion, loss of biodiversity, ... It is the spread of arid areas caused by a variety of factors, such as climate change (particularly the current global warming) and overexploitation of soil as a result of human activity. land into an arid desert-like environment. Rangeland degradation could be because of numeral factors, such as an unnecessary increase in animal population leading to overgrazing of the natural vegetation, soil erosion, human interference and climatic variables. Therefore, also the excessive cultivation of cattle can lead to significant problems with desertification in the long This means that you should not by products that are excessively packaged. Desertification is a big global problem, which will become even worse due to the effects of global The two external, or driving, forces are limited land resources and increase in rural population. In turn, even rather harmless diseases may take the life of many people since their immune system has become quite weak over Since desertification implies the destruction of the livelihood of many farmers, it also contributes to serious migration movements. Especially in areas that have been poor for a quite long time, people in those areas often do not have any Deforestation causes can either be direct or indirect. Since mining often implies the destruction of large areas of land, mining practices should be confined by governments so that Problems of water scarcity, groundwater depletion, soil erosion, and salinization have all been recognized as outcomes of deeper policy and institutional failures. In some areas, this led to intercultural conflicts and desertification as herders and farmers claim access to and use of the same land. The driest lands were reserved for nomadic herding. general public, acid rain can alter the natural conditions of many plants and may lead to serious decrease in crop yields over time. This summary is free and ad-free, as is all of our content. This situation may be further exacerbated by global climate change. . Desertification is land degradation in drylands. From this time on, I wanted to make a contribution to ensure a livable future for the next lead to serious soil pollution. In extreme cases, poverty and hunger may also turn into starvation. This causes desertification. Globalization can either contribute to or help prevent desertification, but it creates stronger links between local, national, sub-regional, regional, and global factors related to desertification. . desertification issue can be mitigated to a certain extent due to a reduction in mining actions. savings and may no longer be able to get enough food due to the desertification issue, which may take the life of a high number of people. In the long run, acid rain can also contribute to desertification, In the deserts of the Southwest, the average precipitation is less than 3 inches per year. ≥ Geography Resource Combating Desertification 'What makes the desert beautiful is that somewhere it hides a well' The ", These factors lead to decreased land productivity and a downward spiral of degradation and poverty (Figure 1.1). order to extract those resources, we have to mine large areas of land, which may turn into arid land once those mining processes have been finished. Irrigation can cause environmental problems such as waterlogging, salinization, water pollution, eutrophication, and excessive groundwater use. A synthesis of the environmental and climatic history of every major desert and desert margin, for researchers and advanced students. Since overpopulation indirectly contributes to desertification through excessive pollution and a contribution to global Deforestation and overgrazing brings about marked changes in the climate of the area like changes in rainfall, temperature and wind velocity causing soil erosion and increased dust particles in the atmosphere. In contrast, the average precipitation in the This can drive down prices on the international market, and have often undermined the livelihoods of many food producers in poorer countries. This publication, prepared jointly by the WHO, the World Meteorological Organization and the United Nations Environment Programme, considers the public health challenges arising from global climate change and options for policy responses, ... Therefore, it 5. Such distortions to international food markets drive down prices and have often seriously undermined the livelihoods of food producers in many poorer countries. significant damage to the soil. In 2002, industrial countries spent more than $300 billion on their agricultural sectors—about six times the amount allocated to foreign assistance. CAUSES OF DESERTIFICATION. desertification since excessive consumption contributes to the emission of greenhouse gases, which in turn contributes to global warming. 8. For example, according to Berry (2003), the cause of land degradation involves two interlocking complex systems: the natural ecosystem and the human social system. might make sense to fight deforestation and plant trees in the affected areas, not only to prevent desertification but also to fight additional environmental issues. Conversely, this makes public policies and physical infrastructure useful intervention points. Inappropriate farming systems such as continuous cultivation without adding any supplements, overgrazing, poor land Desertification may also lead to serious levels of poverty. - ice age - tsunami - global warming - large asteroid impact However, in order to get rid of this 4.1 What social, economic, and policy factors can contribute to desertification? Among direct causes are: Natural causes as hurricanes, fires, parasites and floods. In general, famers should reduce their use of fertilizer and pesticides. Desertification is caused by multiple direct and indirect factors. For instance, if some regions suffer from water shortages due to climate change, animals in those regions may suffer from the Poverty caused by desertification may also lead to serious levels of hunger. These include indirect . In other cases, enlarged markets can also contribute to successful agricultural improvements. How are desertification and human well-being linked? However, this excessive optimization of farming will hurt the soil and will eventually turn into the desertification of land in the long run. Sedentarization of nomads in marginal drylands and other limitations to their transboundary movement lead to desertification because they reduce people’s ability to adjust their economic activities in the face of stresses such as droughts (R6.2.2, C22.3.2). When farmers and herders lose control or long-term security over the land they use, the incentives for maintaining environmentally sustainable practices are lost, and this can greatly contribute to desertification. The indirect economic and social costs suffered . 6. news! Which is a cause of desertification? Although desertification has been curbed in some areas, it is still expanding at a rate of more than 67 km 2 every year. The synergistic behavior among pastoralists and farmers is driven by both governmental policies and favorable market opportunities; the two groups cooperate when it is in their own vested interests (see Key Question [How can we prevent or reverse desertification?]) What are the major causes of desertification? If the decline in population is severe enough, Since an intact soil and plants filter our water, the absence of those factors due to desertification may, Since desertification implies the destruction of the livelihood of many farmers, it also contributes to serious, Stricter regulations regarding farming practices. [24] - [27] ). This book is the result of a joint research effort led by the U.S. National Academy of Sciences and involving the Royal Scientific Society of Jordan, the Israel Academy of Sciences and Humanities, and the Palestine Health Council. In places where there are developments in mining and tourism, people are attracted by jobs. However, among countries with a per capita GDP of at least $4,600, net deforestation rates have ceased to increase [12]. For example, a decline in population can result in desertification since there may no longer be enough people to manage the land adequately. This has led to an increase in land degradation and desertification. Desertifica tion is largely synonymous with land degradation but in an arid land context. Deterioration of soil resources is largely human induced. Mining also often implies the pollution of nearby areas. While some species may be able to adjust to the altered environmental conditions properly, many species will not be able to do so and Children should be taught from an early age on how our daily But the causes of desertification are complex, and the relationship between two variables such as population and desertification is not clear-cut. Indirect causes of desertification include poverty, population growth and loss of traditional knowledge so public understanding is important." According to Dr. Taoufik Ksiksi, associate professor in biology at the United Arab Emirates University, too many wrong types of animals are overgrazing precious regional land, exposing the soil and . Found inside – Page 169Natural resource degradation usually has direct and indirect causes. For example, desertification can directly result from overgrazing and poor cropping practices, but indirectly result from poverty and population growth. ; 4.2 Does globalization play a role in desertification? farming practices are often not sustainable and can be quite harmful to the soil. Found inside – Page 110Human causes of desertification arguments First , population increase : desertification is blamed on the growth of ... can be the consequence of a complex mix of hidden and apparent causes leading to cumulative or indirect impacts . Programme estimates that one third of the drylands in Africa are affected by. Sustainable ways to reduce land degradation and desertification demand research and advocacy of sustainable land management practices. This book is organized into two sections. Combating desertification and developing a sustainable management program depends upon removing both kinds of causes. Millions of people will likely lose their livelihood and will have to migrate to foreign countries in order to survive. In many areas, farmers only plant certain kinds of plants for many years, which leads to an extraction of plenty of precious resources and minerals out of the Published under the authority of the GreenFacts Scientific Board. Policies favoring sedentary farming over nomadic herding can contribute to desertification. It includes background papers with continental and international perspectives dealing with land degradation and desertification studies. The book assembles various topics of interest for a large audience. These include poverty, population growth and loss of traditional knowledge. The farmers' crops dying would be the "direct" impact of drought. Our consumption behavior is a main problem for the sustainability of our environmental system. Lands turn to desert due to a number of reasons, but much of the desertification that is occurring around the world today is caused by human activity on lands that are extremely vulnerable to overexploitation and improper agricultural methods. Historically, dryland livelihoods have been based on a mixture of hunting, gathering, farming, and herding. For instance, However, if crop yields drop significantly due to desertification issues, many people may lose their livelihood and may be, Poverty caused by desertification may also lead to serious levels of, In extreme cases, poverty and hunger may also turn into, In general, the destruction of habitats and the desertification may also. desertification of land in the short term. Our forests are quite important since they contribute to a natural balance and provide a habitat for many Many plants are quite sensitive to their This is the first time that a global, baseline status report on land and water resources has been made. Indirect causes of desertification 5. Desertification is one of th e most serious environmental and socio-economic problems in the world today, and China is a developing country with vast desert-affected areas, covering in total 471 counties in 18 provinces and autonomous regions. The dealership closing would cause many more impacts in the community. Studies have shown that, in dryland areas, trade liberalization, macroeconomic reforms, and a focus on raising agricultural and livestock production for exports can sometimes lead to desertification. There are also several indirect causes of desertification. Global trade regimes and linked government policies influence food production and consumption patterns significantly and affect directly or indirectly the resilience of dryland ecosystems.Improved access to agricultural inputs (like fertilizers, pesticides, and farm machinery) and export markets typically boosts productivity. Historically, dryland livelihoods have been based on a mixture of hunting, gathering, cropping, and animal husbandry. Excessive intensity and frequency can lead to irreversible changes in ecological processes and, ultimately, to desertification. Desertification is taking place due to indirect factors driving unsustainable use of scarce natural resources by local land users. An increased population is putting greater pressure on the environment for resources such as wood and water. https://en.wikipedia.org/wiki/Desertification, https://www.nationalgeographic.com/environment/habitats/desertification/. If these people lose their jobs due to desertification, the poverty issue Desertification is a big global problem, which will become even worse due to the effects of global warming. These include indirect factors such as population pressure, socioeconomic and policy factors, and international trade as well as direct factors such as land use patterns and practices and climate-related processes. "They include overgrazing, overcultivating, deforestation and poor. Causes of Desertification • Desertification is the degradation ofdrylands--loss of biological or economic productivity and complexity in croplands, pastures, savanna, steppe and woodlands. Also, our global demand for food is increasing. By, Another contributor to desertification is, In turn, once most of the natural resources have been extracted and mining is no longer profitable in the respective area, Cancer rates and mortality, types and causes, Endocrine disrupting properties of pesticides. may even be exacerbated. which could hold the soil together. However, if this area is not used for other purposes for some reason, chances are that this area turns into arid land. (See the discussion of MA scenarios in Key Question [How will different future development paths affect desertification?]) The harsh and unpredictable climate combined with changing socioeconomic and political factors has forced dryland inhabitants to be flexible in land use. View Notes - Desertification.pdf from ENS 102 at Maseno University. basis. This 2nd edition reflects major advances in our understanding of desertification over the past few years and has been thoroughly revised and expanded to almost twice its original size. 2. Indirect Economic Costs • … are incurred through off-site impacts that can be some distance from the land use that is the source . In successful communal systems, greater transparency and fairness in the allocation of resources to all stakeholders is essential. The indirect economic and social costs suffered outside the affected areas, including the influx of "environmental refugees" and losses to . UNCCD: United Nations Convention to Combat Desertification- Composed of the international community, recognized that desertification is a major economic, social and environmental problem of concern to many countries in all regions of the world and developed integrated approach to the problem, emphasizing action to promote sustainable development. order to mitigate the adverse effects of desertification, governments all over the world have to set strict regulations. endangered or even extinct. For mining, large areas of land have to be used. Moreover, many people are also employed by farmers. Irrigation has led to increased cultivation and food production in drylands, but in many cases this has been unsustainable without extensive public capital investment. In other cases, enlarged markets can also contribute to successful agricultural improvements. Corrupt government officials may accept bribes from illegal loggers and offer access to protected forest areas in return. Since in our nowadays world, farming practices are fully optimized for the highest possible yields, this also often implies 2. In these issues. Where conditions permit, dryland populations can avoid degradation by improving their agricultural practices and enhancing pastoral mobility in a sustainable way. is the ultimate driving force behind desertification. This in turn depends on the socioeconomic resources available, the policies adopted, and the quality of governance. the acidity level of the soil, which may lead to the extinction of many plant species. This in turn implies that large areas of land that have been used for farming in the past will become arid and will no longer Share it! How are desertification and human well-being linked? the excessive use of fertilizers and pesticides in farming in order to maximize crop yields. desertification at moderate or high . Found inside – Page 430Y 4 A Desertification is caused by factors that directly and indirectly influence the land. ... The primary indirect causes of desertification are climate factors, tech— nological innovations, economic factors, institutions, ... Desertification may also lead to a loss of habitats for many animals and plants. The majority of dryland areas (65%) are rangelands that are more suited to sustainable pastoralism than crop production. This can be a serious issue, since in many areas worldwide, people rely on clean groundwater for showering Therefore, it is crucial to adjust our consumption to a more sustainable level in order to fight desertification. Direct agents and causes of deforestation, also typically referred to as sources of deforestation, first level . If we see above pattern, almost all the causes of desertification are man made directly or indirectly. Desertification: Desertification is the process leading to desert formation. Over-exploitation and inappropriate land use: the practice of inappropriate agricultural produce, overgrazing, over cultivation and deforestation are major issues that causes desertification in northern Nigeria. The main causes of desertification include a mixture of social, economical and political factors. However, in order to meet the demand for material goods, large amounts of resources have to be processed by industries. Chapter III describes the causes of desertification. Causes of desertification: Desertification occurs due to numerous factors, primarily anthropogenic causes, which began in the Holocene era and continues today. diseases. 2003). currently faces. Human activities as agricultural expansion, cattle breeding, timber extraction, mining, oil extraction, dam construction and infrastructure development. Chapter 3. In both cases, the use of fire promotes the service of nutrient cycling and makes nutrients stored in the vegetation available for forage and crop production. to the desertification of the grazing areas since plants have no chance to recover in population and may also eventually die off due to excessive manure from those animals. Natural factors are also a main cause of desertification. This book describes the common psychiatric conditions, their key features and how they may influence cardiovascular disease, outcomes, and quality of life. be suitable for farming anymore due to a lack of water. This mixture varied in composition with time, place, and culture. turn into grownups, they are also more likely to behave in a greener way. Since trees are a natural storage space for greenhouse gases like carbon dioxide, if these trees die off, large amounts of greenhouse gases that had been stored in those trees are now emitted However, removing international trade barriers without regulation at national level may also encourage unsustainable agricultural practices. How can we prevent or reverse desertification? In such irrigation approaches, rivers are often disconnected from their floodplains and other inland water habitats, and groundwater recharge has been reduced. 4. Chapter V gives an analysis and evaluation of the 1992 National Plan of Action to Combat Desertification. Security of tenure does not necessarily imply private property rights; many long-established collective and community-based management practices have operated quite effectively. In our current age, acid rain has become a significant environmental issue. These include indirect factors such as population pressure, socioeconomic and policy factors, and international trade as well as direct factors such as land use patterns and practices and climate-related processes.". problems, including resource depletion and also the desertification issue. If the decline in population is severe enough, species may become chances are that this area will suffer from significant levels of desertification since our, Soil pollution in general can be regarded as significant cause for desertification. In turn, once most of the natural resources have been extracted and mining is no longer profitable in the respective area, 90% of China's desertification occurs in the west of the country. ; 4.3 How can land use affect desertification? desertification. of excessive farming since the soil has been damaged too much over time. Human activities as agricultural expansion, cattle breeding, timber extraction, mining, oil extraction, dam construction and infrastructure development. Millions of people will likely lose their livelihood and will have to migrate to foreign countries in order to survive. Wanna make a contribution to save our environment? Soil pollution in general can be regarded as significant cause for desertification. sufficiently recover from human intervention. If you want to multiply your positive impact on our environment, you should also try to convince others about our environmental This is due to a growing world population, but also due to the The dealer losing money and all of the other impacts would be the "indirect" impacts of drought. By introducing those measures, farming will become much more sustainable since the soil is protected from excessive use and areas that suffer from desertification usually do not have any trees or other bigger plants in place anymore, these areas are more vulnerable to floods and erosion since there is no vegetation Many plants are quite sensitive to their By education these children, they are more likely to behave in an eco-friendly manner. This is caused, and acts in concert with, a number of other factors — including drought, overgrazing, deforestation, common agricultural practices, and changes in the climate. Unappropriate decision making can cause problems of water scarcity, groundwater depletion, soil erosion, and salinization. Over-exploitation and inappropriate land use: the practice of inappropriate agricultural produce, overgrazing, over cultivation and deforestation are major issues that causes desertification in northern Nigeria. This problem will become even worse since due to global warming, large areas of land that are currently used for farming will Land use changes are responses to changes in the provision of ecosystem services, and they also cause changes in this provision. The direct and indirect causes of land degradation are linked by a causal nexus (Figure 9, p. 62). Poverty can cause desertification because poor communities normally use soil with little fertility. 6.1 Causes of Desertification Desertification is caused by multiple direct and indirect factors such as mentioned below. A major effect of desertification is the decrease in crop yields. If their land becomes arid, they Desertification is considered to be the result of management approaches adopted by land users, who are unable to respond adequately to indirect factors like population pressure and globalization and who increase the pressure on the land in unsustainable ways. ground. However, limited controlled fires can play an important role in the management of dryland herding and farming systems, promoting nutrient cycling and forage quality. Due to desertification, the small number of remaining animals or plants may also die off extent. However, if crop yields drop significantly due to desertification issues, many people may lose their livelihood and may be Natural and Anthropogenic activities are the driving forces of desertification. The process of globalization can either contribute to desertification or help prevent it. Our overall level of consumption is increasing on a steady rate. desertification. 7. It also contributes to In this article, the causes, effects and solutions for desertification are examined. As they use the soil it further downgrades the soil and makes the land desert. Among the typical direct causes of desertification in the region are poor agricultural practices. Since overpopulation indirectly contributes to desertification through excessive pollution and a contribution to global Overpopulation and population growth increase the requirement for several resources such as food and infrastructure. If this is not the case due to insufficient food supply, chances are that our body is more vulnerable to be able to get enough food. The consequences of such changes include the loss of soil organic matter, erosion, loss of biodiversity, and habitat changes for many plant and animal species (C22.3.3, C22.4.2, C22.5.1).
