Effects of war. Land degradation refers to a decline in the overall quality of soil, water or vegetation condition commonly caused by human activities. destruction of forest land is to obtain agricultural land. This However, in the context of rapid urbanization, the factors related to EOC and the response of the EOC pool to urbanization down the profile remain elusive. Degrading Air Quality Index. pressure contributes to land degradation and soil erosion, thus affecting productive resource base of the economy. Natural resource degradation in general and land degradation in particular has a great effect on the economies of developing countries. urbanization puts additional pressure on infrastructures that are already weak. Ø Urbanization is mainly a product of demographic explosion and poverty induced rural-urban migration. Air Pollution. 1.1.27 Identify the causes for land degradation. The production of goods and services is made possible through the use of assets or capital such as land, equipment, etc. Meanwhile, the looming effects of climate change threaten large populations in vulnerable geographic areas, where natural disasters and environmental damage are likely to dispro-portionately affect the world’s poor. Measuring the migration effects of land degradation 22 6.1 Measuring and mapping land degradation at global and regional scales 23 Globally, agriculture has met the demands from this rapidly growing urban population, including food that is more energy-, land-, water- and greenhouse gas emission-intensive. Research Center for Advanced Science and Technology University of Tokyo Japan. And many of these have been caused by urbanization and one of the biggest threats that it poses i.e. We explored the effects of high and low-density housing developments on forest-dwelling mammals. Loss of Biodiversity. Water Resources Research, 11, 431-5 6 Chester L. Arnold and C. James Gibbons. Positive effects of Urbanization: • Despite the above disadvantages of urbanization, we must also remain thankful for its benefits. … Land degradation means: 1) Loss of natural fertility of soil because of loss of nutrients. 2) Less vegetation cover 3) Changes in the characteristic of soil. 4) Pollution of water resources from the contamination of soil through which water sweeps into ground or runoff to the water bodies. Due to the uncontrolled urbanization only, environmental degradation has been arising very rapidly and is caused by many problems such as land insecurity, worsening of water quality, excessive air pollution, noise pollution, and the problems of waste disposal. There have been some researches on this relationship from the perspective of the spatial configuration of land use in recent years. Natural hazards are the conditions of the physical environment which lead to the existence of a high degradation hazard, for example steep slopes as a hazard for water erosion. The four indices computed for the study region determines the intensity with which the land surface and land cover is subjected change due to human activities. title: contribution of road transportation to environmental degradation in nigerias urban cities 1 contribution of road transportation to environmental degradation in nigerias urban cities by prof. b.i. global terrestrial land surface and has degraded about 60% of the ecosystems services in the past 50 years alone. Increased stress on land due to concentrated constructions. Problems of Urbanization. The results indicated that there was sig… Urbanization impacts the environment through the strain of resources, including food, water, energy and the land itself, which increases as the population within the urban area increases. Increasing levels of urbanization are caused by natural growth of the urban population and migration of the rural population towards cities. 5.1 Economic problems of Urbanization. Urbanization is another source of land degradation. This Factsheet looks at the causes and effects of water, wind and tillage erosion on agricultural land… Sequential and Unanticipated Cause-effect Situations 4.5 International Research Efforts 5. Forest degradation in the Amazon has facilitated the spread of diseases with potentially large social and economic impacts, both locally and globally. The combined cost to the economy of land degradation and unsustainable soil erosion is estimated at 17 percent of gross domestic product (GDP). The causes of land degradation can be divided into natural hazards, direct causes, and underlying causes. The precipitation or rainfall of the area, that is discharged from the area through stream channels and is thus lost without entering the soil, is called surface runoff. Although agriculture remains the backbone of Pakistan’s economy, many rural people have abandoned agriculture to adopt different occupations as a consequence of rural urbanization. In determining the effects of urbanization on the environment we draw data from weather stations, field interviews, satellite images, and governmental records. costs of using the environment, depletion and/or degradation of the natural asset, etc. Ø Urbanization occurs without industrialization and strong economic base. • Therefore, urbanization leads to deforestation which in-turn affects millions of plant and animal species. Water Resources Research, 11, 431-5 6 Chester L. Arnold and C. James Gibbons. Environmental pollution refers to the degradation of quality and quantity of natural resources. 1.3.1 Understanding Land Use Change and Urbanization This chapter deals with the first question with a theme that urbanization is one of the main causes of land use change, which ultimately causes environmental problems. Based on landscape pattern metrics and ecological risk index, the landscape ecological risk from the landscape pattern dynamics was evaluated. Biodiversity loss: many plant and animal species are threatened with extinction, due to the spread of disease, the destruction and degradation of their habitats, and direct exploitation. problems in India. Urbanization is attractive to many rural citizens for the many opportunities it creates in bettering their quality of life. Soil degradation in urban areas, including sealing, compaction and erosion, has several detrimental impacts on urban welfare and sustainability. Cultivating Steep Slopes 4.2.

Greentumble Environmental Issues February 4, 2016. Urbanization also leads people towards consumerism. 2. The dust bowl of the 1930s in the United States was an example of the negative effects overgrazing, soil erosion and land degradation have on a landscape. FAO highlights that there is a strong relation between land degradation and poverty. Land degradation means: 1) Loss of natural fertility of soil because of loss of nutrients. The aim of the current paper is to investigate possible changes in the distribution of EOC over the soil profile and the impact of land use, socioeconomic, and natural factors on these. Land And Its Impact On The Impact Of Urbanization Of Land Use 1817 Words | 8 Pages processes like mining, housing development, logging and lumbering, agriculture relocation, etc. Land reclamation, which uses coastal land for urban use, is leading to a decrease in coastal forests like mangroves. Economic consequences of environmental degradation. Research Summary We explore and quantify the manifold impacts of urbanization on ecosystems and the services they provide. The majority of Pakistan's industrial sectors, for example fishing and agriculture, which count for more than one fourth of the output and two fifths of employment in Pakistan, are highly dependent on the country's natural resources. Basic Concepts of Deforestation, Degradation, and Fragmentation 2.1 Deforestation Deforestation is the conversion of forested areas to non-forest land use such as arable land, urban use, logged area or wasteland. Estimates on the annual direct cost of land degradation in India. 1.1.26 List the different types of resources from land. Land use and land cover (LUCC) change has been the most visible indicator of the human footprint and the most important driver of loss of biodiversity and other forms of land degradation. Success in fighting land degradation requires an improved understanding of its causes, impact, degree and relationship with climate, soil, water, land cover and socio-economic factors [46]. The impacts may be negative or positive. Hence, in order to sustain economic growth there is a high demand on already scarce natural resources. Index of land degradation. This means that there is a rise in use of elements such as metals, glass and plastic. many parts of the world. From the point of view of environmental accounting, land, water, and air are treated as assets that areused in the production of 3 3.

Environmental Problems of Urbanization. Must have 1 or more of following: 1) … 1995; Brown and Kane 1994), while others argue that land degradation is overestimated and, in any event, relatively unimportantto global food supplies (Crosson 1994). The UN Convention to Combat Desertifi cation (CCD), of which Kenya is a signatory, recognizes land degradation as a global development and environment issue. Besides, it fragments natural habitats, ecosystems and landscapes, affecting biodiversity. Human factors which include deforestation, industrialization and urbanization. "Urbanization and the Natural Drainage System-Impacts, Solutions, and Prognosis." Other kinds of land degradation are as water-logging, chemical contamination, acidification, salinity and alkalinity etc. 2) Less vegetation cover 3) Changes in the characteristic of soil. 4. Land use and land management practices have a major impact on natural resources including water, soil, nutrients and plants, and the living beings. The results showed that the area of Desertification in the West Sahel 4.3. impact for India. Biodiversity 4. This leads to soil erosion, rising water tables, the expression of salinity, mass movement by gravity of soil or rock, stream bank instability and a … Land degradation affects the earth’s productivity. These factors lead to land degradation through erosion. 27 december 2007 . The overall effects of soil degradation pose a major threat to food security especially in poor regions. Population growth and Environmental degradation Population is an important source of development, yet it is a major source of environmental degradation when it exceeds the threshold limits of the support systems. Some of the ways in which traditional land management techniques, closely coupled to environmental constraints, have been These greenhouse gases Show the second major negative impact after the negative effects of greenhouse gases which created by the using of the fossil fuels. Land Pollution One of the calamitous effects of land pollution is the destruction of nearby forests together with its ecosystems. environmental degradation has been occurring very rapidly and causing many problems like land insecurity, worsening water quality, excessive air pollution, noise and the problems of waste disposal. Disposal of Industrial & Agricultural Wastes. plantation degradation .land use and land cover changes in Eleyele catchments area of Ibadan using GIS as a tool to assess changes over a 28 years period (1972 – 2000) of time in the study area.

USF&WS: Lands transitional between terrestrial & aquatic: Lands transitional between terrestrial & aquatic systems where the H 2 O table @ or near ground surface. Air pollution often plagues industrialized cities, particularly during their early … Rural urbanization is taking place rapidly in most areas of Pakistani Punjab. For rapidly urbanizing developing countries, the societal learning required to adapt rural institutions and governance to urban ones became a crash course, leaving little room for timely experimentation and adjustment. Impacts of climate change 20 6. As a result of agricultural land obtaining, greenhouse gases are created at the same time. (Wikipedia) When the environment becomes less valuable or damaged, environmental degradation is said to occur. The resources which are affected include water, air and soil. Major contributing factors included population increase, occurrence of drought, land redistribution, and land degradation. united nations expert group meeting on population distribution, urbanization, internal migration and development If land degradation process continues, it eventually leads to desertification [1]. Integrated solutions and the delimitation of planning regions 6.1. Land degradation occurs slowly and cumulatively and has long lasting impacts on rural people who become increasing vulnerable (Muchena 2008). knock-on effects in the rural hinterland. Research into the causes of land degradation 4.1. Our land, water and soil are compromised when people exhaust resources or release harmful chemicals into the air. 1.1.25 Explain why land is considered as a resource. The process of urbanization resulted in substantial land conversion, which, in turn, led to a drastic decrease in crop production areas and changed the agricultural landscape of the Metropolitan Manila area. Applied with remote sensing, GIS, and mathematical statistics, the spatial-temporal evolution characteristics of urbanization expansion of Yantai city from 1974 to 2009 was studied. : untimely floods, global warming, habitat loss, etc. Environmental degradation is the deterioration of the environment through depletion of resources such as air, water, and soil, the destruction of ecosystems and the extinction of wildlife. Apart from this, urbanization is creating significant environmental stress by disrupting the natural water table, increasing the rates of air pollution and contributing to the overall global warming. Managements of land to sustain that demand need to be considered. 4.9 Drought, land degradation, migration, and violent conflict 19 4.10 Out-migration as a cause of land degradation 19 5. Chapters 7 and 8 are concerned with the economic and social consequences of land degradation: its implications for the community as a whole, and thus for governments, and its effects upon the people, the rural population of the areas affected. Effects Of Urbanization On The Ecosystem. In the table below, the left side shows changes in land and water use when urbanization occurs, and the right side shows the possible effect on the local water system. The Impact of Urbanization on Soils. Lack of Waste Management. Using Quantum GIS (QGIS Development Team 2017), the percentages of forested or wetland and developed land cover with impervious surfaces at each site were quantified.Land-use and land-cover (hereafter, "land use") data were obtained using the 2011 National Land Cover Database, which classifies land use for the continental United States at a 30-m spatial … Unless the relationship between the multiplying population and the life support system can be stabilized, development programs, howsoever, innovative are not likely to yield… Soil degradation means the decline in soil quality which comes about due to aspects, for example, improper land use, agriculture, and pasture, urban and industrial purposes.It mainly involves … With the projected increase in urbanization, this will continue to be a substantial cause of loss of agricultural land, but it is a different problem from land degradation. the loss of ecosystems. With accelerating rates of urbanization worldwide, a better understanding of ecological processes at the wildland-urban interface is critical to conserve biodiversity.

Similarly, average land holding per The Northwest Environmental Journal 7.1 (1991): 93-118. Discharge of various kinds of chemicals on land adjacent to forest regions makes the environment unappealing to the survival of trees, vegetations, and animal species. The major causes of the environmental degradation are modern urbanization, industrialization, over-population growth, deforestation etc. the extent and effect ofland degradation. Multiple pathogens thrive under land-use changes, deforestation, and poverty, causing a significant … Intense human activities and drastic land use changes in rapidly urbanized areas may cause serious water quality degradation. Soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation and soil acidity problems are other serious soil degradation conditions that can accelerate the soil erosion process. Soil degradation causes, effects, preventive methods. Dont miss: Most popular Prelims 2018 test series {syllabus & schedule} 5. Settlements in the city are the major land use activity in view of human demands. Chapter Three 3.1 Population and land degradation processes This section reviews the possible linkages between population factors (population size, geographic distribution, age/sex structures, and changes in these), on the one hand, and the main causative factors, i.e. Dwindling green vegetation. It is found that anthropogenic activities influence urban environment considerably ( Alberti et al., 2003, Andersson, 2006, Lundholm and Richardson, 2010 ), and hence greater attention is required towards monitoring the changes in land use and land cover in urban areas ( Stow & Chen, 2002 ). ADVERTISEMENTS: The following points highlight the five main impacts of agriculture on environment. Forests collect carbon 20 alo, fcsn, fipan, fnes director, centre for environmental human The promise of jobs and prosperity, among other factors, pulls people to cities. Rapid land degradation is recorded in urban areas. Urban soils are subject to sealing, compaction, erosion and contamination. Urbanization changes the hydrological processes and degrades water quality. Urban patterns affect sediment and pollutants connectivity between sources and water bodies. 1. effects of land degradation through water erosion and its subsequent impact on rivers and reservoirs downstream are presented through the use of modeling tools and techniques. I chose this topic because in the past few decades, a lot of natural calamities and phenomena have taken place, e.g. The implications of rapid urban growth include increasing unemployment, environmental degradation, lack of urban services, overburdening of existing infrastructure . The impact of land use change on forest and grassland environments is depicted in 1.4.1. Consequences of land degradation 6. It is urgent, therefore, to act to halt soil degradation and adopt practices to improve soil health. According to FAO, deforestation is the conversion of The Northwest Environmental Journal 7.1 (1991): 93-118. CAUSES OF ENVIRONMENTAL DEGRADATION. un/pop/egm-urb/2008/16 . For example, urbanization of steep slopes has been responsible for many landslides, some of them causing human fatalities, as well as economic and property damage [11]. Urbanization in the Himalayas. discusses the time setting and driving forces behind rapid urbanization in Ethiopia in sections 3 and 4, the economic aspect and characteristics of urbanization in section 5, effects of rapid urbanization on employment, public service provision and spatial organization of towns in section 5. The degradation also impacts our wildlife, plants, animals and micro-organisms. 1.2 OBJECTIVES OF THE RESEARCH The object of this study is to examine the integration of GIS and remote sensing for application Let us find out what surface runoff means. Surface runoff The heavy impact of urbanization on the groundwater quality is shown through the observed high nitrate (up to 295 mg/l as nitrate) and high phosphorus values (about 0.1 mg/l as P). It is clear that the world is becoming more and more urban. The impacts are:- 1. It also placed pressure on urban fringes, making land use conversion inevitable in cities. Urbanization. Based on habitat characteristics, we expected a gradual decline in species abundance across forest-urban edges and … ... the land use, development of an urban fabric analysis in which total vegetative, paved, and ... there has been an increasing trend towards urbanization. 2. Natural factors such as drought, storms on sea, land and deserts such as hurricanes, tornadoes, carina and volcanic eruptions. Degradation of Land 2. Some per ceivethat land degradation poses a potential threatto global food supplies over the long term (Pimentel et al. areas remained land clearing for crop and cattle farming, particularly at present investors are looking the dry land forests to divert in to commercial crops like tea, coffee and rice cultivation [7;8]. 1.1.29 Describe the control measures for land degradation. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. Mining and Urbanization • Surface mining requires the removal of topsoil to get at the valuable rocks below which cause soil degradation. Deforestation is the logging and/or burning of trees in a forested area [9]. However, many elements of urbanization can turn burdensome for a city and its citizens if it is not planned for carefully. BRIEF PRESENTATION OF SENEGAL AND THE CHARACTERISTICS OF ITS URBANIZATION Population: 13,508,715 inhabitants in 2013, 49.9% men and 50.1% women Density: 69 inhabitants per km² Population mostly rural: 54.8% against 45.2% urban Population mostly young: Average age: 22.7 years Active Population: 58.2% of the global population Employment rate: 74.3% in 2013 against 25.7% Air Pollution:With the increase in population and industries the air in urban areas is always polluted with toxic substances. 4 Booth, Derek B. Global Land Project Sapporo Nodal Office Hokkaido University Japan. By 2050, 68% of the world population is projected to live in urban areas. environmental and human health effects associated with high levels of ozone. Better understand land use inefficiencies and measure their impact The causes of distortions (the role of regulations) How land distortions hinder agglomeration effects Misallocation of land (Duranton, Ghani, Grover and Kerr 2015) Study the dynamics of land use Impact on growth? 1.1.28 State the reasons for soil erosion, land slide and desertification. 4 Booth, Derek B. Pressure on land India faces the most acute pressure on agricultural land. Urbanization has been underpinned by the rapid growth in the world economy and in the proportion of gross world product and of workers in industrial and service enterprises. 5 Hollis, G. E., 1975, The effects of urbanization on floods of different recurrence intervals. Increasing levels of urbanization are caused by natural growth of the urban population and migration of the rural population towards cities. It includes definitions, and discussions of land use change, urbanization, and land use planning in the The promise of jobs and prosperity, among other factors, pulls people to cities. Various types of This land transformation in some sense constitutes land degradation for agriculture and grazing. In 1900, approximately 150 million people lived in urban areas with populations of 20,000 or more. 2. Degradation of Land: The degradation of land in one form or the other is matter of serious concern […] Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. Land degradation affects people and ecosystems throughout the planet and is both affected by climate change and contributes to it. The artificialisation of soils can cause a rapid and consequent carbon depletion, which contributes to climate change. It has been predicted that by the year 2050, 70% of the human population on Earth will live in cities [sc:1]. (Bogart and Richardson 2009) The Land-use/land-cover change due to new built-up area is found to be 13 % between 1973 and 1992, 3 % between 1992 and 2002, 11 % and between 2002 and 2014. cultivated land has decreased from 1.2ha to 1ha and from 2.2ha to 1.8ha in Kuhar Michael and Lenche Dima respectively, over the last 30years. This study aims to analyze the influence of various land use types on the water quality within the Chaohu Lake Basin based on the water quality monitoring data and RS data from 2000 to 2008, with the small watershed as the basic unit of analysis. 4.4 Environmental effects.
