Intense human activities and drastic land use changes in rapidly urbanized areas may cause serious water quality degradation. Positive effects of Urbanization: • Despite the above disadvantages of urbanization, we must also remain thankful for its benefits. Most of the soil is lost through the surface runoff. This makes cities more susceptible to natural disasters like the Tsunami. Desertification in the West Sahel 4.3. and local land markets. The implications of rapid urban growth include increasing unemployment, environmental degradation, lack of urban services, overburdening of existing infrastructure . Let us find out what surface runoff means. Land degradation, deforestation and climate risks contribute to the country's economic vulnerabilities and poverty, according to the report. The impacts may be negative or positive. Forest degradation in the Amazon has facilitated the spread of diseases with potentially large social and economic impacts, both locally and globally. (Bogart and Richardson 2009) 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). Expansion of agricultural production, fuelled by population growth and demand from the city, threatens widespread soil erosion, land degradation and groundwater pollution. Significant changes in the chloride concentration are also observed in two areas: increasing from 100 mg/l to 1,600 mg/l and from 2,000 mg/l to 4,000 mg/l, respectively. Loss of Biodiversity. Increasing levels of urbanization are caused by natural growth of the urban population and migration of the rural population towards cities. 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. Biodiversity 4. Deforestation is the logging and/or burning of trees in a forested area [9]. 3. 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. 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]. Degradation of Wetland (WTL) Ecosystems I. Definitions A. USF&WS: Lands transitional between terrestrial & aquatic: Lands transitional between terrestrial & aquatic systems where the H 2 O table @ or near ground surface. 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. 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. 2. Measuring the migration effects of land degradation 22 6.1 Measuring and mapping land degradation at global and regional scales 23 Land degradation occurs slowly and cumulatively and has long lasting impacts on rural people who become increasing vulnerable (Muchena 2008). 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. The causes of land degradation can be divided into natural hazards, direct causes, and underlying causes. 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 … 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. Hence, in order to sustain economic growth there is a high demand on already scarce natural resources. By 2050, 68% of the world population is projected to live in urban areas. "Urbanization and the Natural Drainage System-Impacts, Solutions, and Prognosis." From the point of view of environmental accounting, land, water, and air are treated as assets that areused in the production of 3 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. The promise of jobs and prosperity, among other factors, pulls people to cities. 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. The resources which are affected include water, air and soil. Land degradation affects the earth’s productivity. Urbanization is attractive to many rural citizens for the many opportunities it creates in bettering their quality of life. 4 Booth, Derek B. Land reclamation, which uses coastal land for urban use, is leading to a decrease in coastal forests like mangroves. 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. many parts of the world. Impact # 1. 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. However, many elements of urbanization can turn burdensome for a city and its citizens if it is not planned for carefully. Effects of war. Water Resources Research, 11, 431-5 6 Chester L.
