The process has had a major impact on many urban landscapes, and has played an important role in the history and demographics of cities around the world. The purpose of urban renewal is to improve specific areas of a city that are poorly developed or underdeveloped. These areas
3. Pollution Prone to increased air pollution due to the concentration of infrastructure in the area which have serious repercussions on the environment. Section 2 (25%) Pick: ONE CONTINENT FROM THE GLOBAL NORTH (Choose Europe OR Northern America OR Oceania) and ONE CONTINENT FROM THE GLOBAL SOUTH (Choose Asia OR Africa OR Latin America and the Caribbean) For the Global North continent: What is the trend with regards to urban population and city
Such changes have affected mainly on the individual and society but in different ways  and the phenomenon of cities growth is steadily increase, so the urban population growth rate exceeds the population growth rate . Herper and Gottman defined the urban sprawl process by spread and extension out the border of the city, e.g. the urban sprawl without adhering to the limits of the areas where this process has occurred . The urban sprawl is known as continuing increase in the numbers of the population, whether in regular or irregular housing, which increases the demand on agricultural land, then creates defect in the ecological balance . Several studies indicate that urbanization in cities of developing countries is happening in a quantitative manner rather than quality; e.g.
AQI helps government agencies to take preventive measures and steps to control the pollution level. Artificial neural network (ANN) is a computational model based on the structure and functions of the biological neuron and can be used for prediction after proper training is given to the network Keywords—pollution, AQI, Artifical Neural Network I. Introduction India is a developing country and with this era of industrialization most cities are suffering from serious air quality problems.  Along with industrialization, rapid growth in population is also a major cause for increasing air pollutionAir pollutants, such as carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), ozone (O3), heavy metals, and respirable particulate matter (PM2.5 and PM10), differ in their chemical composition, reaction properties,
Urbanisation is the shift from rural to urban moving massive amounts of people into large cities, something that is happening quickly in the world right now. By becoming more urban, the world has changed forever for the better and the worst. Many different phenomenon and events both caused urbanisation or are a result of urbanisation. There are both negative and positive effects of urbanisation and they also play an important role in our lives. Urbanisation is happening in our life time and their causes and effects also impact us.
Generally, its relevance is referred to two aspects or issues in urban and fringe area perspectives: (a) contribution of internal migration on urban growth as well as the pace level of urbanization (Pacione, 2001), and (b) negative implications of internal migration on urban areas such as urban sprawl, squatters and slum areas, poverty, and pollution (Skeldon, 2002, Yaakup et al., 2000). Rashid and Ghani (2011) also incorporate to control of high volume of migration to understanding spatial trends and distribution of migration. As spatial trends and distribution of migration is a crucial for the purpose of urban planning decision making. So the proper growth of seasonal migration is essential as it has both positive and contradict impact on society. Beside my research will provide an overall pattern of migration that may contribute to spatial trends and distribution of migration
The air pollution path of the urban atmosphere consists of emission and transmission of air pollutants resulting in the ambient air pollution (Mayer, 1999). Cities and urban corridors are sites of intense human activity, and many of these activities contribute to air pollution. According to Botkin & Keller (2014), pollutants emitted into the atmosphere at a particular site may join the global circulation pattern and spread throughout the world, and pollutants emitted from urban or agricultural areas may be dispersed to pristine areas far removed from human activities. Urban air pollution, like water pollution and environmental problems associated with solid waste is caused by inability of the local environment to accommodate the level of waste produced by large numbers of people concentrated in relatively small areas. Sources of urban air pollution maybe grouped according to their origin in industrial, residential and transport activities
When the city development, urban heat island, effect becomes more and more severe. Urban Heart Island means that refers to the city due to a large number of artificial fever, buildings and roads and other high-heat storage and green space reduction and other factors, resulting in the city "high temperature". Cities are the most obvious places where the global environmental change and health problems cross each other. The available evidence confirms that global climate change is leading to more and more intense extreme heat / cold events. Interactions between extreme hot / cold events and pollution lead to increased morbidity and mortality in urban-susceptible populations.
The contemporary world is an urban world. This is apparent in the expansion of urban areas and the extension of urban influences across much of the habitable surface of the planet. Today, for the first time in the history of humankind, urban dwellers outnumber rural residents. Urban places – towns and cities – are of fundamental importance: for the distribution of population within countries; in the organization of economic production, distribution and exchange; in the structuring of social reproduction and cultural life; and in the allocation and exercise of power. Furthermore, in the course of the present century the number of urban dwellers and level of global urbanization are likely to increase.
Geographers describe urbanization as “the increase in the proportion of people living in towns and cities.”1 On the other hand Sociologists define urbanization as “the societal trend where the proportion of people living in cities increases while the proportion of people living in the countryside diminishes.”2 UNESCO defines urbanization as “the proportion of a country that is urban”.3 According to the UN “in the brink of entering the modern era , the world’s major settlements have seen immense growth in population and infrastructure”. 4 This research will seek to establish if the changes that have taken place in Maldives conform to the above given definitions and provide insights into the negative as well as positive aspects of urbanization. The different effects of urbanization such as financial, socio - cultural and environmental effects will be taken into account in this research. l also intend to establish whether urbanization has brought more harm or good
