Book excerpt: Master's Thesis from the year 2013 in the subject Geography / Earth Science - Cartography, Geographic Information Science and Geodesy, Sheffield Hallam University, language: English, abstract: This research examines the changes in land use/land cover in the city of Sulaymaniyah north of Iraq and identifies land surface temperature variations among the land cover types. The primary aim of this study is to use Landsat-5 TM imagery with GIS techniques to study and investigate the impact of urban expansion on land surface temperature (LST) for three year periods. Three Landsat 5 TM images were obtained in July 1984, August 2000 and October 2010. Land use categories were derived through the use of supervised classification techniques and the land surface temperature was obtained by computing the brightness temperature from the satellite sensor. The result showed that between 1984 and 2010, there was a mild decrease in open and barren lands from 69.3% in 1984 to 57.2% in 2010 while the built-up areas increased from 11.5% in 1984 to 15.5% in 2000 and reached 25.5% by 2010.The political and economic changes in the study area are the main factors behind the recent urban expansion. The lowest LST readings were taken from the vegetation lands with values of 28oC in 1984, 29oC in 2000 and 34oC in 2010. The barren lands recorded the highest temperature of 38oC, 38oC and 34oC for the years 1984, 2000 and 2010 respectively. An interesting observation in this study is the fact that the urban areas where found to be cooler than its surroundings zones. This is revealed by the LST analysis conducted, with the recent increase in green spaces in the city playing a major role in cooling the temperature there. In relating NDVI to LST, the study found a strong negative correlation between them having derived correlation values of the values of (-0.70), (-0.69) and (-0.73) for 1984, 2000 and 2010 respectively. Conclusively, remote sensing and GIS proved to be very effective in studying and monitoring the relationship between urban growth and surface temperature. Recommendations were made to encourage the expansion of urban surfaces into the surrounding areas, especially barren lands, in order to cool those areas.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the findings of a three-year study on urban heat in Doha, Qatar, and discusses guidelines and strategies for planning agencies to consider in the context of moderating temperatures to provide pedestrians with greater access to outdoor spaces and greater choice in modes of transport. If modifying urban form can reduce extreme temperatures in one of the hottest places on the planet, then perhaps other communities can learn how to create livable cities during a time of rapid changes to the climate. In fact, despite the periods of extreme heat, strategic planning and management of urban areas can improve residents’ and visitors’ ability to live, work, and move throughout the city comfortably. Doha, Qatar, a city with one of the most extreme climates on earth, has undergone rapid development over the past 40 years. Although cities in the Middle East are expanding at three times the international average (UN Report, 2012), the rapid population and physical growth remain largely unexamined, particularly in terms of the unique conditions, qualities, and characteristics that give rise to these emerging centres. Speed, quality, and extent of urbanization impact neighbourhood-scale environmental conditions, and this book provides evidence that urban forms and materials can help to mediate temporal variation in microclimates and that landscape modifications can potentially reduce temperatures and increase accessibility to outdoor environments. By applying the lessons in this book, communities around the world can better adapt to the increasing frequency, duration and intensity of extreme heat.

Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2011 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, grade: A, Swedish University of Agricultural Sciences (Department of Aquatic Sciences and Assessment), language: English, abstract: This report investigates the relationship between the degree of imperviousness - surface sealing - and the water balance - surface runoff, evapotranspiration and infiltration. It synthesizes case studies for the cities Leipzig, Dessau and Munich in Germany and the Grote-Nete catchment in Belgium and compares the effect of different urban land uses on the water balance. The annual precipitation ranges from 530 to 950 mm. Depending on the respective hydrological properties and land use characteristics a linear increase of surface runoff with increasing degree of imperviousness could be found for all of the German studies. Evapotranspiration and infiltration decline with an increasing degree of imperviousness. The relationship for both is not distinct as for surface runoff. The impact on the water balance does not significantly deviate for different levels of precipitation.

Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2019 in the subject Geography / Earth Science - Regional Geography, University of Gondar, course: Development studies, language: English, abstract: This study is intended to assess the impacts of urban expansion on farm land of the surrounding rural kebeles of Tefki town from the year 2012-2016. Urbanization is recently a rising trend seen all over the world, mostly in an upsetting rate in developing countries. Similarly, most towns in Ethiopia are recently becoming expanded towards the adjacent farm land. The Expansions of these towns were resulted in the conversion of farm land to urban land uses. Specifically, the study focused on evaluating the effects of town expansion on the farmers (households) in terms of land loss and income, the opportunities of the affected households secured from the town expansion and compensation process. Hence, 166 expansion affected households were selected through snowball sampling, and also 5 officials from different institutions were purposively taken. Thus, the primary data were collected using questionnaires and interview. Secondary data have been also used to triangulate and supplement the first hand information. The collected data were analyzed by using SPSS version 20. The result showed that Tefki town rapidly expanded during the last five years as a result of population growth and industrialization. This expansion made significant effects on farm lands of the surrounding farmers. Although they secured access to certain services, it was also brought effects like loss of agricultural land and other assets including grazing land, and unfair compensation. This expansion has made the households of the surrounding area to lose farm land on which their livelihood used to depend on for long period of time. Every farmer has been made to lose an average of 1 hectare of their owned farm land. The grazing land of the area has been decreased because of town expansion, and thus made farmers to lack enough place of grazing for their livestock. On the other side, the compensation was not made on time for the affected farmers. The study also found out that the compensation given to the farmers was not fair, and too inadequate to sustain the livelihoods of the affected households. Therefore, a detailed potential effect assessment study should be carried out by the government and other stakeholders prior to implementing urbanization programs so as to minimize the adverse effects of urban

This book was released on 2019-07-16 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2019 in the subject Engineering - General, Basics, grade: Excellent, , course: Raod and Transport Engineering, language: English, abstract: Marshall Mix design was developed for the hottest pavement surface temperature of the USA, which is 60-degree Celsius. This design mechanism is very dominant in our country. It was directly adopted without any modification. The research aims to develop a prediction model that will be employed to modify the Marshall Mix design method for the Ethiopian climate and incorporate maximum pavement surface temperature. In order to do so, ten years historical air temperature of Ethiopia, taken from the National Metrology Agency which was used to determine the hottest month for onsite measurement of 24 towns. For each town, actual maximum pavement surface temperature was measured from August 2016- February 2018, using Nanosensor/ radiator thermometer. The countries climate was classified into four climatic regions for the purpose of this research. For each region, a representative town is incorporated on the study. Based on site measurement and maximum air temperature with the associated latitude, Multivariate Regression Model was selected. To select the model R-squared value method, an excel analysis of scatter plots and collinearity of the explanatory variables was checked. All the inputs were provided to STATA SE-13 statistical software and model developed. After the model was developed by all the 24 towns' data, it was validated and cross-validated by dividing the data into 5 folds in order to make it applicable for all scenarios. The model was further elaborated in a laboratory case study, for the hottest town of Samara, Afar region capital. Mix design was prepared at 60°C, which is the standard specimen heating temperature and at 75°C, which is the actual maximum pavement surface temperature of Samara town. The mix that was prepared at 60° C, found to fulfill all the criteria's of Marshall Mix design outlined by Asphalt Institute for heavy Traffics. Whereas, at 75°C, it fails to do so. Therefore, mix design should be conducted at the place maximum pavement surface Temperature rather than conducting at the standard 60degree Celsius.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific Essay from the year 2021 in the subject Physics - Applied physics, grade: A, The Technical University of Kenya, language: English, abstract: After learning the refractive index concept in class, the author started wondering what will be the effect of changing temperature on the refractive index. Being a fan of swimming, concepts of apparent and real depth have always been fascinating to me. In this paper, he wanted to explore how the apparent and real depth of a liquid would change with an increase in temperature at different times of the day. The speed of light keeps changing as light moves from one medium to another of different optical densities. For instance, the speed of a ray of light moving from a denser medium to a rarer medium will decrease. If the ray reverse in the same direction, this time moving from a rarer medium to a denser medium, its speed will increase. Ideally, when the ray moves from a denser medium to a rarer medium, its particles collect together, hence reducing speed. On the other hand, when the ray is moving from the rarer medium to a denser medium, its particles spread out, and speed increases.

Download or read book The Urban Heat Island written by Iain D. Stewart and published by Elsevier. This book was released on 2021-05-25 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Urban Heat Island (UHI) is an area of growing interest for many people studying the urban environment and local/global climate change. The UHI has been scientifically studied for 200 years and, although it is an apparently simple phenomenon, there is considerable confusion around the different types of UHI and their assessment. The Urban Heat Island—A Guidebook provides simple instructions for measuring and analysing the phenomenon, as well as greater context for defining the UHI and the impacts it can have. Readers will be empowered to work within a set of guidelines that enable direct comparison of UHI effects across diverse settings, while informing a wide range of climate mitigation and adaptation programs to modify human behaviour and the built form. This opens the door to true global assessments of local climate change in cities. Urban planning and design strategies can then be evaluated for their effectiveness at mitigating these changes. Covers both on-surface and near-surface, or canopy, measurements and impacts of Urban Heat Islands (UHI) Provides a set of best practices and guidelines for UHI observation and analysis Includes both conceptual overviews and practical instructions for a wide range of uses

Download or read book Urbanization and Growth written by Michael Spence and published by World Bank Publications. This book was released on 2008-11-26 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why is productivity higher in cities? Does urbanization cause growth or does growth cause urbanization? Do countries achieve rapid growth or high incomes without urbanization? How can policy makers reap the benefits of urbanization without paying too high a cost? Does supporting urbanization imply neglecting rural areas? Why do so few governments welcome urbanization? What should governments do to improve housing conditions in cities as they urbanize? Are innovations in housing finance a blessing or a curse for developing countries? How will governments finance the trillions of dollars of infrastructure spending needed for cities in developing countries? First in a series of thematic volumes, this book was prepared for the Commission on Growth and Development to evaluate the state of knowledge of the relationship between urbanization and economic growth. It does not pretend to provide all the answers, but it does identify insights and policy levers to help countries make urbanization work as part of a national growth strategy. It examines a variety of topics: the relevance and policy implications of recent advances in urban economics for developing countries, the role of economic geography in global economic trends and trade patterns, the impacts of urbanization on spatial inequality within countries, and alternative approaches to financing the substantial infrastructure investments required in developing-country cities. Written by prominent academics in their fields, Urbanization and Growth seeks to create a better understanding of the role of urbanization in growth and to inform policy makers tackling the formidable challenges it poses.

This book was released on 2006 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper clearly shows the immediate relevancy of historical study to current events. One of the most common criticisms of the U.S. plan to invade Iraq in 2003 is that too few troops were used. The argument often fails to satisfy anyone for there is no standard against which to judge. A figure of 20 troops per 1000 of the local population is often mentioned as the standard, but as McGrath shows, that figure was arrived at with some questionable assumptions. By analyzing seven military operations from the last 100 years, he arrives at an average number of military forces per 1000 of the population that have been employed in what would generally be considered successful military campaigns. He also points out a variety of important factors affecting those numbers-from geography to local forces employed to supplement soldiers on the battlefield, to the use of contractors-among others.

Download or read book The Mobility of Displaced Syrians written by World Bank and published by World Bank Publications. This book was released on 2020-01-27 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The war in Syria, now in its eighth year, continues to take its toll on the Syrian people. More than half of the population of Syria remains displaced; 5.6 million persons are registered as refugees outside of the country and another 6.2 million are displaced within Syria's borders. The internally displaced persons include 2 million school-age children; of these, less than half attend school. Another 739,000 Syrian children are out of school in the five neighborhood countries that host Syria's refugees. The loss of human capital is staggering, and it will create permanent hardships for generations of Syrians going forward. Despite the tragic prospects for renewed fighting in certain parts of the country, an overall reduction in armed conflict is possible going forward. However, international experience shows that the absence of fighting is rarely a singular trigger for the return of displaced people. Numerous other factors—including improved security and socioeconomic conditions in origin states, access to property and assets, the availability of key services, and restitution in home areas—play important roles in shaping the scale and composition of the returns. Overall, refugees have their own calculus of return that considers all of these factors and assesses available options. The Mobility of Displaced Syrians: An Economic and Social Analysis sheds light on the 'mobility calculus' of Syrian refugees. While dismissing any policies that imply wrongful practices involving forced repatriation, the study analyzes factors that may be considered by refugees in their own decisions to relocate. It provides a conceptual framework, supported by data and analysis, to facilitate an impartial conversation about refugees and their mobility choices. It also explores the diversified policy toolkit that the international community has available—and the most effective ways in which the toolkit can be adapted—to maximize the well-being of refugees, host countries, and the people in Syria.
