Urban growth is a worldwide phenomenon but the rate of urbanization is very fast in developing country like Egypt. It is mainly driven by unorganized expansion, increased immigration, rapidly increasing population. In this context, land use and land cover change are considered one of the central components in current strategies for managing natural resources and monitoring environmental changes. In Egypt, urban growth has brought serious losses of agricultural land and water bodies. Urban growth is responsible for a variety of urban environmental issues like decreased air quality, increased runoff and subsequent flooding, increased local temperature, deterioration of water quality, etc. Egypt possessed a number of fast growing cities. Mansoura and Talkha cities in Daqahlia governorate are expanding rapidly with varying growth rates and patterns. In this context, geospatial technologies and remote sensing methodology provide essential tools which can be applied in the analysis of land use change detection. This paper is an attempt to assess the land use change detection by using GIS in Mansoura and Talkha from 1985 to 2010. Change detection analysis shows that built-up area has been increased from 28 to 255km2 by more than 30% and agricultural land reduced by 33%. Future prediction is done by using the Markov chain analysis. Information on urban growth, land use and land cover change study is very useful to local government and urban planners for the betterment of future plans of sustainable development of the city

At present, the environmental quality of urban regions and outdoor spaces has turn out to be one of the main issues facing both climatologists and designers, which could be identified through their research outcomes. It is argued that the urban configuration affects the micro-climate of the urban outdoor spaces. The street’s orientation form was identified as an element, which impacts the urban environment with regards of receiving passive solar, solar radiation and reflection against urban absorption, wind flow and the possible urban cooling techniques. The key purpose of this study is to look into the urban configuration factors affecting the human thermal outdoor comfort in Jeddah city as an example of hot humid climate regions. To accomplish its aim, the research is divided to two sections. The first one illustrates the problem of the research, then generally reviews the literature associated with the outdoor human thermal comfort; in addition, it discusses the relationship between street orientation and micro-climate. The second section highlight the assessments carried out between four different orientations of urban streets from two different districts in Jeddah city, using ENVI-met software. The research adopts three environmental variables to be examined, namely air temperature, wind speed, relative humidity together with pedestrian thermal comfort as indicators for predicted mean vote, during summer and winter seasons. The outcomes of the comparison assist to identify decisions related street networks to achieve the desirable human outdoor thermal comfort in such an urban environment.

In developing countries, most cities suffer from numerous problems associated with the processes of their urban management and development. These problems have a great influence on the environmental performance of those cities. Egyptian cities are no exception to such cities. Recently, Egypt has been undergoing rapid urbanization and industrialization. It is claimed that there have been various undesired effects on the environment resulting from these development processes. In fact, it could be said that development processes, as a result of national policy over the past 3 decades, are associated with a wide range of problems and impacts on the environment. In this respect, sustainability has been the most trending issue in developing urban communities all over the world. Great efforts have been made through sustainable urban design to enhance the quality of life. Furthermore, it is advocated that to make these communities sustainable, a comprehensive management of their systems is essential. This research advocates that green mechanisms within urban management in Egypt would offer appropriate solutions for their problems. This research casts light on one of the recent green urban management evaluation mechanisms. The African Green City Index is adopted in this research to examine the environmental performance of three new cities in Egypt, and the commitment made to reducing the environmental impact associated with their urban development. The research concludes with the identification of green policy proposals for improving the selected cities’ environmental performance and urban management. These proposals could be considered as initiatives and guidelines for other Egyptian cities and could pave the way for identifying appropriate policies for enhancing the quality of green city urban systems within the Egyptian context.

Egypt adapted many experiments by establishment of new towns and urban settlements in the desert areas. These experiments aim to achieve developmental strategic aspects in the fields of urbanization, environmental, economic, and social. However, there is severe limitation in the achievement of the requirement rates either in the demographic growth rates, or in the economic growth rates, or in the urban development rates. Therefore, it should be evaluated either from the theoretical aspect or the executive one. Thus, the aim of this paper is to investigate Egypt’s new town policy, a central pillar of the nation’s urban development strategy over the last 30years. The history and growth of new towns are reviewed; challenges as well as achievements are identified. Sixth of October new town is chosen as a case study, to delve into the details of development issues in one of the largest new towns. Finally, policy implications for improving the performance of Sixth of October and other new towns are suggested

Biogeometry is the patented science of using the energy of shapes and forms to qualitatively make a balance between the biological energy systems and accommodate their interactions with the environment. Balancing the activities of daily life, attaining harmony with our environment, humanizing modern technology, and incorporating science and spirituality are the work of the science of biogeometry. The research in biogeometry was and still is mainly dedicated to the development of a new form of architecture that would improve the human biological system. In this context, the current study aims to develop a scientific approach to investigate the influence of the geometric forms and construction materials of the architectural spaces on the users’ brainwaves and then on their consciousness status which is considered as the main controlling factor in human bioenergy. Trying to consolidating the theoretical views of this effect to be measurable scientifically, the study is based on using a numerical analysis based on a computerized simulation. The results of this study show different influences based on geometric forms and construction materials. The study is carried out using CST Microwave Studio to identify the resonance frequency occurred inside different geometric forms with different construction materials, and then distinguish the related user’s brainwaves which influence his/her consciousness status. This may assist architects and designers in identifying appropriate geometric forms to suit the required uses and functions that need particular consciousness statuses.

In Saudi Arabia, an array of diverse strategies has been applied in response to the adverse effects of urban sprawl. A review of the historical proliferation of these strategies indicates that although in the short term the strategies have achieved high-quality infrastructure in some parts of the major cities, longer-term prospects are less promising since numerous urban problems persist in these cities. Among these problems are uncontrolled developments in the fringes, inadequate urban services, spiralling land prices and construction costs, the proliferation of slums and degrading quality of the urban environment. This research focuses on urban growth management as an approach for sustainable communities. The study will then discuss urban growth management as a discipline that can empower Jeddah as one of the fastest Saudi major cities to generate better urban development strategies and policies for a new generation of communities. This research paper explores ways to manage Jeddah’s urban growth and new development. The objective is to generate new communities that offer higher standards of living while meeting the challenge inside the existing urban mass by providing the much-needed new policies to limit and control urban growth. It is, therefore, an absolute must begin revising our urban growth and spatial development policies and plans. New theories of urban growth, development and management must be carefully examined and studied, and solutions must be devised, sooner than later, to help promote achieving sustainable urban management in Saudi Arabia.
