A case study of New Asyut city
, Egyptian Journal of Remote Sensing and Space Science, 10.1016/j.ejrs.2018.03.006, 2019.04, The Egyptian government set out in the 1970s to establish new cities in the desert to absorb urban sprawl and to prevent further depletion of agricultural lands. Despite such efforts, this policy has not met with much success. In the present study, LANDSAT satellite imagery and binary logistic regression analysis were employed to investigate the nature of urban sprawl in one of the most important cities in Egypt, Asyut city, as well as the area connecting it to New Asyut city by quantifying the interaction between the driving forces of land use/cover change. Various socioeconomic factors associated with land control policy were examined. The results indicated that whereas directing urban development towards the new city created a semblance of balance initially, the rate of land development in the study area outstripped the rate of population growth, especially in the new city. While establishment of the new city boosted early urban development, further development in the regions outside the Nile valley was not sustained due to a lack of supportive governmental policies. Consequently, urban residents moved back inside the valley to re-settle on agricultural lands adjacent to the old urban cores. This study is the first to quantify the driving forces of land use in this region. It offers useful data to guide planned and purposeful expansion of urban land by government policy-makers in their effort to curb urban sprawl and prevent further encroachment on agricultural land in Egypt..
14. Divigalpitiya Upendra Chithra Sri Prasanna, K. Nurul Handayani, Measuring the urban expansion process of Yogyakarta City in Indonesia
Urban expansion process and spatial and temporal characteristics of growing cities
, International Review for Spatial Planning and Sustainable Development, 10.14246/irspsd.3.4_18, 2015.01, Urbanization patterns in rapidly growing cities are complex. Such patterns reflect historic policy outcomes, economic characteristics and changing lifestyles. This research examined urban growth in Yogyakarta City in Indonesia to understand its urban expansion process. Several attributes of urbanization were measured to understand the city's urbanization pattern. Land-use data for 1997, 2002, and 2013 were derived from remote-sensing data; in addition, other supporting data of urbanization were measured with several spatial metrics. Analysis was performed for the whole city and for transections across the city to understand macro and local scale characteristics of the urbanization process. Urban land-use changes between 2002 and 2013 were studied to understand the land-use conversion process. Thereafter, the measurements were analyzed to understand temporal and spatial characteristics of urbanization in Yogyakarta City. It was observed that the urban expansion process in Yogyakarta has several distinct stages. Essentially, in the periphery of the city, urbanization has been fragmented. Over time, these fragmented urban patches develop into stable and less complex shapes..

16. Divigalpitiya Upendra Chithra Sri Prasanna, Akira Ohgai, Takeru Tani, Kojiro Watanabe, Yoshimizu Gohnai, Modeling Land Conversion in the Colombo Metropolitan Area Using Cellular Automata, Journal of Asian Architecture and Building Engineering, 10.3130/jaabe.6.291, 2007.01, This paper proposes a Cellular Automata (CA) model to evaluate the urbanization patterns arising from the regulation of urban growth on paddy lands in the Colombo Metropolitan Region (CMR). Most of the historic map data available for the CMR before 1990 are temporally sporadic and spatially incomplete. As an alternative to maps, classified remote sensing data are used to analyze the urbanization process. Logistic regression is applied to derive factors of urbanization and the various relationships among them. The relation between ‘urban’ and ‘non-urban’ serves as an explanatory variable. The factors explaining that relationship are calculated by exploratory logistic regression analyses. The probability calculated from the statistical model is used for CA transition with a random number. Several growth patterns are simulated based on a range of transition thresholds to test the CA model. Status quo growth and several growth control scenarios are simulated for the period from 1987 to 2002 based on an optimum threshold. The simulation result of the status quo growth is evaluated with several evaluation methods. The level of agreement between the estimated result from the status quo model and the actual data is 62%, while the multi-scale goodness-of-fit method produces highly accurate values for the given range of resolutions..
