Muhammad Salem, Naoki Tsurusaki, Prasanna Divigalpitiya, Land use/land cover change detection and urban sprawl in the peri-urban area of greater Cairo since the Egyptian revolution of 2011, JOURNAL OF LAND USE SCIENCE, 10.1080/1747423X.2020.1765425, 15, 5, 592-606, 2020.09, Land use/land cover (LULC) has changed dramatically in the peri-urban area (PUA) of greater Cairo (GC) since the Egyptian revolution of 2011. This study analyzes LULC change in the PUA of GC using two Landsat images from 2010 and 2018. The spatial trends of LULC change and visualizations of the gains and losses in LULC were analyzed using TerrSet software. The driving forces of LULC change from 2010-2018 were quantified using the logistic regression model (LRM). The results revealed that the processes of LULC change and urban sprawl have directly impacted the natural resources, particularly agricultural land. In addition, the study showed that the population growth and land value have the highest regression coefficients, 0.660 and 0.292, respectively, and were the most significant driving forces of LULC from 2010-2018. The outcomes of this study are important for decision-makers to adopt appropriate strategies for sustainable land use in this area..
7. The Trend and Actual Condition of Small-Size Residence of Single-Person Households around the University Campuses in Seoul
This study aims to identify measures to improve the living environment of Single-person households and university students in areas around the campus by examining the present conditions and efforts taken by the universities where the campus plan is carried out. The small-scale housing where single-person households and University students could live are quasi dwellings, dormitory, and Urban-life-housing according to the analysis based on the law and planning survey, the field survey and the hearing survey. Governments and universities have built dormitories to supply student housing. But it was difficult due to the opposition from the local residents. Small-scale housing for single-person households are located in mixed-use residential areas with commercial and business facilities, and they lack parking lots and the buildings are deteriorating. In order to improve the living environment of the single-person households in the surrounding area if university campuses; improving the pedestrian safety, living environment improvements, promotion of mixed use of the building, efforts for connection, and cooperation is necessary..

Hatem Mahmoud, Prasanna Divigalpitiya, Spatiotemporal variation analysis of urban land expansion in the establishment of new communities in Upper Egypt: A case study of New Asyut city, EGYPTIAN JOURNAL OF REMOTE SENSING AND SPACE SCIENCES, 10.1016/j.ejrs.2018.03.006, 22, 1, 59-66, 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.

Maharjan Sarita, Tsurusaki Naoki, Divigalpitiya Prasanna, The Influence of Urban Form on Travel Energy Consumption in Kathmandu, Proceedings of International Exchange and Innovation Conference on Engineering & Sciences (IEICES), 10.15017/1961294, 4, 90-95, 2018.10, A rapid increase in travel energy consumption is becoming serious issues in Kathmandu, Nepal. This study examined the effect of urban form; 5Ds (density, diversity, design, destination accessibility and distance to transit) on the travel energy consumption. First, empirical analysis is performed based on 5Ds to understand the urban form of entire Kathmandu via 35wards. Afterward, homogenous groups are identified based on 5Ds and travel energy consumption by using k-means cluster analysis. The result highlights: (1) Compact planning in Kathmandu indicates the highest walking mode share, however among the energy-intensive mode, motorcycle is found highly used, (2) Residential area has direct effect on travel energy consumption, (3) Higher travel energy consumption is found due to maximum motorcycle use in highly road connected areas (D3) which are far from Central Business District (CBD) and longer travel distance as the effect of less density (D1), low land use mix (D2) and poor transit accessibility (D5)..

Sprawl patterns in the study area were influenced by seven driving forces: geographical characteristics, availability of life facilities, economic incentives, land demand and supply, population increases, administrative functions, and development plans. These forces have varying degrees of influence in each sector. Amongst these forces, economic incentives in the middle sector, population increases in the north sector, and administrative functions in the south sector were the forces most influential in urban sprawl.

11. Taher Osman, Takafumi Arima, Prasanna Divigalpitiya, Measuring Urban Sprawl Patterns in Greater Cairo Metropolitan Region, JOURNAL OF THE INDIAN SOCIETY OF REMOTE SENSING, 10.1007/s12524-015-0489-6, 44, 2, 287-295, 2016.04, On the subject of informal sprawl in recent Egypt, this research takes Greater Cairo Region (GCR) as a case and puts forward that informal urban sprawl can be estimated from spatial disposition, informal sprawl efficacy and outer influences; and then evolves a geo-spatial indicators system for quantifying sprawl. So as to estimating these indicators, various data sources are selected, including land use maps, digitized map of the highways and town centers, and population statistical data, etc. GIS spatial analysis methods are used to spatialize these indicators into 120 m x 120 m cells. In addition, an incorporated sprawl index (ISI) is estimated by weight sum of these indicators. The results demonstrated that geo-spatial indicators system can captivate most of the exemplary attributes and interior differentia of urban sprawl. Building land in Cairo has kept quick growing with considerable amount of low efficacy and dysfunctional spatial disposition. The subsequent sprawl attributes are determined by each indicator's exemplary spatial disposition of urban sprawling, conspicuous fragmentation and unevenness of landscape due to ineffective implementation of land use planning, improper pattern of exemplary discontinuous development, strip development and leapfrog development, low efficacy of sprawl, low development density, low population density output in newly developed areas; and unfavorable influences on agriculture and environment and population life..
12. Taher Osman, Prasanna Divigalpitiya, Takafumi Arima, Quantifying the Driving Forces of Informal Urbanization in the Western Part of the Greater Cairo Metropolitan Region, ENVIRONMENTS, 10.3390/environments3020013, 3, 2, 1-17, 2016.06, This paper discusses the driving forces (DFs) of informal urbanization (IU) in the greater Cairo metropolitan region (GCMR) using the Analytic Hierarchy Process (AHP). The IU patterns in the GCMR have been extremely influenced by seven DFs: geographical characteristics, availability of life facilities, economic incentives, land demand and supply, population increase, administrative function, and development plans. This research found that these forces vary significantly in how they influence urban growth in the three study sectors, namely, the middle, north, and south areas in the western part of the GCMR. The forces with the highest influence were economic incentives in the middle sector, population increase in the north sector, and the administrative function in the south sector. Due to the lower availability of buildable land in the middle sector, the land demand and supply force had a lesser influence in this sector compared to in the north and south sectors. The development plans force had medium influence in all sectors. The geographical characteristics force had little influence in both the middle and the north sectors, but higher influence than economic incentives, availability of life facilities, and development plans in the south sector. Because of the spatial variances in life facilities organizations in the GCMR, the life facilities availability force had little effect on IU in the south sector..

In this respect, the authors examined the effect of urban characteristics of unplanned settlements on SD in the Egyptian context, focusing on the type of unplanned growth on agricultural land. The output of the analysis were fourfold. First of all, we provide a brief overview of previous research on the main types of unplanned settlements in GCMR and the sustainability definition according to the Egyptian context. Secondly, we had a discussion with the local government during our field survey in GCMR to determine the study samples, the main urban characteristics, and the sustainability evaluation criteria in the Egyptian context. Thirdly, through the comparative analysis and geographic information system (GIS), we examined how the character of urban development affected per capita four urban measures in a cross-section of two settlements, one represented the unplanned settlements and other as a comparative planned sample to determine the real gap. Finally, by using the evaluation matrix, the help and block items are estimated for each measure of urban characteristics, providing substantive evidence on how the four measures of urban characteristics have been affected by the urban sprawl..

Osman, The impact of Built Environment Characteristics on Metropolitans Energy Consumption: An Example of Greater Cairo Metropolitan Region, BUILDINGS, 10.3390/buildings6020012, 6, 2, 2016.06, This paper examined the influences of the built environment and socio-economic driving factors on domestic gasoline consumption in developing metropolitan regions through a case study of the greater Cairo metropolitan region (GCMR), Egypt. Structural equation modeling (SEM) was used in analyzing the causality of the domestic gasoline consumption. The influences of major factors hypothetically affecting the domestic energy consumption such as resident characteristics and built environment characteristics were examined. The results proved a high positive influence of the resident's income and the number of adults as driving factors, directly and indirectly, affecting energy consumption levels. Population density and attitude towards eco-friendly driving factors proved to be a very low influence on energy consumption. The built environment driving factors such as access time to public transportation and related building characteristics factors proved to have a low impact on energy consumption. The study findings suggest that the design of a built environment should be well related to the socioeconomic factors to manage the domestic energy consumption in developing regions..
