Measuring pattern and process of urban sprawl in South and Southeast Asian developing cities
2013.04～2017.04, 代表者：Prasanna Divigal, 人間環境学研究院, Japan Society for the Promotion of Science
南アジアや東南アジアの都市化率はいまだ低い状況にあるが、今後20年のうちに前例を見ないほどの都市人口の成長が見込まれている。すでに都市化が進行した都市を見ると、都市化と同時に経済成長を果たしており、都市化と経済成長の深い関係性は実証済みと言える。しかしながら、それらの都市のスプロール化に関する詳細については充分に理解されていない。近年、アジアの多くの国々では、地方分権化と経済の自由化を推進してきている。地方分権化を実現した都市では、土地の供給、雇用の創出、経済活動の変化が増進する傾向にあるが、これらの変化を見るには都市のスプロール化を検討することが有効である。そこで本研究では、南アジアと東南アジアにおいて都市スケールや都市ガバナンス・システムが異なる６都市を対象として、都市のスプロール化を定量的に分析することによって、都市のスプロール化とそのダイナミクスを明らかにすることを目的とする。.

It may be said that slums have become one with Caracas, and so to eradicate them completely would be almost impossible task. A more suitable solution therefore is to rehabilitate these areas, and improve the current living environment. Taking into account the meagre access to construction materials, the prevailing social conditions, and the absence of appropriate planning, we studied the potential of involving the inhabitants themselves through Participatory Development. After a detailed analysis of the current urban spaces, and following consultation of the local community, as well as professionals working in this field, we are able to generate lists of priorities based directly on the local inhabitants’ needs and desires, including: playgrounds; pathways; green areas; community centres; and other forms of small to medium-scale projects. This forms the basis for developing proposals to improve their community with their involvement and assistance. As was the case with urban projects such as ‘Espacios de Paz’ and ‘Inclusión de Habitantes’ (which included aspects of Slum Upgrading strategies and Participatory Design in slums of Venezuela), we conclude that shifting the methodology from slum eviction to slum upgrading fosters inclusion and respect for local heritage and culture, and creates a more sustainable and human-focused approach that aims to provide solutions to an on-going, deep-seated challenge..

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.

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..

The goal of this paper was to find an appropriate urban policy to preserve arable land that is being consumed by highly accelerated urban growth in the Giza Governorate of the Greater Cairo Metropolitan region for the last 50 years. We simulated three different urban policies and relevant growth scenarios for Giza from 2015 to 2035 by using the SLEUTH model to investigate their effects on arable lands. The first scenario used historical growth trends to simulate the persistent growth trends under existing conditions. The second was a compact growth scenario with robust restrictions on development in areas outside of designated growth centres. The third scenario considered officially planned growth that integrated stricter growth plans and stronger protections on lands with natural resources at a level that could be realistically accomplished with strong political commitments. The input data required by the model, including slope, land use, exclusion, and urban growth, transportation, and hill shade were derived from three Landsat satellite images from 1984, 2000, and 2013, according to supervised classifications. The simulation results found that the compact growth policy scenario had the least negative impact on arable lands, while the historical growth scenario had the worst impact..

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..

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..

Colombo, the largest city in Sri Lanka, has expanded rapidly and continuously since the local economy was opened in the early 1980s. As a contrast to the other cities in the region, one of the main issues that planners have observed with current urbanization pattern was the slow growth of population density in the region to sustain reasonable economic growth that can support modern transportation and other infrastructure. The new Western Region Megapolis Project (WRMP) is attempting to develop a cluster of urban centers connected with modern transportation network. According to the proposed development plan, a cluster of urban centers expected to create an urban development pattern with better territorial balance. The objective of the proposed strategy is increasing the current population base by stimulating migration to the region. The plan has an ambitious goal with an estimated population of 8.5 million by 2030 with 3 million increases. The strategies proposed in the WRMP to attract population to peripheral urban centers are improving connectivity and creating job opportunities by way of increased investments. This research demonstrates a methodology to evaluate urban planning scenarios arising from policies of in the WRMA proposal using CA model and a Latin Hypercube Sample design. This method is useful in situations where the availability of reliable socioeconomic data is not available for data-intensive simulations..

Since the 1950s, The Greater Cairo Metropolitan Region (GCMR) has witnessed an unprecedented rate of urban sprawl that has been mainly concentrated in arable lands against urban planning regulations, and has presented a critical challenge to the urban environment and serious corrosion for arable lands. Thus, the need to identify the driving factor of sprawl is crucial to understand the future of the GCMR urban environment and to overcome the serious challenges of rapid urbanization. We focused on the Giza governorate as a critical area in the GCMR and divided it into three sub-sectors to collect data and analyse. A primary list of driving factors was identified by literature review. Later this list was narrowed down to seven factors after interviews with local urban experts and consideration of the availability of data. Next, a logistic regression analysis was used to evaluate those factors with data derived from existing maps and remotely sensed data for the period of 2004–2013. An operating characteristic (ROC) evaluation of the logistic regression analysis gave high accuracy rates for the entire study area. The findings of the research revealed decreasing significance of the CBD and Nile River as drivers of sprawl. The most significant factors according to the analysis were neighbourhood factors, local urban centres, and accessibility factors of distances to urban uses and major roads. The research suggests more future urban expansion by the existing urban cores and along major roads, leading to more informal urban settlements. It also points to the possibility of persistent deterioration in the urban built environment and agricultural lands. Thus, these findings should be applied to actual urban planning policies, and development regulations should be strengthened to protect the urban environment from further deterioration..

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..

This research discusses housing policies changes and their effects on the housing issue in GCMR. Primary data were derived through questionnaire survey and secondary data from national censuses. The results find that the change in the general state policies did success in attracting more investments for public housing of low-income residents but failed to end the phenomenon of vacant housing or attract slums residents to new urban centers (NUC)..

The input data required by the model, including Slope, Land use, Exclusion, Urban growth, Transportation and Hillshade which were derived from three Landsat satellite images from 1984, 2000, and 2013 according to supervised classification. Three scenarios were designed to simulate the spatial pattern of urban growth. The first scenario is Historical growth trends to simulate the persisted growth trends by preserving the existing conditions. The second is a compact growth scenario with robust restrictions on development in areas that are outside of designated growth centers. The third scenario is growth as planned officially that integrates stricter growth plans and stronger protections on natural resource lands at a level that could be realistically accomplished with strong political obligation. Calibration of the SLEUTH model for Cairo metropolitan area manifested a high road coefficient beside similar high spread coefficient, which implies that the predicted mode of growth in Cairo are road influenced growth, and edge growth..

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..

LU-PST consists of an urban growth model and a land use zoning map support tool. The urban growth model is a Cellular Automata (CA) model, and population density by grid cell is calculated. The purpose of the land use zoning map support tool is to create zoning maps including residential, commercial, industrial and preservation zones. This tool used an AHP method in order to consider criterion for judgment of users. In order to develop the LU-PST, these two models were incorporated into ArcGIS (ESRI). It is possible for this tool to execute two tasks. One is for the land use zoning considered with urban growth trend. And the other is for the urban growth calculation based on a land use plan. The usefulness of LU-PST was discussed by analyzing the results of application to the Colombo Urban Area in Sri Lanka and considering comments about this tool from urban planners..
