Abstract

A rapid urbanization has resulted in more rush transformation of a settlement of low-income migration growth into an urban area. The growt squatter settlement role was influenced through an urban form conflict. Many of these points have been debated over the issue of sustainable urban development plan that has led the way into the urban building density appearance and the phenomenon of its urban area growth effects. The ultimate results depend on an increase in carbon emissions changed over time and its effect on climate change. The real challenged problems are being solved in the developing country, such as Thailand's capital Bangkok. Moreover, an unplanned and low-efficient development projects cause extensive devastating consequences to both urban environment and human beings. Particularly for the low-income people who live in a lowland area are more heavily buderned by environmental risks and unsafe area. Thus, it is imperative for this paper to discover a key issue of low-income migration and settlement on the basis of the measurements which includes: (a) the situation of urbanization driving process forces the low-income settlement growth, and (b) investigate the causes and effects on urbanization in terms of the urban environmental conditions and locations system (e.g. sensitivity analysis, risk approaches) using GIS-based Multi-Criteria Decision Analysis (MCA) for calculating the simplify situations of the alternative factors and using the Analytical Hierarchy Process (AHP) for weighting the measure of individual participant data. By this approach, it is becoming more feasible to be configured, with the Weighted Linear Combination (WLC) operators. This tool presents the usefulness of the relative important weights for relevant approaches of low-income settlement in consequences of growing cities based on geographic information system (GIS).

Abstract

Public parks are one of the representatives of urban environment that play an essential role to daily life of people and provide a variety of benefits and opportunities for community as green spaces. The lack of understanding of associations between pattern of park utilization and users’ preference has made difficulties to highlight the role of public parks in community while reflecting social needs of park users. To reflect actual preference of park users, Saga city in Japan was selected as a case study by employ an unconventional method to capture the real preference from actual target group of public park service. An indirect value of park users’ benefits estimation has been done through the determination of preference value factor, PVF in different users’ socioeconomic and recreation activity characteristics. The uniqueness of this method is to focus on the linkages between the availability of public parks and social preferences. On the basis of findings, the results pointed out that not only different satisfaction on park service induce on the differentiation of PVF value but the different willingness to pay on maintenance and management park service also result to demonstrates an different intuitive appreciation for environmental valuation based on park visitors’ preference.

Abstract

Public parks provide a numerous benefits and opportunities for community and however, to maintenance of public parks need large amount of local governmental budget. This study investigates park users’ preference on willingness to pay to quantify recreational benefit of public parks. A new assessment method was proposed to verify the consistency of data collection by utilizing the relatively simply technique, we called string method. Based on this approach, a case study of three public parks in Saga city, Japan was established to qualify users’ view that could enable us to evaluate their participation on the improvement of accessibility and attractiveness of park according to community needs. The result indicated that different patterns of recreational travel and activity on park visitation induce in different compensation on public activities’ program. This useful information could be utilized to guide local planning agency to locate suitable policy for public park service improvement.

Abstract

Recently, there are a number of disaster occurred in several regions worldwide which might be caused of climate change effects. This damage alarmed many researchers to determine the possibility and risk. Bangkok Metropolitan Region (BMR) is low land area which is potentially flooding risk caused by river flood, flash floods and tropical storm in each year. Evacuation approach is necessary to response in disaster event, especially in low lying areas from the potential life-threatening effects of hazards to safe inland. According to study the local people’s perceptions of storm surge in Amphoe Mueng, Samut Prakarn, the result was shown that most samples evacuate to outside Samut Parakarn area by their own vehicles and evacuate immediately when they have been warned from the government. This paper proposed two main objectives which area; 1) Evaluate Risk level of storm surge and relevant hazard in Bangkok Metropolitan Region (BMR) and 2) Evaluate potential evacuation by overlay between building density in Bangkok Metropolitan Region and road network. Geographic Information System (GIS) was employed to analyze hazard risk level with Spatial Analysis technique.

Abstract

Recently, Bangkok and its vicinities have been growing and become megacity. One of the main affects of land use and transportation interaction is the enormous societal loss in term of road traffic casualties. It requires a tool for safety vision as a proactive and integral approach to coordinate transportation and land use planning decision. This study explores the impacts of urbanization pattern on road safety base on three main driving factors which are physical conditions, economic opportunities and demographic growth together with plans and policies. The results could be compared with the different deterioration of safety level base on an application of severity approach and demonstrated by spatial techniques of aerial photo and geographical information system. With this tool, it is enable for more coordination among different stakeholders for improving road safety situation on an influence of the negative effects of sprawling development while promote sustainable transportation.

Abstract

Rapid development in center core of urban area motivates people from rural migrates to urban for reaching better quality of life. However, due to the hindsight between development planning and policies, and tangible development causing negative impacts on several dimension of urban living which includes increasing social isolation, unsafe condition and auto-dependency. This situation has affect social capital on both individual and communities level. Therefore, the aims of this study are (1) to identify the set of variables that influence on social capital formation in suburban area; (2) to determine the component factors that formulate social capital value in variety context of urban development; and (3) to analyze relationship among physical factors together with nonphysical ones for examine its effects. This study selected Thakhlong Municipality as a study area to perform spatial analysis for investigating different typology of social capital value among a variety group of residents disperse in urban fringe of commuter town character. Results from this study demonstrated that the formulation of social capital values influenced by the integrating effect of both physical characteristics of building agglomeration and social perspectives which was stimulated by land use policy and planning.

Abstract

Due to a force for development has resulted to rapid urbanization in Bangkok and its vicinities. The attractions of megacity create high number of jobs and opportunities, consequently accessibility and mobility has become super congested which has long been called for sustainable solution to tackle with this problematic of urbanization. A need to change the current supply leads to urgent need of an alternative mode choice for commuters, and adopt a new paradigm of mobilization where suburban urbanization evolves in Bangkokians’ daily life. This study aimed to provide an unconventional solution to meet the current mobility needs through the introduction of water transport systems that focus on access, safety and efficiency within the larger context of reducing commuting time in Bangkok urban areas. This effort through its various initiatives to return the role of Bangkok canal network in more sustainable option include the business model option along with social engagement of community people to own their water transport. Finally, this contribution could then help Bangkok not only towards urban mobilizing, but also for resilient and sustainable lowland cities under the risk of flooding in term of mitigation and management.
