Three sustainability advantages of urban densification in a concentric urban form: evidence from Bandung City, Indonesia
No full textAmid limited land resource in Bandung city, pressure on the needs of lands continuously exists. Urban densification may create high density spaces and minimizes trip length by exploiting vertical growth. In contrary, sprawling city expands horizontally and creates low density spaces. Sprawling cities in most cases are motorized transport dependent cities. The study was carried out by analyzing the present form of Bandung City. Bandung City in Indonesia, a pronounced concentric-cum-sprawling city of a developing country, was selected as study area. The analysis covers three most determinative environment-related issues that lead to sustainability advantages of the city, since appropriately addressing the issues would likely contribute to sustainability of the city. These three issues are transport energy, flood, and groundwater depletion. Analysis on transport energy consumption in three urban development forms was carried out. The study result reveals that urban densification may lead to lower transport energy consumption as reflected in the mixed use areas compared to the other two urban development forms. The study also confirms that urban densification enables groundwater depletion to be minimized amid significant abstraction in the city and at the same time reducing flooding problems
The interplay of spatial policy, travel behaviour and air quality in Iskandar Malaysia
No full textIskandar Malaysia has been emerging as a centre of economic growth in the southern corridor of Malaysia. While the present spatial policy has emboldened the growth centre that inspires the urban development in the region to flourish, the spatial development has brought a substantial environmental consequence to urban areas. With the support of travel behaviour of the citizens as a catalyst, the interplay between spatial policy and urban air quality in the region becomes a major concern. This study began by undertaking spatial policy analysis at local and federal levels. Then, an origin-destination study was carried out to assess the travel behaviour of citizens and the concentricity or poly-centricity of the region as an eventual reflection of spatial policy. Based on the information on travel behaviour and number of vehicles in Iskandar Malaysia, the vehicle-kilometre travelled (VKT) was estimated as well as the carbon emission from the transport sector. An ethnographic survey was also conducted to understand the nonmotorized travel behaviour of the citizens i.e. willingness to walk. This survey was to crosscheck and confirm the willingness to walk of the citizens resulting from questionnaire survey. Results of the study reveal that the spatial policies of Iskandar Malaysia along with the travel behaviour of the citizens have strongly shaped the present spatial structure of Iskandar Malaysia region, and ultimately lead to ever increasing air pollution in the region
A Study on the Linkages between Residential Satisfaction and the Overall Quality of Life in Bandar Tun Razak Area of Kuala Lumpur City, Malaysia
No full textSpatial Pattern, Transportation and Air Quality Nexus: The Case of Iskandar Malaysia
No full textSpatial pattern, transportation, and air quality are three development entities which significantly affecting one another. This nexus exhibits the urbanization imprint accouter transportation generating air pollution as a reflection of spatial distribution. The integration among them is a vital part of development as it affects the societal living environment. It provides unfavorable air quality and directly cause health problems. The developing region of Iskandar Malaysia exhibits huge spatial distribution transformation accompanied by large percentage of urbanization rate, but seems less integration of land use and transportation planning which causes the exaggeration of air pollution. We carry out the research on the nexus of spatial distribution, transportation and air quality in Iskandar Malaysia by analyzing and evaluating the interconnectivity of these three entities. The spatial analysis and evaluation on the land use development pattern and spatial policy shows that the Iskandar development region are growing in the polycentric manners, where the spatial development policy drives the distributional growth of new sub-centers. We undertook a household-based travel survey that reveals the poly-centricity reflected by the de-concentration of workplaces which shifted from the single point towards multiple centers. On the other hand, this phenomenon has created a distributional traffic pattern amid the high dependency on the private vehicles of the citizens in Iskandar Malaysia. With a predominantly fossil fuel consuming vehicles, this has generated air pollution. Based on the traffic survey and the dependency of the citizens on private cars for their daily mobility, the concentration of air pollution is seemingly at risk. This research reflects that Iskandar Malaysia development region currently undergoes towards polycentric development with some new urban centers. We found that land use and transportation planning policies require serious attention as the current trend of spatial pattern development tends to reinforce high dependency on the motorized travel
Waterfront Development Concepts in Indonesia from the Perspective of Urban Planning and Environmental Sustainability
No full textRivers, lakes, beaches or other public water bodies have substantial and precious environmental values, and if properly managed, they can be a tremendous element towards a sustainable city. Within the context of urban planning and environmental sustainability, the harmonious balance between built and natural environment could not be avoided. The riverfront development concepts attempt to accomplish this balance by developing the necessary built environment while keeping the natural environment intact and provides ecological service. Since the concept of riverfront development is new to Indonesia or to most cities in Indonesia, it would be a good initiative to promote this concept. The riverfront development concept would bring the positive multiplier effects to urban development and ultimately to the well-being of urban citizens. This paper attempts to address the possibilities of riverfront development concept for its existence from the viewpoint of urban planning and environmental sustainability. This thought is based on personal lookout as well as relevant references. The study was carried out by observing some examples of waterfront development in some cities. Assessment on the regulations of riverfront related development was also undertaken. The study found that present approach on rivers or lakes or other public water bodies as the backyard of the development has brought to various environmental degradation. The riverfront concept is expected to reverse the situation for its numerous social, economic and environmental advantages. We suggest that this concept must be implemented elsewhere in Indonesia due to foreseeable returns towards sustainable urban development and sustainable cities.</jats:p
Barriers to implementation of environmental management measures in the operation of shop-house enterprise in Bangkok metropolitan area
Get PDFShop-house enterprises in Bangkok Metropolitan have so far been the best alternative of the citizens to earn income. At the same time, these enterprises also generate negative environmental and health consequences. While facing this dilemmatic situation, the implementation of environmental management measures (EMMs) to deal with environmental and health impacts generated by the enterprises is not presently practical. We identified some potential barriers. However, which one is the most influencing barrier to EMMs we must identify it. The study attempts to understand perceptions of different group of randomly selected stakeholders on the most influencing barriers given fourteen potential barriers to EMMs in Bangkok Metropolitan. The analysis shows that there are four essential barriers as perceived by the stakeholders that needs in-depth attention for the practical application of EMMs. By these critical barriers, policies should be directed to cope appropriately with the issues to accomplish better performance of shop-house enterprises in terms of environment and health
Understanding the Acceptance of Local Public Officers on Computer-based Urban Spatial Information System
No full textInformation technology is developed to assist people in minimizing processing time, reducing errors, increasing the accuracy and simplifying the overall process. The process of recording, retrieving and displaying data and information can thus be easily and accurately undertaken. Information technology in its initial development, however, tends to be too costly and complicated to make a real particularly for people in developing countries. Fortunately, universities as the centers of innovation, can be a game changer for the adoption of the innovative processes, for the benefits of the community at large. In all Indonesian universities, this role is associated with a, so called Tri Dharma Perguruan Tinggi (Three Devotions of Higher Education, TDHE). This paper examines the acceptance of the collaborating officials and the obstacles i.e. internal and environmental factors. We proposed the use of GIS-based technology to coordinate the administrative units of local government at all levels, particularly the Kelurahan as the lowest hierarchy of the administrative unit in local government system. The Kelurahan will then be the spearhead in a local government system in Indonesia in promoting administrative services to all Citizens. We undertook an integrated training and tutorial for select official staff of the Kelurahan on the system. Evaluation of shows that the information system can be used to simplify the collaborators’ activities. The evaluation was done through in-depth interview to the collaborating officials. The collaborators interested in learning more about the system as an innovative way in providing service to the community as well as spatial data input to support urban planning and management

URBAN SPATIAL PATTERN AND CARBON EMISSION INTERCONNECTIVITY IN A SUB-SAHARAN CITY, NIGERIA
No full textThis study analyses the spatial pattern of Kaduna City in Sub-Saharan region and its vicinity to ascertain its influence on urban interaction and implications towards carbon emission. It employed a questionnaire-based research for the collection of socio-economic, traffic and spatial data. Meanwhile, spatial data was derived in secondary form from relevant organizations. The study reveals a steady increase in the built-up areas which covered 17,121 hectares representing 53% of the total area of the city. It also identified a mono-centric land use pattern for the city. The interconnection between the city centre and the residential areas has resulted in high traffic volume during the morning and evening peak hours on working days. The study also found that carbon emission at points along major routes in the city ranges between 1169 to1884 ppm. Considering the present performance of the city, the study suggests to adopt traditional red-ocean strategies, which are maximizing the carbon sequestration through optimizing urban ecology while minimizing the need for motorized transport using urban planning principles.</jats:p
