GIS based integrated planning assessment for sustainable land use development

Development planning and assessment require an effective approach to achieve the desired goals and objectives, evaluate alternative as well as control development programs that are in line with the current and future prospects. The advent of information technology encouraged the integration of planning assessment and GIS approach for sustainable development. GIS technology has long been applied in planning activities which essentially include plans formulation as well as development control. The Manual for preparing the various levels of plan has provided that all plans use GIS technology in plan formulation. This paper sets out the information requirement and GIS functionalities, which are relevant to various plans especially the regional plan for Lembah Klang region. The dynamic nature of planning and monitoring of development in Klang Valley, the fastest growing region in Peninsular Malaysia, apparently requires a ‘tool’ for continuous evaluation and analysis of the current environment as well as the capacity for future development. As such, a new concept of evaluation model named Integrated Land use Assessment (ILA) was introduced within the prior developed “Application of Geographic Information System (GIS) for Klang Valley Region” (AGISwlk). The introduction of ILA as an integrated land use planning approach that exploits the GIS analysis capabilities, supported by the use of planning support systems is seen as a good mechanism for monitoring urban development. The ILA model developed is implemented through incorporation with the use of the What if? PSS which is a scenario-based, policy-oriented planning support system that uses increasingly available GIS data. Apart from that, a user interface is also developed to ease the access and preparation of data from the AGISwlk database to run the ILA model and generate alternative scenarios. This paper will discuss the approach, developed model and underlying concept of ILA and emphasise on the case study concerning the use of ILA model for generating alternative development scenarios in Klang Valley. To conclude, several issues raised in the study will be discussed

Integrated land use assessment (ILA) for planning and monitoring urban development

The dynamic nature of planning and monitoring of development in Klang Valley region requires for a „tool‟ for continuous evaluation and analysis of the current environment as well as the capacity for future development. As such, Integrated Land use Assessment (ILA) is introduced as a new concept within the “Application of Geographic Information System (GIS) for Klang Valley Region” (AGISwlk). The introduction of ILA as an integrated land use planning approach that exploits the GIS analysis capabilities, supported by the use of planning support systems is seen as a good mechanism for monitoring urban development especially in environmentally-sensitive areas (ESAs). ILA is also aimed at reducing causes of degradation to environmental quality due to rapid development and expansion of city limits which have either directly or indirectly affected environmental quality in Klang Valley. The ILA model is implemented through incorporation with the use of the What if? PSS which is a scenario base, policy-oriented planning support system that uses increasingly available GIS data to support community-based process of collaborative planning and collective decision making. This paper will discuss the approach, developed model and underlying concept of ILA and emphasize on the case study concerning the use of ILA for defining and mapping of ESAs. Several issues raised in the study will be discusse

Application of information and communication technology in urban planning and monitoring

Due to the complexity and uncertainty in the planning process in addition to the dynamic nature of urban planning and management, it is particularly important to have a well conceived information system, which can serve as the eyes and ears to development planning and monitoring processes. On the other hand, an effective urban planning and monitoring system will need to have the capabilities to accommodate strategic planning, facility management as well as problem solving. This paper will discuss various initiatives undertaken by several local urban governments through the application of information and communication technology (ICT) for improving the quality of urban planning and monitoring. Several related aspects such as the automation of the database, organisation of the system to facilitate ad-hoc query, analysis and development control as well as the use of planning support systems to enhance spatial modelling for the purpose of development planning and control will be the main focus. Development of web-based GIS to encourage public participation and establish system integration for data sharing between planning authorities will also be discussed

Decision support system for urban sustainability planning in Malaysia

Development planning requires an effective approach to achieve the desired goals and objectives, evaluate alternative as well as control development programs that are in line with current and future prospects. In the quest toward urban sustainability planning, a support tool in the form of an information system is required for enhancing analyses and deriving rational decisions. Planning support system (PSS) and decision support system (DSS) are among the tools for achieving quality planning for optimum development. They support the tasks of plan formulation, monitoring and review which inevitably involve the assembly and integration of geographic information and are known to be widely used in considering alternative spatial development strategies as well as assessing development potentials involved in land use planning. This article discusses various uses of DSS with a focus on its functionalities in supporting development planning and management at various level

GIS and planning support system for Klang Valley Region, Malaysia

Metropolisation process brings numerous benefits to the quality of urban life and environment but at the same time leads to problems such as uncontrolled development, urban sprawl, congestion and the increasing cost of public services to cater for new infrastructure. Apart from that socio-economic disparity between regions becomes more significant, compounded by increasing rate urban poverty and the risk of social exclusion. Thus, the activities of controlling and monitoring urban development are crucial. The understanding of the urban system that promotes urban growth is also imperative for the purpose of policy making, formulating development strategies as well as development plans preparation. Apparently, the dynamic nature of planning and monitoring of development such as in Klang Valley, the fastest growing region in Malaysia, necessitates a ‘tool’ for continuous monitoring, evaluation and analysis of current environment as well as assessing the capacity for future development. As such, the development of a comprehensive database and GIS-based planning application under the project named “Application of Geographical Information System for Klang Valley Region (AGISwlk)� was initiated in 1995. The implementation of AGISwlk had been directed toward organisation of the system to facilitate immediate query and analysis, monitoring of development planning as well as spatial modelling. The project had since undergone intensive enhancement in its database structure, data quantity and quality, analysis approach and techniques as well as system customisation and integration to include the ability to provide alternatives in development scenarios. The application was further enhanced to include the development of AGISwlk web-based GIS application and establishment of the Integrated Land use Assessment (ILA) model. This paper will discuss the development, organisation and application of GIS for urban metropolitan management of Klang Valley Region, Malaysia

Spatial planning and decision support system for urban metropolitan planning and monitoring: a case of Klang Valley, Malaysia

Planning methodology has changed over the years following the shift of emphasis from producing plan, which described a state of affairs expected of some future date, to one acknowledging the continuous and cyclical nature of planning. This necessitates planning be based on the identification of needs and goals, the formulation and evaluation of alternative courses of action and monitoring of adopted programmes. It can be traced that the development of planning support system run parallel from the ‘database’ to ‘information’ approach, starting from a focus on applied science in the 1960s through a profound consideration on the political process in the 1970s and to an emphasis on communication in the 1980s. The dynamic nature of planning and monitoring of development in Klang Valley, the fastest growing region in Peninsular Malaysia, apparently requires a ‘tool’ for continuous evaluation and analysis of current environment as well as the capacity for future development. Apart from managing the comprehensive GIS database, evaluation becomes an essential step in the planning process especially in selecting the appropriate development scenario alternative to be implemented. As such, the concept of Integrated Land use Assessment (ILA) was introduced through the “Application of GIS for Klang Valley Region� (AGISwlk) project. The ILA model developed is implemented through incorporation with the use of What-if Planning Support System, a scenario-based, policy-oriented planning support system. A user interface is also developed to ease the access and preparation of data from the AGISwlk database to run the ILA model and generate alternative scenarios. The introduction of ILA as an integrated land use planning approach that applies the GIS analysis capabilities while supported by the use of planning support system (What if?) is seen as a good alternative for achieving better and more rational decisions. The methodology was developed and organized based on the GIS spatial analysis process and planning support system framework as well as the identification of policy and strategy to be used as guideline and direction of study in achieving the desired output. The developed model is expected to dynamically support the preparation of the Klang Valley Regional Master Plan

Pendekatan penilaian kawasan sensitif alam sekitar menggunakan analisis multi-kriteria

Physical, socio-economic and environmental sustainability are the most important basis in preparing development plans. The assessment of environmentally sensitive areas (ESA) becomes an important agenda following rapid urban development, industrialisation and economic growth which lead to adverse impacts on the environment. Many methods of analysis have been adopted in the assessment of environmentally sensitive areas (ESA) subject to the needs and the study areas. This paper introduces the multi-criteria method as an approach in the assessment of ESA, and in the formation of a development scenario that can determine the best alternative for a development plan. The multi-criteria method emphasises subjective transparency and judgement in the selection of sets of alternatives that affects the interests of stakeholders and decision-makers. The integration of information technology into the planning process using Geographical Information System (GIS) with the capability of utilising and manipulating spatial and non-spatial data results in better and more rational planning decisions. Database development and spatial modelling provide new dimensions in the analysis, in the painting of current scenario, and in achieving better data presentation in the process of determining ES

Geospatial Mapping of Suicide-Related Tweets and Sentiments among Malaysians during the COVID-19 Pandemic

The government enacted the Movement Control Order (MCO) to curb the spread of the COVID-19 pandemic in Malaysia, restricting movement and shutting down several commercial enterprises around the nation. The crisis, which lasted over two years and featured a few MCOs, had an impact on Malaysians’ mental health. This study aimed to understand the context of using the word “suicide” on Twitter among Malaysians during the pandemic. “Suicide” is a keyword searched for on Twitter when mining data with the NCapture plugin. Using NVivo 12 software, we used the content analysis approach to detect the theme of tweets discussed by tweeps. The tweet content was then analyzed using VADER sentiment analysis to determine if it was positive, negative, or neutral. We conducted a spatial pattern distribution of tweets, revealing high numbers from Kuala Lumpur, Klang, Subang Jaya, Kangar, Alor Setar, Chukai, Kuantan, Johor Bharu, and Kota Kinabalu. Our analysis of tweet content related to the word “suicide” revealed three (3) main themes: (i) criticism of the government of that day (CGD) (N = 218, 55.68%), (ii) awareness related to suicide (AS) (N = 162, 41.44%), and (iii) suicidal feeling or experience (SFE) (N = 12, 2.88%). The word “suicide” conveyed both negative and positive sentiments. Negative tweets expressed frustration and disappointment with the government’s response to the pandemic and its economic impact. In contrast, positive tweets spread hope, encouragement, and support for mental health and relationship building. This study highlights the potential of social-media big data to understand the users’ virtual behavior in an unprecedented pandemic situation and the importance of considering cultural differences and nuances in sentiment analysis. The spatial pattern information was useful in identifying areas that may require additional resources or interventions to address suicide risk. This study underscores the importance of timely and cost-effective social media data analysis for valuable insights into public opinion and attitudes toward specific topics
