Land Resource Sustainability for Urban Development: Spatial Decision Support System Prototype

Abstract

Land resource sustainability for urban development characterizes the problem of decision-making with multiplicity and uncertainty. A decision support system prototype aids in the assessment of incremental land development plan proposals put forth within the long-term community priority of a sustainable growth. Facilitating this assessment is the analytic hierarchy process (AHP), a multi-criteria evaluation and decision support system. The decision support system incorporates multiple sustainability criteria, weighted strategically responsive to local public policy priorities and community-specific situations and values, while gauging and directing desirable future courses of development. Furthermore, the decision support system uses a GIS, which facilitates an assessment of urban form with multiple indicators of sustainability as spatial criteria thematically. The resultant land-use sustainability scores indicate, on the ratio-scale of AHP, whether or not a desirable urban form is likely in the long run, and if so, to what degree. The two alternative modes of synthesis in AHP-ideal and distributive-provide assessments of a land development plan incrementally (short-term) and city-wide pattern comprehensively (long-term), respectively. Thus, the spatial decision support system facilitates proactive and collective public policy determination of land resource for future sustainable urban development.

Land-Use Planning for Urban Sprawl Based on the CLUE-S Model: A Case Study of Guangzhou, China

“…In general, the methods used to establish an index system differed in the various case studies. Methods of determining the weight of indicators developed in recent studies have included entropy, the Delphi technique, principal component analysis (PCA), and analytic hierarchy process (AHP) [10][11][12][13].…”

Semi-Urban Areas in Landscape Research: A Review

“…Good examples of decision support strategies as a tool for sustainable urban planning of semiurban areas include sprawl measures, master plans, neighborhood development tools, hierarchical processes for evaluation, growth management, and the implementation of green structures as an instrument and are abundant in the literature (Banai, 2005;Cadieux, 2008;Daniels and Lapping, 2005;Hümmeler, 1998;Jensen et al, 2000;Yli-Viikari et al, 2007). …”

Impacts of Planners' Different Viewpoints on Optimum Land-Use Allocation

“…MCDM techniques are classified into two groups; "Multi-criteria Analysis (MCA)" and "Multi-Objective Decision Analysis (MODA)". MCA techniques are used in the preparation of a land suitability evaluation map for a given land use/s or facility (Pereira & Duckstein, 1993;Malczewski, 1996Malczewski, , 2006bDai et al, 2001;Joerin et al, 2001;Banai, 2005;Natividade-Jesus et al, 2007), and in the evaluation and selection of the predetermined and limited number of allocation alternatives (Carver, 1991;Bodini & Giavelli, 1992;Zucca et al, 2007). MCA is a very simple and a useful evaluation and selection technique if alternatives are predetermined and limited in numbers.…”
