Abstract

Since at least half of the world’s population resides and works within coastal land, the coastal zone processes and resource management is of great economic and social importance. One of the fundamental issues for coastal city planners, researchers, managers, and engineers is the coastal city land-use suitability. Land-use suitability is the ability of a given type of land to support a defined use. Rapid urbanization and consequent haphazard growth of cities result in deterioration of infrastructure facilities, loss of agricultural land, water bodies, open spaces, and many micro-climatic changes. Hence, accurate data on coastal city hazards are essential and valuable tools for coastal planning and management, sustainable coastal development, coastal environment conservation, selection of a site for coastal city structures, and coastal resources. In this investigation, the Delphi and Analytical Hierarchy Process (D-AHP) Hybrid model and Geographic Information System (GIS) technique for Coastal Land-Use Assessment (CLUA) are mapped to detect the most suitable and unsuitable areas in the Kuala Terengganu coastal zone. Furthermore, this research offered information not only on the present urban land-use trend and established amenity status in Kuala Terengganu, but also on the suitability of land for the potential establishment of urban facilities for improved urban planning and appropriate decision-making. Using the D-AHP Hybrid model and GIS tool for coastal city management is broadly practical for government, policymakers, and planners to appropriately strategize and plan for the future of coastal cities in Malaysia and other analog coastal cities around the world.

Highlights

Land suitability assessment is a land evaluation approach that identifies the key qualitative and quantitative evaluation limiting criteria [1]
The environmental layers domain refers to the soil, slope, geology, digital elevation map, river, and land use
Understanding and determining land-use change causal indicators is critical for developing the coastal city hazard model in the research region

Summary

Introduction

Land suitability assessment is a land evaluation approach that identifies the key qualitative and quantitative evaluation limiting criteria [1]. Hydrology, topography, vegetation, and soil characteristics are examined in qualitative land suitability assessments, whereas the results are more thorough, and yield is calculated in quantitative assessments [2]. Coastal city land-use suitability assessment for agriculture, settlement, housing, and industry depends on its elements. These elements have been depleted, especially in the last few centuries [5]. Coastal city lands refer to the areas where natural and artificial variations happen most often [6]. The use of coastal zones by humans for housing, settlement, transportation, economy, and other purposes throughout history has resulted in artificial variations in these areas [7]
