“…On another aspect, using GIS methods to assess the impact of natural disasters (floods, droughts, salinization, etc.) is considered an effective method with the advantages of quick and accurate updates according to temporal and spatial changes of disasters [11] [28] [29] and [30]. ISSN: 1686-6576 (Printed) | ISSN 2673-0014 (Online) | © Geoinformatics International Since climate change vulnerability assessment generally uses an index-based approach, it is highly recommended to apply the GIS method for generating a set of indicators containing both spatial and attribute information.…”

This study aims at integrating GIS method and fuzzy AHP to evaluate the impact of climate change under the vulnerability concept. The results of this empirical study in Da Nang city have significant scientific contribution to the generation of comprehensive indicators for assessing the vulnerability in coastal cities in Central region of Vietnam. The approach of the Intergovernmental Panel on Climate Change (IPCC) in climate change vulnerability assessment has been examined considering three main components of vulnerability which are exposure to hazards, local sensitivity and adaptive capacity. GIS-based approach was applied to generate a set of indicators and the fuzzy AHP method was investigated for determination of the weighted scheme for parameters included in the climate vulnerability assessment. The study results indicate that the coastal districts including Son Tra and Ngu Hanh Son districts are most vulnerable to climate change due to high exposure, high sensitivity and limited adaptive capacity. On the contrary, the district with high level of adaptive capacity such as Hai Chau district is usually ranged in low level of vulnerability. The results confirm the importance of enhancing adaptive capacity in responding to the impact of climate change.

“…The first-order control on the spatial variance of hydrological conditions is topography [27]. The Digital Elevation Model (DEM) is one of the primary elements that contribute to flooding, since lower altitudes assume a greater flood hazard potential.…”

The objectives of this study are to mapping the hazard-prone area and to analyse the flood vulnerability index in Kobe Watershed, Central Halmahera District. In order to determine the optimal selection of weights for the factors that contribute to flood risk, GIS and multi-criteria decision analysis (MCDA) were used in conjunction with the application of the analytical hierarchy process (AHP) method to create the flood hazard map. The flood hazard map was generated by using selected hazard factors including land use, topography, slope, and rainfall pattern. The result shows that the Kobe River basin is a flood-prone area, with 77.46 percent of its land classified as less prone to flooding and 21.41 percent classified as flood-prone. However, only 21.41 percent of its land is classified as flood-prone. Only 1.13 percent of the land is protected from the danger of floods, compared to the whole country. The altitude factor is the most important element influencing flood susceptibility in Weda District, where the majority of the land (16.34 percent) is located at or below sea level, making it particularly vulnerable to flooding.
