<p class="a"><span lang="EN-US">Flood disaster has become a natural concern to the land owners where it raised a critical issue in term of land value depreciation. Previous studies have discussed the issue of potential decline in the value of land which are located on the flood-liable area. However, in Malaysia, current studies on flood impact are considered limited and do not focus on the effects of flood on land property. With the Hedonic Pricing Model (HPM) approach, we investigate the effect of flood on agricultural and industrial land property values in the urban and rural areas in Malaysia. The analysis indicates that the agricultural and industrial land values in the urban and rural areas have significantly decreased due to flood events. This study will benefit the land owners to understand the flood impact on land value and also the factors that contribute to the loss in the land value. It becomes the responsibility of the land owner to put the asset and property to its best use, given the presence of the flood. In addition, this study will help the policy maker to design and allocate land development efficiently in the urban or rural areas for agricultural and industrial project to ensure depreciation value of the land is minimized in the case of flood.</span></p>

Abstract. Glacial-dominated areas pose unique challenges to downstream communities in adapting to recent and continuing global climate change, including increased threats of glacial lake outburst floods (GLOFs) that can increase risk due to flooding of downstream communities and cause substantial impacts on regional social, environmental and economic systems. The Imja glacial lake (or Imja Tsho) in Nepal, which has the potential to generate a GLOF, was studied using a two-dimensional debris-flow inundation model in order to evaluate the effectiveness of proposed measures to reduce possible flooding impacts to downstream communities by lowering the lake level. The results indicate that only minor flood impact reduction is achieved in the downstream community of Dingboche with modest (~3 m) lake lowering. Lowering the lake by 10 m shows a significant reduction in inundated area. However, lowering the lake by 20 m almost eliminates all flood impact at Dingboche. Further downstream at Phakding, the impact of the GLOF is significant and similar reductions in inundation are likely as a result of lake lowering.

The development carried out in the last decades is degrading the ecosystems, damaging the existing biodiversity. One of the elements that is having the most impact on the deterioration of natural areas is the construction of transport infrastructures, among which are high-speed routes. These linear infrastructures are contributing to the deterioration of biodiversity enclaves, which contribute to providing highly relevant ecosystem services. Among these deteriorations are the processes of fragmentation and alteration of the landscape. This chapter analyses a situation that occurs in Spanish territory related to high-speed railways. This transport system began in Spain on the occasion of the Universal Exhibition of Seville 1992. By this transport activity, the changes suffered in the landscape are calculated and analysed through Corine land cover data since its inception until the last report of 2018.

Floods are among the most destructive natural hazards that cost lives and disrupt the socioeconomic activities of residents, especially in the rapidly growing cities of developing countries. Jeddah, a coastal city situated in Saudi Arabia, has experienced severe flash flood events in recent years. With intense rainfall, extensive coastal developments, and sensitive ecosystems, the city is susceptible to severe flash flood risks. The objective of this article is to apply an Analytic Hierarchy Process (AHP) model to explore the impacts of flash flood hazards and identify the most effective approaches to reducing the flash flood impacts in Jeddah using expert’s opinions. The study utilizes experts’ judgments and employs the AHP for data analyses and modeling. The results indicated that property loss has the highest probability of occurrence in the events of a flash flood with a priority level of 42%, followed by productivity loss (28%). Injuries and death were rated the least priority of 18% and 12%, respectively. Concerning flood impact reduction alternatives, river management (41%) and early warning system (38%) are the most favorable options. The findings could assist the government to design appropriate measures to safeguard the lives and properties of the residents. The study concludes by underscoring the significance of incorporating experts’ judgments in assessing flash flood impacts.
