“…Various GIS techniques are applied for analysing and overlaying data and establishing spatial relationships using distributed information. In addition, the Analytical Hierarchy Process (AHP) is applied to give spatial decisions and provides the weights to analyse the input indicators [40][41][42][43]. Flood risk assessment and flood risk mapping that include the analysis of flood hazard, exposure, and vulnerability can provide a useful resource for flood risk management, mitigation actions, and governance ( Figure 3).…”

Vietnam has been extensively affected by floods, suffering heavy losses in human life and property. While the Vietnamese government has focused on structural measures of flood defence such as levees and early warning systems, the country still lacks flood risk assessment methodologies and frameworks at local and national levels. In response to this gap, this study developed a flood risk assessment framework that uses historical flood mark data and a high-resolution digital elevation model to create an inundation map, then combined this map with exposure and vulnerability data to develop a holistic flood risk assessment map. The case study is the October 2010 flood event in Quang Binh province, which caused 74 deaths, 210 injuries, 188,628 flooded properties, 9019 ha of submerged and damaged agricultural land, and widespread damages to canals, levees, and roads. The final flood risk map showed a total inundation area of 64,348 ha, in which 8.3% area of low risk, 16.3% area of medium risk, 12.0% area of high risk, 37.1% area of very high risk, and 26.2% area of extremely high risk. The holistic flood risk assessment map of Quang Binh province is a valuable tool and source for flood preparedness activities at the local scale.

Important decisions are often taken by groups of decision-makers who need to choose among several alternatives in view of multiple objectives, in recognition of the interests of stakeholders. Such decision problems can be supported with the methods and processes of multicriteria decision analysis (MCDA) which foster collaboration, lend structure to the decision process, and help in managing problem complexity. In this chapter, we examine rationales for using MCDA methods in group decision processes, outline typical phases of these processes, summarize widely used MCDA methods and discuss some of their recent methodological extensions. We also provide guidelines for the design and implementation of MCDA-assisted group decision processes, based on an examination of behavioral factors and a structured review of selected case studies. We conclude with an outlook for the future in light of recent developments and trends.
