“…To investigate whether there is a relationship between flood hazard and vulnerability in this study [111], we conducted a paired comparison of intensity between flood hazard and flood vulnerability. The result illustrates a significant level (p < 0.01) of the Pearson correlation coefficient with the value of r = −0.164 [112], showing a weak linear correlation [113]. The analysis of inverse correlation indicates that the two individual variables generally move in opposite directions in a statistical relationship.…”

“…Flood risk management embraces a broad range of strategies from the forecast of flood hazards and vulnerabilities to the social effects and risk-reduction measures and tools [44,122]. Flood risks assessment considers dynamics in the interconnected social-ecological-technological systems across temporal and spatial scales [112] and identifies a climate justicescape [20]. This study proposed a coupled nature-human approach that can better inform risk management and enhances urban resilience toward sustainable development pathways [33,34].…”

Developing countries in the global south that contribute less to climate change have suffered greater from its impacts, such as extreme climatic events and disasters compared to developed countries, causing climate justice concerns globally. Ho Chi Minh City has experienced increased intensity and frequency of climate change-induced urban floods, causing socio-economic damage that disturbs their livelihoods while urban populations continue to grow. This study aims to establish a citywide flood risk map to inform risk management in the city and address climate justice locally. This study applied a flood risk assessment framework integrating a coupled nature–human approach and examined the spatial distribution of urban flood hazard and urban flood vulnerability. A flood hazard map was generated using selected morphological and hydro-meteorological indicators. A flood vulnerability map was generated based on a literature review and a social survey weighed by experts’ priorities using the Fuzzy Delphi Method and Analytic Network Process. Vulnerability indicators including demographic characteristics, infrastructure, and land use patterns were used to generate a flood vulnerability map. The results illustrate that almost the entire central and northeastern parts of the city are at high flood risk, whereas the western part is at low flood risk. The findings have implications in urban planning via identifying risk hot spots in order to prioritize resources for mitigating hazards and enhancing community resilience to urban floods.

“…Vulnerability is simply a condition of a society that makes them potentially impacted by adverse hazards. Vulnerability is seen as a result of danger and is determined by the variables of vulnerability, sensitivity, and consequences of potential hazards [5][6][7][8]. The vulnerability can be seen from various variables that can increase the level of vulnerability to a hazard.…”

Vulnerability analysis toward river flooding in the Comal Watershed, Indonesia

et al. 2021

River flooding is a disaster that almost every year hits the downstream Comal watershed. This incident resulted in material, psychological, and even casualties. Therefore, a vulnerability analysis is needed to reduce the impact of flooding. This study aims to analyze the vulnerability to river flooding in the downstream Comal Watershed area, Indonesia. Vulnerability variables used are social, economic, physical, and ecological (environmental) vulnerability following the Indonesian National Disaster Management Agency (BNPB) Regulation 2012. Data were obtained from government agencies and interpretation of SPOT 5 satellite imagery. Data analysis were carried out using scoring and weighting. Moreover, the data classification were using the mean and standard deviation equations. The analysis showed that the vulnerability to river flooding in the Comal watershed area was dominated by a moderate vulnerable class of 10,832.15 hectares (49.69%) and distributed in 26 villages. Furthermore, the high level of vulnerability also covered a large area by 8,773.11 hectares (40.24%), and distributed across 29 villages. Therefore, proper river flooding mitigation planning with the characteristics of the area is needed.

“…Then, for each racial group with a positive ( +) relationship with COVID-19 (e.g., Native, Table 4 ), we normalized their values using a linear standardization formula to rescale values between 0 and 1 (Eq. 1 ) (Chang et al, 2021 ). i is the variable being analyzed, in this case either racial group or green space.…”
