Changing climate dynamics have resulted in a confluence of disaster events to which Louisiana government leaders and emergency managers have never before had to respond simultaneously: a global pandemic and an “epidemic” of landfalling hurricanes during the 2020 season (eight cones over Louisiana) with challenging, unusual characteristics: (1) two hurricanes passing over the same location within 36 hours, a fujiwhara – Hurricanes Marco and Laura, (2) 150 mile-per-hour winds inadequately forecasted and of an almost unprecedented speed, (3) a difficult to forecast surge magnitude that led to incorrect immediate response, (4) delayed long-term recovery efforts from responders outside of the area because of initial reporting errors regarding surge heights and wind speed, and (5) a storm, Zeta, that passed directly over a densely populated area that would have been hard hit by rain if the storm had slowed. In addition, the number and closeness in dates of storm occurrences led to lengthy coastal high-water levels. To these co-occurring threats forecasters, state and local officials and residents responded with expertise and commitment, adhering to close collaboration, modifying evacuations and undertaking protective measures, all contributing to a low death rate from storms and a modest death rate from COVID. More just outcomes were supported by the general capacity of the responders, commitment to keep the residents informed about both risks and appropriate responses to them and the provision of special services, calculated for the new situation of the pandemic and the storm epidemic, for those without the means to respond adequately to both.

Engineering knowledge continuity is crucial for the life cycle management of long-lived and complex assets, such as nuclear plants, locks and storm surge barriers. At the storm surge barriers in the Netherlands, engineering knowledge continuity is not yet fully assured, despite long-standing efforts. This study aims to explore the relationship between system characteristics, the organizational demarcation of maintenance and operation and the challenges in achieving engineering knowledge continuity and provides suggestions for improvement of theory and policy.

Ten semi-structured interviews were conducted with professionals from various backgrounds in construction, engineering and asset management of the Dutch storm surge barriers, augmented with visits to barriers and barrier teams. A thematic analysis was used to identify and describe the challenges to engineering continuity, their origins and potential solutions. We reviewed knowledge management policy documents and asset management consultancy reports to validate the findings. Additionally, we engaged in frequent interactions with professionals at the barriers. We achieved saturation and validation once no new issues were raised during these discussions.

The thematic analysis developed multiple themes describing the challenges to engineering continuity, their origins and potential solutions. The key findings are that expert engineers are critically important to deal with redesigns induced by obsolescence. Moreover, due to barrier uniqueness, long redesign cycles and reliability requirements, conventional knowledge continuity tools are insufficient to enable new engineers to reach expert level. Finally, the thematic analysis shows that, in some cases, outsourcing should be reduced to facilitate internal learning.

The study introduces the application of the knowledge-based view of the firm and the concept of requisite knowledge redundancy to the long-term management of complex assets. It calls for more attention to long gaps in the use of unique knowledge and the effect on knowledge continuity.

Quantitative and spatial-explicit flood risk information is of great importance for strengthening climate change adaptation and flood resilience. Shanghai is a coastal megacity at large estuary delta with rising flood risks. This study aims to quantify the overall economic-societal risks of storm flooding and their spatial patterns in Shanghai.

Based on multiple storm flood scenarios at different return periods, as well as fine-scale data sets including gridded GDP, gridded population and vector land-use, a probabilistic risk model incorporating geographic information system is used to assess the economic-societal risks of flooding and their spatial distributions.

Our results show that, from 1/200 to 1/5,000-year floods, the exposed assets will increase from USD 85.4bn to USD 657.6bn, and the direct economic losses will increase from USD 3.06bn to USD 52bn. The expected annual damage (EAD) of assets is around USD 84.36m. Hotpots of EAD are mainly distributed in the city center, the depressions along the upper Huangpu River in the southwest, the north coast of Hangzhou Bay, and the confluence of the Huangpu River and Yangtze River in the northeast. From 1/200 to 1/5,000-year floods, the exposed population will rise from 280 thousand to 2,420 thousand, and the estimated casualties will rise from 299 to 1,045. The expected annual casualties (EAC) are around 2.28. Hotspots of casualties are generally consistent with those of EAD.

In contrast to previous studies that focus on a single flood scenario or a particular type of flood exposure/risk in Shanghai, the findings contribute to an understanding of overall flood risks and their spatial patterns, which have significant implications for cost-benefit analysis of flood resilience strategies.

The purpose of this paper is to focus on the local-level initiatives through coastal afforestation, the natural and socio-economic context of the study area (Hatiya Upazila of Noakhali District, Bangladesh) and the adaptation and DRR strategies generated through coastal afforestation in coastal Bangladesh.

Field observations, focus group discussions (FGDs), semi-structured interviews, and transects were accomplished in both the dry and wet season. Spatial database generated and land use mapping integrated social and technical investigation. Five FDG sessions with participants from different livelihood options (fishermen, farmers and social representatives) were organised and, on average, 15~18 participants participated in each participatory session.

Mangrove plantation can be used to access new land and create alternative livelihoods, which are important for local community adaptation and to reduce disaster risks. Mangrove plantations provide chances for new land management options to be developed for use in Bangladesh.

This study was conducted only at the south-central coastal district of Bangladesh. Data collection to summarise all the socio-economic issues is limited.

This paper can be used for the integration of geospatial and social research techniques to understand the community approach to fight against climate change-induced impacts.

The research is solely conducted by the authors. The conducted approach is a blend of social and technical knowledge and techniques in generating community resilience at the south-central coast of Bangladesh.

The purpose of this paper is to develop a multidimensional approach for effectively managing natural disasters; this paper has three research objectives. First, it provides an analysis on the hydro-geomorphological effects of the cyclone in the urban context. Second, it proposes an analysis for the vulnerability and resilience recovery of the populations living in urban areas. Third, it specifies the implications for sustainable recovery and longer-term disaster risk reduction.

A detailed case study of the tropical cyclone Pam was carried out to identify hydro-geomorphologic effects and damages in an urban area and specific problems associated with managing natural disaster in Vanuatu.

The investigations reveal that living in an urban area increases a population’s exposure to hydrological, weather and sea-related risks. Whereas advice on cyclones seems to work very well, the coastal risks and floods seem to be underestimated with a very high exposure and vulnerability to risk. Pre-existing vulnerabilities were exacerbated after cyclone Pam. However, other communities have been able to reinforce their resilience through local initiatives. The government and outside aid were very quick to react, despite problems of coordination, exchange of information, communication and long-term strategy.

The bottom-up, top-down, local and global approaches, applied on the time scales, should lead to actions that will reinforce the ability of the people of Vanuatu to adapt to high-energy events and to the effects of climate change.

This paper highlights the importance of understanding how the urban communities are vulnerable to natural hazards and of strategies for increasing their resilience.

This chapter highlights ecosystem-based adaptation in coastal Bangladesh aimed at securing climate and disaster-resilient environment for safer life and livelihood for vulnerable communities in the face of changing climate. Development intervention based on the opportunities offered by the nature and adaptation management plan from the perspective of vulnerability analysis can make a substantive difference in enhancing resilience. Engagement of broad-based stakeholders at vertical and horizontal levels in building adaptive capacity can be linked through both at the policy and institutional levels as well as at ecosystem levels for effective results. Innovation in convergence of disaster risk reduction and adaptation through fish, fruit, and forest as a part of livelihood integrated into the coastal afforestation ensure better livelihood in a safer coastal habitats. Such forest-based adaptive livelihood and carbon sequestration help land development that is promising to offset the sea level rise due to higher rate of siltation. Climate resilient habitat is another innovative initiative that protects the households, and their livelihood is protected by eco-engineering structures and green defense to make it safer from cyclone and tidal surge.

The Sundarbans is a unique ecosystem, the most expansive mangrove system in the world covering the Ganga–Brahmaputra–Meghna delta system and spread over 10,000 sq.km across India and Bangladesh. The Indian Sundarbans have been witnessed to large-scale conversion of mangroves to settled agriculture and steady growth of population over the decades. With time, while population growth has taken place, there has been no significant change in the development scenario, as the agriculture and fishing dependent communities have remained trapped in the vicious cycle of poverty. Its deltaic location and its position in the path of cyclones, tidal surges and seasonal floods have made the people and landscape of Sundarbans more vulnerable than ever before. Cyclones affecting this region have grown both in frequency and intensity over the years and have caused devastation to the land, homes, lives and livelihoods. The problem of salinity has also affected the region relentlessly. Given this scenario, scenario of progressing vulnerabilities, livelihood losses have led to a gradual increase in out-migration of the adult male population. This disaster-led outmigration from Sundarban region as a whole has affected the social fabric of displaced communities to a great extent. This chapter makes an attempt to discuss results of sample surveys across six villages in three CD Blocks of Sagar, Gosaba and Kultali to trace the nature and dimension of the migration patterns of the region.

This is a case of a crisis project management which showcases the unpredictable nature of the project and the role of management in handling the crisis. It is the case of a very severe cyclonic storm hitting the city of Visakhapatnam plant during October, 2014. The whole city was devastated and so was the situation in the Steel plant as it was under zero power conditions for around 10 days. This case gives need for managing an integrated steel plant in case of very severe cyclonic storm and documents the sequence of events and managing unforeseen uncertainty using NTCP concepts.

The study aims to assess the effectiveness of prevailing methods for quantifying physical climate risks. Its goal is to evaluate their utility in guiding financial decision-making within the real estate industry. Whilst climate risk has become a pivotal consideration in transaction and regulatory compliance, the existing tools for risk quantification frequently encounter criticism for their perceived lack of transparency and comparability.

We utilise a sequential exploratory mixed-methods analysis to integrate qualitative aspects of underlying tool characteristics with quantitative result divergence. In our qualitative analysis, we conduct interviews with companies providing risk quantification tools. We task these providers with quantifying the physical risk of a fictive pan-European real estate portfolio. Our approach involves an in-depth comparative analysis, hypothesis tests and regression to discern patterns in the variability of the results.

We observe significant variations in the quantification of physical risk for the pan-European portfolio, indicating limited utility for decision-making. The results highlight that variability is influenced by both the location of assets and the hazard. Identified reasons for discrepancies include differences in regional databases and models, variations in downscaling and corresponding scope, disparities in the definition of scores and systematic uncertainties.

The study assists market participants in comprehending both the quantification process and the implications associated with using tools for financial decision-making.

To our knowledge, this study presents the initial robust empirical evidence of variability in quantification outputs for physical risk within the real estate industry, coupled with an exploration of their underlying reasons.

Historians have interpreted the record of human struggle for survival in different ways, varying from a pessimistic to a cautiously optimistic approach. But there is no doubt that human destiny is shaped by the success or failure of human responses to challenges faced collectively as a society (Pendse). Historical records suggest that natural disasters, human violence, and war are common; humans and human groups are also quite capable of using violence and/or collaboration in the process of seeking resources, establishing status, and dominating other humans (Robert, Norwood, & Fullerton, 2004).
