Business recovery from disasters: Lessons from natural hazards and the COVID-19 pandemic

Abstract: This paper compares economic recovery in the COVID-19 pandemic with other types of disasters, at the scale of businesses. As countries around the world struggle to emerge from the pandemic, studies of business impact and recovery have proliferated; however, pandemic research is often undertaken without the benefit of insights from long-standing research on past large-scale disruptive events, such as floods, storms, and earthquakes. This paper builds synergies between established knowledge on business recovery in disasters and emerging insights from the COVID-19 pandemic. It first proposes a disaster event taxonomy that allows the pandemic to be compared with natural hazard events from the perspective of economic disruption. The paper then identifies five key lessons on business recovery from disasters and compares them to empirical findings from the COVID-19 pandemic. For synthesis, a conceptual framework on business recovery is developed to support policy-makers to anticipate business recovery needs in economically disruptive events, including disasters. Findings from the pandemic largely resonate with those from disasters. Recovery tends to be more difficult for small businesses, those vulnerable to supply chain problems, those facing disrupted markets, and locally-oriented businesses in heavily impacted neighborhoods. Disaster assistance that is fast and less restrictive provides more effective support for business recovery. Some differences emerge, however: substantial business disruption in the pandemic derived from changes in demand due to regulatory measures as well as consumer behaviour; businesses in high-income neighborhoods and central business districts were especially affected; and traditional forms of financial assistance may need to be reconsidered.

Post-disaster recovery for family firms: The role of owner motivations, firm resources, and dynamic capabilities

Abstract: Natural disasters (e.g., earthquakes and pandemics) negatively affect firms and their stakeholders. These disasters disrupt the operations of firms and lives of people by generating a shock in the system. Small firms are especially vulnerable to the shocks and disturbances resulting from these disasters. Since small firms, especially family firms, are key economic contributors and agents of recovery in any community, understanding their post-disaster recovery processes is critical. Therefore, this study examines the post-disaster recovery processes of small family firms. We utilize a grounded theory approach to analyze and propose that resources and socioemotional wealth priorities influence the post-disaster recovery of small family firms. Utilizing the 8.8 Richter scale earthquake in Chile in 2010 as a natural disaster, we examine the eight-year lagged data of 20 small family firms with disrupted operations. Our findings have important implications for small firms experiencing the negative consequences of disruptions, including those experiencing the COVID-19 pandemic-induced disruption.

Social media use in disaster recovery: A systematic literature review

Abstract: Studies on the role of social media in disaster management have so far focused mainly on early phases of the disaster response process. Published evidence regarding the scope and effectiveness of social media use in the recovery phase is limited but promising. There is currently no study that provides a comprehensive picture of the current research landscape that can inform different groups who need to capitalise on social media for disaster recovery. The present study aims to address this research gap by conducting a systematic literature review of social media use in disaster recovery. The review analyses the relevant studies to identify any temporal variations in research activity, the social media platforms most frequently used in disaster recovery, their patterns of use by type of disaster as well as the geographical locations where the studies have focused. Importantly, the paper identifies and summarises research findings relating to social media use in various aspects of disaster recovery, including (1) donations and financial support, (2) solidarity and social cohesion, (3) post-disaster reconstruction and infrastructure services, (4) socioeconomic and physical wellbeing, (5) information support, (6) mental health and emotional support, and (7) business & economic activities. We envisage that this comprehensive review will support the disaster risk reduction community with the requisite knowledge to better explore social media for disaster recovery. Similarly, future research may find the study helpful for understanding the state of knowledge and identifying research gaps around social media use for disaster recovery.

A demand-supply framework for evaluating the effect of resource and service constraints on community disaster resilience

Abstract: Tools that quantify community disaster resilience are essential for informed decision-making on community disaster resilience improvement measures. One of the major research gaps in quantifying community disaster resilience are community disaster recovery simulations. Such simulations enable an insight into factors that enable a rapid and efficient community disaster recovery and vice versa. The iRe-CoDeS framework presented in this paper, simulates community disaster recovery as a time-stepping loop, where at each time step the interplay of demand and supply of community components for various resources and services dictates components’ ability to operate and recover. Disaster resilience of a community is then quantified using a multi-dimensional metric, where each dimension represents the unmet demand of a community regarding a certain resource or a service, labelled Lack of Resilience (LoR). This paper presents how such a demand/supply approach can be applied to account for resource and service constraints, impeding factors, that prolong component recovery and thus decrease community disaster resilience. Housing resilience of North–East San Francisco exposed to a Mw7.2 earthquake on the San Andreas Fault is quantified to illustrate the proposed approach. rWhale application framework recently developed at the NHERI SimCenter is used for this purpose, presenting how such a regional simulation on the effect of natural disasters on communities can be extended using the iRe-CoDeS framework to simulate community disaster recovery and quantify community disaster resilience. It is shown that housing resilience quantification results obtained in the case study focused on a part of San Francisco are in accordance with the existing estimates of housing resilience. The evolution of the post-disaster community-level supply and demand for recovery resources and services is obtained, identifying how and when the unmet demand for these resources and services impedes community recovery. Lastly, the effect of community’s ability to mobilize resources and services needed for its recovery on its disaster resilience is investigated.

Post-Disaster Communications: Enabling Technologies, Architectures, and Open Challenges

Abstract: The number of disasters has increased over the past decade where these calamities significantly affect the functionality of communication networks. In the context of 6G, airborne and spaceborne networks offer hope in disaster recovery to serve the underserved and to be resilient in calamities. Therefore, our paper reviews the state-of-the-art literature on post-disaster wireless communication networks and provides insights for the future establishment of such networks. In particular, we first give an overview of the works investigating the general procedures and strategies for facing any large-scale disaster. Then, we present technological solutions for post-disaster communications, such as the recovery of the terrestrial infrastructure, installing aerial networks, and using spaceborne networks. Afterwards, we shed light on the technological aspects of post-disaster networks, primarily the physical and networking issues. We present the literature on channel modeling, coverage and capacity, radio resource management, localization, and energy efficiency in the physical layer part, and discuss the integrated space-air-ground architectures, routing, delay-tolerant/software-defined networks, and edge computing in the networking layer part. This paper also includes interesting simulation results which can provide practical guidelines about the deployment of ad hoc network architectures in emergency scenarios. Finally, we present several promising research directions, namely backhauling, cache-enabled and intelligent reflective surface-enabled networks, placement optimization of aerial base stations (ABSs), and the mobility-related aspects that come into play when deploying aerial networks, such as planning their trajectories and the consequent handovers (HOs).

Working with Disaster-Affected Communities to Envision Healthier Futures: A Trauma-Informed Approach to Post-Disaster Recovery Planning

Abstract: Disasters are becoming increasingly common and devastating, requiring extensive reconstruction and recovery efforts. At the same time, the level of available resources and the need to rebuild can present opportunities for more resilient land use and infrastructure, and to build healthier, more equitable and sustainable communities. However, disaster-affected individuals may experience trauma and mental health impacts that impede their ability to engage in long-range recovery planning. It is essential to consider and address community trauma when engaging with disaster-affected communities and in developing plans for recovery. Planners and engineers from outside the community (including public, private and non-profit practitioners) are often brought in to support long-term recovery. Most of these practitioners (particularly those focused on longer-range recovery) have no training in how disasters can affect mental health or what this could mean for their interactions with individuals or communities. In order to acknowledge and address disaster trauma in community recovery and redevelopment, we propose a trauma-informed approach which aims to provide practitioners supporting post-disaster community recovery planning guidance, in order to: avoid the causation of harm by re-traumatizing communities; better understand community needs; make sense of observed behaviors and avoid potential roadblocks; avoid becoming traumatized themselves; and facilitate community healing.

Facilitating Typhoon-Triggered Flood Disaster-Ready Information Delivery Using SDI Services Approach - A Case Study in Hainan

Abstract: Natural disaster response and assessment are key elements of natural hazard monitoring and risk management. Currently, the existing systems are not able to meet the specific needs of many regional stakeholders worldwide; traditional approaches with field surveys are labor-intensive, time-consuming, and expensive, especially for severe disasters that affect a large geographic area. Recent studies have demonstrated that Earth observation (EO) data and technologies provide powerful support for the natural disaster emergency response. However, challenges still exist in support of the entire disaster lifecycle—preparedness, response, and recovery—which build the gaps between the disaster Spatial Data Infrastructure (SDI) already-in-place requirements and the EO capabilities. In order to tackle some of the above challenges, this paper demonstrates how to facilitate typhoon-triggered flood disaster-ready information delivery using an SDI services approach, and proposes a web-based remote sensing disaster decision support system to facilitate natural disaster response and impact assessment, which implements on-demand disaster resource acquisition, on-the-fly analysis, automatic thematic mapping, and decision report release. The system has been implemented with open specifications to facilitate interoperability. The typhoons and floods in Hainan Province, China, are used as typical scenarios to verify the system’s applicability and effectiveness. The system improves the automation level of the natural disaster emergency response service, and provides technical support for regional remote-sensing-based disaster mitigation in China.

Implementing a Pre‐disaster Recovery Workshop in Intramuros, Manila, Philippines: lessons for disaster risk assessment, response, and recovery for cultural heritage

Abstract: The Sustainable Development Goals have included cultural heritage in the development agenda. However, natural hazards threaten the existence of several historic districts, like Intramuros in Manila, Philippines. Pre-disaster recovery planning has gained ground as a promising approach to improve disaster preparedness and recovery, although it has yet to be widely utilised for cultural heritage preservation. The authors organised a pre-disaster recovery planning workshop, which helped observe the existing system of disaster management for cultural heritage in Intramuros. Heritage Values and Vulnerability Assessments, which were presented to heritage experts, disaster managers, and the local community at the workshop, were conducted. As disaster risk management for cultural heritage is largely unexplored, the workshop generated much interest among stakeholders, as this was the first time that contact had been facilitated among them. It successfully demonstrated the benefits of pre-disaster recovery planning to provide inclusive and better recovery outcomes for historic districts.تقدمًا باعتباره نهجًا واعدًا لتحسين التأهب للكوارث والإنعاش، وإن كان لا يزال يتعين استخدامه على نطاق واسع لحفظ التراث الثقافي. ونظم المؤلفون حلقة عمل للتخطيط للتعافي قبل الكوارث حيث ساعد ذلك على مراقبة النظام القائم لإدارة الكوارث للتراث الثقافي في انتراموروس. وأجريت في حلقة العمل، تقييمات قيم التراث والضعف، التي قُدمت إلي خبراء التراث ومديري الكوارث والمجتمع المحلي. وبما أن إدارة مخاطر الكوارث من أجل التراث الثقافي غير مستكشفة إلى حدٍ كبير، فقد أثارت ورشة العمل اهتمامًا كبيرًا بين أصحاب المصلحة، حيث كانت هذه هي المرة الأولى التي يتم فيها تيسير الاتصال فيما بينهم. وقد أثبتت بنجاح فوائد التخطيط للإنعاش قبل الكوارث لتوفير نتائج شاملة وأفضل للإنعاش في المقاطعات التاريخية. الكلمات الدليلية:

Recovery Capitals: a collaborative approach to post-disaster guidance

Abstract: Knowledge from past disasters can inform and support recovery, yet these insights are not always readily accessible to recovery practitioners. To bridge this gap, effective collaboration is needed to produce practical, evidence-based resources. This was the focus of the Recovery Capitals (ReCap) project, a collaboration between researchers and practitioners across Australia and Aotearoa New Zealand.

Why Do Communities Recover Differently after Socio-Natural Disasters? Pathways to Comprehensive Success of Recovery Projects Based on Bam’s (Iran) Neighborhoods’ Perspective

Abstract: Although recent studies have provided explanations for the causes of success and failure in recovery projects following socio-natural disasters, there is a need for a concise understanding of how different combinations of factors may contribute to recovery failure or success. In this study, to examine the community recovery pathways after the 2003 Bam earthquake, we conducted a fuzzy-set qualitative comparative analysis of 11 neighborhoods in Bam city and Baravat (the neighborhoods represent the division of the areas damaged by the earthquake, as presented by local government). The success of socio-natural disaster recovery projects is presented in three pathways in which the absence or presence of public engagement had a significant influence on the results. The results indicate that a recovery project should respond to the needs of the project within the continuous lifecycle of the project. Additionally, on the one hand, public participation and prompt rescue operations have a significant effect on project success. On the other hand, neglecting the needs of people and the area’s climate in housing design have led to project failure. It is expected that the findings from this study can be used to develop strategies for empowering people in recovery projects and to develop housing guidelines that respect residents’ needs while focusing on on-time and sufficient rescue processes. However, care should be taken when applying the present findings in practice, because every socio-natural disaster is unique and requires careful consideration of complex sets of features.

Evaluating the Importance of Interdependent Civil Infrastructure System Components for Disaster Resilience of Community Housing

Abstract: Housing disaster resilience is crucial for community disaster resilience as it provides two essential functions: shelter from the elements and functional housing. We present a methodology to quantify community housing disaster resilience considering the unmet post-disaster community demand for both shelter and functional housing. Total Sobol’ indices are used to evaluate the importance of the vulnerability and recoverability of individual components of community infrastructure systems and building stock units for community housing disaster resilience, while requiring no prior knowledge of these component properties. We illustrate the application of the proposed importance analysis on a virtual community considering the functionality of the electric power supply, water supply and communication infrastructure systems, and a number of building stock units.

Opportunity Among Disaster: Reflecting on 2 Disaster Scenarios During the COVID-19 Pandemic.

Abstract: Maintaining a public health emergency response for a sustained period of time requires availability of resources, physical and information technology infrastructure, and human capital. What perhaps is unprecedented is a medical center experiencing multiple disasters simultaneously. In this case study, the authors describe 2 separate disaster events experienced during the ongoing COVID-19 pandemic: (1) a cyberattack at Nebraska Medicine in Omaha, Nebraska, and (2) civil unrest following the murder of George Floyd in Minneapolis, Minnesota. Although these settings were very different, the following common themes can inform future disaster planning: the benefit of an already active incident command system, the prescient need for continuity of operations, and the anticipation of workforce fatigue. These dual-disaster experiences provide an opportunity to identify lessons learned that will drive improvements in emergency management through preparedness and mitigation measures and response innovations for future simultaneous disasters.

Simulating the role of transportation infrastructure for community disaster recovery

Abstract: Functional recovery of transportation infrastructure after a disaster is essential for community disaster resilience, as the recovery of damaged community components depends on their accessibility for repair. This paper presents a community disaster recovery simulation that accounts for community components' accessibility for repair using a demand–supply framework. The considered components of a community are viewed as suppliers and/or users of various resources and services essential for community functionality, reflected in components’ supply and demand properties. Whenever the demand of a component is not met, that component ceases to operate, simulating interdependency effects. Similarly, recovery demand is attributed to damaged components, representing the amounts of resources and services (e.g. workers, machinery and transportation services) that these components need to recover. The proposed framework is illustrated on a virtual community with 3600 inhabitants supported by several interdependent infrastructure systems. The results show that the transportation network damage slows down the recovery of the virtual community by preventing access to damaged components and reducing the ability of the community to mobilise available repair resources. Furthermore, the effect of such prolonged transportation system recovery on the damage-free infrastructure systems whose functionality was decreased due to their dependency on the affected infrastructure systems, is quantified.

Post-Hurricane Recovery Process: Analysis of the Public and Subject Matter Experts’ Perspectives Using Structural Equation Modeling (SEM)

Abstract: The increase in the number of hurricanes in recent years has impacted the affected communities in various ways, and the delays so often experienced by governors and federal authorities continue to be a significant issue. The direct impacts of the post-hurricane barriers on the recovery’s duration are frequently exacerbated by the impacts that some of the barriers have on each other, which can intensify their negative effects and lead to further delays. The aims of this study were to (1) investigate the relationships among the barriers to timely post-hurricane recovery, and (2) identify the extent to which the barriers and their interactions affect the timeliness of the recovery process according to experts’ and the public’s perspectives. A survey was developed to determine the impacts of 62 barriers that were identified as hindering timely post-hurricane recovery. Based on the collected data, two interrelated networks of the post-hurricane recovery barriers were developed, using the structural equation modeling (SEM) technique. The impacts of potential barriers on the duration of the recovery after hurricanes were analyzed, and the model based on the experts’ perspectives showed that coordination-related post-hurricane recovery barriers have the most major impacts on the length of the recovery. The model based upon the public’s perspectives indicated that social-related post-hurricane recovery barriers have the most impact on the duration of the restoration. This study will help post-disaster recovery planners understand the differences between the public’s and experts’ perspectives so that they can develop recommendations and strategies to prevent unnecessary delays.

Toward Sustainable Management of Disaster Debris: Three-Phase Post-Disaster Data Collection Planning

Abstract: Reuse/recycling is a major component of a management system for disaster-generated debris. Prior studies have identified several factors that affect the feasibility of post-disaster recycling programs, such as the amount of debris, potential health hazards, community priorities, economics, and disaster-specific funding policies and regulations. In order to better assess each of these factors for sustainable debris planning, there is a need to collect post-disaster data that become available at different points in time after disaster events. However, such data are rarely captured in a timely manner. The SUstainable Material Management Extreme Events Reconnaissance (SUMMEER) organization was formed with funding from the National Science Foundation to develop solutions to post-disaster materials management by investigating the impact of extreme events with a focus on the reuse and recycling of disaster materials. In this study, we introduce the roles and mission of SUMMEER to the construction research community. We propose a three-phase post-disaster reconnaissance framework that facilitates the collection of time-sensitive data from disaster sites that are critical for sustainable debris management research: (1) response, (2) short-term recovery, and (3) long-term recovery phases. This framework provides guidance on effective, coordinated field reconnaissance for sustainable debris management research.

Research and Practice on Security Protection and Disaster Recovery Strategy of Oracle Database in Colleges and Universities

Abstract: Database security protection, database backup and disaster recovery are important tasks for all colleges and universities to ensure the safe and stable operation of information systems. Based on the operating environment of the Oracle production database in China University of Geosciences (Beijing), combined with the practical operation and maintenance experience, this paper provides a design and implementation case of Oracle database security protection system and disaster recovery architecture. The network security protection architecture of the three-layer firewall and fortress machine, the detection and repair of security vulnerabilities, the management of system accounts and permissions, data encryption and database audit constitute the security protection system of the database. Oracle RAC (Real Application Clusters), Oracle DataGuard, redundant backup management and backup recovery constitute the disaster recovery architecture of the database. The case has practical significance for database operation and maintenance management in other colleges and universities.

Integrating Music into Natural Disaster Recovery

Abstract: Abstract The present research aims to highlight the value of incorporating music into natural disaster recovery toward the ultimate goal of better addressing human losses, economic damages, emotional/psychological struggles, and communal/cultural impacts resulting from natural disasters. Qualitative content analysis is the main methodology applied. Music therapy approaches are compared with ethnographic/ethnomusicological approaches at the personal, national, and international levels. The key finding is that the field needs to supplement music therapy approaches with ethnographic/ethnomusicological approaches to aid the recovery of disaster victims, while embracing a multidisciplinary approach, natural disaster management, human connectivity through music, sustainability, education, and training and exercise. This research contributes toward a comprehensive evaluation of not only the benefits but also the shortcomings of the above two approaches.

Design and Disaster Resilience: Toward a Role for Design in Disaster Mitigation and Recovery

Abstract: This paper examines how the discourses and practices of design can be applied to both mitigate the damaging impacts of (un-)natural disasters and guide resilient post-disaster recovery. Integrated with systems analysis, design can provide both an innovative window for understanding the complexities of disaster-risk reduction and recovery, as well as a conceptual bridge to new ways of building socio-economic and physical resilience in disaster-affected communities. However, the skills of key systems and design thinkers, such as architects, urban planners, and landscape architects, are seldom employed, despite their demonstrated capacity to work with disaster-prone or -impacted communities to develop integrated spatial responses to guide both disaster-risk reduction and long-term rebuilding after a disaster. Indeed, there has been little focused investigation of the potential contributions of design per se in developing strategies for disaster-risk reduction and recovery. Similarly, there has been little attention in design education to complementing the creative problem-solving skills of the designer with the contextual and systemic understandings of disaster management and disaster-resilient design. This paper addresses these omissions in both disaster management and design education though a review of research on design contributions to disaster issues and provides a case study of the curriculum and pedagogical approaches appropriate to build capacity for enhancing this contribution.

A failure detection method of remote disaster recovery and backup system

Abstract: Failure detection is one of the basic functions of building a reliable disaster recovery backup system. Aiming at the application-level disaster recovery backup failure detection problem, this paper analyzes the remote disaster recovery center architecture and failure detection hierarchy, and predicts the arrival time of cross-domain heartbeat information through the back propagation neural network based on particle swarm optimization (PSO-BP). When the actual timeout is reached, the active Auxiliary Detection (AD) is used to improve the correctness of failure detection, and finally the effectiveness of method PSO-BP-AD is verified through simulation.

Networks of recovery: Remittances, social capital and post-disaster recovery in Tacloban City, Philippines

Abstract: People exposed to natural hazards, especially those in weak states, depend on their social networks to survive. But in the face of disasters, such as Typhoon Haiyan that struck the Philippines in 2013, a household's local network is equally affected, and the household have needs to seek help from outside ties. After Typhoon Haiyan, migrants rose as a major source of assistance for post-disaster recovery. This study asks how does social capital and the types of social capital ties households affect remittance-receiving after disasters? Drawing from 72 interviews and 72 participant-aided sociograms with households in three heavily damaged communities in Tacloban City, this study found that middle income households have significantly more access and ability to receive remittances than lower income households. The study provides empirical support for more categories of social capital that are significant in post-disaster contexts: bonding ties that bridge space and bonding ties that link. Ultimately, access to social capital and the ability to mobilize remittances and other assistances from social ties impact a households' ability to recover after disasters.

Design and Implementation of a Software Disaster Recovery Service for Cloud Computing-Based Aerospace Ground Systems

Abstract: The data centers of cloud computing-based aerospace ground systems and the businesses running on them are extremely vulnerable to man-made disasters, emergencies, and other disasters, which means security is seriously threatened. Thus, cloud centers need to provide effective disaster recovery services for software and data. However, the disaster recovery methods for current cloud centers of aerospace ground systems have long been in arrears, and the disaster tolerance and anti-destruction capability are weak. Aiming at the above problems, in this paper we design a disaster recovery service for aerospace ground systems based on cloud computing. On account of the software warehouse, this service adopts the main standby mode to achieve the backup, local disaster recovery, and remote disaster recovery of software and data. As a result, this service can timely response to the disasters, ensure the continuous running of businesses, and improve the disaster tolerance and anti-destruction capability of aerospace ground systems. Extensive simulation experiments validate the effectiveness of the disaster recovery service proposed in this paper.

The effect of disaster case management on housing recovery:analysis of disaster survivor support in sendai city using synthetic control method

Abstract: This study investigated how disaster case management and disaster public housing reconstruction influence housing recovery using four open-data sources. It analyzed the trends in the number of households under designated temporary housing in Sendai and 18 other cities (19 cities in total) in Miyagi Prefecture. Results revealed that both disaster case management and the reconstruction of public housing for disaster recovery promote housing restoration from temporary housing. Furthermore, the study referred to Mary Richmond’s discussion of wholesale and retail methods to elucidate policy implications for disaster victim support.

Living with flux in the Philippines: Negotiating collective well‐being and disaster recovery

Abstract: Anthropogenic climate change poses huge challenges to humanity. The frequency and magnitude of extreme weather is increasing. As more attention turns to disaster preparedness and recovery, it is worth recognising that many communities have a long history of living with the flux of planetary dynamism. They are experienced in negotiating collective well-being with one another and with the earth. Other communities have less experience and know-how and have had to adopt more experimental approaches. In this paper we draw on planetary social thought and critical disaster studies to re-think disaster recovery. We present stories of communities in the Philippines differently negotiating collective well-being in the face of climate uncertainty.
