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

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.

Typologies of Posttraumatic Stress Disorder in the Bam Adult Population: 17 Years After Bam Earthquake

Posttraumatic stress disorder (PTSD) is one of the most important issues after earthquakes. Following the Bam earthquake, much of the literature has documented the prevalence and correlates of PTSD, but no study has evaluated predominant typologies of PTSD in this population. The present study aims to investigate PTSD typologies among adults exposed to the Bam earthquake after 17 years. The data were collected 17 years after the 2003 Bam earthquake using multistage cluster sampling, in a historical cohort study. In total, 917 people participated in the study. Latent class analyses (LCA) were conducted to identify predominant typologies of PTSD symptoms and associated correlates. The LCA identified four meaningfully different classes that were characterized based on the PTSD items. The common profile was class 1 with 36.1% of the study population, which reported medium on “Re-experiencing” and “avoidance” items and high for “dysphoria” item. Also, the results showed significant differences for marital status, death relative, and age across the four classes of PTSD. The results indicated after 17 years of the Bam earthquake, people who were exposed to this earthquake were divided into subgroups based on the severity and prevalence of PTSD symptoms. These findings highlighted the existence of experimental subgroups of PTSD symptoms following an earthquake, which can help us find those who are most in need of mental health services and also which can find specific interventions for any subgroups.

Disaster governance as the governance of decentralized systems: the case of the 2003 Bam earthquake in Iran

PurposeThis study aims to yield significant insight into decentralized Disaster Governance (DG), explaining the passage from selecting actors and defining actions to determining outcomes in a decentralized process.Design/methodology/approachWe adopt the systems thinking approach to investigate the reconstruction program after the 2003 Bam earthquake in Iran. In-depth interviews are our main source of data that are carefully triangulated with findings from the review of documents and our direct observations.FindingsWe detected many shortcomings in this program, among which incomplete decentralization is highly prominent. In the Bam recovery program, tasks were delegated to varied actors based on their capacities without considering potential conflicts of interests and their unbalanced authority to serve their benefits. Meanwhile, the impact of the country's unstable political climate on restricting or liberating actors' influence on the recovery program was overlooked. These split relationships between DG components finally obstructed decentralization by intensifying conflicts of interest, which eventually compromised recovery objectives.Practical implicationsThe results reveal the importance of adopting mechanisms to ensure monitoring systems' and governments' neutrality and limit any political influence over the outcomes.Originality/valueDG concept is relatively new in disaster literature and despite its advancement in the last two decades, many studies still contribute to the epistemology of DG and its assessment methodology. However, the relationship between DG's components remains still obscure. This study tries to bridge this gap and make the concept more practical.

Post-Disaster Collaboration between Governmental and Non-Governmental Stakeholders: The Case of Bam Earthquake, Iran

Research on cross-sector collaboration has grown over the past decade. This model of collaboration brings organizations in two or more sectors together, to link or share information, resources, activities and capabilities when no single organization has enough time, money, knowledge or authority to address them alone. In a post-disaster period, the governmental organizations particularly in developing countries usually are unable to provide all necessary services alone; hence, collaboration with other agencies is required. In the last decades, studies have used the viewpoint of collaboration between NGOs and the government, and shown a beneficial relationship between them. Most studies have focused on the structures of the collaboration in the aftermath of disasters with hierarchies, protocols, authoritarian roles and the standardization of procedures but there is a gap in analysing the process factors and the interaction of process and structural factors influencing the collaboration during post-disaster period. In this study, the aim is to identify the main factors of process and structures influencing the collaboration between Iranian government and NGOs after the earthquake in Bam city in Iran in 2003. Analysing the content of the previous studies showed that lack of experience on how to deal with disasters and unclear tasks as well as insufficient trust and mutual understanding between the actors were the main reasons of failure in collaboration. The lack of specific organizational tasks at a given time led to exacerbate the tension in the process of working together; increase the lack of common understanding, and fail to achieve the mutual goal.

Effects of secondary static stress triggering on the spatial distribution of aftershocks, a case study, 2003 Bam earthquake (SE Iran)

<p>Immediate after a large earthquake, accurate prediction of spatial and temporal distribution of aftershocks has a great importance for planning search and rescue activities. Currently, the most sophisticated approach to this goal is probabilistic aftershock hazard assessment (PASHA). Spatial distribution of the aftershocks fallowing moderate to large earthquakes correlate well with the imparted stress due to the mainshock. Furthermore the secondary static stress changes caused by smaller events (aftershocks) could have effect on the triggering of aftershocks and should be considered in the calculations. The 26 December 2003 (Mw 6.6) Bam earthquake with more than 26000 causalities is one of the most destructive events in the recorded history of Iran. This earthquake was an interesting event and was investigated in a majority of aspects. Good variable-slip fault model and precise aftershocks data enabled us to impart Coulomb stress changes due to mainshock and secondary static stress triggering on the nodal planes of aftershocks to learn whether they were brought closer to failure.</p><p>We used recently published high-quality focal mechanisms and hypocenters to reassess the role of small to moderate earthquakes for static stress triggering of aftershocks during the Bam earthquake. By imparting Coulomb stress changes due to the mainshock on the nodal planes of the 158 aftershocks we showed that 77.8% (123 from 158) of the aftershocks received positive stress changes at least in one nodal plane. We also calculated Coulomb stress changes imparted by the mainshock and aftershocks (1≤M≤4.1) onto subsequent aftershocks nodal planes and found that 81.6% (129 of 158) of aftershocks received positive stress changes at least in one nodal plane. In summary, 77.8% of aftershocks are encouraged by the main shocks, while adding secondary stress encourages 81.6%. Therefore, by adding secondary stress the Coulomb Index (CI), the fraction of events that received net positive Coulomb stress changes compared to the total number of events, increased from 0.778 to 0.816.</p>

Sequential ambiguity and uncertainty in the early stage of a disaster relief: A case study of the Bam earthquake

This study aimed to identify issues that arose during the early response stage of the Bam earthquake as perceived by the aid workers. Eleven people who had been involved in the Bam earthquake response, and who were working for the Red Crescent in Iran or the Kerman University of Medical Science teams, were interviewed. These groups were two of the main organizations providing assistance to victims of the Bam earthquake. The authors used two nonrandom sampling methods, namely, purposive and snowball sampling. The interviewees identified two main barriers for achieving an effective response at the early stage aftermath of the earthquake, as follows: first, the lack of accurate information on the location and extent of the earthquake due to shortage in communication tools and, second, inadequate training on different challenges posed in relation to the disaster, before the earthquake occurred.

Evaluation of the Impacts of Identity and Collective Memory on Social Resilience at Neighborhood Level using Grounded Theory

In this paper, a new approach for evaluating the impacts of identity and collective memory (CM) on social resilience will be presented. The approach is applied in Bam city, located in Iran, which suffered heavy damage during the 2003 Bam earthquake. Following that disaster, little attention was paid to preserve identity and CM during the reconstruction phase. In order to evaluate the social resilience components, key concepts and core categories on a local level have been identified, using Grounded Theory. The results depicted that identity and collective memories in Bam city, have been diminished gradually, due to neglecting the intangible needs of local residents in the reconstruction. Therefore, this article demonstrates the necessity of attention to the revival of collective memories in the renovation and reconstruction policies. The results of this study can be used by disaster management authorities as well as city managers to improve resilience at the local level.
