Post-disaster periods are usually divided into four phases. The terms established by the United Nations Development Programme for post-disaster phases—relief, early recovery, recovery, and development—are used in this article. This research examines the hypothesis that the boundaries between post-disaster recovery phases are fuzzy and should be defined by the progress achieved in the recovery process, rather than by the amount of time elapsed since the event. The methodology employed involved four steps: fieldwork, mapping,identification of indicators, and assessment. The case study area was the city of L'Aquila in the Abruzzo region of central Italy, which was struck by an earthquake in April2009. For each phase of the recovery process in L'Aquila a score was calculated based on the progress observed in2016, 7 years after the earthquake. The highest score went to the early recovery phase(14 points), followed by the recovery phase(13 points), the development phase(12points), and the relief phase(4 points). The results demonstrate the possibility of defining post-disaster recovery phases in an affected area based on measuring achievements through indicators rather than defining recovery phases in terms of elapsed time after a disaster.展开更多

This article showcases the effects of a culturally relevant and sustainable psychosocial capacitybuilding project at the epicenter of the 2008 Wenchuan Earthquake. Specifically, the project focuses on women, a group that has received limited attention in post-disaster recovery in China. This qualitative research study(N = 14)sheds light on the characteristics and processes of the implementation of a post-disaster psychosocial intervention project in rural China. In addition, by adopting the Success Case Method as an evaluation approach, this study elucidates its effects on the psychological and social changes of the disaster victims. The findings capture five aspects of psychosocial changes: enriched daily life, better mood,enhanced self-confidence, increased willingness to socialize, and the provision of mutual help. This study hopes to encourage more culturally relevant and empowering practices for women in building their psychosocial capacity after disasters.展开更多

Sustainability implications of measures are captured by investigating the persistence of the social and economic living conditions in relation to post-disaster measures, and the alignment of the measures with basic environmental aspects. Based on major concepts relevant in disaster science and sustainability research, the study explored sustainability aspects of post-disaster measures implemented after the 2004 tsunami, by conducting selected interviews among the participants of the 2015 international seminar ‘‘11 Years after the Indian Ocean Tsunami 2004'' and a broader online survey. Information was sought about(1) the current state of vulnerability of the local population in the regions affected;(2) the main lessons that have been identified to improve project design and management of recovery and vulnerability reduction;and(3) project sustainability implications with respect to the state of today's vulnerability. Based on the analysis of the information on these three priority areas, selected tasks for future disaster risk management are identified, such as more integrative planning and improved coordination with international organizations and local people.展开更多

Revealing the post-disaster economic development and recovery process is very important for enhancing disaster prevention and response capacity in order to formulate control policies and recovery methods for post-disaster economic reconstruction based on economic resilience. Using long-term socioeconomic data and the autoregressive integrated moving average (ARIMA) model, this paper calculated the economic resilience index of the areas most severely affected by the Wenchuan Earthquake of 2008 and adopted the improved variable returns to scale (VRS) date envelopment analysis (DEA) model and the Malmquist productivity index to analyze the efficiency and effect of annual post-disaster recovery. The results show that: (1) the economic resilience index of the areas most severely affected by the Wenchuan Earthquake was 0.877. The earthquake resulted in a short-term economic recession in the affected areas, but the economy returned to pre-quake levels within two years. In addition, the industrial economy was less resilient than agriculture and the service industry. (2) The comprehensive economic recovery efficiency of the disaster-stricken area in the year following the disaster was 0.603. The comprehensive efficiency, the pure technical efficiency, and the scale efficiency of the plain and hilly areas were significantly greater than those of the plateau and mountain areas. (3) The annual fluctuation in total factor productivity (TFP) following the disaster was considerable, and the economic recovery efficiency decreased significantly, resulting in a short-term economic recession. The TFP index returned to steady state following decreases of 33.7% and 15.2%, respectively, in the two years following the disaster. (4) The significant decrease in the post-disaster recovery efficiency was caused mainly by technological changes, and the renewal of the production system was the leading factor in determining the economic resilience following the disaster. With the decline in the scale of economic recovery following the earthquake, long-term economic recovery in the disaster-stricken areas depended mainly on pure technical efficiency, and the improvement in the latter was the driving force for maintaining the long-term growth of the post-disaster economy. Therefore, according to the local characteristics of natural environment and economic system, the disaster-stricken areas need to actively change and readjust their economic structures. At the same time, attention should be paid to updating the production system to enhance the level of technological progress and give full play to the scale effects of large-scale capital, new facilities, human resources, and other investment factors following the disaster so as to enhance the impact of economic resilience and recovery efficiency in response to the disaster.展开更多

Research in this field to date generally suggests GSV is a reliable means of understanding the ‘‘real world'' environment. But limitations around the dates and resolution of images have been identified. An emerging strand within this literature is also concerned with the potential of GSV to understand recovery post-disaster. Using the GSV data set for the evacuated area around the Fukushima Dai'ichi nuclear power plant as a case study, this article evaluates GSV as a means of assessing disaster recovery in a dynamic situation with remaining uncertainty and a significant value and emotive dimension. The article suggests that GSV does have value in giving a high-level overview of the postdisaster situation and has potential to track recovery and resettlement over time. Drawing on social science literature relating to Fukushima, and disasters more widely, the article also argues it is imperative for researchers using GSV to reflect carefully on the wider socio-cultural contexts that are often not represented in the photo montage.展开更多

Qualitative interviews were conducted with four male Haitian participants who had survived the January 2010 Haiti earthquake and had worked as HST volunteers for at least 6 months. Interviews were analyzed using narrative inquiry analysis, which allows individuals to discover and disclose a deeper meaning in their experience and enables the researchers to access more detailed data. Previous research supports the claim that volunteerism provides many important psychological benefits, and the results of the present study suggest that among survivors of large-scale disasters, volunteerism is beneficial as a means of increasing psychological resilience and facilitating personal recovery. Results and themes of our analysis included a reported increase in both hope and purpose for the respondents. Findings suggest that volunteerism on the part of members of the surviving community following large-scale disaster increases resilience among the volunteers and further contributes to their recovery.展开更多
