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
