Synthetic Aperture Radar (SAR) remote sensing is a useful tool for mapping earthquake-induced building damage. A series of operational methodologies based on SAR data using either multi-temporal or only post-event SAR images have been developed and used to serve disaster activities. This presents a critical problem: which method is more likely to obtain reliable results and should be adopted for disaster response when both pre- and post-event SAR data are available? To explore this question, this study takes the 2016 Kumamoto earthquake as a case study. ALOS-2/PALSAR-2 SAR images were employed with a machine learning framework to quantitatively compare the performance of building damage mapping using only post-event SAR images and mapping using multi-temporal SAR images. The results show that an overall accuracy of 64.5% was achieved when only post-event SAR images were used, which is 2.3% higher than the overall accuracy when multi-temporal SAR images were used. The estimated building damage ratio for the former and the latter are 29.7% and 31.1%, respectively, which are both close to the building damage ratio obtained from an optical image.

The aim of this paper is to describe a unique, bottom-up model for building a school based on humanistic intercultural values in a post-disaster/refugee area. We think that this model will be of use in similar contexts. This single-case study can teach us about the needs of refugee children, as well as provide strategies to reach these needs with limited resources in additional similar contexts. Additionally, this paper will outline a qualitative arts-based methodology to understand and to evaluate refugee children’s lived experience of in-detention camp schools. Our field site is an afternoon school for refugee children operated and maintained by volunteers and refugee teachers. The methodology is a participatory case study using arts-based research, interviews, and observation of a school built for refugee camp children in Lesbos. Participants in this study included the whole school, from children to teachers, to volunteers and managers. The research design was used to inform the school itself, and to outline the key components found to be meaningful in making the school a positive experience. These components could be emulated by similar educational projects and used to evaluate them on an ongoing basis.
