Extending impact study: a practical review

Catholic Relief Services’ 2015 study, Extending Impact: Factors influencing households to adopt hazard‑resistant construction practices in post‑disaster settings (EI), explored the factors that contribute to people’s independent decisions to use hazard‑resistant reconstruction practices after a disaster, and aimed to increase the scale and impact of shelter interventions by guiding the design of humanitarian projects. 

Through this review, CRS aims to provide a snapshot of the application of the EI recommendations by field practitioners and researchers in the shelter and settlements community, observe which recommendations they saw as being applied most frequently and why, and gain an insight into why some were not being used. The review also includes recommendations that those EI elements cited as most important for increasing resilience be strengthened.
