Practitioners and researchers in Child-Centred Disaster Risk Reduction (CCDRR) and school safety seek to safeguard the threats to children’s rights and help alleviate the suffering caused by hazard and risk impacts of all kinds. They work towards achieving impact, at scale. Over the last 15 years there has been substantial growth in research on the role of children and children’s education in Disaster Risk Reduction (DRR). Despite this attention, however, there has been limited in-depth attention within CCDRR to understand scaling up and what makes initiatives effective for scale-up. This research sets out to address this critical gap in CCDRR and to strengthen the capacity of effectively scaling up CCDRR initiatives, including Comprehensive School Safety (CSS).
