This joint research aimed to provide detailed longitudinal evidence of the successes, failures and lessons from previous Christian Aid (CA) and Habitat for Humanity (HFH) emergency interventions in the shelter sector, providing recommendations for the improvement of future programmes and areas for further research and collaborative work. The ultimate goal of this research is that affected households receive better quality and more appropriate, timely and cost-effective shelter assistance as well as better support for their immediate recovery and long-term resilience to future disasters. The research was undertaken by a multi-disciplinary project team including HFH, CA, Arup International Development (Arup ID) and SaferWorld Communications. The research could not have been completed without the support of our local partners: HFH Indonesia, HFH Philippines, HFH Haiti, The Church’s Auxiliary for Social Action (CASA), The Social Awareness Society for Youths (SASY), SEEDS India, SSID, GARR, Aprodema, Koral and Haiti Survie. The research included case studies in Haiti, the Philippines, India and Indonesia.
