This review is the result of a collaboration between Elrha, the London School of Hygiene and Tropical Medicine (LSHTM) and the Sphere Project. Funded by DIFD and the Wellcome Trust, The Research for Health in Humanitarian Crises (R2HC) programme commissioned LSHTM to conduct a review of the evidence supporting the Sphere standards. This report contributes to the 2018 revision of the Sphere Handbook by providing rigorous analysis of existing evidence and supporting the production of new empirical evidence where appropriate.
