Survey on the knowledge, use, structure and content of the Sphere handbook

This survey is the result of a collaboration between Elrha, the London School of Hygiene and Tropical Medicine (LSHTM) and the Sphere project. R2HC commissioned LSHTM to document the level of empirical evidence on which the Sphere Handbook current principles and indicators are based, and to conduct a user survey to gather feedback on the Handbook content and structure. The review and survey were conducted in close collaboration with the Sphere Project, and have contributed to the process of the 2017 Handbook update
