We have created this guide to help you make best use of research evidence when you are in a humanitarian emergency or when you are planning for the next emergency. Our intention is to help you find and use evidence on interventions, actions and strategies that might help you make informed choices and decisions. This guide is not about how to generate more research evidence. It is about using and understanding what evidence exists and recognising when good evidence is lacking. It should help you build your confidence in compiling, assimilating, distilling, and interpreting a strong evidence base of existing research, and think about how you might go on to evaluate your own projects and commission research or evaluation.
