This publication highlights major trends in the nature of humanitarian crises, their underlying causes and drivers, and the actors that participate in prevention, response and recovery. Beyond providing statistics, the report uses infographics to display trend analyses that show how the humanitarian landscape is evolving and how the humanitarian system can be more effective. Data in the report come from a variety of sources and partners. The report provides an overview of the humanitarian landscape in terms of funding, capacity, crises and appeals; a 'regional perspectives' section and 'trends, challenges and opportunities' section, which provides a case study on issues that impact humanitarian operations. Highlights for 2017 include new case studies on explosive weapons, humanitarian and development financing in protracted crises, and sexual and reproductive health in emergencies.
