ALNAP's Review of Humanitarian Action series (formerly known as the Annual Review) forms part of its broader efforts to support and improve learning and accountability within the international humanitarian system. The series aims to provide a means to reflect on performance across the sector by raising awareness of evaluation findings, and assessing the quality of recent evaluations, while also seeking to analyse and report on performance-related issues. This year the Review includes an analysis of learning by workers in the field, a synthesis of recent evaluation findings, with case studies of humanitarian work in Southern Africa and Afghanistan, and a meta-evaluation of humanitarian evaluation quality, with sections on good practice.
