This 66th issue of Participatory Learning and Action (PLA) includes general articles on participatory approaches to development submitted by readers and explores the links between participation, sustainable natural resource management and improving livelihoods. It also includes a selection of other articles, including how urban community groups in Chile have opposed two urban redevelopment projects; the use of participatory impact assessment tools to define, measure, monitor, review and analyse progress; and a discussion of ethical issues and standards for participatory work. There are also reflections from members of the international Resource Centres for Participatory Learning and Action (RCPLA) network, a foreword from IIED’s Camilla Toulmin and reflections from Robert Chambers of the Institute of Development Studies (IDS). The PLA series was 25 years old in 2013 and at this milestone, IIED decided to take stock to look at PLA’s legacy and future direction. After this issue, the series will be put on hold, pending the findings from an external evaluation.
