The first section provides an accessible introduction that explains what ‘wellbeing, and ‘ Quality of Life, have come to mean in international development, and why they have become important concepts to policy makers. It defines key concepts and suggests questions and choices that policymakers and practitioners must consider when deciding to adopt a wellbeing or QoL approach in their programming. The main part of the book presents different frameworks and tools that have been developed and used in measuring wellbeing and QoL, assessing the impact of programmes, and how a wellbeing approach can be used in policy and advocacy. The chapters discuss the impetus for adopting a particular approach, describe how the specific frameworks and tools work and reflect on the strengths and limitations of the approach as well as lessons learnt in implementing it.
