This important book presents impactful findings from twelve international longitudinal studies that responded to the Agenda 2030 commitment to "leave no-one behind". Exploring a wide range and complexity of global issues, it provides actionable strategies for policy makers and practitioners to strengthen the global Sustainable Development Goals framework and accelerate their implementation.
