These case studies complement the 2018 Development Co-operation Report: Joining forces to leave no one behind. Case study contributors share knowledge and lessons on what it takes to answer the pledge of the 2030 Agenda for Sustainable Development to leave no one behind through national and sub-national policies, strategies and programmes as well as international development co-operation projects, programmes and partnerships. The insights, good practices and lessons shared in these case studies were provided by diverse actors. These include official development co-operation ministries and agencies from members of the OECD and the Development Assistance Committee, international organisations, developing country governments, civil society organisations, business, and research bodies.


The case studies highlight experiences from projects and programmes in leaving no one behind and reaching the furthest behind. They are organised and presented under two broad categories:

1. Reaching and including people and places;

2. The enabling role of international co-operation: policies, partnerships and data.



Executive summary

In 2015, United Nations Member States endorsed the 2030 Agenda for Sustainable Development – a transformative global agenda integrating economic, social and environmental development within 17 interdependent Sustainable Development Goals (SDGs). Central to the 2030 Agenda is the pledge to meet these goals for all, leaving no one behind, and endeavouring to reach the furthest behind first. In spite of this commitment, growing inequalities - of income, wealth, access to basic needs in terms of food, shelter and clothing, but also to sanitation, education, healthcare, justice and human rights – are constraining the achievement of real, visible and long-lasting development. Failure to achieve leave no one behind constitutes a major stumbling block to the achievement of the entire set of global goals and their vision for a shared future as set in the 2030 Agenda.
