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.



Improving early warning system capacity in least developed countries and small island developing states

In least developed countries (LDCs) and small island developing states (SIDS), increasing numbers of people are at risk of losing their lives as a result of weather- and climate-related hazardous events. This trend can, in part, be attributed to a low or basic capacity to use risk information and to provide early warning. LDCs and SIDS are prioritising improvements to early warning systems for climate change adaptation, as reflected in their Nationally Determined Contributions to the United Nations Framework Convention on Climate Change. Although investment to strengthen climate services has increased, these countries’ funding needs remain unmet. Closing the funding gap requires building on existing investments, leveraging additional funds, and improving effectiveness.
