This research was commissioned on the occasion of the 2017 High-level Political Forum (HLPF) in New York to investigate how far the global commitment to disability has translated into implementation, monitoring and reporting processes at national and sub-national level. Four case studies were commissioned, exploring the extent of disability inclusion in alignment with the SDGs in Bangladesh, Kenya, Sierra Leone and Zambia. DPOs played a pivotal role in the research, with more than 40 DPOs consulted through key informant interviews and focus group discussions. In Zambia, the research was implemented by a local DPO – the Zambia Federation of Disability Organisations (ZAFOD). A literature review identified internet-based policy, legal and strategic documents related to disability and the 2030 Agenda, as well as documentation and reports on different SDG nationalisation initiatives.
