Worldwide, there are now 100 million displaced people, often living among host communities on a protracted basis. To respond to this growing and evolving challenge, there is increasing interest in the role that national social protection systems can play in supporting those affected by forced displacement. This has created a need to better understand when and how humanitarian assistance can effectively link with social protection systems to serve displacement-affected populations. To start to fill this knowledge gap, an ODI-led consortium was commissioned to undertake a research project on this topic from 2020-2022. One of the principal outputs of this project is the development of an analytical framework that can be used to explore the potential approaches for linking humanitarian assistance and social protection systems in a given displacement context.
