In episode five of the systems’ mapping, building blocks approach, we continue to explore the topic of registration. This time, we look closely at the Cambodian IDPoor programme, to understand to what extent a government-led effort to improve how beneficiaries of social assistance and social protection schemes are effectively accounted for – and what are the gaps, challenges and merits of this new registration drive. To understand the Cambodian case, we invited Bunly Than. Bunly is the lead of the Inclusive and shock-responsive social protection system project at Oxfam Cambodia. *Our theme music is Focus from AA Aalto (Creative Commons) References WIEGO Resource Document #30 (2023).
