Despite significant attention and interest in shock-responsive social protection, a knowledge gap exists when it comes to our understanding of how to sustain capacity to deliver existing social programmes and systems in situations of climate and/or conflict crisis. BASIC Research is using a new tool that we have developed – the Capacity Cube – to explore this question and identify ways in which external actors might support the resilience of those systems and programmes. An explanation of the Capacity Cube framework is provided in an accompanying briefing (Slater 2024). The current briefing focuses on early findings emerging from research using the tool in Nigeria, Iraq, and Syria.
