​We outline a comprehensive approach for developing a cross-sectoral, multi-dimensional and dynamic understanding of resilience. This underpins the core message of the Sustainable Development Goals (SDGs) that development is multi-faceted and the achievement of many of the individual development goals is dependent on the accomplishment of other goals. It also acknowledges that shocks and stresses can reverse years of development gains and efforts to eradicate poverty by 2030. Crucially, this approach to understanding resilience draws on data that countries will collect for the SDGs anyway and entails only a small additional burden in this regard.​
