Disarmament, demobilization, and reintegration in peace agreements (1975–2021): Introducing the DDR dataset

Disarmament, demobilization, and reintegration (DDR) provisions in peace agreements (PAs) are critical pillars of global peacebuilding efforts. Leading theories suggest that different DDR components address different peacebuilding challenges. Yet existing datasets conceptualize DDR as a binary variable, hindering our ability to observe which DDR components and in what combination are agreed upon by conflict parties and to assess their independent effects on peace. To address this problem, we introduce a global disaggregated dataset on DDR provisions in PAs from 1975 to 2021, identify third-party actors’ involvement, and whether women and children ex-combatants are referenced in the provisions. We show that DDR components do not always come together: 47% of all PAs contain at least one DDR component, but only 26.9% include the full DDR package. Moreover, third-party actors participate in more than half of PAs with at least one DDR provision, and the vast majority of DDR provisions do not reference women and child ex-combatants. We demonstrate the usefulness of our dataset by analyzing the determinants of DDR provisions in PAs. Our analysis shows that different covariates have different effects on different DDR constellations, highlighting the usefulness of our disaggregated approach. The DDR dataset can be a valuable source to better understand the processes, causes, and consequences of DDR provisions.
