How UN peacekeeping missions enforce peace agreements

How do UN peacekeeping missions enforce peace agreements, and what effect do higher rates of enforcement have on agreement implementation and conflict termination? Peace agreement enforcement forms a central component of peacekeeping effectiveness, yet missions are often mandated to enforce a minority of agreement provisions, and they vary across both time and space in the ways in which they do so. I identify the three dimensions along which enforcement operates—the proportion and type of provisions that missions are mandated to enforce, alongside their mandated level of involvement in their implementation—and theorize about their positive effects on agreement implementation and conflict termination. Analyzing the Peacekeeping Enforcement Dataset, an original data set of the enforcement patterns of all UN peacekeeping missions (1989–2015), I find that each dimension of enforcement has, at various time points, a distinct impact on agreement implementation and preventing conflict recidivism.
