Over the past half-century, the fragility of peace agreements has been starkly evident, with nearly 40% collapsing within five years of their inception. This alarming trend underscores the complexity and volatility inherent in post-conflict environments. However, emerging research from the University of Notre Dame offers a beacon of hope, revealing that international actor involvement during the implementation phase can significantly enhance the durability of peace accords. The crux of this research demonstrates that not just participation, but the intensity and visibility of such engagement, can serve as a linchpin for sustaining peace.
Dr. Madhav Joshi, a research professor and associate director of the Peace Accords Matrix, spearheaded this groundbreaking study, meticulously analyzing peace agreement implementation from a data-driven perspective. Published in the Journal of Intervention and Statebuilding, the study focuses on how a visible, on-the-ground presence of international stakeholders—including foreign nations, multinational organizations, and policy advocacy groups—imposes heightened reputational costs on local leaders who might otherwise renege on their commitments. This reputational deterrent compels these actors to adhere to their peace obligations, ultimately reinforcing agreement durability.
The study’s empirical backbone is constructed from real-time data drawn from the landmark 2016 peace agreement between the Colombian government and the Revolutionary Armed Forces of Colombia-People’s Army (FARC-EP). This accord stands as a paragon of international engagement, with over 30 global entities supporting both negotiation and implementation phases. The University of Notre Dame’s Peace Accords Matrix Barometer Initiative played a pivotal role in monitoring and verifying the accord’s commitment fulfillment, marking the first instance where an academic research center has actively contributed to peace agreement implementation on such a direct and sustained level.
Utilizing a comprehensive dataset comprising 578 discrete commitments tracked from December 2016 to April 2023, Joshi’s study provides irrefutable evidence that international involvement and the depth of this engagement correlate positively with effective implementation outcomes. These findings challenge earlier notions that primarily emphasized domestic political variables as determinants of success or failure. While it is well-established that internal political costs and fluctuating domestic support often derail peace processes, Joshi underscores how international partners bring both essential expertise and critical resources to bear on the elements of peace agreements most vulnerable to breakdown.
Moreover, the heightened visibility generated by international oversight is instrumental in upholding peace accords. The global spotlight raises the stakes for domestic actors, fostering a sense of accountability and deterring leaders from capitulating to short-term political incentives or plunging back into conflict. This dynamic is particularly salient in Colombia, where despite President Iván Duque’s initial opposition to the peace deal during his 2018 campaign, extensive international involvement constrained his ability to abandon the commitments enshrined in the accord without incurring significant reputational damage.
The implications of Joshi’s research extend well beyond the Colombian case study. It offers a data-informed template for policymakers and practitioners operating in post-conflict contexts worldwide. By incorporating and institutionalizing international partners into peace strategies from the outset, negotiators can embed protective mechanisms that maximize the probability of successful implementation. The study advocates for the proactive deployment of international support immediately following agreement signing to capitalize on the momentum and to mitigate early-stage implementation risks.
This research also connects to broader scholarly discourses on the pathways to sustainable peace. Building upon Joshi’s earlier work on partial peace agreements and the integration of gender considerations, this latest study enriches our understanding of the multifaceted factors that influence peace durability. The Peace Accords Matrix continues to be an unparalleled repository of empirical data, fostering evidence-based policy design and enabling a rigorous evaluation of peace processes worldwide.
Such findings are especially pertinent in an era marked by resurgent global conflicts and the evolving nature of international cooperation. They underscore the necessity for a paradigm shift in how peace agreements are operationalized—from isolated, national endeavors to globally supported, meticulously monitored processes. This shift not only leverages international expertise but also harnesses the power of reputational dynamics on the world stage, producing a potent deterrent against non-compliance.
Furthermore, the study illuminates a critical mechanism by which peace implementation can resist domestic political turbulence. International actors serve as both technical facilitators, providing vital resources and expert guidance, and as normative enforcers, with their involvement increasing the political costs of non-implementation. This dual role strengthens the resilience of peace agreements, especially in contexts where domestic political will is fragile or contested.
Dr. Joshi’s evidence-based approach challenges traditional perspectives that view peace agreements primarily through the lens of domestic political will or coercion. By demonstrating how strategic international accompaniment influences leader behavior, the research advocates for a more nuanced understanding of peacebuilding as an inherently international endeavor. This reconceptualization positions global actors not merely as external observers but as integral partners in the complex architecture of peace implementation.
In sum, the University of Notre Dame study dismantles complacency surrounding peace agreement durability and provides a scientifically grounded framework for enhancing post-conflict peacebuilding. By leveraging the reputational costs imposed by active international engagement, peace accords stand a substantially improved chance of moving from paper agreements to tangible, lasting peace—transforming conflict zones into arenas of stability and reconstruction.
