Localized Ceasefires: Lessons from the OSCE Engagement in Ukraine, 2014–2022

This paper explores the underexamined role of localized ceasefires facilitated by the OSCE Special Monitoring Mission (SMM) to Ukraine between 2014 and 2022. While not part of the Mission’s original mandate, these localized arrangements became critical tools for enabling humanitarian access and infrastructure repairs amid ongoing hostilities. Drawing on field experience and operational data, the paper analyzes the SMM’s efforts to negotiate temporary truces, the challenges posed by the expansion of the Mission’s tasks, and its constrained ability to assign responsibility for ceasefire violations. It argues that localized ceasefires, despite their ad hoc nature, offer valuable lessons for future missions in protracted conflict settings. The paper concludes with policy-oriented recommendations to institutionalize localized ceasefire mechanisms, enhance local ownership, and ensure the strategic integration of field-level innovations into broader peacebuilding efforts.
