Understanding the importance of verification
Verification is an essential element of arms control and disarmament processes. It creates the necessary confidence that obligations and commitments are being observed. While not an end in itself, effective verification is indispensable for achieving and maintaining a world free of nuclear weapons.
To support efforts in advancing nuclear disarmament, UNIDIR’s Nuclear Disarmament Verification Repository (NDVR) is a dedicated knowledge hub, consolidating insights on verification from past and present arms control and disarmament processes.
Drawing on a range of verification practices across nuclear and related areas – including chemical, biological, conventional, and space – the NDVR provides policymakers, practitioners, and researchers with resources to inform options for current and future nuclear disarmament verification efforts.
