This paper attempts to deepen understanding and to strengthen and further develop in UK government SSR programmes policies and programmes in relation to conflict prevention. The first part of the paper examines what are the links between SSR and conflict prevention. The second part examines the regional approaches for addressing SSR. The extent to which it is appropriate to develop specific regional or sub-regional SSR approaches is considered, followed by a brief review of SSR challenges in each region and a discussion of the scope for developing and using regional mechanisms. The paper concludes with some key issues and priorities that arise for UK SSR policy.
