The article discusses how local engagement can contribute to preventing or ceasing ongoing conflicts. By the comparative analysis of three case studies – Somaliland, the Idjwi island in eastern Congo and Colombia, the author examines what methods do the local inhabitants use in order to successfully maintain peace and build a coherent society. The research on a bottom-up approach may supplement the strategies implemented by the international organisations of peace-building or peace-keeping missions, which usually neglect the engagement of local society and thus do not ensure sustainable peace.
