This scholarly work is no doubt a very useful material to students and all persons desirous to acquire sound knowledge and understanding of the topical issues of disarmament, demobilisation and reintegration ----OSEMENE, Goodluck James Registrar, Temple Gate Polytechnic, Aba. DDR programmes are significant in actualisation of sustainable peace in every post-conflict society. Apart from context dynamics of DDR programmes, this book offers cross learning. The need for peace and stability occasioned the DDR programmes in Niger Delta and Sierra Leone. The socio-political instability that scarred Sierra Leone for a decade and Niger Delta which intensified in Nigeria’s Fourth Republic necessitated governments’ intervention in both countries. This book examined the disarmament, demobilisation and reintegration modelling in Nigeria and Sierra Leone which were designed to contain armed conflicts and remove arms from the wrong hands. Through this comparative study, students, scholars and researchers will be acquainted with the similarities, differences, significance and the outcomes of the DDR programmes in Nigeria and Sierra Leone, being ECOWAS member states --- James Okolie-Osemene.
