The book is divided into three parts: Part 1 provides an outline of the three phases of critical realism: original/basic critical realism, dialectical critical realism and the philosophy of metaReality. Part 2 presents a case study that applied critical realism as a research-theory framework. The case study explores the formation of the Somali Community Organisations in the UK and develops a retroductive model that outlines their role in engaging the Somali Diaspora Community with the issue of sustainability. Part 3 presents reflections towards the geo-historical study of Somalia and explains the origins of the civil war and the dispersal that resulted in the formation of Somali Diaspora Communities in different parts of the world. This book will be of interest to Critical Realists, researchers on and in Africa, agencies interested in Somali affairs, researchers on diaspora and refugees, Somali Community Co-ordinators and local council authorities in the UK and Europe.
