Conflict poses considerable challenges for services that support communities, and in particular those affected by violence. This book describes the work undertaken in Omagh against the background of the most recent period of violent conflict in Ireland, and specifically it draws upon the work following the Omagh bombing. The bombing came just four months after the Northern Ireland peace agreement, known formally as the Belfast Agreement of 1998, and more informally as the Good Friday Agreement. The book describes the impact of the bomb and the early responses. Local trade unions, employers and the business community played key roles at times, particularly in underlining the need for solidarity and in identifying themselves with the desire for peace. The book looks at the outcome of needs-assessments undertaken following the Omagh bombing. The efforts to understand the mental health and related impact of the violence associated with the Troubles in Northern Ireland over the period 1969 to 2015 are focused in detail. The later efforts to build services for the benefit of the wider population are described, drawing upon the lessons gained in responding to the Omagh bombing. The developments in therapy, in training and education, and in research and advocacy are described with reference to the work of the Northern Ireland Centre for Trauma and Transformation (NICTT). The book draws together key conclusions about the approaches that could be taken to address mental health and well-being as an essential component of a peace-building project.
