This book introduces a pathbreaking approach called ‘Avoidable Disaster Deaths’ (ADD) to reduce disaster deaths. Disaster deaths are the direct and indirect impact of hazards. The ‘Sendai Framework for Disaster Risk Reduction’ has urged the United Nations Member States to reduce disaster deaths or mortality by 2030. Reducing the number of disaster deaths has become a useful marker for improving disaster risk management. Equally important is knowing how people die, who dies, why they die, and which disaster deaths are ‘avoidable’ and ‘unavoidable’. Disaster risk reduction specialists have not fully examined these questions.
