The “Disaster Pressure and Release Model” also known as the disaster “Crunch Model”, helps practitioners to understand and react to people’s vulnerability to disasters. The current Guidelines introduce new elements into the ‘Crunch Model’ so that it is able to take into consideration how women and men experience different levels and types of vulnerability to disasters. This booklet is intended for practitioners and researchers engaged in disaster risk reduction (DRR) work in the context of a changing climate.
