The project Soli Mai! arises from the need to understand where the integration of social and health services are in the event of natural disasters. From the analysis performed, a serious condition of environmental emergency is detected, with risks especially for the health of the affected population. The key objectives of the project are: helping to prevent, supporting and dealing the needs; using civil and respectful behaviours for social welfare; verifying the new ‘social constructs’, taking into account both the conditions of the society and cultural elements available to a community to interpret events and circumstances; valorization of social networks and mutual aid; recovery of con dence both in individuals and in the institutions to avoid the sense of abandonment. Hence, the main assumption, common to all the de nitions, is that a disaster always implies a discontinuity of the social context, in which individuals and social structures have worked up to its occurrence, and a departure from the pattern of daily expectations shared by a community. The guidelines or steps to be taken into account both ex-ante and ex-post in a natural disaster are: forecasting; prevention; warning, pre-alarm, alarm, managing the emergency; restoration of normality. Only by working at various levels on different aspects of the system (preparatory courses and primary prevention for most subjects, assumption of responsibility by several organizations, trust, respect and collaboration between the institutions and the population, a taking in charge no longer based on the symptoms but based on social solidarity) it will be possible transition from a catastrophe to a perspective of prevention.
