The COVID-19 health crisis was not the first crisis, and will not be the last, whether at a regional, country or even global level. The Caribbean and Reunion are hit each year by Hurricanes / Cyclones of more or less strong intensities (cf. Hurricane Maria and Irma, Cyclone Dumile), Europe and the Caribbean are affected by earthquakes, floods, storms, heat waves... and these risks are not about to diminish with climate change, quite the contrary (“Climate change constitutes a major new threat to public health. Climate variability and its warming cause death and disease through the natural disasters they cause – such as heat waves, floods and droughts.” - World Health Organization). Faced with the scale of the COVID-19 health crisis, two points have been highlighted by the European and local youth organizations with which D'Antilles et D'Ailleurs collaborates: 1) Solidarity between youth structures in order to support and help each other and exchange tools. On this point in particular, during the crisis, DA&DA had several exchanges with various partners in order to find the best solutions to accompany and support young people currently on the move (reception or sending). 2) This crisis and the exchanges carried out with various youth organizations in Martinique, in the Caribbean and in Europe have demonstrated the needs of these structures in terms of acquiring tools, methods, sharing experiences and creating a network of crisis management support and advice organisations. The objective of the “Expect the unexpected” training course was to develop and equip youth workers with knowledge and effective tools for managing crisis situations during European youth projects linked to mobility. More specificly: - Have in each partner organization a person (ambassador) trained in the management of crisis situations (qualified in first aid techniques, risk assessment, support for young people, etc.). - Allow youth workers to share good practices, challenges and experiences in managing young people in crisis. - Develop a guide for youth organizations working in mobility giving advice and proposing different methods for monitoring volunteers, administrative points to monitor, stress management, evaluation of risks and what to do. - Analyze the contexts and risks faced by young people during mobility projects; - Improve the skills of youth workers as part of their mission of support and accompaniment young people, especially during crisis situations; - Develop the knowledge of youth actors on the specificities, administrative in particular of European youth programs; - Create concrete and lasting partnerships allowing the creation of a network of youth organizations for the support and support and exchange of experiences and best practices, particularly in crisis situations; - Discuss tools and methods to develop the resilience of young people and youth workers.
