In a record of increasing cases of natural disasters and humanitarian crisis, the need arises to establish a group of volunteer solidarity workers who will appear in a second year, relieving the immediate rescuers and supporting the affected, with nutritional, pharmaceutical and psychological coverage, the latter through the addition of street theater. The research begins in the region of Thessaly, which is plagued by flooding phenomena, showing the accelerating climate disaster. It finds correspondences in the course of the volunteer corps with the wandering theatre troupes, in order to ultimately combine their accommodation practices, so as to enrich and renew their mechanisms of movement and provision of assistance, to add to their services the mental stimulation, through collective design and reuse, the language of theatre, which was the only cultural element that survived in the most difficult situations, and finally to create a network of communication and unity between the volunteers, and the affected people of each area. In this work, the Pelion region is analyzed and in particular the village of Kato Lechonia, which was flooded twice in September 2022. For the needs of the volunteer group, the proposal includes the redesigned transport vans of the volunteers, along with their equipment, a wheeled construction for distributing goods and collecting waste, and a series of objects, the result of collaborative design. and transformation of volunteers with the residents, aiming to use them in the theatrical works that will be presented. The solidarists meet the Balkan ‘bouloukia’ and the ’Theatre du Soleil’, using mechanisms and systems of organization of the troupes, to create this special group.
