In 2010, in Rosarno, after the last attack against immigrants working in the fields, the latter started a protest that became a real warfare. The responsibilities rebounded on the little local producers, which in turn reveal themselves like victims of the economic system. In this contest takes place the project "SOS Rosarno" that has a special political responsibility acting on an economic level. They bring to life to a "solidarity economy form" through a GAS; the idea is to create an instrument that can carve out a space of fight. The instrument that can take a route of change is the creation of group of little producers that together choose to separate themselves from market logic. In this paper we want to consider the Solidarity Economy way like a new self-defense society form.
