Salvatore Fallica (IHS) has just returned from his four-week secondment to the Southern Denmark University (SDU). He spent an intense month of knowledge exchange, lectures and travels around Skandinavian universities, incubators and social enterprises under the excellent coordination of Professor Thomas Persson. Salvatore retrospectively evaluates his stay as a fundamental experience that marks the beginning of stronger collaborations between actors or social innovation ecosystems from Skandinavia to Sicily.
