The Link association manages the community library, a regenerated space in one of the most problematic neighborhood of the city thanks to funding from the Puglia Region. Many of the young people in the neighborhood are at risk of social exclusion and deviance; the community library plays the role of promoting culture and participation, and has started a dialogue through a series of activities ranging from cineforum to garden care, through courses of language and art workshops. The library is bordered by a huge concrete wall, so the idea of creating an international youth exchange emerged, with the aim of creating a large collective mural that gives color and, at the same time, transmits a message of current relevance and currently strong interest for young people: climate change. The project meets the objectives of Erasmus + in terms of learning, creating an opportunity to express creativity, to acquire new skills, to stimulate participation in the democratic life of society. Moreover, being a project with young people with fewer opportunities, it will promote social inclusion.
