With this project youth organisations from the UK, Portugal, Lithuania and Italy created a sustainable network of partner youth organisations who collaborated in order to spread, support, reinforce and advocate for the concept of youth social entrepreneurship as a means of sustainable development on local and European level. These organisations and their representatives worked as the initiators and multipliers of social entrepreneurship initiatives among the youth they work with - young people from deprived urban areas. The 12 day Youth Exchange brought together peer youth leaders from the UK, Lithuania, Italy and Portugal to Porto, Portugal from the 8th to 19th April, 2016 to achieve this aim. As a result of the project, the following objectives were reached: - to respond to the challenges faced by young people from deprived urban areas through promotion of youth social entrepreneurship initiatives; - to promote and support youth social entrepreneurship on local and European level; - to create a strong and sustainable network of cooperating youth organisations; - to identify, present and multiply good practice examples of youth social entrepreneurship promotion initiatives; - to understand the approach and principles of social entrepreneurship support and recognition; - to enable young people to understand that they can contribute to the solution of social challenges faced by young people from deprived urban areas; - to increase the knowledge, skills and capacities of the partners to continue supporting young social entrepreneurs after the end of the project. At the Exchange the peer youth leaders gained skills and knowledge that they further multiplied to other youth groups in their environment. They presented what they had learned to their peers, explained what impact the project had on them, how it changed their vision of the world, and persuaded other people to take part in similar activities. The Youth Exchange included the full range of non-formal educational methods. It consisted of activities, workshops, presentations, facilitated exchange of experiences and best practices. Methods of facilitation were selected by the preparatory team from the SALTO online toolbox. The advantages gained and skills acquired at the Exchange were also disseminated to local youth groups and the organisations, which related this project to a local and European context.
