By boosting the potential of social entrepreneurship in those sectors through sharing economy by means of an integrated multi-scalar methodology and practice, the project will lead to reducing economic disparities and increasing social integration. Many of the Mediterranean EEA regions, in addition to unemployment and inactive young population between 25- 29 skyrocketing, face special socio-environmental insularity-related pressures, the refugee crisis, lack of coordination between actors and interventions, and absence of personalized support. Such a poly-parametric problem needs transnational cooperation, coordinated research and new empirically-grounded solutions based on know-how transfer, in order to cover three needs: i) to train properly selected groups (especially inactive low-skilled women and migrants familiar with the Mediterranean culture) in locally resilient sectors, ii) to enhance employability in a transferable way by advancing knowledge and skills through social entrepreneurship and innovative peer-to-peer platforms connected to niche markets, and iii) to establish long-lasting labour market engagement by involving various, mostly non-traditional, stakeholders and through innovative research and path-breaking Employment Centres.
