In a tense social and economic context, characterized by high unemployment rates (especially among young people), higher social inequalities and environmental degradation, more and more people feel uncertain about the future. Their lack of perspective breeds a feeling of helplessness and often leads to isolation or rejection behaviors that undermine social cohesion as well as our ability to meet the challenges of climate change and globalization. Nevertheless, everywhere in Europe, innovative, economically viable, socially and environmentally respectful projects are emerging. These initiatives demonstrate that there are other ways to take action, act and live together, thanks to which we could cater to the fulfillment of each member of community and maintain the sustainable development of our society. Unfortunately they are still little talked about. The SustainABILITY project aims to promote them and to spread the knowledge, know-how and skills acquired by those who implement those initiatives. By reaching a wider audience, an increasing number of people will be inspired, regain confidence in the future, in their personal ability to act or develop the projects they are putting efforts into. To achieve this, we propose to train youth and social workers so that they can improve the quality of the projects they carry out and spread the knowledge and skills they acquired to the persons they support, mainly young people and people with fewer opportunities. Thus, this training course aims at strengthening the participants' knowledge, developing their professional skills, their social skills and their adaptability to situations, and at providing them a sense of self-fulfilment that will increase their motivation and satisfaction in their daily work. By empowering them, the training course aims to improve the socio-professional integration of the target groups the participants support, increase the inclusion of people in social projects and promote the emergence of social innovation projects locally. It will do our part for promoting diversity, intercultural dialogue as well as the values of justice, freedom, solidarity and protection of human rights and the environment. Finally, the network of stakeholders involved in the social and ecological transition across Europe will also be strengthened.
