“Peers to Peace: Peer learning and Peer support for Capacity Building in international volunteer work” was a worldwide project that involved 25 different partners in 24 countries from Asia, Africa, Australia, and Europe. The key focus of the project was the peer approach. Through peer-learning and peer-supporting in the following areas of expertise: knowledge management, volunteer management, project management and fundraising the capacity of project partners was improved. This applied on small scale in the single events and on a large scale with upgrading the online tool for peer-support. This tool facilitates an easier access to resources and (exchange of) information and further stimulates possibilities for innovation and capacity building of project partners and International Voluntary Service movement as a whole. The project spanned over 21 months and included 3 main mobility events: a Peer university on volunteer and knowledge management in May 2017 in Poland, a Learning seminar on knowledge management and fundraising in July 2017 in Malaysia, and Training on project management in March 2018 in Greece. Besides these mobility activities, 3 capacity building events were organized as part of the project: 1) a steering team meeting in January 2017 in Germany, 2) a crucial Technical Meeting in November 2017 in the UK, as well as 3) an Evaluation meeting combined with a final event in June 2018 in Belgium. Moreover, exchange of EVS volunteers took place between Europe and Asia (3 volunteers from Asia hosted in Belgium and Greece; and 1 European volunteer hosted in Malaysia), promoting transnational non-formal learning mobility and supporting an exchange of experiences between Program and Partner Countries. The main target group of the project were youth leaders, youth workers, volunteers and activists, for a total of more than 100 people directly involved, who acted as multipliers within their sending organizations and contributed to the setting up and implementation of the peer learning system thanks to their experience. Participants came from a great variety of countries and this increased the intercultural dimension of the project and its impact, guaranteeing a real exchange and strengthening the networking capacities of the organizations. Projects results were shared among partners and within the networks they belong to. These included: 1) SCI-Moving Forward - a handbook for volunteers and staff members in SCI and partner organizations focusing on increasing the understanding of how SCI works internationally intended to support greater participation and knowledge transfer among International Volunteering Service organizations, including important chapters on finances, knowledge management and volunteering within SCI; and 2) innovative online peer- learning platform that has been newly integrated in SCI’s Members Area allowing for direct exchange of knowledge and experience among SCI members. The participation of other major IVSO networks, such as Coordinating Committee for International Voluntary Service (CCIVS), Network for Voluntary Development in Asia (NVDA), and Voluntary Workcamps Association in Nigeria (VWAN, central NGO in Africa) enriched the project with diverse inputs on volunteering and youth work in their context.
