Advocating is probably the most cost-effective type of action NGOs can carry on, since their effects are lasting for years (generations, even). Advocacy is also a valid way to improve society and support those in need, including youth. The reason behind this activity, postponed for one year due to the pandemic, is still relevant when the global health crisis is decreasing and other crises arise, is that young people can achieve an amazing impact on society through successful advocating - if they believe in a cause, in themselves and have a specific set of competences, that we explored and learned about in this one-week seminar. Through advocating, young people can create social awareness about some of the most urgent global challenges, including global health, climate crisis, war culture, refugee crisis, xenophobia, human rights, SDGs, and others in a context that is much worse now than only one year ago, when the activity was expected. The seminar promoted the idea that every not-for-profit non-governmental youth organization can influence policymakers to the extent they are capable to encourage and support young people to act as advocates and leading the changes which are necessary, in each community and at European and global level. The 4 general objectives of the seminar were: - To understand advocacy as part of our role as youth NGOs. -To learn how to encourage and support young people to take leadership as advocates. -To focus on the knowledge, skills, and attitudes which are necessary to advocate successfully and collect valid tools and activities to develop and recognize advocating as a competence. -To promote exchange and networking among youth workers and NGOs active in the field of non-formal and intercultural learning, volunteering, active social inclusion, and youth empowerment at the European level. The 4 specific objectives were: -To share inspiring stories, practices, and experiences, successful or not about advocacy actions done by promoter organizations at local, regional, national, European, and international levels. -To define together a competence framework ‘for young people to take leadership as advocates’ we can use on each promoter organizations. -To encourage participants to develop 4 key competencies as advocates during the activity. -To learn how to design, implement and evaluate a campaign, both online and offline.
