Kalina Zafirova completed her final year of secondary education at the National Cultural Educational Complex, Lyceum for the Study of Italian Language and Culture, in June 2020. She has been a youth activist participating in environmental and human rights initiatives. She is also involved in theater, playing monthly at the Russian Cultural Center. She devotes much of her time to preparing and implementing actions on social causes including equality, intercultural communication, eco-social justice, self-organisation and self-government of civic structures.
In November 2016, Kalina became one of the first activists of the Bulgarian branch of the Food Not Bombs movement, which aims to fight against social inequalities, building a solidarity space for mutual assistance between disadvantaged people. Since 2018, she has been working on the Youth for Understanding “Colored glasses”, organising workshops to challenge stereotypical intercultural communication. The programme is distributed free of charge in Bulgarian schools, developing students’ competence in topics such as discrimination, prejudice, human rights, culture and ideology. The workshops are conducted in an authority-free environment in the form of games and simulations.
In March 2019, Kalina published an essay about far-right organisations in Bulgaria and the ways in which they take advantage of patriotic sentiments to instill hatred. Later that month, she took over the organisation of the Fridays for Future climate strikes. In August 2019, Kalina cofounded Violetki, a feminist art group whose creative activities set themselves the task of reflecting the eco-social reality, focusing on the empowerment of women and the LGBT+ community. In September 2019, Kalina participated in the self-government of a dormitory in Florence, which aimed to provide a space protected from sexism and xenophobia to university students, where they can study, live and develop freely. The space is self-sustaining, with income from cultural events and political lectures led by the students themselves.
