    Sammanfattning : Screen media activity such as watching TV and videos, playing video games, and using social media has become a popular leisure activity for children and adolescents. The effect of screen time has been a highly debated topic; however, there is still very little known about it. LÄS MER

  2. 2. The creation of a democratic food certification : How the Slow Food Participatory Guarantee System attempts to defend local food systems and traditions

    Master-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Greta Borrelli; [2021]
    Nyckelord :Participatory Guarantee System; Food certifications; Food standards; Organic movement; Organic certification; Slow Food; Presidia project; Biocultural heritage; Food heritage; Traditional food knowledge; Governmentality; Empowerment;

    Sammanfattning : This thesis explores if and how an alternative certification system for agricultural products, the Participatory Guarantee System (PGS), could support small-scale farmers to preserve and promote biocultural and food heritage, linked to the landscape they inhabit, their identity as farmers and traditional knowledge. The PGS has been identified by Slow Food as an efficient low-cost and local 'bottom-up' quality assurance system, in order to develop their Presidia project and to re-embed agricultural productions within their traditional socio-ecological contexts.
