This educational video presents Participatory Guarantee Systems (PGS) through practical examples and theory. It is illustrated by 4 PGS initiatives: “Nature et Progres” in France, “Rede Ecovida de Agroecologia” in Brazil, “Bryanston Organic and Natural Market” in South Africa and “Sabeto Organic Producers Association” in Fiji. The video is structured to show why and how PGS are set up as well as the benefits that derive from PGS to all stakeholders. It provides an inspiration for all who are interested in Organic Agriculture, small farmers and local market development, including: farmers, consumers, NGO staff, extension workers, universities and other educational centres.
