Participatory Guarantee System (PGS) is a low-cost quality assurance mechanism that guarantees the quality of agricultural products and has the potential to regain consumers’ trust. Implemented in 66 countries worldwide, it has been used in Vietnam for over 10 years. As part of the project Capitalisation of Participatory Guarantee System experiences in Vietnam for upscaling, institutionalisation€, Vietnam National University of Agriculture and Rikolto investigated all the existing PGS in Vietnam to assess their strengths and weaknesses and come up with recommendations on how to improve PGS in the Vietnamese context. This case study investigates the factors that made PGS Thanh Xuan the most successful PGS model in Vietnam and identifies some of the features that should be replicated by other PGS to improve their sustainability
