Established in January 2022 uBumi PGS is a Participatory Guarantee System, as defined by IFOAM, it is "a locally focused quality assurance system. PGS certify organic producers based on the active participation of stakeholders and are built on a foundation of trust, social networks and knowledge exchange." They represent an alternative to third-party organic certification, specially adapted to local markets and short supply chains. They can also complement third-party certification with a private label that brings additional guarantees and transparency.
