Demeter PGS SA

Demeter Participatory Guarantee System Southern Africa

BDAASA is committed to cultivating co-operation amongst biodynamic farmers and the community.

One of the initiatives to achieve this goal is the implementation of a Participatory Guarantee System.

Participatory Guarantee Systems (PGS) are locally focused quality assurance systems where producers evaluate each other. The system is based on the active participation of stakeholders and is built on a foundation of trust, social networking and knowledge exchange.

Because BDAASA holds the Demeter standards as its benchmark for biodynamic agriculture, the BDAASA Demeter PGS programme is aligned with BFDI (Biodynamic Federation Demeter International) who will accredit the Demeter PGS SA and allow the use of the International Demeter trademark for local sale of Demeter PGS certified produce.



Farmers interested in joining Demeter PGS SA should contact the BDAASA for an application interview and, by agreement, will be allocated to an existing Demeter PGS SA Farm Unit, or if a group does not exist in the area of the farm, be assisted to establish a Demeter PGS Farm Unit.
