PGS SA and SAOSO form the South African node of the Knowledge Hub for Organic Agriculture in Southern Africa (KHSA). KHSA is part of the Knowledge Centre for Organic Agriculture in Africa (KCOA) project, which is a collaborative country-led partnership funded by the German Federal Ministry of Economic Cooperation and Development (BMZ) and implemented by the Deutsche GesellschaftfürInternationaleZusammenarbeit (GIZ) GmbH and non-governmental organisations. The South African-based Sustainability Institute supports project implementation in the region.

KCOA aims to scale up adoption of organic farming practices in Africa over a four-year period. In Southern Africa, KHSA focuses project activities in Zambia, led by Participatory Ecological Land Use Management (PELUM) Zambia; in Namibia, led by the Namibia Nature Foundation in collaboration with the Namibian Organic Association; and in South Africa, led by SAOSO. GIZ is also implementing this project in north, east, west and central Africa.
