Participatory Guarantee Systems (PGS) and short organic supply chains have emerged as promising solutions for smallholder farmers to provide organic produce to nearby consumers. PGS is an institutional innovation that builds trust among producers, traders and consumers through a low-cost transparent and participatory certification mechanism. They have particularly gained a foothold among smallholder farmers in middle- income countries, where third-party certification costs are often unaffordable.
L’approche Champs-Écoles Producteurs (CEP) est introduite au Ghana en 1996, au Niger en 1999 et au Sénégal en 2000 via le projet « Gestion intégrée de la Production et des Déprédateurs (GIPD) » soutenu par la FAO.
