80-90% of planting materials in South Asia and sub-Saharan Africa are produced on-farm
“How much of the world’s crop area is sown to farm-saved seed (FSS)? For most countries there are no official statistics, but rough estimates can often be made by comparing the sales of certified seed of a crop with the total area under cultivation with that crop. Figures compiled by GRAIN indicate that most developing countries still mainly depend on FSS – in particular regions with a large peasant farming sector, such as South Asia and sub-Saharan Africa, where typically 80–90% of planting materials are produced on-farm.”
