The African Centre for Biodiversity (ACB) welcomes you to our website. We are a research and advocacy organisation working towards food sovereignty and agro-ecology in Africa, with a focus on biosafety, seed systems and agricultural biodiversity. The organisation is committed to dismantling inequalities and resisting corporate-industrial expansion in Africa's food and agriculture systems.

Agroecology as an alternative (Video four of a four-part series)


In August 2018, the Rural Women’s Assembly (RWA) and the African Centre for Biodiversity (ACB) hosted a speak-out for SADC smallholder farmers in Windhoek, Namibia, on Farm Input Subsidy Programmes (FISPs).

FISPs are government agricultural programmes that promote Green Revolution inputs produced by multinational corporations, such as chemical fertilizers. In Ghana, for example, up to 47% of the agricultural budget is spent on fertilizer subsidies.

But the top-down FISP packages do not support holistic farming practices. To address this, in Ghana CSOs and farmers have come together to form an agroecology network. At regional level they are creating hubs for farmer-to-farmer training and at national level the network is mobilising for the FISP to be expanded to include support for agroecological farming methods.

Production quality controls in farmer seed systems in Africa


This ACB report explores issues relating to farmers’ independent seed development, production and distribution. Drawing from innovative case studies in Brazil, East Africa and elsewhere, suggestions are presented to strengthen farmer quality control practices.

In sub-Saharan Africa, more than 65% of the population depends on agriculture for their livelihoods, producing around 80% of food consumed. Smallholder farmers on the continent source more than 90% of their seed from their own saving, relatives and neighbours, and local markets, and less than 10% from the formal seed sector.

Smallholder farmers play a critical role in maintaining, adapting and using agricultural biodiversity, as recognised in the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) and elsewhere.
