There are also specific programmes that target small-scale agriculture, with some purchases being distributed via food programmes. They are announced regionally through the PGPM (Politica de Garantia de Pregos Minimos) by the Secretary of Agricultural Policy (SPA) operated by the National Food Supply Agency (Companhia Nacional de Abastecimento, CONAB). This mechanism covers a great variety of crops from rice, wheat, maize, cotton, soybeans, to regional crops like cassava, beans, agai, guarana, sisal, and a few livestock products like cow and goat milk, and honey. Other price support mechanisms for commercial agriculture are the direct government purchases (Aquisigdo do Gouemo Federal, AGF) and the provision financing of storage by the FEPM (Financiamento para Estocagem de Produtos Agropecuarios integrates da Politica de Garantia de Pregos Minimos) former Emprestimo do Gouemo Federal-EGF.
