Résumé
The predominance of family farms in agrarian structures in various regions of the world (Chap. 3) and the size of their territorial extent (Chap. 7) ensures that their share in the production of food and agricultural commodities is substantial. Their dominance is also reflected in their contributions to international markets, which are largely supplied by family farms. However, there exist significant differences depending on food and non-food types of products: staples (cereals, tubers and plantains, legumes, oilseeds, sugar plants), animal products, fruits and vegetables, stimulants (coffee, cocoa, tea), textile fibers and rubber.
