Farms in the developing world are mostly small and family-owned, and many of them have been cultivated for generations. These small farmers usually have only enough land to meet the needs of their families, or immediate community. Few small farmers have any control over the marketing and distribution of their produce, or even its price. For the small-scale farmer, selling produce is usually a secondary consideration, although the family may depend on this to buy household essentials. Some small-scale farmers have, however, begun to produce single crops for income.
