Family farms are the predominant form of agriculture worldwide. They account for over 500 million of the 570 million total farms globally. While most farms are small in size, large farms control most of the world's agricultural land. Family farms are important for food security as they produce much of the world's food, especially for certain commodities. However, they need support through innovation and investment in research to increase yields sustainably and raise incomes. The document discusses policies and initiatives to strengthen family farms, including through defining them, improving access to resources and markets, and including family farms in the post-2015 development agenda.
