Fortunately, there is a nation with a highly successful family farming blueprint. That would be the United States, where more than 97 percent of all farms are of the family variety.
Of course, the U.S. model is highly diversified. There are small farms and really big farms. Some of them are incorporated for tax purposes or to ease transfer to the next generation.
Family farming is sometimes a subsistence practice. But to thrive, family farmers can look to America for things that work. Capitalism and free trade are good things to copy. Farmers must be profitable.
How about access to technology? Planting crops with natural pest resistance and drought tolerance would boost family farming everywhere. Some nations would need to clean up outdated and counterproductive rules.
If the UN wants to encourage global family farming, why not turn to a model that works.
