That's true, but we do have populations that are closer to control. There's still quite a few people who engage in subsistence farming in less industrialized nations.

For example, the rice farmers in the northern Philippines (excluding Banaue which is heavily touristed). They've certainly benefited in the last century from medicine, a stable government that prevents their historical tribal warfare, and cheaper manufactured goods, but their actual farming hasn't changed a whole lot.
