In Japan it would be beyond most farmer's dreams. When he told them that farmers with a quarter section of land would starve in most areas of Manitoba they were sure he was spouting Commie propaganda. THis was when Hungary was communist. It would be nice to have some statististics. I expect the trend is that larger farms are increeasingly responsible for a larger proportion of total production but that smaller farms may not be decreasing all that quickly in number.
Many smaller farms survive by family members having off-farm jobs.
I expect that the number of hobby farms may be increasing as well.
