Steve Wiggins, a rural development expert at the Overseas Development Institute, said: "There are very few economies of scale in most agriculture above the level of family farm because managing [the] labour is extremely difficult."
Stevie laddie, I\’m sorry but you are severely deluded here. The "family farms" that we\’re talking about are peasants scratching away at an acre or two of soil. There are massive economies of scale from this up to the size of the American or British farm.
Try reading some Paul Collier: what Africa needs is a great deal more industrial and commercial agriculture, not less.
