According to Monbiot, who tackles worldwide prejudice against peasanthood:
[…] Though the rich world’s governments won’t hear it, the issue of whether or not the world will be fed is partly a function of ownership. This reflects an unexpected discovery. It was first made in 1962 by the Nobel economist Amartya Sen(2), and has since been confirmed by dozens of further studies. There is an inverse relationship between the size of farms and the amount of crops they produce per hectare. The smaller they are, the greater the yield.
In some cases, the difference is enormous. A recent study of farming in Turkey, for example, found that farms of less than one hectare are twenty times as productive as farms of over ten hectares(3). Sen’s observation has been tested in India, Pakistan, Nepal, Malaysia, Thailand, Java, the Phillippines, Brazil, Colombia and Paraguay. It appears to hold almost everywhere.
The finding would be surprising in any industry, as we have come to associate efficiency with scale. In farming, it seems particularly odd, because small producers are less likely to own machinery, less likely to have capital or access to credit, and less likely to know about the latest techniques.
There’s a good deal of controversy about why this relationship exists. […]
