Small Is Bountiful

Peasant farmers offer the best chance of feeding the world. So why do we treat them with contempt?

I suggest you sit down before you read this. Robert Mugabe is right. At last week’s global food summit he was the only leader to speak of “the importance … of land in agricultural production and food security”.(1) Countries should follow Zimbabwe’s lead, he said, in democratising ownership.

Of course the old bastard has done just the opposite. He has evicted his opponents and given land to his supporters. He has failed to support the new settlements with credit or expertise, with the result that farming in Zimbabwe has collapsed. The country was in desperate need of land reform when Mugabe became president. It remains in desperate need of land reform today.

But he is right in theory. 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 most plausible explanation is that small farmers use more labour per hectare than big farmers(5). Their workforce largely consists of members of their own families, which means that labour costs are lower than on large farms (they don’t have to spend money recruiting or supervising workers), while the quality of the work is higher. With more labour, farmers can cultivate their land more intensively: they spend more time terracing and building irrigation systems; they sow again immediately after the harvest; they might grow several different crops in the same field.

In the early days of the Green Revolution, this relationship seemed to go into reverse: the bigger farms, with access to credit, were able to invest in new varieties and boost their yields. But as the new varieties have spread to smaller farmers, the inverse relationship has reasserted itself(6). If governments are serious about feeding the world, they should be breaking up large landholdings, redistributing them to the poor and concentrating their research and their funding on supporting small farms.
