The housing-price boom of the 2000’s was little more than a construction-supply bottleneck, an inability to satisfy investment demand fast enough, and was (or in some places will be) eliminated with massive increases in supply. By contrast, there has been no increase in the supply of farmland, and the stories that would support a contagion of enthusiasm for it are in place, just as they were in the 1970’s in the US, when a similar food-price scare generated the century’s only farmland bubble.
