It Just Doesn't Add Up

I challenge the math you quote from Ken Dunn of the Resource Center [City File, October 31]. The number 42,000 seems like a fairly large amount of jobs from 6,000 acres of land. One person can farm an average farm of 640 acres. It would take around 10 farmers to farm 6,000 acres. Let's say that there is one support person for every farmer. Thus it would take about 20 farmers if the 6,000 acres were contiguous. Given that the city acres are probably not contiguous, I guess it might reduce efficiency 95 percent, so I estimate it might employ 20 farmers and 380 people to move equipment from plot to plot. So maybe 400 people would be employed in farming 6,000 city acres. This is about 1 percent of the 42,000 that Dunn would employ.
