Carbon footprint of homegrown food six times greater than those grown conventionally
A new University of Michigan-led international study finds that fruits and vegetables grown in urban farms and gardens have a carbon footprint that is, on average, six times greater than conventionally grown produce.
"Most of the climate impacts at urban farms are driven by the materials used to construct them -- the infrastructure," Goldstein said. "These farms typically only operate for a few years or a decade, so the greenhouse gases used to produce those materials are not used effectively. Conventional agriculture, on the other hand, is very efficient and hard to compete with."
For example, conventional farms often grow a single crop with the help of pesticides and fertilizers, resulting in larger harvests and a reduced carbon footprint when compared to urban farms, he said.
