A new U of T study suggests that globally we’re growing more of the same kinds of crops, and this presents major challenges for agricultural sustainability on a global scale.
The study, done by an international team of researchers led by U of T assistant professor Adam Martin, used data from the U.N.’s Food and Agricultural Organization (FAO) to look at which crops were grown where on large-scale industrial farmlands from 1961 to 2014.
They found that within regions crop diversity has actually increased — in North America for example, 93 different crops are now grown compared to 80 back in the 1960s. The problem, Martin says, is that on a global scale we’re now seeing more of the same kinds of crops being grown on much larger scales.
