This chart is from the recent Iowa State AGMRC publication, “Can We Meet the World’s Growing Demand for Food?” by Don Hofstrand. The writing includes many issues related to global food security. Note that South America’s arable land per person value is equal to Sub-Saharan Africa’s. (Also note correction: Middle East and North America should read Middle East and North Africa)
I look forward to Hofstrand’s future writing about how biofuels will and do affect global food security, which he says is coming soon.
