Abstract
Many factors will shape global food security over the
next few decades, including changes in rates of human
population growth, income growth and distribution,
dietary preferences, disease incidence, increased demand
for land and water resources for other uses (i.e. bioenergy
production, carbon sequestration and urban development)
and rates of improvement in agricultural productivity.
This latter factor, which we define here simply as crop
yield (i.e. metric tons of grain production per hectare of
land), is a particular emphasis of the plant science com-
munity, as researchers and farmers seek to sustain the
impressive historical gains associated with improved
