What to know about Global access to food crops is affected by transport costs and economic inequality

A study led by the University of Oulu examines how transport networks and economic inequality impact the global accessibility of food crops. The research indicates that while food production is necessary, transport costs and income disparities often prevent supplies from reaching regions with high demand, particularly in Asia and Africa.
