Increase in harvested land: The area of existing croplands harvested grew by 7 percent between 1985 and 2005. In this feature, we consider how increasing crop production can be part of the solution by examining its potential and limitations.

With the world population rising, demographers are grappling with one of the most pressing issues of the century - will there be enough food for an extra two to four billion people? Studies of major crop groups (including cereals, oilseeds, fruits, and vegetables) indicate that production increased by roughly 47 percent between 1985 and 2005. Altogether, these trends mean we won’t be able to double crop production by 2050 through business-as-usual yield growth alone. If the population continues to increase there will come a point in the future when the earth will not be able to produce enough food to support the human race. More than 9 billion people in less than 40 years. Just four crops—maize, rice, wheat, and soybeans—provide two-thirds of the calories we harvest from fields.
