ABSTRACT
The world population is expected to reach 9.3 billion in 2050 (UN, 2010). To feed this population, the Food and Agriculture Organization’s last global projection exercise forecasted that the world’s agricultural production will need to increase by approximately 70% by 2050, compared with the 2005 production levels (FAO, 2011). Approximately 80% of the increased agricultural production will need to come from yield increases, and higher cropping intensities such as increased multiple cropping and/or shortening of fallow periods.
