31. Globally, most people are (and will be) in mixed crop – livestock systems Mixed systems produce 65% beef, 75% milk and 55% of lamb in the developing World Mixed systems produce almost 50% of the cereals of the World and the share will increase to over 60% by 2030

The way animal protein will be produced will change profoundly. Industrial type of production will grow much faster than land-based production. Grazing systems face important resource constraints. Mixed farming, too, cannot expand at the pace of demand for animal products. This trend is uniform throughout the major regions of the developing world, but particularly pronounced where the demand for animal products is growing fastest.
