As observed in other baseline scenarios, in the [[Roads from Rio+20 (2012) project|Rio+20]] baseline the expansion of agricultural production in tropical regions leads to a loss of natural ecosystems, and an associated loss of biodiversity. In fact, most of the expansion is projected to occur in highly productive ecosystems near existing agricultural areas, thus including tropical forests and woodland, other high nature value savanna and grassland area. At the same time, in the temperate zones there is actually a contraction of the agricultural area. Here, the grid cells least suitable for production potential are abandoned. The resulting changes in agricultural area are depicted in the figure on the left. | As observed in other baseline scenarios, in the [[Roads from Rio+20 (2012) project|Rio+20]] baseline the expansion of agricultural production in tropical regions leads to a loss of natural ecosystems, and an associated loss of biodiversity.
