Changes in agricultural land (pasture and cropland)

Year: 2007 Author: Philippe Rekacewicz, Emmanuelle Bournay, UNEP/GRID-Arendal
Description:
For all developing countries over the period 1961–99, expansion of harvested land contributed only 29% to growth in crop production versus the contribution of increases in yields, which amounted to 71%; in sub-Saharan Africa, however, yield increases accounted for only 34% of growth in production.
