Of the 13.2 billion hectare global land use, 12 percent (1.6 billion ha) is currently in use for cultivation of agricultural crops, 28 percent (3.7 billion ha) is under forest,and 35 percent (4.6 billion ha) comprises grasslands.
Livestock farming comprises almost 30% of the earth’s land. About 20 percent of the world’s pastures and rangelands, with 73 percent of rangelands in dry areas, have been degraded to some extent, mostly through overgrazing, compaction and erosion created by livestock action.
Only 20% of land is used for the direct production of the crops used for human consumption.
More and more land use is used for conversion of farmlands due to reduction in productivity of lands.
