The pie chart gives data on the major causes why agricultural soil grows less fertile. The table depicts how three territories of the world are influenced by these reasons during the 1990s. Measurement is in percentage.
Overall, over-grazing accounted for the great amount, while other factors reached the lowest peak. Moreover, the maximum percentage of land was degraded by deforestation in Europe, whereas minimum quantity was observed by deforestation in North America during the 1990s.
In detail, over-grazing was equal to 35%, while the total ratio for deforestation decreased to 30 %. This indicator for over-cultivation made up 28%, however the minumum amount of other causes became 7%.
Furthermore, in Europe total land degradation accounted for 23%. Deforestation and over-cultivation stood at 9, 8 and 7, 7 % respectively, whereas over-grazing reduced to 5, 5%. In Oceania over-gazing rose to 11, 3 %, however, over-cultivation levelled off and the amount of deforestation made up 1, 7%. In North America there was a significant decrease in amount of total land degredation, reaching to 5%. These figures for over-grazing and deforestation stood at 1, 5 and 0, 2 % accordingly, while over-cultivation went up to 3, 3%.
