The table provides information about the rate of land degradation by three main causes namely ; deforestation ,

over-cultivation

and overgrazing in three different regions (North America , Europe and Oceania). In general, the data in the table indicate that the highest rate of degraded land was in Europe ,

while

, North America had the smallest area of degradation. To start with , it is clear from the data that Europe had the largest area of degraded lands with a total of 23% , and the main reasons for

this

trend were erosion ,

over-cultivation

and overgrazing by rates of effect 9.8% , 7.7% and 5.5% respectively.

However

, Oceania recorded 13% of degraded lands , and the major reason was over-grazing at 11.3% followed by deforestation at 1.7% , and without presenting any effect of the

over-cultivation

factor at 0%.

Nevertheless

, North America recorded the lowest rate of degradation at 5% in total ,

nonetheless

,

over-cultivation

was the main cause at 3.3% ,

also

over-grazing at 1.5% was the second cause , and erosion

at the end

at 0.2% .
