The pie chart gives information about main factors in worldwide land degradation, while the table gives information about the proportion of these effects in three particular regions.
Overall, over-grazing, forest clearance and over-cultivation were major causes of soil deterioration in the world. It is also clear that, the proportion of degraded land in Europe was higher compared to the other two areas.
Over-grazing was responsible for a high of 35% of degradation of soil globally, while the index for deforestation and over cultivation was almost proportional(30%and 28%)
The total of poor quality land in Europe was equal to 23% with North America having the least proportion, 5%.
In terms of deforestation and over cultivation, their percentage in Europe was the highest among other regions accounting for 9. 8 and 7. 7 accordingly.
However, in Oceania 11. 3 of land was made infertile due to livestock. It also noticeable that no soil in this region was degraded by overusing.
