The pie chart illustrates the causes of farmland degradation, whereas the table depicts the three affected regions' cause of land degradation in 1990.
Overall, for the pie chart, most of the agricultural lands were degraded by animal grazing, while the table shows that the percentage of soil degradation was high in Europe compare to the other regions.
As can be seen in the pie chart, amongst the four reasons provided, 35% of soil were degraded by animal-grazing, while deforestation took second place about 30%. Moreover, 28% of global degradation was due to over-cultivation of crops. The remain other 7% farmland degradation caused for unkown reasons.
As far as the reason for total land degradation was 23% in Europe while other two region had less percentage about 13% and 5%. Futhermore, 9. 8% of land degraded by deforestation in Europe whereas North America and Oceania were less affected by deforestation. Europe, with the highest percentage land degraded by more cultivation of yield about 7. 7%, while North America and Oceania were less affected by it. In Oceania, the main cause of soil degradation for animal-grazing with 11. 3% whereas 5. 5 in Europe and only 1. 5% in North America.
