According to the pie chart, over-grazing contributes the largest share of land degradation, whereas both over-cultivation and deforestation are responsible for about one-third of total land degradation. The remaining 7% is accounted to a variety of other items.
Furthermore, Europe had the highest percentage of total land degradation with 23%, which all three factors including deforestation, over-cultivation, and over-grazing had a considerable contribution. (9. 8%, 7. 7%, and 5. 5% respectively). Oceania ranked second with 13% which the most proportion was accounted by over-grazing with 11. 3% and over-cultivation did not have any share in this area.
