The pie chart represents the main four causes of worldwide land degradation which are deforestation, over-cultivation, over-grazing and other. On the other hand, the table describes the effects of these causes to three regions of the world during the 1990s.
Overall, as is observed from the given data from the pie chart, it is obvious that the majority of the worldwide land degradation is caused by deforestation and overgrazing. However, as shown in the table, it was deforestation and over-cultivation which caused the degradation in Europe by both of them accounting for 17.5% out of 23%.
Looking specifically at the pie chart, over-grazing was the primary contributor of global degradation, comprising a just over a third of the total degradation. Following up, three tenths of global degradation were affected by deforestation. Lastly, over-cultivation and other factors were the causes of farmland becoming degraded making up 28% and 7% respectively.
Unlike the pie chart, Oceania was the only region which got the largest effects in farmland caused by over-grazing among the three regions, (North America, Europe, and Oceania). Additionally, in North America and Europe, over-cultivation and deforestation took a lead respectively. Europe specifically showed a significant impact by deforestation and over-cultivation, with these two factors jointly contributing the majority of the farmland degradation.
