The pie chart illustrates the proportion of four factors that affect land degradation. Meanwhile, the table gives information about the effect of these four factors on North America, Europe, and Oceania in the 1990s.
From an overall perspective, it can be observed that the primary reason for decreasing the land's productivity is over-gazing. The table shows Europe has the highest percentage of degraded land, in contrast, North America has the smallest proportion.
The first graph displays the percentage of the four main reasons, including over-grazing, deforestation, over-cultivation, and others, which cause land degradation. As the pie chart depicts over-grazing with 35% ranks first. Deforestation with just 5% and 8% difference with over-grazing are the second and third factors.
The table presents that deforestation with 9. 8% and over-cultivation with 7. 7% has the highest percentage of land deforesting in Europe. Over-grazing accounts for 11. 3% of the land degrading in Oceania and is the major reason for this phenomenon. The table shows that North America with 5% and Europe with 23% has the lowest and largest total degraded land.
