The table illustrates reasons why fertile land became less productive in three vary regions during 1990s based on the main causes of degradation in all over the world. It can be seen from the pie chart that the major factors which affect productive land is; over-grazing, deforestation and over-cultivation, 35, 30 and 28 percent respectively.

In Europe total land degradation was higher than other two regions, 23 percent. Deforestation was essential reason which declined productivity in Europe during 1990s, about 10 percent. Europe also exceeds North America and Oceania for over-cultivated land, 7.7 percent. The second region due to causes of total land degradation was Oceania, 13 percent. Over-grazing took the first place which made agricultural land less fertile, about 11 percent. It seems that land in Oceania have not been over cultivated at all.

In contrast to Europe and Oceania, land degradation was less in North America, five percent. Over-cultivation was core reason which caused to land degradation in North America in 1990s, 3.3 percent.
