The pie chart shows different aspects which have the impact on the decrease of land productivity in the world.

The most significant factor is over-grazing (35 %); deforestation and over-cultivation have almost the same percentage of soil degradation, respectively 30% and 28 %.

There are other factors, but their negative influence on the land productivity is only 7 %.

Conversely, the table illustrates the degradation of land by regions in 1990.

Europe had almost a quarter of degraded lands caused by deforestation, over-cultivation and over-grazing with the rates at 9.8%, 7, 7 % and 5.5 % respectively.

13 % of Oceania lands and 5 % of North America soils were degraded by the same factors.

Overall, it can be seen that Europe over-used their land in different spheres, especially in wood production that caused more damage than the manufacturing in other regions from the table.

Oceania`s leading manufacturing sphere was cattle raising and this sphere played the most ruinous role in the land degradation.

However, the rates of factors of land degradation in North America were rather low; it means that this region caused the least damage to the world nature.
