The pie chart introduces the main cause of worldwide land degradation during the 1990s in the percentage scale, whereas the table shows reasons of land degradation by three regions: North America, Europe and Oceania.

Over-grazing was the main reason of worldwide degradation and it reached 35 %. 30% and 28% of degradation was due to deforestation and over-cultivation respectively, leaving 7% for other reasons. It can be seen from the table, that Europe had the largest percentage of land degradation, which was 23%. The lowest percentage of land degradation was in North America and it reached only 5%. In Europe deforestation was the main cause of land degradation (9.8%), while in North America and Oceania – over-cultivation (3.3%) and over-grazing (11.3%) respectively. In addition, deforestation percentage in Europe was higher than North America’s and Oceania’s combined. In North America and Europe over-cultivation numbers were quite large, while in Oceania there was no land degraded by over-cultivation.

In conclusion, over-grazing was the main cause of worldwide degradation in 1990s. Europe percentage of degradation was largest of all three regions and all three regions had different predominant causes.
