The pie chart below show the main reasons why agricultural land becomes less productive. The table shows how these causes affected three regions of the world during the 1990.Causes of land degradation by region

The data sources highlighted four main causes of land degradation globally and the proportion pattern in three different regions. Overall, deforestation, overgrazing and overcultivation accounts for the major reasons of less productive land and this displays unevenly in North America, Europe and Oceania.

Worldwide land degradation was attributed to the three causes mentioned above approximately at one third each, other reasons constituting a minimal 7% collectively.

However, regional land degradation reveals significant differences in causes. In Oceania, 13% land was degraded, 11% of which was caused by overgrazing. In contrast, shrinking forests resulted in 1.7% and there was no over farming problems in this region in 1990s. Severe land degradation happened in Europe, an alarming 23% land becoming less productive with all three causes contributing their share: deforestation the highest 9.8%, overcultivation 7.7% and overgrazing 5.5%.

Compared to Europe and Oceania, North America saw a much lower ration, 5% in total, over farming and over grazing made up over 95% causes, deforestation being a negligible 0.2%.
