Band 8+: The pie chart below shows the main reasons why agricultural land becomes less productive. The table shows how these causes affected three regions of the world during the 1990s. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The pie graph displays the primary reasons why rural lands turned out less fertile, while the accompanying table illustrates how three continents, which are North America, Europe, and Oceania, were affected by the degradation during the 1990s.

Overall, it can be seen that over-grazing and deforestation were the main factors for land degradation in the world. In addition, Europe was the most severely affected by these disasters, while North America was the least impacted.

Over-grazing accounted for over a third of all worldwide land degradation, compared to deforestation, which made up 30%. Over-cultivation, on the other hand, was another crucial factor that resulted in land degradation, with over a quarter, while others have an insignificant proportion of contribution, with 7%.

In terms of specific regions, Europe was mostly affected by deforestation, at almost a tenth, in comparison to Oceania, where over-grazing was the most serious catastrophe. Over-cultivation, however, was the most threatening factor for North America, although it was totally affected only by 5%, while Europe and Oceania were 23%, and 5%, respectively.
