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 provided pie chart and accompanying table detail the primary causes of agricultural land degradation and their respective impacts on three distinct regions during the 1990s.

In summary, overgrazing emerged as the predominant cause of global land degradation, with Europe experiencing the highest levels of degradation, while North America recorded the lowest.

The pie chart illustrates that overgrazing is responsible for 35% of land degradation worldwide, followed closely by deforestation at 30% and agricultural activities, which account for 28%. It is noteworthy that other factors contribute a mere 7% to this global issue.

The table provides a regional breakdown of land degradation consequences. In North America, the combined degradation figures stand at 7.1%, with deforestation providing 3.3% and agricultural activities 2.1%, while overgrazing and other causes account for minimal percentages. Conversely, Europe experiences a total degradation of 4.5%, predominantly attributed to overcultivation, which peaks at 77%. Interestingly, Oceania, with an overall degradation of 7.5%, identifies overgrazing as the principal factor at 5.7%, highlighting a regional disparity in the impact of agricultural practices.
