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.

The given pie chart illustrates four significant causes of farmland’s decrease in productivity and, additionally, the tabular chart provides information about the percentages of how north America, Europe and Oceania’s are influenced by these crucial causes. Overall, globally, 65% of land degradation consists of deforestation and overgrazing, respectively, at 30% and 35%. While, over-cultivation accounted for 28% pf the total pie chart. Moreover, analysing the table, it is absolutely clear that the European region is the most over-used region. With regards to Europe, the total percentage of land which are less productive is almost a quarter, 23%. It is also worth pointing out that this region had the highest rate in two categories; deforestation at 9. 8%, almost five times Oceania’s rate which is at 1. 7%, and over-cultivating at 7. 7%. Another noticeable result is North America’s trend which is revealed to have the lowest rate of total land degraded, only 5%, compared to 13% of Oceania. However, the lowest percentage between the three regions is reported by over-cultivating in Oceania with a extraordinary 0%.
