Over-grazing of agricultural land was the main cause of its degradation in the nineteen nineties.

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 pie chart presents the major causes of agricultural degradation; moreover the table informs how these issues affected three nations of the world over the 1990s. As an overall trend, it can be clearly seen that over-grazing is the major issue of land degradation, particularly in Oceania which is the large group of islands in the south pacific.

In the 1990s, the degradation of agricultural land was mainly caused by over-grazing, representing 35%. Mostly, it occurred in Oceania, 11.3% and interestingly, over-cultivation in the region was zero percent. In addition, less than a third, deforestation was second cause of land degradation, that European countries were the highest contributor, amounting 9.8%. The other causes were over-cultivation as well as other, which had 28% and 7% respectively. And again, it was commonly degraded by European countries, 7.7%.

To sum up, 23% of agriculture land in European countries was degraded, which was the greatest rate of all regions. What is more, North America which had the lowest number of land degraded and Oceania had amount 5% and 13% respectively.

What you have written about is the actual pie graph shown. The pie graph gives us all of the information that we need, so we do not necessarily need three paragraphs about the pie chart.The paragraphs need to be about what is over-cultivation, over-grazing, and deforestation. You will need to write what these acts are and then what areas are affected by them. Have one paragraph for each item that includes a definition and an example of it, and then talk about which country is affected the most by the act.
