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 chart and the table give information about why farmland was becoming degraded in the world and in 3 countries, namely - North America, Europe and Oceania during the 1990s. It is clear that the principal reason for global land degradation was due to overgrazing and deforestation. In the same year, we can also see that the European damaged agricultural land the most among three regions. Looking more closely at the pie chart, we can see that 35% of land destroyed in the world during the 1990s were for overgrazing. This figure followed by deforestation and over-cultivation, which accounted for 30% and 28% respectively. On the contrary, there was 7% of land that was degraded for other reasons. According to the table, in Oceania, overgrazing was the significant reason for destroying farmland with 11. 3%, which doubled the figure for Europe (5. 5%). Besides, 7. 7 % of land vitiated for over-cultivation purpose in Europe, making it the highest statistic in this discipline. Interestingly people in Oceania did not cut down farmland for this reason. The proportion of reducing agricultural land for deforestation was also highest in Europe, at 9. 8 %. Besides, the figure for North America ranges from 3. 3 % to 1. 5% in these 3 causes. Finally, in the 1990s, damaging farmland was most popular in Europe, which was 23% of agricultural land that was cutted down. This figure was twice and 4 times higher than the statistics in Oceania and North America.
