The pie chart below shows the main reason why agricultural land becomes less productive. The table shows how these causes affected three regions of the world during 1990s. Summarize the information by selecting and reporting the main features, and make comparisions where relevant.

The first pie chart illustrates major factors that lead to the deterioration of agricultural land. The table shows the situation in three world areas where these factors were influenced throughout the 1990s. The chart includes 3 main factors causing soil downturn worldwide, namely deforestation,

over-cultivation

and over-grazing. The biggest proportion was over-grazing with 35 per cent. Less than

this

5 per cent was deforestation and the third rank belonged to

over-cultivation

with a percentage of 28%.

Lastly

, there is 7% of other reasons. The table contains 3 regions in the world that were mostly affected by these causes. In North America, the soil endured the least devastation (about 5%

overall

) with the main factor being

over-cultivation

(3.3%). In Europe, all 3 causes were all at a high level that contributed greatly to the total of 23%.

Moreover

, Oceania ranked second place,

however

, the causes were largely different from each other in their damage rate.

In particular

, the over-grazing contribution was 11.3% but there is no damage from

over-cultivation

.
