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.

This

pie chart illustrates that agricultural land has produced few amounts of produce for several main reasons. The table graph depicts different processes that affect three continents (North America, Europe and

Oceania

). It is clear from the data that over-grazing has the highest proportion among other causes.

In addition

, over-grazing in

Oceania

has been calculated to be the hugest which is 11.3 per cent.

According to

what is shown, there is a slight difference between deforestation, over-grazing and over-cultivation, but (other) has the lowest data and measured with 7 proportion.

However

, over-grazing takes up the biggest space when it comes to the reasons for worldwide land degradation.

On the other hand

, over-cultivation especially in

Oceania

has not shown any violence to lands, which is considered a friendly process to that region.

Furthermore

, over-grazing has been affecting the

Oceania

region so dramatically.

Moreover

, deforestation in North America has an almost similar output of over-cultivation in

Oceania

which has a slight increase, around a percentage of 0.2.

To sum up

, over-grazing has been selected to be the largest cause that affects the earth's surface more than other methods.

Also

, in terms of the reasons in a specific region, over-grazing in

Oceania

has the lion share’s and ultimately it presents the most effective causes of land degradation.
