Pie chart - Causes of worldwide land degradation

Causes of land degradation by regions, 1990s

Sample Answer 1:
The pie chart indicates the factors that negatively affect the productivity of agricultural lands worldwide while the table data illustrates the percentage of land degradation in three main regions due to those factors mentioned.

From the pie chart, it can be seen that the major factor that causes the worldwide land degradation is over-grazing. 35% of agricultural lands worldwide become less productive due to a single factor – over-grazing. Deforestation is accounted for 30% degradation of cultivable land while over-cultivation results 28% land degradation. All other minor reasons are categorised as ‘other’ and constituted 7% loss of land fertility.

The given table data shows the percentages of agricultural land degradation in three regions during the 1990s, namely – North America, Europe, and Oceania. Oceania comprised many islands in the South Pacific area including New Zealand and Australia. The analysis shows that highest percentage of land degradation, 23%, occurred in Europe in the 1990s. This is followed by Oceania and North America where these percentages were 13% and 5% respectively. The most striking feature was that over-cultivation had zero impact in Oceania as it was mostly affected by over-grazing.

Sample Answer 2:
The given picture contains two charts, one pie chart and another table chart. As is observed from the pie chart, the main reason for less productivity is overgrazing of animals which constitutes 35%. Another big reason of land degradation is deforestation which holds 30% of the total. Over cultivation also affects the production of land which constitutes 28% while other reasons of land degradation are remaining 7%. As a result, the biggest reason of land degradation is overgrazing of animals in agricultural land.

According to the given table, we will analyse what are main causes of less production of land in different regions and how they affect the lands’ production. As it can be seen clearly, that Europe is badly degraded by 23%. Europe is degraded by deforestation by 9.8% while 7.7% is affected due to over cultivation and finally, 5.5% degraded by overgrazing. Europe is affected badly by 23% while North America holds 5% and Oceania by 13%.

In conclusion, Europe is badly affected by these factors in all of the regions.

Sample Answer 3:
The given pie chart and table depict the significant causes of less productivity of agricultural land in three parts of the world in the 1990s. As is observed from the pie chart, the main reason for land degradation around the globe is due to over-grazing. It can be clearly seen from the table that Europe had the highest percentage of total land degraded than the other two regions.

Over-grazing is the main cause of worldwide land degradation which accounted for 35%. It is followed closely by deforestation which is 5% less than overgrazing by herbivores. The third reason why agricultural land degraded is caused by over-cultivation, accounted for 28%. The non-specific reason which is categorised as ‘other’ stood at 7%.

Europe has the highest percentage of land degraded which is 23% in comparison with Oceania which consists of the huge group of islands in the South Pacific including Australia and New Zealand (13%) and North America (5%). In Europe, the most detrimental cause of land degradation is deforestation by human beings which stood at 9.8%, whereas in Oceania, it is caused mainly by over-grazing which accounted for 11.3% than deforestation (1.7%). Over-cultivation did not contribute to the cause of land degradation in Oceania but it was the main reason that led North America to face the land degradation problem, which accounted for 3.3%.

Sample Answer 4:
The pie chart below is divided into four different sections, illustrates the main reasons why agricultural land degrades around the world, while the table compares the degradation by regions, including North America, Europe and the Oceania, during the 1990s.

The predominant reason for land degradation would be over-grazing, taking up a percentage of 35 while deforestation fell into the second main reason with only five percent behind. Over-cultivation is the third major cause of the agricultural land to degrade. Each of the three reasons takes up roughly the similar equation while the other factors only cover 7 percent in the chart.

In Europe, the degradation is the worst in comparison to the other two regions, having the majority of the land degraded from the result of deforestation. Oceania has the total degradation of 13 percent with two main reasons that are responsible for the less productive agricultural land, including over-grazing and deforestation. Over-cultivation, however, has none effect toward the land in Oceania according to the table.

North America has the least degradation in the lands in the table below. It indicates that the land degraded in only five percent in the 1990s with the main cause of over-cultivation, taking up the percentage of 3.3 of the total degradation of 5 percent.
