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.
You should write at least 150 words.
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.
