The pie chart displays the major causes of global land degradation, while the table illustrates how three regions of the world were affected by these causes during the 1990s.

Overall, over-grazing, deforestation, and over-cultivation are the main reasons why agricultural land worldwide is degraded. Europe had a much higher percentage of degraded land than Oceania and North America.

Over-grazing, which accounts for 35% of the world’s degraded land, is the single biggest reason for global land degradation. Deforestation and over-cultivation constitute another 30% and 28% respectively.

Of the three regions, Europe had the greatest proportion of degraded land during the 1990s, at 23%. However, there, the biggest factor was not over-grazing but deforestation, which caused 9.8% of the land to become less productive. Oceania was the second most affected region, with a total of 13% of its land degraded, and this was mostly caused by over-grazing, at 11.3%. It is also noteworthy that Oceania didn’t over-cultivate its land. In comparison, only a total of 5% of the land in North America was degraded and over-cultivation, responsible for 3.3%, was the biggest cause. (185 Words)

How to Understand the Pie Chart

A certain percentage of the world’s land is degraded, but we are not told what this percentage is. As you can see, the percentages in the pie add up to 100 (35+30+28+7). This doesn’t mean that 100% of the world’s land is degraded. The pie chart only tells us that over-grazing, for example, accounts for 35% of the world’s degraded land, not 35% of all the world’s land. So don’t say something like “35% of land worldwide is degraded by over-grazing”.

  1. The pie chart illustrates the major causes of agricultural land degradation worldwide whereas the table shows the statistical information about the effects of these reasons in three regions of world.

    We come to know from the pie chart that there are three main reasons behind the degradation of farmland and these are over-grazing, deforestation and over-cultivation. Over-grazing is the most dominating reason, decreasing about 35% of farmland productivity. Deforestation and over-cultivation are the other two factors that diminish about 30% and 28% farmland land productivity respectively. There is another portion in the pie chart which is denoted by others and causes just 7% of degradation.

    Europe is the most agricultural land degraded region which is about 23% and main factor behind this is deforestation. About 11.3% land degradation is served by over-grazing among 13% in Oceania. North America is the least affected area whose quantity of land degradation is only about 5%.

  2. I want to know how much will i get from this answer.

    The pie chart reflects the reasons of worldwide land degradation. It shows us that 35% of the land degradation is caused by over-grazing, 30% is because of deforestation, 28% is lead by over-cultivation and the rest 7% is caused by other minor problems. So, in other words, the main reason of land degradation is over-grazing and the minor reason is the other short problems which are not mentioned specifically.

    In the table it shows us the similar things but it also contains the percentage of land degradation by regions. It shows us that North America’s total land degradation is 5% which includes 0.2% of deforestaion, 3.3% of over cultivation, 1.5% of over-grazing. In Europe, the total land degraded by 23% and for Oceania, it is 13%.

    Overall, Europe is the highly damaged by the land degradation and we can see that the main reason is deforestation and over-cultivation, which contains 9.8% and 7.7% out of 23%.

  3. The chart provides data about how the degradation of land has occurred over the whole world, and the table shows the percentage of land degradation in several regions between the year 1990 to 1999.

    Firstly, it can be noted that overgrazing due to high demand of beef and milk has caused most of the damage to agricultural land which is 35%. Similarly, deforestation and over-cultivation has severe impact contributing 30% and 28% along with 5% of other factors.

    To be specific, Europe has lost the most quantity of cultivating land between the year 1990 to 1999 which is 23%. Oceania and North America are in very good condition as compared to Europe in the above mentioned years with 13% in Oceania and only 5% in North America.

    It must be mentioned that deforestation in Europe is the most contributing factor for land degradation, followed by over-cultivation and over-grazing. Oceania exceeds all other regions in over-grazing and there is very slight effects of deforestation but cultivation was done within harmless limits. So far, North America has been in the safest side with very little deforestation and over-grazing and slight over cultivation that caused land degradation.

  4. Hi, thank you for your sample answer and explanation. I left my essay below, how would you assess it? Thank you again in advance

  5. The pie chart illustrates the main causes of the low productivity of agriculture, while the table gives information about three regions of the world affected by them during the 1990s.

    Overall, over-grazing, deforestation, and over-cultivation are the main culprits of land degradation. Europe was affected the most, as opposed to North America, which suffered the least from this problem.

    In terms of over-grazing, it comprises 35% of land deterioration, remaining the main issue. With regard to over-cultivation and deforestation, they account for another 28% and 30% respectively, leaving a tiny 7% for other reasons.

    Although globally over-grazing made up the largest part of the pie chart, Europe was impacted mainly by deforestation, which accounted for just under one-fifth of the total 23% of degraded land. The second region most affected by this issue was Oceania, with the total 13%, where over-grazing was the main concern and constituted 11.3%. Interestingly, in Oceania over-cultivation didn’t have any influence on the land condition; however, in North America it accounted for 3.3% of the total 5% and was the biggest challenge.

  6. “Over-cultivation, responsible for 3.3%, was *again* the biggest cause.”

    Where was it the biggest cause the first time ?

  7. Hi Ms. Lilie, I saw that you used different tenses when describing the chart and table. Could I use past tense for both? Thank you.

    1. Hi, thanks for your question. No, you can’t. Please read the question carefully. For the pie chart, it uses the simple present tense “becomes”. But for the table, it uses the simple past “affected”.

      1. I’m very sorry that I don’t do essay corrections now. But if you have any specific questions about writing, please ask. I’ll try my best to answer.
