Question – 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. Write at least 150 words.
A table that compares the degradation of agricultural land by region in the 1990s—including North America, Europe, and Oceania—and a pie chart that is divided into four sections show the main causes of agricultural land degradation worldwide.
Overgrazing accounted for 35 percent of the total causes of land degradation, with deforestation coming in second with only five percent. The third main factor contributing to agricultural land degradation is overcultivation. The remaining factors only account for 7% of the chart, with each of the three reasons occupying approximately the same equation.
With most of the land degraded due to deforestation, Europe has the worst degradation when compared to the other two regions. The two primary causes of the less productive agricultural land in Oceania, which has a total degradation rate of 13 percent, are overgrazing and deforestation. The table indicates that overcultivation, however, has no effect on the land in Oceania.
According to the table below, North America has the least degraded land. According to this, over-cultivation accounted for 3.3 percent of the total land degradation in the 1990s, or only 5% of the land degradation.
