why agricultural land becomes less productive?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. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
The pie chart is provided for analysis of what impair the productive capacity of agricultural land. The table details these damages in three regions over the last decade of the 20th century. In this essay, I will distill key points to make informative comparisons.
Overall, on a global scale, deforestation, over-cultivation and over-grazing are the primary culprits, each accounting for approximately three tenth of land degradation. Among these regions listed, Europe was hit most severely during 1990s, with 23% of its land degraded. By contrast, the comparable proportions were 13% and just 5% for North America and Oceania respectively.
Globally, overgrazing-induced land degradation makes up 35% of the total. Deforestation and excessive cultivation take a close second and third place in harmfulness, leading to 30% and 28% of land degradation each. On the contrary, only 7% of land degradation is attributed to other reasons.
Regionally, over-grazing bore the most blame in Oceania, where it reduced 11.3% of soil to barren fields, compared with 5.5% in Europe and 1.5% in North America. With regard to deforestation, 9.8% of land in Europe became infertile for this reason, while the percentage was down to 0.2% in North America and 1.7% in Oceania. Likewise, though Europe saw 7.7% of its land damaged by excessive cultivation, only 3.3% of land in North America and o% in Oceania suffered the same problem.226 wordsThis time I practiced pie chart writing.
