Topic: 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.
The pie chart illustrates the main incentives why worldwide land was degraded around the world whereas the table depicts the impacts of these reasons on three different areas throughout the 1990s.
Overall, over-grazing was responsible for the majority of counterproductive agricultural land around the world. Likewise, the effects of three reasons varied considerably with Europe having the largest proportion of land degradation.
Over one third of global land were less productive owing over-grazing, 5% higher than the second major cause, deforestation. This was closely followed by over-cultivation that accounted for 28% while other factors constituted the remaining 7%.
Simultaneously, Europe suffered the largest loss of land productivity with around 23%, of which deforestation made up nearly one tenth. Over-cultivation and over-grazing took up relatively smaller percentages at 7.7% and 5.5% respectively. Meanwhile, the predominant cause of degradation of land in Oceania was over-grazing at approximately 11% out of a total of 13% while the other reasons had little impact. In North America, statistics for land degradation was lowest at 5%, mainly caused by over-cultivation with 3.3%.
