The pie chart shows why agricultural land in America has become less productive. The table shows how these causes affected the three regions in the Americas.
Summarise the information reporting the important features and make comparisons where relevant.

Answer

The pie chart shows the causes of land degradation (deforestation, over-cultivation, over-grazing and other causes) in North, Central and South America, while the bar chart shows the percentage of land degraded in America by cause and region and the total percentage of land degraded.

The pie chart shows that over-grazing makes up 35% of land degradation while deforestation and overgrazing are responsible for 32% and 27% of land degradation, respectively. Other causes of land degradation make up 8% of the total degradation.

Central America has by far the highest level of land degradation at 13.8%,which is caused by deforestation (6.2%), over-cultivation (4.9%) and over grazing (2.3%). Approximately 13% of land in South America is degraded and is caused by deforestation (6.3%) with smaller contributions from over-grazing (4.4%) and over-cultivation (2.3%). North America has by far the lowest level of
land degradation at 5.8%, which is mainly due to over-cultivation (3.7%) and overgrazing (1.8%). Deforestation made up only 0.3% of land degradation in North America.
