The given pie chart vividly portrays the main reasons behind land degradation , making it less productive. Similarly, the table provides a comprehensive overview of how the three regions of the world are adversely affected by these causes during the 1990s.
As can be seen from the graph, overgrazing the main cause behind worldwide land degradation, over 35% of the land is degraded by overgrazing, including countries like Oceania, in which 11.3% is degraded by herbivores, and similarly its contribution in Europe is 5.5% of the total land degraded.
Deforestation is the second major issue, contributing to soil erosion. 30% of the total land is degraded by cutting away of trees. It has adversely affected Europe by degrading 9.8% of the 23% spoilt land, while it has less effect on the North-America, and Oceania. In the same manner, over grazing has affected 25% of the total agricultural land, and it is evident from the graph that it has affected 11.3% of the land out of 13% eroded land in Oceania.
To conclude, the presented table summaries that North America has the least percentage of degraded land while Europe has the most degraded land for agriculture. Specifically, over-grazing and deforestation are the major contributors in soil erosion, making the land available less productive.
