| Land Degradation |
The given pie chart illustrates
major causes of worldwide land quality deterioration during 1990s, whereas the table
highlights reasons of land degradation in three regions.
Over-grazing (35%) was the primary reason of worldwide land quality deterioration followed by shrinking forest cover, over cultivation and other causes with corresponding figures of 35 %, 30% and 28% respectively.
The table compares causes of land
degradation in North America, Europe and Oceania. Europe lost major parcel of land, i.e. 23%,
while percentage of land deteriorated in North America is merely 5%. The primary
cause of land degradation in Europe is reducing forest cover (9.8%) whereas, North
America lost most of its land due to agriculture (3.3%) and in case of Oceania use of land as pastures
accounted for maximum loss of land (11.3%).
In addition, deforestation in
Europe was much higher than North America and Oceania. Over use of land for
agriculture was quite expansive in North America and Europe, except Oceania.
In conclusion, over-grazing was main reason of worldwide degradation in 1990s.
