The pie chart illustrates the
percentage of land degradaded by overgrazing, over-cultivation,
deforestation and other during the 1990s, and the table demonstrates data
regarding how much percentile of land was degraded in three different regions of
the world: North America, Europe and Oceania, during the same decade. Overall, during
the 1990s, over-grazing was the main cause for land degradation worldwide,
which affected Oceania the most.
Firstly, over-grazing accounted
to 35% of land degradation worldwide; this was 5 times more than the percentage
of land degraded by ‘other’ during the 1990s. Similarly, deforestation was the
second largest cause for land degradation worldwide (in the same decade), degrading
30 % land throughout the world. Over-cultivation,
on the other hand, degraded 28 % of land worldwide, which was four times more
compared to the percentage of land degraded by ‘other’.
Secondly, out of the total land
degraded worldwide (during the 1990s) 23 % was from Europe, 13% was from Oceania
and 5 % was from North America. Moreover, over-grazing degraded the highest
percentage of land in Oceania (11.3%), which was more than the percentage of
land degraded by overgrazing in North America and Europe combined (7%). Also,
deforestation caused 9.8 % land degradation in Europe, which was the chief
cause for land becoming less productive in Europe. Although over-cultivation
was the main reason for land degradation in North America, it did not affect
Oceania at all.
