The pie chart below shows the main reasons why agricultural land becomes less productive. The table shows how these causes affected the three regions of the world during 1990s.

The

pie

chart

illustrates the primary

factors

contributing to global

land

degradation

,

while

the

table

demonstrates the impact of these

factors

on three specific regions of the world in 1990; North America, Europe, and Oceania. When considered together, the information indicates no correlation between the percentage of each factor represented in the

pie

chart

and the corresponding consequences attributed to those same

factors

as depicted in the

table

. In the

pie

chart

, it is evident that the major cause of

land

degradation

is over-grazing.

However

, the

table

presents varying results for each region. Key contributors to

land

degradation

in these regions include 3.3% of

land

in North America affected by over-cultivation, 9.8% in Europe degraded by deforestation, and 11.3% in Oceania impacted by over-grazing.

Additionally

, the

table

outlines deforestation as a minor cause of

land

degradation

, which is corroborated by North America's figure of only 0.2%.

Nevertheless

,

this

is not the case for Europe, where over-grazing accounts for 5.5%, and Oceania, which shows 0% for over-cultivation.

Overall

, the figures suggest no apparent association between the two mediums used to gather data, particularly the

pie

chart

depicting the primary

factors

contributing to global

land

degradation

and the

table

displaying how those causes influenced the three regions.
