The pie chart shows the main reason why agricultural land becomes less productive. The pie chart shows the main reason why agricultural land becomes less productive.

The data presents the root causes of the decrease in

land

in the world and the proportion in each region. There is a pie chart that shows the type of the degradation reasons.

In addition

, there is a table containing the

percentage

of

land

degradation caused by region. The diagram illustrates

land

degradation's reasons

such

as deforestation, over-cultivation, and over-grazing. Over-grazing has the highest

percentage

as a disertification cause in the amount of 35%. Followed by deforestation has a

percentage

of 30%.

Then

, the third cause is over-cultivation which has a

percentage

of 28%. The other 7% are others that could not be defined.

Next,

the table gives us information about the distribution area of the desertification reason.

Firstly

, Europe has the highest

percentage

of

land

degraded amounting to 23% which 9.8% is caused by deforestation.

Secondly

, Oceania (a large group of islands in the South Pacific including Australia and New Zealand) take the second position with 13% amount in which 11.3% of

land

degraded was caused by over-grazing. The

last

, North America has total

land

degraded amounted to 5% and 3.3% caused by over-cultivation.
