The pie chart below shows the main reason why agriculutural land become less productive. The table shows how these causes effected three regions of the world during the 1900s

This

provided chart illustrates the essential causes that result in a reduction in the production of agricultural

land

in three different places.

Overall

, it can be seen that there were four main factors, which degraded the

land

in the three provided contents, but the

land

of

Oceania

was only affected by two of them.

To begin

, the highest percentage of

land

deterioration occurred in Europe, at 23%, which was about four times more than in North America.

In addition

to that, the accountability of deforestation for

land

deterioration was, at 30% which made it the second reason. Even though forest demolition was the primary reason for

land

degradation in Europe, at 9.8%, it was the least factor that harm the

land

in the other two locations.

Although

over-grazing accounted for 35% of

land

degradation, it was considered the

last

factor in Europe that ruined the

land

, at 5.5%, and it was the first harmful reason to the Earth in

Oceania

, at 11.3%.

Furthermore

, over-cultivation was responsible for 28% of

land

damage,

hence

; it was the biggest factor that degraded the

land

in North America, but it did not have any detrimental effect on the

land

in

Oceania

.

Finally

, the total degraded

land

in

Oceania

was 13%

whereas

it was 5% in North America. And there were some other reasons for

land

deterioration which represented 7%.
