The main factors responsible for the decreased productivity of agricultural

land in North America, Europe, and Oceania during the 1990s were summarized in a

pie chart and a table.

the most serious problem was over-grazing. It has caused the world to lose

35% of agriculture land. This problem is followed closely by deforestation and

over-cultivation.

The area that has lost most proportion of its agriculture land was Europe at

23% However, Oceania and North America was not as badly affected, losing 13% and

5% of its farmland respectively.

Surprisingly, the main problem faced by each area is different from one

another. The problem with over-grazing is especially serious in Oceania,

resulting in 11.3% of its land unsuitable for agriculture. On the other hand,

deforestation that caused 9.8% of agriculture land unusable was the major

problem faced by the European farmers. Although over-cultivation was the primary

threat in North America, it was not a problem at all in Oceania.

In conclusion, over-grazing was the main cause of worldwide degradation in

1990s. Europe’s percentage of degradation was largest of all three regions and

all three regions had different predominant causes.
