The pie chart below shows the main reasons Why agricultural land becomes less productive.The table shows how these causes affected three reguons of the world during the 1919s. Summarise the information by selecting and reporting the main features and make comparison where relevant.

The pie graph provides information about how agricultural

land

would be less productive and the table depicts the causes that affected three regions(North America, Europe,Oceania) during the period of the 1990s.

Overall

, it can be clearly seen that over-grazing was the major percentage of worldwide agricultural

land

degradation

, and Europe was the highest country of

land

degradation

over the shown period. Looking at the

land

degradation

causes in more detail, It is evident that over-grazing was the main reason for worldwide

land

degradation

, accounting for 35%, which was the highest.

Land

decrease for deforestation and over-cultivation were almost similar, at 30% and 28%, respectively. Another cause of worldwide

land

decline was 7%, which was the lowest proportion of the chart. Turning to the

land

degradation

by region data set in more detail, it is clearly seen that Europe was the highest

land

degradation

than others, at 23%. In Oceania, the cause of deforestation accounts for 1.7%, over-cultivation accounts for 0%, over-grazing accounts for 1.3%, and the total

land

degradation

was 13%. North America was merely responsible for 5%, of all categories, which was the lowest country of the three nations.
