The pie chart and the table give information about less productive agricultural land because of several reasons and how influenced to 3 regions of worldwide in 1990. Overall, all of over grazing, deforestation and over cultivation causes significantly to degradation of agricultural land. The highest proportion of effect makes up in Oceania with over grazing. It is clear from the pie-chart that over-grazing by livestock is the most substantial factor in land becoming degraded with 35%. However, the smallest percentage constitutes of other causes at 7% followed by deforestation and over- cultivation at around 29%. According to the table, while the biggest figure comprised with over-grazing at 11, 3% in Oceania, the lowest proportion was just at 0, 2% with deforestation in North America. Moreover, the proportion of degradation from cultivation was higher at 3, 3% in comparison with that of degradation of deforestation at 1, 7% in the countries of North America and Oceania.
