The given pie chart and table illustrate the major reasons that caused to decrease in the productivity of the soil and how much North America, Europe, and Oceania's land were degraded by them in 1990, respectively.
Overall, deforestation and over-grazing were a contributing factor in agricultural land degradation as well as farmlands of Europe faced the most proportion of destruction in 1990. Generally, each of the factors' effect was notable in Europe, unlike the two other regions.
Regarding the pie chart data, over-grazing had the most effect on land by 35%, and the demise of forests was the second greatest impact on it. In addition, worldwide lands destroyed by excess cultivation accounted for 28 percent. Other factors made up 7%.
Turning to the table, the proportion of the effect of each of the detrimental factors on the productivity of the soil in different lands were between zero and 11. 3%. Totally, Europe's lands were degraded by a third, by comparison, North America's by 5%, as the lowest percentages, and Oceania by 13%. Whilst the main factor in decreasing productivity in Europe was the destruction of forests (9. 8%), Oceania suffered over-grazing which possessed the maximum percentage. Similarly, over-cultivation did not have a role in degradation in Oceania, on the contrary, it was a core reason, 3. 3%, in North America.
