Firstly, the pie chart describes the root cause of the reduction of the productivity of the agricultural land and the latter is the table for the factors that originate the degradation of the land concerning three areas in the 1990s. The pie chart states distinctly that over-grazing brought upon the land degradation the most while the table tabulated that the Europe retained the most degraded land relative to others due to excessive extraction of trees. Other than over-grazing, there are two other crucial objectives for lesser productivity, which are deforestation and over-cultivation that also occupied lesser than a third of the pie chart for each. However, although removal of trees has impact on productivity as much as feeding farm animals of nearly a third of pie chart, it has lower effect on land efficiency than over-grazing by 5%. In terms of destruction on land ability to produce, binge cultivation brought on lesser impact which is a ted of the quarter of the whole. The data from the table point out Europe to be with most land degradation with 23%, twice the amount of that of Oceania which is the second most degraded with 13% during 1990s. Rather, North America suffered the least destruction of land productivity of merely 5% of its overall.
