Fairly consequential minorities of the three reasons were attributable to the global degraded land with numbers standing at 35 percent of over-grazing, 30 percent of deforestation and 28 percent of over-cultivation. It is apparent that over-cultivation was the least prevalent category among others.
Turning to the table informing the causes of land erosion in three regions, namely North America, Europe and Oceania, it is evident that the unimpressively highest figures for land degradation was seen in Europe with a fairly mere 23 percent, of which deforestation was the most dominant factor with a number of just north of 3 percent. It was with figures for Oceania that one sees a greater proportion of over-grazing then deforestation with numbers of just north of 11 percent for the first and well north of 1 percent of the latter. The picture as far as North America was concerned was substantially different as a consequence of the fact that it was the least vulnerable to land degradation with a negligible 5 percent. Among three reasons listed on the table, over-cultivation was by far the most commonplace driver of the rough land around the globe.
In an overall tendency that cannot escape notice, a modest minority of over-grazing led to the degradation of the global land.
