The pie chart demonstrates the reasons that led to global land degradation and the table attached compares some statistics of three different regions, damaged from the land degradation in 1990.

Obviously, the most harm to the land was from overgrazed animals. It was most sensible in islands of Oceania.

The percentage of the harm from over-cultivation was a bit higher than a quarter percent. Deforestation, by contrast, caused to 30% land degradation. The rest items that prompted land degradation were overgrazing(35%) and other negligible factors(7%)

0.2% of North America’s lands suffered from deforestation while about 10% of European terrains were degraded by it. Though, this number in Oceania was 1.7% of total land degraded. Over-cultivation and grazing cost North America 3.3% and 1.5% of total damaged lands, which was 5%. However, this rate in Europe was 7.7% and 5.5% respectively with 23% land affected in sum. Having lost 13% of lands Oceania struggled with 11.3% degraded lands and interestingly did not suffer from over-cultivation
