Overall, the highest causes of land degradation worldwide because over-grazing, while deforestation is the lowest causes. On the other hand, degradation affect three countries, Europe as the highest and North America as the lowest. Thereover, deforestation does not influence the three continents.

There are four reason why land decrease, over-grazing as the greatest reason that contributes 34% decrease the land. Than, deforestation (30%) and over-cultivation (28%) have a high percentage also that almost have same amount with over-grazing. On the other side, salinization (8%) has a little affect which has huge different values with the others.

There are three region that show the effect of land degradation by over-grazing, deforestation and over cultivation. North Amerika repreresents the highest percentage with over 20% by the three kinds of impact over 5%. Whereover, Europe at approximately 15% with over-grazing as the biggest amounts of effact (10.8%). Whereas, Oceania is the lowest that degradats below 4% as impact.
