The pie chart indicates that there are 4 main reasons for land degradation in the world. The first main reason is over-grazing with 35%. The second is deforestation. In fact cutting down the trees induces 30% land degradation. The third reason related to over-cultivation which participate 28% in degradation. The other 7% estimated for other causes.
Based on the table, the impacts of these 3 main causes differentiated on different regions during the 1990s. Over-grazing had the biggest role in Oceanian lands (11. 3%) while it had only 1. 5% effect on North American lands.
In addition, deforestation caused degrading in Europe about 9. 8%, however, this amount was only 0. 2 and 1. 7 in North America and Oceania respectively.
Furthermore, although over-cultivation had not any role in Oceania degradation, 7. 7% of European degradation occured by this reason.
In conclusion, Europe had the most land degradation in 1990s with 23% in total. Oceania and North America with totally 13% and 5% of degradation were stand in next.
