The pie chart and table compare and contrast data of the influence of three key factors namely, deforestation, over-grazing, over-cultivation on the land productivity.
Overall, over-grazing is considered the main cause of land degradation around the world. Among the continents, Europe ranks first, where observes the highest percent of soil deterioration.
According to the data, 35 % of worldwide land was suffering because of over-grazing development, while deforestation made up 30 % and took the second place among the main reasons. On the third place was over-cultivation, which was slightly less than deforestation and accounted 28 % of all lands.
Also, noteworty is the fact that in Europe these 3 key factors had the most negatively effect on the land productivity. Approximately 10 % European land degradateed by cut down forests, while in North America it took only 0, 2 %. If in Europe over-cultivation destroyed 7, 7 % of land squares, in Oceania this index equaled zero. However, in Oceania over-grazing took the leader position among the main factors of land destroying and total 11, 3 %, while North America stood last and made up 1, 5%.
