The data gives information about the major factors responsible for the infertility of agricultural land and how three different continents were affected by the factors during the period of 1990-1999 inclusive. Overall, it is noticeable that cutting trees down and overgrazing of cattle were two main causes of degradation of land globally. Furthermore, Europe saw the largest area of land eroded and that was mainly due to deforestation. Looking at the data in detail, almost two-fifth of the total degradation was accounted for excessive grazing and clearing trees out jointly with 35% and 30% respectively. Four times as much land was eroded by excessive crop production as opposed to other factors with 7%. In terms of area wise degradation, over one-fifth of the total was recorded in Europe at 23% and the main causing factors were deforestation and over-cultivation at 9. 8% and 7. 7% respectively. Whilst, Oceania was the only continent, in which overgrazing became the main reason of land erosion at 11. 3%.
