Over-gazing and deforestation are following a same pattern in figures with less than a half of proportion of the pie, however, over-cultivation should not be overshadowed by the mentioned issues as it covers 28% of the whole data.
Regarding to table, it is noteworthy that Europe reveals a tendency towards land degradation by holding 23% of the regional disruptive attitude. in terms of deforestation, North America set a record of 0.2% unlike Europe following an ascending order almost close to 10% in that matter. In stark contrast, Oceania experienced a zero percentage of over-cultivation which is completely opposed to Europe by 7.7% suffering from the same issue.
