Turning to specific regions, around a quarter of the world’s degraded was allocated at Europe, while this percentage approximately as doubled as Oceania, which they were 23% and 13% in order. Meanwhile, North America was 5% of total land degraded, and the over-cultivation was the largest reason for them by 3.3%.
