North America exhibited the lowest. In terms of international proportions, animal-related land pressure accounted for 35% of total depletion, narrowly exceeding forest loss (30%) and intensive cultivation (28%). The remaining 7% was attributed to less common sources, rendering them relatively insignificant. The tabular data shows that Europe’s total soil deterioration reached 23%, mainly

logging (9.8%) and recurrent planting (7.7%). Oceania followed with 13%, the bulk of which (11.3%) stemmed from grazing-related stress, with no loss reported from over-cultivation.
