The estimated planted forest model with the quadratic term projects increasing global planted forest area trends for the next three to four decades with declining trends thereafter. This outcome is consistent with the view that rising incomes are associated with progressively greater attention to the adverse environmental or social impacts of planted forests. For instance, depending on assumed socioeconomic futures, the projected gains in global planted forest area ranged from 9% to 14% by 2055, which were projected to decline thereafter, representing no increase to a 3% increase by 2100 compared to the 2015 level.
