Tropical forests are dramatically decreasing. Management practices have also intensified, thus threatening biodiversity. A potential solution is agroforestry, that is the cultivation of shade trees within crops. Scientists Armengot et al. compared agroforestry and classical monoculture. They found that cacao yields were, on average, 41% higher in monocultures, but the revenues derived from agroforestry by-crops economically overcompensated for this difference.
