Shade and Agronomic Intensification in Coffee Agroforestry Systems: Trade-Off or Synergy?

Shade and Agronomic Intensification in Coffee Agroforestry Systems: Trade-Off or Synergy?

Despite many years of research, there is still a lack of consensus as to the nature of the relationship between shade trees and agronomic intensification in coffee agroforestry systems. While some studies find unshaded intensively managed coffee is the most productive, other studies find no trade-of...
