A study conducted at 30 farms has found that the combined effect of birds and bees on coffee bean production surpasses their individual effects. The research demonstrates that without birds and bees, the average yield drops by nearly 25%, equivalent to a loss of around US$1,066 per hectare. This discovery has implications for the $26 billion coffee industry and highlights the importance of biodiversity in agriculture. The study was conducted by an international research team led by Alejandra Martínez-Salinas from CATIE, Taylor Ricketts from the University of Vermont, and Natalia Aristizábal, with support from the US Fish and Wildlife Service. The findings suggest that efforts to calculate the benefits of nature separately may underestimate the value of biodiversity to agriculture.
