Summary:

In an Ecological Economics article, Gómez, his former student Shadi I. Atallah, and German scientist Juliana Jamarillo consider the viability of sun-grown vs. shade-grown coffee systems. The article:

  • examines the shade cover range for which a coffee farmer is better off under a shade-grown system vs. a sun-grown system;
  • discusses the computational, bioeconomic model developed by the researchers which includes shade-induced pest control services, crop growth services, and timber;
  • finds that expected net present values in the shade-grown system can be higher, but only for shade cover levels between 11 and 34 percent;
  • determines the optimal shading level is 25 percent in a baseline scenario.
