note = {Tropical hillsides are ecologically and socially diverse with a multitude of small- to medium-sized farms that offer a potential treasure chest of high-value market crops. Specialty coffees, for example, earn a substantial price premium and are therefore a promising opportunity for farmers. Coffee quality is determined by the natural environment and farm management practices. To sell high-priced coffee, farmers must produce beans desired by consumers who are willing to pay more for specific quality profiles. A targeting of the production practices to suit the continuously-changing market demands is necessary; the focus must be on controlling the processes that determine the quality characteristics.
The present research aimed to develop a framework to manage the intrinsic coffee quality of heterogeneous hillside landscapes. In a two-tiered approach, firstly spatial prediction models were developed and tested to identify the comparative advantage of environmental niches and secondly systematic farm management practices were developed and tested to turn the comparative advantage of farmers into a competitive advantage. Commercial sensorial data of the two Colombian departments of Cauca and Antioquia, of the Veracruz department in Mexico and of the five coffee growing regions in Honduras were used to develop and test the framework.
The results suggest that the framework is highly viable; the information generated is highly novel, is high-medium actionable and is medium deliverable to stakeholders. The specific conclusions derived are: (1) The production environment of coffee (natural environment, agronomic management and post-harvest processes) is variable over space. (2) Beverage quality of coffee is dependent on the production environment. The combination of decisive quality factors varies from location to location, and so does the contribution of each factor. (3) Production factors can be identified and their impact quantified. Subsequently the factors can be systematically controlled and managed to improve product quality. (4) Site-specific systematic and cyclic quality control processes are required to decrease produce variability and deliver a product sought by the market. (5) The approach is twofold, firstly the identification of suitable environmental niches followed by definition of site-specific management. (6) Farm management interventions are not always statistically significant but often relevant for farmers. (7) Qualitative quality-control methods using commercial data are viable indicators for quality measurements so long as consistent, skilled evaluators (cuppers) are selected in preliminary testing.},
