Is Coffee (Coffea arabica L.) Quality Related to a Combined Farmer–Farm Profile?

Abstract

This study proposed a classification model for 125 agricultural productive units (APUs) in Tolima, Colombia, to establish whether they are related to the quality of coffee produced. The model considered two aspects related to farmer profile and farm profile. The following proposed categories resulted from the coordinate obtained in relation to the two aspects: Low-Low, High-Low, Low-High, and High-High. The variables for each aspect were prioritized using the analysis hierarchical process (AHP). The coffee’s quality, sensory profile by attribute, and specific descriptors for each category were determined employing the Specialty Coffee Association (SCA) protocol. The sensory attributes were analyzed by way of one-way analysis of variance (ANOVA), and the Bonferroni test was used to compare by category, both with a significance level of α = 0.05. The model grouped the APUs by category and cup quality, with the High-High category achieving the best scores in the sensory analysis. The variables with the greatest relative weight within the AHP model constituted farmer stance regarding the use of good agricultural practices (44.5%) and farmer attitude toward excellence (40.6%) in the farmer’s profile. As part of the farm’s profile, environmental commitment level (38.0%) and international certifications (29.1%) were the greatest relative weights. Coffee in the High-High category was characterized by its notes of cinnamon, cocoa, chocolate, and dried vegetables.

The Potential of the Biodigester as a Useful Tool in Coffee Farms

“…These data are related to the concentration of biogas in different coffee farms with their corresponding altitude. The coffee farms shown in Table 3 were selected according to the criteria shown by Bermeo [13]. The concentrations obtained agree with those reported by different authors [14,[34][35][36] for this type of biodigester and fed with pig manure where the altitudes are lower than those reported in this research.…”

“…Taking into account the information gathered, the "Cafés Especiales del Tolima" project transferred Taiwan-type rural biodigesters to a group of coffee growers that were selected based on the criteria presented in the study conducted by Bermeo-Andrade, where coffee growers were classified according to their farmer profile and farm profile [13]. These digesters were used for the suitable processing of wastewater from the coffee process, the generation and use of biol as fertilizer, and the use of biogas in the drying of coffee.…”

Evaluation of Coffee Pulp Waste from Coffee Cultivation Areas in Indonesia as Iron Booster

“…Employing a biogas digester should result in double benefits: a renewable energy source for coffee production (i.e., drying, lighting, power) and organic solid and liquid fertilizers for coffee cultivation (Abdullah et al, 2020;Novia et al, 2021;Setyobudi et al 2021aSetyobudi et al , 2021bSusanto et al, 2020). Various types of the digester are advised by certain experts: Mulato and Suharyanto (2010) utilized a floating drum in Indonesia; Centro Nacional de Investigación del Café (CENICAFE) developed a Modular Anaerobic Treatment System (MATS) for coffee farms in the Colombian mountains (Bermeo-Andrade et al, 2020);Hernández-Sarabia et al (2021) proposed tubular, or bag biodigester (Taiwan type -PVC 1005 geomembrane) in Colombia; Bombardiere (2006) reported the use of thermophilic Continuous Stirred Tank Reactor (CSTR) in Mexico. Rattan et al (2015) suggest Upflow Anaerobic Hybrid Reactor-continuous (UAHR) and intermittent aeration system.…”
