“…Therefore, direct N 2 O emissions from the coffee plants in the botanical garden were estimated as 5.013-10.1 Kg CO 2 eq yr −1 and for the coffee plantations as between 487-990 Kg CO 2-eq yr −1 . If we compare these results, they do not differ from other studies, where they show, in general, total GHG emissions for Arabica coffee processing of 1.804 t CO 2 -eq yr −1 [59]. It has been estimated that a coffee plantation possesses 1.02 kg of CO 2 e/kg of green coffee [23].…”

The main source of N2O emissions is agriculture, and coffee monocultures have become an important part of these emissions. The demand for coffee has increased in the last five decades. Thus, its production in agricultural fields and the excess of fertilizers have increased. This study quantified N2O emissions from different dose applications and types of nitrogen fertilizer in a region of major coffee production in Costa Rica. A specific methodology to measure N2O fluxes from coffee plants was developed using Fourier-transform infrared spectroscopy (FTIR). Measurements were performed in a botanical garden in Germany and plots in Costa Rica, analyzing the behavior of a fertilizer in two varieties of coffee (Catuai and Geisha), and in a field experiment, testing two types of fertilizers (chemical (F1) and physical mixture (F2)) and compost (SA). As a result, the additions of synthetic fertilizer increased the N2O fluxes. F2 showed higher emissions than F1 by up to 90% in the field experiment, and an increase in general emissions occurred after a rain event in the coffee plantation. The weak levels of N2O emissions were caused by a rainfall deficit, maintaining low water content in the soil. Robust research is suggested for the inventories.

“…Data with the same trend are found by Colaço et al (2012) [15] when they evaluated the VR treatment in wheat and obtained higher EROI values compared to the values obtained with the UR treatment. [40] estimated Energy Balance and Green House Gas Emission on Smallholder Java Coffee Production of Indonesia, the results showed that the energy value obtained for the arabica coffee transportation and production were 152.36 MJ t −1 and 74.54 MJ t −1 , respectively, while the robusta coffee had an energy value of 158.68 MJ t −1 and 162.74. MJ t −1 , respectively.…”

Coffee is a crop of great relevance in socioeconomic terms for Brazilian agribusiness, which is the world’s largest producer in cultivated areas. The implementation of precision agriculture in the coffee culture has provided countless benefits to its development, which over the years has been cultivated in the same area. However, there is a lack of studies that address the impact of the application of variable-rates inputs in soil on the energy efficiency and sustainability of these systems. This study aimed to analyze how variable-rate fertilization influences energy efficiency in coffee growing. A production area subjected to variable and fixed rates of fertilizer in alternating rows was evaluated. Geo-referenced yield data was collected to assess yield response for fixed and variable rate applications. The energy assessment was combined with the Geographic Information System (GIS) to determine site-specific energy indicators. To determine the energy flow, only NPK fertilizer applications were considered as inputs and the yield as output. The results obtained indicated that the variable rate fertilizer application has a small difference, indicating greater energy efficiency concerning the applied fertilizer and coffee production per crop season. It was observed in the 06/07 crop, the incorporated energy was 10.7 MJ kg−1 for VR and 10.2 MJ kg−1 for UR and for the 07/08 crop it was 30.7 MJ kg−1 for VR and 34.9 MJ kg−1 for UR. The energy balance was more efficient at variable rates, as it provided fertilizer savings without compromising yield. However, the difference between the embodied energy per mass of coffee produced was very small compared to the fixed rate.

“…Agroforestry of coffee has the potential for carbon sequestration (Goodall et al, 2015) and provides socio-economic advantages from wood and fruit plants (Pinoargote et al, 2016). Harsono et al (2021) utilize energy balance and green house gas emission calculation and found the potential measures to replacing gasoline with biofuel, utilising liquid waste with chemical processing, and solid wastes (briquettes and bio-pellets) of coffee production for renewable energy. Another study evaluated the net balance of GHG by including agroforestry potential in N mineralization and N fixation (Hergoualc'h et al, 2012).…”

Carbon dioxide (CO2) in the atmosphere occurs as the result of various chemical, physical, and biological processes. The presence of CO2 around atmosphere greatly affects the agroforestry and agroindustry of coffee. This study aimed to describe the CO2 cycle in agroforestry and agroindustry of Gayo Arabica coffee (Coffea arabica) and net CO2 ha -1 of coffee plantation. CO2 cycle was analyzed based on the movement of CO2 around the agroforestry and agroindustry of coffee. CO2 cycle model describes net CO2, CO2 emission, CO2 reduction, and CO2 sequestration. Net CO2 ha -1 of coffee plantation was 162.75 × 10 -2 t CO2 e ha -1 , with CO2 emission was 203.84 × 10 -2 t CO2 e ha -1 , CO2 reduction was 3.10 × 10 -2 t CO2 e ha -1 , and CO2 sequestration was 363.49 × 10 -2 t CO2 e ha -1 . This research formulates the calculation of equivalent carbon emissions in the arabica coffee production system in the field and primary processing, using various methods (remote sensing analysis and calculation of direct and indirect equivalent carbon emissions). The CO2 cycle positively impacts the sustainability of agroforestry and agroindustry of Gayo Arabica coffee.
