“…Yang et al (2021) explained that Chlorophyll has a direct effect on the process of photosynthesis, namely producing organic compounds as assimilates derived from inorganic compounds with the help of sunlight. These organic compounds are needed by a plant in its metabolic process (plant height, number of leaves, leaf area, and yield) (Adugna Debela Bote & Jan, 2016;Chalchissa et al, 2022;Damatta et al, 2008;Praxedes et al, 2006). This argument is proven in the research results, that the increasing value of SHC is in line with the increase in the production of coffee plants.…”

Coffee is one of the primary sources of foreign exchange in Indonesia. The factors causing fluctuations in coffee production are climate change, high soil density, less organic material, which causes coffee roots to be unable to absorb water and nutrients optimally. The soil water movement measured by saturated hydraulic conductivity which represents the soil ability to transmit water. The application of compost and manure in the biopore infiltration hole (BIH) is an effective technology in reducing surface-runoff and organic wastes management, as well as soil characteristics improvement. This study was conducted using a Randomized Block Design with four treatments and four replications. The treatments were P1 as control (without BIH), P2 (BIH without compost), P3 (BIH+compost), and P4 (BIH+goat manure). Data analysis was carried out using the Ftest (ANOVA), and continued with Least Significant Difference (LSD) test at 5% level, when there was a significant difference. Observations of soil characteristics were carried out every two months in three depth of root zone, 0-20 cm, 20-40 cm, and 40-60 cm. While the observation of the Auger hole at a depth of 0-30 cm and 0-60 cm. Research variables include soil texture, soil bulk density, Saturated Hydraulic Conductivity of soil by Auger-Hole, Soil Organic Matter (SOC), pH, Cation Exchange Capasity (CEC), and coffee yield. Results showed that treatment of BIH+goat manure gave the best results, measured by improving soil hydraulic conductivity up to 40%. The highest coffee yield was found in the BIH+manure treatment to 3.29 t ha-1.

“…The method presented in Ref. [ 68 ] was used to calculate changes in soil parameters as changes in extreme climate indicators using equation (3) .

where ΔSP% indicates the percent change in the soil parameters (soil pH and Al 3+ ), PSP is the predicted soil parameter, i is the average soil pH or Al 3+ , and HSP is the historical value of the soil parameter.…”

“…Generalised Regression Models (GRM) are applied globally to assess the impact of Vapour Pressure Development (VPD) on Arabica coffee yield. In Ethiopia, GRM evaluated the influences of extreme agroclimatic indicators on Arabica coffee's overground biomass (AGB) until 2060 [13,82].…”

Several modelling tools reported the climate change impact on the coffee agrosystems. This article has adopted a systematic approach to searching out information from the literature about different modelling approaches to assess climate change impacts or/and adaptation on coffee crops worldwide. The review included all scientific publications from the date of the first relevant article until the end of 2022 and screened 60 relevant articles. Most results report research conducted in America, followed by Africa. The models assessed in the literature generally incorporate Intergovernmental Panel on Climate Change (IPCC) emission scenarios (80% of manuscripts), particularly Representative Concentration Pathways (RCP) and Special Report on Emission Scenarios (SRES), with the most common projection periods until 2050 (50% of documents). The selected manuscripts contain qualitative and quantitative modelling tools to simulate climate impact on crop suitability (55% of results), crop productivity (25% of studies), and pests and diseases (20% of the results). According to the analysed literature, MaxEnt is the leading machine learning model to assess the climate suitability of coffee agrosystems. The most authentic and reliable model in pest distribution is the Insect Life Cycle Modelling Software (ILCYM) (version 4.0). Scientific evidence shows a lack of adaptation modelling, especially in shading and irrigation practices, which crop models can assess. Therefore, it is recommended to fill this scientific gap by generating modelling tools to understand better coffee crop phenology and its adaptation under different climate scenarios to support adaptation strategies in coffee-producing countries, especially for the Robusta coffee species, where a lack of studies is reported (6% of the results), even though this species represents 40% of the total coffee production.
