“…The results showed areas that have the potential for Gayo Arabica coffee cultivation which were then superimposed with a spatial pattern map to ensure that the area is not included in protected areas. (3) The potential map based on the cultivated area was superimposed on a land-use map (coffee garden map) for the GH to obtain the GI area that has been planted on. Meanwhile, climate change analysis that has a direct impact on the Gayo arabica coffee management was carried out through (1) analysis of rainfall for a period of 100 years (1910 -2009) based on 10 and 30-year classification and (2) analysis of available air temperature data for 40 years (1970 -2009).…”

“…Therefore, the Gayo Arabica coffee GI reflects a system that relates to the production areas (site-specific), traceable producers/farmers (local wisdom), and unique and high-quality products from an area (traceable products). Based on this system, the coffee has a good quality, reputation (fame), and other essential characteristics that are closely related to its geographical origin [3].…”

Geographical Indications of Gayo Arabica coffee is currently faced with various challenges, including climate change, causing stagnation and, eventually, a decline in productivity. This research aims to determine the strategies adopted by farmers in dealing with climate change, to increase and maintain Gayo coffee productivity. The research was conducted in the Gayo Highlands, particularly in Aceh Tengah, Bener Meriah, and Gayo Lues districts, in three stages, including; (1) a study of the Gayo coffee GI area, (2) climate change study, and (3) a study of farmers’ strategies for dealing with climate change, using field observation surveys and interviews with farmers. The results reveal that the GI of Gayo arabica coffee has been mapped since its designation in 2010. Additionally, both rainfall and temperature have changed since the 1980s, and climate change (particularly temperature) has resulted in habitat shifting for the cultivation of arabica coffee clones, coffee berry borer infestations, and a decrease in coffee productivity. Farmers in the Gayo Arabica coffee GI area address climate change by implementing a strategy to create a microclimate through adaptation and mitigation. These include efforts to adapt coffee clones to their growing habitat, creating a microclimate by planting coffee and denser shade, covering the soil surface to minimize evaporation, and reducing the concentration of carbon dioxide gas and greenhouse gas emissions in the air by using locally sourced organic matter as fertilizer.

Soil nutrients influence all stages (reproduction, growth, and development) of a plant species’ life, and it is known that the deficit and/or toxicity of one or more nutrients has negative effects on the production of crops of commercial interest. Ecuador represents one of the “mega-diverse” countries in the world, with an agricultural sector of great importance, due to its contribution to the country’s economy. This review provides a panoramic view of soil nutrients from different climatic regions of Ecuador and revises the importance of knowledge about the possible influence of nutrients from the soil on the plant metabolism able to influence the crop resistance against pathogens or to enrich the biological characteristics of these crops.

“…The Gayo Highlands, The plantations, which have long been recognized as a hub for the production of arabica coffee in Aceh Province, are now also noted for their production of citronella. Dry land in the Gayo Highlands is mostly dominated by citronella and pine merkusii [4]. The results of the study [5] noted that in the Gayo Highlands, Gayo Lues Regency, there were 13,765.75 ha of a total of 160,017.17 ha allocated for cultivation land that had been planted with citronella by farmers.…”

This research tries to identify the chemical state of the soil in the existing citronella planting area in the Gayo Highlands based on altitude, slope, and soil type. The method used in this research is the descriptive method, with data collected through field surveys and laboratory analysis. Soil samples were taken at each observation point by a purposive sampling method, which was determined based on the components forming a homogeneous land unit consisting of six (6) elevation classes, five (5) slope classes, and five (5) soil types. The results of the analysis showed that the highest value of C-organic was found at location Land Unit 6 (LU6) altitude above 1,200 meters above sea level (m asl), which was 7.29%, and the lowest value was found at location LU1 (200-400 m asl), which was 0.81%. While the highest variation of CEC values was found at locations LU6 and LU3 (600-800 m asl) with a value of 56.40 cmol kg−1, the lowest was found at locations LU1. The citronella cultivation area in the Gayo Highlands was studied based on altitude, slope, and soil type at each observation point. It is still suitable to be developed as a citronella cultivation area where the value of soil chemical characteristics found at each research location is in the low to very high criteria and the pH criteria are in the acid to slightly alkaline criteria.
