Small-scale coffee farmers' perception of climate-adapted attributes in participatory coffee breeding: A case study of Gayo Highland, Aceh, Indonesia

Small-scale coffee farming in Indonesia faces low productivity due to poor farming practices and low-quality planting materials. It highlights the need for improved coffee varieties that meet farmers' preferences. Given the vulnerability of coffee farming to climate change, participatory breeding programs that involve collaboration between researchers and farmers to develop a climate-adapted variety are essential. This study used survey data from Gayo Highland, Aceh, Indonesia, to investigate farmers' perception of the importance of climate-related attributes in a coffee variety, including those developed through a participatory breeding program, and the determinant factors. The result shows that farmers rated climate-related attributes as the least important (average score 0.36) compared to others, such as coffee productivity (1.57) and quality (1.22), resistance to pests and diseases (0.96), and input-use efficiency (0.57). This finding suggests a lack of awareness among farmers about the importance of climate issues in coffee farming. The estimation results also indicate that coffee extension activities have a negative association with farmers' perceptions of the importance of climate attributes. This study recommends inclusive and targeted climate campaigns to increase farmers' concern, awareness, and knowledge about the threats of climate change to coffee farming through strengthening advisory services.
