Beyond genetics × environment interaction on quality drivers of Arabica coffee: a review of implication for Gedeo indigenous agroforestry systems under changing climates

Indigenous agroforestry systems play a pivotal role in producing high-quality Arabica coffee by modulating microclimatic conditions, soil carbon, moisture, and nutrition regimes, thereby enhancing coffee adaptability to changing evapotranspiration patterns. This review synthesizes findings from 114 studies on genetics, environmental factors, management practices, and socioeconomic drivers of coffee quality and productivity in Gedeo Cultural Landscape. While climate and environment are traditionally seen as key markers of coffee quality, established management systems—such as shade tree integration and farmer practices—equally influence outcomes. Socioeconomic factors, including technology adoption, market access, infrastructure, and extension services, further shape production standards. The study underscores the need for maintaining specific edaphic-climatic interactions alongside robust management frameworks to sustain quality coffee production under shifting climatic conditions.
