Breakthrough In Low-Altitude Coffee Cultivation In China Leads To Transforming Eucalyptus Forests Into Arabica Cultivation That Can Meet Specialty Standards – CoffeeTalk

In China, premium coffee cultivation has traditionally focused on the high-altitude regions of Yunnan. Recently, however, a significant development has occurred beneath the eucalyptus forests of Zhanjiang, where Arabica coffee grown at low altitudes is meeting the Specialty Coffee Association (SCA) international standards. This advancement is the culmination of eight years of research led by the Chinese Academy of Forestry’s Institute of Fast-growing Trees. The research team developed a multi-layered forest ecosystem capable of transforming a monoculture plantation into a productive “green gold mine” that sequesters carbon while generating economic value.

The innovative approach involved adjusting eucalyptus planting density and manipulating understory light, temperature, and humidity to enhance the growing conditions for coffee. After extensive screening, the team successfully selected two Arabica varieties suited for local cultivation. The resulting coffee production is now peaking, yielding an impressive 650 kilograms of fresh fruit per mu (approximately 0.16 acres) with beans that conform to SCA standards.

Previously, the land was primarily used for timber, which required many years to mature. In contrast, coffee cultivation now generates an additional annual income of 6,000 yuan for the same area, alongside notable ecological benefits such as enhanced soil quality, water conservation, and increased carbon storage.

The farming initiative has engaged over 90% of local workers from surrounding villages, equipping them with intercropping techniques under the guidance of the research team. This model has shown potential for replication in other low-altitude regions. Beyond coffee production, the team is innovating by developing coffee flower tea, cascara, and specialty fermented coffee utilizing local fruits. They are also exploring value-added processing opportunities for understory mushrooms and medicinal herbs, further establishing a multi-faceted agricultural system.
