Agroforestry interventions may act as catalysts for ecosystem service development and changes in supply and therefore may rehabilitate degraded land. This study investigates the trajectories of ecosystem services in coffee systems with a different time since transition to agroforestry in Colombia, the interactions among ecosystem services, and the biotic and abiotic factors that explain them. Therefore, we study a chronosequence of agroforestry coffee farms, with 1–40 years since planting of shade trees. We found that aboveground carbon stock, habitat provisioning, timber volume and coffee bean quality followed positive asymptotic trajectories. Erosion control and pest control did not change over time. Coffee yield tended to decrease as the shade trees matured, but this was not significant. We found consistent positive relationships between carbon stock, erosion control and epiphyte richness. A trade-off between aboveground carbon stock and coffee yield was found for the first 10 years, while a positive relation between coffee yield and erosion control was found for the long term (10–20 years). Canopy cover best explained ecosystem service supply, but also farm agrochemical input management, altitude and slope influenced the supply. This study demonstrated that agroforestry can be used to rehabilitate ecosystem service supply.

40年来哥​​伦比亚咖啡农林业的生态系统服务轨迹

农林业干预措施可以充当生态系统服务发展和供应变化的催化剂,因此可以恢复退化的土地。这项研究调查了自哥伦比亚过渡到农林业以来不同时间的咖啡系统中生态系统服务的轨迹,生态系统服务之间的相互作用以及解释它们的生物和非生物因素。因此,我们研究了农林咖啡农场的时间序列,自种植遮荫树以来已有1–40年。我们发现地上碳储量,生境供应,木材量和咖啡豆质量遵循正渐近轨迹。侵蚀控制和害虫控制没有随时间变化。随着遮荫树的成熟,咖啡产量趋于下降,但这并不明显。我们发现碳储量,侵蚀控制和附生植物丰富度之间具有一致的积极关系。在最初的10年中,发现了地上碳储量与咖啡产量之间的权衡,而在长期(10至20年)中,咖啡产量与侵蚀控制之间存在正相关关系。冠层可以很好地解释生态系统服务的供应,但是农用农药的投入管理,海拔和坡度也会影响供应。这项研究表明,农林业可以用来恢复生态系统服务的供应。而且农用农药的投入管理,海拔和坡度也影响了供应。这项研究表明,农林业可以用来恢复生态系统服务的供应。而且农用农药的投入管理,海拔和坡度也影响了供应。这项研究表明,农林业可以用来恢复生态系统服务的供应。
