农林业干预措施可作为生态系统服务发展和供应变化的催化剂，因此可恢复退化的土地。本研究探讨了生态系统服务的轨迹在咖啡系统与不同的时间，因为过渡到农林在哥伦比亚，生态系统服务之间的相互作用，以及生物和非生物因素，解释它们。因此，我们研究了农林咖啡农场的时序，自种植遮荫树以来有1-40年。我们发现，地上碳储量，栖息地供应，木材体积和咖啡豆质量遵循积极的渐近轨迹。侵蚀控制和虫害控制并没有随着时间的推移而改变。咖啡产量随着遮荫树的成熟而下降，但这并不显著。我们发现碳储量，侵蚀控制和附生植物丰富度之间存在一致的正相关关系。在第一个10年，地上碳储量和咖啡产量之间的权衡，而咖啡产量和侵蚀控制之间的正相关关系被发现为长期（10-20年）。冠层覆盖最能解释生态系统服务供给，但农用化学品投入管理、海拔和坡度也影响着服务供给。本研究表明，农林复合系统可用于恢复生态系统服务供给。
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.
