Coffee agroforestry systems provide ecosystem services, the quality of which depends on the management carried out by coffee farmers. This study evaluated the provision of four ecosystem services (maintaining habitats, improving water quality, erosion control, and carbon stocks) on certified and non-certified coffee farms. We studied 30 coffee agroforestry systems located in Turrialba and Orosi using three different certification systems (Utz-Rainforest Alliance, Nespresso, Organic) and some without certification. Certified coffee agroforestry systems provide more ecosystem services than non-certified ones; however, on some non-certified coffee farms, different activities that provide ecosystem services were performed. Of the coffee farms evaluated, certified Organic farms had the highest conservation activities.

咖啡农林业系统提供生态系统服务，其质量取决于咖啡农进行的管理。这项研究评估了在经过认证和未经认证的咖啡农场中提供的四种生态系统服务（维持生境，改善水质，控制侵蚀和碳储量）。我们使用三种不同的认证系统（Utz-Rainforest Alliance，Nespresso，Organic）研究了位于Turrialba和Orosi的30种咖啡农林业系统，其中一些未经认证。经过认证的咖啡农林业系统比未经认证的咖啡农林业系统提供更多的生态系统服务；但是，在一些未经认证的咖啡农场，开展了提供生态系统服务的不同活动。在所评估的咖啡农场中，认证的有机农场的保护活动最高。
