近年来，荫咖啡认证计划越来越受到保护和发展组织的关注。认证计划提供了一个机会，通过向生产者提供溢价，将环境和经济目标联系起来，从而促进森林保护。然而，由于缺乏经验证据，认证计划的保护工作的意义仍然不清楚。本研究的目的是研究的影响，树荫咖啡认证计划对森林保护。该研究在埃塞俄比亚Belete Gera区域森林优先区进行，并利用2005年和2010年的遥感数据来衡量森林面积的变化。使用倾向得分匹配估计，我们发现，咖啡认证计划下的森林不太可能被砍伐森林比森林咖啡。相比之下，有森林咖啡但没有认证计划的森林与没有森林咖啡的森林之间的毁林程度差异在统计上是微不足道的。这些结果表明，认证计划对森林保护产生了很大的影响，将森林砍伐的可能性降低了1.7个百分点。
In recent years, shade coffee certification programs have attracted increasing attention from conservation and development organizations. Certification programs offer an opportunity to link environmental and economic goals by providing a premium price to producers and thereby contributing to forest conservation. However, the significance of the conservation efforts of certification programs remains unclear because of a lack of empirical evidence. The purpose of this study was to examine the impact of a shade coffee certification program on forest conservation. The study was conducted in the Belete-Gera Regional Forest Priority Area in Ethiopia, and remote sensing data of 2005 and 2010 were used to gauge the change of forest area. Using propensity score matching estimation, we found that forests under the coffee certification program were less likely to be deforested than forests without forest coffee. By contrast, the difference in the degree of deforestation between forests with forest coffee but not under the certification program and forests with no forest coffee is statistically insignificant. These results suggest that the certification program has had a large effect on forest protection, decreasing the probability of deforestation by 1.7 percentage points.
