气候变化对咖啡生产产生了不利影响，影响了产量和品质。咖啡生产以种植阿拉比卡和罗布斯塔咖啡为主，这两种咖啡占产量的99%，但两者都会受到气候变化的影响。由于生产支撑着全球2500多万人的生计，其中大多数是位于热带咖啡带的小农，因此迫切需要能够增强生产和生计对气候变化的抵御能力的可持续管理实践。这些社区已经经历了气候变化的影响。我们进行了系统回顾，确定了80项研究，这些研究描述了气候变化对咖啡农业生态系统的直接和间接影响，或者确定了具有增强气候适应能力潜力的农业生态实践。不利的环境影响包括适合生产的面积减少、产量下降、极端气候事件的强度和频率增加以及病虫害发生率增加。潜在的环境解决方案包括海拔垂直变化、新的、有弹性的品种、改变农用化学品投入和农林业。然而，财政、环境和技术方面的制约因素限制了许多这些方法对农民，特别是小农生产者的可用性。因此，迫切需要通过政策和市场机制以及利益相关者的参与来解决这些障碍，以继续满足不断增长的咖啡需求。
ABSTRACT Climate change is adversely affecting coffee production, impacting both yields and quality. Coffee production is dominated by the cultivation of Arabica and Robusta coffee, species that represent 99% of production, but both will be affected by climate change. Sustainable management practices that can enhance the resilience of production and livelihoods to climate change are urgently needed as production supports the livelihoods of over 25 million people globally, the majority of whom are smallholder farmers located in the coffee belt spanning the tropics. These communities are already experiencing the impacts of climate change. We conducted a systematic review, identifying 80 studies that describe the direct and indirect impacts of climate change on coffee agroecosystems, or that identify agroecological practices with the potential to enhance climate resilience. Adverse environmental impacts include a reduction in area suitable for production, lower yields, increased intensity and frequency of extreme climate events, and greater incidence of pests and diseases. Potential environmental solutions include altitudinal shifts, new, resilient cultivars, altering agrochemical inputs, and agroforestry. However, financial, environmental and technical constraints limit the availability of many of these approaches to farmers, particularly smallholder producers. There is therefore an urgent need to address these barriers through policy and market mechanisms, and stakeholder engagement to continue meeting the growing demand for coffee.
