The current expansion of cacao cultivation in the Republic of Côte d’Ivoire is associated with deforestation, forest degradation, biodiversity loss and high greenhouse gas (GHG) emissions. Global concerns about emissions that are associated with tropical commodity production are increasing. Consequently, there is a need to change the present cacao-growing practice into a more climate-friendly cultivation system. A more climate-friendly system causes lower GHG emissions, stores a high amount of carbon in its standing biomass and produces high cacao yields. GHG emissions and carbon stocks associated with the present cacao production, as assessed in 509 farmers’ fields, were estimated by using the Perennial GHG model and the Cool Farm Tool. On average, the production of 1 kg cacao beans is associated with an emission of 1.47 kg CO2e. Deforestation contributed largely to GHG emissions, while tree biomass and residue management contributed mainly to carbon storage. The collected data combined with the model simulations revealed that it is feasible to produce relatively high yields while at the same time storing a high amount of carbon in the standing biomass and causing low GHG emissions. The climate-friendliness of cacao production is strongly related to farm management, especially the number of shade trees and management of residues. Calculated emissions related to good agricultural practices were 2.29 kg CO2e per kg cacao beans. The higher emissions due to the use of more agro-inputs and other residue management practices such as recommended burning of residues for sanitary reasons were not compensated for by higher yields. This indicates a need to revisit recommended practices with respect to climate change mitigation objectives.

模拟科特迪瓦共和国可可生产的温室气体排放

目前科特迪瓦共和国可可种植的扩大与森林砍伐、森林退化、生物多样性丧失和温室气体 (GHG) 排放量高有关。全球对与热带商品生产相关的排放的担忧正在增加。因此,有必要将目前的可可种植实践转变为更加气候友好的种植系统。一个更加气候友好的系统可以降低温室气体排放量,在其生物质中储存大量碳,并产生高可可产量。使用 Perennial GHG 模型和 Cool Farm Tool 估算了与当前可可生产相关的温室气体排放和碳储量,在 509 个农田中进行了评估。平均而言,生产 1 公斤可可豆会排放 1.47 公斤二氧化碳2 e。砍伐森林在很大程度上促成了温室气体排放,而树木生物量和残留物管理主要促成了碳储存。收集的数据与模型模拟相结合表明,在产生相对较高的产量的同时,在常设生物质中储存大量碳并导致低温室气体排放是可行的。可可生产的气候友好性与农场管理密切相关,尤其是遮荫树的数量和残留物的管理。与良好农业实践相关的计算排放量为 2.29 kg CO 2e 每公斤可可豆。由于使用更多的农业投入物和其他残留物管理做法(例如出于卫生原因推荐燃烧残留物)导致的较高排放量并没有被更高的产量所补偿。这表明需要重新审视有关减缓气候变化目标的推荐做法。
