Replication data for: Farmer attitudes and intentions towards trees in cocoa (Theobroma cacao L.) farms in Coˆte d’Ivoire

Cocoa yields in Coˆte d’Ivoire are low and falling each year, partly as a result of full-sun cropping systems. Thus, interest is now high in establishing sustainable cocoa agroforestry systems through the reintroduction of shade trees. This article uses data collected from a sample of 400 cocoa farmers in the Soubre´ region of Coˆte d’Ivoire to analyze farmers’ current and intention to plant trees in their cocoa farms in the future and the motivation for their decision. Logit regressions are used to assess the various determinants of current tree planting behaviour and future adoption intention. Results show that both current and likelihood of deliberately planting trees with mcocoa in the future is significantly affected by extension and certification programs, severity of diseases affecting cocoa, and geographic zone. Future intentions to associate trees with cocoa are further influenced by the age of the farmers, household size and the average age of the cocoa farm. To increase the adoption of tree planting in cocoa fields there is the need to intensify extension messages on the benefit of shade trees in cocoa farms especially in areas where adoption intention is still low. Where awareness is high, adoption can be increased through the suppl y of seedlings and provision of specific trainings on planting density and management techniques to ensure that agroforestry has the maximum positive effect.

科特迪瓦（Côte d’Ivoire）的可可产量本就偏低且逐年下滑，其部分成因在于全日照种植模式。因此，当前学界与产业界对通过重新引入遮荫树构建可持续可可农林业（agroforestry）系统的关注度显著提升。本文依托从科特迪瓦苏布雷（Soubré）地区400名可可种植户的抽样调查中获取的数据，分析了当前种植户在可可园中种植树木的现状，以及未来在可可园中套种树木的意向及其决策动机。研究采用逻辑回归（Logit regressions）模型，评估了当前植树行为与未来种植意向的各类影响因素。结果表明，当前已在可可园中套种树木，以及未来有意套种树木的概率，显著受到农业推广项目、认证项目、可可病害严重程度以及地理区域的影响。未来与可可树套种树木的意向，还进一步受到种植户年龄、家庭规模以及可可园平均树龄的影响。为提升可可园植树的推广采用率，需强化关于可可园种植遮荫树益处的推广宣传，尤其在种植意向仍较低的地区。在公众认知度较高的地区，则可通过供应种苗、开展针对种植密度与管理技术的专项培训，确保农林业系统发挥最大的正向效益。
