Traditional knowledge and ethnobotanical uses of wild soursop (Annona senegalensis Pers.) in three agroecological zones of Côte d'Ivoire
摘要
Wild soursop (Annona senegalensis) is a wild fruit shrub producing non-timber forest products of great socioeconomic and medicinal value. This study assessed the cultural importance and local knowledge of the species across three communities in Côte d’Ivoire: Koumokro, Pouniakélé, and Kouassi N’Dawa. A semi-structured survey was conducted among 289 informants to collect data on sociodemographic characteristics, traditional knowledge (vernacular names, uses, harvesting methods), and factors affecting the species’ survival. Ethnobotanical indices were used to analyze the data. Results revealed that local populations have extensive knowledge of and actively use the species, primarily for food and medicinal purposes. A total of 34 specific uses of the different plant parts were identified, obtained through both sustainable and destructive harvesting practices (cutting, uprooting, debarking, picking). Regression analysis showed a significant association between age and traditional knowledge levels. The types of use varied significantly between communities. However, the commercialization of plant organs and human activities such as gold panning and grazing threaten the species’ regeneration and long-term sustainability. These findings highlight the crucial role of traditional knowledge in guiding conservation and sustainable management strategies for culturally important species like wild soursop.
