Intergenerational Shifts in Ethnobotanical Knowledge of Wild Edible Plants: Why Conservation Matters?

Abstract

Abstract

Wild edible plants play a crucial role in supporting rural livelihoods, yet knowledge about their use remains under documented, particularly among younger generations and across gender lines. This study examined the distribution of ethnobotanical knowledge of wild edible plants across age and gender groups in four municipalities of the Vhembe District, South Africa. Data were collected through semi-structured interviews conducted with 160 participants, primarily in the Venda region. Gendered patterns emerged, where women were more familiar with wild vegetables, while men demonstrated greater knowledge of wild fruits. Promisingly, some female youth demonstrated greater knowledge than older women and male participants. Voucher specimens of the cited plants were verified at the University of Venda Herbarium, and data were analysed using qualitative methods and generalised linear models. Results of this study suggest the need to document and conserve Indigenous knowledge, promote intergenerational knowledge transfer, and empower women and youth in traditional food systems to enhance food security and cultural heritage. The study further provides a foundation for future research on knowledge transmission pathways and supports the development of targeted, community-based conservation and educational initiatives to enhance food security and cultural heritage.
