This study aims to provide a simple framework to identify wild food plants with potential for popularization based on local knowledge and perception. To this end, we also characterized the distribution of this knowledge in the socio-ecological system. We developed the study in the rural settlement Dom Hélder Câmara in northeastern Brazil. The species with the greatest potential for popularization considering the attributes accessed from local knowledge and perception were Psidium guineense Sw., Genipa americana L., Xanthosoma sagittifolium (L.) Schott and Dioscorea trifida L.f. However, the high variation in local knowledge on wild food plants suggests that species that are not frequently cited can also be promising. The absence of age or gender-related knowledge patterns indicates that studies for prospecting wild food plants in similar socioecological contexts need to reach the population as a whole, rather than focusing on a specific group.
本研究旨在提供一个简单的框架，根据当地知识和认知来识别具有推广潜力的野生食用植物。为此，我们还描述了这种知识在社会生态系统中的分布。我们在巴西东北部的农村定居点 Dom Hélder Câmara 开展了这项研究。根据从当地知识和认知中获取的属性，具有最大推广潜力的物种是 Psidium guineense Sw.、Genipa americana L.、Xanthosoma sagittifolium (L.) Schott 和 Dioscorea trifida L.f. 然而，野生食用植物的当地知识存在高度差异，这表明不常被提及的物种也可能具有前景。在野生食用植物方面，年龄和性别与知识之间没有关联，这表明在类似的社会生态环境中进行野生食用植物研究需要面向全体居民，而不是集中在特定群体。
