Cabo Verde's biodiversity is threatened by activities that meet human needs. To counteract this, an integration of scientific and indigenous knowledge is required, but no comprehensive list of the useful local plants is available. Thus, in this work, we assess (1) their diversity and phytogeography; (2) the role of geophysical, historical, and socio-economic factors on species distribution and uses; and (3) potentially relevant species for sustainable development. Data were obtained from flora, scientific publications, historical documents, herbarium specimens and field work. Many species were introduced since the 15th century to support settlement and commercial interests. We identified 518 useful taxa, of which 145 are native, 38 endemic and 44 endangered. The number of useful taxa is correlated with altitude and agricultural area, as well as with rural population indicators, but not with total population or socio-economic indicators such as gross domestic product. Native taxa are mostly used for fuelwood, forage and utilitarian purposes. Agrobiodiversity and traditional practices seem crucial to cope with recurrent droughts and ensure food security. Most of the introduced species do not present conservation problems, contrasting with the overuse of some native taxa. The safeguarding of native populations will ensure the sustainable exploitation of these resources and benefit the local economy.
佛得角的生物多样性受到满足人类需求活动的威胁。为应对这一情况,需要将科学知识与本土知识相结合,但目前尚无有用本地植物的完整清单。因此,在这项工作中,我们评估:(1)它们的多样性和植物地理学;(2)地球物理、历史和社会经济因素对物种分布和用途的作用;(3)对可持续发展具有潜在相关性的物种。数据来源于植物志、科学出版物、历史文献、标本馆标本和实地调查。自15世纪以来,为了支持定居点建设和商业利益,引入了许多物种。我们识别出518个有用的分类单元,其中145个是本土的,38个是特有种,44个是濒危种。有用分类单元的数量与海拔、农业面积以及农村人口指标相关,但与总人口或国内生产总值等社会经济指标无关。本土分类单元大多用于薪柴、饲料和实用目的。农业生物多样性和传统做法似乎对于应对反复出现的干旱以及确保粮食安全至关重要。与一些本土分类单元的过度使用形成对比的是,大多数引入物种不存在保护问题。保护本土物种将确保这些资源的可持续利用,并使当地经济受益。
