ABSTRACT Ethnomedicine focuses on empirical and traditional knowledge of healing practices of different human groups, including the use of plants as medicine. We aimed to determine whether there is consensus regarding the use of plants in traditional medicine of Afro-descendant communities in Brazil, Europe and Africa. Data were obtained through interviews, walks-in-the-woods, participant observations and bibliographic searches. We analyzed similarities among data sets to determine whether there is convergence in the use of traditional medicinal plants among these communities considering that they share influence from African culture and a common spoken language (Portuguese). Similarities among communities were assessed through cluster analysis using presence or absence data for the variables. We recorded 405 medicinal plants, most of which were spontaneously occurring, although some were cultivated. The most represented botanical families were Asteraceae and Lamiaceae. Similarity in medicinal plants among communities was found to be tenuous due to the biogeographical and spatial characteristics of the biomes, and to historical and cultural peculiarities of each locality, resulting in different sets of medicinal plants. This study contributes to understanding the role of the historical legacies of the African diaspora and of European (Portuguese) expansion in the adaptation and maintenance of new elements in local floras.

Resumo As estratégias globais no âmbito da CDB são importantes para orientar políticas e recursos para a conservação da diversidade biológica. Este artigo enfatizou a necessidade de desenvolver ações no âmbito da Estratégia Global para a Conservação de Plantas (GSPC) com resultados mensuráveis até 2020, no que se refere ao status e as perspectivas relacionadas às metas 12 e 13, com foco no contexto brasileiro, visando identificar lacunas e ações para alcançar os objetivos para conservação e o uso sustentável das plantas. Salienta-se que a meta 12 abrange também a exploração madeireira, não necessariamente de relação direta com povos indígenas e comunidades tradicionais, porém pode vir a ameaçar seus meios de subsistência. No Brasil, o conhecimento científico sobre os efeitos ecológicos da coleta de produtos florestais não madeireiros ainda é limitado e poucos estudos contribuíram para o estabelecimento de regulamentações legais para coleta e manejo. Com relação à meta 13, que diz respeito aos conhecimentos tradicionais e indígenas sobre o uso de plantas e à dependência desses povos pelas plantas, ainda faltam iniciativas de políticas integradoras e eficazes. No entanto, considerando o contexto político negativo das últimas décadas e exacerbado nos últimos anos, em relação à conservação da biodiversidade e aos povos indígenas e comunidades locais são necessárias mudanças profundas no cenário brasileiro, com forte apoio e reconhecimento para os povos indígenas e comunidades locais, para que qualquer objetivo relacionado ao alcance das metas da GSPC seja minimamente perseguido.

Abstract Global strategies under the scope of CBD are important in guiding policies and resources for the conservation of biological diversity. This paper emphasized the need to develop actions under the Global Strategy for Plant Conservation (GSPC) with measurable results up to 2020, regarding the status and perspectives related to Targets 12 and 13, focusing on the Brazilian context in order to identify gaps and actions to achieve the goals for conservation and sustainable use of plants. It should be noted that Target 12 also covers logging, not necessarily directly related to indigenous peoples and traditional communities, but may threaten their livelihoods. In Brazil, scientific knowledge about the ecological effects of the harvesting of non-timber forest products is still limited, and few studies have contributed to the establishment of legal regulations for collection and management. With regard to target 13, which concerns traditional and indigenous knowledge about plant use and the dependence of these peoples on plants, there are still a lack of integrative and effective policy initiatives. However, considering the negative political context of recent decades and exacerbated in recent years in relation to biodiversity conservation and indigenous peoples and local communities, profound changes are necessary in the Brazilian scenario, with strong support and recognition for indigenous peoples and local communities, so that any objective related to the achievement of the goals of the GSPC is minimally achieved.
