Show moreComparing Apples and Pears: The Hidden Diversity of Central African Bush Mangoes (Irvingiaceae). The fruits of Irvingiaceae trees, commonly known as "bush mangoes" or "mangues sauvages," are crucial foods for Central African human populations, as well as local wildlife. Irvingiaceae oil-rich kernels play an important role in local diet, well-being, and livelihood. When collected for sale, they enter the international market of non-timber forest products (NTFPs), which represents a considerable source of income for central African countries. Despite the importance of bush mangoes, there is a general lack of precision in the literature on the exact species of Irvingiaceae present in local diets and NTFP markets. Few botanical studies include local names and uses of the different Irvingiaceae species, while ethnographical and social studies rarely corroborate their identifications by collecting vouchers. In this study, we combined ethnographic research and botanical collection to verify which Irvingiaceae species were consumed and collected for trade by the Baka, a group of forager-horticulturalists in southeastern Cameroon. We provide evidence of the floristic diversity hidden behind the term "bush mangoes", as well as the knowledge and uses of Irvingiaceae fruits by the Baka. We discuss the importance of eight Irvingiaceae species for Baka livelihood as well as the potential threats regarding the future of these valuable trees. Show less

Show moreIncreasing deforestation affects tropical forests, threatening the livelihoods of local populations who subsist on forest resources. The disappearance of wild plants and animals and the increasing influence of market economies affect local health, well-being, and diet. The impact of these changes on wild meat consumption has been well documented, but little attention has been given to wild edible plants, despite their importance as sources of calories and micronutrients. Furthermore, the relationships among food behavior strategies adopted by local populations, their psycho-cultural representations of food, and their food preferences have been poorly explored. In this study, we investigate food behaviors with an emphasis on the role of wild edible plants among a forager-horticulturalist society from the Congo Basin: the Baka. By combining an ethnobotanical survey with data from interviews (n = 536) related to food behaviors and representations of food, our data show that the Baka valorize both agricultural and marketable foods, and that wild plants represent a minor part of their diet, both in frequency and diversity. Finally, by examining how some wild edible plants have shifted from being eaten to being sold, we explore how market-oriented uses of wild edible plants may affect dietary behaviors and biocultural resilience.

Show moreThe Historia Naturalis Brasiliae (HNB, 1648) is the most complete treatise on Brazilian flora and fauna created in the seventeenth century. Scientists Marcgrave and Piso depicted hundreds of plants and described uses, vernacular names, and diseases in Dutch Brazil. We aimed to verify whether these plants are still used similarly, using herbarium vouchers and taxonomic literature to identify the species described in the HNB and reviewing historical and modern ethnobotanical literature to analyze whether the HNB documented specific plants and uses for the northeast region. We highlighted Old World species, as they indicate plant introduction before and during the trans-Atlantic slave trade and exchange of African ethnobotanical knowledge. Of the 378 species found in the HNB, 256 (68%) were useful, mostly used for healing and food in a similar way (80%) both in the seventeenth century and in modern Brazil. Only one species (Swartzia pickelii) is endemic to northeast Brazil, while the others are more widely distributed. The HNB includes one of the first reports on African crops in Brazil, such as sesame, okra, and spider plant. This study brings insights on indigenous and African plant knowledge retentions since the creation of the HNB and acknowledges its non-European contributors. Show less
