Advancing ethnobiology for the ecological transition and a more inclusive and just world: a comprehensive framework for the next 20 years.

This opinion piece, written by ethnobiologists from different parts of the world, emphasizes the importance of ethnobiology research in advancing contemporary biology, natural resource management, biodiversity conservation, sustainable development, and, especially, contributing to the ecological transition and more just and inclusive world. To achieve these goals, it is essential to develop research and collaborate with social groups that live in close relationship with nature in research activities, such as Indigenous Peoples and Local Communities (IPLC), as well as Afro-descendants and other Marginalized, Minority or Minoritized Communities (AMMC). Ethnobiology can identify and provide locally appropriate solutions to local problems, enabling sustainable resource management at the landscape level. The text explores important aspects that need to be considered to guide the future of ethnobiology in the next 20 years, aiming to integrate and amplify previous discussions held in the discipline and identify points that demand ongoing attention. This paper highlights reflections from diverse researchers, emphasizing how ethnobiology can embrace different perspectives and employ rigorous analysis of complex phenomena toward effective policies and practices. This approach holds the potential to address the challenges the planet is currently facing in the coming decades.

Plantas andinas y sus productos comercializados con fines medicinales y alimentarios en el área metropolitana Buenos Aires-La Plata, Argentina / ndean plants and its products commercialized for food and medicinal purposes in the metropolitan area Buenos Aires-La Plata, Argentina

Este trabajo incluye 50 taxones (especies, subespecies, variedades, cultivares) de plantas vinculadas al acervo andino, cuyos productos se comercializan con fines alimentarios y terapéuticos en el Área Metropolitana Buenos Aires-La Plata, Argentina. Para cada taxón se indican sus productos, los usos asignados y sus efectos científicamente estudiados, a los fines de evaluar su correlación. Asimismo, se discute su difusión desde el ámbito restringido del segmento de inmigrantes bolivianos (contexto "ligado a tradiciones") hacia el circuito comercial general (contexto "no tradicional"). De este modo, la dinámica del conocimiento botánico local es evaluada a través de la circulación de distintos productos.

This paper includes 50 taxa (species, subspecies, varieties, cultivars) of plants linked to the Andean context whose products are marketed for food and medicinal purposes in Metropolitan Buenos Aires-La Plata, Argentina. For each taxon its products are indicated, as well as its assigned uses and scientifically studied effects, in order to evaluate their correlation. Also, the products diffusion from the restricted ambit of the Bolivian immigrants segment (‘linked to traditions’ context) to the general commercial circuit (‘not traditional’ context) is discussed. Thereby, the dynamics of local botanical knowledge is assessed through the different products circulation.

Del marco tradicional al escenario urbano: plantas ancestrales devenidas suplementos dietéticos en la conurbación Buenos Aires-La Plata, Argentina / From traditional frame to urban scenario: Ancient plants became dietary supplementsin conurbation Buenos Aires-La Plata, Argentina

This paper includes partial results of a research in urban Ethnobotany at the conurbation Buenos Aires-La Plata, Argentina. Five species with medicinal and food traditional uses, which are commercialized as dietary supplements were studied: Annona muricata L. (Annonaceae), Euterpe oleracea Mart. (Arecaceae), Lycium barbarum L. (Solanaceae), Plukenetia volubilis L. (Euphorbiaceae) y Smallanthus sonchifolius (Poepp. & Engl.) H.Rob. (Asteraceae). The analysis of the circulation of these products contributes to the understanding of local botanical knowledge, that includes nontraditional components and others linked to the traditions of two immigrant groups: Bolivian and Chinese. The products recently entered the commercial circuit where they are considered as nutraceuticals and adaptogens. Traditional uses of these plants, their properties claimed in pluricultural urban context as well as the scientifically studied ones were compared. Thus, modifications in the original uses as a result of the expansion of the products in the nontraditional commercial context were evaluated.

Este trabajo comprende resultados parciales de una investigación en Etnobotánica urbana en la conurbación Buenos Aires-La Plata, Argentina. Se estudiaron cinco especies con usos medicinales y alimentarios tradicionales, comercializadas como suplementos dietéticos: Annona muricata L. (Annonaceae), Euterpe oleracea Mart. (Arecaceae), Lycium barbarum L. (Solanaceae), Plukenetia volubilis L. (Euphorbiaceae) y Smallanthus sonchifolius (Poepp. & Engl.) H.Rob. (Asteraceae). Al analizar la circulación de los productos se aporta a la comprensión del conocimiento botánico local, con sus componentes no tradicionales y ligados a las tradiciones de dos grupos de inmigrantes: bolivianos y chinos. Los productos ingresaron recientemente en el circuito comercial, donde se consideran nutracéuticos y adaptógenos. Se comparan los usos tradicionales de las plantas, las propiedades difundidas en el contexto pluricultural urbano y las científicamente estudiadas. De este modo, se evaluaron las modificaciones de los usos originales, como resultado de la expansión de los productos en el contexto comercial no tradicional.

Leguminosas medicinales y alimenticias utilizadas en la conurbación Buenos Aires-La Plata, Argentina / Medicinal and alimentary legumes utilized in the conurbation Buenos Aires-La Plata, Argentina

This contribution includes the results of a study within Urban Ethnobotany about those Legumes employed with medicinal and food purposes in the biggest conurbation of Argentina: Greater Buenos Aires-Greater La Plata. Plants, parts of them and derived products were evaluated. Products that circulate in diverse shops of the area correspond to 32 taxa. Those are catalogued as products with generalized diffusion (present in the general commercial circuit), restricted diffusion (restricted to groups of Bolivian and Asians immigrants taken as reference) and expanding diffusion (species which products are passing from restricted to general circuit, from their access in health stores called “dietéticas”). Besides, the paper includes 35 taxa native and adventitious in the area, that have been recorded as food and medicine, and 36 taxa cultivated as ornamental, that are employed in other regions –but not in the study area– with therapeutic and food purposes. These results contribute to the definition of urban botanical knowledge here presented, as a complex corpus that includes traditional and non traditional components. Likewise, they contribute to the study of the dynamics of this knowledge, expressed by those plant products that are in expansion in the commercial circuit.

Este trabajo incluye los resultados de un estudio de Etnobotánica urbana sobre las Leguminosas utilizadas con fines medicinales y alimentarios en la mayor conurbación de la Argentina, que comprende el Gran Buenos Aires y el Gran La Plata. Se evaluaron plantas, partes de las mismas y productos obtenidos a partir de ellas. A 32 taxones corresponden productos que circulan en diversos comercios del área, catalogados como de difusión generalizada (circuito comercial general), restringida (a grupos de inmigrantes bolivianos y asiáticos tomados como referencia) y en expansión (especies cuyos productos pasan del circuito restringido al general, a partir de su ingreso en los comercios llamados “dietéticas”). Además, se incluyen 35 taxones nativos y adventicios del área con registro de usos terapéuticos y alimentarios; y 36 taxones cultivados como ornamentales, empleados en otras regiones para la alimentación y con fines medicinales, pero no utilizados en el área. Estos resultados contribuyen a la definición de conocimiento botánico urbano aquí presentada, en tanto conjunto complejo que incluye componentes tradicionales y no tradicionales; asimismo, aportan al estudio de la dinámica de dicho conocimiento, que se expresa en los productos vegetales que se hallan en expansión dentro el circuito comercial.
