Bibliometric analysis of ethnobotanical research in Brazil (1988-2013)

This study aimed to define the current status of ethnobotanical research in Brazil based on published scientific articles and to detect current knowledge gaps in Brazil's ethnobotany. A database, including articles published in national and international scientific journals from 1988 to 2013, was gathered for this purpose. This report discusses the growing number of publications in ethnobotanical research and the main techniques used in the discipline. To identify current knowledge gaps, his report emphasizes the main focus of the different studies, target regions, and communities targeted or involved in the original study. Most publications focused on the northeast and southeast Brazil, and the most frequently studied biomes were the Caatinga and Atlantic forest. Further, the most frequently studied communities were located in rural areas, although the number of studies focused in urban areas has been steadily increasing. A lack of human resources in ethnobotanical research and a lack of current studies in the Amazon, Cerrado, Pampa, and Pantanal regions were the main identified gaps. These data provide a basis for future studies and investments aimed at strengthening ethnobotanical research in Brazil.
