“…This can be expressed in trying and experimenting plants, and recognizing the value of new resources (Medeiros et al 2012). The knowledge systems are also affect ed by adaptation to the new environments, since people may create strategies of use and acquisi tion of plant resources (Medeiros et al 2012). In this sense, plant cultivation in familiar areas, such as homegardens, can figure as an important alter native to knowledge and resources maintenance.…”

Homegardens are conservation units for native plants and reservoirs of exotic species from different origins. We analysed the species composition and diversity of edible plants on three groups of homegardens in a gradient from urban to rural situations, but under the same historical and cultural contexts, and verified how these homegardens can favour the conservation of plants from different origins. The size of each homegarden was measured and complete inventories were carried out to assess the total edible plant diversity. Plants were collected for taxonomic identification or identified in the field, and were classified for their biogeographic origin. We compared species richness and diversity among the groups of homegardens (urban, periurban and rural), and analysed their floristic similarity. A total of 109 homegardens were studied (39 urban, 60 periurban, and 10 rural). We registered a total of 101 species, 45 botanical families and 41 varieties, with 71% of the species occurring in less than 10% of the homegardens. Rural homegardens were more diverse than periurban ones, and periurban and urban homegardens are equally diverse. We found a low but significant correlation between floristic similarity and geographic distance to the urban area. Most plants were introduced, with different origins, especially from South America Lowlands. A significant amount of plants were exchanged between relatives and neighbours. These homegardens can be considered agrobiodiversity reservoirs in a micro-regional scale, being important areas for in situ and on farm conservation and including native and exotic plants.

“…Because not all plants are found everywhere, the floristic environment constrains plant use. The adaptation of traditional medicine when migrations expose cultures to new floristic environments may occur through horizontal transmission of plant use and homogenization of practices [21][22][23]. In this study, we focus on 12 moderately to closely related ethnic groups from Nepal.…”

The evolution of traditional knowledge: environment shapes medicinal plant use in Nepal

et al. 2014

Traditional knowledge is influenced by ancestry, inter-cultural diffusion and interaction with the natural environment. It is problematic to assess the contributions of these influences independently because closely related ethnic groups may also be geographically close, exposed to similar environments and able to exchange knowledge readily. Medicinal plant use is one of the most important components of traditional knowledge, since plants provide healthcare for up to 80% of the world's population. Here, we assess the significance of ancestry, geographical proximity of cultures and the environment in determining medicinal plant use for 12 ethnic groups in Nepal. Incorporating phylogenetic information to account for plant evolutionary relatedness, we calculate pairwise distances that describe differences in the ethnic groups' medicinal floras and floristic environments. We also determine linguistic relatedness and geographical separation for all pairs of ethnic groups. We show that medicinal uses are most similar when cultures are found in similar floristic environments. The correlation between medicinal flora and floristic environment was positive and strongly significant, in contrast to the effects of shared ancestry and geographical proximity. These findings demonstrate the importance of adaptation to local environments, even at small spatial scale, in shaping traditional knowledge during human cultural evolution.

“…Several studies have examined the use of medicinal plants by migrant groups (Balick et al 2000;Capps 2009;Ceuterick et al 2008;Medeiros et al 2012;Nesheim et al 2006;Pieroni and Gray 2008;Volpato et al 2009). Systematic reviews can contribute to clarification of information such as the main strategy used by migrants (to obtain plants from their original habitat or to adapt themselves to new plants) or how migration results in the increase or reduction of medicinal plants available in the new habitat.…”
