Distribution and Transmission of Medicinal Plant Knowledge in the Andean Highlands: A Case Study from Peru and Bolivia

This paper presents a study of patterns in the distribution and transmission of medicinal plant knowledge in rural Andean communities in Peru and Bolivia. Interviews and freelisting exercises were conducted with 18 households at each study site. The amount of medicinal plant knowledge of households was compared in relation to their socioeconomic characteristics. Cluster analysis was applied to identify households that possessed similar knowledge. The different modes of knowledge transmission were also assessed. Our study shows that while the amount of plant knowledge is determined by individual motivation and experience, the type of knowledge is influenced by the community of residence, age, migratory activity, and market integration. Plant knowledge was equally transmitted vertically and horizontally, which indicates that it is first acquired within the family but then undergoes transformations as a result of subsequent contacts with other knowledge sources, including age peers

Are the Young Less Knowledgeable? Local Knowledge of Natural Remedies and Its Transformations in the Andean Highlands

A widespread concern among ethnobiologists is the rapid process of erosion of indigenous environmental knowledge observed worldwide. This paper examines the ongoing transformations of knowledge about natural remedies in the Quechua-speaking Andes. Freelisting exercises and interviews were conducted with 36 households at Bolivian and Peruvian study sites. (Generalized) linear mixed-effects models were used to analyze the effects of age on knowledge about medicinal plants, animals, minerals, and their uses. Our study demonstrates that younger participants knew as much about natural remedies as their elders. However, proportional knowledge about some medicinal use categories of natural remedies varied with age. We conclude that knowledge about natural remedies is generally not being lost at the study sites. Nevertheless, it is undergoing transformations in terms of specific medicinal uses. A careful understanding of these complex transformation processes is needed to better orient initiatives for the conservation of biocultural diversity in the Andes and elsewher

Mountain Research and Development Embarks on Its Fifth Decade

Editorial

Focus issue: pastoralism and rangelands in mountains

Mountain rangelands (open grasslands, mixed forest meadows, closed forests, and alpine lakes and wetlands) play vital roles for humans, supporting livestock grazing, hunting, and harvesting of plants. They thus provide livelihoods for a large number of rural mountain communities across the globe. These systems are also key for water supply to lowland areas and watershed health, carbon sequestration and storage, fire regulation, and, increasingly, recreational use and tourism. They are vital for the conservation of mountain species and habitats, including endemic species and habitats exclusive to mountains. Many of these ecosystems require management to maintain species diversity and productivity and supply a range of high-quality ecosystem services.info:eu-repo/semantics/publishedVersio
