What affects the sustainability of a non-timber forest product value chain? A case study of an endemic palm harvested by local communities in Brazil.
Article in Journal of ethnobiology and ethnomedicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTraditional harvest of non-timber forest products (NTFP) offers an economic alternative to local communities by providing income without significantly altering current land use while reinforcing deeply rooted local knowledge. Analyzing NTFP value chains helps understand the actors, relationships, stages, and sustainability of these products. This study focuses on the piassava palm (Attalea funifera Martius), examining its value chain structure, social and economic indicators, and sustainability challenges.
methodsOur study focused on communities in the Environmental Protection Areas of Pratigi and Tinharé-Boipeba in Bahia, Brazil. We examined five local communities involved in piassava harvesting, using semi-structured interviews and participant observation to gather data on actor roles, socioeconomic aspects, and sustainability issues, like economic vulnerabilities, social challenges, and environmental threats. Using a mixed-methods approach-combining semi-structured interviews, participant observation, and quantitative descriptive analysis-we investigated the roles of key actors, relationships, and threats within the piassava value chain. Findings were analyzed using content analysis and basic statistical measures to understand the social, environmental, and economic dimensions of sustainability.
resultsWe observed diverse stages, actor roles, and final products in the piassava value chain, identifying three primary raw materials: fibers, leaves, and fruits. Four main stages were noted: harvest, transportation, fiber separation, and product sales, with ecotourism emerging as a potential stage in the value chain analyzed here. The piassava value chain's structure varies based on the materials and products involved, with key actors being harvest workers, partitioners, roofing artisans, and handicraft artisans. Respondents identified 20 threats to the piassava value chain, categorized into economic, social, and environmental issues, with the most cited being the scarcity of harvest workers, lack of interest among young people, and deforestation, respectively.
conclusionsOur results suggest policy recommendations for reconciling social, economic, and ecological aspects. These include promoting community-based tourism as a complementary income source. Recognizing and disseminating piassava value chain outcomes as sociobiodiversity products, for example, strengthening legal and commercial frameworks to certify piassava products, or encouraging investment in local processing infrastructure to enhance value addition and market access. Finally, the results analyzed here underscore the importance of including local perspectives in discussions and highlight the need for further research to evaluate strategies for sustainable community forest management.
