How Climate Change Impacts the Value Chain of Caryocar Coriaceum Wittm.: Gatherers’ Perceptions in Northeastern Brazil

Objective: This study aims to investigate the value chain of C. coriaceum and the climate-related challenges faced by gatherers in Northeastern Brazil, in order to understand how climate change affects both production and socio-economic relations along the chain. Theoretical Framework: The research is grounded in the concepts of non-timber forest product value chains, socio-environmental sustainability, and the impacts of climate change on the phenology of Neotropical species, highlighting the relevance of local perceptions as a complement to scientific evidence on water and heat stress in plants. Method: A mixed-methods approach was employed, combining qualitative and quantitative data through semi-structured interviews with 17 sellers/gatherers. To map and analyze the C. coriaceum value chain, the Value Links 2.0 approach was used to structure supply, processing, and distribution levels. Gatherers’ perceptions of climate impacts were analyzed through narratives and storytelling, allowing an understanding of how experiences, emotions, and socio-ecological relationships shape management practices and adaptive responses to climate change. Results and Discussion: The results indicate that the C. coriaceum value chain is highly seasonal and dependent on external suppliers before the local harvest (December–February). Informal relationships between gatherers and traders characterize the harvest period, with an average profit margin of 57.13%. Gatherers reported negative impacts of climate change on fruit size and taste, attributed to changes in rainfall patterns, elevated temperatures, and frequent wildfires. These perceptions align with scientific evidence on water and heat stress affecting the species’ phenology. Research Implications: Findings highlight both socio-economic and environmental challenges in the C. coriaceum value chain, emphasizing the need for organizational strengthening and adoption of sustainable practices to enhance local community resilience. Originality/Value: The study integrates local knowledge and scientific evidence on climate change impacts, providing insights for public policy and sustainable management strategies for native species.
