Toward the sustainable expansion of the wild edible plant production chain
Myrciaria floribunda (West ex Willd.) O.Berg, commonly known as cambuí , is a wild edible fruit with high socioeconomic potential. However, its value chain remains geographically limited and poorly explored. In this study, we sought to identify bottlenecks and understand how the cambuí ( Myrciaria floribunda (West ex Willd.) O.Berg) value chain is structured in the São Francisco River mouth region, in Northeastern Brazil. A total of 116 local col…
Risk perceptions and adaptive strategies in sociobiodiversity value chains
Environmental changes are at the core of scientific discussions and represent imminent risks to numerous productive activities, including the value chains of sociobiodiversity products. In the face of these risks, local populations develop perceptions and adaptive strategies shaped by their sociocultural contexts. In this study, we sought to identify the factors that explain risk perceptions of environmental changes and adaptive strategies within…
Recife Charter – Pathways for the future of ethnobiology
At the 5th International School of Ethnobiology in Recife (4–5 November 2025), researchers from Brazil and around the world gathered in a spirit of collaboration and shared purpose to envision the future of ethnobiology. This document presents the central agreements and commitments from this transformative meeting, affirming the imperative for an ethnobiology that is theoretically robust, socially relevant, and ethically responsible. The Recife C…
Governance and wild food plant value chains
As an answer to the topic, "Does local, national, and international governance have a primary role in shaping the resilience of local ecological knowledge?" we explore the context of governance and wild food plant (WFP) value chains in Brazil. We chose to focus on WFP value chains because they are often deeply embedded with local ecological knowledge. We argue that: (1) the development or abandonment of public policies can significantly boost or …
Conservation of wild food plants from wood uses
We advocate for biocultural conservation strategies that enhance the food value of plants for their safeguarding, coupled with measures for non-edible woody species under higher use-pressure
Wild food plants with the potential to improve food and nutrition security may be threatened by timber extraction
Wild food plants can contribute to improving the food and nutrition security of local populations by promoting diet diversification and increasing the intake of micro- and macronutrients. However, many of these plants are also used as timber. Wild food species need to be identified and their food–wood use interactions need to be well understood for the development of conservation strategies, as species with the potential to improve food and nutri…
Food Biodiversity as an Opportunity to Address the Challenge of Improving Human Diets and Food Security
Scientists have warned for several years that food systems have become major drivers of environmental degradation, malnutrition, and food insecurity. In this paper, we present arguments from specialists that suggest that, in the transition to more sustainable food systems, biodiversity and food security can be mutually supportive, rather than conflicting goals. We have divided the opinions of these scientists into two "Big Topics". First, they ex…
Use of firewood for artisanal ceramic production in a context of forest scarcity in Northeastern Brazil
In this study, we sought to examine firewood use patterns in artisanal ceramic production by a quilombola community in the context of forest scarcity in Northeastern Brazil. This article aimed to answer the following questions: (1) Is the firing of ceramic products related to the perceived quality, diversity, or plant part used as firewood? (2) Does the diversity of plants used as firewood vary according to the age and gender of artisan potters? …
Sampling Bias in Ethnobotanical Studies on Medicinal Plants Conducted in Local Markets
Studies have identified the strong presence of sampling bias in ethnobiological research, which may seriously compromise study results. However, these studies were made in the context of Brazilian studies and global sampling evaluations are still needed. The present study adopted a global scale and was based on ethnobotanical surveys of medicinal plants in open fairs and markets. We aimed to assess sample quality and to identify the factors that …
Experiências De Popularização De Plantas Alimentícias Não Convencionais No Estado De Alagoas, Brasil
Os seres humanos vêm restringindo a diversidade de alimentos em sua dieta ao longo dos anos, devido ao processo de globalização dos sistemas agroalimentares. Neste sentido, a promoção da popularização de plantas alimentícias não convencionais (PANC) pode ter importantes implicações nutricionais, ecológicas e socioeconômicas. Neste artigo buscamos descrever algumas estratégias de popularização das PANC no Estado de Alagoas realizadas pelo Laborató…
Use Categories and Local Perception of Decline in Plant Populations
Local criteria for the selection of wild food plants for consumption and sale in Alagoas, Brazil
Understanding the reasons for the consumption of certain plant resources instead of others has important implications for biological conservation. This study aimed to answer the following question: What are the factors that determine the consumption and perceived commercial potential of certain wild fruit species among extractivists from two rural communities in northeastern Brazil? This study developed a participatory approach to identify the fr…
Factors that influence human behavior in biofuel use and their implications for biocultural conservation
A set of investigations has attempted to identify patterns in human resource use behavior to drive conservation strategies. However, it is still necessary to advance the understanding of the factors that influence human decision making in the use of resources, considering the perceived cost-benefit relationships. In this research, we assessed whether cost-benefit rationale may explain why certain resources are more used than others, as well as th…
Does Forest Scarcity Affect the Collection and Use of Firewood by Rural Communities? A Case Study in the Atlantic Forest of Northeastern Brazil
They call me a woodsman
Woodsmen or "mateiros" are people who are commonly hired or contracted to work as special local collaborators, often guiding scientists inside the forest, providing local names of plants and other useful information. We interviewed forest researchers and woodsmen to unveil the process of forest science production in the coastal zone of Northeast Brazil. The concept of network is used as a basis for discussing the connections involving forest know…
Plant extractivism in light of game theory
BACKGROUND: Game theory enables the predictive study of the behavior of agents that recognize the mutual interdependence of their decisions and act rationally and strategically to maximize their own gains. In this paper, the extractivism of pequi (Caryocar coriaceum Wittm.) and fava d'anta (Dimorphandra gardneriana Tul.) in an area of common use of the semiarid region of northeastern Brazil is described as a model to illustrate a practical applic…
A new technique for testing distribution of knowledge and to estimate sampling sufficiency in ethnobiology studies
Background We propose a new quantitative measure that enables the researcher to make decisions and test hypotheses about the distribution of knowledge in a community and estimate the richness and sharing of information among informants. In our study, this measure has two levels of analysis: intracultural and intrafamily. Methods Using data collected in northeastern Brazil, we evaluated how these new estimators of richness and sharing behave for d…
