“…So much so, that in Pampa and Patagonia no charcoal-producing species were mentioned. In a study carried out in firewood sale sites in Buenos Aires, charcoal was also sold in 56% of the stores and in all cases it was acquired through purchase (Doumecq, Arenas and Hurrell 2020).…”

“…The redundancy and richness of accessible species throughout the annual cycle seems to be key in areas with scarcity of firewood, such as in the Patagonian steppe (Cardoso et al 2015; Morales, Molares and Ladio 2017). Commercialization allows channels for obtaining species in degraded areas or with difficult access to wood, as has been found in the La Plata riverside, in the Pampas region (Doumecq 2019; Doumecq, Arenas and Hurrell 2020). The domestic sphere as an unavoidable mediator of specific cultural practices linked to the use of firewood, has been highlighted for the Dry Chaco (Martínez 2015; Jiménez-Escobar and Martínez 2019).…”

The use of firewood as an energetic resource in various rural regions of the world is essential for the satisfaction of basic human needs. However, the role of firewood in domestic life and its link to household well-being and food sovereignty have been poorly addressed. In order to investigate these aspects, an ethnobotanical study was carried out in three socio-environmental systems of Argentina ( Chaco, Pampa, and Patagonia). Quantitative and qualitative data were gathered and analyzed. A total of 78 firewood species were recorded. The main use of firewood is for household heating, followed by food preparation and cooking, and lastly for starting and producing home fires. In total 21 firewood species are preferred over others for their various qualities and biophysical attributes, thus becoming of great cultural importance. From different examples and testimonies, we gather that the link between peoples and firewood transcends the mere utilitarian sphere, giving rise to aspects related to the symbolic, emotional, affective, and culinary, among others. These aspects contribute to the well-being of households and communities. In this way, the different firewood species become central in the domestic sphere, not only in terms of their combustion power, but also because of their importance in social, cultural and food life.

“…resulta considerablemente superior -unas dos veces y medio más-que en la Estepa patagónica (Cardoso et al, 2012(Cardoso et al, , 2013Morales et al, 2017) y que en la Puna meridional catamarqueña (Aguirre, 2020). Asimismo, la riqueza en Ancasti es casi el doble que en otras zonas de Catamarca (Gadban, 1999) o que en la Ribera Platense (Doumecq et al, 2020). Si se compara con otras áreas rura-les pertenecientes al Bosque Chaqueño Serrano, pero para la provincia de Córdoba, los resultados son similares a las 56 especies registradas por Martínez (2015) y superiores a las 37 que menciona Fernández (2017).…”

“…En este contexto, algunas plantas que no son nativas de la Sierra, surgen como una alternativa local, ya que en la actualidad esta leña se conoce, se maneja y se utiliza, aunque presente características poco deseables. Varios autores señalan que las especies exóticas por su fácil acceso, mayor disponibilidad, crecimiento rápido y mayor tolerancia que algunas nativas, pueden llegar a cubrir las necesidades básicas de los pobladores y de cierta forma diversificar la oferta de plantas (Morales et al, 2017;Doumecq et al, 2020). Frente a una menor disponibilidad de recursos nativos y una necesidad constante de leña, se genera un aumento en el empleo de plantas exóticas.…”

Antecedentes y Objetivos: La leña constituye una de las principales fuentes de energía de las poblaciones rurales en diversos ambientes y ecosistemas alrededor del mundo. Es una prioridad establecer, desde la mirada local, los principales conjuntos de saberes y percepciones vinculados al uso de este recurso dendroenergético, definiendo los principales términos y categorías relacionados con la leña utilizada en la Sierra de Ancasti, Provincia de Catamarca, Argentina. Métodos: A partir de la técnica “bola de nieve” y por medio de entrevistas abiertas y semiestructuradas en 46 unidades familiares, caminatas guiadas, recolección de ejemplares botánicos, trabajo de herbario y revisión de la literatura, se establecieron las principales percepciones asociadas al uso y conocimiento de especies de leñas. Para obtener las categorías locales de clasificación y términos vernáculos asociados a la leña se propone un “juego de palabras”. Por medio de un diagrama de conjuntos y un Análisis de Componentes Principales (ACP) se identificaron las agrupaciones de especies según las categorías, los términos y las definiciones locales. Resultados clave: Los pobladores señalaron, a partir de 74 nombres comunes, a 53 especies de plantas leñosas que corresponden a 45 géneros y 23 familias botánicas. Destaca el alto porcentaje de especies de origen nativo (74%). En 456 menciones, para 40 especies, se registraron 25 términos relacionados con las propiedades de la madera de las plantas vinculadas con la combustión y el fuego. Los términos más usados por los pobladores para describir y clasificar la leña son: “fuerte” (52 menciones, asociadas a 11 especies), “firme” (39, 13 spp.), “linda” (33, 13 spp.) y “apagosa” (30, 11 spp.). Conclusiones: En la actualidad los pobladores reconocen, describen e identifican la leña utilizando mayoritariamente caracteres que se relacionan con la brasa; destacan como atributos positivos características vinculadas al poder calórico y a la duración. Se enfatiza la necesidad de abordar las dinámicas sociales relacionadas con el medio ambiente desde el propio campo, como una forma de conocer las prioridades locales y canalizar los esfuerzos para la conservación biológica y cultural.

“…Moreover, the importance of wood as the main fuel source for heating and food preparation has been amply shown for rural and peri-urban populations throughout Argentina (Cardoso et al 2015;Doumecq et al 2020a;Martínez 2015;Morales et al 2017;Rodríguez López et al 2015). Therefore, the diversity of species present in domestic areas and involved in rural life are a clear indication of processes of diversification of use, as they not only play different roles, but also satisfy specific and unique needs in the lives of local people.…”

Fuelwood is an essential source of energy for rural populations in many ecosystems. However, little research has addressed the role of exotic species in relation to the use of native woody plants for fuel.This study was performed in rural communities of three ecoregions of Argentina (the phytogeographical provinces of Chaco, Pampa and Patagonia). Basing our study on the diversification hypothesis, we evaluated whether the exotic species used alongside native plants vary in each region. We also studied diversification in relation to gathering environments and use strategies. Open and semi-structured interviews were conducted in 72 households, focusing on the total richness of fuelwood used and its use pressure. We used the ratio between exotic and native richness as an indirect measure of diversification.Data were analysed qualitatively and quantitatively. A total of 78 species was recorded, of which 51 were native and 27 exotic. Gathering is the most common supply strategy in all the ecoregions studied, fuelwood being obtained mainly in sites with little human intervention. A generalized linear model showed that the use of native versus exotic species varied according to the ecoregion and the level of human intervention in the supply area, while acquisition strategies were similar for both native and exotic species in all ecoregions. The areas with most human intervention were always used to gather exotic plants. In line with our hypothesis, UWPF diversification with exotic species varied according to ecoregion. Intrinsic characteristics associated with the history of each region possibly explain the findings.
