Abstract

Firewood is used as a primary energy source in many countries, mainly by human populations in rural and low-income areas. Several factors are associated with the use of the resource, such as the dynamics of preference of groups of plants and socioeconomic issues of families. This study aimed to understand if socioeconomic factors influence the knowledge, use, preference and consumption of firewood in the rural community of Limierinha located near a fragment of Atlantic forest. Semistructured interviews were carried out to obtain socioeconomic data, we performed in situ in two distinct periods of the year, for the quantification of firewood. GLM analyzes were performed to observe if the relationship between the socioeconomic variables influence the knowledge, use, preference and consumption of firewood, we also carried out an estimation of the consumption of wood per capita, by residence and community, in daily, monthly and annual periods . As the main results, we found a total of 87 ethnoespices cited as known for firewood, 47 are used, and 29 preferred, in relation to the richness of known, used and preferred species, the only significant variable was age, while wood consumption Influenced by income, schooling and number of residents in the household. With this, we highlight that the consumption of firewood showed values different from those presented in the literature, and although there is a uniformity in the knowledge of the community residents about the richness of known, used and preferred species, the consumption of firewood (kg) is influenced Socioeconomic factors. In this way, new studies are necessary to understand the present aspects of wood knowledge and consumption, and the influence of socioeconomic variables.
