Produção científica sobre resíduos de poda urbana: uma análise cienciométrica

Abstract

Urban afforestation provides several ecosystem services to humans, such as improved air quality and thermal comfort. However, when it comes to tree residues from pruning, complex activities are necessary, especially when it comes to the correct destination and/or reuse of such residues. Therefore, a scientometric analysis of studies on the reuse of pruning residues, published between 1991 and 2020, was performed. The analyzed studies were obtained through advanced searches in the Scopus and Web of Science databases. 607 studies were analyzed, the main authors, institutions and countries researching pruning residues were identified, the Bradford Law was applied to the visualization of the main journals. The keywords were also analyzed using a co-occurrence network and thematic mapping to visualize the main themes and research trends. It was observed that Spanish researchers and institutions were influential in the analyzed scientific field, which placed Spain in the first position in number of publications. 28 journals were considered core, or core for publications on pruning residues, publishing 1/3 of all studies. The most frequent research topics were biomass, compost, biochar and bioenergy. The main driving themes, fundamental to publications on pruning residues, were bioenergy, renewable energy, urban biomass residues and allometric relationships. Scientometrics proved to be an efficient method for measuring and understanding the total number of publications that address urban pruning residues.
