Tendências de pesquisa sobre tratamento de dejetos da suinocultura: uma análise bibliométrica

Abstract

Pig farming has been a major activity for the world economy, due to the considerable increase in production over the years. Brazil is the fourth largest pork producer in the world. Thus, production is directly proportional to the amount of pig manure, making this activity a potential polluter. In this way, wastewater from swine farming that is discharged without treatment has an impact on natural resources. The objective of this research was to carry out a bibliometric analysis of published works on the treatment of swine manure, in order to analyze the technological advances and evolution of knowledge related to the subject. As a method to elaborate the research, searches were carried out in the Scopus database, strategically, with keywords related to the theme, which facilitated the subsequent refinement. Then, relevant data on studies in countries, categories, journals, institutions, authors and the trends of the theme were selected and examined in Excel, for the construction of graphs and tables. The VOSviewer software was intended to build interaction networks, maps and clusters, with data and information (authors, countries, institutions, keywords) obtained from the Scopus database. Therefore, through the results it was evaluated that the field of study is still expanding, it was possible to verify the highest peak of publications over the years, recognize the main authors on the subject, the main countries that addressed pig farming, the evolution of keywords over the years and so it was noted what has changed since the beginning of research related to the topic until the present day.
