Analysis of three decades of sugarcane researches focusing on ethanol and bioethanol.

Abstract

Biofuel production from sugarcane has been researched in terms of the environment. Performing a bibliometric method and visual network analysis, the purpose of this study is to assess the trends in sugarcane and bioethanol researches and recognize the associated hotspots based on 4958 publications from 1991 to 2020. The geographical distribution of articles and per capita sugarcane production in the world were also examined. As a widely used database in the field of bibliometric, the Scopus database was used in this research to collect relevant literature. The research method includes the bibliometric analysis of documents and citations, subject categories, journals, countries, institutions, authors, geographical distribution status of articles and annual sugarcane production, top articles. Finally, the social network of the author's keywords was reviewed. The VOSviewer software was used for performing graphic maps showing the co-authorship and communication of countries, authors and keywords. The results show a high growth in the number of published documents in this field and the tendency change from agricultural sciences to environmental sciences in documents and journals. Based on the study's gained results, Brazil is the undisputed leader, publishing 43.8% of the documents in last three decades, followed by the USA and India.
