Research trend of rice and greenhouse gases based on Web of Science: a bibliometric analysis

Abstract

Based on the Web of Science core database and using bibliometric analysis method, this study analysed 2,680 papers on rice and greenhouse gas topic research till to 22 July 2022, which included 47 highly cited papers and one hot paper, mainly written in English and from 10,116 authors, 2,594 organisations and 111 countries or territories, published in 517 journals and four book series. The top five journals are Science of the Total Environment, Journal of Cleaner Production, Agriculture and Ecosystems Environment, Environmental Science and Pollution Research and Sustainability. The top five countries were Peoples R China, U.S.A., India, Germany and Japan. The top five organisations were the Chinese Academy of Sciences, Nanjing Agricultural University, Indian Council of Agricultural Research, CGIAR and Chinese Academy of Agricultural Sciences, each with more than 126 papers. The top four authors were Wassmann Reiner, Pan Genxing, Smith Pete and Cao Cougui. All keywords were separated into 10 clusters with co-occurrence network visualisation using VOSviewer, and the research front was shown by co-occurrence overlay visualisation. The results will help researchers clarify the current research situation, but also provide guidance for future research in rice and greenhouse gases.
