Network Mapping Interface Analysis between Carbon and Trees Corresponding to Climate Change

Abstract

Background and objective: There have been increasing correlations between the keywords 'carbon' and 'tree' in response to issues related to climate change adaptation. Given this, a study that explores how these keywords relate to issues on climate change adaptation would be significant contribution to the literature. Therefore, this study aims to determine the correlation between these keywords and their network.Methods: To address the aim, the study employed a bibliometric analysis using the VOSviewer software to conduct network-mapping interface analysis using co-occurrence-based visualization and quantification. A two-step approach was applied: the first approach identifies recent driver changes of the keywords 'carbon' and 'tree' and further meaningful keywords. The second approach conducts an in-depth network mapping analysis based on the results drawn by the first approach.Results: The results suggested that, first, 'carbon' and 'tree' were shown to reflect the assessment system and contemporary issues based on the keywords 'carbon sequestration' and 'climate change.' In addition, 'biomass,' 'tree growth,' 'tree ring' and 'trade-off' were shown to be important keywords, which indicated the need for an in-depth correlation analysis. Second, 'biomass' was the key factor in the assessment system for 'carbon sequestration,' in which 'tree growth' and 'tree ring' were included. Third, the network analysis did not report varying results on 'trade-off' compared to 'carbon' and 'tree' with respect to the basic issues on climate change.Conclusion: The conventional assessment system based on the keywords 'carbon' and 'tree' should be improved by incorporating the issues drawn from the keywords 'biomass' and 'trade-off' so that it may reflect the latest contemporary needs. The network analysis on the keywords 'carbon' and 'tree' nevertheless indicated that the two keywords were at the centre of the latest contemporary issues and the assessment system.
