Bibliometric analysis of scientific research on biochar

Abstract

Objective: To identify the most relevant aspects of global scientific research on biocharin terms of number of articles published, main authors and publishing countries, citation,subjects of scientific journals, funding institutions and general trends.Design/Methodology/Approach: A bibliometric study was carried out in the Scopusdatabase. The word "biochar" was used in the search engine. The search was limited to articles and reviews published from 2009 to March 2020. The VOS viewer software was used to identify the main thematic axes and to glimpse the knowledge gaps that exist to date.Results: A total of 11,444 documents were identified. The trend of work on biochar is onthe rise. China and the United States are the countries with the most publications onbiochar. Jefferson Lehman and Stephen Josephs are the most cited authors on thesubject. Global research on biochar focuses on the mitigating effect of climate changeand the properties that this material has to improve the physicochemical properties ofthe soil. Research on biochar in Mexico is scarce. Study Limitations/Implications: Biochar is a new technology that is not fullyunderstood.Findings/Conclusions: Interest in biochar as a multifaceted solution to agricultural andenvironmental problems is growing at a rapid rate both domestically and internationally.

A data synthesis on the biochar properties and implications for air, soil, and water quality in Brazil

“…This scenario drives biochar studies as soil conditioner and other goals associated with healthy soils such as greenhouse gases emissions, effect on soil organisms, pesticide dynamics, PAHs contamination, fertilizer preparation, and growth media conditioner (Exhibit 1). Globally, the main biochar applications have been in environmental sciences and agriculture with emphasis as soil conditioner and water treatment (Abdeljaoued et al., 2020; Galindo‐Segura et al., 2021).…”

“…The world faces several global demands such as increase renewable energy, recycling of organic waste, reduction of environmental pollution, and materials with properties that can replace petroleum‐derived materials (Moustakas et al., 2020; Ouro‐Salim & Guarnieri, 2021). Biochar has been intensively researched as a candidate to partially supply these and other demands (Abdeljaoued et al., 2020; Galindo‐Segura et al., 2021). Biochar is the solid material obtained from thermochemical conversion of biomass in an anoxic environment (IBI 2012).…”
