Evaluating the scientific contributions of biogas technology on rural development through scientometric analysis

Abstract The strength of rural area in pioneering technologies encountering the current challenges of biogas research has been less addressed. Scientometric analysis has been carried out to understand research trends, perspectives and promising future prospects of biogas technology in rural development. 1427 publications have been retrieved from scientific databases and analysed for major contribution of international collaborative partners, current research hotspots and subject areas to assess the evolution of biogas technology. Scientific publications on biogas grew rapidly from last decade wherein China has the highest research publications of 324 with 23.08% significant contribution. Keywords clustering analysis showed pretreatment strategies, influence of substrate mediators and its microbial interaction for process upgradation were the promising main research hotspots. The subject categories, “Energy and Fuels” is more popularized whereas “Economics” needs more attention. This study gives and insight on scientific advances and potential research gaps of biogas technology for rural development at global level.
