Resumen
Gentrification is a controversial term that refers to certain changes in neighbourhoods that result in the economic and social transformation of a low-income area into one of higher value, moving or pushing out the old population and businesses. The purpose of this paper is to highlight a new branch of research in the field of environmental studies. It presents a bibliometric analysis of the gentrification process, scanning the scientific articles published in journals since 1979, from different knowledge areas and analysing the impact factors and the evolution of the term itself. The review of scientific journals uses the Web of Science and Scopus databases for analysing the evolution of papers, the impact factors and references related to this concept. The results show that the literature related to gentrification is increasing at a very high rate, particularly in the fields of environmental science. Since 1987, the number of scientific papers in environmental studies that have focused on this topic have increased at an annual rate of 60.4%, making it a promising subject for researchers. Thus, the article represents a contribution to identify the main trends in gentrification research and environment and, from there, propose future research initiatives.
