A brownfield regeneration in urban renewal contexts visual analysis: research hotspots, trends, and global challenges

Brownfield regeneration is considered a crucial aspect of urban revitalisation, offering indispensable opportunities for socially, economically, and ecologically sustainable development and land resource reuse in the framework of urban structural transformation. Nevertheless, only a limited number of studies have sought to offer a comprehensive and quantitative study of this subject matter. As a result, this study has conducted a systematic, global review of brownfield regeneration in the context of urban renewal research. By means of quantitative analysis and visual knowledge mapping based on CiteSpace and VOSViewer tools, the research explains the network of theoretical collaboration among different countries, highlights research phasing, focal points, and trends, and critically discusses the global challenges integrated with social, ecological, economic, and political sustainability goals. This study offers researchers and practitioners alike a systematic and visual analysis of the principal research themes and trends in brownfield regeneration and global urban renewal.
