Research Methodologies in Brownfield Redevelopment Studies: A Meta-Methodology Systematic Review

Most developed countries welcome the redevelopment of brownfield sites and consider it an effective tool for urban policy. However, its adoption can be challenging initially, particularly in developing countries where these challenges are significantly greater. This research aims to answer the question, “How are research methodologies applied in the field of brownfield redevelopment studies?” Following the PRISMA 2020 guidelines, rel- evant studies were identified through searches in Web of Science, ScienceDirect, Google Scholar, and Semantic Scholar. This study utilizes a meta-methodological approach to analyze and compare the methodological characteristics of brownfield redevelopment studies. After applying the predefined eligibility criteria, which included English-language peer-reviewed articles between 2018 and 2023 and articles that are directly relevant to brownfield redevelopment, 20 articles were selected for detailed examination. Based on the thematic classification of the research, the studies can be categorized into four groups: brownfield redevelopment and community participation, brownfield redevelopment and urban planning, brownfield redevelopment and environmental sustainability, and brown- field redevelopment and technology. The majority of the research relates to brownfield redevelopment and environmental sustainability. This review suggests that research in brownfield redevelopment has been dominated by quantitative research, and there is a need for more comparative, theoretically oriented, and methodologically integrated research.
