Green Equity in Urban Sustainability: A Scientometric Analysis of Research Trends from 1992 to 2021

Abstract

This study addresses the critical intersection of climate change, rapid urbanization, and the necessity for sustainable governance models that prioritize environmental health and equitable access to environmental benefits. Focusing on the increasingly relevant concept of green equity, we conducted a scientometric analysis based on a systematic literature review to trace its research evolution from 1992 to 2021. Utilizing the open-source R-tool Biblioshiny, we analyzed academic publications to discern major research themes and their correlation with significant milestones in sustainable development. Our methodology enabled the identification of key research areas and the evolution of thematic lines within the green equity discourse. Notably, we observed a surge in scientific interest and diversity in topics associated with green equity, propelled by international frameworks like the Sustainable Development Goals (SDGs). The expanding body of research encompasses a wide range of issues, including climate change, accessibility to green spaces, ecosystem services, green infrastructure, and socioeconomic factors. Additionally, our study highlights the dynamic patterns in global collaborative networks contributing to this field. The findings underscore the growing prominence of green equity in academic discourse, reflecting its critical role in shaping sustainable urban futures.
