Trends in urban edible landscapes: a comprehensive bibliometric analysis

Abstract

In response to the dual challenges of urbanization and population growth, urban edible landscapes have emerged as innovative green infrastructure with the potential to address ecological, social, economic, and food security issues. This study systematically analyzes 3,089 publications from 2000 to 2024, sourced from the Web of Science database, using keywords such as ‘Edible Landscapes,’ ‘Edible Garden,’ ‘Rooftop Garden,’ ‘Community Garden,’ and ‘Productive Landscape.’ This study adopts bibliometric and visualization tools, such as CiteSpace and R, to systematically sort out and visualize the research hotspots, knowledge structure, emerging trends, and the evolution of this field. The analysis begins with a co-occurrence network of keywords, identifying core topics and evolving research trends. Cluster analysis further delves into various research themes, elucidating the field’s main directions and focal points. The paper highlights the multifaceted impacts of edible landscapes on urban ecosystems and residents’ well-being, emphasizing their critical role in promoting urban sustainability. Additionally, it outlines strategic recommendations for policymakers and stakeholders to enhance the implementation and expansion of urban edible landscapes in alignment with sustainable development goals. This research provides comprehensive insights into the historical evolution, status, and future trends of urban edible landscape studies, offering valuable guidance for policy development and practical innovation in both academic and real-world contexts.
