This paper presents a structured methodological approach to constructing thematic good practices inventories for urban transformation, based on two guidebooks developed by the Izmir Planning Agency in coordination with the Turkish Healthy Cities Association and Izmir Metropolitan Municipality. The series operationalizes the Sustainable Development Goals (SDGs), the One Health framework, and the WHO Healthy Cities Phase VII themes (6Ps), addressing contemporary urban challenges through an equity-focused lens. The first volume, Good Practices for the Healthy Cities of the Future, centers on projects that integrate environmental, human, and animal health, while the second, Good Practices for Disability-Inclusive Cities of the Future, extends the framework to include rights-based urban design and inclusive governance. Across both volumes, a multi-phase evaluation process was applied, incorporating SDG alignment, replicability, digital visibility, and spatial scale. The findings demonstrate how good practices, when systematically categorized, support comparative learning and local policy adaptation. Key insights highlight the importance of thematic breadth, the underrepresentation of certain dimensions such as animal health, and challenges in scaling successful pilots due to institutional, regulatory, or funding barriers. Future volumes will expand on these lessons, including a forthcoming guide on elderly health. Izmir Metropolitan Municipality also plans to implement local healthy city solutions based on these good practices, aligning global insights with its urban development strategies. Overall, the Good Practices series contributes to an emerging urban planning culture in which health, inclusivity, and sustainability are jointly pursued as central public priorities.
