This paper examines the role of social research and communication methodologies in fostering substantive democratic participation and policy co-production within the context of urban regeneration initiatives anchored in the United Nations Sustainable Development Goals. This research critically analyzes the “becoming public” of sociology and social research in participatory design processes related to traditional urban planning instruments at the local scale (Regulatory Plans) in the Italian context, specifically through the case study of the Municipality of Appignano. It questions the role of sociology in activating a competent public sphere and promoting deliberative democracy at urban and territorial design levels and whether we can identify the traits of public sociology in facilitating the different stages of these processes. This paper details a participatory process in Appignano that sought to innovate urban regeneration within complex legislative frameworks, emphasizing community engagement and interdisciplinary approaches. The findings reveal a community actively participating in the regeneration process, demonstrating a high level of agreement on various urban development strategies aimed at sustainability. This study underscores the capacity of public sociology to facilitate public debate and democratic dialogue and suggests that such participatory approaches can significantly contribute to sustainable and resilient urban development, highlighting the potential of sociology as a moral and political force in urban planning.

This article examines the role of urban design in integrating biodiversity preservation with the enhancement of environmental and human health and quality of life in urban and peri-urban areas. Building on three complementary perspectives—urban design, the Healthy Habits framework, and socio-ecological networks—the review seeks to bridge short- to medium-term actions for improving the quality of life with long-term strategies for biodiversity preservation. While partial connections between these domains exist, they remain fragmented, underscoring the need for a holistic and transdisciplinary approach to urban socio-ecological health. The study employs a two-stage methodology, combining a scoping review to map existing evidence with a qualitative thematic review across SCOPUS-indexed research, European and international policy frameworks, and practical applications. The One Health paradigm is used as the principal integrative tool to link urban design, the Healthy Habits framework, and the socio-ecological networks. The topics of European environmental policies, evolutionary pillars, and social cohesion are incorporated to strengthen the interrelations between environmental and societal health and well-being. The findings highlight the importance of a holistic approach, behavioural insights, urban nudges, and participation, which can become key elements in fostering social cohesion, ecological resilience, and overall health. The research concludes that health-oriented urban design must go beyond traditional planning paradigms and tools, adopting adaptive, relational, and transdisciplinary approaches to address the challenges posed by contemporary times.
