This paper delivers actionable recommendations towards building a rationale for activating and promoting Underground Built Heritage (UBH) based on the nexus heritage, territory and society, and making use of existing literature and findings from five international cases. The research was conducted in the framework of the working group on Planning Approaches of the COST Action Underground4value. The analysis of the cases aims to provide guidelines for this working group and to benchmark good practices in activating UBH. It highlights the importance of community-led initiatives, leadership and dialogue and power sharing between the local/regional authorities and communities aiming for better understanding of the potential of UBH. The successes and/or failures of the five cases emphasise the importance of knowledge and experience in participatory approaches. Success was verified, when effectiveness and democratic principles were combined in the planning process, and local history is integrated with citizen science, co-creation and placemaking. The analysed approaches stimulate a new hybrid layer for activating UBH, provide mechanisms of mediation between people and heritage, and contribute to cultural and social dimensions of sustainability. This is a highly challenging endeavour, as it seeks to support and advance a sound understanding of UBH as a sustainable resource, backed by strategic stakeholder dialogue and contextual knowledge. Such effort requires a dynamic understanding of UBH values, knowledge, abilities and skills, towards creating more effective coalitions of “actors” within localities, by developing structures, which encourage long term collaborative relationships.

The new information and communications technologies are expanding human connectivity, reconfiguring urban spatialities and generating a kind of social space that spans real and virtual, personal and impersonal, private and public. As a result, the space and time boundaries become blurred, giving rise to novel needs for, and practices of, public space usage. However, the ways in which these new practices affect public space engagement and public life in general, remain yet unclear. In addition, variations might exist due to differences in local culture and conditions, or due to specific lifestyles and behaviours favouring isolation and privatism or, at best, interaction only with close friends and kin. The above issues become even more critical for young people, who born in a digital era are able to handle new technologies with utmost ease. This chapter sheds light on the related perceptions and practices of adolescents. Structured interviews were applied to eight teenagers living in Hannover (Germany), Lisbon (Portugal), Tel Aviv (Israel) and Volos (Greece) to gather focused, qualitative and textual data. It examines how young people of distinct sociocultural contexts perceive and use both public spaces and digital technologies. This enables to identify emergent logics, needs and patterns of socialization and public space engagement placing specific emphasis on the role information technologies can play in them.

This article discusses collaborative ethnography as a meaningful source for spatial research, in particular, for participatory methodologies in urban planning and placemaking processes. It investigates the experiences with co-creation and co-research in different research projects to gain insight into the performance of collaborative ethnography as a technique to explore and enrich local knowledge. To better understand the possible causal relationships between the experience gained in the projects and the learnt lessons, we also identify recommendations for improving research methodologies to be applied in placemaking. This article concludes that collaborative ethnography is an effective tool for adding value to spatial co-research and co-creation processes. It opens opportunities for the co-production of space, ideas and knowledge, contributing at the same time to better informed decision-making. It also helps improve ideas and gather insights into the spatial needs of focus groups.

Partindo do pressuposto que a objectividade e visibilidade do espaço é possível através do estudo do "lugar", abordo algumas perspectivas de âmbito teórico e empírico que, no decurso da investigação em contextos urbanos, têm-me permitido reflectir sobre os processos de manutenção e transformação socio-espaciais. Utilizo como parâmetro balizador desta reflexão a ideia de "remodelação", por entender que esta permite entender as dinâmicas socio-espaciais como processos de (re)criação ou invenção constante dos espaços-habitat, das formas de habitar e das formas de pensar o habitat.
