Students, Researchers, stakeholders from the private and public sectors are very welcome to join the HYBGEN Collaborative Workshop to discuss new living and working strategies young adults (20-35 years old) of Oslo region are adopting to face current challenges (housing affordability, increasing flexible work, new mobility and commuting patterns) and how such strategies intersect with urban green care. The collaborative workshop will be moderated and facilitated by Mina Di Marino, Associate Professor, Department of Urban and Regional Planning, NMBU, and Maria Assunção Gato, Researcher at DINÂMIA’CET-Iscte, Instituto Universitário de Lisboa. The workshop is part of the HybGen project and aims to collect answers to these questions from young adults and other actors and stakeholders in the urban regions of Lisbon and Oslo, in order to identify challenges, solutions and strategies that can better meet their expectations. Young adults (20-35 years old) are the most prone to emerging trends and lifestyles that can be characterized as hybrid, by embracing co-housing strategies and increase in green and shared mobility, flexible and shared workplaces, and diverse spatial arrangements, as well as various socio-cultural influences, coupled with digital dependency. In addition to some difficulties in affording a house and having a good job and salary, young adults are also being asked to devote greater attention to the ecological transition and urban green care. Despite ongoing discussions surrounding hybridization, there remains uncertainty about how this concept manifests in the lifestyles adopted by young adults who serve as key protagonists in these trends. Additionally, it is unclear how these lifestyles intersect with ecological transition and sustainability, especially in distinct urban regions such as Lisbon and Oslo.
