Changing weather patterns challenge societies globally and at multiple levels related to amongst others health, the environment, disaster management and mitigation. There is a need for greater flexibility and resilience, which in turn can be enabled through a transition towards increased sustainability in governance and infrastructure. Urban rainwater harvesting (URWH) is a term used in this paper to collect various approaches to the sustainable handling of rainwater in cities, a practice becoming increasingly common in some areas of the world. Global experiences can be useful learning opportunities in the planning, implementation and maintenance of sustainable urban rainwater harvesting in future smart cities. The aim of this thesis was to synthesize the factors of success of previous projects, in order to develop a framework tailored to the evaluation of projects concerned with rainwater harvesting. The review spans over 18 projects of different scale and design. The findings of the study show that successful URWH projects are: (1) found as part of urban renewal schemes; (2) successfully implemented by involved actors with open mindsets and flexible and collaborative working approaches; (3) maintained based on plans determined from the onset of the project, developed together with local actors, in order to involve the community and strengthen social inclusion. The revised evaluative framework, which is proposed as a result of the review, indicates general trends of success among the reviewed cases. To be fully operational, the framework should be further developed with additional URWH projects and revised thereafter.

This thesis will explore the possible obstacles among Region Stockholm municipalities in promoting adolescents’ mental health and well-being through experimental governance. The thesis will examine the municipal and non-municipal points of view on specifically promoting adolescents’ mental health and well-being through experimental governance in the Swedish context with the use of urban sustainability transitions and transition management frameworks. The urban sustainability transitions will help us understand the role of cities in creating new modes of urban governing processes. In addition, the use of a transition management framework will help us to understand the importance of shifting from traditional management approaches by rather placing greater focus on innovative and design-oriented methods. This approach highlights the importance of learning by doing process rather than a reaching specific destination. In addition, I will use a qualitative research design that uses the methods of semi- structured interviews. The empirical findings are analysed with the help of thematic analysis through the theoretical frameworks and concepts. It has been demonstrated an observable slow- paced adoption of experimental governance, insufficient specific promotion of adolescents’ mental health and well-being, and distant relationship between experimental governance and promotion specifically adolescents’ mental health and well-being in the urban planning process.
