Abstract
Challenges associated with growing urban areas and the interaction of economic factors related to water management and climate change, lead to a need for innovation in the sector. One of the approaches to address the issues of sustainable stormwater management and resilience against flooding in urban areas is nature-based solutions (NBS). NBS intends to protect, sustainably manage, and restore natural and modified ecosystems by including innovative solutions for water management. This master’s thesis aims to investigate the current practice of documentation of NBS in Norway; what type of data stakeholders need NBS, and desired minimum requirements for registration of NBS. This was done by collecting information from literature and interviews with Norwegian informants with knowledge of NBS. Processing of the interviews’ data was done with NVivo, while illustration of the results was done in MindManager. Results showed that there is not adequate documentation of NBS in Norway today due to a lack of sufficient knowledge and a system for this. Requirements of a system for registration of information and other data from literature were included in a comprehensive interactive map, where data were linked to different user-profiles and categorised within types of decisions and levels for approach. From the interactive maps, a list of minimum requirements for registration of new NBS was developed as a suggestion for data to include in a digital portal for documentation of NBS.
