Mainstreaming nature-based solutions through five forms of scaling: Case of the Kiiminkijoki River basin, Finland.

Nature-based solutions (NBS) are considered as means to tackle climate change and biodiversity loss while simultaneously enhancing human well-being. Yet, it is still poorly understood how NBS could be mainstreamed. We address this gap by proposing a framework on NBS and employing it in Finland's Kiiminkijoki River basin through participatory workshops and a questionnaire.
