Water does not take municipality boundaries into account when it flows on land, and thus challenges related to climate change and flooding are often best solved when the municipalities work together. It was with this recognition that the Danish Board of Technology (DBT) met the seven municipalities of two Danish regions who share the water catchment of the stream Værebro. DBT along with three utility companies started the project Water across municipal boundaries (Danish: “Vandoplandsbaseret samarbejde på tværs af kommunegrænser”) which runs until spring of 2019. The goal is to encourage future collaboration between the municipalities in climate adaptation of the stream and catchment.
A common knowledge base is essential
The current project will result in a collection of all hydraulic data of the stream and all plans of current and expected land use of the catchment, which currently are placed in different municipalities, utility companies and other institutions. This will ensure a common knowledge base, which is essential for collaboration. Thus, the project can form the basis for future collaboration in the catchment with several obvious activities afterwards, e.g. creating a shared hydraulic model and involvement of stakeholders of the catchment.
Models and tools for climate adaptation across municipal borders
It is not only in the catchment of Værebro where planning and climate adaptation across municipal boundaries is best solved together. Experiences from this and similar projects will be collected in a ‘guideline’ by DBT and two partnering institutions on how to adapt to climate change in a water catchment consisting of several municipalities and/or regions. The guideline can be used by future collaborations across municipal boundaries and will include experiences of funding, conflicts of interest, data collection just to name a few.
