The historical canal that was disconnected by a road in the 1970s is currently being restored by the municipality, creating a lively atmosphere allowing for water recreation, a boulevard and green spaces (ref. 1). A small element of this restoration is the addition of green elements by a citizen group, which entails improving ecological, aesthetic and historical quality of the canal by implementing eco-friendly riverbanks, green connecting zones and floating vegetation islands (ref. 3,9,11,12).

Project objectives

The main goals were improving water quality, improving aesthetic and cultural/historical value and improving environmental quality within the canals of Utrecht (ref. 11) Additional goals were: Biodiversity: by providing habitat and breeding grounds for species and creating green corridors (ref. 4,10,12) Improving local climate (temperature and air quality) (ref. 9) Inclusive governance: the community group mobilizes volunteers for maintenance of the vegetation (ref. 3,12)

Implementation activities

Green corridors: connecting green zones between different parts along the canal (ref. 8) Eco-friendly river banks with diverse vegetation, flower-rich embankments and exit points for animals (ref. 9,11,12) Water plants and 'floating vegetation inslands' that improved water quality and provided habitat and breeding grounds (ref. 12) Ecological art project by Birthe Leemeijer that was being created (ref. 12) Mussel crates that are used as pilot measurement by Ecologisch Adviesbureau Waardenburg (research and consultancy bureau) that provided insight into the ecological value of mussels (ref. 10)

Participatory approaches/ community involvement

  • Co-planning
  • Consultation (e.g. workshop, surveys)
  • Joint implementation (e.g. tree planting)
  • Co-management/Joint management
  • Citizen oversight (e.g. boards, advisory)
  • Citizen monitoring and review

Details on the roles of the organisations involved in the project

Restoration of the historical canals is initiated and being implemented by the muncipality of Utrecht. The green elements are initiated by citizens who formed the community group 'Initiatiefgroup Vergroening Singel' (Initiative Group Greening the Canal) (ref. 7,9,12). Their plan fitted into one of the 'wijkwaterplannen' (Neighborhood Water Plans) of the municipality of Utrecht and therefore the municipality and the Hoogheemraadschap Stichtse Rijnlanden (local water body) became involved and financially support the project (ref. 12). The design is performed by members of the community group, the municipality and the water body supported in implementing the plan and the targets are monitored by the community group (ref. 12). The community group is responsible for citizen volunteers that do maintenance activities for the green measurements [12]. The consultancy company 'Ecologisch Adviesbureau Waardenburg' is involved because they research the effect of the mussel crates on water quality and ecology (ref. 11).

Project implemented in response to ...

... an EU policy or strategy? Unknown
... a national policy or strategy? Unknown
... a local policy or strategy? Yes (The project was initiated as a response to the restoration of the historical canal of Utrecht which has been ongoing since 2010 and will be finished in 2020. During the 1970s, the canals was disconnected to improve mobility in the city, but the municipality of Utrecht is currently restoring and 'reconnecting' the canal taking into account water transport ability, green space, history, recreation and habitat for species (ref. 1, 2). However, citizens were unsatisfied with the steep concrete river banks that were created in 2012 as part of the restoration of the canal by the municipality which does not allow for vegetation and animals to enter or leave the water. Also, it did not fit the historical quality of a landscape park like the Zocherpark. This led to the formation of the Citizen Initiative Group and motivated them to take the initiative (ref. 14).)
