Green Roof Deal
A short description of the NBS project
Operatie Steenbreek (literally: operation stone break. Dutch wordplay) is a foundation that organizes awareness raising campaigns and offers assitence with regards to greening private gardens. Many gardens and streets in the Netherlands are covered with tiles that cannot absorp the rainwater from (increased) heavy rainfall. The idea behind the initiative is to encourage citizens to remove the tiles and stones from their gardens/ backyards and replace it with grass, plants and trees for better drainage and to inrease the 1. Volunteers working for the organization offer advice to citizens, there is an app that offers advice and a platform for citizens to exchange plants with neighbours. Citizens can furthermore measure the performance of their own green garden and discuss the results in focus groups
as a kind of citizen science. The initiative calls this form of science the BIMBY (1 in my back yard) method following Beumer and Martens (Beumer & Martens, 2014; Beumer, 2014).
Operatie Steenbreek offers help to municipalities in setting up an Operatie Steenbreek initiative in their own town or city and adapt it to the local circumstances (they can pick and choose from the methodology). The national platform provides opportunities for municipalities to share information, experiences and knowledge.
The objectives of the intervention are:
-to raise awareness and offers assitence with regards to greening private gardens.
-to decrease the amount of gardens and backyards that are covered with tiles to absorp the rainwater from (increased) heavy rainfall and to increase the 1
-to encourage citizens to remove the tiles and stones from their gardens/ backyards and replace it with grass, plants and trees for better drainage
-to let Citizens measure the performance of their own green garden and discuss the results in focus groups as a kind of citizen science (BIMBY: 1 in my back yard method following Beumer & Martens, 2014; Beumer, 2014)
-to dissemenate the methodology amongst as many Dutch municipalities as possible

Description of the NBS
NBS Impacts scale
Urban density/ Soil consumption
Combined with other(s) environmental friendly solution(s)?
Project manager (leader and main partners): entities names, and know-how involved
Leader: Alterra/WUR and Groningen University
Main partners: Municipalities
Who (else) was involved in the project ? (Inhabitants, local association, etc.)
Municipalities: can implement the methodology and use the tools that have been developed
Citizens: as volunteers in the local projects and renovators of their garden and backyards
Environmental, ecologist organisations: as volunteers to offer advice and assistence
More detail on the process and the role of the different stakeholders (How did it happen?)
Three kinds of "other" actors were involved:
-Environmental, ecologist organisations: Groei & Bloei, Entante Florale, De vitale groene stad, Klimaatverbond, IVN, Duurzaam Den Haag, Volgelbescherming (bird protection), KNNV (biologists).
-Knowledge institutes: Maastricht University, Larenstein
-Strategic partner: DonkerGroen (garden design)
Citizens participe as volunteers to green their gardens. Environmental, ecologist organisations offer advice and assistence. Knowledge institutes participate to the citizens research project.
OPTIONAL Considering the actual impacts, who are the primary beneficiaries of the project.
Citizens and municipalities
It’s a (loosely organised) networked organisation that creates conditions for citizens to green their gardens
Global Estimated cost of the project
Description of the financing mechanism
The project is financed by municipalities that adopt the methodology. Furthermore, volunteers work for the organization and investements for greening the gardens are done by private citizens. Note that most of the measures are on a low budget basis
Adopt a stewardship role
See financial mechanism
Expected time for the NBS to be fully effective after its implementation
medium (between 2 to 5 years)
Expected life time of the intervention
more than 30
Already feedbacks on the project? In case, the project has already been adapted to new requisites, please explain the modifications brought
More partners involved. Replicated in many other municipalities in the Netherlands
Success and limiting factors
Awareness raising campaign aims to stimulate private citizens to green their gardens
Tools and such are meant to remove knowledge barrier for greening gardens
There are many partners involved. Hence there are issues with ownership (organisational aspect). Furthermore, the project depends on citizens who volunteer to green their garden. There are no other incentives rather than knowledge/ awareness
What makes this project a pioneer?
Brief description of the innovativeness
Low budget project
Sharing economy: app to exchange plants
Has the project received a prize, an award?
Has the project received a media coverage? (in reviews, in press, etc.)
