Vegetative roofs are known for their environmental and economic benefits, such as providing habitats, mitigating the Urban Heat Island effect and lowering energy bills. This research will be done from a citizen science perspective to analyse the potential of this data collection method and its relevance for policymakers. A mixed-methods approach will be used by combining quantitative data from Netherlands Statistics (CBS) with qualitative data from observations of more than 75,000 addresses in The Hague collected from Google Maps. Coordinates and characteristics of the vegetative roofs will be analysed in Excel. Findings suggest a strong negative correlation between income and the number of people per vegetative roof, with r(4) = -.8981, p = .015075, which is consistent with previous research. Citizen science has been found to be a useful data collection method in this case, as it was able to identify more than four times as many vegetative roofs in the city as the data available from the municipality of The Hague. In conclusion, the collected data suggests a strong correlation between income and the number of vegetative roofs for neighbourhoods of The Hague and underscores the important role citizen science can play for (local) governments.Show less

The research aims to understand what actions can be undertaken by different stakeholders in order for green roof adoption to be accelerated and its many benefits to be yielded. A literature review was undertaken to examine barriers to green roof adoption as well as to explore the best practices in cities leading in green roofs: Chicago and Basel. Over the course of three structured interviews, the applicability of the best practices to Rotterdam was determined. The findings show that Rotterdam is limited financially and in terms of power over building demands. However, the municipality of Rotterdam, together with other important stakeholders involved with green roofs - such as installation companies or maintenance workers - can collaborate efficiently to raise awareness and reach a common goal: to increase the presence of (multifunctional) green roofs. This collaboration could exist in the form of quantitative research to publish facts and data about the positive impacts of green roofs in Rotterdam, or through qualitative interviews that aim to learn about the generally positive experiences of green roof owners.Show less
