Target audience
Urban designers, architects, and landscape architects. Government policymakers at national, regional, and local level.
The problem
Major and accelerated changes in waterfronts (bearing little resemblance with rivers’ once natural state) have led to greater water overflows, pollution, and the destruction of ecosystems, exacerbated in the context of rapid urbanisation and climate change. Interfering infrastructural works were sometimes followed by social conflicts or protests, as the social connectivity along riverfronts was temporarily or permanently altered. Such a challenging case is Liffey Boardwalk disconnected from the river and facing anti-social behaviours.
What we did and why
Interventions on riverfronts require close consideration of contextual ecological and social aspects. We adopted a research-by-design process to discuss nature-inspired urban design strategies in an Irish context.
• We conducted a desk study of academic literature and urban policies to establish the suitability of various methods for the site characteristics;
• We performed site analyses (site observations, footfall counting, photographic documentation) for an in-depth understanding of the existing conditions;
• We developed urban design scenarios to envision potential approaches, for which public feedback was sought.
Our study’s contribution
This study provides new perspectives on how riverfronts could be transformed into more natural and vibrant social spaces, bridging the gap between academia and urban design practice. While documenting multiple blue-green infrastructure or water-sensitive urban design approaches and techniques, the site conditions restricted their applicability to a handful. For the Liffey Boardwalk, the biophilic design emerged as the most pliable strategy. The entire research-by-design process is presented and illustrated in urban design scenarios.
Impacts for city policy and practice
For the incorporation of nature-based strategies in complex and problematic real contexts, more effort and further innovative approaches are needed to link rigorous academic research (that requires more time and resources) with design practice (usually having a limited timeframe of delivery). This would, however, eliminate some of the obstacles in implementation and uptake. Involving citizens in co-designs and co-creation could ensure public interest and acceptance, or lead to further refinements of scenarios.

There is limited evaluation of whether green space interventions lead to more people using these spaces. This is partly due to the difficulty of collecting data on visits to green spaces. Mobile phone data may offer one solution, but are rarely made available to researchers. As such, there is less examination of whether these data are valuable. We accessed small area anonymised mobile phone GPS data for Liverpool (2021-2022). Using a case study of wildflower planting, we identified green spaces where wildflowers were planted. A synthetic control was then constructed to identify similar green spaces where planting did not take place. We then compared the number of visits post-intervention between the intervention and control green sites. Our paper also gives an empirical and methodological evaluation of the strengths and weaknesses of using mobile phone data, which can inform others on how to best use them.
With so many different forms of guidance available for incorporating health into planning, our study evaluated what makes a healthy planning framework successful.
This work unveils the heterogeneous preferences of different hospital users for green infrastructure improvements that could improve their health and wellbeing. Moreover, it shows that distinct motivations determine their demand for spending time outdoors and their willingness to pay for these improvements.
