“…Within focus group discussions and also throughout key literature we found that beyond the radical transformation of social, technical and technical systems, integrated urban water management is often underpinned by pragmatic economic considerations (ECONF) (Alves et al, 2018). BGI has been shown to positively influence property values (Hoover et al, 2020), generate greater tourism amenity (Cook et al, 2019;Whiteoak, 2019), and promote the circular economy (Langergraber et al, 2020).…”

“…Stormwater water management frameworks, to protect urban areas from flooding and provide waterway and pollution protections (Whiteoak, 2019;Renouf et al, 2020), also enable the provision of alternative water supplies. The physical infrastructure required for these frameworks, e.g., blue-green infrastructure (BGI), can also provide cooling benefits (Demuzere et al, 2014b;Jamei and Tapper, 2019;Probst et al, 2022).…”

The process of urbanisation has increased public health risks due to urban heat, risks that will be further exacerbated in future decades by climate change. However, the growing adoption of integrated water management (IWM) practices (coordinated stormwater management of water, land, and resources) provides an opportunity to support urban heat amelioration through water supply provision and irrigated and vegetated infrastructure that can provide cooling benefits. This study examines the thermal impacts of future implementations of IWM for nine Australian cities based on a review of Government policy documents in the present and over two future time frames (2030 and 2050) under different greenhouse gas emission scenarios (SSPs 1.2-6, 3.7-0 and 5.8-5). Statistical analysis of the future climate data using historical data shows that future warming is nuanced, with changes variable in both time and place, and with extremes becoming more pronounced in future. We have developed a unique approach to morph the future climate projections onto historical data (derived from the ERA5 Reanalysis product) for the 2010-2020 period. Additionally, we use locally appropriate Local Climate Zones (LCZs) for Australian cities, resulting from a holistic and global approach that is widely adopted by the urban climate modelling community. We developed scenarios for business-as-usual as well as implementation of moderate and high levels of IWM across each of the Australian LCZs and modelled them using TARGET (The Air temperature Response to Green infrastructure Evaluation Tool). Results generated at the LCZ level are aggregated to Australian statistical areas (SA4, the largest sub-city area) and city-wide levels. The thermal impacts associated with the various degrees of IWM were marked and geographically differentiated, depending on the climatic characteristics of the various cities. For the current climate, high IWM intervention provided reductions in annual mean daily maximum temperature ranging from -0.77°C in Darwin, up to -1.86°C in Perth. Generally, the drier southern cities of Sydney, Canberra, Albury, Melbourne, Adelaide, and Perth produced the greatest thermal response to implementation of IWM and the more tropical cities with higher rainfalls the least response. For some southern cities cooling was > -3.0°C at the time of maximum summer temperatures. Interestingly high levels of IWM in winter produced modest warming of minimum overnight temperatures, especially for the cooler southern cities. The cooling benefits of IWM were seen across all future climate scenarios and are a real opportunity to offset-projected temperature increases resulting from climate change.

“…In their study, Whiteoak and Saigar (2019) offer an economic framework for estimating the benefits of greening and water management projects. They use a standard cost-benefit analysis approach to compare the costs of these projects with their potential benefits, such as water savings, health benefits, recreation value, and electricity savings.…”

Bridging the Implementation Gap: A Holistic Approach to Urban Climate Governance

As urbanization continues to grow, urban climate issues such as urban heat island effect have emerged. The "implementation gap" refers to the significant difference between the number of effective methods available to tackle these problems and the few cities where they have been implemented to some extent. Contrary to most literature, our hypothesis is that this gap is due to the research not being structured in a way that enables effective decision-making. Therefore, we propose an expanded concept of urban climate maps that includes all scales of the city and stages of urban development as a solution.Four case studies at different scales are briefly analyzed to reinforce this point and provide a clearer idea of the immense opportunity for cities to develop these climate maps.
