A multi-level Thermal Comfort Assessment (TCA) to identify and mitigate heat stress risks in urban areas

The liveability of cities worldwide is under threat by the predicted increase in intensity and frequency of heatwaves and the absence of a clear spatial overview of where action to address this. Heat stress impairs vital urban functions (Böcker and Thorsson 2014), hits the local economy (Evers et al. 2020), and brings risks for citizens’ health (Ebi et al. 2021). The ongoing densification of cities may escalate the negative consequences of heat, while rising climate adaptation ambitions require new pathways to (re)design public places for a warmer climate. Currently, policy makers and urban planners rely on remote sensing and modelling to identify potential heat stress locations, but thermal comfort models alone fail to consider socio-environmental vulnerabilities and are often not applicable in different countries (Elnabawi and Hamza 2020).In the Cool Towns Interreg project, researchers collaborated with municipalities and regions to model urban heat stress in nine North-Western European cities, to find vulnerabilities and to measure on the ground (see Spanjar et al. 2020 for methodology) the thermal comfort of residents and the effectiveness of implemented nature-based solutions. Using the Physiological Equivalent Temperature (PET) index, several meteorological scenarios were developed to show the urban areas under threat. The PET maps are complemented by heat vulnerability maps showing key social and environmental indicators. Coupled with local urban planning agendas, the maps allowed partner cities to prioritize neighbourhoods for further investigation. To this end, community amenities and slow traffic routes were mapped on top of the PET maps to identify potential focus areas.A comparative analysis of the collated maps indicates certain spatial typologies, where vital urban activities are often influenced by heat stress, such as shopping areas, mobility hubs, principal bicycle and pedestrian routes. This project has resulted in the development of a multi-level Thermal Comfort Assessment (TCA), highlighting locations where vulnerable user groups are exposed to high temperatures. Standardized for European cities, it is a powerful tool for policy makers and urban planners to strategically identify heat stress risks and prioritize locations for adapting to a changing climate using the appropriate nature-based solutions.

Do experts agree when assessing risks?

Risk matrices have been widely used in the industry under the notion that risk is a product of likelihood by severity of the hazard or safety case under consideration. When reliable raw data are not available to feed mathematical models, experts are asked to state their estimations. This paper presents two studies conducted in a large European airline and partially regarded the weighting of 14 experienced pilots’ judgment though software, and the calculation of agreement amongst 10 accident investigators when asked to assess the worst outcome, most credible outcome and risk level for 12 real events. According to the results, only 4 out of the 14 pilots could be reliably used as experts, and low to moderate agreement amongst the accident investigators was observed.

Transition pathways, risks, and uncertainties

The 2018 IPCC Special Report on Global Warming of 1.5 °C once again highlighted (and with increased urgency) the benefits of immediate, extreme decarbonisation efforts in order to minimise the negative impacts of climate change. Achieving such demanding global targets requires concerted national, subnational, and local efforts. In combination, these efforts result in transition pathways. Implementation of the technologies and policies at the heart of such pathways is often considered as inherently positive, thus the immediate risks associated with the pathway are the barriers faced on implementation. However, successful implementation of a climate change mitigation policy may also have potentially negative consequences. On either side a host of more abstract uncertainties increase the difficultly of decision making. In this chapter, we provide a synthesis of eleven low-carbon transition pathways from across the globe and explore the risks and uncertainties associated with them. We structure our discussion around three nested dimensions present in all pathways: technological innovations implemented in a local context; policy mixes promoting these technologies; and society, where social-economic priorities may lead individuals and communities to support or oppose the low-carbon pathway. Across these themes, we also explore the meaning of scale and stakeholders’ perceptions of time in low-carbon pathways. Our discussion reflects the complexity associated with assessing risks in contested settings. While many of these risks are context specific and reflect a broad range of stakeholder perspectives, common risks are found across the case studies, regardless of the local context, the technology promoted, and the policy mix implemented.

The embracement of risks

This essay explores the notion of resilience by providing a theoretical context and subsequently linking it to the management of safety and security. The distinct worlds of international security, industrial safety and public security have distinct risks as well as distinct ‘core purposes and integrities’ as understood by resilience scholars. In dealing with risks one could argue there are three broad approaches: cost-benefit analysis, precaution and resilience. In order to distinguish the more recent approach of resilience, the idea of adaptation will be contrasted to mitigation. First, a general outline is provided of what resilience implies as a way to survive and thrive in the face of adversity. After that, a translation of resilience for the management of safety and security is described. LinkedIn: https://www.linkedin.com/in/juul-gooren-phd-cpp-a1180622/
