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.

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 risks of sustainable business strategies: Do sustainable business approaches change company risks?

PURPOSE: The aim of this research is to link sustainability strategies with risk management. DESIGN/METHOD: 33 unique cases were used for the data analysis. Using the cases, the researchers built a database to operationalise the theoretical framework. This database contains data on general characteristics of an organisation, strategic characteristics (mission, vision, value proposition, core values from the Balanced Score Card categories, strategic goals), strategy characteristics of the sustainability strategies, the 17 sustainability goals of the UN, risks (strategic, financial, operational) and control measures appropriate to the risks. RESULTS/FINDINGS: The first sub-question: Which risks at a strategic, financial, and operational level differ in organisations that pursue SDG 3 Good health and wellbeing, SDG 8 Decent work and economic growth and/or SDG 12 Responsible consumption and production, or do not pursue sustainability goals? It can be answered that sustainable values lead to different risks at strategic and financial levels, but not on an operational level. The second sub-question: Which risks on a strategic, financial, and operational level differ in organisations that pursue the sustainability strategy (Retain product ownership, Product life extension and/or Design for recycling) or do not pursue a sustainability strategy? It can be answered in a similar way as the first research question: that apparently sustainable strategies lead to different risks at strategic and financial levels, but not on an operational level. Operational risks were found but did not change in case of the sustainable strategy. ORIGINALITY/VALUE: Researchers have investigated whether pursuing the sustainability strategy (part 1) or contributing to the achievement of SDGs (part 2) by an organisation causes a change in strategic, financial and/or operational risks. Patterns were sought, not the magnitude of a change, because of the number of cases examined.

Research results of a new governance method in climate adaptation

Cities are becoming increasingly vulnerable to climate change and there is an urgent need to become more resilient. This research involves the development of the City Climate Scan methodology to measure, map, scan and assess different parameters that provide insight into the vulnerability of urban areas and neighborhoods. The research involved the development of a set of measurement tools that can be applied in different urban neighborhoods in a low-cost low-tech approach with teams of stakeholders and practitioners. The City Climate Scan method was tested in different cities around the globe with groups of young professionals and stakeholders in rapid urban appraisals.For the Rotterdam City Climate Scan (September 2017), the following challenges were selected: risk of flooding, heat stress, water quality (micro-pollutants and plastic waste) and air quality. The Rotterdam climate scan is evaluated with their triple helix partners (public, private and academic partners). The conclusion is that the City Climate Scan approach helps policy makers and practitioners to gather valuable data for decision makers in a rapid appraisal at the neighborhood and city level. The results of the City Climate Scan methodprovides insights, creates awareness and brings together stakeholders. The most valuable deliverable is the concrete and tangible results. The participatory approach brings residents and practitioners together and provides insight into local problems, while at the same time the method facilitates the collection of valuable data about the robustness of neighborhoods. As a result of this positive evaluation, the City Climate Scan will be up scaled to a number of cities in Europe and Asia in the upcoming months.

Climate risks for Dutch tour operators .

The perceived weather and climate change risks in Dutch agriculture

Purpose: This study analyses how weather shocks influence agricultural entrepreneurs’ risk perception and how they manage these risks. It explores what risks agricultural entrepreneurs perceive as important, and how they face climate change and related weather shock risks compared to the multiple risks of the enterprise. Design/methodology: This paper uses qualitative data from several sources: eight semi-structured interviews with experts in agriculture, three focus groups with experts and entrepreneurs, and 32 semi-structured interviews with agricultural entrepreneurs. Findings: not published yet Originality and value: This study contributes to the literature about risk management by small- and medium-sized agricultural enterprises: it studies factors that shape perceptions about weather shocks and about climate change and how these perceptions affect actions to manage related risks, and it identifies factors that motivate agricultural entrepreneurs to adapt to climate change and changing weather shock risks. Practical implications can lay the foundation for concrete actions and policies to improve the resilience and sustainability of the sector, by adjusting risk management strategies, collaboration, knowledge sharing, and climate adaptation policy support.
