Perceptions of heatwave risks to health: interview-based study of older people in London and Norwich, UK

BACKGROUND Most projections of climate change suggest an increased frequency of heatwaves in England over coming decades; older people are at particular risk. This could result in substantial mortality and morbidity. OBJECTIVE To determine elderly peoples knowledge and perceptions of heat-related risks to health, and of protective behaviours. METHODS Semi-structured interviews: 73 men and women, 72-94 years, living in their own homes in London and Norwich, UK. RESULTS Few respondents considered themselves either old or at risk from the effects of heat, even though many had some form of relevant chronic illness; they did recognize that some medical conditions might increase risks in others. Most reported that they had taken appropriate steps to reduce the effects of heat. Some respondents considered it appropriate for the government to take responsibility for protecting vulnerable people, but many thought state intervention was unnecessary, intrusive and unlikely to be effective. Respondents were more positive about the value of appropriately disseminated advice and solutions by communities themselves. CONCLUSION The Heatwave Plan should consider giving greater emphasis to a population-based information strategy, using innovative information dissemination methods to increase awareness of vulnerability to heat among the elderly and to ensure clarity about behaviour modification measures.

Adaptation opportunities, constraints, and limits

Since the IPCCs Fourth Assessment Report (AR4), demand for knowledge regarding the planning and implementation of adaptation as a strategy for climate risk management has increased significantly (Preston et al., 2011a; Park et al., 2012). This chapter assesses recent literature on the opportunities that create enabling conditions for adaptation as well as the ancillary benefits that may arise from adaptive responses. It also assesses the literature on biophysical and socioeconomic constraints on adaptation and the potential for such constraints to pose limits to adaptation. Given the available evidence of observed and anticipated limits to adaptation, the chapter also discusses the ethical implications of adaptation limits and the literature on system transformational adaptation as a response to adaptation limits. To facilitate this assessment, this chapter provides an explicit framework for conceptualizing opportunities, constraints, and limits (Section 16.2). In this framework, the core concepts including definitions of adaptation, vulnerability, and adaptive capacity are consistent with those used previously in the AR4 (Adger et al., 2007). However, the material in this chapter should be considered in conjunction with that of complementary WGII AR5 chapters. These include Chapter 14 (Adaptation Needs and Options), Chapter 15 (Adaptation Planning and Implementation), and Chapter 17 (Economics of Adaptation). Material from other WGII AR5 chapters is also relevant to informing adaptation opportunities, constraints, and limits, particularly Chapter 2 (Foundations for Decision Making) and Chapter 19 (Emergent Risks and Key Vulnerabilities). This chapter also synthesizes relevant material from each of the sectoral and regional chapters (Section 16.5). To enhance its policy relevance, this chapter takes as its entry point the perspective of actors as they consider adaptation response strategies over near, medium, and longer terms (Eisenack and Stecker, 2012; Dow et al., 2013a,b). Actors may be individuals, communities, organizations, corporations, non-governmental organizations (NGOs), governmental agencies, or other entities responding to real or perceived climate-related stresses or opportunities as they pursue their objectives (Patt and Schroter, 2008; Blennow and Persson, 2009; Frank et al., 2011).

Climate Change Adaptation as a Social Process

Research on the impacts of climate change suggests that developed countries are not immune to the effects of a changing climate. The assumption that because of their high adaptive capacity, developed countries will adapt effectively is beginning to be dispelled by empirical evidence. While advancements in projections have facilitated a move from the study of impacts to concrete adaptation strategies, research that focuses on the social process of adaptation has been relatively neglected. Yet, when viewed as a social process, the psychological, social, and cultural aspects of adaptation are exposed, which brings into focus the effects that values and power dimensions have on actual adjustments and their outcomes for adaptation. This chapter demonstrates that some of the critical barriers to adaptation in developed countries arise from perceptions and values. It argues that these barriers are hindering adaptation now and will continue to do so unless the intricacies of the social processes underpinning adaptation are taken into explicit consideration in research and policy. Drawing on recent theoretical and empirical studies, the examples highlighted here show that narratives of immunity to the impacts of climate change in developed countries, confidence in technology, and perceived lack of immediacy about climate change impacts have resulted in an unwarranted complacency about adaptation. Effective adaptation strategies should be informed by a deeper understanding of the social process of adaptation and need to address a wide range of barriers.

Heat Waves and Cold Spells: An Analysis of Policy Response and Perceptions of Vulnerable Populations in the UK

Heat waves and cold spells pose ongoing seasonal risks to the health and well-being of vulnerable individuals. Current attempts to address these risks in the UK are implemented through fuel-poverty strategies and heat-wave planning. This paper examines evidence from the UK on whether heat waves and cold spells are addressed differently by public policy in the UK given that risks are mediated by similar perceptions that shape behavioural responses by vulnerable individuals. It is based on a review of UK policies and on a qualitative interview study of risk perceptions of elderly people as a primary identified vulnerable group to these weather extremes. The study involved in-depth repeat interviews with fifteen elderly respondents in summer 2007 and winter 2008 in Norwich (UK). Results suggest that neither heat risks nor cold risks are perceived as personal risks and therefore planned preventive measures by individuals are largely elusive. Cold risk policy reduces vulnerability; policy related to heat relies on early warning and public information programmes and does not reduce underlying vulnerability. Both types of policies largely ignore public perceptions of risks and could benefit from a more cohesive approach, supporting similar measures to reduce seasonal vulnerability.

Planned Adaptation Measures in Industrialised Countries: A Comparison of Select Countries Within and Outside the EU

This chapter provides a context for the discussion on the emergence of adaptation measures in the four case studies presented in this volume through a brief discussion of the ways in which planned adaptations are being developed in eight European countries. Adaptation actions at different levels in Austria, France, Germany, Greece, Hungary, the Netherlands, Norway and Spain are described in order to provide an illustration of adaptation measures in a range of countries representing differing structural contexts, modes of decentralisation and histories of engagement in environmental policy. An additional section on planned adaptation as it has manifested in Canada and Australia is also presented to provide further ground for comparison with countries outside the European context. Results show a tenuous link between the extent to which countries have engaged in adaptation and their environmental policy implementation record, though some interesting links between environmental policy institutions and adaptation can be made. The extent to which unitary and federal nations have decentralised responsibility to sub-national tiers is shown to have an impact on the way in which regions and local authorities have engaged in adaptation. The role of both NGOs and the European Union is shown to be of significance to regional and local governments, as well as those countries who have not yet extensively engaged in adaptation at the national scale.
