Adaptation Strategies for Climate Change in the Urban Environment: Assessing Climate Change Related Risk in UK Urban Areas

This paper presents a conurbation‐scale risk assessment methodology which aims to provide a screening tool to assist with planning for climate change‐related risks in the urban environment. This work has been undertaken as part of a wider, interdisciplinary project, Adaptation Strategies for Climate Change in the Urban Environment (ASCCUE). The main focus of ASCCUE is to help improve understanding of the consequences of climate change for urban areas and how these, and the neighbourhoods within them, can best be adapted. Adaptation options will be explored in the context of both conurbation‐scale strategic planning and neighbourhood‐level urban design. The paper conveys some of the initial outputs from the ASCCUE project. It firstly presents the overarching risk assessment framework, before outlining the GIS‐based elements of the methodology. This draws on a characterisation of the urban area into distinctive “urban morphology units” as the spatial framework for the analytical work. An example of heat related risk is given by way of an illustrative application of the methodology. The paper concludes with a consideration of the limitations of the approach and how some of these will be tackled as part of the ongoing work programme.

Resilience and Climate Change Adaptation: The Importance of Framing

In the Australian policy context, there has recently been a discernible shift in the discourse used when considering responses to the impacts of current weather extremes and future climate change. Commonly used terminology, such as climate change impacts and vulnerability, is now being increasingly replaced by a preference for language with more positive connotations as represented by resilience and a focus on the ‘strengthening’ of local communities. However, although this contemporary shift in emphasis has largely political roots, the scientific conceptual underpinning for resilience, and its relationship with climate change action, remains contested. To contribute to this debate, the authors argue that how adaptation is framed—in this case by the notion of resilience—can have an important influence on agenda setting, on the subsequent adaptation pathways that are pursued and on eventual adaptation outcomes. Drawing from multi-disciplinary adaptation research carried out in three urban case studies in the State of Victoria, Australia (‘Framing multi-level and multi-actor adaptation responses in the Victorian context’, funded by the Victorian Centre for Climate Change Adaptation Research (2010–2012)), this article is structured according to three main discussion points. Firstly, the importance of being explicit when framing adaptation; secondly, this study reflects on how resilience is emerging as part of adaptation discourse and narratives in different scientific, research and policy-making communities; and finally, the authors reflect on the implications of resilience framing for evolving adaptation policy and practice.

Changes to climate and visitor behaviour: implications for vulnerable landscapes in the North West region of England.

Many high quality landscapes can be found in the North West region of England, including those of international significance such as the Lake District National Park. These natural assets are recognised by the regional tourism strategy as particularly important, as they are a major determinant for visitors within, and to, the region. However, with the strategy geared towards increasing visitor numbers, there is a substantial challenge to be faced in the future: how to maintain the quality of an environment that is under combined pressure from both visitor numbers and climate change? Focusing on two landscape types considered to be the most vulnerable to a changing climate, the coastal zone and the uplands, this paper presents ‘downscaled’ climate change scenarios, and provides an assessment of how a combination of climate and non-climate factors are likely to impact these vulnerable landscapes in the future. The case study analysis is largely drawn from a series of ‘risk’ workshops held with key regional stakeholders.

The impact of the 2009 heat wave on Melbourne's critical infrastructure

The impact of the extreme heat wave that affected Melbourne, Australia, in two distinct phases in January and February 2009 was severe, with 374 (heat) and 173 (bushfire) excess deaths. Whilst the human health issues have been covered in detail in policy and academic arenas, much less attention has been paid to the adverse impacts on urban infrastructure. Analysis of this event, underpinned by participatory actor-based research, has shown that the impacts were experienced disproportionately across different infrastructure types. For water, telecommunications and airports, the impacts were relatively minor and the impact on rail transport and roads (and to a lesser extent, seaports) was of moderate significance, whereas research findings indicate that the electricity sector was found to be the most vulnerable. This paper focuses on the sectors that were worst impacted: electricity, rail and road transport. Commentary identifies the direct and indirect impacts of the heat event, including associated cascading effects, as well as considering actual and potential adaptation responses both before and after the event. Concluding, the authors reflect on the implications of the heat wave for urban resilience, emphasising the crucial importance of understanding the urban environment as a complex and interconnected system.

Urban Sustainability: Problems Facing the ‘Local’ Approach to Carbon-Reduction Strategies

Urban policies which include energy and environmental objectives are seen as potentially effective instruments in the quest for urban sustainability. Recent consensus is that the modern city region forms an important focal point for assessment and implementation of energy strategies, facilitating practical solutions to local problems as well as providing beneficial additions to national policies. Reducing the carbon intensity of economies both prevents environmental degradation and supports the regional economy in the medium to long term. The authors look at the construction of a CO2 inventory for the Greater Manchester region, an urban conurbation set for economic growth after recent restructuring and diversification. The authors argue that, by providing an indication of the localised carbon flows specific to the region, it is possible to target problem areas, prioritise carbon-reduction strategies, and recommend policies that will case the transition to a more sustainable urban settlement. The increased focus on finding ‘local’ solutions to the reduction of carbon intensity has coincided with privatisation of much of the energy industry. The newly competitive energy market conflicts with the shift to local-scale evaluations and has resulted in energy details at the regional level becoming increasingly harder to obtain. The problems experienced in the construction of this inventory will be common to other cities in the United Kingdom and will have to be addressed if the ‘local’ approach is to be as effective as is hoped.

Climate change, equity and the Sustainable Development Goals: an urban perspective

Climate change is acknowledged as the largest threat to our societies in the coming decades, potentially affecting large and diverse groups of urban residents in this century of urbanization. As urban areas house highly diverse people with differing vulnerabilities, intensifying climate change is likely to shift the focus of discussions from a general urban perspective to who in cities will be affected by climate change, and how. This brings the urban equity question to the forefront. Here we assess how climate change events may amplify urban inequity. We find that heatwaves, but also flooding, landslides, and even mitigation and adaptation measures, affect specific population groups more than others. As underlying sensitivity factors we consistently identify socioeconomic status and gender. We synthesize the findings with regard to equity types – meaning outcome-based, process-oriented and context-related equity – and suggest solutions for avoiding increased equity and justice concerns as a result of climate change impacts, adaptation and mitigation.

Cross-border organisations as an adaptive water management response to climate change: the case of the Guadiana river basin

In this paper we analyse the role played by cross-border organisations in the Guadiana river basin in Iberia, and the extent to which new emerging institutional arrangements carry on adaptive management practice as a response to mounting climate change risks in the river basin. Particular attention is paid to the new transboundary agencies, as promoted by the EU INTERREG programmes, and their potential for mainstreaming climate change considerations into Guadiana river basin development strategies. Results indicate that the penetration of climate change concerns into regional development policies requires a better integration of different policies and improved connectivity and coordination between multiple actors operating across sectors, and at different spatial scales. We argue that the emergence of new transboundary agencies capable of performing these bridging functions is a vital ingredient for building climate adaptive capacity in these cross-border regions.

Toolkits for regional sustainable development

T HIS SPECIAL ISSUE is dedicated to work informing the new regional agenda for sustainable development. Whichever definition is applied to sustainable development, the authors suggest that an integrated and long-term approach is an essential element of any strategy. In practice, however, they argue that the majority of policy and action is short-term and fragmented between sectors and stakeholders. To address these shortcomings, and to facilitate ‘joined-up’ thinking and action, it is increasingly clear that we need new kinds of information systems and communication channels to promote positive change. The papers in this issue were presented at the ‘Toolkits for Sustainable Development’ seminar, a research-practitioner workshop held at the Centre for Urban and Regional Ecology, Manchester, UK1 in September 2000. It aimed to bring together best practice from research and policy communities in an action-research format, reviewing the state of the art and generating tangible outputs, with a dual approach:

Adaptation and Mainstreaming of EU Climate Change Policy: An Actor-Based Perspective

Adaptation to climate change (in comparison to the mitigation agenda) is a relatively new focus for both research and policy communities. Drawing from ongoing ‘actor-based’ research being carried out for the ADAM project, this briefing paper reports on the knowledge base being developed through a process of engagement with experts and key stakeholders across a variety of countries, landscape types, sectors, institutions and actors. The concluding discussion then focuses on some of the implications of these early findings for both EU policy and decision-making more generally.

The Prospects for Improved Energy Efficiency in the UK Residential Sector

The perceived threat of climate change has become an important global issue of the 1990s, with measures to limit its ramifications now commonly linked to mainstream policy agendas. Reducing carbon intensity can be achieved through both supply and end-use energy strategies, though improvements in end-use efficiency are said to offer the best opportunities both in terms of effective investment and producing results in the short to medium term. UK policy makers have stressed that energy use in the home is a pressing area to be addressed. This paper reviews the myriad of efficiency options available, assessing the effectiveness of national and supra-national strategies in encouraging technical efficiency and stimulating beneficial behaviourial changes. Findings indicate that the range of (and commitment to) current efficiency measures, reinforced by a lack of policy coherence, ensures that future prospects remain ambiguous. Initiatives, though conceived at a variety of spatial scales, tend to be implemented at a localized level and it is the actions (and interactions) of local actors that may well determine the shape and success of sustainability measures.
