The impending form and extent of climate change and its direct impacts present disproportionate challenges for the most socially and economically disadvantaged groups within populations. Evaluating the vulnerability of disadvantaged groups in the context of climate change has presented tremendous theoretical, methodological and policy challenges especially where vulnerability assessment research is focused at the local community level. This study addresses the challenges by developing an interdisciplinary methodology, based on expert knowledge, and uses the state of South Australia as a case study. It focuses on key indicators that measure the exposure of local communities to climate change and socio-economic vulnerabilities of local populations. A main contribution in this study is the novel incorporation of physical, environmental and socio-demographic data sets and extensive use of spatial modelling and estimation methods to spatially define climate change and social vulnerability “hot spots”. This paper assesses vulnerability under moderate and high Intergovernmental Panel on Climate Change CO2 emission scenarios in order to generate an assessment model to be used before planning is done. The result is the creation of a practical tool through which decision-makers can better understand how the complexity of one's local spatial context influences the unique exposure, which different vulnerable communities have, to the impacts of climate change. This paper presents a useful tool that can be used in the initial assessment phase by planners and policy-makers to better assist those who are limited in their ability to adapt to climate change.  相似文献

This study explores potential adaptation approaches in planning and management that the United States Forest Service might adopt to help achieve its goals and objectives in the face of climate change. Availability of information, vulnerability of ecological and socio-economic systems, and uncertainties associated with climate change, as well as the interacting non-climatic changes, influence selection of the adaptation approach. Resource assessments are opportunities to develop strategic information that could be used to identify and link adaptation strategies across planning levels. Within a National Forest, planning must incorporate the opportunity to identify vulnerabilities to climate change as well as incorporate approaches that allow management adjustments as the effects of climate change become apparent. The nature of environmental variability, the inevitability of novelty and surprise, and the range of management objectives and situations across the National Forest System implies that no single approach will fit all situations. A toolbox of management options would include practices focused on forestalling climate change effects by building resistance and resilience into current ecosystems, and on managing for change by enabling plants, animals, and ecosystems to adapt to climate change. Better and more widespread implementation of already known practices that reduce the impact of existing stressors represents an important “no regrets” strategy. These management opportunities will require agency consideration of its adaptive capacity, and ways to overcome potential barriers to these adaptation options.  相似文献

This paper directs attention to conditions for climate adaptation as an important part of governing climate change in the local arena. Empirical focus is put on attempts to manage flood risks by means of risk management and planning in two Swedish municipalities. Following the need to widen our understanding of how, when and under what conditions climate adaptation occurs, three challenges are particularly emphasized from the case studies: facing the safety vs. scenery conflict where political priorities and reducing societal vulnerabilities prove difficult; the process of deciding what to adapt to, in which the troublesome role of knowledge is striking; and finally, taking responsibility for measures of flood protection. At the end of the paper, analytical generalizations illustrate the need to give increased attention to institutional challenges and challenges emanating from the science-policy interface in order to come to terms with the implementation deficit in governing climate change in the local arena.  相似文献

The coupled processes of climate change and urbanization pose challenges for water resource management in cities worldwide. Comparing the vulnerabilities of water systems in Phoenix, Arizona and Portland, Oregon, this paper examines (1) exposures to these stressors, (2) sensitivities to the associated impacts, and (3) adaptive capacities for responding to realized or anticipated impacts. Based on a case study and survey-based approach, common points of vulnerability include: rising exposures to drier, warmer summers, and suburban growth; increasing sensitivities based on demand hardening; and limited capacities due to institutional and pro-growth pressures. Yet each region also exhibits unique vulnerabilities. Comparatively, Portland shows: amplified exposures to seasonal climatic extremes, heightened sensitivity based on less diversified municipal water sources and policies that favor more trees and other irrigated vegetation, and diminished adaptive capacities because of limited attention to demand management and climate planning for water resources. Phoenix exhibits elevated exposure from rapid growth, heightened sensitivities due to high water demands and widespread increases in residential and commercial uses, and limited adaptive capacities due to weak land use planning and “smart growth” strategies. Unique points of vulnerability suggest pathways for adapting to urban-environmental change, whether through water management or land planning. Greater coordination between the land and water sectors would substantially reduce vulnerabilities in the study regions and beyond.  相似文献

It has been argued that regional collaboration can facilitate adaptation to climate change impacts through integrated planning and management. In an attempt to understand the underlying institutional factors that either support or contest this assumption, this paper explores the institutional factors influencing adaptation to climate change at the regional scale, where multiple public land and natural resource management jurisdictions are involved. Insights from two mid-western US case studies reveal that several challenges to collaboration persist and prevent fully integrative multi-jurisdictional adaptation planning at a regional scale. We propose that some of these challenges, such as lack of adequate time, funding and communication channels, be reframed as opportunities to build interdependence, identify issue-linkages and collaboratively explore the nature and extent of organisational trade-offs with respect to regional climate change adaptation efforts. Such a reframing can better facilitate multi-jurisdictional adaptation planning and management of shared biophysical resources generally while simultaneously enhancing organisational capacity to mitigate negative effects and take advantage of potentially favourable future conditions in an era characterised by rapid climate change.  相似文献

The potential impacts of climate change are varied and highly uncertain, and pose a significant challenge to agencies charged with managing environmental risks. This paper presents a comprehensive and structured Mental Modeling approach to elicit, organize and present relevant information from experts and stakeholders about the factors influencing environmental risk management in the face of climate change. We present and review an initiative undertaken by the United States Army Corps of Engineers (USACE) to characterize climate change challenges to USACE environmental risk management activities, and to identify gaps with respect to science, engineering, and organizational processes for addressing these challenges. By employing Mental Modeling, the research has characterized the influences of climate change on USACE environmental risk management, and aggregating recommendations from 28 experts. In addition, the study identifies the most important opportunities to improve organizational response to climate change, ranging from focused research and development of technical capabilities to broad paradigm shifts and systemic organizational improvements within the USACE environmental risk management programs. This study demonstrates that Mental Modeling is a useful tool for understanding complex problems, identifying gaps, and formulating strategies, and can be used by a multitude of organizations and agencies.  相似文献

Impacts from climate change pose a raft of challenges for societies, governments and policy-makers internationally. The anticipated changes are well documented, including rising sea levels, increased floods and other extreme weather conditions. Much research and policy emphasis has focused on technical and economic aspects. Less debated are questions about different communities' vulnerabilities, inequitable distributional impacts, social justice issues and how vulnerability links to social inclusion/exclusion. This paper explores a case study mapping social exclusion and vulnerability in Brisbane, Queensland, which found that while communities can be vulnerable through physical aspects of an area when social dimensions are added to the equation it amplifies or exacerbates the scale of vulnerability. The findings also suggest that in developing research agendas and policy debates around climate change, there could be benefits from interlinking the currently separate areas of work on social vulnerability to extreme weather events, to forms and processes of social inclusion/exclusion.  相似文献

Public lands and waters in the United States traditionally have been managed using frameworks and objectives that were established under an implicit assumption of stable climatic conditions. However, projected climatic changes render this assumption invalid. Here, we summarize general principles for management adaptations that have emerged from a major literature review. These general principles cover many topics including: (1) how to assess climate impacts to ecosystem processes that are key to management goals; (2) using management practices to support ecosystem resilience; (3) converting barriers that may inhibit management responses into opportunities for successful implementation; and (4) promoting flexible decision making that takes into account challenges of scale and thresholds. To date, the literature on management adaptations to climate change has mostly focused on strategies for bolstering the resilience of ecosystems to persist in their current states. Yet in the longer term, it is anticipated that climate change will push certain ecosystems and species beyond their capacity to recover. When managing to support resilience becomes infeasible, adaptation may require more than simply changing management practices—it may require changing management goals and managing transitions to new ecosystem states. After transitions have occurred, management will again support resilience—this time for a new ecosystem state. Thus, successful management of natural resources in the context of climate change will require recognition on the part of managers and decisions makers of the need to cycle between “managing for resilience” and “managing for change.”  相似文献

Water utilities that rely on surface water may be vulnerable to future droughts and floods, a vulnerability that may be magnified by climate perturbations as well as shorter-term and, in some cases, ongoing changes in the political and regulatory environment in which utilities operate. Unfortunately, day-to-day responsibilities currently occupy most utility operators, leaving little time to plan for inherently uncertain effects. The record of actual responses to past droughts and floods can be illuminating, however, particularly when placed in the context of plausible hydrologic disruption and pressures such as population growth, floodplain development and new regulatory demands. This paper draws on interviews with water utility operators in the northwestern USA to highlight opportunities and constraints that water utilities may face vis-à-vis such disruptions. Key considerations affecting vulnerabilities include water rights, institutional barriers to efficient utility operations, hazard management policy and the fiscal status of utilities.  相似文献

In the midst of rapidly proliferating engagement efforts around climate adaptation, attention to the design and evaluation of decision support processes and products is warranted. We report on the development and evaluation of a process framework called the Vulnerability, Consequences, and Adaptation Planning Scenarios (VCAPS) process. VCAPS is a systematic approach to integrate local knowledge with scientific understanding by providing opportunities for facilitated, deliberative learning-based activities with local decision makers about climate change vulnerability and adaptation. We introduce the conceptual basis of the process in analytic-deliberation, hazard management, and vulnerability. Our evaluations from eight coastal communities where the approach was applied point to four assets of VCAPS: it promotes synthesis of local and scientific knowledge; it stimulates systems thinking and learning; it facilitates governance by producing action plans with transparent justifications; and it accommodates participant time constraints and preferences.  相似文献

Local governments are under pressure to tackle an increasing spectrum of complex contemporary problems, such as climate change, while ensuring multiple stakeholder interests are incorporated into decision processes. Multi-criteria decision tools can assist, but challenges remain in creating an enabling environment for incorporating and balancing different stakeholder perspectives. Here, we draw on interview data and a sensitivity analysis to investigate the use of an evaluation matrix to guide local coastal adaptation decision-making in South Africa. We adopt a participatory action research framework and find that decision-making is influenced by individual, departmental and institutional values that are not adequately captured in the matrix approach. Our study reveals the compromise between achieving broad stakeholder representation and utilising technical expertise, and that altering matrix assumptions can imply different decision outcomes. Suggestions are made to improve multi-criteria decision approaches to better facilitate integrated coastal management in responding to local coastal adaptation challenges.  相似文献

In the Wasatch Range Metropolitan Area of Northern Utah, water management decision makers confront multiple forms of uncertainty and risk. Adapting to these uncertainties and risks is critical for maintaining the long‐term sustainability of the region's water supply. This study draws on interview data to assess the major challenges climatic and social changes pose to Utah's water future, as well as potential solutions. The study identifies the water management adaptation decision‐making space shaped by the interacting institutional, social, economic, political, and biophysical processes that enable and constrain sustainable water management. The study finds water managers and other water actors see challenges related to reallocating water, including equitable water transfers and stakeholder cooperation, addressing population growth, and locating additional water supplies, as more problematic than the challenges posed by climate change. Furthermore, there is significant disagreement between water actors over how to best adapt to both climatic and social changes. This study concludes with a discussion of the path dependencies that present challenges to adaptive water management decision making, as well as opportunities for the pursuit of a new water management paradigm based on soft‐path solutions. Such knowledge is useful for understanding the institutional and social adaptations needed for water management to successfully address future uncertainties and risks.  相似文献

Sorsogon City is a rapidly urbanising coastal area in the Philippines. Its location, combined with a rapidly changing and growing urban fabric, leaves it vulnerable to both incremental climate change and associated extreme weather events. In this paper, UN-HABITAT data are used to draw out the climate change vulnerabilities and policy responses in Sorsogon City. Vulnerability “hotspots” highlight the spatial intersection of socio-economic justice concerns, particularly in terms of vulnerability to increased cyclone activity. We discuss vulnerabilities of Sorsogon City and its citizens to climate change and measures undertaken through various social, environmental and technical systems and interventions to increase resilience. The paper also attempts to unpick the relationship between the neat, concise reported city and the complexities of urban life using the Sorsogon experiment to consider the limitations of such approaches to governing climate change. We group these under four headings: social simplification in the absence of data; over-governance (and under-representation); quick wins versus strategic investment; and stretching the ecological and vulnerability footprints of the city. The experience of Sorsogon City is then extended to reflect on issues of governance and planning in other Asian coastal cities.  相似文献

Nordic agriculture must adapt to climate change to reduce vulnerability and exploit potential opportunities. Integrated assessments can identify and quantify vulnerability in order to recognize these adaptation needs. This study presents a geographic visualization approach to support the interactive assessment of agricultural vulnerability to climate change. We have identified requirements for increased transparency and reflexivity in vulnerability assessments, arguing that these can be met by geographic visualization. A conceptual framework to support the integration of geographic visualization for vulnerability assessments has been designed and applied for the development of AgroExplore, an interactive tool for assessing agricultural vulnerability to climate change in Sweden. To open up the black box of composite vulnerability indices, AgroExplore enables the user to select, weight, and classify relevant indicators into sub-indices of exposure, sensitivity, and adaptive capacity. This enables the exploration of underlying indicators and factors determining vulnerability in Nordic agriculture.  相似文献

ABSTRACT

Cities, with their increasing populations, are host to a range of issues including non-climatic factors due to the prevailing development paradigm, discriminatory urbanisation patterns, and weak governance structures. Climate change poses an additional challenge and exacerbates existing vulnerabilities affecting cities and its people, especially the urban poor. This paper highlights the barriers and enablers to climate change-related adaptation experienced in some of Bengaluru’s informal settlements. The barriers described in the paper include economic, social, governance and information related issues that impede local actions and increase vulnerabilities. Enabling factors such as improving social and human capital, gaining formal recognition and most importantly support from agencies (e.g. local government, civil societies, and community leaders), help overcome some of the barriers or challenges. Hence, local level adaptation measures mainstreamed with local developmental agendas help address some of the structural causes of vulnerability. Contextual policies and interventions can facilitate successful local level adaptation measures.  相似文献

How do Local Governments in Mexico City Manage Global Warming?   总被引:1,自引:0,他引:1  
《Local Environment》2007,12(5):519-535
Cities are both significant emitters of carbon dioxide and centres of innovations that may contribute to de-carbonizing our societies. More voices claim therefore that local authorities should be included in efforts to mitigate climate change. However, few studies have analysed how local authorities manage carbon and climate in urban areas in middle- and low-income countries. Yet, the institutional settings and governance structures of such cities are different from those prevailing in cities of wealthy countries. This paper aims to fill this gap by exploring: (a) whether and—if so—how local authorities in Mexico City actually 'manage' carbon emissions; (b) how the city's evolving governance structures function and whether they 'fit' with the problem they address; and (c) how institutional capacity constrains authorities' management efforts. The paper suggests that policy networks and research groups have been critical in launching a climate agenda. Nevertheless, this has not been enough to push effective policies. Policymaking has been constrained by two sets of institutional factors: the problem of fit and a lack of institutional capacity.  相似文献

Climate change-related impacts have the capacity to substantially influence Small Island Developing States (SIDS) in the Caribbean. Currently, many SIDS are engaged in large-scale vulnerability assessments that aim to identify, analyse, and inform solutions to mitigate climate change-related impacts. Many of these assessments, while useful, place little emphasis on the local stakeholders' perceptions of climate change. One such Caribbean community impacted by climate-related change is Providence Island in Colombia. Using a vulnerability assessment framework (Marshall, P.A. et al. 2010. A framework for social adaptation to climate change: sustaining tropical coastal communities and industries. Gland: IUCN Publication Services), researchers interviewed island residents (N = 23) about their perceptions of climate change, impacts on the local environment, and how the island community may adapt. All interviews were transcribed and analysed using a priori and open coding to identify patterns of and relationships between stakeholders' responses. Results indicate that local perceptions of climate change are linked to (1) environmental knowledge, (2) environmental awareness, attitudes, and beliefs, and (3) perceptions of risk. Implications for local adaptive strategies, education, communication, and suggestions for engagement at the local level are discussed.  相似文献

The Covenant of Mayors has secured the commitments of over 5400 European Cities (as of December 2013) to achieving the European Union 20-20-20 climate change mitigation targets by 2020 through action at the local level. Due to the youth of the initiative, few experiences have been reported in the academic literature. We study the development of the Sustainable Energy Action Plan (SEAP) in the city of Girona (Catalonia, Spain) to analyse the opportunities and challenges this process may present in a small- to medium-sized, compact Mediterranean city. This knowledge can provide information to local authorities in similar municipalities, technical teams and decision-makers at the European level interested in enhancing the performance of such plans in the future. In this article, we explain how the SEAP was developed in Girona, the main results and proposed actions, and discuss the main setbacks. We conclude that an overarching European oversight organism is advisable to coordinate and aid local efforts.  相似文献

This study focuses on the potential role of technical and institutional innovations for improving water management in a multi-user context in Burkina Faso. We focus on a system centered on three reservoirs that capture the waters of the Upper Comoé River Basin and servicing a diversity of users, including a sugar manufacturing company, a urban water supply utility, a farmer cooperative, and other downstream users. Due to variable and declining rainfall and expanding users’ needs, drastic fluctuations in water supply and demand occur during each dry season. A decision support tool was developed through participatory research to enable users to assess the impact of alternative release and diversion schedules on deficits faced by each user. The tool is meant to be applied in the context of consultative planning by a local user committee that has been created by a new national integrated water management policy. We contend that both solid science and good governance are instrumental in realizing efficient and equitable water management and adaptation to climate variability and change. But, while modeling tools and negotiation platforms may assist users in managing climate risk, they also introduce additional uncertainties into the deliberative process. It is therefore imperative to understand how these technological and institutional innovations frame water use issues and decisions to ensure that such framing is consistent with the goals of integrated water resource management.  相似文献
