A dramatic escalation of extreme climate events is challenging the capacity of environmental governance regimes to sustain and improve ecosystem outcomes. It has been argued that actors within adaptive governance regimes can help to steer environmental systems toward sustainability in times of crisis. Yet there is little empirical evidence of how acute climate crises are navigated by actors operating within adaptive governance regimes, and the factors that influence their responses. Here, we qualitatively assessed the actions key governance actors took in response to back-to-back mass coral bleaching – an extreme climate event – of the Great Barrier Reef in 2016 and 2017, and explored their perceptions of barriers and catalysts to these responses. This research was, in part, a product of collaboration and knowledge co-production with Great Barrier Reef governance actors aimed at improving responses to climate crises in the region. We found five major categories of activity that actors engaged with in the wake of recurrent mass coral bleaching: assessing the scale and extent of bleaching, sharing information, communicating bleaching to the public, building local resilience, and addressing global threats. These actions were both catalyzed and hindered by a range of factors that fall within different domains of adaptive capacity; such as assets, social organization, and agency. We discuss the implications of our findings as they relate to existing research on adaptive capacity and adaptive governance. We conclude by coalescing insights from our interviews and a participant engagement process to highlight four key ways in which the ability of governance actors, and the Great Barrier Reef governance regime more broadly, can be better prepared for, and more effectively respond to extreme climate events. Our research provides empirical insight into how crises are experienced by governance actors in a large-scale environmental system, potentially providing lessons for similar systems across the globe. 相似文献

Climate change is already affecting rural communities along the high Andean plateau, but it is just one of many stresses that Andean people experience on a regular basis. This paper examines the experiences of quinoa farmers in Southwestern Bolivia as they faced the overlapping crises of protracted drought and market disruption in 2017. Drawing on political ecologies of resilience, this paper argues that the ability of rural people to cope with this double exposure was already compromised by ecological and social vulnerabilities produced through the development trajectories of the previous two decades. These development strategies generated three overlapping processes: 1) neoliberal entanglements involving specialization in quinoa production, marketization, and individualization of livelihoods in ways that undermined collective action; 2) new relationships of debt that tied households to monetized response paths and undermined flexibility; and 3) the degradation of soils through extensification, overproduction, and industrialization of quinoa production. This paper argues that while climate and market disruptions are not to be dismissed, we must historicize the double exposure to also ask how resilience and vulnerability to such challenges are generated in the first place. 相似文献

On April 2nd, 2007 a 12 m tsunami struck Simbo, a relatively remote island in Western Province, Solomon Islands. Although Simbo's population continues to depend on their own food production and small-scale governance regimes regulate access to resources, the island's way of life over the last century has increasingly been affected by processes associated with globalization. In this context of a rapidly globalizing world, this article examines the island's resilience and vulnerability to the tsunami and the adaptive capacities that enabled the response and recovery. The tsunami completely destroyed two villages and damaged fringing coral reefs, but casualties were low and social–ecological rebound relatively brisk. By combining social science methods (household surveys, focus group and ethnographic interviews) and underwater reef surveys we identify a number of countervailing challenges and opportunities presented by globalization that both nurture and suppress the island's resilience to high amplitude, low-frequency disturbances like tsunamis. Analysis suggests that certain adaptive capacities that sustain general system resilience come at the cost of more vulnerability to low-probability hazards. We discuss how communities undergoing increasingly complex processes of change must negotiate these kinds of trade-offs as they manage resilience at multiple spatial and temporal scales. Understanding the shifting dynamics of resilience may be critical for Pacific Island communities who seek to leverage globalization in their favor as they adapt to current social–ecological change and prepare for future large-scale ecological disturbances. 相似文献

Despite growing global attention to the development of strategies and policy for climate change adaptation, there has been little allowance for input from Indigenous people. In this study we aimed to improve understanding of factors important in integration of Yolngu perspectives in planning adaptation policy in North East Arnhem Land (Australia). We conducted workshops and in-depth interviews in two ‘communities’ to develop insight into Yolngu peoples’ observations and perspectives on climate change, and their ideas and preferences for adaptation. All participants reported observing changes in their ecological landscape, which they attributed to mining, tourism ‘development’, and climate change. ‘Strange changes’ noticed particularly in the last five years, had caused concern and anxiety among many participants. Despite their concern about ecological changes, participants were primarily worried about other issues affecting their community's general welfare. The results suggest that strategies and policies are needed to strengthen adaptive capacity of communities to mitigate over-arching poverty and well-being issues, as well as respond to changes in climate. Participants believed that major constraints to strengthening adaptive capacity had external origins, at regional, state and federal levels. Examples are poor communication and engagement, top-down institutional processes that allow little Indigenous voice, and lack of recognition of Indigenous culture and practices. Participants’ preferences for strategies to strengthen community adaptive capacity tended to be those that lead towards greater self-sufficiency, independence, empowerment, resilience and close contact with the natural environment. Based on the results, we developed a simple model to highlight main determinants of community vulnerability. A second model highlights components important in facilitating discourse on enhancing community capacity to adapt to climatic and other stressors. 相似文献

The resilience perspective is increasingly used as an approach for understanding the dynamics of social–ecological systems. This article presents the origin of the resilience perspective and provides an overview of its development to date. With roots in one branch of ecology and the discovery of multiple basins of attraction in ecosystems in the 1960–1970s, it inspired social and environmental scientists to challenge the dominant stable equilibrium view. The resilience approach emphasizes non-linear dynamics, thresholds, uncertainty and surprise, how periods of gradual change interplay with periods of rapid change and how such dynamics interact across temporal and spatial scales. The history was dominated by empirical observations of ecosystem dynamics interpreted in mathematical models, developing into the adaptive management approach for responding to ecosystem change. Serious attempts to integrate the social dimension is currently taking place in resilience work reflected in the large numbers of sciences involved in explorative studies and new discoveries of linked social–ecological systems. Recent advances include understanding of social processes like, social learning and social memory, mental models and knowledge–system integration, visioning and scenario building, leadership, agents and actor groups, social networks, institutional and organizational inertia and change, adaptive capacity, transformability and systems of adaptive governance that allow for management of essential ecosystem services. 相似文献

Successful management of socio-ecological systems not only requires the development and field-testing of robust and measurable indices of vulnerability and resilience but also improved understanding of the contextual factors that influence societal capacity to adapt to change. We present the results of an analysis conducted in three coastal communities in Solomon Islands. An integrated assessment map was used to systematically scan the communities’ multiple dimensions of vulnerability and to identify factors affecting households’ perception about their capacity to cope with shocks (resilience). A multivariate probit approach was used to explore relationships amongst factors. Social processes such as community cohesion, good leadership, and individual support to collective action were critical factors influencing the perception that people had about their community's ability to build resilience and cope with change. The analysis also suggests a growing concern for a combination of local (internal) and more global (external) contingencies and shocks, such as the erosion of social values and fear of climate change. 相似文献

There is a growing use of resilience ideas within the disaster risk management literature and policy domain. However, few empirical studies have focused on how resilience ideas are conceptualized by practitioners, as they implement them in practice. Using Hajer's ‘social-interactive discourse theory’ this research contributes to the understanding of how practitioners frame, construct and make sense of resilience ideas in the context of changes in institutional arrangements for disaster risk management that explicitly include the resilience approach and climate change considerations. The case study involved the roll out of the Natural Disaster Resilience Program in Queensland, Australia, and the study involved three sites in Queensland. The methods used were observation of different activities and the physical sites, revision of documents related to the Natural Disaster Resilience Program and in-depth semi-structured interviews with key informants, all practitioners who had direct interaction with the program. The research findings show that practitioners construct the meaning of disaster resilience differently, and these are embedded in diverse storylines. Within these storylines, practitioners gave different interpretations and emphasis to the seven discourse categories that characterized their resilience discourse. Self-reliance emerged as one of the paramount discourse categories but we argue that caution needs to be used when promoting values of self-reliance. If the policy impetus is a focus on learning, research findings indicate it is also pertinent to move from experiential learning toward social learning. The results presented in this study provide helpful insights to inform policy design and implementation of resilience ideas in disaster risk management and climate change, and to inform theory. 相似文献

In recent years, an increasing number of local governments are recognizing the impact of climate change on different urban sectors. This has led many to pursue climate adaptation planning, seeking to achieve preparedness through reducing vulnerability and enhancing resilience of populations, assets, and municipal operations. Although cities typically share these common goals, many are electing to pursue different planning approaches. In this paper, we examine three climate adaptation planning approaches in the cities of Quito (Ecuador), Surat (India), and Durban (South Africa) and analyze the trade-offs associated with different planning pathways and different forms of stakeholder involvement. We assess the potentials and limitations of these different approaches, including their implications for enhancing government integration and coordination, promoting participation and adaptive capacity of vulnerable groups, and facilitating overall urban resilience. We find that, in order to gain widespread commitment on adaptation, sustained political leadership from the top, departmental engagement, and continued involvement from a variety of stakeholders are integral to effective decision-making and institutionalization of programs in the long run. When climate adaptation is advanced with a focus on learning, awareness, and capacity building, the process will likely lead to more sustained, legitimate, and comprehensive adaptation plans and policies that enhance the resilience of the most affected urban areas and residents. 相似文献

The observations of community members and instrumental records indicate changes in sea ice around the Inuit community of Igloolik, in the Canadian territory of Nunavut. This paper characterizes local vulnerability to these changes, identifying who is vulnerable, to what stresses, and why, focusing on local and regional use of sea ice for the harvesting of renewable resources and travel. This analysis is coupled with instrumental and sea ice data to evaluate changing temperature/wind/sea ice trends over time, to complement local observations. We demonstrate the relationships between changing sea ice conditions/dynamics and harvesting activities (i.e. dangers and accessibility), with specific emphasis on ringed seal and walrus seasonal hunting, to illustrate current sea ice exposures that hunters are facing. Community members are adapting to such changes, as they have done for generations. However, current adaptive capacity is both enabled, and constrained, by social, cultural, and economic factors that manifest within the modern northern Hamlet. Enabling factors include the ability of hunters to manage or share the risks associated with sea ice travel, as well as through their flexibility in resource use, as facilitated by sophisticated local knowledge and land/navigational skills. Constraining factors include the erosion of land-based knowledge and skills, altered sharing networks, as well as financial and temporal limitations on travel/harvesting. The differential ability of community members to balance enabling and constraining factors, in relation to current exposures, comprises their level of vulnerability to sea ice change. 相似文献

Avoiding further aggravation of the consequences of global environmental change remains a complex governance challenge. Social relational structure among actors plays a key role for enhancing the capacity of collaborative approaches to environmental governance. We present an encompassing conceptual framework to advance understanding of the mechanisms that shape dynamics in environmental governance entities. Narrative theory is integrated with insights on group dynamics grounded in social network theory to contextualize local social complexities in governance processes. We assume that social relational structure between actors, and narrations they tell, co-produce narratives and dynamics at the group level. Three important mechanisms that influence dynamics are described: (1) the interplay between collaborative relationships and narrative congruence between individual actors, (2) the characteristics of actors, and (3) the actors’ embeddedness in the wider social structure. A set of testable hypotheses on the interplay between narration, narratives and social relational structure in environmental governance processes is presented. We conclude by discussing why we regard this framework useful to study local and regional governance entities in the context of addressing global environmental change. 相似文献

Adaptation is a complex, dynamic, and sometimes unequal process. Stemming from social ecological systems theories of climate change adaptation and adaptive capacity, this case study introduces the concept of ‘divergent’ adaptation. Adaptation is divergent when one user or group's adaptation causes a subsequent reduction in another user or group's adaptive capacity in the same ecosystem. Using the example of pastoral and agricultural groups in northern and southern rainfall zones of Niger, this study illustrates the concept of divergent adaptation by identifying changes to the adaptive capacity of users who are currently engaged in conflicts over access to natural resources. Similar to other studies, we find that expansion of farmland and the consequent loss of pastoral space are restricting pastoral adaptation. Divergent adaptations favoring agricultural livelihoods include cultivating near or around pastoral wells or within pastoral corridors, both of which limit the mobility and entitlements of pastoralists. Institutions rarely secure pastoral routes and access to water points, a problem that is compounded by conflicting modes of governance, low accountability, and corruption. The case study illustrates the need to enhance the adaptive capacity of multiple user groups to reduce conflict, enhance human security, and promote overall resilience. 相似文献

Urban water systems need to serve increasing numbers of people under a changing climate. Studies of systems facing extreme events, such as drought, can clarify the nature of adaptive capacity and whether this might support incremental (marginal changes) or transformative adaptation (fundamental system shifts) to climate change. We conducted comparative case studies of three major metropolitan water systems in the United States to understand how actions taken in response to drought affected adaptive capacity and whether the adaptive capacity observed in these systems fosters the preconditions needed for transformative adaptation. We find that while there is ample evidence of existing and potential adaptive capacity, this can be either enabled or diminished by the specific actions taken and their cascading effects on other parts of the system. We also find social dimensions, such as public acceptance, learning, trust, and collaboration, to be as critical as physical elements of adaptive capacity in urban water systems. Finally, we suggest that changes in practices initiated during drought, combined with sustained engagement, collaboration, and education, can lead to substantial and long-lasting changes in values around water, a precursor to transformative adaptation. 相似文献

Small-scale fisheries in developing regions are particularly vulnerable to climate change, but the assessment of climate-induced changes and impacts are often hampered by the data poor-situation of these social-ecological systems. Based on 40 years of scientific and local ecological knowledge, we provide a coherent narrative about the effects of a marine hotspot of climate change on a small-scale fishery across different geographical and temporal scales. We applied a mixed-methods approach to assess biophysical changes, social-ecological impacts, and the incremental spectrum of actions implemented at multiple levels to increase the adaptive capacity of a small-scale clam fishery. The warming hotspot here analyzed was the fastest-warming region in the South Atlantic Ocean. Long-term changes in wind intensity and direction were also noticeable at a regional scale. Both sea surface temperature and winds showed a clear shifting pattern in the late 1990 s. These climate-related stressors determined ecosystem and targeted population changes (e.g. clam mass mortalities, slow stock recovery rates after ecological shocks, habitat narrowing), and favored harmful algal bloom-forming organisms. Climate-induced drivers also affected the human component of the social-ecological system, preventing fishers from securing a fulltime livelihood and limiting the fishery economic potential. Adaptive responses at multiple levels provided some capacity to address climate change effects, and transformative pathways are being taken to adapt to climate-induced changes over the long-term. Transformative changes were fostered by the local perception of environmental change, shared narratives, sustained scientific monitoring programs, and the interaction between knowledge systems, facilitated by a bridging organization within a broader process of governance transformation. The combination of autonomous adaptations (based on linking social capital and fishery leaders agency) and government-led adaptations were essential to face the challenges imposed by climate change. Our results serve as a learning platform to anticipate threats and envision solutions to a wide range of small-scale fisheries in fast-warming regions worldwide. 相似文献

This paper examines contemporary national scale responses to tropical storm risk in a small island in the Caribbean to derive lessons for adapting to climate change. There is little empirical evidence to guide national planners on how to adapt to climate change, and less still on how to build on past adaptation experiences. The paper investigates the construction of institutional resilience and the process of adaptation to tropical storm risk by the Cayman Islands’ Government from 1988 to 2002. It explains the roles of persuasion, exposure and collective action as key components in developing the ability to buffer external disturbance using models of institutional economics and social resilience concepts. The study finds that self-efficacy, strong local and international support networks, combined with a willingness to act collectively and to learn from mistakes appear to have increased the resilience of the Cayman Islands’ Government to tropical storm risk. The lessons learned from building resilience to storm risk can contribute to the creation of national level adaptive capacity to climate change, but climate change has to be prioritised before these lessons can be transferred. 相似文献

Ecosystem stewardship is a framework for actively shaping trajectories of ecological and social change to foster a more sustainable future for species, ecosystems, and society. We apply this framework to conservation challenges and opportunities in the Arctic, where the rapid pace of human-induced changes and their interactions force us now to consider a new relationship between people and the rest of nature. Biodiversity, which has traditionally been the target of conservation efforts, is increasingly affected by human impacts such as energy demand and industrial development that are motivated more by short-term profits than by concerns for societal consequences of long-term arctic biodiversity change. We posit that effective approaches to conservation must (a) foster both ecosystem resilience and human wellbeing, (b) integrate ecological and social processes across scales, and (c) take actions that shape the future rather than seeking only to restore the past. To this end, we identify progress through actions that have been or could be taken at local, national, and international scales to promote arctic resilience and conservation. A stewardship approach to conservation aims to prevent undesirable changes and prepares for adaptation to rapid and uncertain changes that cannot be avoided and for transformation to avoid or escape undesirable states. The greatest opportunity for arctic stewardship at the local scale may lie in building upon culturally engrained (often indigenous) respect for nature and reliance on local environment, empowering it through knowledge and power sharing with national regulatory frameworks. This, in turn, allows connection of drivers with impacts across scales and raises awareness of the value of human–environment relationships. At national and international scales stewardship provides rules for coordinated action to reconcile local and regional conservation actions with those that are motivated by constraints at the global level, to foster ecosystem integrity and human wellbeing in the face of transformative changes in environment, landscapes, species, and society. 相似文献

Smallholder farmers continuously confront multiple social and environmental stressors that necessitate changes in livelihood strategies to prevent damages and take advantage of new opportunities, or adaptation. Vulnerability, meaning susceptibility to harm, is attributable to social determinants that limit access to assets, leading to greater exposure and sensitivity to stressors and a limited capacity to adapt. Stressors and adaptation are intertwined because stressors deplete resources available for adaptation, while adaptation may erode resources available to respond to future stressors. We present empirical evidence demonstrating the interactions of multiple stressors and adaptations over time through a case study of indigenous farmers in highland Bolivia. We examine how farmers perceive the stress on their livelihoods, their strategies for adapting to these threats, and the influence of past adaptation and exposure on vulnerability under increasing climatic change. We find that vulnerability changes over time as multiple stressors, such as land scarcity and delayed seasonal rainfall, compound, simultaneously reducing access and demanding the expenditure of household assets for adaptation, including natural capital (water and land), human capital (including labor), and financial, physical, and social capital. To reduce vulnerability over time, constraints on access to key resources must be addressed, allowing households the flexibility to reduce their exposure and improve their adaptive capacity to the multiple stressors they confront. 相似文献

Within the wide array of adaptive responses to flood hazards, planned relocation of residents at risk is usually only taken into account if other responses are ineffective or unavailable. Residents targeted by planned relocation are confronted with radical changes in their livelihood; therefore, relocation is highly contested within public risk discourse. The present paper assesses dynamic processes in the design and implementation of voluntary planned relocation in the Austrian Danube catchment over five decades. Using the Multiple Streams Approach, the emergence of policy windows is mapped to developments in the problem, political, policy and population streams. A mixed-methods design combines semi-structured interviews of 88 affected households and 21 decision-makers with archival research. Repeated flood events underscored that standard protection did not suffice for all riverside communities. In consequence, national authorities acted as policy entrepreneurs to advocate planned relocation and direct the discourse; by contrast, local stakeholders and residents played a mostly passive role. The relocation policy developed from ad-hoc informal arrangements towards a formalised procedure. Relocation governance evolved as incremental change over a long time span instead of immediate, radical disruption. Policy acceptance by residents depended crucially on social learning and on coincidence with personal circumstances and biographical stages. Policy windows opened for several years, when pre-signals from ongoing public debate accumulated and the different timescales in the decision-making of public administrators, elected representatives and residents aligned. Key factors were long-term perspective, flexibility, engagement and social capacity at a local level to deal with and manage planned relocation. 相似文献

The influence of socio-cultural factors on the adaptive capacity, resilience and trade-offs in decision-making of households and communities is receiving growing scholarly attention. In many partly transformed societies, where the market economy is not well developed, livelihood practices are heavily structured by kinship and indigenous social and economic values. Farm investment decisions and incentives to produce agricultural commodities are shaped by a host of considerations in addition to market imperatives like profit. In one such partly transformed society in East New Britain Province, Papua New Guinea, we examine the adaptation decisions of smallholders in response to the drastic drop of yield in their cocoa plots caused by the sudden outbreak of Cocoa Pod Borer. To explain why the impact of the pest has been so great we examine the interconnections between household responses, the local socio-cultural and economic context of smallholder commodity crop production and the wider institutional environment in which household choices and decisions are made. We argue that the significant lifestyle changes and labour intensive farming methods required for the effective control of Cocoa Pod Borer are incompatible with existing smallholder farming systems, values and livelihoods. To adopt a high input cropping system requires more than a technical fix and some training; it also requires abandoning a ‘way of life’ that provides status, identity and a moral order, and which is therefore highly resistant to change. The paper highlights the enduring influence and significance of local, culturally-specific beliefs and socio-economic values and their influence on how individuals and communities make adaptation decisions. 相似文献

Multi-level, networked participation is a vital component in building social–ecological resilience and the capacity to adapt to environmental change. This paper outlines the ways in which multi-level participation contributes to adaptive capacity and, in so doing, takes a step toward articulating a theory of participation based on resilience thinking. We use a case study of Gabra pastoralist communities of northern Kenya to illustrate how multi-level participation may lead to increasing adaptive capacity, above and beyond existing pastoralist adaptations. The findings suggest that adaptive capacity is systemic—that is to say, it is a property of the social–ecological system, including especially the network of institutional linkages that characterizes that system, as much as it is a property of particular actors within the system. We argue that there are three key elements of meaningful multi-level participation: an institutional environment in which the various levels of institutions are linked, inclusivity in decision-making at these various levels, and deliberation. These three features can work together to create meaningful multi-level participation, to facilitate the co-production of knowledge and to build adaptive capacity. 相似文献
