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

Vulnerability   总被引:12,自引:0,他引:12  
This paper reviews research traditions of vulnerability to environmental change and the challenges for present vulnerability research in integrating with the domains of resilience and adaptation. Vulnerability is the state of susceptibility to harm from exposure to stresses associated with environmental and social change and from the absence of capacity to adapt. Antecedent traditions include theories of vulnerability as entitlement failure and theories of hazard. Each of these areas has contributed to present formulations of vulnerability to environmental change as a characteristic of social-ecological systems linked to resilience. Research on vulnerability to the impacts of climate change spans all the antecedent and successor traditions. The challenges for vulnerability research are to develop robust and credible measures, to incorporate diverse methods that include perceptions of risk and vulnerability, and to incorporate governance research on the mechanisms that mediate vulnerability and promote adaptive action and resilience. These challenges are common to the domains of vulnerability, adaptation and resilience and form common ground for consilience and integration.  相似文献

This paper offers insights for assessing organizational resilience to the effects of climate change, specifically to climate and weather extremes. The assessment of organizational resilience to climate and weather extremes brings about several challenges due to (1) uncertainties about future climate change outcomes across temporal and spatial scales and (2) a lack of insight into what lead to organizational resilience, or which variables should be measured in a given study. We suggest methodological pathways for organizational managers to identify properties of future climate and weather extremes and to include them in resilience assessments. We also suggest approaches to identify factors that promote organizational resilience to selected climate and weather extremes. Findings are intended to help managers to understand how organizational resilience to climate and weather extremes can be enhanced.  相似文献

Sudden disruptions, or shocks, to food production can adversely impact access to and trade of food commodities. Seafood is the most traded food commodity and is globally important to human nutrition. The seafood production and trade system is exposed to a variety of disruptions including fishery collapses, natural disasters, oil spills, policy changes, and aquaculture disease outbreaks, aquafeed resource access and price spikes. The patterns and trends of these shocks to fisheries and aquaculture are poorly characterized and this limits the ability to generalize or predict responses to political, economic, and environmental changes. We applied a statistical shock detection approach to historic fisheries and aquaculture data to identify shocks over the period 1976–2011. A complementary case study approach was used to identify possible key social and political dynamics related to these shocks. The lack of a trend in the frequency or magnitude of the identified shocks and the range of identified causes suggest shocks are a common feature of these systems which occur due to a variety, and often multiple and simultaneous, causes. Shocks occurred most frequently in the Caribbean and Central America, the Middle East and North Africa, and South America, while the largest magnitude shocks occurred in Asia, Europe, and Africa. Shocks also occurred more frequently in aquaculture systems than in capture systems, particularly in recent years. In response to shocks, countries tend to increase imports and experience decreases in supply. The specific combination of changes in trade and supply are context specific, which is highlighted through four case studies. Historical examples of shocks considered in this study can inform policy for responding to shocks and identify potential risks and opportunities to build resilience in the global food system.  相似文献

The focus of this study is on how changes in formal and informal institutions have differential impacts across populations in terms of vulnerability of livelihoods to drought, and the unequal processes that shape adaptation to new conditions. Drought vulnerability occurs as a result of exposure and sensitivity to interrelated economic, social, political, and ecological dynamics. There is a need for approaches that can evaluate how the ability to reduce these exposures and sensitivities becomes socially stratified. Building on our understanding of institutional and biophysical constraints in one pastoralist group ranch, we use an approach that draws on quantitative and qualitative data to combine analyses of entitlements, access, and adaptive capacity. We asked how, in a context of changing herding institutions, the ability to adapt to drought and other stressors, is differentiated among actors. We found that herders with higher livestock wealth are more likely to have entitlement sets that include factors that enable access to secure cattle grazing on private wildlife conservation lands, and access to more distant areas with herds of sheep and cattle – two key means of reducing exposure to drought vulnerability, leading to greater coping ability during drought. Those with lower livestock wealth rely disproportionately on illicit, precarious access to external grazing resources. Higher livestock wealth families experienced disproportionately lower sensitivity to drought with smaller losses of cattle, and likely have decreased sensitivity to drought-related market fluctuations, while others are primarily reliant on small stock and/or precarious access pathways. However, rather than naturalize this differential ability as merely increased adaptive capacity for some that are better able to adapt to novel, local conditions, we argue this instead reflects the unequal footing that households find themselves on, in a shifting institutional landscape of structural and relational access constraints and reconfigurations of reciprocity, that are intertwined with interventions by state and non-state actors.  相似文献

《Climate Policy》2002,2(2-3):129-144
Climate change does not yet feature prominently within the environmental or economic policy agendas of developing countries. Yet evidence shows that some of the most adverse effects of climate change will be in developing countries, where populations are most vulnerable and least likely to easily adapt to climate change, and that climate change will affect the potential for development in these countries. Some synergies already exist between climate change policies and the sustainable development agenda in developing countries, such as energy efficiency, renewable energy, transport and sustainable land-use policies. Despite limited attention from policy-makers to date, climate change policies could have significant ancillary benefits for the local environment. The reverse is also true as local and national policies to address congestion, air quality, access to energy services and energy diversity may also limit GHG emissions. Nevertheless there could be significant trade-offs associated with deeper levels of mitigation in some countries, for example where developing countries are dependent on indigenous coal and may be required to switch to cleaner yet more expensive fuels to limit emissions. The distributional impacts of such policies are an important determinant of their feasibility and need to be considered up-front. It follows that future agreements on mitigation and adaptation under the convention will need to recognise the diverse situations of developing countries with respect to their level of economic development, their vulnerability to climate change and their ability to adapt or mitigate. Recognition of how climate change is likely to influence other development priorities may be a first step toward building cost-effective strategies and integrated, institutional capacity in developing countries to respond to climate change. Opportunities may also exist in developing countries to use regional economic organisations to assist in the design of integrated responses and to exploit synergies between climate change and other policies such as those designed to combat desertification and preserve biodiversity.  相似文献

This paper assesses the vulnerability of grape growers and winery operators in the Okanagan Valley, British Columbia to climate variability and change, in the context of other sources of risk. Through interviews and focus groups, producers identified the climatic and non-climatic risks relevant to them and the strategies employed to manage these risks. The results show that the presence of multiple exposures affects the way in which producers are vulnerable to climate change. Producers are vulnerable to conditions that not only affect crop yield, but also affect their ability to compete in or sell to the market. Their sensitivity to these conditions is influenced in part by institutional factors such as trade liberalization and a “markup-free delivery” policy. Producers’ ability to adapt or cope with these risks varies depending on such factors as the availability of resources and technology, and access to government programmes. Producers will likely face challenges associated with the supply of water for irrigation due to a combination of climatic changes and changing demographics in the Okanagan Valley, which in turn affect their ability to adapt to climatic conditions. Finally, adaptations made by producers can change the nature of the operation and its vulnerability, demonstrating the dynamic nature of vulnerability.  相似文献

Africa is thought to be the region most vulnerable to the impacts of climate variability and change. Agriculture plays a dominant role in supporting rural livelihoods and economic growth over most of Africa. Three aspects of the vulnerability of food crop systems to climate change in Africa are discussed: the assessment of the sensitivity of crops to variability in climate, the adaptive capacity of farmers, and the role of institutions in adapting to climate change. The magnitude of projected impacts of climate change on food crops in Africa varies widely among different studies. These differences arise from the variety of climate and crop models used, and the different techniques used to match the scale of climate model output to that needed by crop models. Most studies show a negative impact of climate change on crop productivity in Africa. Farmers have proved highly adaptable in the past to short- and long-term variations in climate and in their environment. Key to the ability of farmers to adapt to climate variability and change will be access to relevant knowledge and information. It is important that governments put in place institutional and macro-economic conditions that support and facilitate adaptation and resilience to climate change at local, national and transnational level.  相似文献

Resource-dependent industries are particularly vulnerable to climate change, and their ability to adapt will be as critical to society as to the natural systems upon which they rely. More than ever, resource-users will need to anticipate, and prepare for, climate-related changes, and institutions will need to be particularly supportive, if resource industries and the extended social systems dependent on them are to be sustained. I examine the capacity of cattle-graziers in Australia to cope and adapt to climate variability as a precursor for understanding their vulnerability to climate change by assessing: (i) their perception of risk, (ii) their capacity to plan, learn and reorganise, (iii) their proximity to the thresholds of coping, and (iv) their level of interest in adapting to change. Graziers perceived themselves to be resilient to climate variability in their perceptions of climate risk, reorganising capacity, coping, and interest in adapting. Their dependency on the grazing resource and use of seasonal climate forecasts were significant influences, suggesting that resilience could be enhanced. Facilitated collaborative learning amongst graziers and other stakeholders may assist to develop strategic skills, increasing climate awareness, developing financial security and adopt climate tools such as seasonal climate forecasts. Enhanced strategies for coping with climate variability will provide a way for encouraging gradual, incremental adjustments for climate adaptation.  相似文献

利用1980-2011年观测的降水和美国NCEP/NCAR大气再分析等资料,采用经验正交分解(EOF)和线性回归等统计方法,讨论了2011年发生在长江中下游地区春夏旱涝急转的成因。结果表明:该年1-5月持续的La Nina事件导致西北太平洋副热带高压位置位于125°E以东,西北太平洋副热带高压西北侧的西南风伴随的水汽通量无法达到长江流域,从而导致了2011年长江流域1-5月份的持续性干旱现象。伴随La Nina的减弱,6月份的青藏高原的感热明显增强,诱发西北太平洋副热带高压自东向西北方向移动到110°E,引导西南风水汽向长江流域输送,而青藏高原对流的加强和向东移动与来自西北太平洋副热带高压西北侧的西南气流在长江中下游地区的汇合导致了6月份长江中下游降水的急剧增加,从而形成了2011年长江中下游地区春夏季节的旱涝急转。  相似文献

The vulnerability of India and Indian states to climate change was assessed using the Vulnerability-Resilience Indicator Prototype (VRIP). The model was adapted from the global/country version to account for Indian dietary practices and data availability with regard to freshwater resources. Results (scaled to world values) show nine Indian states to be moderately resilient to climate change, principally because of low sulfur emissions and a relatively large percentage of unmanaged land. Six states are more vulnerable than India as a whole, attributable largely to sensitivity to sea storm surges. Analyses of results at the state level (Orissa, and comparisons between Maharashtra and Kerala, and Andhra Pradesh and Himachal Pradesh) demonstrate the value of VRIP analyses used in conjunction with other socio-economic information to address initial questions about the sources of vulnerability in particular places. The modeling framework allows analysts and stakeholders to systematically evaluate individual and sets of indicators and to indicate where the likely vulnerabilities are in the area being assessed.  相似文献

Greater recognition of the seriousness of global environmental change has led to an increase in research that assesses the vulnerability of households, communities and regions to changing environmental or economic conditions. So far, however, there has been relatively little attention given to how assessments can be conducted in ways that help build capacity for local communities to understand and find their own solutions to their problems. This paper reports on an approach that was designed and used to work with a local grass roots organization in the Solomon Islands to promote inclusivity and participation in decision-making and to build the capacity of the organization to reduce the vulnerability of communities to drivers of change. The process involved working collaboratively with the organization and training its members to conduct vulnerability assessments with communities using participatory and deliberative methods. To make best use of the learning opportunities provided by the research process, specific periods for formal reflection were incorporated for the three key stakeholders involved: the primary researchers; research assistants; and community members. Overall, the approach: (1) promoted learning about the current situation in Kahua and encouraged deeper analysis of problems; (2) built capacity for communities to manage the challenges they were facing; and (3) fostered local ownership and responsibility for problems and set precedents for future participation in decision-making. While the local organization and the communities it serves still face significant challenges, the research approach set the scene for greater local participation and effort to maintain and enhance livelihoods and wellbeing. The outcomes highlight the need for greater emphasis on embedding participatory approaches in vulnerability assessments for communities to benefit fully from the process.  相似文献

The livelihoods and life chances of pastoral communities in the West African Sahel are linked to: the complexity of the activities they must engage in to insure access to resources; to the nature of conflicts and co-operation between ethnic groups; to the inconsistent role of the state in assisting or constraining pastoral livelihoods; and to the negative discourse surrounding pastoralism that still circulates in some government and development policy circles. The paper reviews pastoral livelihoods systems in eastern Niger to illustrate changing modes of access to water and pasture, culminating in present-day tensions and conflict between pastoral groups. State development efforts to provide secure watering points for pastoral herds have initiated social conflicts and violence, rather than creating security. No viable solution has yet been found to control the use of public wells and boreholes. Enabling frameworks for negotiation and conflict resolution must be developed locally, and centrally enforced in this, and many other regions of uncertain climatic change and overlapping systems of resource exploitation.  相似文献

Climate science to date demonstrates that natural and human systems must urgently adapt. Adaptation refers to changes in societies and ecological systems as they respond to both actual and anticipated impacts of the changing climate. While adaptation is not limited to the level of planning and policy, existing adaptation practice privileges institutional action. We argue that the definition of adaptation should be broadened to include the small, incremental changes made in our daily lives to accommodate the shifting ecologies in which we live. Drawing on critical adaptation research and our own ethnographic fieldwork in the Global South, we define everyday adaptation as the shifted ways a person works, eats, lives and thinks in response to climate realities, rather than the hardening of coastlines or the relocation of vulnerable structures. We integrate and build on existing scholarship on adaptation and the everyday to theorize the logics of everyday, hyperlocal adaptation. This hyperlocal scale is a critical component of any definition of adaptation and a useful lens for studying the way much of the global population adapts and will continue to adapt their lives to climate change. We offer two theoretical components of adaptation revealed by the everyday - adaptation labor and value adaptation – as lenses to see changes in everyday action. Through considering hyperlocal action, we then identify and explore four logics of everyday adaptation actions: lifestyle stability, socio-ecological reactivity, livelihood flexibility, and community capacity. Everyday adaptations are limited by individuals’ capacity to adapt and thereby determine the longevity, livability, and quality of life of places on the frontlines of climate change. We argue for understanding the aggregate effects of everyday adaptation in order to better align the actions of those living with climate change in their everyday lives and the large-scale adaptation projects aiming to protect them.  相似文献

大气环流模式中动力框架与物理过程的相互响应   总被引:4,自引:3,他引:4  
用大气环流模式CAM3.1和IAP AGCM4.0对模式中动力框架与物理过程之间的相互作用及响应关系进行了初步探讨。选用理想的物理过程(Held-Suarez强迫)及完整物理参数化方案,分别对两个模式积分了60 d。试验表明,动力框架与物理过程之间的相互响应在低纬对流层和高纬对流层中上层有着较大的区别。在低纬对流层,动力框架及物理过程产生的温度倾向都有着较大的变率,对总的温度倾向的变率均有较大的贡献,且二者之间为相互补偿的反相关关系;在高纬对流层的中上层,总的温度倾向的变化主要依赖于动力框架的贡献,物理过程造成的倾向变化很缓慢,可近似地看做定常的强迫,且物理过程产生的温度倾向与动力框架产生的温度倾向之间为正位相的响应关系。此外,还对各个物理参数化方案之间的相互作用及响应关系进行了分析。结果表明,在所有过程中,湿过程所引起的温度倾向的变化最为显著,对总的物理过程倾向的贡献也最大;在高纬地区,长波辐射冷却也有较大的变率;短波辐射加热率及垂直扩散加热率的变化相对较小;长波辐射冷却和短波辐射加热之间为近似负反馈的响应关系。  相似文献
