TL;DR: In this article, the authors present a methodology for investigating regional vulnerability to climate change in combination with other global stressors, which relies on both vulnerability mapping and local-level case studies, and can serve as a basis for targeting policy interventions.
Abstract: There is growing recognition in the human dimensions research community that climate change impact studies must take into account the effects of other ongoing global changes. Yet there has been no systematic methodology to study climate change vulnerability in the context of multiple stressors. Using the example of Indian agriculture, this paper presents a methodology for investigating regional vulnerability to climate change in combination with other global stressors. This method, which relies on both vulnerability mapping and local-level case studies, may be used to assess differential vulnerability for any particular sector within a nation or region, and it can serve as a basis for targeting policy interventions.

TL;DR: It is suggested that psychosocial stress may be the vulnerability factor that links social conditions with environmental hazards, and that residential segregation leads to differential experiences of community stress, exposure to pollutants, and access to community resources.
Abstract: Although it is often acknowledged that social and environmental factors interact to produce racial and ethnic environmental health disparities, it is still unclear how this occurs. Despite continued controversy, the environmental justice movement has provided some insight by suggesting that disadvantaged communities face greater likelihood of exposure to ambient hazards. The exposure‐ disease paradigm has long suggested that differential “vulnerability” may modify the effects of toxicants on biological systems. However, relatively little work has been done to specify whether racial and ethnic minorities may have greater vulnerability than do majority populations and, further, what these vulnerabilities may be. We suggest that psychosocial stress may be the vulnerability factor that links social conditions with environmental hazards. Psychosocial stress can lead to acute and chronic changes in the functioning of body systems (e.g., immune) and also lead directly to illness. In this article we present a multidisciplinary framework integrating these ideas. We also argue that residential segregation leads to differential experiences of community stress, exposure to pollutants, and access to community resources. When not counterbalanced by resources, stressors may lead to
TL;DR: Impacts on vector-borne diseases, including malaria, dengue fever, infections by other arboviruses, schistosomiasis, trypanosomosis, onchocerciasis, and leishmaniasis are reviewed.
Abstract: Global change includes climate change and climate variability, land use, water storage and irrigation, human population growth and urbanization, trade and travel, and chemical pollution. Impacts on vector-borne diseases, including malaria, dengue fever, infections by other arboviruses, schistosomiasis, trypanosomiasis, onchocerciasis, and leishmaniasis are reviewed. While climate change is global in nature and poses unknown future risks to humans and natural ecosystems, other local changes are occurring more rapidly on a global scale and are having significant effects on vector-borne diseases. History is invaluable as a pointer to future risks, but direct extrapolation is no longer possible because the climate is changing. Researchers are therefore embracing computer simulation models and global change scenarios to explore the risks. Credible ranking of the extent to which different vector-borne diseases will be affected awaits a rigorous analysis. Adaptation to the changes is threatened by the ongoing loss of drugs and pesticides due to the selection of resistant strains of pathogens and vectors. The vulnerability of communities to the changes in impacts depends on their adaptive capacity, which requires both appropriate technology and responsive public health systems. The availability of resources in turn depends on social stability, economic wealth, and priority allocation of resources to public health.

TL;DR: The case for the robust associations between measures of adverse psychosocial environment and ill health is advanced, as they are based on comparative studies across several European countries and as they combine different types of study designs.
TL;DR: In this paper, the authors examined the short and long-term economic, and financial impacts of natural disasters, and made recommendations for future research, and cooperation, where appropriate, recommendations are made.
Abstract: The study described here examines the short- and long-term economic, and financial impacts of natural disasters. It relies in part, on in-depth case studies of overall sensitivity to natural hazards in the small island economy of Dominica; public finance consequences of disasters in Bangladesh; and, the economic consequences of climatic variability, and the use of climatic forecasting in Malawi and southern Africa. Policy implications are drawn, and, where appropriate, recommendations are made. Finally, directions for future research, and cooperation are outlined. Major natural disasters can, and do have severe negativeshort-run economic impacts, and also appear to have adverse longer-term consequences for economic growth, development, and poverty reduction. But negative impacts are not inevitable. A full reassessment of the economic, and financial impacts of a major disaster, should be made 18 to 24 months after the event. It should be taken into account in reviewing the affected country's short-term economic performance, and the assistance strategy for the country. Vulnerability to natural hazards is determined by a complex, dynamic set of influences that include the country's economic structure, stage of development, and prevailing economic and policy conditions. The eclectic approach adopted in this study, which employed largely qualitative methods, is particularly useful in exploring the many complex, and dynamic pathways through which extreme hazard events influence an economy, and its financial system, as well as for identifying areas, and issues where further investigation, including quantification, would be worthwhile.
TL;DR: Vulnerability is one of the least examined concepts in research ethics as discussed by the authors, and it has lost its power in the context of research, particularly international research, that many groups are now considered to be vulnerable.
Abstract: Vulnerability is one of the least examined concepts in research ethics. Vulnerability was linked in the Belmont Report to questions of justice in the selection of subjects. Regulations and policy documents regarding the ethical conduct of research have focused on vulnerability in terms of limitations of the capacity to provide informed consent. Other interpretations of vulnerability have emphasized unequal power relationships between politically and economically disadvantaged groups and investigators or sponsors. So many groups are now considered to be vulnerable in the context of research, particularly international research, that the concept has lost force. In addition, classifying groups as vulnerable not only stereotypes them, but also may not reliably protect many individuals from harm. Certain individuals require ongoing protections of the kind already established in law and regulation, but attention must also be focused on characteristics of the research protocol and environment that present ethical challenges.
TL;DR: In this paper, a multi-scale assessment of climate change impacts and vulnerability in Norway is presented, and it is shown that the concept of vulnerability depends on the scale of analysis.
Abstract: This paper explores the issue of climate vulnerability in Norway, an affluent country that is generally considered to be resilient to the impacts of climate change. In presenting a multi-scale assessment of climate change impacts and vulnerability in Norway, we show that the concept of vulnerability depends on the scale of analysis. Both exposure and the distribution of climate sensitive sectors vary greatly across scale. So do the underlying social and economic conditions that influence adaptive capacity. These findings question the common notion that climate change may be beneficial for Norway, and that the country can readily adapt to climate change. As scale differences are brought into consideration, vulnerability emerges within some regions, localities, and social groups. To cope with actual and potential changes in climate and climate variability, it will be necessary to acknowledge climate vulnerabilities at the regional and local levels, and to address them accordingly. This multi-scale assessment of impacts and vulnerability in Norway reinforces the importance of scale in global change research.
TL;DR: In this paper, the authors discuss the concept of vulnerability as characterized in the climate change literature and present a framework for assessing adaptive capacity of coastal communities to climate change related risks, highlighting determinants of adaptive capacity at the local scale and situates them within larger regional, national and international settings.
Abstract: DOLAN, A.H., and WALKER, I.J., 2003. Understanding vulnerability of coastal communities to climate change related risks. Journal of Coastal Research, SI 39 (Proceedings of the 8th International Coastal Symposium), pg – pg. Itajai, SC – Brazil, ISSN 0749-0208 This paper discusses the concept of vulnerability as characterized in the climate change literature and presents a framework for assessing adaptive capacity. The framework recognizes inherent susceptibilities of humanenvironment systems exposed to climate variability and change. As climate change impacts are unevenly distributed among and within nations, regions, communities and individuals due to differential exposures and vulnerabilities, the framework highlights determinants of adaptive capacity at the local scale and situates them within larger regional, national and international settings. Determinants include: access and distribution of resources, technology, information and wealth; risk perceptions; social capital and community structure; and institutional frameworks that address climate change hazards. This broader approach contrasts typical impact assessments that focus largely on reducing economic detriments of change. The framework provides a methodological starting point that, as a community-based or ‘bottom-up’ approach, yields important insight on local responses to climate change. It also recognizes that short-term exposure to variability is an important source of vulnerability superimposed on long-term change. At the community level, perceptions and experiences with climate extremes can identify inherent characteristics that enable or constrain a community to respond, recover and adapt. As such, local and traditional knowledge is key to climate change research and should be incorporated into research design and implementation. This approach provides locally relevant outcomes that could promote more effective decision-making, planning and management in remote areas susceptible to climate change hazards. As part of a larger study, this approach will be refined with local input to study sea-level rise impacts on one of Canada’s most sensitive coastlines, northeast Graham Island, Haida Gwaii (Queen Charlotte Islands), British Columbia. Preliminary evidence of changes and responses in this area are identified as a brief case study.
TL;DR: In this paper, a broad range of evidence detailing factors at individual, household, and community levels that influence vulnerability to malaria, tuberculosis, and HIV infection was reviewed and used to identify strategies that could improve resilience to these diseases.
Abstract: A high burden of malaria, tuberculosis, and HIV infection contributes to national and individual poverty. We have reviewed a broad range of evidence detailing factors at individual, household, and community levels that influence vulnerability to malaria, tuberculosis, and HIV infection and used this evidence to identify strategies that could improve resilience to these diseases. This first part of the review explores the concept of vulnerability to infectious diseases and examines how age, sex, and genetics can influence the biological response to malaria, tuberculosis, and HIV infection. We highlight factors that influence processes such as poverty, livelihoods, gender discrepancies, and knowledge acquisition and provide examples of how approaches to altering these processes may have a simultaneous effect on all three diseases.
TL;DR: The authors conclude that Blatt's and Beck's concepts are continuous, nearly orthogonal dimensions that can be identified and measured independently from Neuroticism, depression, and social context.
Abstract: J. C. Coyne and V. E. Whiffen (1995) reviewed research on personality vulnerability to depression, focusing on S. J. Blatt's (1974, 1990) concepts of dependency and self-criticism and A. T. Beck's (1983) concepts of sociotropy and autonomy. The authors discuss 6 issues raised in that review: (a) the typological or dimensional nature of vulnerability, (b) the theoretical implications of "mixed" vulnerability, (c) the relations of vulnerability to Neuroticism. (d) the potential confounding of vulnerability with concurrent depression, (e) the potential confounding of vulnerability with social context, and (f) the differentiation of dependency from relatedness. The authors conclude that Blatt's and Beck's concepts are continuous, nearly orthogonal dimensions that can be identified and measured independently from Neuroticism, depression, and social context.
TL;DR: In this article, the authors introduce a Gini coefficient for climate change impacts, which shows the distribution of impacts is very skewed in the near future and will deteriorate for more than a century before becoming more egalitarian.
Abstract: Climate change is likely to impact more severely on the poorer people of the world, because they are more exposed to the weather, because they are closer to the biophysical and experience limits of climate, and because their adaptive capacity is lower. Estimates of aggregated impacts necessarily make assumptions on the relative importance of sectors, countries and periods; we propose to make these assumption explicit. We introduce a Gini coefficient for climate change impacts, which shows the distribution of impacts is very skewed in the near future and will deteriorate for more than a century before becoming more egalitarian. Vulnerability to climate change depends on more than per capita income alone, so that the geographical pattern of vulnerability is complex, and the relationship between vulnerability and development non-linear and non-monotonous.
TL;DR: The report Climate Change Impacts and Adaptation: A Canadian Perspective as mentioned in this paper provides an overview of research in the field of climate change impacts and adaptation over the past five years, as it relates to Canada.
Abstract: There is strong consensus in the international scientific community that climate change is occurring and that the impacts are already being felt in some regions. It is also widely accepted that, even after introducing significant measures to reduce greenhouse gas emissions, some additional degree of climate change is inevitable and would have economic, social and environmental impacts on Canada and Canadian communities. Although impacts would vary on a regional basis, all areas of the country and virtually every economic sector would be affected. To reduce the negative impacts of climate change and take advantage of new opportunities, Canadians will adapt. Adaptation is not an alternative to reducing greenhouse gas emissions in addressing climate change, but rather a necessary complement. Reducing greenhouse gas emissions decreases both the rate and overall magnitude of climate change, which increases the likelihood of successful adaptation and decreases associated costs. Adaptation is not a new concept: Canadians have already developed a range of approaches that have allowed us to deal effectively with our extremely variable climate. Nevertheless, the nature of future climate change, as well as its rate, would pose some new challenges. Developing an effective strategy for adaptation requires an understanding of our vulnerability to climate change. Vulnerability is determined by three factors: the nature of climate change, the climatic sensitivity of the system or region being considered, and our capacity to adapt to the resulting changes. The tremendous geographic, ecological and economic diversity of Canada means that these factors, and hence vulnerabilities, vary significantly across the country. In many cases, adaptation will involve enhancing the resiliency and adaptive capacity of a system to increase its ability to deal with stress. The report Climate Change Impacts and Adaptation: A Canadian Perspective provides an overview of research in the field of climate change impacts and adaptation over the past five years, as it relates to Canada. This summary presents common themes of the report, as well as highlights from individual chapters.
TL;DR: In this article, a methodology to assess household vulnerability using pseudo panel data derived from repeated cross-sections augmented with historical information on shocks is presented, where interventions directed at reducing the incidence of malaria, promoting adult literacy, and improving market accessibility hold most promise to reduce vulnerability.
Abstract: Considerations of risk and vulnerability are key to understanding the dynamics of poverty. This study conceives vulnerability as expected poverty and illustrates a methodology to empirically assess household vulnerability using pseudo panel data derived from repeated cross sections augmented with historical information on shocks. Application of the methodology to data from rural Kenya shows that in 1994 rural households faced on average a 40 percent chance of becoming poor in the future. Households in arid areas that experience large rainfall volatility appear more vulnerable than those in non-arid areas, where malaria emerges as a key risk factor. Idiosyncratic shocks also cause non-negligible consumption volatility. Possession of cattle and sheep/goats appears ineffective in protecting consumption against covariant shocks, though sheep/goat help reduce the effect of idiosyncratic shocks, especially in arid zones. Of the policy instruments simulated, interventions directed at reducing the incidence of malaria, promoting adult literacy, and improving market accessibility hold most promise to reduce vulnerability.
TL;DR: In this article, the authors developed a method for spatial, Geographic Information Systems-based assessment of agricultural drought vulnerability in the state of Nebraska, and classified the vulnerability of agricultural crops into low, low-to-moderate, moderate, and high.
Abstract: One of main aspects of drought mitigation and planning is the assessment of who and what is vulnerable and why. The objective of this study was to develop a method for spatial, Geographic Information Systems-based assessment of agricultural drought vulnerability in the state of Nebraska. It was hypothesized that the key biophysical and social factors that define agricultural drought vulnerability were climate, soils, land use, and access to irrigation. The framework for derivation of an agricultural drought vulnerability map was created through development of a numerical weighting scheme to evaluate the drought potential of the classes within each factor. The contribution of the factors was considered to be equal. Nebraska's agricultural drought vulnerability, presented in a map form, was classified in the following categories: low, lowto-moderate, moderate, and high. The identification of agricultural drought vulnerability can be a step towards mitigationoriented drought management and aid in reducing the impacts associated with drought.
TL;DR: Indices of environmental injustice and social vulnerability were developed as part of a U.S. National Risk Survey and it was found that those who regarded themselves as vulnerable and supported belief statements consistent with the environmental justice thesis offered higher risk ratings across a range of hazards.
Abstract: Recent research finds that perceived risk is closely associated with race and gender. In surveys of the American public a subset of white males stand out for their uniformly low perceptions of environmental health risks, while most nonwhite and nonmale respondents reveal higher perceived risk. Such findings have been attributed to the advantageous position of white males in American social life. This article explores the linked possibility that this demographic pattern is driven not simply by the social advantages or disadvantages embodied in race or gender, but by the subjective experience of vulnerability and by sociopolitical evaluations pertaining to environmental injustice. Indices of environmental (in)justice and social vulnerability were developed as part of a U.S. National Risk Survey (n = 1,192) in order to examine their effect on perceived risk. It was found that those who regarded themselves as vulnerable and supported belief statements consistent with the environmental justice thesis offered higher risk ratings across a range of hazards. Multivariate analysis indicates that our measures of vulnerability and environmental (in)justice predict perceived risk but do not account for all of the effects of race and gender. The article closes with a discussion of the implications of these findings for further work on vulnerability and risk, risk communication, and risk management practices generally.
TL;DR: The findings of the research reveal that displacees experience substantial socio-economic impoverishment and marginalisation as a consequence of involuntary migration.
Abstract: The purpose of this research was to identify and analyse patterns of economic and social adaptation among river-bank erosion-induced displacees in Bangladesh. It was hypothesised that the role of social demographic and socio-economic variables in determining the coping ability and recovery of the river-bank erosion-induced displacees is quite significant. The findings of the research reveal that displacees experience substantial socio-economic impoverishment and marginalisation as a consequence of involuntary migration. This in part is a socially constructed process, reflecting inequitable access to land and other resources. Vulnerability to disasters is further heightened by a number of identifiable social and demographic factors including gender, education and age, although extreme poverty and marginalisation create complexity to isolate the relative influence of these variables. The need to integrate hazard analysis and mitigation with the broader economic and social context is discussed. It is argued that the capacity of people to respond to environmental threats is a function of not only the physical forces which affect them, but also of underlying economic and social relationships which increase human vulnerability to risk. Hazard analysis and mitigation can be more effective when it takes into account such social and demographic and socio-economic dimensions of disasters.
TL;DR: In this paper, a system and method for a vulnerability assessment mechanism that serves to actively scan for vulnerabilities on a continuous basis and interpret the resulting traffic in context of policy is provided.
Abstract: A system and method for a vulnerability assessment mechanism that serves to actively scan for vulnerabilities on a continuous basis and interpret the resulting traffic in context of policy is provided. Vulnerability information is presented within an enterprise manager system enabling the user to access vulnerability information, recommended remediation procedures, and associated network traffic. A studio mechanism is used to add scanners to the appropriate policies and control the scope and distribution of scans within the target network.
TL;DR: In this paper, a simplified, flexible framework for conducting a drought risk analysis is presented, based on a combination of natural hazards theory and interactions with a variety of drought planners in the field.
Abstract: Drought events across the United States since 1995 illustrate the country’s continuing vulnerability to drought. Officials are beginning to recognize the need for enhanced mitigation actions to reduce the increasing economic, environmental, and social impacts of droughts. One way to better understand a region’s drought vulnerability and identify the appropriate mitigation actions to take is to conduct a drought risk analysis. However, drought risk can be a confusing concept for many planners. For this reason, a simplified, flexible framework for conducting a drought risk analysis is presented. This framework is based on a combination of natural hazards theory and interactions with a variety of drought planners in the field, and is intended to be a practical, action-oriented model to assist drought planners on a variety of political and geographic scales. Several case studies are also discussed to demonstrate the application of such a model.
TL;DR: In this paper, the authors present a map of the landscape of vulnerability, revealing the lie of the land and the shape of its contours, and propose a set of possible paths to traverse it.
Abstract: What makes people vulnerable? To most people today, this is an everyday question
that is as simple as it is complex. At one level, the answer is a straightforward one
about poverty, resource depletion and marginalization; at another level, it is about
the diversity of risks generated by the interplay between local and global processes
and coping with them on a daily basis. For billions of people, the nature of their
vulnerability is changing and intensifying, while their ability to cope has
diminished. The saddest part, perhaps, is the loss of hope for the future. As James
Ferguson so eloquently pleads, the current construction of a new world order not
only continues to exclude large numbers of people, but actually robs them of
even the promise of development (Ferguson, 1999, pp237-8). Living with the
poverty and uncertainty of their daily existence severely constrains their freedom
of choice and leaves them prey to a creeping despair that the magnitude and
frequency of natural and human-induced disasters only make worse. This book is
an opportunity for a group of scholars and practitioners to grapple with the
simple-complex paradox so manifest in the nature of vulnerability. Each
contributes a different perspective to the problem, all seeking in some way to
resolve the apparent contradiction of reconciling local experiences with global
considerations. The nature of this complexity dictates that there can be no general
theory and therefore no simple solutions. What we offer instead is a map. It
delineates the landscape of vulnerability, revealing the lie of the land and the
shape of its contours. While there are many possible paths on this map, there are,
however, no set routes or even fixed destinations.
TL;DR: The authors investigated linkages among the degree of consumption insurance, households' vulnerability to poverty, and household use of formal and informal coping mechanisms using the same empirical approach in five different countries.
Abstract: This paper brings together some of the empirical work conducted by IFPRI researchers which investigates linkages among the degree of consumption insurance, households'vulnerability to poverty, and household use of formal and informal coping mechanisms using the same empirical approach in five different countries.
TL;DR: In this article, a security information management system is described, wherein client-side devices preferably collect and monitor information describing the operating system, software, and patches installed on the device(s), as well as configuration thereof.
Abstract: of the Disclosure A security information management system is described, wherein client-side devices preferably collect and monitor information describing the operating system, software, and patches installed on the device(s), as well as configuration thereof. A database of this information is maintained, along with data describing vulnerabilities of available software and associated remediation techniques available for it. The remediation techniques in the database include some that apply software patches, some that change the device’s policy settings, and some that change one of the device’s configuration files or registry.
TL;DR: In this paper, a market response model for the frozen pizza category was developed to cope with the challenges dynamic environments entail: nonstationarity, changes in parameters over time, missing data and cross-sectional heterogeneity.
Abstract: Product innovation is endemic among consumer packaged goods firms, and is an integral component of their marketing strategy. As innovations impact markets, there is a pressing need to develop market response models that can adapt to such changes. Our model copes with the challenges dynamic environments entail: nonstationarity, changes in parameters over time, missing data, and cross-sectional heterogeneity. We use this approach to model sales response in the frozen pizza category, in which the introduction of rising crust pizza brands represented a major innovation. The model is directly applicable to other domains in which market structure might be non-stationary: changes in promotion strategy, shifts in the retail environment, movements in macro-economic factors, etc. In our application, we find that innovation i) makes the existing brands appear more similar, as indicated by increasing cross-brand price elasticities, ii) decreases brand differentiation for the existing brands as indicated by an increase in the magnitude of own-brand price elasticities and iii) increases the variance of the sales response equations temporarily around the time of the introduction of the innovation, indicating increased uncertainty in sales response. The adjustment of the market to the innovations takes about seven weeks. We conclude by discussing the managerial implications by i) presenting maps of how clout and vulnerability evolve over time, ii) assessing the effect of new brands on cannibalization and iii) considering the strategic implications of introducing a flanker innovation to facilitate the ability of an extant brand to attack an extant incumbent leader.
TL;DR: Wang et al. as discussed by the authors proposed a data envelopment analysis (DEA)-based model for analysis of regional vulnerability to natural disasters to improve upon the traditional method, which is sensitive to the weights selected for sub-indices when multi-indexes are added up to get an index of total vulnerability.
TL;DR: This paper addresses how case analysis findings can be used in decision making to promote non-adverse interdependency-related outcomes from extreme events.
Abstract: Interdependencies among critical infrastructure systems are well recognized as key points of vulnerability that can compromise system performance especially during extreme events. At the heart of these vulnerabilities are decisions, often unnoticed and indirect, which occur anywhere from infrastructure planning, siting and design through operation and maintenance. The key contributions of the paper are (i) the presentation of a method for constructing a catalog of infrastructure interdependences, (ii) the construction of a set of indicators transferable to other databases, and (iii) preliminary analytical results of the application of the indicators to a sample database of catalogued events with inter dependencies. This paper addresses how case analysis findings can be used in decision making to promote non-adverse interdependency-related outcomes from extreme events. Critical infrastructure analyzed includes facilities and services for transportation, telecommunications, water supply, wastewater, electric power and other energy infrastructure. Event databases for this research include government, industry, academic and media reports
TL;DR: A therapeutic approach for deconstructing couples' impasses and facilitating new patterns through deliberate modes of questioning, a freeze-frame technique, stimulation of calmness and reflection, separating present from past, and elicitation of alternative meanings, behaviors, empathy, and choice is suggested.
Abstract: In this article, we propose the vulnerability cycle as a construct for understanding and working with couples' impasses. We expand the interactional concept of couples' reciprocal patterns to include behavioral and subjective dimensions, and articulate specific processes that trigger and maintain couples' entanglements. We consider the vulnerability cycle as a nexus of integration in which "vulnerabilities" and "survival positions" are key ideas that bring together interactional, sociocultural, intrapsychic, and intergenerational levels of meaning and process. The vulnerability cycle diagram is presented as a tool for organizing information. We suggest a therapeutic approach for deconstructing couples' impasses and facilitating new patterns through deliberate modes of questioning, a freeze-frame technique, stimulation of calmness and reflection, separating present from past, and elicitation of alternative meanings, behaviors, empathy, and choice. This approach encourages the therapist and couple to work collaboratively in promoting change and resilience.
TL;DR: This paper developed economic measures of vulnerability to climate change with and without adaptation in agricultural production systems using coupled, site-specific ecosystem and economic simulation models, and applied this approach to the dryland grain production systems of the Northern Plains region of the United States.
Abstract: In this paper we develop economic measures of vulnerability to climate change with and without adaptation in agricultural production systems. We implement these measures using coupled, site-specific ecosystem and economic simulation models. This modeling approach has two key features needed to study the response of agricultural production systems to climate change: it represents adaptation as an endogenous, non-marginal economic response to climate change; and it provides the capability to represent the spatial variability in bio-physical and economic conditions that interact with adaptive responses. We apply this approach to the dryland grain production systems of the Northern Plains region of the United States. The results support the hypothesis that the most adverse impacts on net returns distributions tend to occur in the areas with the poorest resource endowments and when mitigating effects of CO2 fertilization and adaptation are absent. We find that relative and absolute measures of vulnerability depend on complex interactions between climate change, CO2 level, adaptation, and economic conditions such as relativeoutput prices. The relationship between relative vulnerability and resource endowments varies with assumptions about climate change, adaptation, and economic conditions. Vulnerability measured with respect to an absolute threshold is inversely related to resource endowments in all cases investigated.
