A CHOICE-EXPERIMENT BASED ANALYSIS OF PROTECTION MOTIVATION THEORY: HEALTH RELATED BEHAVIOR OF CONSUMERS WITH CELIAC DISEASE AgEcon
Zhang, Jing; Steiner, Bodo E..
The underlying components of protection motivation theory (PMT; Rogers 1983) are explored through choice experiment-based analysis within a random utility framework, to account for some of the motivational, cognitive, and affective processes that likely affect celiacs’ propensity to use a novel health-risk reducing product. Those four groups of variables that are aimed to capture threat appraisal and coping appraisal processes as part of the standard PMT (Rogers 1975, 1983; Floyd et al. 2000) are found to contribute significantly to explaining the adaptive response of celiacs. Self-assessed vulnerability and perceived product efficacy form a most significant part of respondents’ threat appraisal process. Standard socio-demographic and lifestyle...

A mezőgazdasági területek érzékenységének és adaptációs képességének mérési lehetőségei AgEcon
Farkas-Fekete, Maria.
A tanulmány alapvető célja az, hogy hozzájáruljon az érzékenység, sérülékenység és adaptációs képesség vizsgálatának módszertanához. A kutatások eredményei felhívják a figyelmet arra, hogy bár az európai vidék összessége egyre sérülékenyebbé válik a különböző globális kihívásokra, a veszélyeztetettség mértéke régiónként eltérő. A kutatások eredményei megerősítették az IPCC 3. jelentésében megfogalmazott hipotéziseket, melyek szerint a gazdag országok ugyanolyan veszélyeztetettség mellett is kevésbé sérülékenyek, mivel nagyobb az alkalmazkodóképességük. A klímaváltozás, amely pozitív és negatív hatást is gyakorol Európa mezőgazdaságára, módosítja az eddigi komparatív előnyöket, illetve hátrányokat. Gazdasági szempontból Dél- és Közép-Kelet-Európa minden...

A Typology for Vulnerability and Agriculture in Sub-Saharan Africa AgEcon
Zhang, Xiaobo; Rockmore, Marc; Chamberlin, Jordan.
This paper considers vulnerability reduction in Sub-Saharan Africa (SSA) from a more aggregated macro viewpoint. We focus on risk related to agriculture, since vulnerability and agriculture are intimately linked in SSA due to the location of the poor, their dependence on agriculture and the inherent risks of an agricultural livelihood. We argue that agricultural growth is one of the most effective means for improving permanent incomes and reducing vulnerability. However, agriculture is not homogeneous, and the inherent risks vary across countries and regions. Therefore, we also discuss appropriate investment strategies and policy instruments for different sets of risks.

Access and Resilience: Analyzing the Construction of Social Resilience to the Threat of Water Scarcity Ecology and Society
Langridge, Ruth; University of California, Santa Cruz; rlangrid@ucsc.edu; Christian-Smith, Juliet; University of California, Berkeley; jchristi2001@gmail.com; Lohse, Kathleen A.; Global Institute of Sustainability, Arizona State University; Kathleen.Lohse@asu.edu.
Resilience is a vital attribute that characterizes a system’s capacity to cope with stress. Researchers have examined the measurement of resilience in ecosystems and in social–ecological systems, and the comparative vulnerability of social groups. Our paper refocuses attention on the processes and relations that create social resilience. Our central proposition is that the creation of social resilience is linked to a community’s ability to access critical resources. We explore this proposition through an analysis of how community resilience to the stress of water scarcity is influenced by historically contingent mechanisms to gain, control, and maintain access to water. Access is defined broadly as the ability of a community...

Adaptation to Climate Change in the Developing World OceanDocs
Huq, S.; Adger, W.N.; Brown, K.; Hulme, M..
The world’s climate is changing and will continue to change into the coming century at rates projected to be unprecedented in recent human history. The risks associated with these changes are real but highly uncertain. Societal vulnerability to the risks associated with climate change may exacerbate ongoing social and economic challenges, particularly for those parts of societies dependent on resources that are sensitive to changes in climate. Risks are apparent in agriculture, fisheries and many other components that constitute the livelihood of rural populations in developing countries. In this paper we explore the nature of risk and vulnerability in the context of climate change and review the evidence on present-day adaptation in developing countries...

Alteración de la fertilidad del suelo atribuible al cambio climático y su impacto sobre la productividad de café en el Estado de Veracruz, México. Colegio de Postgraduados
Brigido Morales, Juan Gabriel.
Todas las investigaciones sobre el cambio climático global indican que éste se ve fortalecido con el incremento en la concentración de gases, principalmente CO2. También se ha encontrado que este incremento pueden intensificar las condiciones climáticas medias normales dentro de las que históricamente se ha dado el desarrollo de la agricultura por lo que ésta se vuelve vulnerable, siendo afectada su productividad. El objetivo principal del presente trabajo fue estimar el papel de la posible modificación del índice de fertilidad del suelo debido al cambio climático en los cálculos de la productividad del cultivo de café (Coffea arabica L.) para 20 municipios cafetaleros del estado de Veracruz utilizando 3 escenarios de cambio climático para México...

Alteración de la fertilidad del suelo por el cambio climático su efecto en la productividad de maíz y trigo bajo riego Colegio de Postgraduados
Herrera Gómez, Sergio Santiago.
Se ha desarrollado la metodología de estimación de alteración de algunas propiedades y un índice integral de fertilidad de los suelos irrigados de México atribuible al cambio climático global durante el siglo XXI. Esta metodología fue aplicada para evaluar la vulnerabilidad de la productividad de los cultivos de maíz de grano y trigo bajo riego en algunos distritos de riego de referencia del país ubicados en diferentes zonas climáticas. Los resultados de la investigación señalan que la sensibilidad de los suelos agrícolas bajo riego en México, al cambio climático, es mucho menor que los suelos de temporal y vírgenes y no afecta significativamente la vulnerabilidad de los cultivos de maíz y trigo bajo riego. Por lo general, los valores de cambio de...

An Economic Valuation of Pollination Services in Georgia AgEcon
Barfield, Ashley; Bergstrom, John C.; Ferreira, Susana.
The production of many crops depends on biotic pollination. As pollinator populations decline, assessments of the potential consequential loss of economic value are critical. We estimate the economic value of pollination services ($608 million), crop vulnerability ratio (21 percent), and pollination’s contribution to agricultural production value (5 percent) for Georgia.

AN EMPIRICAL STUDY OF CLIMATE CHANGE EFFECTS AND AGRICULTURE VULNERABILITY AgEcon
Singh, Mahesh Kumar; Dobo, Erika.
This review describes that due to rapid globalization, vulnerability in different areas affects human life. With rapid population growth, securing the inherent vulnerability of this relationship, whether social, economic, or environmental, has to be central to efforts to achieving sustainable development. The vulnerability of agricultural systems varies with geographic location, time, socioeconomic conditions, and environmental resources. The capacity to mitigate and to adapt to climate-change impacts is strongly related to the future development paths. The socioeconomic and, even more so, the technological characteristics of different futures strongly affect emissions, hence the extent and pace of the impacts of climate change, as well as the capability...

An Update on the Scholarly Networks on Resilience, Vulnerability, and Adaptation within the Human Dimensions of Global Environmental Change Ecology and Society
Janssen, Marco A; Arizona State University; Marco.Janssen@asu.edu.
In Janssen et al. (2006), we presented a bibliometric analysis of the resilience, vulnerability, and adaptation knowledge domains within the research activities on human dimensions of global environmental change. We have updated the analysis because 2 years have gone by since the original analysis, and 1113 more publications can now be added to the database. We analyzed how the resulting 3399 publications between 1967 and 2007 are related in terms of co-authorship and citations. The rapid increase in the number of publications in the three knowledge domains continued over the last 2 years, and we still see an overlap between the knowledge domains. We were also able to identify the “hot” publications of the last 2 years.

Application of Structured Decision Making to an Assessment of Climate Change Vulnerabilities and Adaptation Options for Sustainable Forest Management Ecology and Society
Ogden, Aynslie E; Faculty of Forestry, University of British Columbia; Forest Management Branch, Government of Yukon; aynslie.ogden@gov.yk.ca; Innes, John L; Faculty of Forestry, University of British Columbia; john.innes@ubc.ca.
A logical starting point for climate change adaptation in the forest sector is to proactively identify management practices and policies that have a higher likelihood of achieving management objectives across a wide range of potential climate futures. This should be followed by implementation of these options and monitoring their success in achieving management objectives within an adaptive management context. Here, we implement an approach to identify locally appropriate adaptation options by tapping into the experiential knowledge base of local forest practitioners while at the same time, building capacity within this community to implement the results. We engaged 30 forest practitioners who are involved with the implementation of a regional forest...

ASSESSING THE IMPACT OF HIGH-YIELDING VARIETIES OF MAIZE IN RESETTLEMENT AREAS OF ZIMBABWE AgEcon
Bourdillon, Michael; Hebinck, Paul; Hoddinott, John; Kinsey, Bill; Marondo, John; Mudege, Netsayi; Owens, Trudy.
This study is part of a larger effort to explore the impact of agricultural research on poverty reduction. It examines the diffusion and impact of hybrid maize in selected resettlement areas of rural Zimbabwe, paying particular attention to varieties made widely available from the mid-1990s onwards. While “Zimbabwe’s Green Revolution” of the early 1980s was characterized by the widespread adoption of hybrid maize varieties and significant increases in yields, the subsequent diffusion of newer varieties occurred more slowly and had a more modest impact. Several factors account for this. Government now plays a much-reduced role and one that increasingly focuses on “better farmers.” Private-sector institutions that have entered the maize sector operate mainly...

Climate change and poverty in Africa: Mapping hotspots of vulnerability AgEcon
Thornton, Philip K.; Jones, Peter G.; Owiyo, Tom; Kruska, Russell L.; Herrero, Mario; Orindi, Victor; Bhadwal, Suruchi; Kristjanson, Patricia; Notenbaert, An; Bekele, Nigat; Omolo, Abisalom.
Climate change and increasing climate variability threaten the attainment of the Millennium Development Goals (MDG), and some of the worst effects on human health and agriculture will be in sub-Saharan Africa, particularly in vulnerable regions. The relationships between climate change and the vulnerability of resource-poor croppers and livestock keepers and their resilience to current and future climate variability need to be better understood. This paper describes the generation of information that combines projected climate change in agricultural systems with vulnerability data. The results of the analysis, in terms of vulnerable people particularly at risk for deleterious effects of climate change, are being used for impact assessment, targeting and...

Coastal vulnerability, resilience and adaptation to climate change OceanDocs
Klein, R.J..
The work presented in this PhD thesis has not been carried out within a single, well-defined project. Instead, it integrates the results of a number of studies conducted from 1994 onwards, each of which had different clients and objectives. The common theme of the studies has been the description and analysis of elements that determine how coastal systems and communities would and could respond to climate change and, in particular, how this response may be assessed as part of coastal vulnerability studies. Coastal zones are amongst the most dynamic natural environments on earth, providing a range of goods and services that are essential to human social and economic well-being. Coastal zones represent the narrow transitional zone between the world’s land...

Collective Action and Property Rights for Poverty Reduction: A Review of Methods and Approaches AgEcon
Mwangi, Esther; Markelova, Helen.
While much attention has been given to examining various aspects of poverty, a number of studies have shown that institutional environment in which the poor exist conditions welfare outcomes, thus highlighting the inherently crucial importance of institutions for poverty reduction. The institutions of property rights and collective action are among those identified as playing a major role in the livelihood strategies of the poor. This paper highlights ways to operationalize the conceptual framework developed by Di Gregorio and colleagues (2008), which provides an analytical tool to study poverty through the institutional lens with a special focus on collective action and property rights. By emphasizing the multidimensionality of poverty, the authors...

Collective Action and Vulnerability: Burial Societies in Rural Ethiopia AgEcon
Dercon, Stefan; Hoddinott, John; Krishnan, Pramila; Woldehanna, Tassew.
Collective action can help individuals, groups, and communities achieve common goals, thus contributing to poverty reduction. Drawing on longitudinal household and qualitative community data, the authors examine the impact of shocks on household living standards, study the correlates of participation in groups and formal and informal networks, and discuss the relationship of networks with access to other forms of capital. In this context, they assess how one form of collective action, iddir, or burial societies, help households attenuate the impact of illness. They find that iddir effectively deal with problems of asymmetric information by restricting membership geographically, imposing a membership fee, and conducting checks on how the funds were spent....

Commodity Price Volatility and Nutrition Vulnerability AgEcon
Verma, Monika; Hertel, Thomas W..
In this paper we examine the impact of commodity price volatility on nutritional attainment of households at the nutritional poverty line in Bangladesh. We focus on the first two moments of the distribution of nutrition and consider the differential impacts across socio-economic groups within the country. We also examine the direction and magnitude of the shift in these moments as a result of implementation of special safeguards measures aimed at preventing import surges.
