A noção de desenvolvimento rural aqui apresentada tem como fundamento a Abordagem das Capacitações, proposta por Amartya Sen. O desenvolvimento é ético e multidimensional, e envolve a necessidade de se enfrentar a pobreza e a vulnerabilidade. A pobreza é tida como a falta de liberdade para as pessoas levarem a vida que julgam ser a melhor. A vulnerabilidade é uma situação sócio-econômica na qual a pessoa está piorando a sua situação de bem-estar e tende a acentuar isto mediante um fator exógeno. A pobreza e a vulnerabilidade estão próximas, mas não são a mesma coisa: a vulnerabilidade está no limiar da pobreza, assim a pessoa que está mais vulnerável tende a ficar pobre, ou se já é, pode ter sua pobreza intensificada. Como fator exógeno que tende a aumentar a vulnerabilidade e a pobreza foi estudado o caso da seca no noroeste do estado do Rio Grande do Sul, mais propriamente no município de Santo Cristo. A seca é um fenômeno sócio-econômico que começa em uma situação prévia de vulnerabilidade, já vivida pelas pessoas, e que tende a acentuar a pobreza e a vulnerabilidade com a estiagem e suas decorrentes conseqüências. Para dar conta da multidimensionalidade e complexidade desses fatores, sua análise foi feita a partir da Abordagem das Capacitações...

O conhecimento acerca do contexto da organização familiar é fundamental para que se possa estabelecer um planejamento adequado das ações de saúde voltadas à promoção de seu bem estar. Situações de vulnerabilidade que interferem no ambiente onde a criança e sua família estão inseridas são traduzidas por condições inadequadas de vida e desenvolvimento. A composição do ambiente em que as atitudes de transformação dos condicionantes de vulnerabilidades estão alocadas é afetada pelo fato de se possuir um filho convivendo com uma patologia crônica e de prognóstico reservado. Este estudo objetivou conhecer as percepções dos familiares sobre as situações de vulnerabilidade e seus componentes relacionados com o ambiente ecológico e que influenciam no crescimento e desenvolvimento de crianças portadoras de doenças crônicas. Trata-se de uma pesquisa qualitativa na perspectiva de um estudo exploratório descritivo, apresentando como contexto as Unidades de Internação Pediátrica do Hospital de Clínicas de Porto Alegre e tendo nove participantes, familiares de crianças, com doença crônica, hospitalizadas. Para a coleta de informações utilizou-se o Método Criativo Sensível, por meio de dinâmicas de criatividade e sensibilidade...

The increasing concern and consequent appraisal on durability, conservation state and change of use of old buildings in urban centres is greatly related with structural safety assessment, particularly to seismic actions. It is largely recognised that the seismic vulnerability of the majority of historical city centres, with buildings without adequate seismic capacity, is high. The need to catalogue buildings according to their seismic vulnerability, particularly traditional buildings, is a key issue in any renewal or rehabilitation process. Recently, different methods for seismic vulnerability assessment have been proposed, with different levels of detail. Research carried out on seismic vulnerability have underlined that the performance of traditional buildings under earthquake actions is governed by several structural features, some of which can be peculiar of each urban context and construction technology. Seismic vulnerability assessment extended to whole historic centres has outlined the importance of GIS mapping applications in order to aid in the intervention and risk management plans. The need for an integrated multi-purpose tool, connected with a GIS, as well as with a relational database, in order to have a deeper and interdisciplinary knowledge of the site and hence to be able to create a modular approach and manage the historical building stock...

Dissertação de Mestrado em Engenharia Civil; Este estudo avaliou a vulnerabilidade das águas subterrâneas à poluição, da bacia hidrográfica do Rio Cabril, aplicando os métodos DRASTIC e GOD. Esta bacia localiza-se nas imediações da cidade de Vila Real, sendo o Rio Cabril afluente do Rio Corgo. O principal objectivo deste estudo foi a comparação das duas metodologias aplicadas. O método DRASTIC considera 7 parâmetros para avaliar a vulnerabilidade das águas subterrâneas, procurando sistematizar a determinação do potencial do poluente em alcançar a zona saturada. Por sua vez o método GOD é simples e sistemático, apenas considera 3 factores. Este método determina a vulnerabilidade intrínseca pelo que não toma em conta o tipo de poluente. Como resultado da aplicação obtiveram-se o mapa GOD e o mapa DRASTIC. No entanto para melhor comparar estes mapas finais de vulnerabilidade, converteram-se os intervalos dos índices DRASTIC para uma escala normalizada de 0,0 a 1,0 valores, ficando em igual escala de classificação que o método GOD. Constatou-se assim que através do método GOD, a área da bacia apresentou na sua maioria baixa vulnerabilidade (0,1 – 0,3) e vulnerabilidade desprezível (0,0 – 0,1)...

Freshwater fishes are highly vulnerable to human-caused climate change. Because quantitative data on status and trends are unavailable for most fish species, a systematic assessment approach that incorporates expert knowledge was developed to determine status and future vulnerability to climate change of freshwater fishes in California, USA. The method uses expert knowledge, supported by literature reviews of status and biology of the fishes, to score ten metrics for both (1) current status of each species (baseline vulnerability to extinction) and (2) likely future impacts of climate change (vulnerability to extinction). Baseline and climate change vulnerability scores were derived for 121 native and 43 alien fish species. The two scores were highly correlated and were concordant among different scorers. Native species had both greater baseline and greater climate change vulnerability than did alien species. Fifty percent of California’s native fish fauna was assessed as having critical or high baseline vulnerability to extinction whereas all alien species were classified as being less or least vulnerable. For vulnerability to climate change, 82% of native species were classified as highly vulnerable, compared with only 19% for aliens. Predicted climate change effects on freshwater environments will dramatically change the fish fauna of California. Most native fishes will suffer population declines and become more restricted in their distributions; some will likely be driven to extinction. Fishes requiring cold water (<22°C) are particularly likely to go extinct. In contrast...

A smart grid is a large, consolidated electrical grid system that includes heterogeneous networks and systems. Based on the data, a smart grid system has a potential security threat in its network connectivity. To solve this problem, we develop and apply a novel scheme to measure the vulnerability in a smart grid domain. Vulnerability quantification can be the first step in security analysis because it can help prioritize the security problems. However, existing vulnerability quantification schemes are not suitable for smart grid because they do not consider network vulnerabilities. We propose a novel attack route-based vulnerability quantification scheme using a network vulnerability score and an end-to-end security score, depending on the specific smart grid network environment to calculate the vulnerability score for a particular attack route. To evaluate the proposed approach, we derive several attack scenarios from the advanced metering infrastructure domain. The experimental results of the proposed approach and the existing common vulnerability scoring system clearly show that we need to consider network connectivity for more optimized vulnerability quantification.

Effective conservation management for climate adaptation rests on understanding the factors driving species’ vulnerability in a spatially explicit manner so as to direct on-ground action. However, there have been only few attempts to map the spatial distribution of the factors driving vulnerability to climate change. Here we conduct a species-level assessment of climate change vulnerability for a sample of Australia’s threatened species and map the distribution of species affected by each factor driving climate change vulnerability across the continent. Almost half of the threatened species assessed were considered vulnerable to the impacts of climate change: amphibians being the most vulnerable group, followed by plants, reptiles, mammals and birds. Species with more restricted distributions were more likely to show high climate change vulnerability than widespread species. The main factors driving climate change vulnerability were low genetic variation, dependence on a particular disturbance regime and reliance on a particular moisture regime or habitat. The geographic distribution of the species impacted by each driver varies markedly across the continent, for example species impacted by low genetic variation are prevalent across the human-dominated south-east of the country...

The Ebola virus disease (EVD) epidemic that has stricken thousands of people in the three West African countries of Liberia, Sierra Leone, and Guinea highlights the lack of adaptive capacity in post-conflict countries. The scarcity of health services in particular renders these populations vulnerable to multiple interacting stressors including food insecurity, climate change, and the cascading effects of disease epidemics such as EVD. However, the spatial distribution of vulnerable rural populations and the individual stressors contributing to their vulnerability are unknown. We developed a Social Vulnerability Classification using census indicators and mapped it at the district scale for Liberia. According to the Classification, we estimate that districts having the highest social vulnerability lie in the north and west of Liberia in Lofa, Bong, Grand Cape Mount, and Bomi Counties. Three of these counties together with the capital Monrovia and surrounding Montserrado and Margibi counties experienced the highest levels of EVD infections in Liberia. Vulnerability has multiple dimensions and a classification developed from multiple variables provides a more holistic view of vulnerability than single indicators such as food insecurity or scarcity of health care facilities. Few rural Liberians are food secure and many cannot reach a medical clinic in <80 minutes. Our results illustrate how census and household survey data...

This work aims to analyze socio-environmental vulnerability in the Zone of Environmental Preservation -9, located in the northern of the city of Natal / RN. This objective was outlined when we noted a large number of households (about 2000) located in an area considered relevant in terms of environmental and social conditions, notably because of the existence of lakes, sand dunes and rivers that contribute to groundwater recharge Dunas/Barreiras Furthermore, this area is widely used for agricultural activities. The methodology used during this research is accorded to the literature review about the concept of vulnerability, consultations in public agencies for data acquisition, field research and questionnaires. Data collected from each category of vulnerability (social and environmental) were tabulated, analyzed and presented as tables, maps and texts. According to theoretical concepts and methodology of Alves (2006), Cutter (1996), Torres (2000), Acselrad (2006) e Hogan e Marandola Junior (2005; 2006; 2007), the research is structured in the preparation of an environmental diagnosis of the neighborhoods of Blue Lagoon and Pajuçara and subsequent analysis of socio-environmental vulnerability in the Zone of Environmental Preservation -9...

Includes bibliography; Capítulos I y V del documento en español publicado con el símbolo LC/R.2086 (90971) y documento en español (91642), ingresados en Biblioteca; Vulnerability is an emerging issue that has been raised repeatedly in sociological analyses at the dawn of the twenty-first century and in debates on public policies aimed at alleviating poverty, promoting upward social mobility and empowering citizens. If this issue has been so topical, it is because a variety of factors, some highly controversial and others difficult to measure accurately, have contributed to the phenomenon. They include: the increasingly unstable macroeconomic context; the frequency with which households lapse into and emerge from poverty, a trend seen even among traditionally secure groups; various signs of fragmentation and social asymmetries; defencelessness against different types of risk, some of which have been growing; and new forms of segmentation of access to important assets in terms of social mobility. Conscious of this situation, national delegations attending the meeting of the ECLAC sessional Ad Hoc Committee on Population and Development held during the twenty-ninth session of the Commission (Mexico, D.F., April 2000) requested the Population Division of ECLAC-Latin American and Caribbean Demographic Centre (CELADE) to prepare a document on social vulnerability.

Caribbean Small Island Developing States are considered to be particularly vulnerable to external shocks that stem from changes in climate and the increase in frequency and magnitude of natural disasters. Quantification of the extent of vulnerability of these islands may be measured by the use of several indices including the Economic Vulnerability Index (EcVI), the Disaster Deficit Index (DDI), the Environmental Vulnerability Index (EVI) and the Social Vulnerability Index (SVI). The capacity to build resilience may be measured by the Economic Resilience Index (ERI). Of importance in the measurement of vulnerability and resilience is the impact on women and children. In order to reduce vulnerability and promote resilience, Caribbean SIDS are urged to develop adaptation strategies. Such strategies include the conduct of indepth studies on natural environmental impacts specifically in terms of biophysical and socio economic impacts. It is also necessary to review best practices in terms of preparedness, resilience building and climate change adaptation in other countries such as Cuba. Addressing vulnerability and building resilience requires appropriate information and data and priority should be given to addressing data gaps. It would also be expedient to classify vulnerability and resilience as regional public goods wherein one country’s benefit does not compromise another country’s ability to benefit. Finally...

In the event of natural disasters, industrial production sites can be affected by both direct physical damage and indirect damage. The indirect damage, which often exceeds the direct ones in value, mainly arises from business interruptions resulting from the impairment of information and material flows as well as from domino effects in interlaced supply chains. The importance of industry for society and the domino effects often result in severe economic, social, and environmental consequences of industrial disasters making industrial risk management an important task for risk managers at the administrative level (e.g. civil protection authorities). Since the possible industrial disaster damage depends not only on hazard and exposure but also on the vulnerability of a system, an effective and efficient industrial risk management requires information about the system’s regionalized vulnerability. This paper presents a new methodology for structural industrial vulnerability assessment based on production factors that enables to assess the regional industrial disaster vulnerability. In order to capture industry-specific vulnerability factors and to account for the processes underlying regional industrial vulnerability, a two-stage approach is developed. This approach combines a composite indicator model to assess sector-specific vulnerability indices (Vs) with a new regionalization method. The composite indicator model is based on methodologies from the field of multicriteria decision analysis (MultiAttribute Value Theory) and the Decision-Making Trial and Evaluation Laboratory Method is applied to correct the (Vs) for interdependencies among the indicators. Finally...

Climate change may shrink and/or shift plant species ranges thereby increasing their vulnerability and requiring targeted conservation to facilitate adaptation. We quantified the vulnerability to climate change of plant species based on exposure, sensitivity and adaptive capacity and assessed the effects of including these components in complementarity-based spatial conservation prioritisation. We modelled the vulnerability of 584 native plant species under three climate change scenarios in an 11.9 million hectare fragmented agricultural region in southern Australia. We represented exposure as species' geographical range under each climate change scenario as quantified using species distribution models. We calculated sensitivity as a function of the impact of climate change on species' geographical ranges. Using a dispersal kernel, we quantified adaptive capacity as species' ability to migrate to new geographical ranges under each climate change scenario. Using Zonation, we assessed the impact of individual components of vulnerability (exposure, sensitivity and adaptive capacity) on spatial conservation priorities and levels of species representation in priority areas under each climate change scenario. The full vulnerability framework proved an effective basis for identifying spatial conservation priorities under climate change. Including different dimensions of vulnerability had significant implications for spatial conservation priorities. Incorporating adaptive capacity increased the level of representation of most species. However...

Previous research has found that victims of crime tend to exhibit asynchronous movement (e.g. Grayson & Stein, 1981), and the fact that victims display different body language suggests that they may be sending inadvertent signals to their own vulnerability (e.g. Murzynski & Degelman, 1996). Body language has also be en linked with s e l f identification as a victim (Wheeler et aI., 2009), and self-identification has be en found to act as a proxy for more severe victimization (Baumer, 2002) and greater fear of crime (Greenberg & Beach, 2004). The first prediction in the present study, then, was that self-perceived vulnerability would be correlated with body language, while number of previous victimizations mayor may not show the same relationship. Findings from the present study indicate that self-perceived vulnerability exhibits a positive correlation with the body language cues that approaches significance r (10) = .45,p =.07, one-tailed. Different types of victimization, however, were not significantly correlated with these cues. A second goal of the study was to examine the relationship between psychopathic traits and accuracy in judgments of vulnerability. Seventy male participants rated the vulnerability of 12 female targets filmed walking down a hallway who had provided selfratings of vulnerability. Individuals scoring higher on Factor 2 and total psychopathy were significantly less discrepant from target self-rat~ngs of vulnerability...

The focus of this thesis is to estimate evacuation vulnerability in a non-specific evacuation context. Three measures were calculated to evaluate the evacuation vulnerability of locations within Frontenac County, Ontario: population/capacity ratios, link removal analysis and the composite vulnerability measure. By utilizing both population/capacity ratios, as typified by Cova and Church (1997), and link removal analysis, a composite estimate of vulnerability can be determined. The composite vulnerability measure integrates the population/capacity ratios and the link removal analysis to examine the effect of link unavailability on evacuation difficulty. Subsequently, a linear regression analysis is utilized to estimate these complex measures incorporating simple variables. These include population, road and dead-end densities. The advantage of a regression analysis is that it can be used in any situation and for any given area. This research demonstrates that evacuation vulnerability of a network is of key importance for identifying which parts of a populated area may need plans put into place before the necessity of an evacuation occurs. Certain road configurations are shown to be more vulnerable than others, particularly neighbourhoods with a limited number of exits. Overall...

Human vulnerability to heat varies at a range of spatial scales, especially within cities where there can be noticeable intra-urban differences in heat risk factors. Mapping and visualizing intra-urban heat vulnerability offers opportunities for presenting information to support decision-making. For example the visualization of the spatial variation of heat vulnerability has the potential to enable local governments to identify hot spots of vulnerability and allocate resources and increase assistance to people in areas of greatest need. Recently there has been a proliferation of heat vulnerability mapping studies, all of which, to varying degrees, justify the process of vulnerability mapping in a policy context. However, to date, there has not been a systematic review of the extent to which the results of vulnerability mapping studies have been applied in decision-making. Accordingly we undertook a comprehensive review of 37 recently published papers that use geospatial techniques for assessing human vulnerability to heat. In addition, we conducted an anonymous survey of the lead authors of the 37 papers in order to establish the level of interaction between the researchers as science information producers and local authorities as information users. Both paper review and author survey results show that heat vulnerability mapping has been used in an attempt to communicate policy recommendations...

In the context of observed climate change impacts and their effect on agriculture and crop production, this study intends to assess the vulnerability of rural livelihoods through a study case in Karnataka, India. The social approach of climate change vulnerability in this study case includes defining and exploring factors that determine farmers' vulnerability in four villages. Key informant interviews, farmer workshops and structured household interviews were used for data collection. To analyse the data, we adapted and applied three vulnerability indices: Livelihood Vulnerability Index (LVI), LVI-IPCC and the Livelihood Effect Index (LEI), and used descriptive statistical methods. The data was analysed at two scales: whole sample-level and household level. The results from applying the indices for the whole-sample level show that this community's vulnerability to climate change is moderate, whereas the household-level results show that most of the households' vulnerability is high-very high, while 15 key drivers of vulnerability were identified. Results and limitations of the study are discussed under the rural livelihoods framework, in which the indices are based, allowing a better understanding of the social behaviouraltrends, as well as an holistic and integrated view of the climate change...

Corbett, James J.; In China, more than 40% of the nation's population lives in coastal areas, where they contribute up to 60% of national GDP. Dense population and great wealth in coastal zones make these areas prone to grave consequences from natural hazards. It is important to have knowledge of disaster risk and vulnerability in coastal areas in order to protect people's lives and property. Social vulnerability is those characteristics that influence the capacity of the community to prepare for, respond to, and recover from hazards and disasters. This research explores the social vulnerability of 238 coastal counties in China to natural hazards, using the place-based Social Vulnerability Index (SoVI ?? ) methodology. The results indicate three patterns of the distribution of social vulnerability along the Chinese coast: (1) the north and south end areas are more socially vulnerable than southeastern areas; (2) counties and county-level cities are more vulnerable than highly developed city districts; and (3) the vulnerability of each county is driven by different factors even though they have similar SoVI scores. By comparing the change in spatial distribution of social vulnerability between 2000 and 2010, the following factors emerge as driving factors of social vulnerability in Chinese coastal counties: urbanization...
