Hazardscapes in reunified Germany

Abstract

German reunification had significant political, economic, social, and environmental impacts. A major environmental impact involved changes to the German technological hazardscape (especially in the East). Hazardscapes are defined here as the spatial distribution and attributes of human engineered facilities such as industrial plants, military bases and power stations that contain or emit substances harmful to humans and the environment. The purpose of this paper is to explain how and why the German technological hazardscape changed after reunification. A cursory analysis might ascribe hazardscape change to the application of strict West German environmental laws and sophisticated environmental protection technologies to the East. This paper contends, however, that it was a political economy rather than an environmental imperative that drove the changes to the hazardscape, and that this continuing conflict may have serious repercussions on the future environmental health of eastern Germany.     

Environmental damage: distinguishing human from geophysical causes

Abstract

During the past two decades it has become increasingly common to attribute “naturala” disasters and other damaging environmental events to proximate or underlying causes that are socially produced. Through an examination of three cases, two of them historical, this paper demonstrates that underlying causes within the geophysical domain are also important. Few types of environmental damage or disaster stem from unalloyed human causes or geophysical ones; complex intermixtures are the rule.     

Multi-stakeholder microgrids for resilience and sustainability

ABSTRACT

The electricity grid is susceptible to numerous threats, especially severe weather events that have the potential to cause large-scale power outages. This has resulted in an increased emphasis on resilience against these events. Microgrids, small standalone power grids that have the ability to function independently from the greater electricity grid, have significant potential to improve response to environmental and anthropogenic crises. The vast majority of extant microgrids are generally small in scale, and operated under a conventional model of single operator, owner, and user. We argue that the ultimate potential of this approach will be in the development of multi-stakeholder microgrids which can combine a diversity of renewable and conventional power resources to respond to environmental hazards. The addition of stakeholders allows for increased diversification of generation sources, economies of scale, and other increased operational benefits and opportunities. However, there are significant challenges that arise with the additional layer of stakeholders in terms of governance, cost, and technical operations that can cause the multi-stakeholder model to be more difficult to implement. We develop the case for multi-stakeholder microgrids as a response to environmental hazards, and outline the challenges and questions facing the development of this form of microgrid.     

Disaster vulnerability of businesses in the 2001 Nisqually earthquake

Abstract

This paper examines the impacts of the February, 2001, Nisqually earthquake on businesses. Focusing on two hard-hit business districts in Seattle, the study investigates the extent of losses, patterns of disparities, and underlying loss factors. A conceptual framework is proposed of how business vulnerability dimensions contribute to disaster loss. Interviews were conducted with owners and managers of 107 businesses. Data were gathered on impacts, methods of finance, and disaster preparedness. Results showed that business losses were much greater than what standard statistical data would imply. Analysis found that a composite index of vulnerability—based on business sector, size, and building occupancy tenure—provides a very powerful predictor of business loss. Physical damage was a much weaker predictor of loss. Moreover, business recovery was influenced not only by characteristics of the business itself, but also by conditions in the neighborhood.     

How does living with a disability affect resident worry about environmental contamination? A study of a long-term pervasive hazard

ABSTRACT

While a growing body of research within the environmental hazards scholarship examines how disability affects human responses to major, sudden-onset environmental disasters, little attention has been given to understanding how disability affects responses to long-term, pervasive environmental hazards. Research analysing human responses to land and groundwater legacy contamination in residential areas has identified the significance of demographic and psychosocial determinants of worry, however the question of how living with a disability affects resident worry about contamination remains unanswered. This article provides a cornerstone study for exploring the relation between worry about environmental contamination and disability. A study of 486 adults living in 13 urban residential areas in Australia affected by a range of contaminants was undertaken in 2014. Ordinal logistic regression analysis found respondents with a disability were significantly more likely to worry about contamination than those without. People living with a disability had significantly higher amounts of worry about the contamination than those living without. Changes to residents’ daily habits in response to the contamination and perceptions of personal control over exposure to the contamination present important considerations for understanding the implications of worry for people living with and without a disability in the environmental contamination context.     

The secret history of natural disaster

Abstract

This paper explores the failure of historians to properly engage the study of natural hazards. It argues that by focusing mainly on individual calamities, historians have overlooked the larger social and economic forces that have shaped the response to natural disaster over the last century. Two important trends, real estate capitalism and the entry of the state into the political economy of hazards after World War II, are singled out as crucial for understanding US society's response to natural disaster. As a result of these historical forces, risk became a commodity, with harmful environmental consequences.     

Understanding the causes of vulnerabilities for enhancing social-physical resilience: lessons from the Wenchuan earthquake

ABSTRACT

In an effort to understand the social-physical vulnerabilities from the 2008 Wenchuan earthquake, this research established and validated a conceptual model for natural disaster analysis. The earthquake severely impacted the built environment, with many buildings being destroyed in the earthquake and from secondary impacts. This vulnerable environment exacerbated the poverty in the local residents because of the lack of flat land and the inaccessibility of the mountainous areas. Therefore, there was an interactive relationship between the built environment vulnerability and the social vulnerability. Due to general poverty and low education levels, social vulnerability in rural areas is often the result of poor quality building construction; in the event of an earthquake, therefore, most economic losses and casualties are the result of building destruction. To enhance social-physical resilience, measures should be adopted to mitigate the vulnerability of the built environment and society through actions such as land use planning, the use of seismic-resistant technologies, and investment in infrastructure, education, industrial development, and environmental protection. This research extracts the reasons for the vulnerabilities through an examination of the interactions between the natural environment, the built environment, and the local society. The insights gained have significant theoretical and practical implications in assisting vulnerable communities resist and adapt to natural hazards to achieve sustainable development.     

Environmental equity in a sunbelt city: the spatial distribution of toxic hazards in Phoenix,Arizona

Abstract

This paper examines the spatial distributions of industrial facilities emitting toxic substances in the Phoenix, Arizona metropolitan region. The analysis relies on geographic information system mapping of hazardous facilities listed in the Environmental Protection Agency's Toxic Release Inventory (TRI) to assess the spatial distribution of polluting industries in relation to the demographic composition of host neighborhoods. The research addresses four questions: (1) Are there differences between the socioeconomic characteristics of neighborhoods with and without polluting industrial facilities? (2) Is there a relationship between the volume of toxic chemicals released from industrial facilities and the socioeconomic characteristics of host neighborhoods? (3) Is there a relationship between the toxicity of the chemicals released from industrial facilities and the socioeconomic characteristics of those living in proximity? (4) Do alternative methods for determining the distribution of potentially affected populations produce different observed patterns of environmental inequities? The study concludes that there is a clear pattern of environmental inequity in Phoenix based on the location and volume of emissions of TRI facilities. Analysis of the toxicity of emissions found a more equal distribution of risk, reflecting the suburbanization of high-technology industries into predominantly white middle-class communities.     

Heat-health warnings in regional Australia: examining public perceptions and responses

ABSTRACT

Heatwaves are an increasing environmental hazard and an important public health issue in Australia. Heat-health warnings are being adopted widely to promote protective behaviours, but there has been limited evaluation of public responses. This study used a household telephone survey to examine public attitudes and responses to heat-health warnings in regional areas in two Australian states, South Australia and Victoria. The results indicate a high level of recall of heat-health warnings and awareness about managing extreme heat. Respondents viewed heat-health warnings positively, but the effects on behaviour change were variable. Our findings suggest that the warnings may be reinforcing existing protective behaviours more than promoting change. Perceptions of heat risks were higher among women than men, but lower in older age groups. Evidence of this nature is important to identify ways to improve heat-health warnings and more effectively address the public health risks.     

Forgetting about hazard

Abstract

This paper examines long-term recovery outcomes of businesses impacted by major natural disasters. Data were collected via two large-scale mail surveys—one administered to Santa Cruz County, California businesses 8 years after the Loma Prieta earthquake and the other administered to businesses in South Dade County, Florida, 6 years after Hurricane Andrew. Based on the results of OLS regression models, we argue that long-term recovery experiences of businesses are affected by various factors, including the economic sector in which a business operates, its age and financial condition, and the scope of its primary market; direct and indirect disaster impacts, including physical damage, forced closure, and disruption of operations; and owner perceptions of the broader economic climate. Previous disaster experience, level of disaster preparedness, and use of external sources of aid were not found to significantly affect the long-term economic viability of businesses in the two study communities.     

The plight of some of the poorest of the poor: vulnerabilities of fishing families on Kutubdia Island,Bangladesh

ABSTRACT

Globally, fisheries are important economic resources and support many coastal communities, but the people that rely on fishing experience a range of environmental hazards. This research surveyed 300 fishing households on Kutubdia Island, Bangladesh, regarding their fishing activities and the conditions and perceptions of risk while fishing at sea. This is an artisanal fishery of small boats used for day trips, and larger but still simple boats used for multi-day trips farther offshore. Many households (62%) reported sickness or health problems while at sea. Medicine or first aid kits are carried by only 35% of the boats. Hazards encountered at sea included bad weather (69%), pirates (60%), unfriendly encounters with larger boats (20%), and engine failure (13%). The 300 households reported that 109 fishers had been lost at sea during the past 21 years. From this we estimate an annual death rate of 1335 per 100,000 fishers here, making it among the most dangerous in the world. Bangladesh needs a regulatory framework for its fisheries to include environmental, economic, political, cultural, and social components. Such a regulatory arrangement would support the Kutubdia fishers and should be incorporated into Bangladesh’s national policy for achieving its sustainability goals.     

The hazards of one's faith: hazard perceptions of South Carolina Christian clergy

Abstract

Hazards take place in multiple contexts, contributing to the decisions we make in the face of a threat. Religious belief is considered an important contextual factor in how people understand and respond to environmental hazards. The objective of this paper is to examine one aspect of religious affiliation, biblical orientation, for its influence on the perception of hazard events. Using a survey of individual Christian clergy in South Carolina, the variation in hazard perception and anticipated mitigation responses among the clergy are explored. Geographic location and past hazard experience were found to be strong indicators of hazard concern, while an adherence to a particular theological doctrine was much less conclusive. The hazard mitigation choices voiced by the clergy were also consistent with little variation across the denominations investigated. While considerable differences were noted between the clergy regarding their view of hazard frequency, hazards and the second coming, and biblical orientation, few connections were established between these variables, hazard perception, and future mitigation behavior. Although past research has established that religious orientation influences one's view of their environment, this study demonstrates that this viewpoint is not necessarily extended to environmental extremes. Future opportunities to investigate the complexity of the religion-hazard nexus, such as whether the same results would have occurred in a different geographic region or if these results of individual clergy perceptions can shed light on larger religious attitudes toward hazards, are also discussed.     

Small island developing states: natural disaster vulnerability and global change

Abstract

This paper sets out an examination of natural disaster amongst small island developing states (SIDS), and presents a framework for assessing the interaction of global pressures and local dynamics in the production of human vulnerability. Change at the global level is found to be a source of new opportunities as well as constraints on building local resilience to natural disaster. Much depends on the orientation of the state in global economic and political systems. The United Nations is a key global actor with relevance to shaping vulnerabilityin island states, and the impact of the UN Decade for Natural Disaster Reduction is reviewed. It is concluded that this is a critical time for SIDS which must contend with ongoing developmental pressures in addition to growing pressures from risks associated with global environmental change and economic liberalisation that threaten their physical and economic security.

Economic resilience to natural and man-made disasters: Multidisciplinary origins and contextual dimensions

Economic resilience is a major way to reduce losses from disasters. Its effectiveness would be further enhanced if it could be precisely defined and measured. This paper distinguishes static economic resilience—efficient allocation of existing resources—from dynamic economic resilience—speeding recovery through repair and reconstruction of the capital stock. Operational definitions are put forth that incorporate this important distinction. The consistency of the definitions is examined in relation to antecedents from several disciplines. The effectiveness of economic resilience is evaluated on the basis of recent empirical studies. In addition, its potential to be enhanced and eroded is analyzed in various contexts.     

New tools for emergency managers: an assessment of obstacles to use and implementation

This paper focuses on the role of the formal response community's use of social media and crowdsourcing for emergency managers (EMs) in disaster planning, response and recovery in the United States. In‐depth qualitative interviews with EMs on the Eastern seaboard at the local, state and federal level demonstrate that emergency management tools are in a state of transition—from formal, internally regulated tools for crisis response to an incorporation of new social media and crowdsourcing tools. The first set of findings provides insight into why many EMs are not using social media, and describes their concerns that result in fear, uncertainty and doubt. Second, this research demonstrates how internal functioning and staffing issues within these agencies present challenges. This research seeks to examine the dynamics of this transition and offer lessons for how to improve its outcomes—critical to millions of people across the United States.     

Towards an integrated approach of disaster and environment management: A case study of Thua Thien Hue province,central Viet Nam

Disasters and environmental degradation create serious problems all around the world. They are inherently linked, but little attention is paid to their interaction, particularly at local levels. The degree of integration of disaster management and risk analysis with environmental management programs in relation to human vulnerability has been examined in Thua Thien Hue Province, Central Viet Nam. Unsustainable agricultural practices, and inappropriate development programs have contributed substantially to the increase of disaster risks. On the other hand, disasters damage natural resources and reduce environmental quality, indirectly contributing to increasing poverty which in turn, adds to the vulnerability of both natural and human systems, so further increasing disaster losses. Notwithstanding, in Viet Nam, there is a big gap between disaster and environment management policies and programs. In order to bridge the gap, an integrated approach in which environment-disaster linkage, rural—urban linkage, and poverty are brought into focus as core aspects of disaster management.     

Exploring the use of satellite images in the estimation of potential malaria outbreak regions

Malaria outbreaks affect nearly 40 per cent of the earth's population, most of whom live in tropical and subtropical zones. Malaria is an infectious disease that is transferred by the female mosquito of the species Anopheles. The life cycle of the malaria parasite develops in the anopheline and in the human body. These parasites require suitable environmental conditions in order to complete their development cycles within the mosquito. The relevant parameters are temperature, humidity, vegetation and water. A temperature range of 25–35°C and relative humidity range of 50–80 per cent is suitable for developing malaria outbreaks. As the fly-range of the mosquito is limited to 2–4 km, and since water pools are necessary for breeding, the vector abundance is significantly higher around water bodies. Vegetation cover also has an indirect role on malaria vector abundance. To seek to locate the regions with high potential for malaria outbreaks, we have constructed an experimental map of above-mentioned parameters via remote sensing images. A 7ETM⁺ image of Landsat platform is used in this study and maps of parameters such as land surface temperature, air temperature, air humidity, water pools and vegetated area were produced. However, a weighted combination of these layers showed some poor agreement with the distribution of positive malaria cases collected in the health centres in the region. The methodology first developed in this study is fast and accurate enough to be relied on for forecasting purposes, and could eventually lead—after further research and proper correlations—to improving the targeting of mitigation and relief operations by local health and related organizations.     

Mapping social vulnerability to flood hazard in Norfolk,England

In this paper, we present a method to assess social vulnerability through the creation of an Open Source Vulnerability Index (OS-VI). The OS-VI provides context to environmental hazards and allows NGOs and local agencies to better tailor services and provide targeted pre-emptive vulnerability reduction and resilience-building programmes. A deductive indicator-based approach is utilised to incorporate a wide range of vulnerability indicators known to influence vulnerability. Unlike many vulnerability indices, the OS-VI incorporates flood risk as well as the loss of capabilities and the importance of key services (health facilities and food stores) through the measurement of accessibility when determining an area's level of social vulnerability. The index was developed using open-source mapping and analysis software and is composed completely of open-source data from national data sets. The OS-VI was designed at the national level, with data for all proxy indicators available across the entirety of England and Wales. For this paper, a case study is presented concerned with one English county, Norfolk.

Highlights

• We produce an open-source vulnerability index.

• Accessibility to health care found to be severely affected by flooding.

• High vulnerability areas found to be disproportionately impacted by flooding.

• Urban extent of an area found to increase its level of vulnerability.

• Flood affected areas more likely to be composed of elderly, sick and poor.
