DETERMINING THE RELATIONSHIP BETWEEN WATER QUALITY AND INFECTIOUS DISEASE IN FISHERY POPULATIONS1

ABSTRACT: Diseases in wild fish populations may have multiple economic and social impacts. Epidemics of infectious diseases, which are associated with the presence of some microbe or parasite, have recently been observed in several major estuarine systems in the eastern United States. The most prevalent of these problems is ulcerative mycosis (UM), a fungal infection. The agents responsible for UM and many of these other diseases are opportunistic pathogens that are not believed to infect normal, immunocompetent individuals. While inroads have been made into determining the infectious agents associated with these diseases, we know very little of how pollution may influence their prevalence. Understanding the importance of pollution requires an awareness of all the environmental conditions that can affect the health of wild populations. In this paper, a multistep examination of the interactions between the host, pathogen(s), and environment is outlined.     

The Assessment of Water Resources Projects Involving Economic, Social and Environmental Costs and Benefits: The World Bank's View

In evaluating the costs and benefits of water resources development projects, the World Bank examines the economic, social and environmental aspects of the project. Some of these aspects are more easily quantified than others. The paper reviews some aspects that have been quantified by the Bank and describes others which have not. By way of illustrating the difficulty of quantification, the Bank's efforts to quantify the health hazards resulting from the introduction of irrigation projects is examined. In addition, the Bank's requirements with respect to social and environmental factors as they affect water resources projects are described.     

Public receptiveness to policies promoting plant-based diets: framing effects and social psychological and structural influences

Governmental and non-governmental organizations, social movements, and academics have called for reductions in meat consumption due to the environmental, animal welfare, and public health consequences of industrial animal agribusiness. An impactful move toward plant-based diets would require changes in public policy. First, we assess if there are different social and structural factors that influence support for policies that promote plant-based diets. We look at four categories of policies (action frames) that will likely reduce meat consumption: environmental, animal welfare, public health, and direct meat reduction. Second, we use a manipulation rhetorical frame to see if support can be altered by providing individuals with information about meat reduction, framing the issue in terms of environmental protection, animal welfare, or public health. Different social and structural factors predict support for different policy groupings, meaning that it matters how policies are enclosed in action frames. However, providing information to individuals about a particular impact (rhetorical frame) has limited influence on policy support.     

Pulsed electromagnetic field therapy history,state of the art and future

Magnetic and electromagnetic fields are now recognized by the 21st century medicine as real physical entities that promise the healing of various health problems, even when conventional medicine has failed. Today magnetotherapy provides a non-invasive, safe, and easy method to directly treat the site of injury, the source of pain and inflammation, and other types of diseases and pathologies. Millions of people worldwide have received help in treatment of musculoskeletal system, as well as pain relief. Pulsed electromagnetic fields are one important modality in magnetotherapy and recent technological innovations, such as Curatron pulsed electromagnetic field devices, offer excellent, state of the art computer controlled therapy system. In this article the development, state of the art and future of pulsed electromagnetic field therapy are discussed.     

Reflexive assessment of practical and holistic sanitation development tools using the rural and peri-urban case of Mexico

Lack of sanitation affects the lives of billions of people worldwide. It is now generally agreed that sustainable solutions to this complex problem require social and cultural factors to be addressed in addition to the habitual economic and technical aspects. Increasingly, sector professionals view the fragmented approaches to sanitation as a limiting factor. This refers to the fragmentation of the knowledge on the subject among often hermetic disciplines and to the distribution of political mandates on sanitation across many institutions, which independently tackle specific aspects of the issue. Holistic approaches have often been suggested as a solution. This paper presents the development of such a holistic approach, designed to assess sanitation development in rural and peri-urban settings. Tested in three Mexican communities, it relies on qualitative research tools to identify critical influences to sanitation development. This article presents generic results about micro and macro-factors affecting sanitation development in Mexican villages, and reflexively examines the research process as well as the strengths and limitations of the approach. The conceptual map developed for each case study successfully highlights the interconnectedness of all factors affecting sanitation development. Despite some weaknesses, these maps constitute a practical assessment tool for interdisciplinary teams deployed in integrated water and sanitation development programs and a valuable didactic tool for training activities.     

Social organization in deer: Implications for localized management

Populations of white-tailed deer (Odocoileus virginianus) inhabiting many state and national parks and suburban areas have grown to the point that they conflict with human activities. Conflicts range from destruction of vegetation through browsing to public perception that diseases carried by deer pose threats to human health. Traditional modes of hunting to control populations are inappropriate in many of these areas because of intense human development and activity. This article explores an alternative approach for population reduction based on deer social organization. Female white-tailed deer are highly philopatric and female offspring remain near their dams for life. This suggests that a population expands slowly as a series of overlapping home ranges in a form analogous to the petals on a rose. Incorporating the rose petal concept into a model of population growth shows that removal of deer by family unit can potentially alleviate conflicts in localized areas for as many as 10–15 yr.

Green jobs for the disadvantaged in British Columbia: the perspectives of non-governmental organisations and social entrepreneurs

This paper examines the actions and potential of green jobs for the disadvantaged, from the perspective of non-governmental organisations and social entrepreneurs. The populations of interest include: low-income, developmentally challenged, those with mental health or addiction issues, women, and First Nations. Findings indicate that green businesses and social entrepreneurs have uniquely engaged in social training and hiring strategies related to green jobs. The major challenges they face include a lack of policies that support the development of green jobs through social training and hiring. As a result of these findings, an argument is made for combining job and life skills for both disadvantaged populations and the agencies that serve them as well as building the capacity of employers to practise social hiring.     

Dilemmas and advances in corporate social responsibility in Brazil. The work of the Ethos Institute

This article discusses the development of corporate social responsibility (CSR) in Brazil from the perspective of the Ethos Institute of Business and Social Responsibility. The Institute is a not‐for‐profit, non‐governmental organization, that has played a leading role in the Brazilian CSR effort. In Brazil, CSR initiatives have a long tradition of philanthropy, a consequence of the country's great social inequalities. The increased attention to corporate social responsibility has paralleled growing concern about sustainable development and the intensifying activities of pressure groups (consumers, customers, investors, NGOs, labour unions, the media, among others) that have been increasing since the 1990s as natural resources are progressively becoming exhausted, social tensions rising and environmental conditions deteriorating worldwide. This article identifies problems and obstacles to the growth of corporate social responsibility in Brazil, as well as advances and alternatives for CSR and towards creating conditions for the country to be internationally competitive and sustainable in the financial, social and environmental areas.     

Assessing local climate action plans for public health co-benefits in environmental justice communities

Climate change presents a complex environmental health and justice challenge for the field of urban planning. To date, the majority of research focuses on measuring local climate efforts and evaluating the general efficacy of adopted climate action plans (CAPs). Cumulatively, these studies argue that socio-economic and demographic variables (such as the fiscal health of cities, city size, and median household income) are important factors in implementing climate policies. Less studied are issues of environmental justice and the impacts of climate change on population health. Through interviews with urban planners and a document analysis of CAPs, this study assesses how California cities with high levels of pollution and social vulnerability address climate change and public health. The findings of this study show that CAPs in these cities rarely analyse whether greenhouse gas reduction strategies will also yield health co-benefits, such as a reduction in the co-pollutants of climate change (i.e. ozone, particulate matter, and nitrogen oxides). In many instances, the net co-benefits of health are not monetised, quantified, or even identified by local governments. In California's most impacted cities, climate planning activities and work on public health are happening in a parallel manner rather than through an integrated approach. The results suggest a need for increased opportunities for interagency coordination and staff training to conduct health analyses, free and easily accessible tools, methods for prioritising funding streams, and the development of partnerships with community-based organisations for linking climate planning with public health.     

Analyzing the Social Factors That Influence Willingness to Pay for Invasive Alien Species Management Under Two Different Strategies: Eradication and Prevention

Biological invasions occur worldwide, and have been the object of ecological and socio-economic research for decades. However, the manner in which different stakeholder groups identify the problems associated with invasive species and confront invasive species management under different policies remains poorly understood. In this study, we conducted an econometric analysis of the social factors influencing willingness to pay for invasive alien species management under two different regimes: eradication and prevention in the Doñana Natural Protected Area (SW Spain). Controlling for the participation of local residents, tourists and conservationists, email and face-to-face questionnaires were conducted. Results indicated that respondents were more willing to pay for eradication than prevention; and public support for invasive alien species management was influenced by an individual’s knowledge and perception of invasive alien species, active interest in nature, and socio-demographic attributes. We concluded that invasive alien species management research should confront the challenges to engage stakeholders and accept any tradeoffs necessary to modify different conservation policies to ensure effective management is implemented. Finally, our willingness to pay estimates suggest the Department of Environment of Andalusian Government has suitable social support to meet the budgetary expenditures required for invasive alien species plans and adequate resources to justify an increase in the invasive alien species management budget.     

Personal,social, and situational factors influencing the consumption of drinking water from arsenic-safe deep tubewells in Bangladesh

Naturally occurring arsenic in groundwater in Bangladesh poses a well-known public health threat. The aim of the present study is to investigate fostering and hindering factors of people's use of deep tubewells that provide arsenic-safe drinking water, derived from the Protection Motivation Theory and the Theory of Planned Behavior. Structured personal interviews were conducted with 222 households in rural Sreenagar, Bangladesh. Multiple linear regressions were carried out to identify the most influential personal, social, and situational behavior determinants. Data revealed that social factors explained greater variance in the consumption of drinking water from deep tubewells than did situational and personal factors. In an overall regression, social factors played the biggest role. In particular, social norms seem to strongly influence deep tubewell use. But also self-efficacy and the perceived taste of shallow tubewell water proved influential. Concurrently considering other important factors, such as the most mentioned response cost (i.e., time needed to collect deep tubewell water), we propose a socially viable procedure for installing deep tubewells for the extended consumption of arsenic-safe drinking water by the Bangladeshi population.     

Analysis of livelihood security: a case study in the Kali-Khola watershed of Nepal

This paper examines household livelihoods in highland and lowland communities of the Kali-Khola agricultural watershed in western Nepal on the basis of economic, ecological and social security indicators. Significant differences were found in soil fertility status, pests and diseases management, risk and uncertainties, use of agrochemicals and access to social services. No remarkable variations were found in crop diversification, annual agricultural income and food sufficiency. However, uncertainty and risk in agricultural production is relatively low in highland communities. The findings reveal that agriculture production alone is not a viable livelihood option for agricultural watershed communities in Nepal. The households growing crops with hired labour have relatively sustainable livelihoods in Nepal's agricultural watersheds. Insufficient agricultural land, insufficient working manpower within a family, and lack of access to ecological agricultural services are prime factors in being livelihood insecure in agricultural watershed communities. Therefore, long-term policies and plans need to be developed for the empowerment of local farmers and to support rural livelihoods with adaptable and flexible income-generating strategies, resilient resource management institutions and enhancement of knowledge, skills and social capital.     

Community perspectives on managing health of peri-urban river system: evidence from the Hawkesbury-Nepean river catchment,Australia

In this study, we examine aspects of community values and perspectives on goods and services received from the river along with issues related to sustainable management of the river. The study reveals that the contemporary values placed on rivers by communities are mostly associated with recreational and leisure activities. The distance from the river and age of the participants appeared as the most influential social demographic factors affecting participants' perspectives on river health. The study indicates that people tend to develop a strong bond with the natural resources around them and the amount of time spent at a location is directly related to the strength of this relationship. To assess the general river condition and health, a number of visual indicators (e.g., floating debris) were suggested. If properly standardised and calibrated, such indicators have the potential to develop cost-effective monitoring tools for detecting seasonal and spatial changes in river health.

Converging disciplinary understandings of social aspects of resilience

Resilience thinking has developed separately in the bodies of literature on social-ecological systems, and that published principally within developmental psychology and mental health on the resilience of individuals. This paper explores what these bodies of literature might learn from the other towards a more integrated and enriched understanding of both social-ecological systems and social resilience. The psychology-based literature recognises a strong set of factors that enhance the strengths of individuals and communities, but lacks a sophisticated integration of the physical environmental context. The social-ecological systems literature offers an excellent foundation in complex adaptive systems, but tends to superimpose ecological concepts of system function onto the human domain, and needs to include an array of core social science concepts that are important to a full understanding of social-ecological systems. An example on north eastern Australia suggests how a converged understanding of social resilience could assist managers to acknowledge, enhance and foster social resilience in linked social-ecological systems.
