Environmental impact studies: An interdisciplinary approach for assigning priorities

The cross-impact assessment process (CAP) is presented as a practical method for efficiently identifying a parsimonious set of critically important variables and associated relationships needed to conduct environmental impact studies. CAP was developed from the logic of a number of techniques that are collectively referred to as cross-impact analysis. The process is based on a series of structured workshops. The participants represent a variety of disciplines and individual members are selected because they have both the depth of understanding necessary to contribute specific knowledge on the environmental impact assessment problem and the breadth of view to integrate that knowledge with the information provided by other panelists. The results of the workshops are summarized in an importance index and presented in a cross-impact matrix. CAP is illustrated with an example from an Upper Mississippi River recreation impact study, but it can also be applied to any environmental impact assessment problem that can be characterized as a system of variables and relationships. CAP also provides an efficient and reasonably objective means for assigning priorities to environmental impact studies.

Environmental hazards and psychopathology: Linking natural disasters with mental health

For some years, social scientists have been unable to agree on the extent to which experiencing a natural disaster is related to the presence of psychopathological symptoms Indeed, social scientists appear to be well-polarized, some arguing that disasters cause severe negative psychological reactions in victims, with others claiming that any psychological effects, if they exist at all, are minor and transient This paper reviews the controversy and identifies numerous conceptual and methodological difficulties associated with the competing positions. It is argued that the preoccupation of researchers with documenting positive or negative instances of psychological effects has lead them to ignore the issue of identifying processes through which disasters might impinge upon an individual's emotional stability. As a first step toward sketching out these processes, an extensive review of the literature on human response to natural disasters is undertaken. Eleven variables—level of community preparedness, scope of impact, duration of impact, destruction of kin and friendship networks, property damage, pre-impact psychological stability, social support, grief reactions, availability of institutional help, and successful coping skills—are identified as important in determining the psychological impact of disasters. These variables are operationalized and arranged into an interpretative framework that postulates the nature and magnitude of the interrelationships among them based upon the existing research literature     

Providing content for Environmental Health: evaluation of local environmental health programmes in Finland

This article studies the contents of environmental health as presented through local environmental health programmes, an integrative tool introduced by the World Health Organisation to promote the local implementation of environmental health. The analysis looks at the impacts and issues in programme documents, and the organisational aspects of programme preparation. It finds that although there is an understanding of the broad meaning of environmental health in the definitions and impacts used in programmes, more profound change in the substance of environmental health is not yet evident.

Stockpiles of obsolete pesticides and cleanup priorities: A methodology and application for Tunisia

Obsolete pesticides have accumulated in almost every developing country or economy in transition over the past several decades. Concerned about the risks these chemicals pose to nearby residents, public health and environmental authorities are eager to reduce health threats by removing and decontaminating stockpile sites. However, there are many sites, cleanup can be costly, and public resources are scarce, so decision makers need to set priorities. Under these conditions, it seems sensible to develop a methodology for prioritizing sites and treating them sequentially, as budgetary resources permit.This paper presents a new methodology that develops a cleanup priority index for 1915 metric tons of obsolete pesticide formulations at 197 stockpile sites in Tunisia. The approach integrates information on populations at risk, their proximity to stockpiles, and the relative toxic hazards of the stockpiles. What emerges from the Tunisia results is a strategy for sequentially addressing all 197 sites to rapidly reduce potential health damage in a cost-effective way.     

Gully control: Determining treatment priorities for gullies in a network

This report is about a newly developed procedure for setting priorities in gully control. It explains basic gully systems and developments as influenced by geomorphologic processes on which the proposed procedure is based. These processes consist of two types: one, representing interactions between the individual gullies of a network; the other, mechanisms initiated within a given gully by localized instability conditions. Classifying gullies into continuous and discontinuous types not only allows determination of network types but also points to critical locations that must be considered by the designer.The procedure for analyzing gully networks to establish treatment priorities consists of five steps as follows: 1) determining type of network based on gully types; 2) stream ordering of the network gullies; 3) tallying tributaries of each gully; 4) analyzing stage of development of each gully; 5) ranking of treatment priorities.Situations may exist—remote location and negligent downstream effects—where gully control is not desirable and the land manager decides to let nature take its course and to await the establishment of a new stream equilibrium condition before the watershed resources will be intensively utilized. Also political or funding aspects may not permit gully control efforts. Such aspects as well as types of individual treatment measures are beyond the scope of this report. The proposed technique establishes priorities that depend on opportunities to exert greatest control for least cost and to prevent the greatest amount of future erosion.     

Environmental Vulnerability Indicators for Environmental Planning and Decision-Making: Guidelines and Applications

Environmental decision-making and policy-making at all levels refers necessarily to synthetic, approximate quantification of environmental properties such as vulnerability, conservation status, and ability to recover after perturbation. Knowledge of such properties is essential to informed decision-making, but their definition is controversial and their precise characterization requires investments in research, modeling, and data collection that are only possible in the most developed countries. Environmental agencies and governments worldwide have increasingly requested numerical quantification or semiquantitative ranking of such attributes at the ecosystem, landscape, and country level. We do not have a theory to guide their calculation, in general or specific contexts, particularly with the amount of resources usually available in such cases. As a result, these measures are often calculated with little scientific justification and high subjectivity, and such doubtful approximations are used for critical decision-making. This problem applies particularly to countries with weak economies, such as small island states, where the most precious environmental resources are often concentrated. This paper discusses frameworks for a “least disappointing,” approximate quantification of environmental vulnerability. After a review of recent research and recent attempts to quantify environmental vulnerability, we discuss models and theoretical frameworks for obtaining an approximate, standardizable vulnerability indicator of minimal subjectivity and maximum generality. We also discuss issues of empirical testing and comparability between indicators developed for different environments. To assess the state of the art, we describe an independent ongoing project developed in the South Pacific area and aimed to the comparative evaluation of the vulnerability of arbitrary countries.

Sustainable pesticide governance in Bangladesh: socio-economic and legal status interlinking environment,occupational health and food safety

Pesticides, regardless of their known toxic impacts to human health and environment, are widely used in the rapid growing agricultural sectors of developing countries. As an agricultural country with small lands and enormous population to feed, a developing country like Bangladesh rely heavily on the uses of pesticides to increase crop yields. Nevertheless, during the past decades, Peoples’ Republic of Bangladesh has experienced 26.46% decrease in total pesticide consumption. However, the presence of unregistered pesticides in the environmental samples and agricultural products has pointed out the weakness in the existing legal regime of the pesticide governance. This, in turn, is threatening the livelihood and health of the farmers, food safety and consumer health. This paper reviews the antiquity of the status of pesticide consumption, evolution and drawbacks of pesticide in the context of existing socio-economic position of Bangladesh. A consolidated uniform system is lacking to project pesticide management in the country. Existing legal policy, rules and regulations in the context of international agreements regarding pesticide management have been reviewed and suggested for further amendment. Moreover, role of green microfinance in sustainable management of pesticides and food safety were recommended. A framework is proposed for pesticide governance with a stronger pesticide surveillance program and coordination of ministries interlinking environmental, occupational health and food safety.     

Environmental auditing roundtable establishes formal standards for environmental,health, and safety audits

The Environmental Auditing Roundtable recently promulgated the Standards for the Performance of Environmental, Health, and Safety Audits that are featured in this article. With many global initiatives converging in the development of environmental auditing and management standards, this document represents a vital building block, unique from many others in that it was built by a broad-based consensus effort of actual practitioners. Over 95 percent of the Roundtable members who voted on the standard endorsed it.     

Research priorities for coordinating management of food safety and water quality

Efforts to exclude disease organisms from farms growing irrigated lettuce and leafy vegetables on California's central coast are conflicting with traditionally accepted strategies to protect surface water quality. To begin resolving this dilemma, over 100 officials, researchers, and industry representatives gathered in April 2007 to set research priorities that could lead to effective co-management of both food safety and water quality. Following the meeting, research priorities were refined and ordered by way of a Delphi process completed by 35 meeting participants. Although water quality and food safety experts conceptualized the issues differently, there were no deep disagreements with respect to research needs. Top priority was given to investigating the fate of pathogens potentially present on farms. Intermediate priorities included characterizing the influence of specific farm management practices on food safety and improving our understanding of vector processes. A scientific subdiscipline focusing on competing risks is needed to characterize and resolve conflicts between human and environmental health.

Environmental education for engineers: An Australian viewpoint

Summary Australian engineering undergraduate courses of 1987 are described as being devoid of any real environmental content. It is suggested that this is an important omission, for engineers should have a duty to consider the environmental impact of their works. Possible ways in which an environmental component could be added to existing engineering courses are outlined.Prepared by the Environmental Education Subcommittee of the Environmental Engineering Panel of the Sydney Division of the Institution of Engineers, AustraliaHans Bandler is a member of the Environmental Engineering Panel of the Sydney Division of the Institution of Engineers, Australia and its Environmental Education Subcommittee. This paper was prepared and distributed as a Discussion Paper on Environmental Education for Engineering Undergraduates in April, 1987. Preparation of the paper was assisted by a draft document from the Institution of Engineers, Australia's National Committee on Environmental Engineering.
