Managing Indirect Environmental Impact within Local Authorities' Standardized Environmental Management Systems

Many local authorities use standardized environmental management systems (EMSs) to improve their environmental management. These authorities often find it difficult to manage environmental impact caused by their exercise of authority i.e. indirect environmental impact (IEI) within their EMSs. Since this is connected to their core activities, it is important to understand how IEI could be more efficiently managed with respect to EMS work. The purpose for this paper is to study if and how IEI could be managed within the framework of EMS. In this study we have identified two different approaches to managing IEI. Because managing IEI is complex, it is often ignored when initiating EMSs or managed by explicitly avoid mentioning the concept. Managing IEI is seen as a matter of maturity within the organization. The paper concludes with a discussion regarding a developed definition of IEI and how management of IEI could be facilitated.     

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.     

Managing Alberta's water: the decision-making process

Land and water are Canada's most valuable renewable natural resources. Canada possesses one-quarter of the world's known volume of fresh water. Fresh water covers 75369000 hectares of 7.1% of the country's surface. This area represents a very substantial number oflakes, rivers, streams, deltas and bays and is perhaps Canada's most vital and strategic resource. Canada has to have ab overall plan of management which provides direction, coordination, and assistance for the management of its water resources at the provincial and regional levels.

Wildlife management: Managing the hunt versus the hunting experience

Deer hunter satisfaction is investigated from two perspectives, (1) satisfaction with the hunt/harvest and (2) satisfaction with the overall hunting trip experience. Regression analysis is used to determine what variables best predict satisfaction with the hunt and the hunting experience. Results indicate that animal population variables (number of deer seen, shot at, bagged) are the best determinants of a quality deer hunt, while environmental (outdoors) and social (crowding and hunter behavior) are the best predictors of a quality hunting trip experience. Wildlife managers and researchers need to realize that deer hunters view the hunt/harvest as different from the hunting trip experience and need to manage for both aspects of hunter satisfaction.     

Managing the metropolitan environment: the challenge for European cities

Traditional approaches to metropolitan management have placed stress upon the achievement of physical and economic growth. In recent years attention has turned to environmental concerns and the achievement of sustainable urban development. It is important to define the objectives for the sustainable development of cities and to identify the principles upon which such development can be based.     

Managing Public Forests: Understanding the Role of Collaborative Planning

/ As federal land management agencies such as the USDA Forest Service increasingly choose to implement collaborative methods of public participation, research is needed to evaluate the strengths and weaknesses of the technique, to identify barriers to effective implementation of collaborative processes, and to provide recommendations for increasing its effectiveness. This paper reports on the findings of two studies focused on the experiences of Forest Service employees and their external partners as they work to implement collaborative planning processes in national forest management. The studies show both similarities and differences between agency employees and their partners in terms of how they evaluate their collaborative experiences. The studies reveal that both Forest Service employees and external partners are supportive of collaborative planning and expect it to continue in the future, both see the trust and relationships built during the process as being its greatest benefit, and both see the Forest Service's organizational culture as the biggest barrier to effective collaborative efforts. The groups differed in terms of evaluating each other's motivation for participating in the process and in whether the process was a good use of time and resources, with external partners seeing it as too drawn out and expensive. The paper concludes with a discussion of the policy implications and changes necessary to increase the effectiveness of collaborative efforts within the Forest Service and other federal land management agencies.KEY WORDS: Public land management; Collaborative planning; National forests; Public participation     

Managing the cooling capacity of the upper rhine: A case study

In most industrialized countries, environmental standards exist which prescribe the maximum allowable man-made increase in water temperature of a river. Together with flowrate and weather conditions, these standards determine the rate at which waste heat may be discharged into a river at any moment. Power generating stations with variable cooling systems can adjust their heat discharge into the river in compliance with environmental standards and by doing so exert an influence on power generation capacity. In this paper, a scheme is developed that allows a chain of power stations discharging into the same river to operate their cooling systems such that the output of total electricity is maximized and water temperature standards are accomodated. The optimum balance between stations is determined through dynamic programming. From the results of a simulation model using historical data, simple decision rules for day-to-day operation are abstracted. These rules are based solely on the river flow rates at each power station.     

Environmental Education: Biodiversity

Environmental education was a principal topic on the agenda of the Stockholm 1972 Conference. In response to its recommendation UNESCO and UNEP developed and launched the International Environmental Education Program (IEEP) in 1977. Environmental education was perceived to encompass in-school and out-of-school activities and public awareness. Later developments added training to its objectives and the concept of sustainable development to its dimensions. The international Convention on Biological Diversity (CBD) represented a phase in the world commitment to conservation of nature. It underpinned biodiversity in the fields of environmental education. Biodiversity education is based on five pivots: scale of boundaries (from local to worldwide), perspectives, goals, themes (vary according to actors), and assimilation (evaluation of programs of action). Directions relate to learners and teachers, and processes address: awareness, school education, education (and professional training) at tertiary level, roles of communication and media institutions.     

Evaluating and Managing Cumulative Effects: Process and Constraints

Since any proposed activity could contribute to a wide range of potential CEs at different spatial and temporal scales, a tiered or nested approach should be followed to assess CEs. The difficulty of assessing and predicting CEs also suggests that in many cases the most efficient approach is to focus on minimizing on-site impacts. Under some circumstances adaptive management can also be a viable alternative to detailed CE assessments. Regular monitoring and feedback is critical to the successful management and regulation of CEs.     

Managing Radioactively Contaminated Land: Implications for Habitat Diversity

Radioactive contamination of agricultural land may necessitate long-term changes in food production systems, through application of selected countermeasures, in order to reduce the accumulation of radionuclides in food. We quantified the impact of selected countermeasures on habitat diversity, using the hypothetical case of two agricultural areas in Finland. The management scenarios studied were conversions from grassland to cereal production and from grassland and crop production to afforestation. The two study sites differed with respect to present agricultural production: one being predominantly cereal production and seminatural grasslands, while the other was dominated by intensive grass and dairy production. Some of the management scenarios are expected to affect landscape structures and habitat diversity. These potential changes were assessed using a spatial pattern analysis program in connection with geographic information systems. The studied landscape changes resulted in a more monotonous landscape structure compared to the present management, by increasing the mean habitat patch size, reducing the total habitat edge length and reducing the overall habitat diversity calculated by the Shannon diversity index. The degree of change was dependent on the present agricultural management practice in the case study sites. Where dairy production was predominant, the landscape structure changes were mostly due to conversion of intensive pastures and grasslands to cereal production. In the area dominated by cereal production and seminatural grasslands, the greatest predicted impacts resulted from afforestation of meadows and pastures. The studied management changes are predicted to reduce biodiversity at the species level as well as diminishing species-rich habitats. This study has predicted prominent side effects in habitat diversity resulting from application of management scenarios. These potential long-term impacts should be considered by decision-makers when planning future strategies in the event of radionuclide deposition.     

Managing Congestion: Economics of Price and Lottery Rationing

It is not uncommon for the carrying capacity for congestible facilities to be estimated before the allocation method is known. This paper shows how efficient capacity differs between two competing resource allocation mechanisms, one which is efficient (price) and one which is fair (lottery). The welfare theoretic implications of adopting lottery allocation rather than price allocation are illustrated from the perspectives of economic efficiency and the benefits obtained by resource users and suppliers. It is found that risk-neutral resource users will always prefer lottery allocation to price allocation. While price allocation is efficient, it is never in risk-neutral resource users» interests to have price allocation imposed. Conclusions are tested using a linear constant crowding demand function, in which case it is found that the efficient capacity for lottery rationing exceeds the efficient capacity where price is to be used to allocate a congestible resource. Objectives may be better met by joint use of allocation mechanisms, the implications of which are investigated using the linear demand model.
