Measuring for success in communications for permits

Today, U.S. corporations are discovering the merit of combining the principles of total quality environmental management (TQEM) into their measurement and communications programs. This approach has been particularly productive in the permitting process that is necessary for starting, expanding, or sustaining plant operations—a procedure that can easily be thwarted in the absence of a prominent and aggressive communications component. The need to benchmark and measure such a communication program'S progress is critical both for internal management and for environmental regulators concerned that an applicant demonstrate a high degree of public involvement.

Environmental flows for rivers and economic compensation for irrigators

Securing flows for environmental purposes from an already fully utilized river is an impossible task--unless users are either coerced into freeing up water, or offered incentives to do so. One sensible strategy for motivating users to liberate volumes is to offer them economic compensation. The right amount for that compensation then becomes a key environmental management issue. This paper analyses a proposal to restore and maintain ecosystems on a stretch of the Río Conchos in northern Mexico, downstream from a large irrigation district that consumes nearly all local flows. We present here estimates of environmental flow requirements for these ecosystems and compute compensation figures for irrigators. These figures are derived from crop-specific irrigation water productivities we statistically estimate from a large set of historical production and irrigation data obtained from the district. This work has general implications for river ecosystem management in water-stressed basins, particularly in terms of the design of fair and effective water sharing mechanisms.     

Social Demand for Ecosystem Services and Implications for Watershed Management

We performed a sociocultural preference assessment for a suite of ecosystem services provided by the Kiamichi River watershed in the south‐central United States, a region with intense water conflict. The goal was to examine how a social assessment of services could be used to weigh tradeoffs among water resource uses for future watershed management and planning. We identified the ecosystem services beneficiaries groups, analyzed perception for maintaining services, assessed differences in the importance and perceived trends for ecosystem services, and explored the perceived impact on ecosystem services arising from different watershed management scenarios. Results show habitat for species and water regulation were two ecosystem services all beneficiaries agreed were important. The main discrepancies among stakeholder groups were found for water‐related services. The identification of potential tradeoffs between services under different flow scenarios promotes a dynamic management strategy for allocating water resources, one that mitigates potential conflicts. While it is widely accepted the needs of all beneficiaries should be considered for the successful incorporation of ecosystem services into watershed management, the number of studies actually using the sociocultural perspective in ecosystem service assessment is limited. Our study demonstrates it is both possible and useful to quantify social demand of ecosystem services in watershed management.     

A design for environment methodology for evaluating materials

Industrial ecology is a new multidisciplinary field of study requiring that economic activity be integrated with, and have minimal impact on, surrounding natural systems. This systems-based approach is beginning to be implemented in private firms through the development of Design for Environment (DFE) methodologies and tools which support the integration of technological and environmental considerations in all economic activities. As part of this development process, a matrix system is proposed by the author by which the environmental and energy costs embedded in materials as used in generic applications may be identified, facilitating environmentally and economically efficient selection of materials. This Material Environmental Evaluation Matrix is supported by checklists which inform the evaluation process. A set of completed matrices for major materials in common applications forms the basis for an Environmentally Efficient Materials Database (EEMD). Once completed, the EEMD would inform consumers, product and process designers, business planners and managers, regulators and government purchasers, public interest groups, and others in their choice of optimal, environmentally and economically efficient, material options.

An approach for analysing the potential for material efficiency improvement

Material efficiency improvement saves energy and reduces the consumption of primary resources and reduces the volume of waste. In this article an approach for analysing the potential for material efficiency improvement is proposed and discussed. In this approach the product functions performed by the materials and various improvement measures are taken into account. The potential for material saving and associated energy saving is assessed and evaluated economically. In this paper the approach is tested in an analysis of the potential for material efficiency improvement with respect to plastic packaging in the Netherlands. The technical reduction potential is found to be 34 ± 7% (157 ± 30 ktonne virgin plastics). Realization of this potential would improve the energy efficiency of the lifecycle of plastic packaging by 31% (10 PJ in 1988). From our study we conclude that our approach can indeed be used to investigate the potential for material efficiency improvement. However, a reliable technical and particularly an economical assessment of reduction measures cannot be made until more detailed data become available.     

Criticism of the philosophy for development of standards for non-ionizing radiation

The new recommendations of WHO and EC for legislation in Europe and other countries concerning non-ionizing radiation (NIR) health and safety include exposure limits that are very debatable. ICNIRP Guidelines propose exposure limits for electromagnetic fields in the frequency range up to 300 GHz based on short-term exposures and on thermal effects. The new EC proposal for optical and laser safety legislation includes classification of sources of radiation—both lasers and other optical sources, but not requirements for the methodology of classification. On the other hand, many new requirements have been set by the WHO publication “Model Legislation for EMF Protection” concerning the responsibilities in the field of EMF health and safety. Many specialists in the field of developing exposure limits have positions very far away from the proposed of the ICNIRP Guidelines philosophy. The results are different approaches in developing standards and exposure limits, and differences more than 100 times in maximal permissible levels. We, the Bulgarian Program Committee on NIR, try to organize working groups and discuss different philosophy for developing exposure limits for more than 10 years. This paper exposes our position in this area.     

A method for evaluating areas for national park status

A procedure for evaluating different areas as national parks based on a scoring system is proposed. A National Park Evaluation Form (NPEF) evaluating natural, cultural, and recreational resources in accordance with international criteria for national parks is presented. The evaluation points given to an area indicate the possibility of the area becoming a national park. In this method, subjectivity and bias have been minimized by a special application of the Delphi technique. The method outlined here could help in the efforts of selecting and establishing national parks in many countries.     

Principles for retrofitting coal burners for oxy-combustion

Experiments were performed in a 1.5 MW pilot-scale furnace to investigate the differences between air- and oxy-fired flame behavior from a pulverized coal oxy-research burner designed for flexible operating conditions. The flame behavior was characterized by recording video images of the flames and by measuring radiation intensity along the flame length. Various strategies relating air- and oxy-fired operation of the burner primary register were investigated where the oxy-fired burner primary mass, momentum and velocity were matched to the air-fired conditions. Matching either burner primary mass or momentum under oxy-fired conditions with air-fired conditions resulted in a flame stabilized within the quarl. Matching primary velocity with air-fired conditions resulted in a detached flame indicating a delay in flame ignition for the oxyfired conditions. A decrease in primary velocity of 13% was necessary in order to stabilize a flame within the quarl similar to the air-fired case. Additional experiments also showed a flame could be stabilized with no oxygen enrichment of the primary (～3 vol.%, dry O₂ in the primary). Experiments where oxygen was injected at the burner face indicated injection at the boundary of the primary and secondary flow paths strongly attach a flame and injection at the coal rich primary flow path increased the radiative intensity of the flame.     

A conceptual scheme for aquatic studies: Framework for aquatic curriculum development

Responding to increased concern for an aquatically literate public, the authors discuss the present state of aquatic education curriculum efforts, the need for a comprehensive conceptual scheme for aquatic studies, and the subsequent development and use of the COAST Conceptual Scheme for Aquatic Studies.     

Design for environment: A new framework for strategic decisions

For most of its history of environmental protection, U.S. policy has concentrated on a pollution control strategy based on single medium emissions: air, water, or land. Efforts to mitigate environmental impacts to one medium often resulted in greater impacts to others. While much environmental improvement has occurred via this system over the last quarter-century, it is generally recognized that alternative strategies which address environmental impacts across all media in an integrated manner will be necessary for continued improvement. Increasingly, regulatory strategies that result in only passive compliance will be insufficient to meet these demands. This article demonstrates why new strategies which encourage proactive behavior are necessary. A new framework for making strategic decisions—design for environment—concerning the relation between our actions and environment is necessary to ensure a sustainable future.     

Comparing Onsite and Offsite Methods for Measuring Norms for Trail Impacts

This study examined the comparability of onsite and offsite methods for measuring norms for trail impacts using photo/survey techniques. A total of 449 subjects participated in a study of Mudeung-Mountain Provincial Park, Gwang-Ju, Korea. For the overall photo evaluation method (OPEM), respondents rated the acceptability of bare soil area for each of a series of photographs. For the specific photo evaluation method (SPEM), respondents selected a photograph that illustrated the largest acceptable proportion of bare soil area from a series of 10 photographs. Overall, there were no substantial differences in maximum acceptable impacts between onsite (onsite-I visitor group surveyed at the actual trail points and onsite-II departing visitor group surveyed at the exit area) and offsite (students surveyed in a laboratory setting) groups for the two norm measurement alternatives (OPEM and SPEM). Subjects’ difficulty ratings were low for both methods, and there were no substantial differences in norms between individuals with high and low levels of experience at the park. The offsite method appears to be substitutable for onsite methods in this particular study area, which is a frontcountry setting with a relatively simple range of recreation opportunities. Implications and further studies are discussed.

A hydrological modeling framework for defining achievable performance standards for pesticides

This paper proposes a hydrological modeling framework to define achievable performance standards (APSs) for pesticides that could be attained after implementation of recommended management actions, agricultural practices, and available technologies (i.e., beneficial management practices [BMPs]). An integrated hydrological modeling system, Gestion Intégrée des Bassins versants à l'aide d'un Système Informatisé, was used to quantify APSs for six Canadian watersheds for eight pesticides: atrazine, carbofuran, dicamba, glyphosate, MCPB, MCPA, metolachlor, and 2,4-D. Outputs from simulation runs to predict pesticide concentration under current conditions and in response to implementation of two types of beneficial management practices (reduced pesticide application rate and 1- to 10-m-wide edge-of-field and/or riparian buffer strips, implemented singly or in combination) showed that APS values for scenarios with BMPs were less than those for current conditions. Moreover, APS values at the outlet of watersheds were usually less than ecological thresholds of good condition, when available. Upstream river reaches were at greater risk of having concentrations above a given ecological thresholds because of limited stream flows and overland loads of pesticides. Our integrated approach of "hydrological modeling-APS estimation-ecotoxicological significance" provides the most effective interpretation possible, for management and education purposes, of the potential biological impact of predicted pesticide concentrations in rivers.     

Procedure for assessing visual quality for landscape planning and management

Incorporation of aesthetic considerations in the process of landscape planning and development has frequently met with poor results due to its lack of theoretical basis, public involvement, and failure to deal with spatial implications. This problem has been especially evident when dealing with large areas, for example, the Adirondacks, Scenic Highways, and National Forests and Parks. This study made use of public participation to evaluate scenic quality in a portion of the Niagara Escarpment in Southern Ontario, Canada. The results of this study were analyzed using thevisual management model proposed by Brown and Itami (1982) as a means of assessing and evaluating scenic quality. Themap analysis package formulated by Tomlin (1980) was then applied to this assessment for the purpose of spatial mapping of visual impact. The results of this study illustrate that it is possible to assess visual quality for landscape/management, preservation, and protection using a theoretical basis, public participation, and a systematic spatial mapping process.     

Education for Change

The author uses two publications, Fighting Poverty in the US and Europe (Alesina and Glaeser) and Poetry magazine, to underscore the important role that educational institutions play in developing a person’s political philosophy and imagination. European nations, for instance, have better funded social welfare programs than the US because their system of public education incorporates more liberal or left-leaning teachings into their standard curricula. The author sees implications for a more intentional approach to education in the US for those who are interested in changing the food system. If American educational institutions viewed their role as producing food competent citizens, he argues, then we would be more successful in addressing obesity, promoting a more sustainable food system, and even reducing poverty. Food system activists, dieticians and nutritionists, parents, and elected officials should take a more aggressive position with educational institutions to develop programs, services, and curricula capable of achieving these ends.     

Utilization of Photographs for Determining Impact Indicators for Trail Management

Indicators are a key component of resource management, but selecting them can be difficult and controversial. This study explores different methods for selecting impact indicators for management of trail conditions by comparing photo survey methods (PSM) with written survey methods (WSM). A total of 661 subjects participated in interviews conducted within Mudeung- Mountain Provincial Park in Kwang-ju, Korea. PSM explained variation in acceptability better than WSM. Six major photo components (in order of importance: area of large rocks on trail, area of wood steps, area of bare roots, area of bare soil, area of small stones, and area of stone steps) explained 84.7% of the variation in acceptability of trail management conditions. This study suggests that PSM can be a useful tool for selecting impact indicators. Supported by the grant of Post-Doctoral Program, Chonbuk National University (2001)     

An alternative role for economic instruments: Sustainable finance for environmental management

Economic instruments, such as effluent fees and tradable discharge permits (TDP), have often been suggested by economists as efficient or cost-effective means to control pollution. In recent years such instruments have received increasing attention due to their growing political acceptability. Still, their use in practice has been tentative. The interest in possible application of such instruments has led to a set of studies regarding their practical potential. These studies indicate that economic instruments require substantial government involvement, entailing high administration cost; require restrictions so as to prevent significant deterioration in receptor areas; and have ambivalent effects on innovation adoption. Consequently, the efficiency gains from such instruments may be smaller than potential gains identified in earlier studies. In addition, the distributional impacts of such instruments and their possible adverse effect on market contestability reduce their attractiveness in some cases. These findings raise the question: what is the desired role of economic instruments in addressing environmental concerns? In recent years the demand for environmental services has increased dramatically. Current legislation and studies indicate that desired environmental expenditures are likely to increase. At the same time environmental programs face increasing competition from other programs for a declining pool of general revenues. One outcome of these processes has been the search for alternative sources of funds for environmental programs. Furthermore, as the competition for general revenue funds increases, the allocation of such funds for environmental programs becomes less predictable. This may endanger many long-term environmental programs that require stable funding. This article suggests that economic instruments may prove one source of dedicated funds for many environmental goals. Consequently, studies of environmental-program financing as well as studies of economic instruments may well explore the possible role of economic instruments as financing tools. Some examples of the potential of such tools for estuary cleanup programs are discussed.
