Interpreting science in the real world for sustainable land application

Today's land application practices are designed to effectively treat wastes, and have evolved from earlier practices that centered on cheap disposal with less regard for environmental protection. The major objectives of this paper are to (i) review how current land application practices, and our understanding of them, have evolved over time and (ii) explore how science is used (and sometimes misused or ignored) in the development of design, regulation, and management of sustainable land application. Land treatment technologies have been used effectively for the treatment and recycling of many types of wastewaters and organic residuals for many years. Extensive research and demonstration efforts, as well as experience with pilot- and field-scale projects, have provided the information about soil reactions with contaminants in wastewater and organic residuals needed to design and operate sustainable land application projects. Still, systematic research programs are as important today as ever to support studies aimed at producing information on how soil-based treatment and recycling systems work, to address new areas of concerns as they arise, and continue to improve the overall design, performance, and reliability of land application systems as sustainable soil treatment and recycling systems.     

Reducing life-cycle environmental impacts: An industry survey of emerging tools and programs

Corporate environmental practices have been evolving quite rapidly in recent years, as consumers express their preferences for environmentally friendly products and practices, as manufacturers look “upstream” and inquire into their suppliers' environmental practices due to liability and marketing concerns, and as company operating costs increase as a result of new environmental regulations. New corporate efforts are made to anticipate (rather than respond to) outside environmental pressures, to internalize costs, and to find strategic opportunities or competitive advantages based on company or product environmental performance. This article describes a survey and research project designed to explore one aspect of these evolving corporate practices—the use of analytical tools and associated programs, such as life-cycle assessment and design-for-environment—by companies to account for impacts throughout a product'S life-cycle.     

A comparison of biodegradable municipal waste (BMW) management strategies in Ireland and the Czech Republic and the lessons learned

In order to meet the recycling and recovery targets set forth by the European Union's (EU) Waste and Landfill Directives, both the Irish and Czech governments’ policy on waste management is changing to meet these pressures, with major emphasis being placed upon the management of biodegradable municipal waste (BMW). In particular, the EU Landfill Directive requires reductions in the rate of BMW going to landfill to 35% of 1995 values by 2016 and 2020 for Ireland and the Czech Republic, respectively. In this paper, the strategies of how Ireland and the Czech Republic plan to meet this challenge are compared. Ireland either landfills or exports its waste for recovery, while the Czech Republic has a relatively new waste management infrastructure. While Ireland met the first target of 75% diversion of BMW from landfill by 2010 and preliminary 2012 data indicate that Ireland is on track to meet the 2013 target, the achievement of the 2016 target remains at risk. Indicators that were developed to monitor the Czech Republic's path to meeting the targets demonstrate that it did not meet the first target that was set for 2010 and will probably not meet its 2013 target either. The evaluation reports on the implementation of Waste Management Plan of Czech Republic suggest that the currently applied strategy to divert biodegradable waste from landfill is not effective enough. For both countries, the EU Waste Framework and Landfill Directives will be a significant influence and driver of change in waste management practices and governance over the coming decade. This means that both countries will not only have to invest in infrastructure to achieve the targets, but will also have to increase awareness among the public in diverting this waste at the household level. Improving environmental education is part of increased awareness as it is imperative for citizens to understand the consequences of their actions as affluence continues to grow producing increased levels of waste.     

Establishing Green Roof Infrastructure Through Environmental Policy Instruments

Traditional construction practices provide little opportunity for environmental remediation to occur in urban areas. As concerns for environmental improvement in urban areas become more prevalent, innovative practices which create ecosystem services and ecologically functional land cover in cities will be in higher demand. Green roofs are a prime example of one of these practices. The past decade has seen the North American green roof industry rapidly expand through international green roof conferences, demonstration sites, case studies, and scientific research. This study evaluates existing international and North American green roof policies at the federal, municipal, and community levels. Green roof policies fall into a number of general categories, including direct and indirect regulation, direct and indirect financial incentives, and funding of demonstration or research projects. Advantages and disadvantages of each category are discussed. Salient features and a list of prompting standards common to successfully implemented green roof strategies are then distilled from these existing policies. By combining these features with data collected from an experimental green roof site in Athens, Georgia, the planning and regulatory framework for widespread green roof infrastructure can be developed. The authors propose policy instruments be multi-faceted and spatially focused, and also propose the following recommendations: (1) Identification of green roof overlay zones with specifications for green roofs built in these zones. This spatial analysis is important for prioritizing areas of the jurisdiction where green roofs will most efficiently function; (2) Offer financial incentives in the form of density credits and stormwater utility fee credits to help overcome the barriers to entry of the new technology; (3) Construct demonstration projects and institutionalize a commitment greening roofs on publicly-owned buildings as an effective way of establishing an educated roofing industry and experienced installers for future green roof construction.     

How green is your thumb? Environmental gardening identity and ecological gardening practices

For gardeners, the garden is a significant aspect of identity. The number of people who garden and consider themselves environmentally friendly is growing. This exploratory study investigated whether “environmental gardening identity” is a measurable construct that motivates environmentally-friendly home gardening cultivation practices above that predicted by the previously validated environmental identity scale (EID, Clayton, 2003). A mail questionnaire was sent to a random sample of 800 urban-suburban self-identified gardeners (61% return rate.) The survey contained four sections: (1) the environmental identity scale (EID); (2) a new scale instrument designed to measure environmental gardening identity (EGID), (3) multiple choice questions addressing specific gardening practices, and (4) demographic questions. Results show that environmental identity, as measured by the EID, significantly predicts ecological gardening behavior. Additionally, it was found that the environmental gardening identity scale (EGID) comprises five subscales, all of which are highly correlated with the environmental identity scale (EID), and three of which explain the variability in gardening practices above that explained by the EID. However, it does not appear that these three subscales of the EGID specifically measure identity. Additional analyses show that respondents' reasons to have a garden are linked to the strength of both EID and EGID, especially for those respondents who garden as a way to connect with nature.     

Risk management: Time for innovative approaches

Risk management practices under the current environmental regulations is a long, complex process that considers scientific, technologic, and management factors to develop various regulatory standards and pollution control measures. Using the mandatory enforcement approach, sometimes referred to as “command-and-control”, a set of preliminary environmental goals, such as better air and water qualities, were achieved. However, the information-intensive nature of the risk management process and the lack of flexibility in conventional regulatory methods to changing economic and technologic realities of the decade has created interest among risk managers to examine some innovative management approaches. Above all, environmental problems of a global scale require novel management methods while striving to achieve the desired environmental goals. As the principal analytical tool in risk management, quantitative risk assessment exerts considerable influence on the risk management process. Therefore, advances in risk management are closely associated with scientific developments that enhance the risk assessment process, particularly those efforts aimed at improving human exposure and toxicity assessments. Market incentives, information dissemination, creative enforcement practices, and interagency and intergovernmental interactions were identified as the key elements of innovative environmental risk management practices. This paper will present an overview of the emerging innovative risk management approaches.     

Water reforms in Brazil: opportunities and constraints

The last decade saw repeated attempts to adopt and implement an integrated management of water in Brazil. Internationally established principles, such as water economics and public participation, have influenced the development of a novel regulatory framework for water use and conservation in the country. However, despite changes in policies and in the legislation, the opportunity to address old and new management problems has been largely frustrated by the internal contradictions of the ongoing institutional reforms. A case study of the Paraíba do Sul River Basin demonstrates the distance between, on the one hand, calls for decentralisation and responsibility sharing and, on the other hand, the persistence of bureaucratised and exclusionary practices. The main distortion is the excessive effort expended on the introduction of water pricing and environmental charges, a controversial policy instrument that has dominated the agenda of the new river basin committee, at the expense of addressing river restoration, public mobilisation and environmental justice.     

“A Kiss Here and a Kiss There”: Conflict and Collaboration in Environmental Partnerships

Multistakeholder collaboration in the environmental realm has been increasing steadily over the past decade. This trend is responding to several stimuli, including dissatisfaction with current regulatory regimes, a liberal economic climate emphasizing global competitiveness and short-term returns, and the growing roles of the business and nongovernmental organization sectors in the environmental policy arena. This paper grows out of ethnographic research conducted between 1994 and 1998 with four environmental partnerships in Europe and the United States. The research found all of these partnerships to be marked by practices of conflict minimization and diffusion. Drawing upon illustrative data from one of these case studies, a European Union level initiative aimed at enabling sustainable development in Europe, the paper asks why this was the case, especially given the diverse political and economic interests at stake and the history of contentious relations between the sectors in other venues. Employing a theoretical perspective highlighting the sociohistoric factors involved in these processes, the paper suggests that this proclivity toward nonconfrontational behavior stems in part from two sources: a prominent cultural model that conceptualizes the partnership process as fundamentally nonconflictual in nature, and the promotion of the discourse of ecological modernization over other competing discourses. The paper explores some of the implications of this finding and concludes that environmental partnerships characterized by such nonconfrontational practices risk inadvertently encouraging the delegitimization of conflictual approaches to environmental action and engendering a retreat from radical thinking and innovative environmental solutions.     

CULTURAL EVOLUTION AND WATER MANAGEMENT IN THE SALINAS RIVER VALLEY1

ABSTRACT: This article reports the findings of a case study of a major California water management district's effort to change its management approach. The following key findings and factors have influenced the Salinas basin management plan (BMP) and its progress: (1) the Salinas Valley is an economy dominated by highly sophisticated irrigated agriculture dependent on ground water; (2) a persistent pattern of agricultural overdraft of ground water has hurt growers primarily in the north end of the valley via induced saline intrusion of irrigation wells; (3) a complex set of water institutions, property and water rights, and land lease practices offer little incentive for good stewardship of land and water; and (4) the BMP approach initially may have intensified tension among growers and between growers and other water user groups. Water rules and practices in the Salinas Valley and Monterey County have evolved through a long historical process of adaptations. Therefore, any significant changes in local water use practices need to be understood in terms of cultural change, that is, changes in deeply held values, beliefs, and assumptions. We believe the BMP and the MCWRA are succeeding when evaluated from this evolutionary perspective. The fact that both still exist relatively intact testifies that they are working, albeit slowly.     

Implementing Innovative Drainage Management Practices in the Mississippi River Basin to Enhance Nutrient Reductions

In the Mississippi River Basin (MRB), practices that enhance drainage (e.g., channelization, tile drainage) are necessary management tools in order to maintain optimal agricultural production in modern farming systems. However, these practices facilitate, and may speed the delivery of excess nutrients and sediments to downstream water bodies via agricultural streams and ditches. These nonpoint sources contribute to elevated nutrient loading in the Gulf of Mexico, which has been linked to widespread hypoxia and associated ecological and economic problems. Research suggests agricultural drainage ditches are important links between farm fields and downstream ecosystems, and application of new management practices may play an important role in the mitigation of water quality impairments from agricultural watersheds. In this article, we describe how researchers and producers in the MRB are implementing and validating novel best management practices (BMPs) that if used in tandem could provide producers with continued cropping success combined with improved environmental protection. We discuss three BMPs — low‐grade weirs, slotted inlet pipes, and the two‐stage ditch. While these new BMPs have improved the quality of water leaving agricultural landscapes, they have been validated solely in isolation, at opposite ends of the MRB. These BMPs have similar function and would greatly benefit from stacked incorporation across the MRB to the benefit of the basin as a whole.     

Improving environmental management with full environmental cost accounting

Based on the most comprehensive field research ever conducted in corporate environmental management, this article reports on the integration of environmental impacts into product costing and cost management practices in organizations. It examines approaches for identifying and tracking current environmental costs related to both current and past production. It also develops the need and prospects for a complete analysis of future environmental impacts, including both costs and benefits, and the integration of these elements into a life-cycle costing or full environmental cost accounting model. The prospects for full environmental cost accounting and the related accounting issues are analyzed. Finally, the importance of full environmental cost accounting for improving corporate environmental performance, reducing corporate environmental impacts, and increasing long-term corporate profitability is discussed.     

Economic liberalisation, innovation, and technology transfer: opportunities for cleaner production in the minerals industry

The liberalisation of investment regimes for mining over the past decade is encouraging an inflow of foreign investment for mining and mineral processing projects in developing and former centrally-planned economies. This new investment is occurring at a time of technological change within the international mining industry as market and regulatory pressures lead the most dynamic firms to invest in the development or acquisition of new technologies and management practices. The effective transfer and assimilation of these technologies enable mining companies to combine gains in productivity with improvements in environmental management. Joint ventures and other strategic alliances between inwardly investing firms and the newly privatised or remnant state-owned mining enterprises may provide an effective vehicle for the transfer of the techniques for more productive and cleaner operations. Specific examples of innovative process and remediation technologies are analysed and it is suggested that the ability of innovative technologies to improve competitiveness and sustain best-practice environmental management in the recipient is linked to the transfer and effective acquisition of the capacity to manage the complex processes of technological and organisational change. The paper closes with some recommendations for further research directed towards a systematic examination of this hypothesis.     

Issues for small businesses with waste management

Participation by small and medium enterprise (SME) in corporate social responsibility issues has been found to be lacking. This is a critical issue, as individually SMEs may have little impact on the environment but their collective footprint is significant. The management style and ethical stance of the owner-manager affects business decision making and therefore has a direct impact on the environmental actions of the business. Although adoption of environmental practices to create competitive advantage has been advocated, many businesses see implementation as a cost which cannot be transferred to their customers. After a brief review of pertinent literature this paper reports on an exploratory investigation into the issue. Results show that whereas owner-managers of small enterprises express concern regarding the environment, this does not then translate into better waste management practices.     

Mixed methodology to analyze the relationship between maturity of environmental management and the adoption of green supply chain management in Brazil

The aim of this research is to verify the relationship between the maturity levels of environmental management and the adoption of green supply chain management (GSCM) practices by electro-electronic companies in Brazil. In this work a two-phase research was conducted, with one quantitative and the other qualitative. The quantitative phase aimed to test whether a relationship between the maturity levels of environmental management and GSCM exists, while the qualitative phase tried to detail the characteristics of this relationship. The quantitative phase was conducted through a survey with 100 Brazilian electro-electronic companies and the collected data were processed using Structural Equation Modeling. For the qualitative phase, a multiple case study was conducted with three companies located in Brazil. The results indicate that: (1) The main hypothesis was confirmed and considered statistically valid, indicating that, indeed, the maturity level of environmental management influences the adoption of GSCM practices; (2) a coevolution tends to occur between the environmental maturity and the GSCM practices; that is, the more developed is the company's environmental management, more complex GSCM practices are adopted; and (3) the GSCM internal practices tend to present a greater relative adoption than the external practices; these external practices of GSCM tend to be adopted when the company is inserted in a higher environmental stage and/or operates under a scenario of stronger normative environmental pressure. By the way, this is the first research mixing survey and case studies on GSCM in Brazil.     

Eco-Labeling and ISO 14000: An Analysis of US Regulatory Systems and Issues Concerning Adoption of Type II Standards

/ Current private and public regulatory systems may not provide an optimal degree of regulation for labels bearing environmental information, and established institutions may detract from efforts to provide for better environmental management. The advent of ISO 14000 offers new opportunities for making eco-labeling a meaningful tool to encourage environmental stewardship. While new federal legislation offers the best vehicle to introduce these standards into US law, the slow pace of the legislative process may recommend an alternative system. Multinational and civic-minded firms may be expected to employ private programs to nurture benevolent environmental management practices until more definitive governmental institutions can be put in place.KEY WORDS: Eco-labels; Environmental labeling; International standards; ISO 14000     

Case study: Sonoco's materials reclamation improves environmental performance through quality-based management

Multinational corporations are facing increasing pressures and finding stronger incentives to integrate environmental management into their overall business strategies. National and local environmental regulations are becoming more stringent in Europe, Japan, East and Southeast Asia, Latin America, and many developing countries, and international voluntary standards of environmental management are being endorsed by a growing number of governments. Multinational firms are embracing these standards not only to assure the public of their concern for environmental protection, but also to enhance their competitiveness in international markets. The British Standard 7750, the European Eco-Management and Audit Scheme (EMAS), and the ISO 14000 series are setting new guidelines for effective corporate environmental management. Beyond complying with local and national laws, corporations now have wider latitude in how they adapt their business practices to these emerging environmental management standards. In order to capitalize on that creative latitude, companies must have corporate cultures and internal management systems that allow them to respond quickly and effectively to changing environmental requirements. Exemplary corporate environmental performance is usually related to strong and progressive leadership, a culture that recognizes the importance of environmental protection, and the willingness to operate by quality-based management principles. This article describes how one international corporation, Sonoco, in responding successfully to changing environmental pressures to reclaim and recycle its products in the wake of the solid waste crisis in the United States and more stringent environmental regulations in Europe, used its management competencies and corporate culture to turn what could have been serious barriers to expansion of its core businesses into new opportunities. By adopting a bold materials reclamation program, Sonoco was able to overcome potential limitations on its operations in the United States and abroad and to develop new business segments that benefited the company and the environment.     

Scoring Corporate Environmental Reports for Comprehensiveness: A Comparison of Three Systems

Corporate annual environmental reports can be judged by the comprehensiveness of their coverage; this paper uses three published comprehensiveness scoring systems to judge 28 such reports (mostly dated 1998) from large US corporations. Earlier (nominally 1996) reports from the same companies were previously scored using one or two of the same systems, and the published results are compared with scores from the current round of reports. The scores of all three scoring systems are significantly correlated for the 1998 environmental reports, indicating that to some degree they are scoring the same features, but with quite a lot of scatter between the scores of one of the systems and those of the other two. There is, however, no correlation between the scores on the 1996 reports and the 1998 reports using the same systems on both. Evidently, most of the 1998 reports were not prepared with the intent of maximizing scores from any of the three scoring systems. Although the three systems achieve similar ranking of the 1998 reports for environmental comprehensiveness, the average normalized scores of one of the systems is significantly higher than those of the other two, reflecting a shorter list of topics and one more in keeping with the practices of the report writers. Because the scoring systems measure the number of topics covered and the depth of discussion rather than the quality of environmental performance, maximum scores could be obtained even with poor performance.     

Environmental Impact Assessment and Environmental Audit in Large-Scale Public Infrastructure Construction: The Case of the Qinghai–Tibet Railway

Large-scale public infrastructure projects have featured in China’s modernization course since the early 1980s. During the early stages of China’s rapid economic development, public attention focused on the economic and social impact of high-profile construction projects. In recent years, however, we have seen a shift in public concern toward the environmental and ecological effects of such projects, and today governments are required to provide valid environmental impact assessments prior to allowing large-scale construction. The official requirement for the monitoring of environmental conditions has led to an increased number of debates in recent years regarding the effectiveness of Environmental Impact Assessments (EIAs) and Governmental Environmental Audits (GEAs) as environmental safeguards in instances of large-scale construction. Although EIA and GEA are conducted by different institutions and have different goals and enforcement potential, these two practices can be closely related in terms of methodology. This article cites the construction of the Qinghai–Tibet Railway as an instance in which EIA and GEA offer complementary approaches to environmental impact management. This study concludes that the GEA approach can serve as an effective follow-up to the EIA and establishes that the EIA lays a base for conducting future GEAs. The relationship that emerges through a study of the Railway’s construction calls for more deliberate institutional arrangements and cooperation if the two practices are to be used in concert to optimal effect.     

Environmental Systems and Local Actors: Decentralizing Environmental Policy in Uganda

In Uganda, environmental and natural resource management is decentralized and has been the responsibility of local districts since 1996. This environmental management arrangement was part of a broader decentralization process and was intended to increase local ownership and improve environmental policy; however, its implementation has encountered several major challenges over the last decade. This article reviews some of the key structural problems facing decentralized environmental policy in this central African country and examines these issues within the wider framework of political decentralization. Tensions have arisen between technical staff and politicians, between various levels of governance, and between environmental and other policy domains. This review offers a critical reflection on the perspectives and limitations of decentralized environmental governance in Uganda. Our conclusions focus on the need to balance administrative staff and local politicians, the mainstreaming of local environmental policy, and the role of international donors.
