Existential threat and compliance with pro-environmental norms

Recent research on the effects of personal threat suggests that perceived threat might enhance pro-environmental behavior when pro-environmental norms are in focus. In three experiments we found support for the latter assumption, showing that mortality salience and salience of pro-environmental norms interacted in predicting pro-environmental attitudes and information search (Study 1), sustainable behavior in a forest management game (Study 2), as well as pro-environmental intentions and behavior (Study 3). Specifically, mortality salience increased pro-environmental conduct only when pro-environmental norms were salient. Moreover, norm salience only had an effect on pro-environmental attitudes and behavior when the threat of personal mortality was salient. We discuss the implications of these results for both terror management theory and the promotion of pro-environmental behaviors.     

An illicit economy: scavenging and recycling of medical waste

This paper discusses a significant illicit economy, including black and grey aspects, associated with medical waste scavenging and recycling in a megacity, considering hazards to the specific group involved in scavenging as well as hazards to the general population of city dwellers. Data were collected in Dhaka, Bangladesh, using a variety of techniques based on formal representative sampling for fixed populations (such as recycling operatives) and adaptive sampling for roaming populations (such as scavengers). Extremely hazardous items (including date expired medicines, used syringes, knives, blades and saline bags) were scavenged, repackaged and resold to the community. Some HCE employees were also observed to sell hazardous items directly to scavengers, and both employees and scavengers were observed to supply contaminated items to an informal plastics recycling industry. This trade was made possible by the absence of segregation, secure storage and proper disposal of medical waste. Corruption, a lack of accountability and individual responsibility were also found to be contributors. In most cases the individuals involved with these activities did not understand the risks. Although motivation was often for personal gain or in support of substance abuse, participants sometimes felt that they were providing a useful service to the community.     

Household water use behavior: An integrated model

Water authorities are dealing with the challenge of ensuring that there is enough water to meet demand in the face of drought, population growth and predictions of reduced supply due to climate change. In order to develop effective household demand management programs, water managers need to understand the factors that influence household water use. Following an examination and re-analysis of current water consumption behavioral models we propose a new model for understanding household water consumption. We argue that trust plays a role in household water consumption, since people will not save water if they feel others are not minimizing their water use (inter-personal trust). Furthermore, people are less likely to save water if they do not trust the water authority (institutional trust). This paper proposes that to fully understand the factors involved in determining household water use the impact of trust on water consumption needs investigation.     

Knowledge,attitude and behavior of farmers in farmland conservation in China: an application of the structural equation model

We analyzed the relationship between the conservation behavior of farmers and their environmental attitude and knowledge, whilst controlling for exogenous socio-economic factors. We employed the structural equation model with cross-sectional data from 442 farmers from the Guanzhong Plain of China. Results showed that local farmers generally possessed a positive environmental attitude and undertook considerable conservation action. Conservation behavior was directly affected by environmental attitude and indirectly by environmental knowledge (via attitude). Social networks, farm size, land rights, age and incentives were significant exogenous explanatory variables. Thus, understanding the importance of socio-behavioral characteristics, including the environmental attitude and knowledge of farmers, is important for the development of farmland conservation policies. Specifically, farmers in this area were found to significantly depend on each other for information on farmland conservation practices. Thus, role model farmer discussions, dissemination of environmentally friendly techniques via social networks and the rewarding of environmentally friendly behavior among farmers should be used to encourage ongoing restoration endeavors, and thereby help mitigate environmental degradation.     

Social Planning for Mall Redevelopment: an Australian case-study

This paper provides a case study of recent work undertaken in Melbourne relating to a mall re-development project. It begins by discussing the nature of shopping centres as sites of consumption and non-commercial social activities. It then describes planning and development strategies that provide innovative and socially progressive interventions in regard to the social, physical and regulatory environments of public malls. The importance of seeing such sites as 'community spaces', of promoting activities on the basis of social inclusion, of creating a safe, convivial atmosphere, and of establishing low-key friendly sorts of mall management, are highlighted.     

Application of the randomized response technique to marine park management: an assessment of permit compliance

Marine product collecting permits are useful management tools for providing information on usage patterns. Unfortunately, usage parameters based on permit issuance are invariably inaccurate because of permit noncompliance. Since noncompliance is a prosecutable offense, any attempt to estimate the rate of noncompliance by direct survey techniques is met with misleading and evasive responses. It has been shown elsewhere that randomized response designs reduce survey response bias to incriminating questions by ensuring respondent anonymity. With the use of the randomized response survey technique, estimates of permit noncompliance were determined for the Capricornia Section of the Great Barrier Reef Marine Park. Noncompliance with the requirement to obtain the prescribed permit was found to be low whereas, once a permit was obtained, noncompliance with specific permit conditions was considered high. Reasons for the high rate of noncompliance with specific conditions are presented, and it is recommended that marine park managers should not unreservedly base management decisions on usage data derived simply from permit issuance.     

Sorption and transport behavior of naphthalene in an aggregated soil

Soil solution chemistry influences the sorption and transport behavior of hydrophobic organic compounds (HOCs) in soil. We used both batch and column studies to investigate the influence of ionic strengths (0.03 and 1.5 M) and flow velocities (12 and 24 cm h-1) on sorption and transport of naphthalene (NAP) in aggregated soil. Sorption parameters such as the Freundlich coefficient (Kf) and exponent (n) calculated from batch studies and column experiments were also compared. Retardation of NAP transport was greater at higher solution ionic strength, which may be attributed to greater sorption affinity due to enhanced aggregation of the sorbent. The effect of ionic strength on sorption of NAP observed in the batch study was consistent with the results from the column study. The Kf and n values obtained from the batch study for the two ionic strengths ranged from 7.8 to 13.7 and 0.68 to 0.80, respectively, whereas the Kf and n values obtained from the column study ranged from 7.9 to 9.9 and 0.73 to 0.85, respectively. The effluent breakthrough curve (BTC) of NAP at a flow rate of 24 cm h-1 showed significant chemical and physical nonequilibrium behavior, implying that a considerable amount of sorption in aggregated soil was time dependent when flow was relatively fast. The BTCs calculated with the parameters determined from batch studies compared poorly with the measured BTCs. The potential for nonequilibrium transport should be incorporated in models used for predicting the fate and transport of HOCs. Furthermore, caution is required when extrapolating the results from batch studies, especially for aggregated soils.     

Towards an integrative model of place identification: Dimensionality and predictors of intrapersonal-level place preferences

Research on place identity has been hampered by confusion in defining the concept and lacks an integrated account of social and motivational processes underlying people's identification with places. We used multilevel modelling (N = 141) to investigate the dimensionality and predictors of intrapersonal variance in place identification, drawing on psychological and anthropological literatures. Confirmatory factor analysis distinguished three dimensions of place identification (attachment/self-extension, environmental fit, and place-self congruity), and each was predicted by a somewhat different combination of needs and motives (e.g., self-esteem, continuity, distinctiveness, belonging, meaning, security, control, aesthetic pleasure) and social/symbolic links to places (e.g., genealogy, economics, loss, narrative, spiritual significance, special events). Satisfaction of needs and motives partially accounted for effects of social/symbolic links.     

Forest law compliance and enforcement: the case of on-farm timber extraction in Ghana

The paper investigates law compliance in case of on-farm timber extraction in Ghana. It empirically investigates compliance with rules that (i) require timber operators to obtain prior and informed consent from the farmers, (ii) require timber operators to pay appropriate and timely compensation for crop damage caused by timber extraction and (iii) ban chainsaw lumbering. The study documents a low level of compliance in all three domains. Subsequently, the paper discusses the underlying causes for the observed low compliance. The low compliance level is attributed to a legislation, and enforcement, that provides huge financial incentives for non-compliance for both farmers and timber operators, and in the latter case both with and without legal permits. At the same time the regulation is perceived to violate their moral values. The paper underlines the interests of the political elite as decisive in shaping the current regulation and the way it is implemented on the ground. It asserts that eliciting compliance requires consideration of both the instrumental and normative perspectives; else it becomes illusive. The study thus challenges the typical response of governments in developing countries, who, supported by donor agencies, attempt to elicit compliance through enhanced law enforcement efforts. The results presented on the Ghana case suggest that such an approach is unlikely to elicit compliance.     

The environmental auditing privilege debate: Disclosure,compliance, and legislative issues

This article discusses the primary arguments advanced in the debate in favor of and against the adoption of a qualified privilege to protect audit findings and explores various alternative incentives for promoting the practice of environmental health and safety auditing and for encouraging voluntary disclosure of audit findings to the regulators. This article also examines whether establishing a privilege provides the greatest motivation to auditing and disclosure, particularly in the context of EPA's recent reevaluation of its policy on auditing.     

Joint pollution control at a catchment scale: compliance costs and policy implications

Agricultural activities are one of the major drivers of increased nutrient levels such as nitrogen (N) and phosphorus (P) to both terrestrial and aquatic ecosystems. Elevated nutrient concentrations are associated with degraded water quality that can result in potential impacts for human health and the environment. A recent European study has identified elevated concentrations of N and P for many European river monitoring stations. In many cases the management of N and P has been considered separately here we address the multi-dimensional issue of water quality where the simultaneous management and control of both N and P is considered desirable. Using an integrated modelling approach various nutrient management scenarios are examined. It is found that although the control of N and P involve different farm adjustments and induce different land use changes there is a certain degree of complementarity between these two nutrient controls. The policy implication of ignoring such complementarity is that the appropriate environmental taxes to control the required nutrient losses are overestimated, resulting in unnecessary welfare losses to the society.     

Environmental compliance: The good, the bad, and the super green

Although many empirical studies have examined firms' decisions to participate in voluntary environmental programs, relatively few have examined why firms choose different levels of compliance with environmental regulations. This paper uses primary data to examine why some firms violate regulatory standards on water pollution, solid waste, toxic and hazardous waste, and hazardous air emissions, while others over-comply with them. The results suggest that different factors drive decisions to violate or over-comply with an environmental regulation. Some evidence was found to support the strategic behavior theory of environmental overcompliance, but no corroborating evidence was uncovered to support the green consumer theory.     

Environmental occurrences, behavior, fate, and ecological effects of nanomaterials: an introduction to the special series

The release of engineered nanomaterials (ENMs) into the biosphere will increase as industries find new and useful ways to utilize these materials. Scientists and engineers are beginning to assess the material properties that determine the fate, transport, and effects of ENMs; however, the potential impacts of released ENMs on organisms, ecosystems, and human health remain largely unknown. This special collection of four review papers and four technical papers identifies many key and emerging knowledge gaps regarding the interactions between nanomaterials and ecosystems. These critical knowledge gaps include the form, route, and mass of nanomaterials entering the environment; the transformations and ultimate fate of nanomaterials in the environment; the transport, distribution, and bioavailability of nanomaterials in environmental media; and the organismal responses to nanomaterial exposure and effects of nanomaterial inputs, on ecological communities and biogeochemical processes at relevant environmental concentrations and forms. This introductory section summarizes the state of knowledge and emerging areas of research needs identified within the special collection. Despite recent progress in understanding the transport, transformations, and fate of ENMs in model environments and organisms, there remains a large need for fundamental information regarding releases, distribution, transformations and persistence, and bioavailability of nanomaterials. Moreover, fate, transport, bioaccumulation, and ecological impacts research is needed using environmentally relevant concentrations and forms of ENMs in real field materials and with a broader range of organisms.     

Statistical evaluation of an agricultural land suitability model

The land evaluation and site assessment (LESA) method has been used extensively in the United States to assess agricultural land suitability for different localities. Despite widespread use, LESA models rarely have been evaluated in a systematic, comprehensive manner. This article discusses development of a LESA system for Hawaii, the first statewide application of the LESA methodology. The empirical model was implemented with a computerized geographic information system (GIS). The system's efficiency, ability to discriminate among land parcels, and robustness to subjective model parameter values are evaluated with statistical analyses and map overlays of GIS data. Results show great potential to simplify the original model specification, primarily through deletion of marginal site assessment factors. System output was generally insensitive to the numeric values selected for model parameters, with exception of the ratio used to combine the land evaluation (LE) and site assessment (SA) component scores. Relative supplies of the differing land attributes measured by the two components must be considered in determining an appropriate LE:SA ratio for a given area.     

Building a model of commitment to the natural environment to predict ecological behavior and willingness to sacrifice

We examined the connection between individuals’ relationships with the natural environment and their environmental behaviors with a focus on commitment to the environment, defined as psychological attachment and long-term orientation to the natural world. Commitment is theorized to emerge from structural interdependence with the environment and to lead to pro-environmental behaviors. Close relationships research has identified three key antecedents to commitment (satisfaction, alternatives, and investments). We developed environment-specific measures of these constructs, and factor analysis verified three distinct factors. A path analysis revealed that satisfaction with the environment and investments in the environment, but not alternatives to the environment, predicted commitment to the environment. Moreover, commitment mediated the effects of satisfaction and investments on general ecological behavior and willingness to sacrifice for the environment. In regression analyses, commitment predicted general ecological behavior and willingness to sacrifice for the environment, even when controlling for ecological worldview, inclusion of nature in the self, connectedness to nature, and environmental identity. Individuals who are satisfied with and invested in the natural world are likely to be committed to the environment and act with the well-being of the environment in mind.     

The Mersey Basin and its River Valley Initiatives: an appropriate model for the management of rivers?

Concepts of sustainable development have stimulated innovation in the delivery of environmental management. In particular, new partnership approaches have been developed in recognition of the need to adopt more holistic perspectives and facilitate multi-sectoral and cross-sectoral working. River catchments are complex systems and have been one particular focus of experimentation in environmental management mechanisms. This paper provides a brief overview of river management experience in the UK, charting changing approaches in terms of scope and organisation since the 1970s. This sets the context for a more detailed examination of the Mersey Basin Campaign and, in particular, its River Valley Initiatives. The paper concludes with an evaluation of the merits of this approach in relation to sustainable river management.     

Teaching for community environmental action: an alternative instructional model for environmental concepts and issues in schools

Summary Whether environmental education in the school curriculum is treated as a separate subject or as an interdisciplinary entity, the end product should be the same: to provide learners with the desire to preserve or develop optimum environments and to improve less desirable ones. In this endeavour, the learners must ultimately reach out to participate in community decisions and environmental management activities, for that is where the environmental problems abound. Moreover, young persons are generally more knowledgeable than many adults on environmental matters and are more aware of the effects of environmental degradation. When they participate in community environmental management, they may also develop unique and particularly dynamic qualities.Research worldwide suggests that very few teaching programmes encourage environmental participation. In Kenya teachers tend to use deductive teaching methods which do not encourage participation, although there may be ample opportunities in the local environment to facilitate such participation. A more refined, reconstructivist inquiry strategy, committed to the attainment of participative environmental education objectives is suggested. The approach, referred to as an operation-environment instructional model emphasizes action research, supported by a series of other vital stages, as fundamental to the agenda for environmental learning.William W. Toili possesses both Bachelor and Master's Degrees in Education from Nairobi as well as a Master's Degree from the University of Leeds, UK. He is currently a lecturer in Environmental Education at Maseno University College.     

Designing a mixed performance measurement system for environmental supply chain management using evolutionary game theory and balanced scorecard: A case study of an auto industry supply chain

This paper proposes a mixed performance measurement system using a combination of evolutionary game theory and the balanced scorecard (BSC) in environmental supply chain management (ESCM) that measures and evaluates business operations using the four different perspectives of finance, customer, internal business process, and learning and growth. ESCM plays an important role in the supply chain which leads to the reduction, reuse and recycling of resources involved in both upstream and downstream activities. This paper presents guidance for practical managers in evaluating and measuring ESCM by developing a knowledge-based BSC and evolutionary game theory. The primary purpose of this paper is to apply the proposed method in a case study to one of Iran's biggest auto industry supply chain SAIPA Company. The results of this study indicate that the adoption of ESCM, in the absence of regulatory pressures and cost-saving measures is triggered by public pressures and its implementation is limited by organizational factors and strategic myopia.
