Importance of information on tillage practices in the modelling of environmental processes and in the use of environmental indicators

Tillage has been and will always be integral to crop production. Tillage can result in the degradation of soil, water, and air quality. Of all farm management practices, tillage may have the greatest impact on the environment. A wide variety of tillage equipment, practices and systems are available to farmers, providing opportunities to enhance environmental performance. These opportunities have made tillage a popular focus of environmental policies and programs such as environmental indicators for agriculture. This paper provides a very brief examination of the role of tillage in crop production, its effect on biophysical processes and, therefore, its impact on the environment. Models of biophysical processes are briefly examined to demonstrate the importance of tillage relative to other farm management practices and to demonstrate the detail of tillage data that these models can demand. The focus of this paper is an examination of the use of information on tillage in Canada's agri-environmental indicators initiative, National Agri-environmental Health Analysis and Reporting Program (NAHARP). Information on tillage is required for several of the indicators in NAHARP. The type of data used, its source, and its quality are discussed. Recommendations regarding the collection of tillage data and use of tillage information are presented.     

Back to nature: new urban policy and environmental governance in Canada's capital

Drawing on a growing literature on the integration of environmental discourses into urban development schemes, this paper charts the urban development of LeBreton Flats, in Ottawa, Ontario, Canada. An industrial neighbourhood expropriated as part of a post-war urban renewal project, LeBreton Flats is being redeveloped in line with green, mixed-use urban planning principles. The paper investigates how national narratives are intertwined within urban development practices and argues that historically and geographically embedded expressions of national nature first used to justify post-war expropriation are being adapted as part of urban neo-liberal naturalised practices of central-city redevelopment.     

Proximal exposure of public schools and students to major roadways: a nationwide US survey

This study addresses the effect of urban planning and road development on the health risk of students attending schools near major roadways. The proximity of public schools and students was quantified to Interstate, US and state highways in nine large Metropolitan Statistical Areas (MSA) of the USA. In total among the surveyed schools and students, over 30% fell within 400 m of a major roadway and over 10% were within 100 m. For some MSAs almost half of the student population attended schools near (≤400m) major roadways, resulting in a potentially increased risk for asthma and other chronic respiratory problems, especially in schools representing the urban fringe locale. It was concluded that proximity of major roadways should be an important factor in considering sites for new schools and developing policies for reducing the exposure in existing schools. The findings provide an important reference point for coordinating future urban development, transportation and environmental policies.

Southwest climate gap: poverty and environmental justice in the US Southwest

This article examines the “climate gap” in the Southwest US (Arizona and New Mexico), referring to the “disproportionate and unequal implications of climate change and climate change mitigation” for “people of color and the poor” [Shonkoff, S.B., et al., 2011. The climate gap: environmental health and equity implications of climate change mitigation policies in California. Climatic Change, 109 (Suppl. 1), S485–S503]. The climate and poverty relationship is examined using multi-scaled analysis across three indicators of climate vulnerability, focusing on connections to health, food, and energy during the period 2010–2012. We provide an overview of climate-related social vulnerability in the Southwest based on available federal, state, and county-level census data. We then summarise the results from a stakeholder workshop and in-depth interviews about climate vulnerabilities with social service providers in southern Arizona. We identify a significant Southwest climate gap based on census data and interview findings about climate vulnerability especially relating to high levels of poverty, health disparities, and increasing costs for energy, water, and food. We find that grassroots and community organisations have mobilised to respond to climate and social vulnerability, yet resources for mitigation and adaptation are insufficient given the high level of need. Confronting a changing climate that is projected to be hotter, drier, and with the potential to reach new thresholds, we suggest that more research needs to be done to understand the social and spatial characteristics of climate risk and how low-income populations embody and experience climate risk, and adapt to a changing climate.     

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.

Blocking pipelines,unsettling environmental justice: from rights of nature to responsibility to territory

ABSTRACT

Indigenous peoples are among the most affected by environmental injustices globally, however environmental justice theory has not yet meaningfully addressed decolonisation and the resistance of Indigenous communities against extractivism in the settler-colonial context. This paper suggests that informing environmental justice through decolonial analysis and decolonising practices can help transcend the Western ontological roots of environmental justice theories and inform a more radical and emancipatory environmental justice. The Unist’ot’en Resistance and Action Camp blocking pipelines in northwestern British Columbia, Canada, their “Reimagined Free Prior and Informed Consent protocol” and the Delgamuukw case are described to discuss limitations of the state and legal framework for accommodating a decolonial and transformative environmental justice. A decolonial analysis informed by these two moments of Wet’sewet’ten history suggests limits and adaptations to the trivalent EJ framework based on recognition, participation and distribution. It is argued that a decolonising and transformative approach to environmental justice must be based on self-governing authority, relational ontologies of nature and epistemic justice and the unsettling of power through the assertion of responsibility and care through direct action. This discussion is placed in the context of the expansion of the concept of ecological rights, for example through the enshrining of the “Rights of Nature” in the constitutions of countries such as Bolivia and Ecuador, to highlight the Inherent tensions in the translation of Indigenous cosmo-visions into legal systems based on universalist values.     

Life cycle indicators for monitoring the environmental performance of European waste management

As widely recognised by EU legislation, Life Cycle Thinking (LCT) is a viable approach to support sound waste management choices. In this context, the Institute for Environment and Sustainability (IES) of the European Commission Joint Research Centre (JRC) has lead the development of macro-level, life cycle based waste management indicators to quantify and monitor the potential environmental impacts, benefits, and improvements associated with the management of a number of selected waste streams generated and treated in Europe.The waste management indicators developed make use of a combination of macro statistical waste management data combined with emissions/resource life cycle data for the different elements of the waste treatment chain. Indicators were initially calculated for the entire European Union (EU-27) and for Germany, covering several waste streams and a broad range of environmental impact categories.An indicator developed for a given waste stream captures the potential environmental impact associated with the generation and management of that waste stream. The entire waste management chain is considered, i.e. from generation to final treatment/disposal. Therefore, system boundaries for the selected waste streams include also the treatment or recycling of secondary waste (e.g. bottom ash from the incineration of household waste), and secondary products (e.g. recovered paper), as well as energy recovery.The experiences from the development of these life cycle based waste management indicators suggest that more detailed and quality-assured waste statistics are needed, especially covering the many different treatment operations and options. Also, it would be beneficial if waste statistics had a higher disaggregation level of waste categories, as well as more detailed information about waste composition. A further development of the indicators should include an increased number of waste streams, as well as calculation of the results for all Member States.     

Beyond savanna: An evolutionary and environmental psychology approach to behavioral effects of nature scenery in green advertising

Evolutionary psychology has been proposed as an analytic framework for the behavioral effects of landscapes displayed in advertising. In this study, an evolutionary and environmental psychology approach is used to analyze affective reactions to advertising depicting specific natural environments or urban scenes, both prominent ingredients of contemporary advertising imagery. The experimental field study exposed 750 participants at random to one advert of a set of 13 experimental green energy advertisements, each displaying a different biome. Six basic emotional responses (pleasure, arousal, happiness, freedom, safety, and interest) as well as attitude toward the ad and brand attitude were assessed subsequently. Anova and structural equation analysis were used for data analysis. Results of the study confirm the leading opinion on generalized more positive behavioral effects toward visual stimuli representing nature scenes with biospheric contents as opposed to pictures of urban environments or desert settings. In line with earlier empirical research, further findings do not support the hypothesis on an innate preference for savanna landscapes in adults but confirm preferences for images of lush green landscapes with water and familiar biomes. Overall results give significant support to the application of environmental and evolutionary psychology to advertising.     

Empirical research in environmental psychology: Past, present, and future

Have research interests in environmental psychology changed over the years? If so, in which direction? What can we learn from the past to direct future research? To answer these questions, empirical studies published in Environment & Behavior (E&B) and in Journal of Environmental Psychology (JEP), from their foundation to 2005, were reviewed. The articles were classified in relation to the following criteria: mode of human–environment transaction, research topic, type of setting and function of places, socio-demographic characteristics and environmental role of people, mode of presentation of the setting, sampling procedure, and source of data. Results showed both variations through the years and differences between the journals. The main research topics can be identified as the study of the residential environment, environmental cognition, observation of actual behaviour in the environment, and concern for the ecological value of the global environment. Trends in research interests showed a stable interest in the analysis of the built environment, a more place-specific approach in the beginning, strongly anchored in observational studies, and a central concern for sustainability and conservation of the environment in recent years. With respect to journals, the central role attributed to psychology by JEP, and the stronger participation by designers and planners in E&B, are reflected in the emphases given to the different modes of human–environment transaction. Trends in research interests help address the strengths and weaknesses of the discipline, thus suggesting future directions of inquiry.     

Developing and applying an index of environmental integrity for the US Mid-Atlantic region

Environmental conditions in the Mid-Atlantic region of United States are presently being documented in a series of reports that use 'environmental report cards' to summarize the condition of individual natural resources (e.g. estuaries, streams, forests, and landscapes) over the entire region and within major subregions. An 'index of environmental integrity' (IEI) approach has been developed and is illustrated using the information content of these report cards to evaluate the overall condition throughout the region. The IEI approach is a four-step process: (1) select individual components for the index, (2) calculate subindex values for each of the individual components, (3) aggregate the subindex values into the overall index, and (4) interpretation of index values. The IEI approach was illustrated by applying to the Mid-Atlantic estuaries and wadable streams in the Mid-Atlantic Highlands. Because the IEI approach is new, application should not be made without considering issues such as evaluation of the selection of the indicators, weighting scheme, uncertainties, and appropriate way to interpret the values.     

Balancing environmental and industry sustainability: A case study of the US gold mining industry

Mandatory insurance requirements and/or mitigation fees (royalties) for mining companies may help reduce environmental risk exposure for the federal government. Mining is examined since the Environmental Protection Agency (EPA) Toxic Release Inventory reveals that this sector produces more hazardous waste than any other industrial sector. Although uncommon, environmental expense can exceed hundreds of millions of dollars per development. Of particular concern is the potential for mines to become unfunded Superfund sites. Monte Carlo simulation of risk exposure is used to establish a plausible range of unfunded federal liabilities associated with cyanide-leach gold mining. A model is developed to assess these costs and their impact on both the federal budget and corporate profitability (i.e., industry sustainability), particularly if such costs are borne by offending firms.     

Effectiveness of self-identified and self-reported environmental regulations for industry: The case of stormwater runoff in the US

US environmental controls for industry include numerous regulations that rely on the regulated community to self-identify, monitor, report, or complete other requirements on their own recognizance. These include state- and federal-issued general permits for stormwater discharges associated with industrial activities, effective in 1992, with known incomplete compliance by 2004. Results demonstrate highly incomplete compliance with variation in effectiveness among studied states and urbanized regions. Texas and Oklahoma, administered by US EPA during the research period, have attained higher compliance rates than California, administered by a state agency, or Florida, also administered by US EPA. Specific program designs and implementation strategies employed by states are evaluated for impacts on states' compliance effectiveness.
