The oil industry along the Atlantic coast of Cameroon: Assessing impacts and possible solutions

While the oil industry along the Atlantic coast of Cameroon has made important contributions to the national economy, this has been accompanied with adverse environmental impacts. There has been significant pollution from oil drilling, refinery waste, oil spillage, gas and flaring. After discussing these impacts, this paper argues that prevailing regulations are inadequate and need overhauling. It proposes that cleaner production requires:

(i)

specific laws to protect dwellers in the neighbourhood of oil refineries, filling stations, service stations and pipelines;     

A mechanical pre-treatment process for the valorization of useful fractions from spent batteries

In this paper the authors propose a full-scale plant aimed to pre-treat spent batteries in order to obtain cleaned useful fractions (magnetic and non-magnetic metals, paper, plastic, a fine-sized material made of a metal-carbon mixture). The treating process was designed after having analyzed and tested a representative sample coming from the whole amount of spent batteries collected in 1 month by the public service in and around Turin. The analyses performed on the sample allowed the authors to determine its in-percentage composition in term of type of batteries: 60-70% b.w. (by weight) alkaline, 25-30% b.w. Zn-C and 5-10% b.w. other types. For each type, the composition in term of size (AAA or LR03; AA or LR6; C or LR14; D or LR20; 9 V or 6F22A; 4.5 V or 3R12A) has also been determined.The treatment for the recovery of secondary raw materials foresees the following phases:

-

separation of useful types/sizes of exhaust batteries to undergo further treatments by means of a first sieving process;

-

liberation of the single components taking advantage of a crushing operation;

-

separation of a fine-sized material (to subject to pyro or hydro metallurgic recovery) from a coarse-sized material (to send to secondary smelt foundries and incinerators) by means of a second sieving phase.

On the basis of the results obtained from the crushing/sieving laboratory tests and the chemical characterization, a full-scale plant able to treat about 76,000 t/y of spent batteries has been designed. The cost analysis performed on the proposed treatment plant has given back a unit pre-treatment cost equal to 3€ per ton of processed spent batteries.     

Linking carbon sequestration science with local sustainability: an integrated assessment approach

This paper introduces an integrated assessment (IA) approach for a Canada-China joint research project that linked forest carbon sequestration, forest resource management, and local sustainability enhancement. The purpose of the IA was to improve the measurement of carbon in different land uses and vegetation covers, as well as to direct decision makers to those land uses or options as an CO₂ emission reduction strategy while supporting rural sustainable development. In this connection, three questions are addressed in this paper:

1)

How will forestry carbon sequestration land use policies affect regional sustainability prospects in rural China?     

An Ecology of Prestige in New York City: Examining the Relationships Among Population Density,Socio-economic Status,Group Identity,and Residential Canopy Cover

Several social theories have been proposed to explain the uneven distribution of vegetation in urban residential areas: population density, social stratification, luxury effect, and ecology of prestige. We evaluate these theories using a combination of demographic and socio-economic predictors of vegetative cover on all residential lands in New York City. We use diverse data sources including the City’s property database, time-series demographic and socio-economic data from the US Census, and land cover data from the University of Vermont’s Spatial Analysis Lab (SAL). These data are analyzed using a multi-model inferential, spatial econometrics approach. We also examine the distribution of vegetation within distinct market categories using Claritas’ Potential Rating Index for Zipcode Markets (PRIZM?) database. These categories can be disaggregated, corresponding to the four social theories. We compare the econometric and categorical results for validation. Models associated with ecology of prestige theory are more effective for predicting the distribution of vegetation. This suggests that private, residential patterns of vegetation, reflecting the consumption of environmentally relevant goods and services, are associated with different lifestyles and lifestages. Further, our spatial and temporal analyses suggest that there are significant spatial and temporal dependencies that have theoretical and methodological implications for understanding urban ecological systems. These findings may have policy implications. Decision makers may need to consider how to most effectively reach different social groups in terms of messages and messengers in order to advance land management practices and achieve urban sustainability.     

Prevalence of Conservation Design in an Agriculture-Dominated Landscape: The Case of Northern Indiana

We examined the prevalence of residential development that occurs with consideration of the natural features of the site, known as conservation design, within county-level planning jurisdictions across Northern Indiana. Using data from telephone interviews with representatives of planning departments, jurisdictions were ranked based on reported use of conservation design. Three categories of use emerged from the data: no use, use of individual practices associated with conservation design, and integration of multiple conservation design practices. Qualitative data analysis revealed that conservation design practices were not being used widely and, when used, were often used to fulfill stormwater requirements. Statistical analysis, using data from interviews, spatial data sets, and the U.S. Census Bureau, identified several significant positive predictors of the levels of conservation design use including conversion of forest or agricultural land cover to urban uses and education levels in the jurisdiction. Many of the interviewees noted that agricultural land is perceived to meet open space needs within their counties. Given that agricultural land does not fully meet all ecosystem needs, education about the benefits of other types of open space is suggested.

New national parks for Scotland: coalitions in conflict over the allocation of planning powers in the Cairngorms

The introduction of national parks in areas where existing authorities have traditionally been responsible for developing policies, preparing plans and making decisions on development proposals, can be a threat to longstanding interests. This paper explores this problem by examining the struggle for control of planning in one of Scotland's first national parks, the Cairngorms. Recent research (McCarthy et al., 2002 McCarthy J Lloyd G Illsley B (2002) National parks in Scotland: balancing environment and economy Research briefing European Planning Studies 10 (5) pp. 665–670 [Web of Science ®] [Google Scholar]) has established the policy context for this investigation. Informed by research focusing on the consultation process which led to the establishment of the national park, this paper analyzes how alternative approaches to the allocation of planning powers were captured in competing storylines, around which polarized coalitions of interest formed. Opening such insights into the considerations that shape institutional design—a combination of contested problem framing and straightforward political struggles over the locus of regulatory power—starkly reveals the challenges to the new park authority as it seeks to establish consensus between conflicting interests.     

A comparative evaluation of the major pollution control programs in the United States and West Germany

In order to provide a more adequate means for the preservation and the enhancement of the environment, the United States and West Germany (the Federal Republic of Germany) have either created new institutions or altered existing agencies for the implementation of public policy. Along with these developments, a series of programs have been specifically designed to foster and maintain a quality environment. In this article, we examine the particular strategies employed in the implementation of environmental pollution control laws through the new or altered administrative arrangements in the two countries. The basic tools employed to implement environmental management strategies can be grouped as follows: traditional regulatory procedures, economic incentive concepts, information and volunteerism concepts, and government induced technological changes (USEPA 1976a). The following are examples of these techniques:

1. Traditional regulatory procedures
   1. laws
   2. ordinances
   3. permits
   4. zoning
2. Economic incentive concepts
   1. fines
   2. emission and effluent charges
   3. differential property rates
   4. subsidies
3. Information and volunteerism concepts
   1. labeling programs
   2. increased dissemination through mass media
4. Government-induced technological changes
   1. container controls
   2. subsidized recycling programs
   3. subsidized mass transportation systems

The specific applicability of any of these techniques varies with the particular type and degree of pollution control necessary. In some instances, a combination of these techniques may be appropriate. The degree of public acceptability and cost-effectiveness of the various techniques may vary as a result of regional differences. Furthermore, the success of all of these techniques is dependent upon a high degree of voluntary compliance. Through the examination of the various policy implementation strategies we should be able to appreciate the interrelationships between the different levels of government in pollution control efforts in the United States and West Germany.     

Regional impervious surface estimation: an urban heat island application

This paper describes a GIS-based estimation method that can be used to forecast future amounts of impervious surface as a mitigation measure for urban heat island effect in a metropolitan region. The method is unique because it employs a regression model that links the existing amount of impervious surface to population and employment at the census tract level. This approach provides a means to forecast future amounts of impervious surface based on projected population and employment. The method also includes a detailed analysis of high-resolution aerial photography to divide impervious surfaces into different categories. Subdividing impervious surfaces is necessary to evaluate potential urban heat island mitigation policies for different types of impervious surface. The analysis here shows that the impervious surface in the metropolitan Atlanta region will increase to 2638 km2 2. “The Albedo is defined as the hemispherical reflectivity averaged over the solar spectrum. A perfect reflector has a = 1, and a perfect absorber has a = 0” (Pomerantz et al. 1999 Pomerantz, M. 1999. Reflective surfaces for cooler buildings and cities. Philosophical magazine B, 79: 1457–1476. [Taylor & Francis Online], [Web of Science ®] [Google Scholar], p. 1458). View all notes in 2030, an increase of 45% from 2000. The most common type of impervious surface is dark-coloured pavement. Within this study area, the analyses showed that two-thirds of impervious surfaces are dark. Replacing dark pavement with light pavement materials, therefore, represents an important opportunity to mitigate the urban heat island effect in the Atlanta region.     

Where the Waters Divide: First Nations,Tainted Water and Environmental Justice in Canada

Abstract

We have survived Canada's assault on our identity and our rights … Our survival is a testament to our determination and will to survive as a people. We are prepared to participate in Canada's future—but only on the terms that we believe to be our rightful heritage.

Wallace Labillois, Council of Elders, Kingsclear, New Brunswick

This paper argues for a strengthening of the theoretical relationship between neo-liberalism and environmental justice. Empirical research involving First Nations communities in southwestern Ontario suggests that neo-liberal reforms introduced in the mid-1990s were particularly discriminatory against Canada's indigenous peoples, serving to exacerbate historical disparities in health, environment pollution, and well-being. In particular, under neo-liberal reform in Ontario, recognition of environmental injustices has become much more difficult for First Nations communities. Furthermore, this ‘new’ form of environmental governance has broadly reduced legitimate opportunities for First Nations to participate in environmental governance that affects their health and welfare. In short, this research supports a widening of the definition of environmental justice advocated by David Schlosberg and others (Environmental Politics, 13(3) (2004), pp. 517–540; Agyeman, Bullard and Evans 2003 Agyeman, J., Bullard, R. D. and Evans, B. 2003a. “Joined-up thinking: bringing together sustainability, environmental justice and equity”. In Just Sustainabilities: Development in an Unequal World, Edited by: Agyeman, J., Bullard, R. D. and Evans, B. Cambridge, MA: MIT Press.  [Google Scholar]; Akwesasne Task Force on the Environment, Research Advisory committee 1997; Di Chiro 1998 Di Chiro, Giovanna. 1998. “Environmental Justice from the Grassroots: Reflections on History, Gender and Expertise”. In The Struggle for Ecological Democracy: Environmental Justice Movements in the United States, Edited by: Faber, D. NY: Guilford.  [Google Scholar]) if we are to understand the subtle, complex and multiple ways that this new form of environmental governance is particularly harmful to marginalized groups, such as First Nations in Canada.     

Economic, social, and environmental sustainability in development theory and urban planning practice

In ten years, more than half the world's population will be living in cities. The United Nations (UN) has stated that this will threaten cities with social conflict, environmental degradation and the collapse of basic services. The economic, social, and environmental planning practices of societies embodying urban sustainability have been proposed as antidotes to these negative urban trends. Urban sustainability is a doctrine with diverse origins. The author believes that the alternative models of cultural development in Curitiba, Brazil, Kerala, India, and Nayarit, Mexico embody the integration and interlinkage of economic, social, and environmental sustainability. Curitiba has become a more livable city by building an efficient intra-urban bus system, expanding urban green space, and meeting the basic needs of the urban poor. Kerala has attained social harmony by emphasizing equitable resource distribution rather than consumption, by restraining reproduction, and by attacking divisions of race, caste, religion, and gender. Nayarit has sought to balance development with the environment by framing a nature-friendly development plan that protects natural systems from urban development and that involves the public in the development process. A detailed examination of these alternative cultural development models reveals a myriad of possible means by which economic, social, and environmental sustainability might be advanced in practice. The author concludes that while these examples from the developing world cannot be directly translated to cities in the developed world, they do indicate in a general sense the imaginative policies that any society must foster if it is to achieve urban sustainability.     

Extra- and intra-European Union exchanges of recovered materials and products

On the basis of the data Comext from Eurostat, this paper presents 2001 data on the main exchanges (flows) intra-European Union (EU) and with the rest of the world (extra-EU), by countries (for the main countries which are concerned), tonnage and value, by categories of recovered materials and products. A synoptic table is established, the results are summarized, and initial comments are provided. Moreover the evolution from 1995 to 2001 is discussed.The second part of the paper examines what these data tell us:

* whether they are consistent with the main theories of international trade, and which factors explain these exchanges,

* what is the extent of foreign trade of recovered products and materials,

* to what extent the EU appears as ‘an economic entity’,

* and possible effects of the enlargement of the EU.

The Stakeholder Preference for Best Management Practices in the Three Gorges Reservoir Region

A qualitative analysis of in-depth interviews with 92 farmers and 42 policy managers in Wuxi County, the Three Gorges Reservoir Region, was conducted to identify stakeholder preferences for alternative best management practices (BMPs) and to determine the factors that affect their acceptance. Policy manager support for most of the practices was relatively stronger than support by farmers, except for the grade stabilization structure (GSS), hillside ditch (HD) and constructed wetland alternative, owing to their perceptions of soil benefits, economic advantages and environmental advantages. Farmers opposed those practices that occupied cultivated lands or changed the conventional planting methods, such as field border, conservation tillage (CT) and contour buffer strips. They tended to accept the BMPs with off-farm pollution reduction, such as GSS, riparian forest buffer and HD, and the BMPs associated with soil benefits, such as nutrient management and Terrace. The result that almost all respondents did not accept CT differed from reports in the existing literature. There is a significant correlation between the acceptance of some BMPs and the townships where the farmers lived (P ≤ 0.05). The environmental conditions and social factors would affect farmer support for BMPs, including local soil conditions, farming methods, economic income, education level and age. The economic advantages of the BMPs were the main motivation for farmers to accept the practices. Furthermore, intensive education efforts, financial incentives or economic subsidies may promote the adoption of the BMPs in our study area.     

Australian Local Government Attempts to Deliver Beneficial Environmental Outcomes

Abstract

This paper presents the results of a national project investigating Australian local government (LG) attempts to deliver beneficial environmental outcomes. It briefly describes the extensive environmental planning, management and protection roles played by Australian LGs. It notes that these roles are poorly documented within the academic literature, and makes a case for fundamental research to better understand LGs and their work from the inside. It describes this project's use of grounded theory methods in gathering and analysing 34 case studies of Australian LG environmental initiatives. The inside perspectives represented by the papers show that Australian LG environmental work:

• extends beyond its statutory requirements;

• is novel and creative;

• endures by balancing ecological, social and economic values;

• demonstrates different patterns depending on its planning, management or protection focus; and

• usually involves environmental strategists with long-term, passionate commitments to local environmental values.

     

Breathtaking Clarity,Delicious Ambiguity

Abstract

A new institutional architecture is emerging in Wales to govern sustainable development. The National Assembly for Wales (hereafter referred to as the ‘Welsh Assembly’)1 ¹The National Assembly for Wales is the legal entity and title given to the devolved body in Wales. ‘Welsh Assembly Government’ is the term used by the current administration. has a statutory duty to promote sustainable development in the exercise of all its functions; its response has been to design a set of political and organizational arrangements to manage this policy area, and to prepare a Scheme that sets out how it proposes to discharge this duty. Devolved government in Wales has also been the catalyst for the emergence of collaborative relationships and partnerships between different sectors and interests. The Welsh Assembly and the Welsh Local Government Association have published a Compact jointly committing them to promote sustainable development; national non-governmental organizations such as Oxfam and the World Wide Fund for Nature have set up Welsh agencies; local government sustainable development coordinators have formed a national network; a national Sustainable Development Forum has been created; and the Welsh Assembly has taken the lead in establishing a European network of countries interested in sharing best practice on sustainable development. A new Wales-specific structure and system is materializing and the test now is how far this will be effective in delivering sustainable development policies and solutions at local and national levels. This paper examines the challenges in managing sustainable development, and the potential for success of this new governance system, drawing on recent research undertaken by the author on behalf of the Joseph Rowntree Foundation. The examination is set in the context of different theories of governance, and sustainable development is conceptualized as a ‘wicked issue’—one that cannot be resolved by organizations and agencies acting autonomously, but rather needs concerted focus and action across all sectors.     

Advocates for environmental justice: the role of the champion in public participation implementation

That segment of the community I would say is just in general pretty disenfranchised. We found that if you want participation you have to go to them. I mean there are days when you just need to go knock on the door.

Brownfields developer in a poor urban neighbourhood

This article considers the role that champions play as advocates for socioeconomically disadvantaged community member involvement in environmental management decision-making. Six case studies of brownfields redevelopment projects located in poor urban neighbourhoods are examined. Analysis of these case studies reveals how champion behaviour, which has typically been studied only in the context of technological innovation, is enacted in public participation efforts in the service of environmental justice. The study finds that champions who emerge in these settings lead the development and implementation of non-standard public participation process innovations.     

Environmental Ethics and Biomimetic Ethics: Nature as Object of Ethics and Nature as Source of Ethics

While the contemporary biomimicry movement is associated primarily with the idea of taking Nature as model for technological innovation, it also contains a normative or ethical principle—Nature as measure—that may be treated in relative isolation from the better known principle of Nature as model. Drawing on discussions of the principle of Nature as measure put forward by Benyus (Biomimicry: innovation inspired by nature, Harper Perennial, New York, 1997) and Jackson (Consulting the genius of place: an ecological approach to a new agriculture, Counterpoint, Berkeley, 2010, Nature as measure: the selected essays of Wes Jackson, Counterpoint, Berkeley, 2011), while at the same time situating these discussions in relation to contemporary debates in the philosophy of biomimicry (Mathews in Organ Environ 24(4): 364–387, 2011; Dicks in Philos Technol, doi: 10.1007/s13347-015-0210-2, 2015; Blok and Gremmen in J Agric Environ Ethics 29(2):203–217, 2016), the aim of this paper is to explore the relation between the principle of Nature as measure and environmental ethics. This leads to the argument that mainstream formulations of environmental ethics share the common trait of seeing our ethical relation to Nature as primarily involving duties to protect, preserve, or conserve various values in Nature, and that, in doing so, they problematically either overlook or dismiss as anthropocentric the possibility that Nature may provide measures, understood in terms of ecological standards, against which our own practices, or at least some of them, may be judged—a way of thinking I call “biomimetic ethics”. The practical consequences of this argument are significant. Whereas mainstream environmental ethics has been applied above all to such issues as wilderness preservation, natural resource management, and animal rights and welfare, biomimetic ethics is applicable rather to the question of how we produce, use, and consume things, and, as such, may potentially provide the basic ethical framework required to underpin the transition to a circular, bio-based, solar economy.     

Planning for global environmental change in Bangkok's informal settlements

Government agencies in cities across Asia recognise that municipalities must take steps to adapt to projected climate changes if people and places are to be kept above water. This paper focuses on planning for climate change in Bangkok because it ranks among the top 10 port cities vulnerable to climate change related flooding. It is also understood that the most devastating impacts of climate change will be suffered by the city's most vulnerable residents: the poor. Not only do impoverished people occupy physically vulnerable space, such as riverbanks, but they are also the least equipped to recover from the disruption of their livelihoods.

Several scholars have identified “institutional traps” that prevent the Thai government from successfully aiding poor and marginalised flood victims in the past. These include poor coordination, lack of monitoring and evaluation, rigidity, crisis management and elite capture. Lebel, Manuta, and Garden (2011, 56) Lebel, L., J.B. Manuta, and P. Garden. 2011. “Institutional Traps and Vulnerability to Changes in Climate and Flood Regimes in Thailand.” Regional Environmental Change 11 (1): 45–58.[Crossref], [Web of Science ®] , [Google Scholar] pose the crucial question: “How have individuals – from local community leaders through to national level politicians and bureaucrats – successfully influenced policy and programmes to avoid institutional traps and improve adaptive capacities to climate change?”

In this paper, we begin to address this question through examining emergent methods of “community based adaptation” and reviewing case studies of adaptation action from other vulnerable communities in the Global South. These lessons – such as overcoming institutional rigidity and avoiding elite capture – are important for Bangkok and other cities in the Global South that face many different challenges by global environmental change.     

An Empirical Evaluation of Private Landowner Participation in Voluntary Forest Conservation Programs

The use of voluntary programs targeting resource conservation on private land has become increasingly prevalent in environmental policy. Voluntary programs potentially offer significant benefits over regulatory and market-based approaches. This article examines the factors affecting landowner participation in voluntary forest conservation programs using a combination of parcel-level GIS and remotely sensed data and semi-structured interviews of landowners in Monroe County, Indiana. A logistic regression model is applied to determine the probability of participation based on landowner education, membership in other non-forest voluntary programs, dominant land use activity, parcel size, distance from urban center, land resource portfolios, and forest cover. Both land use activity and the spatial configuration of a landholder’s resource portfolio are found to be statistically significant with important implications for the design and implementation of voluntary programs.
