Wind energy and natural ventilation potential of a wind catcher in Yazd – Iran (a long-term measurement)

When designing energy efficient buildings it is useful to study existing climate—responsive building typologies. The wind towers or wind-catchers of Yazd city in Iran are typical examples of such a typology. Although many previous studies have investigated the performance of various types of wind catcher systems, studies based on a long-term real-life measurement can be rarely found. In this study a long-term whole year monitoring campaign on an existing full scale four sided wind catcher in Yazd was carried out in 2014–2015. Three prevailing wind directions were identified and the measured on-site wind speeds were used to estimate the wind induced natural ventilation potential of the tower. A shaft/tower airflow performance index was developed. The monitoring results were compared to the ASHRAE Standard 62:2001 ventilation rate requirement. Results show that the total ventilation rate of the wind tower surpasses the ASHRAE Standard requirements. Furthermore it shows that the shafts are exposed to the prevailing wind directions perform better. For more effective natural ventilation a wind tower with adaptable openings/shafts are proposed.     

Objectively best or most acceptable? Expert and lay knowledge in Swedish wind power permit processes

This article analyses legal aspects of the Swedish wind power development, theoretically based on how different types of knowledge are represented in legal contexts, mainly in the courts. A sample of appealed wind power permits is analysed, a handful of relevant informants are interviewed – including two judges in the Land and Environment Court and the appeal court – and the legal setting is analysed. Of key interest here is the interplay between expert and lay statements in the court cases, which here is related to the concepts of calculating and communicative rationalities that are developed in the planning literature. The results indicate that the juridification – which takes place as a permit issue is appealed in the judiciary system – supports the calculating rationality more than the communicative, and that the plaintiffs often attempt to adapt in how they shape their argumentation.     

“It's easy to throw rocks at a corporation”: wind energy development and distributive justice in Canada

In places like Canada, fast-paced wind turbine development combined with policy that limits local decision-making power has resulted in strong opposition to specific projects. Some studies suggest that anti-wind sentiment is tied to inadequate financial benefits – especially sharing at the local level. Thus, ideas of distributive economic justice have received traction, particularly in the form of praise for community-based development models. This paper reports on the findings from a mixed-methods study concerning preferred distributive justice elements in rural communities in Ontario (technocratic-based model) and Nova Scotia (community-based model) living with turbines. Residents’ perceptions of economic benefits are nuanced, but unlike other studies, this empirical work shows that both the fair distribution and the amount of local benefits are important predictors of project support. Yet, concerns around the fair distribution of benefits dominate in a regression on the adequacy of those benefits. A variety of interview and survey findings further point to the strength of traditional, profit-sharing community-based models for distributing benefits, but also more novel ideas including lowered electricity bills and tax rebates in areas home to turbines.     

From social ‘acceptance’ to social ‘acceptability’ of wind energy projects: towards a territorial perspective

Social acceptance is central in many debates surrounding energy projects. Wind energy, in particular, has been described as a ‘learning laboratory’ in terms of social acceptance of energy projects. It has given way to a socio-technical paradox: the social dimension has become a factor of equal importance to technology in the wind farms implementation. Based on a literature review concerned with the social acceptance of wind energy, the paper seeks to demonstrate both the richness and the limits of the key concepts that inform the ongoing work of scholars. By doing so, we intend to emphasise the complex processes underneath in order to then elaborate a conceptual definition of social acceptability. Various modulations and limits that characterise current thinking are thus underlined. We then propose a grid analysis relying on a territorial perspective. It is structured around three levels that connect micro-social, meso-political and macro-economic processes.     

Locating ‘power’ in wind power planning processes: the (not so) influential role of local objectors

There have been conflicting accounts of the role and influence of local opposition within planning application outcomes for wind power developments. There is an expanding literature that considers public responses to proposed renewable energy developments and much of this suggests that public opposition is a key factor in the slow growth in renewable energy capacity. However, this paper will show that local opposition groups' power over such planning processes is very limited, and in fact extends only so far as delaying an outcome. Through a thematic content analysis of objection letters to one particular proposed wind power development, the key issues raised in connection with the development will be highlighted. Subsequently, these issues will be compared with those discussed in the official report of the planning appeals process, and it will be shown that the concerns of local objectors had little influence over the eventual verdict.     

Effects of observability and complexity on farmers’ adoption of environmental practices

The ability of both regulators and farmers themselves to monitor the impact of environmental practices may be an issue with nonpoint source pollution. Effects that can be perceived via direct sensory evidence provide information at low cost. Results from a survey of livestock farmers suggest that a practice that has more obvious effects on water quality, manure application setbacks, is more likely to be adopted than a more complicated one with less visible effects, manure testing. Farmers’ perceptions of the profitability of the two practices were similar. The importance of observability and complexity has implications for educational programs.     

Analysis of Scavengers’ Activities and Recycling in Some Cities of Nigeria

The state of solid waste recycling by scavengers in Onitsha, a heavily commercial city in Anambra State, and some other urban areas such as Nsukka, Enugu, and Port Harcourt was analyzed. Data were obtained through interviews of scavengers who deal with recyclables. Although the activities of scavengers are sub-optimal, they can have a great impact on Nigerian economy with respect to resource conservation, creation of job opportunities, and reduction of the magnitude of waste disposal problems. A cost analysis is presented to compare the different forms of recycling utilized by municipal solid waste management. It is shown that a well-planned recycling program with recycling and composting would result in 18.6% savings in waste management costs and 57.7% in landfill avoidance costs. However, if the compost materials are not recycled, the corresponding savings in cost become 8.6% and 28.6%, respectively. The option with the lowest cost involves encouraging individual households to separate at the source their recyclables, which are bought by scavengers. This results in 78.0% savings in waste management cost and 79.5% landfill avoidance cost. A low-cost approach aimed at the integration of scavenging activities into conventional solid waste management is presented.     

Criminalization of “galamsey” and livelihoods in Ghana: Limits and consequences

The fact that the artisanal and small-scale mining (ASM) sector in Ghana is driven largely by poverty means that the sector is a major source of livelihood for people in mining communities across the country. However, given the various social and environmental problems associated with the ASM sector, there is now an emerging consensus that the formalization of the sector would not only allow for these associated problems to be addressed but also ensures that the sector contributes to sustainable development and safeguard the livelihood of local communities. While a large body of extant literature has examined the challenges and opportunities facing the process of formalization, the question of the criminalization of the sector and its consequences for local livelihood has received only limited attention. Drawing from primary data collected during fieldwork in Ghana, this study examined the livelihood implications of the ban on galamsey in the Tarkwa-Nsuaem Municipality in South-Western Ghana from the perspectives of local communities and other key stakeholders. The study reveals that the ban on galamsey has imposed significant socio-economic hardships on the people and appears to be entrenching poverty rather than sustainable development. The study considers the theoretical and practical implications of the findings for sustainable livelihood enhancement in developing countries.     

Just and Sustainable? Examining the Rhetoric and Potential Realities of UK Food Security

The dominant discourse in 20th century UK food and agricultural policies of a liberal, free trade agenda was modified at the turn of the 21st to embrace ecological sustainability and “food security.” The latter term has a long international history; the relationship between issues of technical production and equality of distributional access are also much debated. The paper examines shifts in UK policy discourse in the context of international research, policy, and initiatives to promote food security, and highlights the implications for social justice in and through the food system.     

Stakeholders’ Perceptions of GM Technology in West Africa: Assessing the Responses of Policymakers and Scientists in Ghana and Nigeria

The perception of two key stakeholders such as policymakers and scientists on genetic modification (GM) technology was examined in Ghana and Nigeria using semi-structured interviews. A total sample of 20 policymakers (16 at ministries and 4 at parliament/cabinet) and 58 scientists (43 at research institutes and 15 at universities) participated at the interviews. This study revealed respondents perspectives on potential benefits and risks of GM technology, status and development of biosafety regulatory frameworks, role of science and technology innovation in agricultural development, intellectual property right and related issues. The study also shed some light on a possible influence of the European Union and United States in the development and potential adoption of GM technology. More importantly, the article suggests that most respondents including policymakers believe that GM technology has great potential to solve part of agricultural problems in both countries. But, lack of appropriate regulatory framework, lack of trained personnel, weak institutions and poor equipped laboratory among others represent a significant challenge in introducing GM technology in this part of Africa.     

Coexistence of Plants and Coexistence of Farmers: Is an Individual Choice Possible?

The introduction of genetically modified organisms (GMOs) in Europe has been characterized by controversy. In 2002, the European Union introduced the concept of “coexistence” as a compromise solution that, through the establishment of science-based technical measures, should allow the market to operate freely while reducing policy conflicts on GMOs. However, the concept remains highly contested and the technical measures difficult to apply. This paper presents qualitative research on the conceptualization and implementation of the coexistence framework in two regions of Spain (Catalonia and Aragon), where 42% and 55% of maize was GM in 2006, respectively. In this context, the concept of coexistence and its proposed implementation both fail to resolve previous conflicts and actually work to generate new ones through the individualization of choice and impacts. Considerations of the social conditions in which the technology and the management measures are implemented were not taken into account. This resulted in the promotion of biotechnological agriculture over other alternatives.     

Ryder’s Painism and His Criticism of Utilitarianism

As a member of the British Oxford Group, psychologist Richard Ryder marked the beginning of the modern animal rights and animal welfare movement in the seventies. By introducing the concept “speciesism.” Ryder contributed importantly to the expansion of this movement. Surprisingly little attention has been paid to Ryder’s moral theory, “painism”, that aims to resolve the conflict between the two predominant rival theories in animal ethics, the deontological of Tom Regan and the utilitarian of Peter Singer. First, this paper examines the kernel and historical sources of Ryder’s painist theory, linking it to the work of John Rawls and Jean-Jacques Rousseau. Second, it examines Ryder’s critique of utilitarianism. It is argued that his critique of Singer’s use of the word “sentience” is unconvincing and that his critique of utilitarian aggregation as not taking a full account of the metaphysical separateness of persons, has already been countered and dealt with. Finally this paper looks at some of the counterintuitive implications of Ryder’s theory and argues that utilitarianism might have more resources for dealing with its own alleged counterintuitive implications than Ryder acknowledges.     

Application of Zoning and “Limits of Acceptable Change” to Manage Snorkelling Tourism

Zoning and applying Limits of Acceptable Change (LAC) are two promising strategies for managing tourism in Marine Protected Areas (MPAs). Typically, these management strategies require the collection and integration of ecological and socioeconomic data. This problem is illustrated by a case study of Koh Chang National Marine Park, Thailand. Biophysical surveys assessed coral communities in the MPA to derive indices of reef diversity and vulnerability. Social surveys assessed visitor perceptions and satisfaction with conditions encountered on snorkelling tours. Notably, increased coral mortality caused a significant decrease in visitor satisfaction. The two studies were integrated to prescribe zoning and “Limits of Acceptable Change” (LAC). As a biophysical indicator, the data suggest a LAC value of 0.35 for the coral mortality index. As a social indicator, the data suggest that a significant fraction of visitors would find a LAC value of under 30 snorkellers per site as acceptable. The draft zoning plan prescribed four different types of zones: (I) a Conservation Zone with no access apart from monitoring or research; (II) Tourism Zones with high tourism intensities at less vulnerable reefs; (III) Ecotourism zones with a social LAC standard of <30 snorkellers per site, and (IV) General Use Zones to meet local artisanal fishery needs. This study illustrates how ecological and socioeconomic field studies in MPAs can be integrated to craft zoning plans addressing multiple objectives.     

The green dividend of urban biking? Evidence of improved community and sustainable development

As the cost of car ownership has skyrocketed, urban biking has experienced the largest share increase of any transportation mode, rising by 40% between the years 2000 and 2014. Growing attention is being paid to the potential local economic development impacts of urban neighbourhoods becoming more bike-friendly. It is now a green economic development strategy in cities as diverse as Chicago, New York City, Portland, and San Francisco to increase bicycling as a transportation mode. This paper reports the results of a survey of 2032 responses from faculty, staff, and students of a car-dependent, downtown university. We use a mixed methods approach, including data from the American Community Survey, to support our arguments and to inform potential savings and economic benefit calculations that can be achieved from bicycle infrastructure investments and anticipated redistributed spending patterns. We argue that urban biking results in a green dividend that promotes local community development and more importantly results in zero carbon emissions.     

Management of mountain areas in Norway and the persistence of local–national conflicts

We have investigated why conflicts linked to the distribution of power between governments and actors at the national and local levels concerning environmental management of mountain areas in Norway persist despite political intentions to strengthen local powers. We seek to explain this by analysing changes in policies, institutional frameworks, and regional contexts, and the local perceptions of these changes. Paradoxically, the national government's power has apparently been strengthened by new sectoral regulations and more stringent enforcement of the existing ones, increases in the number and extent of protected areas, and failures to act on intentions to devolve power. An additional factor spurring conflicts is the increased importance of tourism to mountain communities. To become more relevant to policies and development in mountain areas, future studies on multilevel governance must address multilevel politics, entire mountain areas, and the context of their development, rather than focusing on minor projects and protected areas.     

What Is Source Reduction? A Critique and Comparative Analysis of Polish and American Students

/ Source reduction is recognized as the preferred form of waste management, but its definition is ambiguous. This study proposes four underlying dimensions of the source reduction concept. Source reduction is foremost a preventive activity that reduces the number or extent of environmental impacts. Second, source reduction can prevent both resource consumption and pollution generation impacts. Third, source reduction may be viewed as both a producer and consumer activity. Lastly, it may include frugal and more efficient activities. In surveys exploring these fourdimensions, Polish and American university students evaluated whether 20 activities were examples of source reduction. The American students gave higher ratings to preventive activities over adaptive activities. The Polish students most prominently rated efficient over frugal activities. Factor analysis indicated that both samples identified a group of consumer-based resource conservation activities, with the American students recognizing a cluster of recycling activities. In a separate ranking of environmental protection priorities, the Polish students endorsed pollution prevention, whereas the American students favored both efficient and frugal resource conservation. These findings suggest that the conceptualization of source reduction varies according to contextual factors and that prevention is still an obscure environmental management theme. KEY WORDS: Source reduction; Pollution prevention; Resource conservation; Frugality; Poland     

Forecast of the demand and supply plan of China’s uranium resources till 2030

This paper’s purpose is to predict China’s uranium resources demand from 2016 to 2030 based on experimental modeling. In addition, we discuss the future supply structure of China’s uranium resources by analyzing the domestic and foreign supply capacity of China’s uranium resources. According the forecast results, Chinese uranium resource demand will reach 21385 tU in 2030 under a medium scenario. Due to the poor endowment of uranium resources, China’s domestic uranium production will increase slowly. It can be calculated that the total demand of uranium resources in China during 2016–2030 will be 216581 tU, the cumulative production of domestic production will be 37900 tU, the overseas production will be 41950 tU, and the international market purchases will be 130574 tU. Hence, the cumulative degree of dependence on foreign resources is approximately 80%. China’s foreign dependence on uranium will be greater than for oil, and the situation will become extremely serious. Therefore, we put forward several suggestions to ensure the supply of China’s uranium resources: (1) strengthening mineral exploration and increasing domestic production, (2) actively operating the “going out” strategy, (3) enhancing the enterprise competition ability, and (4) establishing uranium resource reserves. By these means, China could efficiently guarantee the domestic uranium resource security and respond to the competition of India’s uranium resources demand increased.     

Some pitfalls of ‘manstream’ environmental theory and practice

Summary Radical environmentalists consider the environmental crisis to be ultimately one of culture and character. However, in analyses and strategies for social transformation, non-feminist greens have generally accepted the Patriarchal conception of human motivation, which is based on a rational, impersonal (read Masculine) model of Man. Thus, it is implicitly assumed that the motivations underlying the environmental crisis are greed or self-interest (deemed rational motives in Western Patriarchal culture). Owing to this male-centred perspective on human nature, green strategies have ultimately relied on an appeal to reason. This, at least, has failed relative to the accelerating pace of environmental destruction.It is argued that a focus on the abuse of power leads to a more useful analysis of the causes of human oppression and environmental exploitation. The abuse of power can be understood as an attempt to overcompensate for unmet emotional needs (e. f. for love, recognition, and a sense of belonging) through an excessive drive for gratification in other dimensions of life. In Patriarchal thought, emotional needs are largely denied, being non-rational and non-masculine, and hence have also been largely ignored in social policy. This realisation suggests new strategies.Dr Janis Birkeland was an attorney, architect and planner San Francisco, USA, and now teaches at the Department of Architecture, University of Tasmania.

Mesoscale survey of western and northwestern Irish lakes – Spatial and aestival patterns in trophic status and phytoplankton community structure

Inland water bodies are considered as integrated parts of the landscape and the monitoring of water quality and aquatic resources need to be addressed on a regional basis for optimal assessment and management. In this study, a simple stratified sampling scheme was applied to a mesoscale survey of western and northwestern Irish lakes, which was carried out to identify, based on the distribution patterns of phytoplankton biomass, potential associations between lake trophic state and land cover attributes. Phytoplankton community analysis was also performed to determine whether taxa associations reflected meteorology-linked aestival succession or specific spatial distributions. The assessment was based on the typology of hydrogeomorphological and land cover attributes of river catchments through ArcGIS analysis. Sampling was carried out in 50 lakes and during a 15-week period in summer 2009. Results showed a general longitudinal gradient in the trophic status of the lakes sampled, with a greater frequency of mesotrophic lakes in the eastern part of the study area where land cover is dominated by agricultural surfaces. Significant relationships (p < 0.010) were found between chlorophyll-a concentration and the proportion of river catchment surface covered by agriculture land and wetlands, findings which might be considered further as proxies for developing an eutrophication risk index. Multivariate analysis of phytoplankton community data clustered the sampled lakes into three assemblages, with ordination along axis 1 being significantly correlated to time and temperature (p < 0.006). There was greater frequency of occurrence of diatoms in lakes from cluster III (Kruskal–Wallis, p < 0.05, H = 6.34, df = 2, n = 49), concomitant to lower chlorophyll-a concentrations, lake surface temperatures and Secchi depths, reflecting meteorological conditions dominated by precipitations. Those results support the potential of mesoscale surveys to assess water quality variables and detect environmental patterns at regional scales.     

Waste of organic and conventional meat and dairy products—A case study from Swedish retail

Many retailers take initiatives to reduce food waste, which can lead to enhanced sustainability, including reduced environmental impacts and cost savings. Another common environmental strategy in retail management is to increase the range of organic products. This study examined if organic food products have a higher level of waste, which thereby risk to counteract the environmental ambitions behind offering these products. The study also examined to what degree differences in waste level could be explained by turnover, shelf-life and wholesale pack size. In the study, six Swedish supermarkets provided data on all articles sold or wasted in the deli, meat, dairy and cheese departments during 2010 and 2011. 24 organic products were compared to their conventional counterparts; 22 of these had higher waste levels (from 1.5 to 29 times higher). Differences in wastage were also compared across departments; in all four departments, organic products as a group had higher waste percentage at all four departments. There was a negative correlation between the total mass sold of a product and the percentage waste. Also, longer shelf-life was associated with decreased waste, but only for products with low turnover. The systematic problem of retail food waste – particularly of organic products and other products with a low turnover – may be mitigated by increasing turnover, by stocking products with longer shelf-life or by decreasing the ordered volume (e.g. through decreased wholesale pack sizes).
