A Review of Environmental Sociology and the Sociology of Natural Resources： Insights for the Development of Environmental Sociology in China

Environmental sociology and the sociology of natural resources are two key subdisciplines of the sociological study on the interactions between nature and human society. Previous discussion on the relationships of these two fields has largely focused on their distinctions and synthesis in western （particularly American） academia. Environmental sociology emerged as an important sociological subdiscipline in China in the early 1990s and is under vigorous disciplinary construction at present. By contrast, the sociology of natural resources is still a novel term for most Chinese researchers. This article provides a systematic review of recent literature on the relationships between environmental and natural resource sociologies, which should provide important implications for the further development of environmental sociology in China.     

Overall Planning of Development of Urban-Rural Areas:A Policy Mechanism for Urban-Rural Coordinated Growth

While analyzing overall planning and coordinated development of urban-rural areas, this paper shows that overall planning for the development of urban-rural areas is a requirement for the best use of productive forces. It means the setting up of a policy mechanism for coordinated growth. Recognizing this, the government should set up a way to lead and manage a unified program to increase service and decrease controlling administration power, while safeguarding and fulfilling the farmers' ownership to the means of production.     

2014, The “year without a summer” in Italy: news media coverage and implications for the climate change debate

In 2014, there was virtually no summer in northern and central-southern Italy. Storm after storm battered the peninsula, triggering floods and landslides from Veneto to Puglia. We studied the coverage of “the year without a summer” in Italy by analyzing the content of 171 news articles from two influential online newspapers. Our software-based analysis enabled us to observe that the two newspapers hardly ever mentioned climate change in their coverage of the weather anomaly that affected Italy in the summer of 2014. This type of coverage is in line with climate science, according to which there is no evidence of a climate change-related influence on summer precipitation patterns in Southern Europe—whereas such influence has been documented for northern Europe. We compared our results with a recent paper, which documented that the same online dailies chose to represent the particularly hot summer of 2012 in Italy as a direct consequence of climate change. We corroborated this comparison also on the basis of a preliminary analysis we performed on the media coverage of the exceptionally hot and arid summer of 2015 in Italy.     

Recent Changes in Land-Use in the Pambala–Chilaw Lagoon Complex (Sri Lanka) Investigated Using Remote Sensing and GIS: Conservation of Mangroves vs. Development of Shrimp Farming

Shrimp aquaculture is currently one of the major threats to mangroves, their destruction causing both environmental and social problems. This study investigated the mangrove area in the Pambala–Chilaw Lagoon complex (07°30 N, 079°49 E) in Sri Lanka. Using air-borne remote sensing, a land-use map was constructed in a geographical information system of the study area and pond managers were interviewed about the functioning of their shrimp farms. Based on fieldwork during the four years after taking the aerial photographs, an updated GIS-based land-use map was constructed and compared the original situation. This revealed that shrimp farms had expanded with by 25 ha in four years, mainly at the expense of mangrove forest (approx. 13 ha) and coconut plantations (approx. 11 ha). Official documents from the World Conservation Union advise conservation of the undisturbed habitats in Pambala, but this study's observations do not corroborate an eventuation of this. Other authors reported political patronage as the main cause of this adverse situation. Since the shrimp industry depends on various ecological services provided by the mangrove ecosystem in order to maintain production (cf. ecological footprint concept) the mangrove destruction is counter-productive and these observations are therefore alarming for the aquaculturists as well. The low ratio (2.6 : 1) of remaining mangrove to shrimp pond area suggests that the industry may experience severe problems, particularly as mangrove areas continue to be reclaimed for aquaculture or other land uses, unless drastic measures are taken.     

Development of an educational model for sustainability science: challenges in the Mind–Skills–Knowledge education at Ibaraki University

Modern society confronts multiple sustainability challenges, including population growth, resources limitations, and a deteriorating environment. As a response, sustainability science education plays a major role in developing human capacity to manage these issues. This paper proposes the concept of “sustainability science education across Mind–Skills–Knowledge” as well as the competencies to be acquired and its pedagogy. This paper evaluates the effectiveness of such an educational system and its method of implementation using the example of the Graduate Program on Sustainability Science (GPSS), which was started at Ibaraki University in 2009.     

Participatory incremental slum upgrading towards sustainability: an assessment of slum dwellers’ willingness and ability to pay for utility services

The concept of participatory slum upgrading has received attention in the conventional literature because it ensures and promotes the sustainability of slum-upgrading programmes. In participatory slum-upgrading programmes, slum dwellers are treated as partners, instead of recipients of the services that are provided to mitigate their deprivations. The concept thrives on the willingness and ability of slum dwellers to pay for the services. The ability of slum dwellers to pay for services, unlike their willingness to pay, has received limited research attentions. Therefore, the purpose of this study was to assess the willingness and ability of residents of a slum settlement in Kumasi in Ghana to pay for utility services. Semi-structured interview schedules were used to gather primary data from a total of 276 households. The survey data were supplemented with data from key informant interviews and focus group discussions. The results show that almost nine out of every ten households were willing to pay for water and electricity services, if these services would be supplied to them directly by the state providers. The exploitation of the residents by unregulated utility services providers partly explains their willingness to pay for the utility services. These service providers charged almost 14 times the official tariffs. The results further show that all the households who were willing to pay were also capable of paying for the services without compromising their ability to afford other life essentials. The study concludes that slum regularisation policies, programmes and projects could be designed to be incremental and participatory by making the slum dwellers, partners and drivers of the upgrading process.

Sediment integrative assessment of the Bay of Cádiz (Spain): An ecotoxicological and chemical approach

This study consisted of the sediment toxicity assessment of the Bay of Cádiz based on two endpoints: growth inhibition for Cylindrotheca closterium (benthic microalgae) and fecundity inhibition for Tisbe battagliai (harpacticoid copepod). A new methodology to eliminate (but not as storage technique) the autochthonous biota present in the sediment samples by immersing them in liquid nitrogen (? 196 °C) was also assessed. Sediment toxicity data showed different toxicity levels for both organisms. In general, T. battagliai was more sensitive; however a good correlation (r = 0.75; p  < 0.05) between sediment toxicity results for both species was found. Data in pore water (pH, redox potential, and toxicity for microalgae and copepod) and sediment (pH, redox potential, organic carbon, and metal concentrations) demonstrated that ultra-freezing did not alter sample characteristics; thus, this technique can be adopted as a pre-treatment in whole-sediment toxicity tests in order to avoid misleading results due to presence of autochthonous biota. Multivariate statistical analysis such as cluster and principal component analysis using chemical and ecotoxicological data were employed. Silt and organic matter percentage and lead concentration were found to be the factors that explain about 77% of sediment toxicity in the Bay of Cádiz. Assay methodology determined in this study for both assayed species is considered adequate to be used in sediment toxicity monitoring programs. Results obtained using both species show that the Bay of Cádiz can be considered a moderately polluted zone.     

Understanding American and Korean Students’ Support for Pro-environmental Tax Policy: The Application of the Value–Belief–Norm Theory of Environmentalism

By using the value–belief–norm theory of environmentalism, this study investigates American and Korean college students’ support for pro-environmental tax policy as a way to address global climate change. The results indicate that environmental concern and the perceived severity of climate change were significant predictors of one's tax policy support. Perceived individual responsibility for addressing climate change mediated the relationship between environmental beliefs (i.e. environmental concern and perceived severity) and tax policy support for Koreans. Such relationship was not observed among Americans. This study also examines whether political ideology functions as a predictor of tax policy support. For Americans, political ideology was a significant factor in predicting one's tax policy support and that it remained significant even after the inclusion of more proximal predictors—environmental concern and perceived severity. For Koreans, however, political ideology was not a significant factor. Theoretical and practical implications are discussed.     

The contribution of the sciences,technology and innovation to sustainable development: the application of sustainability science from the perspective of UNESCO’s experience

The contribution of scientific knowledge and innovation to sustainability is demonstrated. Theory, discoveries, programmes and activities in both the natural as well as social sciences fields have greatly helped with the environmental, economic and social challenges of the past and current centuries, especially in the past 50 years or so. Nowadays, we increasingly realize the intimate link between science and society, and the need not only for science to inform policy but also to address requests by governments and the multiple stakeholders confronted with the challenge to achieve sustainable development. Current barriers to how science is conceived and related education is delivered hamper true interdisciplinarity, and the emerging field of sustainability science attempts inter alia to clarify how ‘a new generation of science’ can be designed so as to promote more integrated thinking to tackle complex societal issues. At the international level, and more specifically in the context of the United Nations, the practice of science has always entailed the need to solve problems such as climate change, ozone depletion, disaster risk, lack of food security, biodiversity loss, social instability and ineffective governance—to cite a few. In this regard, science in an intergovernmental context is by definition science that has to assist with the struggle for sustainability. Yet, a higher level of integration and cross-fertilization among disciplines as well as of participation among concerned stakeholders in the design and implementation of science-based programmes and activities carried out by the United Nations (and, in this article, the specific case of its Educational, Scientific and Cultural Organization—UNESCO—is presented) seems to be needed. The debate on sustainability science carried out in the academic circle and the experience of UNESCO in this area can be mutually supportive in further elucidating how, practically, the approach of sustainability science can enhance the achievement of sustainable development at multiple scales.     

The flow/fund model of Conga: exploring the anatomy of environmental conflicts at the Andes–Amazon commodity frontier

This paper aims to contribute toward improved understanding of complex ecological distribution conflicts at the commodity frontiers, where increasing metabolism in industrial societies is leading to increased environmental destruction in resource-rich countries throughout the world. The focus of this paper is the Conga gold mine project in northern Peru, where there have been violent clashes between the Minera Yanacocha mining company and the local population, represented mainly by campesinos that live in the highlands of the Andes–Amazon region. We do this by using the flow/fund model developed by Georgescu-Roegen and extended by Giampietro and Mayumi, to help us trace the anatomy of this conflict, using simplified representations of the central economic processes involved: gold mining and milk production. By complementing the concept of Ricardian land—an indestructible fund—with the concept of land materials, which is susceptible to qualitative change, and therefore can be either a fund or a flow element of the economic process, we illustrate that the gold extraction process, which treats this land material as a flow, stands in conflict with the milk production process, at least in part, because that process is using these land materials as a fund, i.e., in order to make production possible. The paper employs the concept of environmental valuation triadics, developed by Farrell, in order to explore how the boundaries—physical frontiers and temporal durations—of a specified economic process are related to flow/fund element identities. We conclude with some reflections on potential future applications for the methods employed and on the implications of our analytical results.     

Seeing the Wind (Farm): Applying Q-methodology to Understand the Public’s Reception of the Visuals Around a Wind Farm Development

This research investigates the reception of the visual representations of a wind farm (WF) development by local stakeholders. Using non-verbal Qmethodology, residents of Lesvos’ island, Greece, sort images according to how these images represented their opinion about the proposed Aegean Link WF project. We found three opinion types. The “Risk Averter” type is focused on the various risks of constructing and operating the Aegean Link wind development. The “Green Developer” type believes that the renewable energy project will benefit both their local community and the environment. The “Realist” type defers to expert knowledge to make decisions about project outcomes and is sceptical of media bias. While the former two types seem to form their visual opinions based on whether they are in favour or against (respectively) of the WF development, the Realist opinion is rather guided by carefully considering whether the visual stimuli are representative of the project’s actual characteristics.     

Contributions for the use of qualitative indicators: an analysis of Itaipu Power Plant’s Sustainability Program

An integrated approach based on multiple indicators and individual and combinational evaluation methods is proposed to evaluate water scarcity. Four evaluation methods are employed, and their results are joined through three combination methods in order to obtain a consistent evaluation. This iterative-correction approach has been applied to Yunnan Province in China for water scarcity evaluation. The results demonstrate the capability of the iterative-correction framework to provide insightful analyses of water scarcity. Diqing Tibetan Autonomous Prefecture (Diqing) and Nujiang Li Autonomous Prefecture (Nujiang) ranked 1st and 2nd, indicating the best situation for water scarcity evaluation, while Yuxi and Zhaotong ranked 15th and 16th, indicating the worst situation. Two types of major water scarcities were observed in Yunnan Province. One was a typical representative of lack of water quality in the central part of Yunnan, and the other was a typical engineering type in the western part of Yunnan. The water scarcity has been found to arise from non-judicious water use, rapid urbanization and lack of protective measures for water resources. Therefore, it is necessary to conduct more water conservancy projects in future to alleviate the water scarcity issue.     

Shifting maize cultivation and secondary vegetation in the Southern Yucatán: successional forest impacts of temporal intensification

Shifting cultivation around the Calakmul Biosphere Reserve of Mexico, part of the Mesoamerican Biological Corridor, appears to be intensifying temporally through reductions in crop–fallow cycles, with potential impacts on species diversity in the regenerating forest patches surrounding the reserve. This paper documents the temporal intensity of shifting maize cultivation in the region and links it to the species diversity found in secondary vegetation of different ages following different crop–fallow cycles. It finds that younger secondary growth, which is increasing under intensification, has less diversity in species composition. Simultaneously, the concentration of cultivation practices appears to foster more patches in older and more species-diverse vegetation. The implications for the preservation of the region’s forest remain uncertain, however, given the spatial concentration of open lands along two key axes, one which dissects the reserve.     

The Empirical Analysis of the Impacts of Income Distribution Gap on Consumption Demand: Based on the Statistic Data of Chinese Urban Residents in 2000–2010

Abstract

This paper analyzes the impact of income distribution gap on consumption demand from a theoretical view, and draws the conclusion that there is an inverse relationship between income distribution gap and consumption demand. Then, the paper finds that the existing widening income distribution gap in China has a negative impact on consumption demand, but this is not the key factor for the insufficient consumption demand because of the low level of per capital income. At last, it suggests that governments should improve the income level of entire residents and adjust income distribution structure simultaneously.
