In order to further ensure that the 2030 Agenda for Sustainable Development is to be implemented and the action measures of all countries are consistent, the United Nations has put forward a set of indicators to monitor and evaluate the progress of global sustainable development. This set of evaluation indicators is aimed for global and regional progress. An important feature of the evaluation indicators is that they are internationally comparable, but due to the large differences in the levels of sustainable development among countries, this framework of evaluation indicators has a disadvantage that it does not apply to tracking the progress of sustainable development at the national level. This paper focuses on the analysis of specific issues in the application of the global sustainable development indicators framework to meet the goals and targets of the UN and builds a system of evaluation indicators to assess the progress of sustainable development at the national level in China, and offers a perspective to assess China’s progress as well.  相似文献

BackgroundEvidence on health effects of ultrafine particles (UFP) is still limited as they are usually not monitored routinely. The few epidemiological studies on UFP and (cause-specific) mortality so far have reported inconsistent results.ObjectivesThe main objective of the UFIREG project was to investigate the short-term associations between UFP and fine particulate matter (PM) < 2.5 μm (PM2.5) and daily (cause-specific) mortality in five European Cities. We also examined the effects of PM < 10 μm (PM10) and coarse particles (PM2.5–10).MethodsUFP (20–100 nm), PM and meteorological data were measured in Dresden and Augsburg (Germany), Prague (Czech Republic), Ljubljana (Slovenia) and Chernivtsi (Ukraine). Daily counts of natural and cardio-respiratory mortality were collected for all five cities. Depending on data availability, the following study periods were chosen: Augsburg and Dresden 2011–2012, Ljubljana and Prague 2012–2013, Chernivtsi 2013–March 2014. The associations between air pollutants and health outcomes were assessed using confounder-adjusted Poisson regression models examining single (lag 0–lag 5) and cumulative lags (lag 0–1, lag 2–5, and lag 0–5). City-specific estimates were pooled using meta-analyses methods.ResultsResults indicated a delayed and prolonged association between UFP and respiratory mortality (9.9% [95%-confidence interval: − 6.3%; 28.8%] increase in association with a 6-day average increase of 2750 particles/cm3 (average interquartile range across all cities)). Cardiovascular mortality increased by 3.0% [− 2.7%; 9.1%] and 4.1% [0.4%; 8.0%] in association with a 12.4 μg/m3 and 4.7 μg/m3 increase in the PM2.5- and PM2.5–10-averages of lag 2–5.ConclusionsWe observed positive but not statistically significant associations between prolonged exposures to UFP and respiratory mortality, which were independent of particle mass exposures. Further multi-centre studies are needed investigating several years to produce more precise estimates on health effects of UFP.  相似文献

An obvious need for an updated and comprehensive study prompted this investigation of the complex of environmental costs resulting from the nation’s dependence on pesticides. Included in this assessment of an estimated $10 billion in environmental and societal damages are analyses of: pesticide impacts on public health; livestock and livestock product losses; increased control expenses resulting from pesticide-related destruction of natural enemies and from the development of pesticide resistance in pests; crop pollination problems and honeybee losses; crop and crop product losses; bird, fish, and other wildlife losses; and governmental expenditures to reduce the environmental and social costs of the recommended application of pesticides.The major economic and environmental losses due to the application of pesticides in the USA were: public health, $1.1 billion year−1; pesticide resistance in pests, $1.5 billion; crop losses caused by pesticides, $1.4 billion; bird losses due to pesticides, $2.2 billion; and groundwater contamination, $2.0 billion.*Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue.  相似文献

By 2012, Hammarby Sjöstad, a former large industrial harbor area in southern Stockholm, Sweden, will be a fully developed residential district containing approximately 11,000 apartments and accommodating 35,000 people. The transformation of the area began in 1996, and the development soon became renowned for its ambitious environmental program, inspired by Agenda 21 (United Nations in Rio declaration on environment and development. United Nations Department of Economic and Social Affairs (DESA), Rio de Janeiro, 1992) and the Sydney 2000 Olympics in Australia (Newman in Landsc Urban Plan 44:219–226, 1999). Using results based on literature reviews, in-depth interviews, discussions with focus groups, and quantitative data, this paper attempts to gain insight into how the environmental program influenced the planning and performance of the district with regard to sustainable urban development. In doing so, three important conclusions were maintained that could be valuable for similar projects concerning the planning and development of sustainable urban districts. First, the environmental program proved vital to the development process of Hammarby Sjöstad, specifically in its drive to create a sustainable urban district. When planning on improving the sustainability of future districts, such a program should be introduced and integrated earlier in the planning stage of the district. Second, the metabolic flows of Hammarby Sjöstad were reduced as a result of the integrated system—the Hammarby Model—of Hammarby Sjöstad. In order to reduce the metabolic flows in future urban districts even further, it is important to facilitate the integration of technical innovations into existing integrated systems. Third, this case study showed that there was a loss of valid and credible data related to the aims and goals of the environmental program of Hammarby Sjöstad. In future urban districts, it is of the utmost importance to include a clear structure of the assessment process in the environmental program, which would ensure the quality of gathered data and facilitate the development of even better sustainable urban districts in the future.  相似文献

The Rio+20 summit of the United Nations in Brazil in 2012 committed governments to formulate a set of sustainable development goals (SDGs) that would be integrated into the Millennium Development Goals (MDGs) following its expiration in 2015. This decision has pushed sustainable development agenda into the limelight of development once again. Meanwhile, we note that the development agenda of many developing countries has been dominated by neoliberal orientation driven by market reforms, social inequality, and a move towards enhancing the economic competitiveness of the supply side of the economy. In this paper, we discuss the relationship between neoliberal economic agenda and sustainable development. We do so by examining how neoliberal policies of privatisation, trade liberalisation and reduction in governments spending stand to affect the attainment of sustainable development ideals and their implications on the post-2015 Sustainable Development Goals. The paper then suggests that relying solely on the mechanisms of the market in governing and allocating environmental resources is necessarily insufficient and problematic and therefore calls for a new approach—one which goes beyond just recognising the interdependency among social, environmental and economic goals and places issues of equity and addressing unfavourable power relations at the centre of interventions aimed at achieving the ideals of sustainable development.  相似文献

Since the United Nations Conference on Environment and Development in 1992 in Rio de Janeiro, sustainable development became an important issue. Sustainable development often focuses on a single sector or parameter such as tourism, energy supply, water management, different aspects of nature conservation, or economy. In this paper, we provide a comprehensive picture of the development of a region since the Middle Ages and discuss whether this development can be evaluated as socially, economically and ecologically sustainable. We carried out a combined qualitative–quantitative assessment where we use quantitative data and indicators when available, as well as literature sources and expert knowledge from the region for a qualitative assessment. We judge that generally a sustainable development in the Allgäu region can be found, although also some critical points and contentious issues exist. An overall good economic and income situation for most people, the good ecological conditions and rich biodiversity, the relatively well-established social structure, as well as the identity of the people with the region and comparatively low social discrepancy, can be positively stated. In contrast, different actual and future threats exist such as new or planned infrastructure, increasing traffic or tourism activities in certain areas that degrade habitats and reduce species richness, intensification of agriculture in certain areas, but also abandonment of agriculture in other areas, loss of traditions and customs, and declining numbers of smallholders. The objective for the region would be to minimise these negative impacts and reinforce positive trends to assure the sustainable development of the Allgäu.  相似文献

As corporations seek to appeal to environmentally conscious stakeholders, advertisements containing environmental claims have become increasingly prominent. A corporation's desire for an enhanced corporate reputation, combined with lenient environmental advertising regulation, has created the perfect environment for corporations to use—and misuse—environmental claims, resulting in “greenwashing.” Defined as the act of disseminating disinformation to consumers regarding the environmental practices of a company or the environmental benefits of a product or service, greenwashing occurs around the world. This study is a cross-national content analysis of 247 print ads from 84 issues of mainstream magazines from the United States and United Kingdom. Three-fourths (75%) of the ads analyzed contained one or more aspects of greenwashing. Firms advertising in US magazines were significantly more likely to employ misleading/deceptive environmental claims than UK firms and magazines. These findings suggest that without increased environmental advertisement regulation, greenwashing will persist as a disingenuous means for corporate reputation enhancement.  相似文献

There are hardly any critical discussions of sustainable development indicator sets designed for use at the national level. This article aims at rectifying this omission in critical academic research by contributing to the discourse on environmental sustainability with an assessment of the indicator set used for the measurement of sustainable development in Germany. It will evaluate to what extent the sustainable development concept is reflected in the structure of the strategy and analyse in how far fundamental environmental issues are covered by the indicator set. The discussion will show that the environmental dimension of the sustainability concept is not sufficiently integrated in the German National Sustainable Development Strategy. Although the strategy??s indicator set contains a range of environmental indicators, gaps in the German indicator set become apparent when contrasted with important issues of sustainability. It will be concluded that the environmental dimension of the sustainable development concept is not the recurrent theme in either the strategy or the indicator set.  相似文献

This article discusses the perspectives of two First Nations of Canada, northeastern British Columbia’s West Moberly First Nations, Halfway River First Nation, and Treaty 8 Tribal Council, regarding the impacts of industrial resource extraction in lands critical to their traditional cultures and subsistence activities. This collaborative project interviewed First Nation government officials and staff as well as community members and Elders, which created a complex picture of physical impacts of industrial development as well as psychological and cultural concerns. In addition, we briefly explore the impacts of First Nations being required to constantly participate in consultative processes, such as environmental assessment, designed to predict potential impacts. We conclude that recognizing and meaningfully addressing all types of impacts that First Nations experience is critical, both for ensuring environmental justice for indigenous peoples and for recognizing that some land and resources must remain for indigenous peoples to continue to practice their traditional culture. We note, as well, that if there is no room amidst industrial resource extraction activities for indigenous peoples, there is also no room for other environmentally critical values such as healthy ecosystems.  相似文献

China-Africa development cooperation in the rural sector has received an increased attention by researchers and policy-makers given the advantages and disadvantages of China’s contribution to the local economy. However, there is a lack of more reliable and nuanced findings to provide greater insights into the major issues concerning rural development and resource use. This paper aims to position land tenure and foreign investments linkages as a new research angle for understanding the role of land in sustainable resource use and investments. The paper provides a brief overview of China-Africa cooperation in rural development especially concerning agriculture to illustrate the neglect of critical land and resource use issues in policy and practice. The paper briefly discusses the ongoing land tenure reforms in Africa and the policy gaps to be filled through further research. It also discusses how China’s own development model, especially concerning land tenure reform, shares similar trajectories with Africa, which has important implications for the effectiveness of Chinese investments in African land. The paper concludes that there is an urgent need for lesson learning among Chinese and African policy-makers and investors towards tailoring development cooperation to more appropriate land tenure systems for sustainable resource use to the mutual benefit of Chinese and African stakeholders.  相似文献

The 17 Sustainable Development Goals announced by the United Nations are important guides for the development processes of developing countries. However, achieving all of these goals is only possible if the goals are consistent with each other. It has been observed in the literature that possible contradictions between these goals are ignored. Therefore, the main purpose of this study is to investigate whether two sustainable development goals (SDGs) of the UN are contradictory or supporting each other in low-income countries. These SDGs are “Good Health and Well-Being” (SDG3) and “Partnerships for the Goals” (SDG17). For this purpose, the role of globalization and democracy in life expectancy is empirically investigated in 16 low-income countries over the period 1970–2017. While globalization has been used as an indicator of the partnership between countries, democracy has been used as an indicator of accountability and cooperation between governments and societies. According to estimations of the continuous-updated fully modified (CUP-FM) and bias-adjusted ordinary least squares (BA-OLS), globalization and its subcomponents such as economic, social, and political globalization affect life expectancy positively. Democracy also increases life expectancy in those countries. The GDP per capita is also used as a control variable. Our results show that a higher level of per capita income is positively associated with higher levels of life expectancy. In conclusion, no contradiction was found between SDG3 and SDG17 in those countries. Achieving a healthier society requires economic, social, and political integration between governments and societies.

BackgroundAn association between serum levels of two perfluoroalkyl substances (PFAS) and delayed age at menarche was reported in a cross-sectional study of adolescents. Because perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) have half-lives of years, growth dilution and the development of a new route of excretion (menstruation) could account for some or all of the reported association.ObjectivesTo assess how much of the epidemiologic association between PFAS and delayed menarche can be explained by the correlation of growth and maturation with PFAS body burden.MethodsWe developed a Monte Carlo (MC) physiologically-based pharmacokinetic (PBPK) model of PFAS to simulate plasma PFAS levels in a hypothetical female population aged 2 to 20 years old. Realistic distributions of physiological parameters as well as timing of growth spurts and menarche were incorporated in the model. The association between PFAS level and delayed menarche in the simulated data was compared with the reported association.ResultsThe prevalence of menarche, distributions of age-dependent physiological parameters, and quartiles of serum PFAS concentrations in the simulated subjects were comparable to those reported in the epidemiologic study. The delay of menarche in days per natural log increase in PFAS concentrations in the simulated data were about one third as large as the observed values.ConclusionThe reported relationship between PFAS and age at menarche appears to be at least partly explained by pharmacokinetics rather than a toxic effect of these substances.  相似文献

ABSTRACT

Limited research to date has qualitatively explored the perceptions members of the public who are not environmental activists hold of environmentalists. Therefore a qualitative survey was conducted with 89 US residents aged 21–53 (Mage?=?32.74, SDage?=?7.89) to obtain an in-depth understanding of how non-activists within the public perceive environmentalists. Data obtained were analyzed using thematic analysis and demonstrated that non-activist perceptions of environmentalists contained both positive and negative components. Environmentalists were seen to value nature and to be actively involved in bringing about positive environmental change (positive component), yet were also viewed as aggressive in their behaviors and stubborn in their beliefs (negative component). Further still, it was found that environmentalists were more likely to be perceived positively when they engaged in individual-level, private sphere behaviors (such as recycling), and negatively when they engaged in collective-level, public sphere behaviors (such as protesting). These findings not only challenge the assumption that members of the public typically evaluate environmentalists negatively, they also outline why some individuals may fail to identify as an environmentalist and engage in pro-environmental behavior. Furthermore, they also provide some insight as to why some environmentalists find it difficult to advocate for system change that results from collective action within the public sphere.  相似文献

The aim of research was to assess the changes of annual radial increment of Scots pine forests in the vicinity of intensive and moderate industrial pollution of “Achema” factory producing mineral fertilizers. Our results indicate that the radial growth of the pine tree can be divided into three different periods: growth promotion, growth inhibition and growth recovery. Low levels of nitrogen emissions were beneficial for tree growth: the radial increment in the intensive and moderate pollution zones increased by 15–25% and 10%, respectively compared to control. During the growth inhibition period, the total annual industrial emission was 37–40 kt, and 40–45% radial growth loss was observed for the closest and 15–20% for the most distant stands. The radial growth decrease slowed down and the recovery of damaged stands began in 1990–1992 then air pollution was considerably reduced. The rate of forest recovery was high for the most damaged stands: their radial growth was close to control in 2000–2011.  相似文献

Rapid environmental change in vulnerable destinations has stimulated a new form of travel termed “last chance tourism” (LCT). Studies have examined the risks of LCT, while leaving potential opportunities within this new tourism market largely underexplored. Results of survey (n?=?399) research in Jasper National Park, Canada reveal that a LCT motivation influences decisions to visit this iconic Canadian destination, and suggest that this motivation is linked to a desire to learn about the impacts of climate change on the Athabasca Glacier. Findings suggest there may be short to medium term opportunities associated with LCT, including promoting climate change ambassadorship through management interventions. This paper discusses a range of possible education, interpretive, and outreach activities that might be employed at LCT destinations. It outlines the relative merits (or what we refer to as “uneasy benefits”) of promoting the glacier and other LCT destinations within a protected areas management and climate change adaptation context.  相似文献

The present study analysed media discourse on a gold mining controversy in Greece. Social actors shaped a pro-mining and an anti-mining coalition. The “village of Gaul” was a discursive resource used to depict conflict and it could denote either “resistance,” for anti-mining advocates, or “anarchy,” for pro-mining advocates. The same actor could be found to perform both the role of a powerful majority as well as the role of a repressed minority, which engaged varying scales of reference. Discursive positioning allowed for a switching among majority and minority roles. Each camp attempted to transform incalculable hazards into calculable risks and this was accompanied by a discursive appropriation of the past and the future of the study area. Social divide seems to have advanced discursive positioning of coalitions in a spiral-logic of interactionist confrontation at the cost of losing any common ground. Implications for environmental communication and environmental governance are discussed.  相似文献
