Three parallel lines of inquiry regarding individuals' support for the environment have developed within the environmental social sciences. These include individuals' concern for the environment, research on private sphere pro-environmental behaviour (PEB), i.e. household actions seeking to improve the environment (e.g. buying better light bulbs), and more recently, ecological and carbon footprints. Researchers have noted that the correlates of this third form of support for the environment are not necessarily the same as the predictors of the first two forms. Using Canadian survey data, this study examines the relationships among, and predictors of, all three forms. Evidence that there is not a link between private sphere PEB and household carbon footprints, and that measures of socio-economic status (education and income) have different effects on different types of support for the environment, invites a discussion of whether environmental social scientists are really counting what counts. 相似文献

Metallic, masonry, and other solid debris that may be contaminated with hazardous chemicals litter numerous hazardous waste sites in the United States. Polychlorinated biphenyls (PCBs), pesticides, lead or other metals are some of the contaminants of concern. In some cases, cleanup standards have been established (e.g., 10 μg PCBs/100 cm2 for surfaces to which humans may be frequently exposed). Decontaminated debris could be either returned to the site as “clean” fill or, in the case of metallic debris, sold to a metal smelter. This project involves the development and demonstration of a technology specifically for per forming on-site decontamination of debris. Both bench-scale and pilot-scale versions of a debris washing system (DWS) have been designed, constructed, and demonstrated. The DWS entails the application of an aqueous solution during a high-pressure spray cycle, followed by turbulent wash and rinse cycles. The aqueous cleaning solution is recovered and reconditioned for reuse concurrently with the debris-cleaning process, which minimizes the quantity of process water required to clean the debris. 相似文献

Large-scale hog operations have generated intense conflict in rural communities in North America, and more recently in Alberta, Canada. The structure and process of public involvement processes for intensive hog operations influences how well the core issues of concern are addressed by public officials and pork producer proponents. This study reports interview findings from 43 key players in intensive hog operation controversies across four cases in Alberta, and summarizes four inter-related areas of the public participation processes that affect levels of trust among stakeholders, thereby altering the perceived fairness and the balance of power: (1) the timing of the public participation process; (2) information sharing; (3) accessibility of the process; and (4) accountability of public institutions and policies. Recent changes to the regulations of intensive livestock operations will unlikely address core issues of conflict without incorporating the above elements of democratic public involvement processes. 相似文献

Sustainable development requires the promulgation of guidelines for urban planning which consider the effects of the built environment on water resources. In this context, our paper focuses on the effects of urban development on the quantity and quality of rainwater which infiltrates into the soil on its way to recharge the aquifer. The paper includes: identification of the state of knowledge regarding the effect of urban development on runoff and infiltration; a case study-estimation of the effect of certain patterns of urban development in an Israeli neighbourhood,together with an option for mitigating them by relatively simple and inexpensive means; presentation of the components of urban planning which influence runoff and infiltration; and proposals for continuing research in this area which has been relatively neglected until recently. 相似文献

Organotin compounds have been widely used as antifouling paints for ships and fishing nets since the 1960s and have thus been
released into marine environments. Aquatic invertebrates, particularly marine gastropods, are extremely sensitive to organotin
compounds such as tributyltin (TBT) and triphenyltin (TPT) and undergo changes in sexual identity in response to exposure.
This worldwide phenomenon is one of the worst consequences of pollution by man-made chemicals and has led to the ban of such
compounds in antifouling paints in a number of countries, although organotin compounds still exist in the environment. So
far, very low-concentrations of TBT or TPT have been shown to induce imposex (superimposition of male genitalia on female)
in marine gastropods. Although the imposex induction mechanism has been controversial for many years, it was recently reported
that TBT and TPT are potent and efficacious activators of retinoid X receptor (RXR), a member of the nuclear receptor superfamily.
In this review, I discuss the involvement of RXR in the development of gastropod imposex.

Summary It perhaps would be unproductive at this point to debate whether the Kinneret was indeed threatened by the changes wrought in its watershed area and its utilization as a reservoir, or whether it has been eutrophic for thousands of years and would have continued so with or without human management. What is more important, perhaps, is that as a result of highly motivated government efforts, a useful mechanism has been established to provide data collection, constant feedback, physical planning, monitoring, research, and administration for the Kinneret and its watershed. Most important, the tripartite management group overseeing the Kinneret's interests, armed with an abundance of scientific data and administrative clout, has been able to transform facts into practical solutions. Their efforts are a welcome assurance that this important national and international resource will be protected, perhaps even improved, instead of merely saved for future generations. 相似文献

The objective of this study was to investigate the reproductive success (fertility and fecundity) of medaka (Oryzias latipes) exposed to 4-nonylphenol (4-NP) in water and the viability of their F(1) offspring. In addition, we measured the bioconcentration of 4-NP in eggs. After a 21-d exposure to 100microg/l 4-NP, medaka showed reduced egg production and fertility. Hepatic vitellogenin levels were increased significantly in males treated with 10, 50 and 100microg/l of 4-NP. In the F(1) generations, the hatchability and time to hatching of embryos in the 100microg/l treatment group were adversely affected, and 2-7microg 4-NP/g egg was found in spawned eggs (the bioconcentration factor: 30-100). These results indicate that (1) 4-NP adversely affected the reproduction (fecundity and fertility) of adult medaka, (2) 4-NP accumulated in eggs through maternal transfer and (3) these levels of 4-NP were associated with adverse effects in the F(1) offspring. 相似文献

Dynamics in the global protected-area estate since 2004 总被引:1,自引:0,他引:1

Nations of the world have committed to a number of goals and targets to address global environmental challenges. Protected areas have for centuries been a key strategy in conservation and play a major role in addressing current challenges. The most important tool used to track progress on protected-area commitments is the World Database on Protected Areas (WDPA). Periodic assessments of the world's protected-area estate show steady growth over the last 2 decades. However, the current method, which uses the latest version of the WDPA, does not show the true dynamic nature of protected areas over time and does not provide information on sites removed from the WDPA. In reality, this method can only show growth or remain stable. We used GIS tools in an approach to assess protected-area change over time based on 12 temporally distinct versions of the WDPA that quantify area added and removed from the WDPA annually from 2004 to 2016. Both the narrative of continual growth of protected area and the counter-narrative of protected area removal were overly simplistic. The former because growth was almost entirely in the marine realm and the latter because some areas removed were reprotected in later years. On average 2.5 million km2 was added to the WDPA annually and 1.1 million km2 was removed. Reasons for the inclusion and removal of protected areas in the WDPA database were in part due to data-quality issues but also to on-the-ground changes. To meet the 17% protected-area component of Aichi Biodiversity Target 11 by 2020, which stood at 14.7% in 2016, either the rate of protected-area removal must decrease or the rate of protected-area designation and addition to the WDPA must increase. 相似文献
