ABSTRACT: Integrated watershed management encompasses complex physical and social issues that have impacts on environmental resources. A key aspect of this holistic effort is public education. Most researchers and practitioners agree that an informed public is a crucial part of the environmental management process. Yet, educational programs that provide stakeholders with information about physical processes in watersheds are often unavailable. This paper assesses the effect of an education program for residents of the New York City watershed. Surveys evaluated certain knowledge levels and attitudes of participants and compared three groups: individuals who utilized the educational materials completely (full users), those who received the materials but did not use them completely (partial users), and watershed residents who did not receive the educational program (nonrecipients). Full users displayed a higher level of knowledge concerning specific watershed processes than did partial users and nonrecipients. In terms of applying that knowledge across linked concepts, however, we observed no significant differences between the three readership levels. Furthermore, partial users engaged in less evaluation of issues that related to the broader watershed context. The findings from this project have implications for educational and regulatory institutions and program development relating to watershed protection. 相似文献
This article presents a case study of an existing study abroad program to New Zealand interested in infusing sustainability
themes into the curriculum. The review of the program is set in the context of United Nations Education for Sustainable Development
goals and the role of sustainability in institutions of higher education. The author was an invited external observer and
suggests that study abroad programs in support of sustainability education provide transformative learning experiences that
invest in the well being of both people and places.

A 4year study surveyed 131 lakes across New York State beginning in 2003 to improve our understanding of mercury and gather information from previously untested waters. Our study focused on largemouth and smallmouth bass, walleye and yellow perch, common piscivorous fish shown to accumulate high mercury concentrations and species important to local fisheries. Fish from Adirondack and Catskill Forest Preserve lakes generally had higher mercury concentrations than those from lakes in other areas of the state. Variability between nearby individual lakes was observed, and could be due to differences in water chemistry, lake productivity or the abundance of wetlands in the watershed. We found the following factors impact mercury bioaccumulation: fish length, lake pH, specific conductivity, chlorophyll a, mercury concentration in the water, presence of an outlet dam and amount of contiguous wetlands. 相似文献
London and New York have often been hailed for their sustainable planning practices. However, when one focuses on the entire city region, there is ever-increasing car-dependent development. This paper focuses on the exurban region of the two cities investigating transport-created CO2 emissions. The research is based on the analysis of data of the National Travel Surveys of Great Britain and the USA through a quantification of personal travel and a top-down estimation of CO2 emissions. It is the exurban region that accounts for the vast majority of CO2 emissions: 77% for London and 87% for New York. In the wider region for both cities there is a policy vacuum and dearth of regional planning mechanisms to deliver policies to reduce CO2 emissions. The paper argues that transport needs to be planned at the city-regional scale. 相似文献
While the age of physical environments is the central tenet of historic preservation, there is a lack of empirical evidence about how everyday people actually value, perceive, and experience age as an intrinsic part of an urban environment. In order to ameliorate this knowledge deficit, this study employs phenomenology to understand the lived experience of being in a “new” versus an “old” or “historic” urban residential environment. The new environment is the I'On new urbanist development in Mt. Pleasant, South Carolina, and the old environment is the location of the United States' first historic district in Charleston, South Carolina. These locations are approximately within five miles of each other. In both places, the physical characteristics of the built environment are remarkably similar in density, form, layout, and design, but the age is dramatically different. Through photo elicitation techniques and interviews, the results of this study reveal that residents of historic Charleston and I'On value their built environments in remarkably similar ways. Surprisingly, elements that evoke a strong sense of attachment tend to be landscape features, such as gates, fountains, trees, and gardens rather than buildings. The informants valued the “mystery” that they felt was part of the landscape and which consisted of layered elements such as fences, gates, and paths, such that these features (including buildings) had to be “discovered.” Lastly, the informants strongly valued landscapes that showed “people care” through regular maintenance. The essential difference in people's experience and valuation of the new environment (I'On) and the old environment (historic Charleston) is in the older environment's ability to instill creative fantasies in the minds of the informants based on a hypothetical past of their own creation. The informants in I'On did not share these kinds of meanings. 相似文献
This paper describes the frustrating reality of sustainability implementation in the USA and New Zealand (NZ), an early adopter of sustainability mandates. Local government has a key role in implementation, but has been slow to uptake sustainable practices. We surveyed senior planners in small to medium-sized local government agencies in both countries to identify which features of local government support (or hinder) sustainability in practice.
Environmentally sustainable practices are not well entrenched in either country. In the USA, the framing of sustainability and public support are significant predictors of implementation. However, sustainability is rarely a priority. In NZ, local government capacity is the main driver of implementation. We recommend that planners promote sustainability values, reconcile economic development goals with sustainability (e.g., green economy model), and translate public support for sustainability into institutional priorities. NZ localities also need increased capacity and US localities need continued Federal and State support. 相似文献
The present study investigated the indoor concentrations of selected volatile organic compounds (VOCs) and formaldehyde and their indoor emission characteristics in newly-built apartments at the pre-occupancy stage. In total, 107 apartments were surveyed for indoor and outdoor VOC concentrations in two metropolitan cities and one rural area in Korea. A mass balanced model was used to estimate surface area-specific emission rates of individual VOCs and formaldehyde. Seven (benzene, ethyl benzene, toluene, m,p-xylene, o-xylene, n-hexane, and n-heptane) of 40 target compounds were detectable in all indoor air samples, whereas the first five were detected in all outdoor air samples. Formaldehyde was also predominant in the indoor air samples, with a high detection frequency of 96%. The indoor concentrations were significantly higher than the outdoor concentrations for aromatics, alcohols, terpenes, and ketones. However, six halogenated VOCs exhibited similar concentrations for indoor and outdoor air samples, suggesting that they are not major components emitted from building materials. It was also suggested that a certain portion of the apartments surveyed were constructed by not following the Korean Ministry of Environment guidelines for formaldehyde emissions. Toluene exhibited the highest emission rate with a median value of 138 μg m−2 h−1. The target compounds with median emission rates greater than 20 μg m−2 h−1 were toluene, 1-propanol, formaldehyde, and 2-butanone. The wood panels/vinyl floor coverings were the largest indoor pollutant source, followed by floorings, wall coverings, adhesives, and paints. The wood panels/vinyl floor coverings contributed nearly three times more to indoor VOC concentrations than paints. 相似文献
