A recent article in Environmental Management by All argued that flood flows in North America’s Colorado River do not reach the Gulf of California because they are captured
and evaporated in Laguna Salada, a below sea-level lakebed near the mouth of the river. We refute this hypothesis by showing
that (1) due to its limited area, the Laguna Salada could have evaporated less than 10% of the flood flows that have occurred
since 1989; (2) low flow volumes preferentially flow to the Gulf rather than Laguna Salada; (3) All’s method for detecting
water surface area in the Laguna Salada appears to be flawed because Landsat Thematic Mapper images of the lakebed show it
to be dry when All’s analyses said it was flooded; (4) direct measurements of salinity at the mouth of the river and in the
Upper Gulf of California during flood flows in 1993 and 1998 confirm that flood waters reach the sea; and (5) stable oxygen
isotope signatures in clam shells and fish otoliths recorded the dilution of seawater with fresh water during the 1993 and
1998 flows. Furthermore, All’s conclusion that freshwater flows do not benefit the ecology of the marine zone is incorrect
because the peer-reviewed literature shows that postlarval larval shrimp populations increase during floods, and the subsequent
year’s shrimp harvest increases. Furthermore, freshwater flows increase the nursery area for Gulf corvina (Cynoscion othonopterus), an important commercial fish that requires estuarine habitats with salinities in the range of 26–38‰ during its natal stages.
Although flood flows are now much diminished compared to the pre-dam era, they are still important to the remnant wetland
and riparian habitats of the Colorado River delta and to organisms in the intertidal and marine zone. Only a small fraction
of the flood flows are evaporated in Laguna Salada. 相似文献

An emerging conflict with Trans-Himalayan pastoral communities in Ladakh’s Changthang Plateau threatens the conservation prospects
of the kiang (Equus kiang) in India. It is locally believed that Changthang’s rangelands are overstocked with kiang, resulting in forage competition
with livestock. Here, we provide a review and preliminary data on the causes of this conflict. Erosion of people’s tolerance
of the kiang can be attributed to factors such as the loss of traditional pastures during an Indo-Chinese war fought in 1962,
immigration of refugees from Tibet, doubling of the livestock population in about 20 years, and increasing commercialization
of cashmere (pashmina) production. The perception of kiang overstocking appears misplaced, because our range-wide density estimate of 0.24 kiang
km−2 (± 0.44, 95% CL) is comparable to kiang densities reported from Tibet. A catastrophic decline during the war and subsequent
recovery of the kiang population apparently led to the overstocking perception in Ladakh. In the Hanle Valley, an important
area for the kiang, its density was higher (0.56 km−2) although even here, we estimated the total forage consumed by kiang to be only 3–4% compared to 96–97% consumed by the large
livestock population (78 km−2). Our analysis nevertheless suggests that at a localized scale, some herders do face serious forage competition from kiang
in key areas such as moist sedge meadows, and thus management strategies also need to be devised at this scale. In-depth socioeconomic
surveys are needed to understand the full extent of the conflicts, and herder-centered participatory resolution needs to be
facilitated to ensure that a sustainable solution for livelihoods and kiang conservation is achieved. 相似文献

Key aspects of environmental management exist within a legislative framework. The Rivers and Foreshores Improvement Act 1948 (NSW) and several Regional Environmental Plans created under the Environmental Planning and Assessment Act 1979 (NSW) make reference to ‘the top of the bank’ for defining areas of protected land adjacent to rivers, within which development
consent may be required. It is an arbitrary term and its use within the Rivers and Foreshores Improvement Act 1948 (NSW) leads to confusion. This paper examines the range of definitions of ‘the top of the bank’ in respect of natural watercourses
and aims to provide a more lucid and effective definition that will clarify existing ambiguities in legal interpretation.
The paper examines the historical origins of the phrase ‘top of the bank’, finding that stereotyped Eurocentric views of what
a river ‘should look like’ have impaired the legal definition for Australian rivers, thereby influencing common law and the
development of statutory definitions. Judicial applications of the phrase ‘top of the bank’ are examined from a geomorphological
perspective, demonstrating the misconceptions of the term in a legal context. The paper identifies the existence of widespread
support for the need to protect land adjacent to rivers in the interests of environmental, economic and social sustainability.
It concludes by calling for legislative reform that is both tailored to the individual site and consistent with overarching
goals at the catchment scale. 相似文献

Citizens’ Views on Farm Animal Welfare and Related Information Provision: Exploratory Insights from Flanders,Belgium 总被引:1,自引:0,他引:1
Filiep Vanhonacker Els Van Poucke Frank Tuyttens Wim Verbeke 《Journal of Agricultural and Environmental Ethics》2010,23(6):551-569
The results of two independent empirical studies with Flemish citizens were combined to address the problem of a short fall
of information provision about higher welfare products. The research objectives were (1) to improve our understanding of how
citizens conceptualize farm animal welfare, (2) to analyze the variety in the claimed personal relevance of animal welfare
in the food purchasing decision process, and (3) to find out people’s needs in relation to product information about animal
welfare and the extent to which the current information caters to these needs. The first study consisted of a survey conducted
in three consecutive years (2000–2002, n = 521) and was complemented with more recent qualitative data from four focus group discussions (2006, n = 29). Citizens’ conceptualization of farm animal welfare matched reasonably well with those in the scientific literature,
although it is clearly influenced by a lower level of practical experience and a higher weight of empathy. In general, respondents
indicated that animal welfare was an important product attribute, although it was less important than primary product attributes
such as quality, health, and safety. Moral issues, rather than a perception of higher quality, were the main influence on
preferences for higher welfare products. At present, higher standards of animal welfare are mostly guaranteed within more
general quality assurance schemes. Yet people’s decisions to not choose higher welfare products seems to be related to the
perceptual disconnection between eating animal food products and the living producing animals. Respondents generally thought
better information provision was required and the present level of provision was strongly criticized. In combination, the
findings of both studies help inform the discussion about how citizens can be informed about animal welfare and the preferred
content, source, and medium of such information. The paper also provides insights into citizens’ semantic interpretation of the concept of animal welfare (what wordings they use) and the range of relevance that animal welfare has for different groups that, in turn is useful in identifying which segments can be targeted. This can contribute to a more effective valorization of animal welfare as a product attribute. 相似文献

According to the United States Environmental Protection Agency (US EPA), a significant percentage of residential onsite sewage
systems (OSSs) are failing at any given time. The US EPA has therefore issued a set of recommended guidelines for OSS regulatory
programs aimed at reducing overall failure rates. We conducted a survey of OSS regulatory program administrators with jurisdictions
bordering a Great Lake. Our goal was to determine their programs’ capacities to meet the US EPA’s recommendations. We found
that although some local programs meet the US EPA’s recommendations, most do not. In this article, we present our findings
and conclusions for one of the US EPA’s models, the baseline “Homeowner Awareness” model. Most areas do not have recommended
requirements that systems be inspected when properties transfer between owners. A majority do not track changes in ownership
within the computerized databases they use to record information about systems. Although most provide at least “one-time”
information to homeowners regarding proper OSS maintenance, most do not contact them periodically with reminders of needed
maintenance. We include recommendations for resolving some of the issues that our research identified. 相似文献

The European Union’s policies regarding genetically modified food (GMF hereafter) are based on the precautionary principle
and the requirement of respecting consumers’ autonomy. We ask whether the requirement of respecting consumers’ autonomy regarding
GMF implies that both GMF and non-GMF products should be available in the market. According to one line of thought, consumers’
choices may be autonomous even when the both types of products are not available. A food market with only GMF or only non-GMF
products does not strictly speaking compel people to buy the type of products available, and a possibility to refuse to buy
is enough for consumers’ choice to be autonomous. According to another line of thought, the unavailability of GMF or non-GMF
products restricts the autonomy of those consumers who are unwilling to use the only type of products (GMF or non-GMF) available
in the market. From the point of view of autonomy, a food market with only GMF or only non-GMF products does not offer enough
alternatives for consumers. Moreover, the whole point of the European Union’s requirement of respecting consumers’ autonomy
is to enable an autonomous choice between GMF and non-GMF—not just to give a possibility to refrain from buying. However,
this does not imply that producers, processors, wholesalers, retailers, or public authorities have a moral duty to see that
there are both GMF and non-GMF products available in the market. The requirement to respect autonomy is prima facie in nature, and in the context of GMF, other prima facie requirements are often stronger and override it. Not only the consumers’ autonomy of choice but also environmental values,
other people’s well-being, and the autonomous choice of farmers, retailers, and other relevant parties should be respected.
Thus, according to the both lines of thought, the requirement to respect consumers’ autonomy of choice does not imply that
there should be both GMF and non-GMF products available in the market. 相似文献

Summary The problems of man’s increasing abuse and misuse of his environment are multiplying in direct proportion to the increase
in the human population. This is particularly true of much of the Third World, where often a low level of literacy is accompanied
by a steadily growing birthrate. Small island habitats, because of their long geological separation from the large land masses
frequently have flora and fauna that are unique but the pressures on their environment are considerably greater. In the struggle
to compete in an increasingly mechanised and industrial world they are forced to devastate the natural habitat of many of
their indigenous species in order to obtain agricultural land, building materials and fuel. While wooing the tourist market
on the one hand with the beauty of their beaches, they are at the same time removing the sand wholesale for construction purposes.
If the people themselves are to survive, industrial growth is quite obviously essential. Because the practices that at present
place the environment under threat are, in many cases, vital to the individual’s ability to support himself, reasonable alternatives
must be offered before they can be effectively controlled.
Ms Maria Grech came to Saint Lucia originally in 1961 and spent almost eighteen years in the restaurant business. When she
sold out in 1979 she decided to devote more time to writing and specifically to writing about the island which had become
her home. For two years now she has written and illustrated a monthly conservation news-sheet that is distributed throughout
the schools here by the local Forestry Division. In November 1981 the paper—Bush Talk—was awarded a prize for creative journalism and funding is now being sought to have it published in book form.
She is an executive member of the Saint Lucia Naturalists’ Society and is currently compiling their first year book. She has

Norton argues on pragmatic “Deweyan” grounds that we should cease to ask scientists for value neutral definitions of “sustainability,”
developed independently of moral and social values, to guide our environmental policy making debates. “Sustainability,” like
human “health,” is a normative concept from the start—one that cannot be meaningfully developed by scientists or economists
without input by all the stake holders affected. While I endorse Norton’s approach, I question his apparent presumption that
concern for sustainability for the future is at odds with and ought to trump concern for enhancement in the present of public opportunities to access the goods nature represents. I argue that the two are not separable in practice.
I argue for Passmore’s position that unless we take care to enhance equitable access to the good and services nature represents
in the present, we cannot succeed in promoting sustainability for future generations. 相似文献

With record-breaking tourist visits in Kenya in 2005–2006, communities near the country’s renowned protected areas must undertake
or revisit planning efforts to conserve and enhance the region’s natural, social, and economic resources. This article examines
the differences between two stakeholder groups in the Samburu region of central Kenya: (1) protected area leadership and staff;
and (2) members of the communities adjacent to the protected areas. Based on the results and analysis of 30 in-depth interviews,
the authors identify differences between protected area staff and their community members regarding perceptions about communication
between the two groups, and the economic benefits of tourism. The different stakeholders agreed, however, about challenges
related to equitable distribution of tourism-based employment and revenue. The results indicate a need to reach consensus
about what constitutes sufficient communication between national reserves and their community, and to what extent tourism-related
revenue and employment should be distributed within the region. A discussion of the potential role of indicators and standards
to make such decisions is presented. 相似文献

“A skyscraper is as natural as a bird’s nest” –Alan Watts
For millennia, people have altered freshwater ecosystems directly through water development and indirectly by global change
and surrounding land-use activities. In these altered ecosystems, human impacts can be subtle and are sometimes overlooked
by the people who manage them. This article provides two case studies near Boulder, Colorado that demonstrate how perceptions
regarding these ecosystems affect their management. These examples are typical of lakes and streams along the Front Range
of Colorado that are simultaneously natural and social in origin. Although natural, many of the region’s freshwater ecosystems
are affected by ongoing ecologic, hydrologic, chemical, and geomorphic modifications produced by human activity. People and
nature are both active participants in the production of these freshwater ecosystems. The concept of “hybridity,” borrowed
from geographers and social scientists, is useful for describing landscapes of natural and social origin. Hybrid freshwater
ecosystems are features of the humanized landscape and are derived from deliberate cultural activities, nonhuman physical
and biological processes, and incidental anthropogenic disturbance. Our perceptions of “natural” freshwater ecosystems and
what definitions we use to describe them influences our view of hybrid systems and, in turn, affects management decisions
regarding them. This work stresses the importance of understanding the underlying societal forces and cultural values responsible
for the creation of hybrid freshwater ecosystems as a central step in their conservation and management. 相似文献

U.S. Forest Service managers are required to incorporate social and biophysical science information in planning and environmental
analysis. The use of science is mandated by the National Environmental Policy Act, the National Forest Management Act, and
U.S. Forest Service planning rules. Despite the agency’s emphasis on ‘science-based’ decision-making, little is known about
how science is actually used in recreation planning and management. This study investigated the perceptions of Forest Service
interdisciplinary (ID) team leaders for 106 NEPA projects dealing with recreation and travel management between 2005 and 2008.
Our survey data show how managers rate the importance of social and biophysical science compared to other potential ‘success
factors’ in NEPA assessments. We also explore how team leaders value and use multi-disciplinary tools for recreation-related
assessments. Results suggest that managers employ a variety of recreation planning tools in NEPA projects, but there appears
to be no common understanding or approach for how or when these tools are incorporated. The Recreation Opportunity Spectrum
(ROS) was the most frequently used planning tool, but the Visitor Experience and Resource Protection (VERP) framework was
the most consistently valued tool by those who used it. We recommend further evaluation of the strengths and weaknesses of
each planning tool and future development of procedures to select appropriate planning tools for use in recreation-related
NEPA assessments. 相似文献

This study reports how Traditional Ecological Knowledge (TEK) and informal cultural institutions have conserved key varieties
of the wildgrowing rice, ‘tinni’ (red rice, or brownbeard rice, Oriza rufipogon Griff.), within the Bhar community of eastern Uttar Pradesh, India. The study was conducted, using conventional and participatory
methods, in 10 purposively selected Bhar villages. Two distinct varieties of tinni (‘tinni patali’ and ‘tinni moti’) with differing habitats and phenotypic characters were identified. Seven microecosystems (Kari, Badaila, Chammo, Karmol,
Bhainsiki, Bhainsala and Khodailia) were found to support these varieties in differing proportions. Tinni rice can withstand more extreme weather conditions (the highest as well as lowest temperatures and rainfall regimes) than
the ‘genetically improved’ varieties of rice (Oriza sativa L.) grown in the region. Both tinni varieties are important bioresources for the Bhar’s subsistence livelihoods, and they use distinctive conservation approaches
in their maintenance. Bhar women are the main custodians of tinni rice agrobiodiversity, conserving tinni through an institution called Sajha. Democratic decision-making at meetings organized by village elders determines the market
price of the tinni varieties. Overall, the indigenous institutions and women’s participation seem to have provided safeguards from excessive
exploitation of tinni rice varieties. The maintenance of tinni through cultural knowledge and institutions serves as an example of the importance of locally maintained crop varieties in
contributing to people’s resilience and food security in times of rapid social and environmental change. 相似文献

The Lyon-Turin High-Speed Rail: The Public Debate and Perception of Environmental Risk in Susa Valley,Italy 总被引:1,自引:1,他引:0
When the construction of the Lyon-Turin segment of the new European high-speed rail network was first publicly announced at
the beginning of the 1990s, it immediately found fierce opposition from the inhabitants of Susa Valley, Italy, one of the
areas to be cut across by such infrastructure. At issue were the project’s potential environmental impact and its consequences
on public health. This study intends to clarify environmental risk perception and public debate between the national government,
local advocacy groups, and the inhabitants of Susa Valley. Two major phases of public reaction were identified: (1) an initial
rebellious period of no real dialog among the project’s major stakeholders (exemplified by the popular “No TAV” [No High Speed
Train] movement), followed by (2) a yielding period of intense multilateral negotiations centered on the activities of the
“Lyon-Turin Environmental Observatory.” The results of a qualitative cross analysis of the residents’ perception of the proposed
high-speed rail revealed that public acceptance of risk in Susa Valley was influenced by the characteristics of hazards perceived
by the residents and by the communicative approach used by the project’s various stakeholders. It also emerged that early
dialog among all the parties involved was critical in forming a personal viewpoint on risk, which, once consolidated, defied
new information and perspectives. Likely, a greater and earlier care taken by the other stakeholders to inform and consult
the local population about the railway would have greatly eased the public debate. 相似文献

Although various studies have shown that farmers believe there is the need for a producer-led initiative to address the environmental
problems from agriculture, farmers in several Canadian provinces have been reluctant to widely participate in Environmental
Farm Plan (EFP) programs. Few studies have examined the key issues associated with adopting EFP programs based on farmers’,
as opposed to policy makers’, perspectives on why producers are reluctant to participate in the program. A study adapting
Van Raaij’s (1981) conceptual model of the decision-making environment of the firm, and prospect theory on value functions
associated with the gains and losses from risky choices can be used to characterize how farmers perceive potential risks in
environmental farm planning. This framework can be used to assert that farmers are concerned about risks of public disclosure
of potentially incriminating environmental information from farms because the EFP program requirements for identification
and extensive documentation of farm information is perceived by farmers as facilitating the accessibility of environmental
information to the public, and public investigative efforts. Although the EFP program does not explicitly generate information
about the environmental conditions of a farm nor the disclosure of such information to the public, it creates the possibility
of generating and divulging potentially incriminating information that the farmer may want to treat as confidential. Yet,
alone, these risks of public disclosure concerns should not prevent farmers from participating in the EFP. Awareness of and
participation in environmental farm planning can be increased if farmers and policy makers understand what the risks are,
and how they arise. Aspects of the EFP process that have the potential to generate risk of public disclosure concerns relate
to farm reviews, documentation and record keeping, and corrective action plans. There are legal and policy instruments that
can offer various forms of protection and help minimize such risks, and these need to be assessed. 相似文献

Managing Nonpoint Source Pollution in Western Washington: Landowner Learning Methods and Motivations 总被引:1,自引:1,他引:0
Clare M. Ryan 《Environmental management》2009,43(6):1122-1130
States, territories, and tribes identify nonpoint source pollution as responsible for more than half of the Nation’s existing
and threatened water quality impairments, making it the principal remaining cause of water quality problems across the United
States. Combinations of education, technical and financial assistance, and regulatory measures are used to inform landowners
about nonpoint source pollution issues, and to stimulate the use of best management practices. A mail survey of non-commercial
riparian landowners investigated how they learn about best management practices, the efficacy of different educational techniques,
and what motivates them to implement land management activities. Landowners experience a variety of educational techniques,
and rank those that include direct personal contact as more effective than brochures, advertisements, radio, internet, or
television. The most important motivations for implementing best management practices were linked with elements of a personal
stewardship ethic, accountability, personal commitment, and feasibility. Nonpoint source education and social marketing campaigns
should include direct interpersonal contacts, and appeal to landowner motivations of caring, responsibility, and personal
commitment. 相似文献

The term natural is effective in the marketing of a wide variety of foods. This ambiguous term carries important meaning in Western culture.
To challenge an uncritical understanding of natural with respect to food and to explore the ambiguity of the term, the development of Western ideas of nature is first discussed. Personification and hypostasization of nature are given special emphasis. Leo Marx’s idea of the pastoral
design in literature is then used to explore the meaning of natural as applied to food, emphasizing Marx’s distinction between
a sentimental and a complex pastoral. The latter is applied to natural as a means of collapsing a dichotomy of man and nature to the idea of second nature. From this perspective an understanding of the industrialization of the food system and the importance of local and organic
food are considered. The extent to which processed foods might properly be considered natural is raised and discussed for
several common foods. Although marketing of natural foods might make us think that we consume nature, I suggest that what
is consumed is more appropriately second nature. I suggest that in order to maintain a critical perspective about one’s relationship
to the natural world, everyone should make an attempt to experience the complex pastoral with respect to at least something
that is consumed as food. When nature is understood as second nature in the context of a complex pastoral, the question of
whether a food or ingredient is to be considered natural is replaced by deliberative thought based on our best knowledge and
judgment, and the result will be less constrained by ideology. 相似文献

There is a “revolving door” between federal agencies and the industries regulated by them. Often, at the end of their industry
tenure, key industry personnel seek employment in government regulatory entities and vice versa. The flow of workers between
the two sectors could bring about good. Industry veterans might have specialized knowledge that could be useful to regulatory
bodies and former government employees could help businesses become and remain compliant with regulations. But the “revolving
door” also poses at least three ethical and policy challenges that have to do with public trust and fair representation. First,
the presence of former key industry personnel on review boards could adversely impact the public’s confidence in regulatory
decisions about new technology products, including agrifood biotechnologies. Second, the ‘‘revolving door’’ may result in
policy decisions about technologies that are biased in favor of industry interests. And third, the ‘‘revolving door’’ virtually
guarantees industry a voice in the policy-making process, even though other stakeholders have no assurance that their concerns
will be addressed by regulatory agencies. We believe these three problems indicate a failure of regulatory review for new
technologies. The review process lacks credibility because, at the very least, it is procedurally biased in favor of industry
interests. We argue that prohibiting the flow of personnel between regulatory agencies and industry would not be a satisfactory
solution to the three problems of public trust and just representation. To address them, regulatory entities must reject the
traditional notion of objectivity. Instead they should adopt the conception of objectivity developed by Sandra Harding and
re-configure their regulatory review on the basis of it. That will ensure that a heterogeneous group of stakeholders is at
the decision-making table. The fair representation of interests of different constituencies in the review process could do
much to inspire warranted public confidence in regulatory protocols and decisions. 相似文献

A commitment to conservation of a place is based on the sense of place expressed by its “conceptual community”, including
those who are not its residents in the geographical sense, but who nonetheless identify with it for various reasons. With
the global nature of environmental issues being clearly recognized, such communities form a “terrain of consciousness” (Berg and Dasmann 1978), extending responsibility for conservation across cultures, time and space. Although the social
mobility and diversity brought about by today’s technology often work against the development of a sense of place, they also
allow the formation of such conceptual communities, who can highlight local distinctiveness while at the same time positioning
local issues in a global context, so generating a sense of global responsibility. In the case of Tasmania, Australia, recent
international interest in its ecologically and culturally significant places, such as Recherche Bay and the Styx Valley, has
intensified the focus on forest issues, building on Tasmania’s already well-recognized history of environmentalism. It is
important that these issues be recognized in Japan in particular, where a rising awareness about climate change and mass consumerism
has alerted the public to the problem of deforestation; however the fact that Tasmania is one of the major sources of woodchips
for paper production is not widely known. Awareness by the consumer, it is argued, is a foundation for forming a sense of
global responsibility and it is necessary to form a conceptual community of those committed to the same issue. Cross-cultural
collaboration is therefore necessary, and creativity can be an effective facilitating agent for this. This paper illustrates
this point, through the example of the Kodama Forest, a forest of tree spirits, in North East Tasmania, that arose from such a collaboration between a group of Japanese students and a local community
group. The collaboration also facilitated meaningful learning opportunities for the students, who chose to study in Tasmania
because of its natural environment. The forest now provides a cultural heritage that also defines the evolution of this conceptual
community through on-going collaboration. The importance of human connection at all levels, local, regional and global, in
promoting environmental sustainability is addressed through the example of this forest. 相似文献

The changing face of public concern about pollution in the United States: A case study of New Jersey
National surveys and a survey conducted by the authors in March and April 2004 revealed that the public’s concerns about air,
water and land pollution have declined during the last four years in the United States and more specifically in the State
of New Jersey. In New Jersey pollution remains a major concern of most residents, even during a period of a war, anxiety about
terrorism and the economy. Those most anxious about pollution do not believe that government is doing enough to protect the
environment, want to maintain current environmental laws, and are worried about the future. Disproportionately they are African
and White Americans, middle income, and college graduates, in other words, part of the American mainstream.
Direct attempts to weaken environmental protection are likely to be resisted by this core of the population, which does not
trust current federal, state and local governments to protect the environment. We expect concerns for the environment to continue
and yet change as production processes in the United States continue a trend toward pollution prevention, and we wait for
the public’s mental models to catch up with this evolving reality. 相似文献
