Biological diversity conservation: A public policy perspective

While extinctions of individual species are part of a normal cycle, the current rate of extinctions should be a concern to us all. The maintenance of biological diversity is important for utilitarian reasons, quality of life considerations, and because biodiversity is important to sustainable regional economies. Single-species approaches are too limited to protect biodiversity at the landscape, habitat, and watershed levels. New approaches are necessary to deal with the complexity of biological diversity. The administration is using provisions in the Endangered Species Act to bring about broader multispecies habitat protection. The ecosystem approach provides a framework for ensuring that ecological considerations are taken into account, along with economic and social factors, and that all interested parties are able to participate in the decision-making process.     

Indigenous Grass Ecology and Socio-Economic Values in Swaziland

The fast-degrading land resources of Swaziland requires a multi-faceted approach to their management. One resource of utmost importance to all Swazis is grass. Grass research over the years had focused on pasture grass, while other uses have been neglected. The omission is a serious one and could be attributed to the neglect of indigenous grass knowledge and people's socio-economic values of grasses. Grass as a major resource is used for cattle feed, ecological control measures, medicinal plants and crafts. Within the study area, 46 grass species were identified and described by the local people. The neglect of the people's knowledge and utilitarian values of grass is a waste of resources. Thus, for grass research to be relevant to the people and national development objectives, research scientists should rethink their approach; they need to recognize and incorporate the indigenous knowledge about other uses of grasses.     

The effects of perceived conflict,resource scarcity,and information bias on emotions and environmental decisions

The failure to anticipate the public's response to environmental problems can lead to expensive delays, bad public relations, and litigation, as well as environmental decisions that do not represent public values and preferences. This study examines the influence of conflict between management goals, perceived resource scarcity, and information bias on evaluations of the importance of management goals; the perception of conflicts among the goals; and the emotions evoked in an urban forest management problem. Environmental problem scenarios were systematically manipulated as to the level of conflict between development and natural preservation goals, the scarcity of urban nature, and the bias of the presented information. Evaluations of the importance of urban nature and economic development were susceptible to manipulations of scarcity. The importance of urban nature was also higher when information was biased toward pro-preservation issues. Negative emotions were associated with high conflict and scarcity and with the propreservation information bias. Both evaluations of goal importance and conflict among goals appeared to be based on an underlying economics-versus-amenity dimension. These results are similar to previous studies of environmental decision making with regard to nonurban environmental problems. This research offers a beginning in understanding and anticipating the way members of the public may respond to information about environmental problems.     

Recombinant bovine somatotropin (rbST): Is there a limit for biotechnology in applied animal agriculture?

The intent of this article is to outline, integrate, and interpret relevant scientific, economic, and social issues of rbST technology that have contributed to the acceptance dilemma for this product. The public is divided into social groups, each with its own set of criteria on which they base rbSTs acceptability. Criteria for the scientific community may best be described as physiological. However, for consumers, criteria may be more practical, or procedural, including human health, animal welfare, environmental concerns, and overproduction. Because the business of dairy production depends on demand from the consuming public, the criteria for acceptance of rbST by producers largely reflects those of the consumers. Of necessity, producers are also critical of rbST from a business and animal improvement standpoint. Although this article demonstrates that rbST has met most physiological criteria for acceptance, the consuming public has treated the acceptance issue with forceful skepticism. The question this article addresses is, why? The authors comment that with rbST and other biotechnologies applied to agricultural animal production, it will be the responsibility of government health agencies, scientists, and manufacturers of the products to provide early, adequate, and honest public education. Attention to the concerns of the public may be the only means to prevent hysteria over this and future agricultural products of biotechnology and will, therefore, allow the public to form logical and thoughtful criteria assessments with respect to acceptance or rejection of each product.     

European winegrowers’ perceptions of climate change impact and options for adaptation

A questionnaire on the perception of climate change and the impact of climate change was distributed among winegrowers in France, Germany, and Italy. These countries are located in three macro-climatic regions that experienced different patterns of climatic change in the twentieth century—Atlantic, transition to Continental and Mediterranean. The majority of winegrowers perceived changing climatic conditions in the last few decades. The characterization of these changes is consistent with results obtained by the analysis of long-term trends in climatic records. The winegrowers noted impacts on harvestable quantities (mainly in Italy), must quality, and risks of pests and diseases. The majority of respondents (66%) indicated an impact on wine quality, which was perceived as quality improvement in 55% of the cases. Perceived impacts on pests and diseases were reported in 56% of the responses. A strong majority of this group (80%) also reported increasing threats. Perceived climatic change and its noticeable impacts has led to growing interest in adaptation options, combined with a need for more information, among winegrowers. Thus, the transfer of technical knowledge from scientific research to practice is necessary for adaptation. Plans for adaptation by a change of wine varieties were reported with substantially different results among the regions. A majority of German growers said they would consider changing varieties to adapt to warming temperatures, while only a minority of the Italian and French growers said they would consider such changes. However, readiness to adopt adaptation measures is correlated with the degree of changes already planned, independent of climatic change.     

Living in grey areas: Industrial activity and psychological health

The main goal of this paper was to explore the relationship between living in industrial areas and individual’s level of psychological health. Using a quasi-experimental design main findings suggest that, regardless of the type of industry that is operating, there was a significant association between living in industrialized areas and decreased levels of well being, optimism and use of active coping strategies. However, results on anxiety and depression were especially high in areas associated with air pollution. Moreover, there was also a significant association between more subjective meanings of place and psychological health. According to a reality-orientation criterion, evidences showed that when individuals live in industrial areas perceptions of their places as industrial are associated with lower depression, anxiety and psychiatric symptoms.     

Non-market values of forest biodiversity and the impact of informing the general public: Insights from generalized multinomial logit estimations

Apart from the ethical argument around trade-off that individuals have to make between monetary and non-monetary value, application of stated preference method was exposed to another criticism related to the complexity of biodiversity issue and the capacity of the general public to provide accurate responses to willingness to pay elicitation survey. This paper tests how providing information about the ecological processes underlying forest management scenarios affects public preferences and their valuation of biodiversity in publicly owned forest land in France. The generalized multinomial logit models applied to choice experiment data suggests that all respondents adopt the same heuristics based on easily visible aspects of forest landscape, to reveal their use and nonuse values of biodiversity. However, when they receive additional ecological information, only those who are familiar with the biodiversity concept, have awareness of issues at stake, and have a regular use of forest tend to attach higher values to less known biodiversity component (fallen deadwood in this case). The paper concludes that “mass media campaign” has to be completed by environmental literacy programs, to improve people’s awareness and understanding of what biodiversity means from ecological functioning, then making economic valuation a useful tool from a conservation perspective.     

“The Good Life”: Engaging the public with community-based carbon reduction strategies

In recent years the UK has positioned itself to become a global leader in addressing climate change. Along with this positioning, there has been an increasing emphasis on the role of communities to facilitate, increase and sustain carbon reduction practices. Previous research into community-based carbon reduction projects has highlighted the difficulty of engaging the public in community initiatives and sustaining pro-environmental behaviours. The importance placed on addressing climate change necessitates an understanding of how individuals respond to, and engage with, (or even ignore) community-based carbon reduction strategies. The paper presents findings from focus groups in three urban communities and investigates individual engagements with community-based carbon reduction strategies. Focusing on the three dimensions of engagement: cognitive; affective and; behavioural, the paper discusses what people know, feel and do about addressing climate change at the community level. An “information-vacuum” is reported that leads to an “awareness-involvement gap” that inhibits sustained engagement with community projects. Drawing on these findings, the paper advances a new theoretical framework and a “what works” approach for community-based initiatives attempting to meaningfully engage the public with addressing climate change and sustainable living.     

Risk communication in the internet age: The rise of disorganized skepticism

Communicating risks has become a core ingredient in the regulatory functions of government, interest group advocacy, public health, and corporate relations. The channels of risk communication have grown in complexity along with the development and expansion of the Internet and the birth of personalized blogging. This paper discusses three stages in the development of risk communication as an area of study and research. It examines the way risk is framed in three channels of communication, newsprint, the Expanded Academic Index, and Google using the example of the controversial chemical perfluorooctanoic acid (PFOA). The paper concludes that the Internet, as illustrated by the Google search engine, has created more opportunities for citizen learning and expanded the breadth and channels of risk communication, while also providing new opportunities for stakeholders to influence the message. Democritization of information does not necessarily create greater concordance between the cultural and technical assessment of risk.     

Emotions,habits and rational choices in ecological behaviours: The case of recycling and use of public transportation

Two field studies examined the role of attitudes, subjective norms, perceived control, anticipated emotions, past behaviour and desire in the prediction of pro-environmental behavioural intention. The model of goal-directed behaviour (MGB) was applied to predict intentions to use public transportation instead of the private car for going to work (Study 1, N=180), and to recycle household waste (Study 2, N=154). Multiple regression and structural equation modeling were used to test the hypotheses in studies 1 and 2, respectively. As expected, results of the two studies indicate that negative anticipated emotions and past behaviour are significant predictors of desire to engage in pro-environmental action. Desire, in turn, positively predicts pro-environmental behavioural intentions. A direct link between past behaviour and intentions was also detected. Implications of the results for the promotion of pro-environmental behaviour are discussed.
