Sustainable consumption: the effects of knowledge,cultural values,environmental advertising,and demographics

As a result of human lifestyles and unsustainable consumption patterns, the environment continues to deteriorate and thus inhibit sustainable development. In order to curb this situation and promote a sustainable economy, one of the solution is to reduce conventional products consumption and shift to green products. Over the past 20 years, marketing managers keenly seek to understand the green market; however, inadequate information on how to promote consumers’ green behavioral intentions is slowing the growth of green markets and becomes a barrier for firms when developing segments and communicating strategies for effective promotion of green products in countries like Malaysia where the trend is fairly new. Therefore, this study attempts to examine the impact of environmental knowledge, cultural values, and environmental advertising and determine the moderating effect of income level, education level, and gender on consumers’ green purchase intentions. A survey was administered, and a total of 405 valid questionnaires were obtained. Structural equation modeling technique was used to evaluate the causal model by using SmartPLS 2.0 software. The finding results suggest that cultural values and environmental advertising are the main influences in building green purchase intentions, while environmental knowledge is not significantly related. The results also indicate that education level and gender have a significant positive moderation effect while income did not. This suggests that green purchase intentions’ motivational factors are greater among highly educated individuals, with females in particular. The discussions and implications of these findings are further elaborated.     

Traditional Ecological Knowledge and Practice for Edible Wild Plants: Biodiversity Use by the Rarámuri,in the Sirerra Tarahumara,Mexico

The Rarámuri who live in the Sierra Tarahumara of Chihuahua State, Mexico have developed local knowledge and harvesting strategies for edible wild plants that have the effect of conserving the biodiversity of their forest ecosystem. This paper presents the results of ethnobotanical research undertaken in the community of Basìhuare in the Sierra Tarahumara, to provide details on some practical aspects of the Raráamuri worldview regarding interconnections between people and their environment. This traditional philosophy forms the basis for the use of edible wild plants and the harvesting strategies practiced in Basìhuare, such as selective harvesting, environmental modification and domestication. These activities provide the opportunity for harvesters to monitor the landscape and the plant resources that occur on the land, as well as present a setting for the communication and exchange of traditional ecological knowledge. However, Rarámuri harvesting practices are under stress because of increased external pressures from commercial timber extraction and other development. We discuss the state of traditional ecological knowledge and its transmission in the context of development activities in the region. The key to sustainability in the Sierra Tarahumara may be the maintenance of traditional management practices for edible wild plants, and other nontimber forest products, that lead to the conservation of biodiversity by creating patchiness and renewing the plant cover on the land.     

Sharing and preparing: cross-institutional,food security-based knowledge in Canada

This study proposes a framework for the collection and management of knowledge related to food security in Canada. This paper has several goals. First, the paper summarizes the current state of food security knowledge in Canada. Second, the paper presents data from an experiment where food security issues were discussed by stakeholders at two fora, the first of which was held in western Canada and the second held in eastern Canada. Finally, based on the notes taken during and feedback received after the fora, this paper suggests a framework for organizing and managing the multiple perspectives and complex types of knowledge about food security and sustainable development from a Canadian context. Two fora were held in Canada where food security issues were presented and discussed by multiple stakeholders. Most provinces in Canada were represented in at least one of the two sessions. Sessions were designed to be informative and interactive; agenda were designed to take advantage of the needs and experiences of multiple stakeholders in both western and eastern regions of Canada. To develop the framework, the sessions were also designed to assess the types of issues and knowledge about food security in Canada. Evidence presented from this experiment supports arguments that food security work must be approached in a collaborative manner, no matter the approach or discipline. Data from fora held in western and eastern regions of Canada indicate a number of specific ways in which those along the food continuum have the desire to share knowledge and enter into partnerships to work toward secure and sustainable food systems. Data also indicate how academia and institutions of higher learning might play a key role in sharing food security-based knowledge. The data from this study suggest that academia could play a leadership role in collecting and sharing information about food security-based knowledge from all disciplinary approaches that could help collaborative in addressing the complexity of food security challenges. The framework developed in this paper could provide the guide for organizing knowledge about food security and sustainable development. The framework could be used as a map to guide understanding about the different ways in which food security can be approached and understood; this could help reduce tensions among partners in projects where a wide variety of experiences are attempting to work collaboratively. The two food security fora brought together stakeholders with specialized knowledge about food security in a Canadian context. The analysis of data arising from the fora permitted unique insights to arise about the nature of knowledge by region. The data in this study also allowed us to build a framework for food security knowledge from these regional knowledge bases. This paper suggests that academia actively take a leadership role and openly share knowledge about food security. Open sharing of knowledge will help collaborates in dealing with complex food security issues understand in-depth other approaches; this sharing may help to make explicit the tensions that arise during collaborative work.     

Utility optimization strategy of safety management capability of coal mine - A case study of JCIA

This article describes optimization strategy of SMCCM from perspective of utility of coal miner with the method of empirical research. Four elements of SMCCM are put forward which consist of “employee safety knowledge”, “equipment safety knowledge”, “environment safety knowledge” and “rule safety knowledge”. Eight elements of utility are put forward which consist of “benefit satisfaction”, “promotion satisfaction”, “job satisfaction”, “enterprise satisfaction”, “management satisfaction”, “colleague satisfaction”, “relationship satisfaction” and “communication satisfaction”. Then hypotheses of influence path between SMCCM and utility are proposed. JCIA is chosen as the sample to carry out survey, which questionnaire is designed based on the likert six-point scale to avoid the middle tendency of the test samples. Data analysis is done from following angles: analysis of the structure and utility of test samples, variables analysis of SMCCM and utility, model analysis of interaction between SMCCM and utility. And then results are obtained from the analysis of elements of SMCCM and elements of utility. Conclusions: first, “rule safety knowledge” should be strengthened above all; second, “job satisfaction” should be paid more attention to; third, coal miner’s benefit should be concerned specially.     

Handling and updating uncertain information in bow-tie analysis

Bow-tie analysis is a fairly new concept in risk assessment that can describe the relationships among different risk control parameters, such as causes, hazards and consequences to mitigate the likelihood of occurrence of unwanted events in an industrial system. It also facilitates the performance of quantitative risk analysis for an unwanted event providing a detailed investigation starting from basic causes to final consequences. The credibility of quantitative evaluation of the bow-tie is still a major concern since uncertainty, due to limited or missing data, often restricts the performance of analysis. The utilization of expert knowledge often provides an alternative for such a situation. However, it comes at the cost of possible uncertainties related to incompleteness (partial ignorance), imprecision (subjectivity), and lack of consensus (if multiple expert judgments are used). Further, if the bow-tie analysis is not flexible enough to incorporate new knowledge or evidence, it may undermine the purpose of risk assessment.Fuzzy set and evidence theory are capable of characterizing the uncertainty associated with expert knowledge. To minimize the overall uncertainty, fusing the knowledge of multiple experts and updating prior knowledge with new evidence are equally important in addition to addressing the uncertainties in the knowledge. This paper proposes a methodology to characterize the uncertainties, aggregate knowledge and update prior knowledge or evidence, if new data become available for the bow-tie analysis. A case study comprising a bow-tie for a typical offshore process facility has also been developed to describe the utility of this methodology in an industrial environment.     

Is current agronomy ready to promote sustainable agriculture? Identifying key skills and competencies needed

The quest for agricultural sustainability generates the need to develop functional support schemes aimed at supplying farmers with knowledge, information and appropriate solutions, thus smoothing the transition towards sustainable agriculture (SA). In this vein, it is expected that agronomists have to play a key role, plotting the course for a sustainable farming future. Nevertheless, a critical question is whether agronomists possess the skills and competencies needed to motivate and guide this transition process. Two studies were designed to examine which clusters of agronomists’ skills and competencies determine their ability to promote SA. Study 1, using data from a sample of farmers, revealed that agronomists’ level of knowledge on issues pertaining to SA, their networking capacities, facilitation competencies, and communication skills affect their ability to guide the transition towards sustainable farm production. Study 2, drawing on data from a sample of agronomists, confirmed the pivotal role of sustainability knowledge, facilitation skills and networking competencies on the aptitude to promote SA. Both studies uncovered that agronomists display low to moderate levels of these skills. Taken together, these results point out the need to reorganize agronomic (formal and lifelong) education in order to equip agronomists with new competencies and to enable them to effectively promote SA.     

Ecological literacy and psychographics: lifestyle contributors to ecological knowledge and understanding

Knowledge and understanding about how the ecological systems of the Earth support life form the foundation for ecological literacy, which, in turn, is of critical importance for sustainability. There is widespread concern that levels of ecological literacy within many contemporary human societies are too low to enable effective decision-making about how to live sustainably. This paper presents and discusses the findings of an ecological literacy assessment of South Australian adults. The assessment tested for knowledge and understanding of ecological systems and interconnections with human society. Analyses revealed significant relationships between assessment scores and a range of value-based and behavioural characteristics. Such characteristics included the value placed on nature, time spent outdoors and in nature, involvement in nature-based activities, and perceived sources of ecological knowledge and understanding. Higher average scores were correlated with higher values accorded to involvement in outdoor activities, importance of the outdoors to enjoyment of life, importance of nature in the household, volunteer environmental activity and growing food. Higher scores were also correlated with higher education, research activities, outdoor lifestyles, place-based experiences, volunteer activities, mentors and colleagues, and books and magazines. Lower scores were achieved by those who considered media, natural disasters and environmental marketing to be major contributors to their ecological knowledge. These findings contribute to a broader study of the relationships between ecological literacy and a range of both socio-demographic and psychographic characteristics. They invite serious consideration from any society that values the participation of an informed population with the capacity to make sustainable environmental decisions.     

Long-Term Indigenous Soil Conservation Technology in the Chencha Area,Southern Ethiopia: Origin,Characteristics, and Sustainability

The purpose of this study is to examine the origin, development, and characteristics of terraces (kella), plus their potentials and determinants for sustainable use in the Chencha–Dorze Belle area of southern Ethiopia. Field surveys were conducted to determine the various parameters of the indigenous terraces and in order to collect samples for radiocarbon dating. To identify farmers’ views of the terrace systems, semi-structured interviews and group discussions were also carried out. Terraces were built and used—as radiocarbon dating proves—at least over the last 800 years. The long-term continued usage of the indigenous terraces is the result of social commitments, the structural features of the terraces, and the farmers’ responses to the dynamics of social and cultural circumstances. We dubbed that the terraces are a success story of fruitful environmental management over generations. Thus, a strong need is to preserve and develop this important cultural heritage and example of sustainable land use.     

Modelling the outcrossing between genetically modified and conventional maize with equation discovery

Many studies explore the feasibility of co-existence between genetically modified (GM) and conventional (non-GM) crops. An important research topic in these studies is the process of outcrossing, i.e., the process of gene flow via pollen flow from GM to non-GM crops. In this paper, we address a new modelling approach to define the environmentally driven processes of outcrossing for maize from existing empirical datasets. In particular, we use equation discovery methodology that combines background knowledge and empirical data from several studies. We induce models that predict the degree of outcrossing rate between the donor (GM) and the recipient (non-GM) maize field from the distance between the fields and the local wind characteristics (speed, direction and duration). This results in highly accurate models, for which both variables (distance and wind) are essential and of roughly equal importance.
