The role of perceived government style in the facilitation of self-determined and non self-determined motivation for pro-environmental behavior

Most North Americans are concerned about the environment and feel that responsibility for its protection lies primarily with government; however, no research to date has examined the influence of the government's approach toward environmental regulation on the motivation of individual citizens. According to self-determination theory, social contexts that support one's autonomy should facilitate self-determined motivation and social contexts that thwart autonomy should lead to non self-determined motivation and a sense of apathy or amotivation. In this study (n = 283), we examined the influence of perceptions of the government's approach toward environmental regulation on motivation toward the environment and frequency of self-reported pro-environmental behavior (PEB). Using structural equation modeling, we tested the hypothesis that frequency of PEB is predicted by motivation toward the environment and that motivation is predicted by the extent to which individuals perceive the government to be autonomy-supportive versus controlling in the implementation of environmental policies. The analysis revealed that perception of government autonomy-support contributed positively to autonomous motivation and negatively to amotivation, while perception of government control was positively related to both controlled motivation and amotivation. As predicted, autonomous motivation was positively, and amotivation was negatively, associated with frequency of PEB.     

The relationship between environmental activism,pro-environmental behaviour and social identity

Research on environmental activism remains poorly integrated and ill-defined and to date, there has been little examination of the relationship of environmental activism, pro-environmental behaviour and social identity. 131 students from an Australian University (M = 25.04 years old, SD = 8.17) voluntarily participated by returning an anonymous questionnaire containing an environmental activism scale, a pro-environmental behaviour scale and a social identity scale. The results revealed that while there was a significant relationship between social identity and environmental behaviour, only the citizenship component of environmental behaviour significantly predicted environmental activism. In other words, the relationship between social identity and environmental activism was indirect. This research presents the opportunity for further exploration of these relationships and to further investigate their relationship to inter-group processes.     

The relations between natural and civic place attachment and pro-environmental behavior

The relation between place attachment and pro-environmental behavior is unclear. Studies have reported that place attachment is associated both with more and less pro-environmental behavior. To help clarify this, we distinguished two dimensions of place attachment: civic and natural, and explored their respective influences on pro-environmental behavior. A community sample of residents (N = 104) from two proximate towns with different environmental reputations reported the strength of their civic and natural place attachment, their performance of various pro-environmental behaviors, and a number of sociodemographic characteristics. Regression analyses revealed that natural, but not civic place attachment predicted pro-environmental behavior when controlling for the town, length of residence, gender, education and age. This demonstrates that research and theory on place attachment should consider its civic and natural dimensions independently.     

Environmental concern, attitude toward frugality, and ease of behavior as determinants of pro-environmental behavior intentions

This study investigates relations between environmental concern, attitude toward frugality, perceived ease of behavior, and stated intentions to engage in four different types of pro-environmental behavior, i.e., reductions in electricity and gas use, garbage, and automobile use, using data from 341 Japanese respondents. Environmental concern, attitude toward frugality and perceived ease of implementation were considered possible determinants. A structural equation analysis indicated that perceived ease of implementation had effects for all of the pro-environmental behaviors. It also indicated that environmental concern had a positive effect solely for garbage reduction, while attitude toward frugality had positive effects for gas and electricity reduction. For automobile use reduction, neither environmental concern nor attitude toward frugality had significant effects. The relationship between attitude toward frugality and mottainai, that is a Japanese concept indicating respect for resources, is then discussed, and it is suggested that educating people to have not only a high level of environmental concern but also a positive attitude toward frugality would be an effective means of promoting pro-environmental behavior.     

Relation between management's behavioural intentions toward the environment and environmental actions

Drawing on Ajzen's Theory of Planned Behaviour, this paper analyses whether there is a relation between management's behavioural intentions toward an environmental problem and the company's specific actions in this area, and also considers the impact of the company size on these actions. For the data, a questionnaire was sent to 184 managers employed in industrial companies located in Spain which belonged to the automobile industry. The empirical analysis produces positive and significant regression coefficients and provides support for the hypotheses proposed. Specifically, the results show that the environmental actions carried out in the company respond at least in part to management's behavioural intentions toward these issues and the size of the firm.     

The influence of place attachment, and moral and normative concerns on the conservation of native vegetation: A test of two behavioural models

This study examines the influence of place attachment, values, beliefs and personal norms about environmental action on the conservation of native vegetation in two primary production settings in South Australia. We use regression and multiple mediation analyses to test a base model of pro-environmental behaviour which includes variables from value-belief-norm (VBN) theory and then compare it to an expanded model which includes the same variables and five dimensions of place attachment. The expanded model including place attachment explained up to twice the amount of variance in native vegetation planting than the base model when controlling for all variables preceding behaviour, but the overall explanatory power was low (<22%). Place attachment had a stronger influence on the antecedents of behaviour compared with the behaviour itself, particularly nature bonding which was a significant moderate predictor of both personal norms and awareness of consequences in the two study regions. We assert that place attachment has statistically significant direct and indirect effects on variables included in VBN theory. Future studies may reveal stronger effects in settings where there are fewer resource and monetary costs associated with pro-environmental behaviour.     

The relationships between awareness of consequences,environmental concern,and value orientations

Different people become engaged in environmental issues and perform proenvironmental behavior because they believe in and are concerned about adverse consequences of environmental problems for themselves (egoistic beliefs and concerns), others (social-altruistic beliefs and concerns), or the biosphere (biospheric beliefs and concerns). These different beliefs and concerns are assumed to derive from corresponding value orientations. Yet, distinguishing egoistic, social-altruistic, and biospheric value orientations has proved difficult in previous research. Based on a survey of 494 Swedish residents between 18 and 69 years old, the present study provides empirical support for that egoistic, social-altruistic, and biospheric environmental concerns are related to corresponding awareness-of-consequences beliefs, and that both the beliefs and environmental concerns are related to the three value types power, benevolence, and universalism.     

Relationships between net primary productivity and stand age for several forest types and their influence on China's carbon balance

Affected by natural and anthropogenic disturbances such as forest fires, insect-induced mortality and harvesting, forest stand age plays an important role in determining the distribution of carbon pools and fluxes in a variety of forest ecosystems. An improved understanding of the relationship between net primary productivity (NPP) and stand age (i.e., age-related increase and decline in forest productivity) is essential for the simulation and prediction of the global carbon cycle at annual, decadal, centurial, or even longer temporal scales. In this paper, we developed functions describing the relationship between national mean NPP and stand age using stand age information derived from forest inventory data and NPP simulated by the BEPS (Boreal Ecosystem Productivity Simulator) model in 2001. Due to differences in ecobiophysical characteristics of different forest types, NPP-age equations were developed for five typical forest ecosystems in China (deciduous needleleaf forest (DNF), evergreen needleleaf forest in tropic and subtropical zones (ENF-S), deciduous broadleaf forest (DBF), evergreen broadleaf forest (EBF), and mixed broadleaf forest (MBF)). For DNF, ENF-S, EBF, and MBF, changes in NPP with age were well fitted with a common non-linear function, with R(2) values equal to 0.90, 0.75, 0.66, and 0.67, respectively. In contrast, a second order polynomial was best suitable for simulating the change of NPP for DBF, with an R(2) value of 0.79. The timing and magnitude of the maximum NPP varied with forest types. DNF, EBF, and MBF reached the peak NPP at the age of 54, 40, and 32 years, respectively, while the NPP of ENF-S maximizes at the age of 13 years. The highest NPP of DBF appeared at 122 years. NPP was generally lower in older stands with the exception of DBF, and this particular finding runs counter to the paradigm of age-related decline in forest growth. Evaluation based on measurements of NPP and stand age at the plot-level demonstrates the reliability and applicability of the fitted NPP-age relationships. These relationships were used to replace the normalized NPP-age relationship used in the original InTEC (Integrated Terrestrial Ecosystem Carbon) model, to improve the accuracy of estimated carbon balance for China's forest ecosystems. With the revised NPP-age relationship, the InTEC model simulated a larger carbon source from 1950-1980 and a larger carbon sink from 1985-2001 for China's forests than the original InTEC model did because of the modification to the age-related carbon dynamics in forests. This finding confirms the importance of considering the dynamics of NPP related to forest age in estimating regional and global terrestrial carbon budgets.     

A mineral commodity life-cycle?: Relationships between production,price and economic resources

The production, price and economic resources profiles of a number of mineral commodities are examined and consideration is given to the theory that such profiles can be related to one another within the framework of a life-cycle model of development. While the behaviour of some of the commodities examined appears to lend support to the theory, that of others reveals fundamental problems with its underlying assumptions. It is concluded that, while the demand for a mineral commodity in specific uses may indeed manifest cyclical tendencies, as a general behavioural theory and as a basis for resource estimation the life-cycle model applied to minerals is of little value.
