Conversion of native forests to turfgrass-dominated residential landscapes under a wide range of management practices results in dramatic changes to vegetation and soils, which may affect soil carbon storage. To better understand the effects of landscape conversion and management on soil carbon, we conducted a study on residential properties in the Valley and Ridge physiographic province of southwest Virginia to compare soil carbon storage and dynamics between turfgrass landscapes and the surrounding mixed oak forests from which they were developed. Sixty-four residential properties ranging from 5 to 52 years since site development were investigated. Soil samples were collected from lawns and adjacent forest stands to a depth of 30 cm and analyzed for carbon and nitrogen content. Additional measurements taken were soil bulk density, temperature, moisture, and total soil CO₂ efflux rate. Homeowners participating in the study completed a survey on their lawn management practices so that the effects of specific practices (e.g. fertilization) and intensity levels on carbon dynamics could be analyzed. Also included in the survey were 11 questions regarding the homeowners' commitment to the environment. Homeowners were assigned an environmental commitment score based on their responses which was compared with lawn management practices in order to identify any connection between environmental attitude and lawn management practices. Total soil carbon content to 30 cm depth of lawn (6.5 kg C/m²) and forest (7.1 kg C/m²) marginally differed (P=0.08); however, lawn soil contained significantly greater C than forest soil at the 20-30 cm depth (0.010 vs. 0.007 g C/cm³, P=.0137). There was a weak negative relationship between carbon in the lawn and time since development at the 20-30 cm depth (P=0.08), but no significant relationship between time and C content at shallower depths. We found a positive relationship between time since development and percent C of lawn at the 0-5 cm depth (P=0.04), whereas there was a negative relationship with percent C and time at the 20-30 cm depth (P=0.03). Based on the homeowner survey, we found a positive correlation between lawn fertilization frequency and both lawn nitrogen content (P=.07) and lawn carbon content (P=.0005) in the top 0-5 cm of soil. Nitrogen content was greater in lawn than forest soil at the 0-5 cm depth (0.0025 vs. 0.0018 g/cm³³, P<.0001) and the 5-10 cm depth (0.0013 vs. 0.0009 g/cm³, P <.0001). There was a positive relationship (P=0.059) between overall environmental commitment score and level of management intensity. Higher environmental commitment (EC) score corresponded with a higher level of management intensity (fertilizer and pesticide use). Our results indicate that converting unmanaged Appalachian hardwood forest into managed, turf-grass dominated residential homesites results in similar soil organic concentration and depth distribution as the previous forest within a short period of time following development. Although total soil carbon does not differ between lawn and forest, lawn may develop greater density at 20-30cm depth over time. Fertilization enhances carbon and nitrogen content in the upper 0-5cm in lawns. Homeowners who feel that they are more strongly committed to the environment are more likely to apply higher levels of fertilizer to their lawn. / Master of Science

This thesis explores the relationship between place attachment and pro-environmental behaviour expressed by visitors to Point Pelee National Park. Place attachment, the functional, cognitive and emotional bond with a place, may play a role in promoting environmentally responsible behaviours. This may be especially true of place-specific pro-environmental behaviours; however place attachment may also have a "carry-over" effect in that its impact on individuals' self identity may also foster pro-environmental behaviour in individuals' every day lives. <br /><br /> An exploration of these relationships was achieved, first by measuring the intensity of place attachment and pro-environment behavioural intentions expressed by visitors to Point Pelee National Park. This was followed by an examination of the relationship between these two constructs using correlation analysis and structural equation modeling. Data was collected with a mail-based self-completed questionnaire. A quota sample of visitors to Point Pelee National Park was utilized. A response rate of 32% (<em>n</em> = 355) was achieved. <br /><br /> The relationship between place attachment and pro-environmental intentions was explored further through the measurement of several related variables. These factors include place satisfaction (based on an appraisal of nature, social and activity-based environments), motivation for visiting the park (related to social interaction and nature observation, as well as activity-based and learning opportunities), distance between the park and visitors' residences, membership in environmental organizations, and visitation patterns including visitation to the park during childhood, length of affiliation with the park, length of visit to the park, and frequency of visitation to the park. Theoretical and empirical research suggests that these factors may affect place attachment, pro-environment behavioural intentions, and/or the relationship between these two constructs. <br /><br /> Study results found positive associations between place attachment and all of these variables with the exception of visitation motives associated with learning and engaging in a favourite activity. The strongest predictive relationships were observed with anti-substitution (the inability of an individual to substitute the park for another destination because of a lack of resources such as time or money or a lack of awareness of comparable sites) followed by frequency of visits to the park; park commitment (based on Friends group membership and donations of time and money to the Friends group); Friends of Point Pelee (FoPP) membership; and park relationship (which was based on visitation to the park as a child and length of affiliation); and, satisfaction with the park. <br /><br /> Results support the proposition that place attachment has a strong positive association with both park-specific pro-environment behavioural intentions (e. g. , Write letters in support of Point Pelee N. P. and similar protected areas) as well as general pro-environment behavioural intentions (e. g. , Pay extra for transportation if it is environmentally-friendly). Place attachment strongly predicted park-specific, and moderately predicted general pro-environmental intentions. A number of other variables had an indirect effect on park-specific intentions; notable effects were demonstrated by frequency of visits; park relationship; visitation to the park as a child; place satisfaction; social satisfaction; FoPP membership; and, park commitment; anti-substitution. These affects were mediated by place attachment. After place attachment the strongest predictors of park-specific intentions were anti-substitution; frequency of visits; park commitment; and, general environmental commitment (which was based on membership in an environmental organization and donations of time and money to that organization). <br /><br /> Place attachment was not the only direct predicator of general pro-environmental intentions; general environmental commitment and membership in an environmental organization also directly predicted general pro-environmental intentions. Notable indirect effects, mediated by place attachment were produced by frequency of visits; park relationship; FoPP membership; park commitment; and anti-substitution. The strongest predictors of general pro-environmental intentions were general environmental commitment, followed by place attachment, membership in an environmental organization, and frequency of park visitation. <br /><br /> These findings correspond with much of the literature published on place attachment formation and the development of pro-environmental behaviours. The most notable contribution of this study is its comparison of place attachment's impact on general versus place-specific behaviours, and the role that several related variables play in this relationship.

A adoção de práticas sustentáveis desde à produção de alimentos até o consumo final tem sido mais frequente nos últimos anos. Essas práticas sustentáveis estão embasadas na promoção do desenvolvimento sustentável, sem prejudicar as gerações futuras da humanidade. Nesse contexto, os proprietários das agroindústrias familiares se deparam com diversos desafios quando se trata da diminuição de impactos ambientais e, em consequência, da promoção do desenvolvimento rural sustentável. A adoção de práticas sustentáveis é resultado da compreensão da consciência ambiental e dos valores humanos, os quais desencadeiam as atitudes pró-ambientais e, assim, resulta em um comportamento ecológico. Neste sentido, objetivou-se analisar a influência da consciência ambiental e dos valores humanos sobre as atitudes pró-ambientais dos proprietários das agroindústrias familiares vinculadas ao PEAF/RS. Os dados foram coletados por meio da aplicação de questionário, com quatro grupos de questões (perfil das agroindústrias familiares e atitudes pró-ambientais, Escala NEP, perfil socioeconômico, Escala Schwartz). A amostra corresponde aos 105 proprietários de agroindústrias familiares do Rio Grande do Sul. Os dados foram analisados utilizando estatística descritiva, analise fatorial e correlação. Os resultados apresentam que mais da metade da amostra é composta por adultos, com grau de escolaridade elevado e com formação em cursos voltados para a gestão da agroindústria Além disso, 37% das agroindústrias familiares têm um tempo de existência entre um a cinco anos, com mão de obra familiar e com atividades predominantes em olericultura, bebidas e panificados, nas cidades de Caxias do Sul, Santa Maria e Lajeado. A aplicação das escalas, demonstrou que os proprietários das agroindústrias familiares possuem um nível elevado de consciência ambiental, com predominância nos valores humanos de ordem superior “conservação” e “autotranscendência”. Tais resultados revelam uma tendência de possuir um comportamento ecocêntrico e altruísta, conforme a Escala NEP e Schwartz, respectivamente. Além disso, observou-se que as agroindústrias familiares têm atitudes pró-ambientais, as quais são implantadas e praticadas pela agroindústria. De modo geral, 40% dos proprietários das agroindústrias acreditam que o empreendimento tem mais de 80% de atividades pró-ambientais, tais como, o uso de embalagens recicláveis, a prática de conscientização ambiental, a economia de energia, o uso correto do descarte dos resíduos sólidos. Porém não foi encontrado correlação entre as escalas e as atitudes pró-ambientais. Portanto, entende-se que esses resultados auxiliam as esferas federativas na formulação de uma política de benefícios, motivando-os aqueles que possuem mais adequação à preservação ambiental e incentivando outros proprietários a praticarem mais ações ambientais. / The adoption of sustainable practices from food production to final consumption has been more frequent in recent years. These sustainable practices are based on the promotion of sustainable development, without harming future generations of humanity. In this context, the owners of family agroindustries face several challenges when it comes to reducing environmental impacts and, as a consequence, promoting sustainable rural development. The adoption of sustainable practices is the result of an understanding of environmental awareness and human values, which triggers pro-environmental attitudes and thus results in ecological behavior. In this sense, the objective was to analyze the influence of environmental awareness and human values on the pro-environmental attitudes of the owners of family agroindustries linked to PEAF/RS. Data were collected through the application of a questionnaire, with four groups of questions (profile of family agroindustries and pro-environmental attitudes, NEP Scale, socioeconomic profile, Schwartz Scale). The sample corresponds to the 105 owners of family agroindustries in Rio Grande do Sul. Data were analyzed using descriptive statistics, factorial analysis and correlation. The results show that more than half of the sample is composed of adults, with a high level of education and training in courses aimed at the management of agribusiness. In addition, 37% of family agroindustries have a life span of between one and five years, with family labor and predominant activities in olericultura, beverages and baked goods, in the cities of Caxias do Sul, Santa Maria and Lajeado The application of the scales, showed that the owners of the family agroindustries have a high level of environmental awareness, with a predominance of human values of higher order "conservation" and "self-transcendence". These results reveal a tendency to have an ecocentric and altruistic behavior, according to the NEP and Schwartz Scales, respectively. In addition, it was observed that family agroindustries have pro-environmental attitudes, which are implemented and practiced by the agroindustry. In general, 40% of the owners of agroindustries believe that the enterprise has more than 80% of pro-environmental activities, such as the use of recyclable packaging, the practice of environmental awareness, energy saving, the correct use of waste of solid waste. However, no correlation was found between the scales and the pro-environmental attitudes. Therefore, it is understood that these results help federative spheres in the formulation of a benefits policy, motivating those that are more adequate to environmental preservation and encouraging other owners to practice more environmental actions.

Esta dissertação tem como objetivos verificar as propriedades psicométricas da Escala de Atitudes Ambientais para Crianças (EAAC; adaptada de Leeming, Dwyer, Porter & Bracker, 1995) e da Escala Infantil de Satisfação com o Ambiente (EISA; criada pelo Grupo de Pesquisa em Psicologia Comunitária); verificar a associação entre bem-estar pessoal (mensurado através da Personal Wellbeing Index) e variáveis ambientais e analisar as atitudes ambientais das crianças da amostra. Foram realizados três estudos, com 1746 crianças (53,5% meninas) com idades entre 8 e 13 anos (M = 10.17; DP = 1.492) residentes de Porto Alegre (54.9%) e do interior do Rio Grande do Sul (45.1%). Os resultados do primeiro estudo indicaram que os instrumentos analisados, EAAC e EISA, apresentam bons índices de ajuste para a amostra pesquisada quando da realização na análise fatorial (exploratória e confirmatória). Com relação ao segundo estudo, as análises de regressão multivariadas indicaram que o PWI é explicado pelos itens da EAAC em 11.5% e pelos itens da EISA em 14.4%. Estão associoados ao bem-estar pessoal: a satisfação com o ambiente residencial e escolar, as atitudes ambientais que envolvem a família, o contato com a natureza e o contato com animais. O terceiro estudo buscou verificar se existem diferenças entre grupos para as atitudes ambientais e os resultados indicaram que as crianças que estudam em escolas públicas, assim como as crianças que vivem em cidades do interior e as crianças mais novas, tendem a desenvolver mais atitudes favoráveis ao ambiente. Em uma etapa qualitativa do terceiro estudo, as crianças mencionaram preocupar-se com a crise ambiental e apresentaram atitudes ambientais voltadas a ações cotidianas e de ativismo. / This dissertation aims to evaluate the psychometric properties of the Children’s Environmental Attitudes Scale (EACC; adjusted from Leeming, Dwyer, Porter & Bracker, 1995) and of the Children’s Environment Satisfaction Scale (EISA; developed by the Grupo de Pesquisa em Psicologia Comunitária); to verify the association between personal wellbeing (measured by the Personal Wellbeing Index School Children) and environmental variables; and to analyze the environmental attitudes of the children in the sample. There were conducted three studies with 1746 children (53.5% girls) aged between 8 and 13 years old (M = 10.17; SE = 1.492) residents on Porto Alegre (54%) and on inner cities of Rio Grande do Sul State (45.1%). The results of the first study indicated that EAAC and EISA scales had good overall fit rates when exploratory and confirmatory factorial analyses were performed. In the second study, multivariate regression analysis showed that the Personal Wellbeing Index is predicted in 11.5% by the EACC items and in 14.4% by the EISA. The personal wellbeing is associated to: satisfaction with school and residence environment; family environmental attitudes; contact with animals and contact with nature. The third study aimed to check if there are differences of environmental attitudes between the groups. Outcomes indicated that children of public schools, children of inner cities and younger children tend to develop more favorable environmental attitudes. During the qualitative stage of the third study, children mentioned that they worry about the environmental crisis and presented environmental attitudes related to daily actions and activism behaviors.

This article examines the relationships among adolescent environmental behaviors and self-efficacy, knowledge, and attitudes. It was hypothesized that adolescents who demonstrate more proenvironmental attitudes are more likely to demonstrate proenvironmental behaviors. It was further hypothesized that perceived self-efficacy would have a moderating effect on the environmental attitude-behavior relationship in that the relationship between proenvironmental attitudes and behaviors would be stronger among adolescents with high levels of self-efficacy. Participants were 848 students from three academically achieving high schools on the West coast. Hierarchical regression analyses were used for all subsequent analyses. Results indicated that proenvironmental attitudes significantly predicted proenvironmental behaviors and that environmental knowledge was a significant moderator for the relationship between environmental attitudes and environmental behaviors. This was especially true for males.

This thesis examines whether or not differences in people’s water conservation attitudes, political party orientation, severity of drought, and attention to drought news affect their engagement in water conservation behavior during a time of continued water shortage. Previously, it has been found that attitudes are predictive of intentions that relate to behaviors (e.g., Dietz et al. 2005). Democrats have been shown to be more pro-environmental then Republicans (e.g., Dunlap et al. 2000). It has also been found that severity of drought is positively related with environmental concern (e.g., Accury and Christianson 1990), and access to news information is directly related to willingness to take action (e.g., Johnson and Scicchitano 2000). However, during a time of drought, what is the relationship between individual water conservation attitudes and behaviors? Do conventional understandings of political party orientation and water conservation behaviors hold during a time of drought? Do those living in counties that experience more severe drought engage in more water conservation behaviors? Do those who pay more attention to drought news engage in more water conservation behaviors? Using data from Georgia’s 2007 Peach State Poll, I explore the answers to these questions. I examine how water conservation attitudes (Model 1), political party orientation (Model 2), drought severity (Model 3), attention to drought news (Model 4), sociodemographics, controls, and other factors from models 1-4 (Model 5) influenced water conservation behavior during the 2007 Georgia drought. Results indicate that differences in people’s water conservation attitudes, political party orientation, drought severity, and attention to drought news did not significantly affect their water conservation behavior during the 2007 drought. However, race, class, and gender variables in the full model did have a significant effect, which seems to suggest that one’s location in the social stratification system affects their opportunities to engage in water conservation behavior. Therefore, environmental policy issues should not be considered apart from social issues. The fundamental theoretical significance of the following research is that we affect and are in turn affected by the biophysical world in a dialectic fashion. Recognizing the quality, quantity, and interrelatedness of nature-society relationships is essential for future research.

 The majority of Americans profess to hold pro-environmental attitudes and intend to engage in environmentally friendly behavior. Yet their actions tell a different story. The goal of this study was to explain the gap between widely held pro-environmental attitudes and the lack of corresponding individual and collective behavior. Using both quantitative and qualitative methods and applying the principles of grid-group cultural theory, cognitive sociology, and identity theory I examined the meanings people ascribe to the environment, how they think about behavior relative to the environment, and justifications for the performance of environmentally significant behavior. I administered an on-line survey to a nationally representative sample of individuals. By applying grounded theory methods to the textual data generated by open-ended survey questions I developed a model of environmentally signficant behavior which describes the underlying factors that influence the performance of pro-environmental behavior. Individuals develop environmental socio-cognitive schemas based on the ways in which they use the six cognitive acts (perceiving, focusing, classifying, signifying, remembering, and timing) in thinking about the environment. They use these environmental socio-cognitive schemas to filter and interpret environmental discourse, construct a body of environmental knowledge, and guide environmentally significant behavior. According to this study, the explanatory link between pro-environmental attitudes and pro-environmental behavior lies in the concept of proximity. Performance of pro-environmental behavior is driven by the distance individuals perceive themselves to be from environmental issues. Attitudes toward the environment remain abstractions whereas behavior is situational. Individuals from different cultural groups hold different ideas about the relationship between humans and nature, the extent and severity of environmental issues, and how those issues should be addressed. The findings from this study provide a foundation for developing effective strategies for influencing environmentally significant behavior. This study is important because environmental issues are real, their potential impact is substantial, and time is of the essence in addressing them.

The most devastating effects of climate change may be avoided if humans reduce activities that produce greenhouse gases and engage instead in more sustainable ecological behaviors. The current mixed methods study of 279 undergraduate students explored whether environmental worldview, belief in climate change, knowledge of climate change, personal efficacy, and intention to address climate change influenced participants’ engagement in ecological behavior. Results indicated that those with a stronger intention to address climate change and a more ecocentric worldview reported significantly more ecological behavior. Next, the study examined whether participants’ intentions to address climate change mediated the relationship between their belief in climate change and engagement in ecological behavior and whether intentions mediated the relationship between efficacy and ecological behavior. Intentions to address climate change did not mediate the relationship between belief and ecological behavior but fully mediated the relationship between efficacy to address climate change and ecological behavior.
