Still Waters Run Deep: Landscaping Practices, Community Perceptions, and Social Indicators for Stormwater Nonpoint Source Pollution Management in Manatee County, Florida

Persaud, Ann Rebecca 17 March 2014 (has links)
Stormwater nonpoint source pollution (NPSP) is a result of diffuse sources of pollutants transported by rainfall and surface runoff into stormwater ponds and drainage systems before percolating into the ground. In particular, the nutrients found in fertilizers, pesticides, and herbicides applied in excess by homeowners and landscapers can cause a range of issues in stormwater ponds from fish kills to eutrophication. As a result, Manatee County, Florida has issued a fertilizer ordinance with best management practices (BMPs) and a fertilizer black out period to reduce NPSP. This study is aimed at capturing the perceptions of residents which affect stormwater NPSP through their behaviors, awareness, and knowledge. Interviews, surveys,and observational data were used to establish social indicator scores, gather qualitative data, and evaluate outreach efforts surrounding the Manatee County fertilizer ordinance and the function stormwater ponds in Lakewood Ranch. Results showed that residents substantially lacked awareness of the fertilizer ban, ordinance and grass clipping violation fine. Outreach questions revealed that 69% of residents had not seen any materials related to the ban. While residents' feelings generally ranged from neutral to positive with regard to shoreline and aquatic plants, they remained resistant to the actual installation of the plants. The results also indicated that residents were well aware of the purposes shoreline plants serving as barriers and nutrient filters. In addition, Key Informant interviews revealed that while residents understood the environmental consequences of their actions, they maintained their behavior to adhere to deeply rooted social norms.

Environmentální gramotnost studentů Učitelství pro 1. stupeň základní školy a možnosti jejího zjišťování / Environmental literacy of pre-service teachers of primary school and possibilities of its assessment

KROUFEK, Roman January 2016 (has links)
In recent decades, the environmental literacy and its output dimension, responsible environmental behavior represents an important construct, which is studied by a number of researchers from many countries. In this dissertation, firstly we introduce environmental literacy from a theoretical point of view, then the development of approaches to this construct as well as a review of research in past decades. In our own research, we initially sought for a suitable research instrument to be used to identify and measure selected aspects of environmental literacy among pre-service primary teachers. The research tool was found in a combination of Nature relatedness scale and Environmental Behavior scale, supplemented by data collection using concept mapping with the central concept of the greenhouse effect. The variables that affect various aspects of environmental literacy were found on a sample of more than five hundred of the respondents using this tool and its modifications. Higher values were found within the respondents who were engaged in regular environmentally-themed activities, respondents from villages up to 100 inhabitants and the older respondents. The nature relatedness has moderately positive effect on the responsible environmental behavior, cognitive component of environmental literacy does not have such influence. The international comparison showed lower results from the respondents from Slovakia in comparison with students from the Czech Republic and Turkey. Nature relatedness scale proved to be useful for measuring a particular element of the affective component of environmental literacy across countries, by contrast, Environmental behavior scale reached low psychometric results on all foreign respondents.

No. of bitstreams: 1 silva_ra_dr_rcla.pdf: 3544993 bytes, checksum: 397882c9847d86efebcd151744bc129f (MD5) Previous issue date: 2018-05-28 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / Na escala global, a intensificação das atividades antrópicas vem provocando mudanças prejudiciais aos ecossistemas naturais, como a superexploração dos recursos, supressão de florestas e redução da biodiversidade. Tais efeitos afetam diretamente a qualidade de vida dos seres humanos, inviabilizando a provisão sustentável de bens e serviços que a natureza pode promover, chamados Serviços Ecossistêmicos (SE). Em áreas de alta aptidão agrícola, a demanda por terras acelera a modificação das paisagens. A regulamentação desta demanda é determinada por tomadores de decisão que, por sua vez, são influenciados por suas preferências culturais, pelo mercado e pelas características ambientais e físicas da região. Visando estimular a restauração de florestas e consequentemente a manutenção da provisão de SE e a conservação da biodiversidade, esta tese objetivou entender como o conceito de SE pode auxiliar na elaboração de políticas, programas, projetos e ações ambientais em áreas de alta pressão agropecuária. Esta pesquisa foi desenvolvida na região do Pontal do Paranapanema, à oeste do estado de São Paulo, Brasil. Esta região é marcada por um passado de grilagens de terra, que acelerou o processo de desmatamento, incorporando a pecuária nos seus sistemas de produção e, recentemente, a cana-de-açúcar, principalmente em grandes propriedades rurais. Ainda, esta região concentra uma grande quantidade de assentamentos da reforma agrária. Foi verificado o status de conservação da cobertura florestal no interior das propriedades rurais e diagnosticado o alto passivo de florestas de acordo a lei brasileira de Proteção da Vegetação Nativa (LPVN). Com base nesse resultado, foram propostas diferentes estratégias de adequação ambiental com base no tamanho das propriedades. A percepção de SE e o comportamento ambiental de dois grupos de proprietários rurais (assentados e fazendeiros) foi diagnosticada por meio de entrevistas semiestruturadas, e verificou-se que as pessoas percebem mais SE nos ambientes com floresta e água, embora estes ambientes não façam parte de suas rotinas. No geral, os fazendeiros apresentaram maior percepção dos SE que os assentados, o que pode ser atribuído à sua maior escolaridade, contato com a natureza e tempo de domínio da terra. Por fim, ficou evidenciado que o conceito de serviços ecossistêmicos pode fortalecer instrumentos de conservação e restabelecimento da biodiversidade, tomando como base a adequação ambiental das propriedades à legislação vigente. / In the global scale, the intensification of human activities has been causing negative effects on natural ecosystems, such as overexploitation of resources, suppression of forests and reduction of biodiversity. These effects affect directly the quality of life of human beings, making it impossible to maintain a sustainable provision of goods and services from nature, the so called Ecosystem Services (ES). In areas with high agricultural aptitude, demand for land accelerates landscape modification. Regulamentation of such demand is determined by decision-makers who, in turn, are influenced by culture, the market, environmental and physical characteristics of the region. Aiming at forest restoration and, consequently, ES maintenance and biodiversity conservation, this research intended to identify the potential application of the ES concept in the formulation of environmental policies, programs, projects and actions in areas of high agricultural aptitude. This research was developed at Pontal do Paranapanema, a region in the western of São Paulo State, Brazil. This region is marked by a past of land encroachments, which pushed the process of deforestation, incorporating livestock in its production systems and, more recently, sugar cane was included mainly in large rural properties. Still, this region concentrates a great amount of settlements from land reform. The state of conservation of forests was verified within the rural properties, as well as their legal deficit according to the Brazilian Law of Protection of Native Vegetation. Based on these results, different strategies to pursue environmental adequacy were proposed according to property size. The perception of ES and the environmental behavior of two groups of rural landowners were diagnosed through semi-structured interviews, and it was verified that people perceived more ES in forest and water environments, even though such environments are not part of their daily routines. In general, farmers have a greater perception of ES than settled farmers, which can be attributed to their higher education, contact with nature and duration of land tenure. Lastly, it was evidenced that the concept of ES can strengthen instruments for conservation and restoration of biodiversity, based on the environmental adequacy of rural properties to the current legislation.

Os dados foram obtidos, mediante entrevistas semiestruturadas com 40 produtores rurais de cada município e, com base nestes dados, foram calculados os índices de qualidade de vida, capital social e ambiental, para, então, calcular o índice de sustentabilidade. Os produtores rurais demostraram um tempo de atuação nas atividades agropecuárias que variaram de 10 a 70 anos de trabalho no campo. Nos municípios do Sertão paraibano estudados, verificou-se que, segundo os produtores rurais, as atividades pecuárias que apresentam melhor desempenho econômico são a caprinocultura, a apicultura e a bovinocultura. Dentro das atividades agrícolas, destacam-se a fruticultura e a cultura de sequeiro. Em relação ao índice de qualidade de vida, todos os municípios foram caracterizados como médio. Para o índice de capital social, apenas Triunfo foi definido como baixo nível, os demais foram classificados como médio. O município de Santa Helena apresentou índice ambiental para os produtores rurais de médio nível de preservação, sendo que as caracterizações dos demais municípios foram de baixo nível. O nível de sustentabilidade dos produtores rurais, dos municípios de São João do Rio do Peixe, Santa Helena e Poço de José de Moura foi definido como médio. O município de Triunfo foi classificado como de baixo nível de sustentabilidade dos produtores rurais o qual teve contribuição negativa da baixa preservação ambiental e pequena participação social dos produtores. / The objective of this study was to evaluate the level of sustainability of rural producers in four municipalities of Sertão da Paraíba, analyzing the contribution of the indicators regarding quality of life, social capital and environmental preservation of producers. The data were obtained through semi-structured interviews with 40 rural producers from each municipality and, based on these dataof, indices of quality life, social and environmental capital were calculated, in order, to calculate the sustainability index. The rural producers demonstrated a time of performance in agricultural activities that varied from 10 to 70 years of work in the field. In the municipalities of Sertão, in the state of Paraíba, Brazil, it was verified that, according to the rural producers, the livestock activities that present the best economic performance are goat breeding, beekeeping and cattle breeding. Within the agricultural activities, stands out the fruticulture and the dryland culture. In relation to the quality of life, index all municipalities were characterized as medium. For the social capital, index only Triunfo was defined as low level, the others were classified as average. The municipality of Santa Helena presented an environmental index for the rural producers of medium level of preservation, and as characterizations of the other municipalities were low level. The level of sustainability of rural producers, in the municipalities of São João do Rio do Peixe, Santa Helena and Poço de José de Moura was defined as medium. The municipality of Triunfo was classified as low level of sustainability of the rural producers, which had a negative contribution of the low environmental preservation and small social participation of the producers.

The choice of the county was due to a detection (made by IBAMA technicians and reported in a Technical Report) -which showed that the dangerous Snail is already spreading in 14 of 17 districts of the county-, as well as the support given by Parnamirim s Town Hall, with the implementation of the Plan Control/Eradication of the African s Huge Snail, widely known as Day C . The research tools used in that research consists of questionnaires with all sorts of questions. The results show us that most of the residents were feeling threatened by the presence of the animal as well as having had a little participation in the fight against the animal. It also shows us that residents believe that organizations (Town Hall, IBAMA and Local Community) involved are able to solve the problem and believe that the amounts which organization are supposed to take 89,4 %, 87,6% and 80,8%, in that order. As we check the results, we notice in 95%, the variety of threaten and frequency reunion and participation level / O objetivo deste trabalho foi investigar os fatores influenciadores da participa??o da popula??o na tomada de decis?o ambiental, no munic?pio de Parnamirim, no Rio Grande do Norte, a partir da vis?o dos seus moradores, tendo como enfoque o Programa de Controle/Erradica??o do Caramujo Gigante Africano (Achatina fulica), implantado de forma conjunta IBAMA x Prefeitura Municipal. A metodologia aplicada constou de uma pesquisa amostral, tipo Survey, com 395 entrevistas de pessoas do munic?pio, com idade m?nima de 18 anos, de um universo de 124.690 habitantes. A escolha do munic?pio deveu-se a detec??o, feita por t?cnicos do IBAMA, atrav?s de um Relat?rio T?cnico, mostrando que o caramujo j? se encontrava disseminado em 14 dos 17 bairros existentes no munic?pio e, tamb?m, pelo apoio dado pela Prefeitura Municipal de Parnamirim, com a instala??o do Programa de controle/erradica??o do caramujo, mais comumente conhecido como o dia C . O instrumento de pesquisa utilizado foi um question?rio com perguntas abertas e fechadas. Em termos de associa??o entre vari?veis foi poss?vel se verificar signific?ncia, em n?vel de 95%, das vari?veis independentes AMEA?A (opini?o do entrevistado quanto ao n?vel de amea?a causada pela presen?a do caramujo) e FRREU (freq??ncia de participa??o dos entrevistados nas reuni?es ocorridas entre o IBAMA x Prefeitura) com a vari?vel dependente NIPAR (opini?o do entrevistado quanto ao seu n?vel de participa??o do programa de combate ao caramujo). Pressup?e-se, portanto, que as a??es de fiscaliza??o e monitoramento (comando-controle) devem ser integradas a um processo consistente de conscientiza??o ambiental da popula??o buscando se estabelecer aspectos atitudinais no cidad?o, de forma que as pessoas, atrav?s de um mecanismo de educa??o ambiental (formal ou informal), bem como, de um constante monitoramento, passem a dar maior import?ncia ao programa de combate ao caramujo, buscando um comportamento ambiental adequado, uma vez que os entrevistados somente aumentaram o seu n?vel de participa??o a partir do momento em que se sentiram amea?ados e participaram das reuni?es desenvolvidas pelo IBAMA e Prefeitura Municipal de Parnamirim

The Interpersonal Determinants of Green Purchasing: An assessment of the empirical record

January 2012 (has links)
abstract: This study investigates how well prominent behavioral theories from social psychology explain green purchasing behavior (GPB). I assess three prominent theories in terms of their suitability for GPB research, their attractiveness to GPB empiricists, and the strength of their empirical evidence when applied to GPB. First, a qualitative assessment of the Theory of Planned Behavior (TPB), Norm Activation Theory (NAT), and Value-Belief-Norm Theory (VBN) is conducted to evaluate a) how well the phenomenon and concepts in each theory match the characteristics of pro-environmental behavior and b) how well the assumptions made in each theory match common assumptions made in purchasing theory. Second, a quantitative assessment of these three theories is conducted in which r2 values and methodological parameters (e.g., sample size) are collected from a sample of 21 empirical studies on GPB to evaluate the accuracy and generalize-ability of empirical evidence. In the qualitative assessment, the results show each theory has its advantages and disadvantages. The results also provide a theoretically-grounded roadmap for modifying each theory to be more suitable for GPB research. In the quantitative assessment, the TPB outperforms the other two theories in every aspect taken into consideration. It proves to 1) create the most accurate models 2) be supported by the most generalize-able empirical evidence and 3) be the most attractive theory to empiricists. Although the TPB establishes itself as the best foundational theory for an empiricist to start from, it's clear that a more comprehensive model is needed to achieve consistent results and improve our understanding of GPB. NAT and the Theory of Interpersonal Behavior (TIB) offer pathways to extend the TPB. The TIB seems particularly apt for this endeavor, while VBN does not appear to have much to offer. Overall, the TPB has already proven to hold a relatively high predictive value. But with the state of ecosystem services continuing to decline on a global scale, it's important for models of GPB to become more accurate and reliable. Better models have the capacity to help marketing professionals, product developers, and policy makers develop strategies for encouraging consumers to buy green products. / Dissertation/Thesis / M.S.
