Environmental Impacts of Tourism in Khao Yai National Park, Thailand

Phumsathan, Sangsan 2010 August 1900 (has links)
Knowledge of visitor impacts is critical for sustainable tourism management in national parks. The focus of past tourism impact research on national parks is either on bio-physical impacts (conducted as recreation ecology research) or on social impacts (human dimensions, including environmental perception and crowding). Research integrating these two dimensions has been rarely conducted. This research aims to fill this gap through the integrative approach that attempts to understand current biophysical impacts of visitor activities in a national park, and it examines how visitors perceive these impacts. The primary objectives of this dissertation are 1) to provide a synthesis of existing of bio-physical impacts of visitor activities in the Khao Yai National Park (KYNP) and 2) to examine visitors’ perception of those impacts. Also, the factors affecting visitors’ perception are analyzed. Both qualitative and quantitative methods were used in this study. Previous impact studies conducted in KYNP were reviewed. A visitor survey was conducted between December 2008 and February 2009. The questionnaires were distributed to 628 domestic and 40 international visitors. The 38 KYNP official interviews were completed. Based on previous impact research in KYNP, the most common bio-physical impacts include soil compaction, removal of humus layer, erosion, plant damage, soil and root exposure, water quality deterioration, disturbance and feeding wildlife. Other environmental impacts include noise pollution and garbage accumulation. The results indicate that more than 30 percent of visitors do not recognize the negative results of their activities. With the exception of vegetation and water impacts, overall, visitors perceive the impacts as less severe than the actual impacts. Environmental impacts are rated differently by the KYNP officials, domestic, and international visitors. Also, significant differences were found among birders, hikers, and campers. The key factors influencing impact perceptions include income level, education level, residential location, park visitation experience, length of stay in KYNP, recreation activity, frequency of activity, group type, and group size. It is suggested that both the quality and the quantity of visitor impact research are needed to construct the body of knowledge of impacts in KYNP. A long-term impact monitoring is required to sustain the ecological integrity in KYNP.

Biosocial reciprocity in environmental communication: a study of giant panda conservation communication in China

Yang, Liuqing 25 April 2007 (has links)
This study proposes biosocial reciprocity framework in environmental communication, which suggests the interdependent relationships between mass media, people's attitudes, and the physical environment. Biosocial reciprocity is applied to analyze the mass media's possible roles in giant panda conservation in China. The mass media's image construction of giant pandas is assessed through a content analysis of People's Daily (1995 to 2004); the conservation awareness, activities, and environment changes are assessed by a review of the country's giant panda conservation history and policies. The result suggests active interrelations among the media, Chinese attitudes toward wildlife, and the loss of wild panda population and habitat. The study urges that to positively influence the natural world, much needs to be done to improve the Chinese media's effectiveness in fostering grassroots environmental value and awareness. Biosocial reciprocity provides a practical conceptual framework for this study to sort out media-related linkages between the social and physical world of giant panda conservation.

Hållbarhetsanpassade Lean-metoder på tillverkande företag : Redogörelse av Green Lean-metoder och hur de bör appliceras / Sustainability-adapted Lean methods in manufacturing companies : Explanation of Green Lean methods and how they should be applied

Kilander, Hugo, Jakobsson, Aston January 2023 (has links)
I dagens samhälle finns ett stort behov av processeffektiviserings-metoder för att hålla företaget konkurrenskraftigt gällande produktivitet och effektivitet. Samtidigt satsar företag idag mycket på ekologisk hållbarhet, vilket har öppnat dörren för nya så kallade Green Lean-metoder vars syfte är att förbättra både produktivitet och hållbarhet. I detta arbete behandlas metoderna 5S, Environmental Value Stream Mapping, Green Lean Six Sigma samt Green Kaizen. Syftet med arbetet var att redogöra för innebörden av respektive metod samt motivera hur dessa metoder bör appliceras och implementeras i praktiken. Först behandlades metoderna teoretiskt, därefter praktiskt med enkäter. I arbetet behandlar vi företaget Scania och undersöker hur de valt att applicera och använda de metoder, hållbara metoder, de idag använder. Resultatet visade att det finns flera olika drivkrafter till varför man väljer att implementera Green Lean-metoder samt flera olika aspekter som påverkar vilka metoder som bör väljas, som exempelvis kundkrav eller erfarenhet och kunskap inom företaget. Scania använder idag Green Performance Map och Energy Kaizen som Green Lean-metoder. Slutsatsen som drogs är att metoden som bör implementeras varierar beroende på vad företaget tillverkar, hur långt de kommit med andra processeffektiviserings-metoder såsom Lean Production och Six Sigma. Om det är en problemdriven lösning så är EVSM en stark metod medan 5S bör implementeras uppifrån ledningen. / In today's society, there is a significant need for process improvement methods to maintain a company's competitiveness regarding productivity and reasonable pricing. Additionally, companies are investing heavily in environmental sustainability, leading to the emergence of new "Green Lean" methods aimed at creating improvements in both productivity and sustainability. This study examines the methods of 5S, Environmental Value Stream Mapping, Green Lean Six Sigma, and Green Kaizen. The aim of the study is to explain the meaning of each method and to motivate how these methods should be applied and implemented in practice. The methods were first studied theoretically and then practically with surveys. Scania was chosen as a case study to examine how they have chosen to apply and use the methods they have. The results showed that there are several driving forces for why companies choose to implement Green Lean methods, and several aspects affect which methods should be chosen, such as customer requirements or experience and knowledge within the company. Scania currently uses Green Performance Map and Energy Kaizen as Green Lean methods. The conclusion drawn is that the method to be implemented varies depending on what the company produces, and how far they have progressed with other process improvement methods such as Lean Production and Six Sigma. If it is a problem-driven solution, EVSM is a robust method, while 5S should be implemented by top management.

Miljövärdeflödesanalys av Risifruttiproduktionen : En utvärdering av värdeflödesanalys och miljövärdeflödesanalys

Oweini, Sana January 2012 (has links)
This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines. / Denna rapport är resultatet av ett examensarbete utfört på Risifruttiproduktionen hos företaget Procordia Food AB. Examensarbetet är på D-nivå och är det slutgiltiga arbetet för att författaren ska få en Civilingenjörsexamen inom Innovativ produktion vid Mälardalens Högskola. Examensarbetet omfattar 30 högskolepoäng och har pågått i 18 veckor.   Examensarbetet är i huvudsak en forskning av huruvida det är möjligt att utföra en Miljövärdeflödesanalys på en livsmedelsprocessindustri samt en utvärdering av om Miljövärdeflödesanalys och Green Performance Map verktygen är användbara i denna typ av industri. En bidel till denna forskning är att med hjälp av resultaten från Miljövärdeflödesanalysen ge Procordia Food AB information om vad som bör förbättras i Risifruttiproduktionen.   Författaren har haft det svårt att samla in vissa kvantitativa data till Miljövärdeflödesanalysen, främst beträffande energiåtgång i delprocesserna, men har ändå med hjälp av en Värdeflödesanalys och andra Lean verktyg kunnat identifiera och kvantifiera flera slöserier i Risifruttiproduktionen. Rekommendationer till förbättringar baserade på dessa slöserier har givits till företaget.   I forskningsanalysen har verktygen Värdeflödesanalys, Miljövärdeflödesanalys samt Green Performance Map användbarhet i en livsmedelsprocessindustri analyserats. Författaren har funnit att Värdeflödesanalys är ett användbart verktyg då slöserier och ojämnheter i produktionstakt har kunnat identifieras. Miljövärdeflödesanalys och Green Performance Map verktygen är också bra verktyg när ett företag vill analysera sin miljöbelastning för att sedan investera i miljöförbättringar. Dock har inga djupare energianalyser kunnat göras i Risifruttiproduktionen eftersom energimätare för el, ånga och tryckluft saknades i produktionen.

A Case for Decision-Maker Obligation Based Justification of Environmental Policy

Robertson, Jamie Kathleen 14 October 2011 (has links)
The environment is seen by different people as being valuable for different reasons. A pervasive debate in Environmental Philosophy revolves around which values should hold sway in the case of conflicts between the various kinds of value associated with the environment. This debate is relevant to, and fuelled by, debates how human communities should make decisions about the environment. By exploring the methods for balancing the various forms of environmental value proposed by Bryan G. Norton, Mark Sagoff, and David Pearce, I will argue that, as of yet, there has been little progress towards constructing a morally satisfactory basis for giving particular environmental values more weight than others. I will argue that to the extent that decision-maker obligations constitute moral obligations to the community, they can act as a basis for justifying giving some environmental values precedence over others in the decision-making context.

Assimilação do valor meio ambiente pela sociedade brasileira / Assimiliation of environmental value by the brazilian society

Ferreira Neto, Themístocles Barbosa 27 August 2007 (has links)
A crise ambiental atual vivida pela sociedade, decorrente da conscientização dos prejuízos advindos da contínua depleção de recursos naturais causada por ação antrópica, introduziu o meio ambiente no cenário político e econômico do mundo. Porém, a preocupação com a preservação ambiental ainda não é compartilhada da mesma forma, pelas sociedades integrantes do planeta. No Brasil, a despeito da legislação vigente sobre o tema, grande parte da população ainda não expressa em seu cotidiano, o valor meio ambiente, protegido pela Constituição Federal. A compreensão da dicotomia existente entre o que dispõe a legislação ambiental brasileira e o que a sociedade efetivamente expressa acerca do tema, pode ser feita pela história, marcada pelo extrativismo e pelos equívocos decorrentes da idéia de infinitude dos recursos naturais, que permeia desde o período colonial. As questões ambientais estão diretamente ligadas aos interesses de toda a coletividade. Não podem ser analisadas sob o predomínio de individualidades. A correta utilização dos princípios ambientais constitucionais e dos instrumentos de política ambiental, como o zoneamento e a avaliação de impacto ambiental (AIA), ambos previstos na lei de política nacional do meio ambiente (Lei no. 6.938/81), pode auxiliar a difusão e assimilação pela sociedade, do valor meio ambiente, protegido pelo ordenamento jurídico brasileiro, na medida em que sua aplicação, pode minimizar prejuízos econômicos decorrentes de impactos ambientais, como ilustra o processo de registro do loteamento Cidade Aracy, na cidade de São Carlos, SP, Brasil. / Nowadays, the environmental crisis, experienced by society, resulting from awareness of damages that come from continuous depletion of natural resources caused by human actions, has introduced the environment in the world\'s political and economic scenery. Nevertheless, concerns about environmental preservation are not shared in the same way by all the global societies. In spite of current legislation in Brazil, a great part of the population does not, ordinarily, express the environment value protected by the Constitution. The comprehension of the dichotomy between what the brazilian environmental law dictates and what society effectively expresses about the theme, may be understood by a history, marked by extractvism and by mistakes derived from the idea of endless natural resources, that has existed since colonialism. Environmental issues are directly linked to the interests of the entire community. They can not be analyzed exclusively by the predominance of individualities. The correct use of constitutional environmental principles, and also of environmental policy procedures, such as the environmental impact assessment and the environmental zoning, may help the diffusion, as well as the assimilation by society of the environmental value protected by law, as far as its applicability may minimize economic damages resulting from environmental impacts as illustrated by the process of land division registration in an area named Cidade Aracy, located in São Carlos, Brazil.

CERTIFICAÇÕES E INDICADORES SOCIOAMBIENTAIS: RELAÇÃO, DISCURSO E VALOR DA MATERIALIZAÇÃO ESPACIAL.

Ricchetti, Patrícia 20 October 2010 (has links)
This paper presents a comparative analysis of hierarchical variables indicators of socioenvironmental certification from the scene. The indicators take values handled in the business to the environment. For such understanding, we begin with assumptions that each society conceives the nature of the built environment and social relations. From this perspective, it is understood that the relationship that societies construct themselves and together with the building with the building with nature, materialize in space. Hence, when we speak of production space we are considering that this is the product of the inseparability of social and natural, like a hybrid of historical processes that have developed as forms of social organization and uses of nature. Since the construction of the environmental scene take the concept of public sphere as a locus of realization spaces of argument, which echoes and integrates the policy as a whole interrelated. In both speeches that no originals of the formal resolutions (that support micro) as institutionalized make incursions into the public sphere, moving public opinion and pressure various sectors such as government and civil organizations, intent on (re) introduce the man as the subject of actions in the political scene, and environmental discourse. The methodology was qualitative, based on analysis of questionnaires between the groups: researchers associated with the National Association of Graduate Studies and Research in Environment and Society-ANPPAS, professionals working in environmental, nongovernmental organizations related to environmental issues , state environmental agencies, state sanitation companies (respondents to the questionnaire 1) and state sanitation company certified by ISO 14001 (questionnaire respondent 2). What was found was that the indicators incorporate social and environmental variables in a psychosphere originating in non-institutionalized social spheres. These variables are operationalized in the strategies and actions to generate competitive advantage, market access, and to generate confidence among the various stakeholders. Where the certificates are presented as network variables tailoring sectors, constitute and embody the company's relations with its parts. / Este trabalho apresenta a análise comparativa hierarquizada de variáveis dos indicadores das certificações da cena socioambiental. Os indicadores são tomados como valores agenciados na relação empresa- meio ambiente. Para tal entendimento, partimos de pressupostos que cada sociedade concebe natureza o ambiente construído pelas e para as relações sociais. Nessa perspectiva, compreende-se que a relação que as sociedades constroem em si e, juntamente, com a que constroem com a natureza, materializam-se no espaço. Daí que, ao falarmos de produção de espaço estamos considerando que esse é produto da indissociabilidade do social e do natural, como um híbrido de processos históricos que se desenvolveram como formas de organização social e dos usos da natureza. Sendo que na construção da cena ambiental tomamos o conceito de esfera pública como lócus de realização dos espaços de argumentação, que repercute e integra a política como um todo interrelacionada. Em que tanto os discursos não originais dos espaços formais de deliberação (que dão suporte à micropolítica) como os institucionalizados fazem incursões pela esfera pública, movimentando a opinião pública e pressionando diversos setores tais como governo, organizações e civis, na intenção de (re)introduzir o homem como sujeito das ações na cena política-discursivaambiental. A metodologia aplicada foi qualitativa, baseada em análise de questionários aplicados entre os grupos: pesquisadores associados à Associação Nacional de Pós-Graduação e Pesquisa em Ambiente e Sociedade- ANPPAS, profissionais liberais que trabalham na área ambiental, organizações não-governamentais ligadas à temática ambiental, órgãos ambientais estatais, empresas estaduais de saneamento (respondentes do questionário 1) e empresa estadual de saneamento certificada pela ISO 14001 ( respondente do questionário 2). O que se constatou foi que os indicadores incorporam as variáveis socioambientais de uma psicosfera originária de esferas sociais não institucionalizadas. Estas variáveis são operacionalizadas nas estratégias e ações para geração de vantagem competitiva, acesso a mercados, e para a geração de confiança entre os diversos públicos de interesse. Em que as certificações se apresentam como uma rede de variáveis que costuram setores, constituem e materializam as relações da empresa com suas partes.

O Ribeirão das Pedras drena águas do Distrito de Barão Geraldo e dos Bairros Santa Genebra, Jardim Costa e Silva, Alto Taquaral, Jardim Primavera e outros. Nesta bacia se localizam os campi de diversas instituições de ensino e pesquisa como a Universidade Estadual de Campinas (Unicamp) e a Pontifícia Universidade Católica de Campinas, além de diversas indústrias e estabelecimentos comerciais de grande porte. Na área da bacia, 29,7 km2, residem cerca de 36 mil habitantes, totalizando mais de 1200 hab/km2. O mapa final, elaborado com base na representação proposta por Journaux (1985), utilizou dados adquiridos em trabalhos de campo, além de outros resultados do Projeto Anhumas ¿ FAPESP. Dentre o total de 120 situações de riscos mapeadas, os maiores, em área, foram identificados como riscos relacionados ao cultivo agrícola, com a utilização de agrotóxicos e o cultivo de Organismos Geneticamente Modificados (OGM), além das situações de riscos especiais, relacionados à presença da Unicamp e do Shopping Parque D. Pedro como as principais fontes de riscos da Bacia. Ao final, são feitas sugestões de continuidade para o estudo de riscos ambientais utilizando o mapeamento participativo de riscos e a proposta de cartografia elaborada com base em Journaux (1985) / Abstract: This work deals with the environmental risks at Ribeirão das Pedras, an important subwatershed of the Ribeirão das Anhumas watershed, at Campinas, São Paulo state. The Ribeirão das Pedras drains waters of the of Barão Geraldo district and the quarters called Santa Genebra, Jardim Costa e Silva, Alto Taquaral, Jardim Primavera and other quarters. In this basin is located universities, as the State University of Campinas (Unicamp) and the Pontifical University Catholic of Campinas, and big industries and commercial establishments. In this watershed live 36 thousand inhabitants, in one area like 29,7 km2, totalizing more than 1200 hab/km2. The final map, elaborated on the basis of the representation proposal for Journaux (1985), used data collected in fieldwork, and additional results of the Anhumas Project - FAPESP. Amongst the total of 120 mapped risk situations, the biggest, in area, was identified a risks related to plantation with agro-toxics and the culture of genetically modified organism (GMO). Moreover, the presence of the Unicamp and Dom Pedro Shopping, classified as special situation of risk, are related as the main sources of risks of the watershed. At the end, suggestions are made for the continuity of using the participatory risk mapping and the cartography elaborated on the basis of Journaux (1985) in other environmental risk studies / Mestrado / Análise Ambiental e Dinâmica Territorial / Mestre em Geografia
