Atliekų tvarkymo politika ir valdymas. Savivaldybės lygmuo / Waste policy and management. Municipal level

Vaitkūnienė, Lina 22 February 2010 (has links)
Atliekų valdymo problema šiandien aktuali daugeliui ES valstybių, įgyvendinančių ES atliekų valdymo politiką. LR dar tik žengia pirmuosius žingsnius, pertvarkydama atliekų valdymo sistemą. Atliekų tvarkymas įstatymuose apibrėžiamas priemonė, bet ne kaip nuoseklus valdymo procesas. Tai sukelia nesusipratimų valdžios struktūrose. Didžiausia atsakomybė tenka savivaldybėms, jos įgyvendina atliekų tvarkymą tiesiogiai, o valdymo klausimus turinčios spręsti valdžios institucijos, dubliuodamos viena kitos veiklą, nepriima radikalių sprendimų, kurie šiandien jau būtini. Tvirtas požiūris į šią problemą ir raginimas kurti atliekų deginimą buvo išsakytas ir pačios prezidentės Dalios Grybauskaitės 2009 m. rugsėjo 2d, Kaune vykusiame susitikime su Kauno miesto savivaldybės vadovais, raginusios greitu metu imtis veiklos, kadangi žinoma, jog LR yra remiama ES, yra ir įsipareigojusi ES. Išanalizuotos direktyvos, įstatymai, planai, ataskaitos įgalina teigti, kad būtinas valdančių struktūrų greitas sprendimų priėmimas ir tikslų įgyvendinimas, apibrėžiant įstatymuose tiksliau institucijų pareigas ir užduotis, imantis sukauptų atliekų gyvavimo ciklo pratęsimo, įvertinant LR valstybės piliečių sąmoningumą atliekų tvarkyme (diegiamos naujovės įsitvirtina negreitai, o atliekos kaupiasi sparčiai). / Waste management problem in today's relevant for many EU countries to comply with EU waste management policy. Republic of Lithuania yet just takes its first steps in restructuring of the waste management system. Waste management legislation is defined as a tool rather than as a management process. This leads to misunderstandings inside power structures. The main responsibility lies with the municipalities, they implement waste management directly, and the authorities having to address governance issues, duplicating each other's activities does not accept radical solutions, which today are essential. Robust approach to this problem and call for the incineration of waste has been expressed by president Dalia Grybauskaite on 2009 September 2nd at a meeting with Kaunas municipality heads, she called in short time to take action, since it is known that RL is supported by the EU, is committed to the EU. Analyzed directives, laws, plans, reports allows to assert that the rapid decision-making and implementation of the objectives is necessary for managing structures, defining duties and tasks of the authorities more precisely, through the extension of the life cycle of the waste generated, taking the RL state citizens' awareness of waste management (innovation far from gaining ground, and waste builds up quickly).

No. of bitstreams: 1 texto completo.pdf: 1766611 bytes, checksum: 1073d8eb94bf6d06b0b739d161296879 (MD5) Previous issue date: 2012-01-20 / Each individual recognizes, reacts and responds differently, depending on the environment. These responses or events are therefore a result of perceptions, cognitive processes, judgments and expectations of each individual. The study of environmental perception is critical to help us better understand the interrelationships between human being and the environment in which we live, our expectations, satisfactions and dissatisfactions, values and behaviors. The result is that there is a better understanding of this relationship and allow human to developed efficient ways to retrieve the methodological gaps and problems arising out of the man versus environment relationship. Aiming to elucidate more about this relationship, we sought to verify the environmental perception of the population of Desterro do Melo, about the importance and impact of municipal solid waste. For this purpose, we conducted field work in the city where residents were asked to answer a structured questionnaire on the subject, the population was divided into municipal, housewives or responsible for home and students, the response obtained from the first group (municipal) was used to build a municipal selective collection program, the response of the second group (students), was used build an alternative methodological program content offered by formal education. The questionnaire was answered by 313 homes and showed important conceptual flaws related to solid disposal management, demonstrating the need for leveling concepts about this subject. At school the questionnaires were submitted to students from 5th to 9th year in elementary school and 1st to 3rd year in high schools, totalizing 356 questionnaires, of this total, 268 corresponded to elementary school students and 88 to high school students. The pattern of responses in all levels of elementary school were similar, allowing to group responses indicating that the relationship between years of study and environmental knowledge is not linear, often high school students had higher lags of the environmental knowledge compared to elementary students, highlighting the gaps in environmental education in formal education which enabled the construction of methodological alternatives that seek the inclusion of environmental content in education / Cada indivíduo percebe, reage e responde diferentemente frente às ações sobre o meio. As respostas ou manifestações são, portanto, resultado das percepções, dos processos cognitivos, julgamentos e expectativas de cada indivíduo. O estudo da percepção ambiental é fundamental para que possamos compreender melhor as inter-relações entre o homem e o ambiente no qual vive, suas expectativas, satisfações e insatisfações, valores e condutas. Fazendo assim com que haja uma melhor compreensão deste relacionamento e permitindo que sejam desenvolvidas formas metodológicas eficientes para recuperar as defasagens e problemas advindos da relação homem X ambiente. Objetivando elucidar mais sobre esse relacionamento, buscou-se verificar a percepção ambiental, da população do município mineiro Desterro do Melo, acerca da importância e impactos dos resíduos sólidos urbanos. Para tal, foi realizado um trabalho de campo onde os moradores do município foram convidados a responder um questionário estruturado sobre à temática, a população foi dividida em municipal, donas de casa ou responsáveis pela residência e estudantil, sendo que a resposta obtida com os primeiros foram utilizadas para a construção do programa de coleta seletiva municipal e a resposta do segundo grupo, os estudantes, foi utilizada para a construção de alternativas metodológicas do conteúdo programático oferecido pelo ensino formal. O questionário foi respondido por 313 residências e demonstrou importantes falhas conceituais relacionadas com a gestão dos resíduos sólidos, demonstrando a necessidade de nivelamento de conceitos sobre este assunto. Na escola os questionários foram aplicados aos alunos do 5º ao 9º ano do ensino fundamental e nas três séries do ensino médio, totalizando 356 questionários, deste total, 268 corresponderam aos estudantes do ensino fundamental e 88 as três séries do ensino médio. O padrão de respostas em todas as séries do ensino fundamental foram semelhantes, possibilitando o agrupamento das respostas indicando assim que a relação entre anos de estudos e conhecimento ambiental não é linear, muitas vezes os alunos do ensino médio apresentaram maiores defasagens do conhecimento ambiental do que os alunos do ensino fundamental, evidenciando as lacunas da formação ambiental no ensino formal o que possibilitou a construção de alternativas metodológicas que buscam a inserção do conteúdo ambiental no ensino.

Vliv plánovaného zařízení KIC Odpady (ZEVO) v Karviné na postoje obyvatel a síla vlivu NIMBY efektu / The influence of planned project KIC Odpady (WtE) in Karviná city on residents' attitude and the strength of NIMBY effect

Ryba, Jakub January 2014 (has links)
Although there is, in general, a significant level of support of projects related to use of renewable resources, in fact realization of the specific projects usually meets with negative attitude of local residents. This negative attitude is often called as NIMBY ("not in my backyard") effect without further research of particular causes. Therefore, in the theoretical part of this diploma thesis NIMBY effect is defined, as well as various attitudes to its interpretation in literature and also the effect of various compensation on changing residents' attitude. In the practical part, this diploma thesis analyses residents' attitude, the existence and strength of NIMBY effect and the effect of compensation on changing residents attitude towards the specific planned project of building WtE in Karviná city (KIC). The results of this analyzation show, that NIMBY effect is detected, but at the same time it is not the main cause of the negative attitude of residents. Moreover, it has been found out, that the offered compensation have not any important influence on the change of residents' attitude.
