The Role of Social Capital in Community-Based Urban Solid Waste Management: Case Studies From Ibadan Metropolis, Nigeria

Wahab, Samuel 18 July 2012 (has links)
Urban solid waste management (USWM) problems facing cities in the developed and developing world are well documented; however, progress in tackling them is very slow in the latter. There are still many communities, neighbourhoods, and local markets where garbage is not collected for a considerable length of time. Many of the affected houses are situated in poor neighbourhoods on the edges and core areas of cities. In order to secure the future of urban environments in the developing world from continuous or perpetual decay, it is important to study the role of social capital in urban solid waste management. Toward this end, a case study research was carried out in Ibadan, Nigeria. For the purpose of the study, social capital was defined as the attributes of social organization, such as trust, cultural norms and social networks by which communities facilitate action. Emerging research suggests that social capital might have an important role to play in effective community-based urban solid waste management initiatives. Empirical evidence suggests that communities with a high level of social capital are in better shape to organize a community-based urban solid waste management project, if the other factors remain supportive. This dissertation seeks to place the concept of social capital in the practice of urban solid waste management, especially at the community level as well as on a wider philosophical and policy levels. The intention here is to advance the understanding of social capital both in relation to its nature as a quality of community life and in terms of its significance as an instrument in the hands of the agents of change. Therefore, this research examines the degree to which social capital and community-based organizations are important in the overall functioning of urban solid waste management at the community level in Ibadan, Nigeria. The main objective of the research was to explore the role of social capital in community-based urban solid waste management and to understand why people participate in voluntary associations for the provision of common goods in Ibadan, Nigeria. This objective is pursued in three specific dimensions: (i) to understand and document the feature of the current solid waste management system in Ibadan; (ii) to explore the extent to which social capital affects community-based urban solid waste management success; (iii) to identify other elements that could facilitate successful urban solid waste management at the community and institutional levels. This study adopts both quantitative and qualitative approaches using multiple data gathering techniques (e.g.) semi-structured face-to-face interviews, direct field observation, focus group, and information sections; conversations with community leaders, key informants, government officials and waste generators to gather different but relevant information and data. The secondary data includes data on waste management from Oyo State Solid Waste Management Authority (OSSWMA) and valuation data from the office of Sustainable Ibadan Project (SIP). The quantitative section of the research encompasses 66 core questions on Social Capital via Integrated Questionnaire. The structured questionnaire measures various elements of social capital using four proxies. The data set covered 7 communities and 385 households and the basic unit of analysis was the neighbourhood. Major findings from the study include: (i) No evidence suggesting that homogeneity is a virtue for collective action in urban solid waste management at the community level nor is there evidence suggesting that homogeneity increases civic engagement in the communities studied. (ii) Empirical evidence suggests that to a great extent, social capital can influence the success of community-based urban solid waste management initiatives. However, social networks among private and professional associations, the density and diversity of social network differ within and between communities. (iii) Empirical field observation results show that social capital had positive influence on the success of community-based urban solid waste management in Bodija, Ayeye, and communities. (iv)The study results indicate that the residents of Agbowo, NTC Road, Foko, and Sasa communities failed to establish community-based USWM initiatives for a range of reasons. Some of the reasons include the paucity of face-to-face interactions among households; resident’s cultural and behavioural differences, lack of charismatic leadership and lack of cooperation among community members. (v) The study results and direct field observations also suggest that there is high-level of social capital among individuals involved in urban solid waste management at the community level in the city of Ibadan. (vi) Field information/observations from Ayeye, Bodija, and Alesinloye communities reveal that social networks and interpersonal relationships were constructed along the line of local identity among the residents. (vii) Empirical findings suggest that the presence of a network of ties based on acquaintances, business partnerships, religious groups, and people from the same region, living in the same community, serve as a foundation for building social relations. The study concluded that Putnam’s generalization and conceptualization of social capital is not completely or equally applicable to different social and political environments. Therefore, it needs to be contextualized according to local problems in order to obtain the gains. The research also reveals that social capital alone is not enough to form community-based urban solid waste management projects in Ibadan, Nigeria. It works well with other elements such as collaborative, incremental planning and community capacity building.

Desta forma, o Parque Ambiental Santa Luzia, por meio de sua estrutura pedagógica, fundamentada na abordagem sistêmica, percepção e educação ambiental inclusiva, tornou-se um excelente recurso didático para atividades de educação ambiental. O jardim dos sentidos propicia a sensibilização através da percepção dos sentidos. A infra-estrutura de esporte e lazer tornou-se um ponto de referência topofílica, principalmente, para os moradores do bairro Santa Luzia e bairros adjacentes. O Centro Sensorial, através da reciclagem artesanal de papel, respeitando a individualidade e habilidade de seus integrantes, tem revelado um meio positivo e um instrumento de grande importância na inserção social das pessoas com deficiência. No sentido mais amplo da educação inclusiva, esta pesquisa permitiu ações concretas de aproximação entre a educação especial e a educação ambiental, iniciando no município de Guaratinguetá, mesmo que ainda de forma incipiente, um olhar para a prática da inclusão das pessoas com deficiência. / The aim of this project was to comprehend the urban solid waste management in Guaratinguetá, considering its economical, social and environmental implications, and to present a proposal for the utilization of the landfill area, after its deactivation and local sanitation. In this way, Santa Luzia Environmental Park, through its pedagogical structure, based on a systemic approach, on an environmental point of view and on an inclusive environmental education, has become an excellent didactic resource for activities of environmental education. The Sensorial Center, through the craftsmanship paper recycle, by respecting the individuality and ability of its members has pointed to a positive way and a very important instrument to achieve the social inclusion of handicapped people. In a broader approach of inclusive education, this research made it possible to have an approximation between special education and environmental education. Although still in an incipient way, this research has helped the town of Guaratinguetá to pay more attention to the social inclusion of handicapped people.

Coleta seletiva e minimização de resíduos sólidos urbanos: uma abordagem integradora / Selective collection and minimization of urban solid waste: an integrative approach

Maria Lucia Barciotte 17 November 1994 (has links)
Este trabalho estudou alguns programas e atividades de coleta seletiva de materiais recicláveis presentes nos resíduos sólidos urbanos. Foram selecionados quatro programas municipais oficiais (São Sebastião, São José dos campos, Santos e São Paulo) e dois trabalhos de organização espontânea (Favela Monte Azul e COOPAMARE/Cooperativa dos Catadores de Papel, Aparas e Materiais Recicláveis de São Paulo). Levantaram-se as formas de implantação das diferentes experiências em estudo e de mobilização das suas respectivas comunidades. Constatou-se que, apesar das variações encontradas nos diferentes casos, o envolvimento das comunidades foi significativo, fornecendo excelente oportunidade de percepção do espaço urbano e do exercício da cidadania, assim como da prática da máxima ambiental ista \"Pense globalmente, aja localmente\". Constatou-se ainda, que, pela complexidade do tema, é fundamental garantir a todas as pessoas envolvidas e interessadas o acesso às informações técnicas claras e precisas, assim como às práticas que motivem a participação de todos e ressaltem a importância do trabalho conjunto. Concluiu-se que, apesar do bom resultado dessas iniciativas, devem ser buscadas e enfatizadas ações que promovam maior integração entre os vários segmentos da sociedade (catadores, populacão, empresários, políticos, artistas, meios de comunicação, instituicões de ensino, entidades religiosas, etc). Deve-se priorizar práticas realmente integradoras e holísticas, capazes de promover a real prevenção da poluição, através da minimizacão de resíduos, isto é, de sua diminuição, a partir da reducão na fonte, reutilização e reciclagem. / This work consisted of a study of activities and programs of selective collection of recycled materials from urban solid waste. The study is based on four official municipal programs (São Sebastião, São José dos Campos, Santos and São Paulo) and two programs of spontaneous organization (Favela Monte Azul and COOPAMARE). This work analyzed the ways of implementation of the referred different experiences and the mobilization of their respective communities. It was verified that despite the observed variation in the different cases, the involvement of the communities was significant, providing an excellent opportunity of perception of the urban space and the practice of citizenship, as well as the environmentalist maximm \"Think globally, act locally\". It was also verified that due to the complexity of the subject, it is essential to ensure that all the people involved and interested have access to clear and precise technical information as well as to practices that stimulate participation and enhance the importance of collective work. It was concluded that despite the good results of the referred initiatives, one must pursue and emphasize actions which encourage integration among different members of society (population, business people, politicians, artists, media, educational institutions, religious groups, etc). One must also emphasize holistic and integrated practices, in order to promote a real pevention of pollution, with waste minimization through reduction in the sources, reuse and recycling.

A taxa de coleta de resíduos sólidos domiciliares: uma análise crítica / The domiciliary solid waste collection tax: a critical analysis

Marcelo Fonseca Leite 22 March 2006 (has links)
Os serviços de coleta e destinação final dos resíduos sólidos urbanos - RSU, são de responsabilidade dos municípios. As despesas decorrentes dos serviços são repassadas na forma de taxas, geralmente lançadas junto com o IPTU. O objetivo desta cobrança é o de recuperar os recursos despendidos neste serviço. O trabalho proposto busca apresentar algumas formas de definição da cota que cada município adota para definir o valor a ser cobrado de cada domicílio no Brasil e alguns casos do exterior, bem como fazer uma análise sobre as possíveis falhas de alguns processos mais utilizados. Outro objetivo é o de realizar levantamento de dados junto a domicílios, no município de Taiaçu-SP, de informações (peso de lixo por residência, consumo de energia elétrica, consumo de água), que possam mostrar possíveis relações entre o volume de lixo gerado e os consumos ligados à residência (água, energia elétrica, etc). Diante dos resultados obtidos, foi proposto um método que permitiu distribuir de forma proporcional a cada residência, o valor da taxa de coleta e destinação final dos resíduos sólidos domiciliares gerados / The urban solid waste - USW collection and final destination services, are the municipal responsibility. The expenses originated from the services are passed again in form of taxes, generally launched with the IPTU. The aim of this exaction is to restore the resource spent in this service. The proposed paper seeks to show some ways of the quota definition that every municipal district adopts to define the value to be charged of each home in Brazil and some cases abroad, as well as to do an analysis about possible faults of some most used process. Another objective is to come true the data survey with the residences in the municipal district of Taiaçu - SP, of information (trash weight per residence, the electrical energy consumption, water consumption), that can show possible relation between the generated trash volume and the consumptions linked to the residence (water, electric energy, etc). Before the acquired results, was proposed a method that allows a proportional way to distribute in each home, a collection tax value and final destination of generated solid waste

Orientador: Marcus Cesar Avezum Alves de Castro / Resumo: Soluções relacionadas a melhores práticas de manejo de resíduos são procuradas por gestores de cidades em todo o mundo. O presente estudo propôs cenários de ação para a gestão dos resíduos sólidos urbanos dos seis municípios com sede na bacia do rio Corumbataí. O estudo foi realizado em duas etapas, a primeira consistiu na elaboração do diagnóstico dos mecanismos praticados atualmente, realizado a partir da análise de um conjunto de indicadores. A segunda etapa foi a composição de cenários para destinação para o tratamento de resíduos orgânicos e disposição final em aterro sanitário dos resíduos sólidos urbanos dos municípios investigados. Foram estudados seis municípios, os quais cinco possuem menos de 30.000 habitantes (Analândia, Charqueada, Corumbataí, Ipeúna e Santa Gertrudes) e Rio Claro possui 199.000 habitantes. Durante a primeira etapa, foram levantados dados e elaboradas matrizes SWOT para cada um dos municípios, com isso, buscou-se apontar fatores positivos e negativos das práticas atuais de gestão. Esses resultados sinalizaram que (i) os municípios ainda não participam de gestão compartilhada para manejo de resíduos; (ii) existe pouco ou nenhum tratamento para os resíduos orgânicos e de poda e capina; (iii) existe coleta seletiva em toda a zona urbana de todos os municípios investigados (iv) existe participação organizada do setor informal na coleta de recicláveis (v) existe possibilidade de gestão compartilhada dos resíduos; (vi) os municípios não possuem sustent...

This study proposed action scenarios for the urban solid waste management of six municipalities located in the Corumbataí River basin. The study was conducted in two stages, the first consisted in the diagnosis of the mechanisms currently practiced, through the analysis of a set of performance indicators. The second stage comprised the composition of operating scenarios for the shared urban solid waste management of the investigated municipalities. Six municipalities were studied, five of which have less than 30,000 inhabitants (Analândia, Charqueada, Corumbataí, Ipeúna and Santa Gertrudes) and Rio Claro has 199,000 inhabitants. During the first part, data were collected and SWOT matrices were elaborated for each of the municipalities studied. Thus, it was sought to point out positive and negative factors of current management practices. These results signaled that (i) municipalities do not yet participate in any consortium for shared waste management; (ii) there is little or no treatment for organic residues; (iii) there is selective collection throughout the urban area of all municipalities (iv) there is organized participation of the informal sector in the collection of recyclables (v) there is the possibility of cities consortium for shared waste management; (vi) municipalities do not have financial sustainability for the waste management system.

Dentre os vários problemas que as cidades enfrentam, a questão dos resíduos sólidos urbanos ganha destaque, seja devido ao aumento exagerado do consumo e, conseqüentemente do lixo, do desenvolvimento de novos materiais, cujo tempo de degradação no ambiente é maior, ou da falta de espaço para depositar todos os rejeitos gerados. Para equacionar esses problemas, o planejamento é uma peça fundamental. Porém, planejamentos autoritários e tecnicistas que não envolvam os outros atores do espaço urbano, ou seja, a sociedade civil organizada e o poder privado, pouco ou nada contribuirão para o desenvolvimento sócio-ambiental e economicamente sustentável. Assim, esta dissertação destaca as possíveis vantagens do envolvimento da sociedade civil organizada no planejamento e gestão urbana, considerando, também, a importância do poder público e do poder privado neste processo. Portanto, evidenciamos o planejamento e gestão participativos e compartilhados como uma forma eficiente de gerir o espaço urbano. / The environmental urban problems have been worsening seriously and steadily since the middle of the twentieth and beginning of the twenty-firth centuries. Among the various difficulties that cities now have to face, the problem of the urban solid refuse stands out, due to either the sharp rise in consumption, and consequently the waste, the development of new materials whose degradation time is longer or the lack of space to deposit the produces waste. To equate these problems, planning is an essential piece. However, authoritarian and technicality planning that does not involve the other actors of urban space, which are the organized civil society and the private sector, will be of little or no contribution towards a socioenvironmental and economically sustainable development. Consequently, this dissertation highlights the possible advantages for the planning of the involvement of the organized civil society, the urban management as well as the importance of the public and private sectors in this process. As result, we witness the planning and the participative and shared management as an efficient way of administrating the urban space.
