“…A contaminação da água subterrânea pela destinação inadequada dos resíduos sólidos pode não ser percebida direta e facilmente pelos moradores, mas poderá trazer graves transtornos, incluindo o adoecimento da população. Assim, se faz necessário construir um ambiente para sensibilizar a população por meio de uma educação contextualizada para a sustentabilidade (Aguiar et al, 2018;Han et al, 2018b).…”

“…A população rural pode incorporar novos hábitos, tanto no sentido de ampliar a consciência ambiental, como de práticas sustentáveis, que impactarão positivamente no bem-estar local (Ceretta, 2013;Wang et al, 2018). O aumento da conscientização e conhecimento ambiental das famílias é uma das principais formas de garantir que as estratégias sejam eficazes, para o desenvolvimento de novas políticas públicas e melhoria da gestão dos resíduos sólidos domiciliares em áreas rurais (Han et al, 2018b). Neste sentido, o modelo de gestão de resíduos sólidos proposto neste estudo está de acordo com as estratégias apresentadas por Dhokhikah et al (2015), para apoiar a participação da comunidade na destinação correta de resíduos sólidos.…”

“…O cenário de poluição ambiental causado pelo manejo inadequado de resíduos está se tornando cada vez mais comum nas áreas rurais de países em desenvolvimento. Como demonstrado, a gestão de resíduos domésticos ainda é ineficiente nessas áreas rurais, onde a falta de investimento adequado em políticas públicas limita apoios financeiros em infraestrutura e logística (Han et al, 2018b). Como consequência dos problemas causados pela disposição inadequada dos resíduos sólidos, famílias rurais esperam esforços governamentais e têm uma forte intenção de apoiar planos de gestão de resíduos em suas comunidades, o que poderia ser aproveitado para ampliar a conscientização destas famílias (Zeng et al, 2016).…”

Os resíduos sólidos rurais representam um grande entrave ao desenvolvimento sustentável pautado na sustentabilidade ambiental, social e econômica. A destinação incorreta dos resíduos sólidos promove impactos negativos à saúde humana e aos sistemas ambientais. Portanto, os objetivos desta pesquisa foram descrever a forma de disposição final dos resíduos sólidos domiciliares em sete comunidades rurais inseridas na Zona de Amortecimento do Parque Nacional da Furna Feia, RN, e apresentar uma proposta de gestão adequada de resíduos sólidos produzidos nestas comunidades. A metodologia foi pautada na observação não participante, com base na lógica de investigação fenomenológica, e na pesquisa-ação, visando contribuir com a gestão dos resíduos sólidos domiciliares. Para a espacialização dos elementos de logística e infraestrutura do modelo de gestão proposto neste estudo, que inclui rotas e pontos de coleta de materiais recicláveis, utilizou-se um sistema de informação geográfica, o Quantum GIS, com o auxílio do módulo de digitalização. Os dados indicaram que em todas as residências avaliadas ocorre a queima de resíduo sólido, enquanto a reutilização de materiais recicláveis foi registrada em 57,5% das residências. O resíduo orgânico, compreendido por sobras de alimento, foi destinado à alimentação de animais domésticos e de produção. Com base nestes dados, é apresentada uma proposta de gestão adequada dos resíduos sólidos domiciliares, com foco na reutilização de materiais recicláveis, com possibilidade de geração de renda, por meio de cooperativas e/ou associações. Para os rejeitos, elaborou-se uma proposta de coleta intermunicipal, visando diminuir gastos operacionais e possibilitar a sustentabilidade socioambiental. Proposed Appropriate Management of Household Solid Waste in Rural Communities Using Spatial Analysis A B S T R A C TRural solid waste represents a major obstacle to sustainable development based on environmental, social and economic sustainability. Incorrect disposal of solid waste causes negative impacts on human health and environmental systems. Therefore, the objectives of this study were to describe the form of final disposal of household solid waste in seven rural communities inserted in the buffer zone of Furna Feia National Park, RN, Brazil, and present a proposal for appropriate management of solid waste produced in these communities. The methodology was based on non-participant observation, through of the logic of phenomenological research, and action research, aiming to contribute to the management of household solid waste. For the spatialization of the logistics and infrastructure elements of the management model proposed in this study, which includes routes and collection points for recyclable materials, we used a geographic information system, Quantum GIS, with the aid of the digitization module. Data indicated that in all households evaluated, solid waste is burned, while the reuse of recyclable materials was recorded in 57.5% of households. The organic waste, comprised of food scraps, was destined to feed domestic and farm animals. Based on these data, we present a proposal for the appropriate management of household solid waste, focusing on the reuse of recyclable materials, with the possibility of generating financial resources through cooperatives and/or associations. For the tailing, we elaborated a proposal for intercity collection, aiming to reduce operating expenses and enable social and environmental sustainability.Keywords: Geoprocessing; Environmental management; Public policy; Sustainability; Protected area.

“…The quantity of waste generated in the urban is increasing with population. Han et al (2018) reported a positive linear relationship between waste generation amount and population size (R 2 = 0.9405). Most of the MSW composting studies in the tropics have concentrated on physicochemical properties of the process and product but there is relatively little knowledge available on microbial characteristics.…”

Bacterial communities are actively involved in composting process but the environment within the compost influences their diversity, abundance and succession. In this study, the authors investigated the bacterial communities in tropical crop waste compost using pyrosequencing. Municipal crop wastes from the tropics (Uganda) were composted under four different low-technology methods. Samples were collected from the early thermophilic, late thermophilic, and mesophilic phases, and from mature compost. Pyrosequencing of the amplified variable V4 region of the 16s rDNA generated over 110 000 sequences. Chao1 and cluster analysis at 3% dissimilarity showed that bacterial community richness declined during the composting process. The community was dominated by a few bacterial taxa during the thermophilic phases. Species evenness increased as compost progressed to maturity despite a decline in the number of taxa over the successional progression. Bacterial community diversity, abundance and succession changed with the composting method. This pattern of diversity may be attributed to competition and selection during the microbial succession. A total of 22 phyla and 513 genera were identified from all the methods in the entire composting process. The most abundant phyla were Proteobacteria, Firmicutes, Bacteriodes and Actinobacteria. Pyrosequencing provided more information on compost bacterial community diversity and abundance than previously used molecular methods. Several novel bacteria existing in tropical crop waste compost remained unclassified.

The paper examines the waste management issues in the villages annexed to administrative-territorial units of the Romanian cities which have been frequently neglected by urban waste operators. The lack of waste collection services in such periurban communities favored the illegal waste disposal practices particularly prior to EU accession. The extension of waste collection services from main cities to such areas is compulsory in order to mitigate the environmental risks and the public health threats. The paper estimates the amounts of household waste susceptible to be uncontrolled disposed of by peri-urban villages in different geographical areas of North-East region with a particular focus on Neamt county. The paper points out that these rural settlements should receive the same attention concerning the municipal waste management services as the main urban areas. Traditional recovery of waste fractions at the household level (e.g., home composting) should be further promoted in such areas in order to avoid illegal dumping issue and to prevent the landfill of biodegradable waste as requested by EU regulations.
