| ABSTRACT Sanitation (which includes national public policies for drinking water, sewage services and waste management) is precarious in Brazil and therefore poses a challenge to a range of actors. Poor sanitation impacts public health, education, the environment, and daily life. Globally, it emits increasing greenhouse gases. Universalization of any major public service appears difficult, if not impossible; however, Brazil’s program to universalize access to electricity proves the opposite, as will be shown in this paper. By describing the successful implementation of electricity for everyone, we show that planned public efforts, coordinated with private initiatives and local communities, have worked, and the same can be achieved for the sanitation... |

| The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to... |

| Abstract Based on the need to monitor air pollution and on the importance of doing it with biological organisms, the present work had as main objective to assess air quality in urban areas through lichen transplants. Besides, we also tested whether there were differences among the studied sites, aiming to point out the main pollution characteristics of the areas. The monitoring was carried out in seven cities, which varied from mainly rural to mainly industrial, in Rio Grande do Sul, southern Brazil. The foliose lichen Parmotrema tinctorum was used as the biomonitor species. Physiological tests and contents of sulphur and heavy metals were measured in the lichen thalli. Other pollutants assessed through air samplers were available for some cities, and... |

| This dissertation presents the results of statistical analyses of large climate datasets from two time intervals – the 20th century instrumental record and the proxy record of the last deglaciation – in order to understand the forcings and mechanisms of past climate variability. A longstanding question in climate dynamics concerns the origin of Pacific decadal variability (PDV). This issue is addressed by calculating the Southern Hemisphere equivalent of the Pacific Decadal Oscillation (PDO) index from Pacific sea surface temperature (SST) anomalies over the 20th century, which is found to be similar to its Northern Hemisphere counterpart. The Northern and Southern PDO indices both exhibit pronounced seasonality in autocorrelation with interannual... |

| O presente trabalho trata da relevância de ações de enfrentamento das condicionantes ambientais ligadas à pecuária brasileira, como forma de alavancar seu crescimento com o mínimo de danos ao meio ambiente. O indicador ambiental Pegada Ecológica (PE) expressa a pressão do consumo humano sobre o meio ambiente, no Brasil e no mundo. A partir de dados internacionais da Global Footprints Network procedeu-se ao agrupamento de países segundo a participação de cada um dos principais componentes que integram a PE. Cinco grupos foram encontrados, estando o Brasil enquadrado naquele que se caracteriza pela predominância de uma bovinocultura extensiva em pastagens e, relativamente, baixo consumo de energia fóssil (grupo 3). No caso brasileiro, o componente... |

| Biochar (carbonized biomass for agricultural use) has been used worldwide as soil amendment and is a technology of particular interest for Brazil, since its ?inspiration? is from the historical Terra Preta de Índios (Amazon Dark Earth), and also because Brazil is the world?s largest charcoal producer, generating enormous residue quantities in form of fine charcoal and due to the availability of different residual biomasses, mainly from agroindustry (e.g., sugar-cane bagasse; wood and paper-mill wastes; residues from biofuel industries; sewage sludge etc), that can be used for biochar production, making Brazil a key actor in the international scenario in terms of biochar research and utilization). In the last decade, numerous studies on biochar have been... |

| O biocarvão (biomassa carbonizada para uso agrícola) tem sido usado como condicionador do solo em todo o mundo, e essa tecnologia é de especial interesse para o Brasil, uma vez que tanto a ?inspiração?, que veio das Terras Pretas de Índios da Amazônia, como o fato de o Brasil ser o maior produtor mundial de carvão vegetal, com a geração de importante quantidade de resíduos na forma de finos de carvão e diversas biomassas residuais, principalmente da agroindústria, como bagaço de cana, resíduos das indústrias de madeira, papel e celulose, biocombustíveis, lodo de esgoto etc. Na última década, diversos estudos com biocarvão têm sido realizados e atualmente uma vasta literatura e excelentes revisões estão disponíveis. Objetivou-se aqui não fazer uma revisão... |
