| The intensification of agricultural production systems demand power, supplied by agricultural machinery, besides more agricultural inputs such as fertilizer, pesticides and seeds. Agricultural mechanization provided increase in the global production of food, fiber and bioenergy; and it brought economic benefits to producers, but causing larger energy consumption. Energy embodiment in agricultural machinery has been approached, but data usually are from car industry. This study aimed to determine the energy demand in a plant that assembles five types of agricultural machinery from a multinational manufacturer located in Piracicaba municipality in Sao Paulo state, Brazil. That plant assembles two types of sugarcane harvester, coffee harvesters, sprayers and... |

| Today, fish farming faces an increasing demand in fish products, but also various environmental challenges. Genetic improvement in growth rate and feed conversion ratio is known to be an efficient way to increase production and increase efficiency in fish farming. The environmental consequences of genetic improvement in growth rate and feed conversion ratio, however, are unknown. In this study, we investigated the environmental consequences of genetic improvement in growth rate and feed conversion ratio in an African catfish farm, using Recirculating Aquaculture System (RAS). In RAS, total fish production of the farm is limited by rearing density or by the capacity to treat dissolved nitrogen. To evaluate the environmental consequences of genetic... |

| Abstract The objective of this paper is to evaluate, through the 100-year Life Cycle Analysis, Global Warming Potential (GWP) and Global Temperature Increasing Potential (GTP) impact categories. It is proposed scenario of replacement of the energy matrix for the supply of electricity by Solar Photovoltaic, adopting as consumption base the facilities of Supermarkets, as they contribute to environmental impacts for greenhouse gas emissions such as: intensive use of electricity, occupation large areas such as the main building or parking lot sealing the ground, the movement of customers' vehicles with air and noise pollution and the use of plastic bags. Modifying the energy matrix using electricity from renewable sources enables the reduction of greenhouse... |

| Resumo: A Avaliação do Ciclo de Vida (ACV) é uma metodologia sistêmica e iterativa aplicada como técnica para quantificar potenciais impactos ambientais de produtos e serviços. Para isso, esse tipo de avaliação considera todas as entradas e saídas ao longo do ciclo de vida do sistema estudado. É estruturada a partir de quatro fases principais: (i) definição de objetivo e escopo; (ii) análise do inventário do ciclo de vida (ICV); (iii) avaliação de impactos do ciclo de vida (AICV); e (iv) interpretação. É durante o ICV que ocorre a compilação e quantificação das entradas e saídas do sistema a ser estudado. Essa fase envolve, portanto, a coleta dos dados necessários para a avaliação, como insumos (materiais e energia), emissões e resíduos, além da... |

| Biochar has the potential to make a major contribution to the mitigation of climate change, and enhancement of plant production. However, in order for biochar to fulfill this promise, the industry and regulating bodies must take steps to manage potential environmental threats and address negative perceptions. The potential threats to the sustainability of biochar systems, at each stage of the biochar life cycle, were reviewed. We propose that a sustainability framework for biochar could be adapted from existing frameworks developed for bioenergy. Sustainable land use policies, combined with effective regulation of biochar production facilities and incentives for efficient utilization of energy, and improved knowledge of biochar impacts on ecosystem health... |

| Resumo: Diversas metodologias têm sido utilizadas para avaliar os impactos dos pesticidas utilizados na agricultura. O PestLCI Consensus v.1.0, ferramenta apresentada neste trabalho, traz contribuições para a estimativa de emissões de pesticidas em processos agrícolas, para a elaboração de inventários para estudos de avaliação do ciclo de vida (ACV), de gestão ambiental, que tem sido aprimorada para incorporar os potenciais impactos desses compostos em sistemas de produção agropecuários. Além da apresentação do PestLCI, este trabalho objetiva também parametrizar cenários de produção agrícola relevantes para o Brasil. Com isso, espera-se o aprimoramento dos estudos de ACV que abordem os possíveis impactos dos pesticidas sobre a saúde humana e meio ambiente. |

| Abstract: Several methodologies have been proposed to assess the impact of pesticides applied to agricultural crops. The PestLCI Consensus v.1.0 tool presented herein helps estimating pesticide ewwmissions in agricultural processes to prepare inventories for life cycle assessment (LCA) studies. This important environmental management tool was improved to enable the incorporation of the potential impacts of these compounds on agricultural production systems. In addition, the present work also aimed to parameterize relevant agricultural production scenarios for Brazil. With this, it is expected to lead to the improvement of LCA studies that address the possible impacts of pesticides on human health and the environment. |

| With sustainability within food systems becoming an increasingly important issue, several approaches that claim to assess the sustainability of farms, farming systems, and supply chains have been developed. Looking more closely at these sustainability impact assessment approaches, we discerned considerable differences between them in terms of scope, the level of assessment, and the precision of indicators used for impact assessment. Our aim was to classify and analyze a range of available sustainability impact assessment approaches with respect to scope and precision. From a total of 35 sustainability assessment approaches, we selected 6 for a detailed comparison. From our analysis, we concluded that there are 3 different types of trade-offs in these... |

| Maize is the most widely cultivated cereal crop worldwide, currently ranked the third most important crop globally after wheat and rice. It is a key staple food in many developing countries. However, maize is produced on a seasonal basis, usually harvest once per year. To maintain a constant supply throughout the year, maize should be properly stored. But this may entail high cost and high-energy consumption, which can contribute significant amounts of greenhouse gas emissions. In this study, three storage capacities (25,000 bu, 250,000 bu and 2,500,000 bu) of maize were evaluated for economic analysis and environmental impact. The results show that the total storage cost per bushel decreased as storage capacity increased (3.68$/bu, 1.89$/bu, and... |
