This work presents the SEEG platform, a 46-year long dataset of greenhouse gas emissions (GHG) in Brazil (1970–2015) providing more than 2 million data records for the Agriculture, Energy, Industry, Waste and Land Use Change Sectors at national and subnational levels. The SEEG dataset was developed by the Climate Observatory, a Brazilian civil society initiative, based on the IPCC guidelines and Brazilian National Inventories embedded with country specific emission factors and processes, raw data from multiple official and non-official sources, and organized together with social and economic indicators. Once completed, the SEEG dataset was converted into a spreadsheet format and shared via web-platform that, by means of simple queries, allows users to search data by emission sources and country and state activities. Because of its effectiveness in producing and making available data on a consistent and accessible basis, SEEG may significantly increase the capacity of civil society, scientists and stakeholders to understand and anticipate trends related to GHG emissions as well as its implications to public policies in Brazil.

RESUMOObjetivou-se com este trabalho avaliar o efeito do tamanho da estaca e a aplicação de ácido indolbutírico (AIB) no enraizamento de Pitaya vermelha . Estacas de Pitaya vermelha foram coletadas de plantas matrizes e padronizadas com 15,0 e 25,0 cm de comprimento, sendo que metade da quantidade das estacas foi imersa em solução de 3000 mg L -1 de AIB por vinte segundos (imersão rápida) e a outra metade não. Posteriormente, as estacas foram colocadas em canteiro contendo mistura de terra + esterco de curral (3:1 v/v) como substrato. Após 60 dias, foram avaliados as porcentagens de estacas enraizadas e de estacas vivas, e o número de raízes emitidas por estaca. Como conclusão observou-se que o AIB aumentou a porcentagem de estacas enraizadas e promoveu a melhoria da qualidade do sistema radicular das estacas de pitaya vermelha. As estacas de 25,0 cm de comprimento foram mais promissoras para a produção de mudas. Termos para indexação: Hylocereus undatus, estacas e AIB. ABSTRACTThis work was carried with the objective to evaluate the cutting length and application of IBA in rooting of red pitaya cutting. The pitaya cutting were collected of stock plant and standardized with 15.0 and 25.0 cm of length and half of the amount of the cuttings received treatment with 3000 mg L -1 of IBA for twenty seconds. Later the cuttings were placed in stonemason containing a soil mixture + corral manure (3:1 v/v) as substrate. After 60 days, the rooting and survival percentage and number of roots emitted by cutting were evaluated. As conclusion, were observed that IBA increased the rooting percentage and promoted the improvement of the quality of roots of red pitaya cuttings.

Increased production of Brazilian beef has been associated with negative impacts in the Amazon region. Supply chain interventions are increasingly common to avoid social and environmental consequences in the area, but evidence about how companies have managed these efforts is scarce. The present study identified the main sources of reputational risks in Brazilian Amazon beef supply chains and the actions taken by slaughterhouses to manage these types of risk. A multiple case study was developed in Brazilian beef supply chains that have suffered consequences to their operations from consecutive actions of stakeholders that link meat production with deforestation and the worst practices of production in the Amazon region. Public agreements with stakeholders and the development of supplier management were used to identify reputational risks. The present study also describes the types of risk and how they are mitigated. Based on the results, the authors propose a set of risk management practices in the supply chains to manage risks through stakeholder engagement, use of government open data sources, and sharing information with direct suppliers.

Animal production systems and agribusiness Full-length research article Plurality of governance on cattle ranches: case studies in Brazil ABSTRACT-The present article investigated the plural forms of governance that have been adopted in buying and selling transactions by cattle ranches with differentiated markets. In addition, it proposes to describe and explain which determinants influence this plurality, based on the theoretical principles of transaction cost economics. The analysis was based on the observation of both upstream transactions and commitments and agreements established downstream by two ranches, both specialized in beef cattle, but with different competitive strategies. The adoption of plural forms demonstrates diverse competitive advantages, insofar as both can meet the requirements of different distribution channels or increase production capacity. The results indicated that the governance structures adopted by the ranchers studied responded to the demands of the strategies adopted for their production units. Thus, the adopted governance structures should be aligned with their strategies for the cattle ranches to be successful.
