Greenhouse gas mitigation potential from green harvested sugarcane scenarios in São Paulo State, Brazil

Brazil is a major sugarcane producer and São Paulo State cultivates 5.5 million hectares, close to 50% of Brazil's sugarcane area. The rapid increase in production has brought into question the sustainability of biofuels, especially considering the greenhouse gas (GHG) emissions associated to the agricultural sector. Despite the significant progress towards the green harvest practices, 1.67 million hectares were still burned in São Paulo State during the 2011 harvest season. Here an emissions inventory for the life cycle of sugarcane agricultural production is estimated using IPCC methodologies, according to the agriculture survey data and remote sensing database. Our hypothesis is that 1.67 million hectares shall be converted from burned to green harvest scenarios up to years 2021 (rate 1), 2014 (rate 2) or 2029 (rate 3). Those conversions would represent a significant GHG mitigation, ranging from 50.5 to 70.9 megatons of carbon dioxide equivalent (Mt CO2eq) up to 2050, depending on the conversion rate and the green harvest systems adopted: conventional (scenario S1) or conservationist management (scenario S2). We show that a green harvest scenario where crop rotation and reduced soil tillage are practiced has a higher mitigation potential (70.9 Mt CO2eq), which is already practiced in some of the sugarcane areas. Here we support the decision to not just stop burning prior to harvest, but also to consider other better practices in sugarcane areas to have a more sustainable sugarcane based ethanol production in the most dense cultivated sugarcane region in Brazil. © 2013 Elsevier Ltd.

Mitigation of the bullwhip effect considering trust and collaboration in supply chain management: a literature review

The aim of this paper is to provide results of trust and collaboration that lead to the mitigation of the bullwhip effect in supply chain management through a systematic literature review. The criterion for its inclusion in the sample of papers was that at least two reviews of the respective subfields were published in peer-reviewed journals between 1990 and 2014. A total of 24 articles were selected. The analysis found that few studies focused on addressing behavioral aspects to reduce the bullwhip effect. Most of them focused on operational and quantitative aspects. These results indicate the need for studies on behavioral aspects in mitigating the bullwhip effect, where trust and collaboration among those involved in the supply chain need to be developed and organized.

Influência da temperatura de armazenamento na qualidade das inflorescências de estrelítzia (strelitzia reginae banks ex aiton)

This work was based to study the influence of the storage temperature (cold and room temperature) in the quality of inflorescences strelitzia. The scapes were selected, labeled and there were zero problems concerning mechanical damage, disease and/or plagues. Subsequently this period, the scapes were moved randomly to recipients with water, in which two postharvest trials were conducted. In experiment 1, the flower scapes were placed in buckets with water from public supply and sanitation department and taken to a cold room at temperature of 7.5 degrees C and RH of 90%, for a twelve day period. For the experiment 2, were kept under the same conditions but at room temperature for a period of six days. In both experiments, the visual analysis: color, gloss, stains (by assigning notes), opening and drop florets (count) were evaluated at intervals of four days in cold and every 48 hours at ambient temperature conditions. In both experiments, the visual analysis: color, gloss, stains (by assigning notes), opening and drop florets (count) were evaluated at intervals of four days in cold and every 48 hours at ambient temperature conditions. The sepal is the organ that showed greater loss in coloration. The variable gloss showed the same pattern for the two experiments. Incidences of stains on the inflorescences occurred in patches at room temperature. The scapes increased number of florets open in cold. This tendency did not occur at room temperature. No were observed differences in the fall of florets. Conclude that the storage temperature does not contribute to postharvest quality of strelitzia.

The impact of physical activity on mitigation of health care costs related to diabetes mellitus: findings from developed and developing settings Diabetes mellitus and physical exercise

Over the last decades, the prevalence of diabetes mellitus (DM) has been increasing globally such that nowadays the disease constitutes an important outcome related to early mortality among adults. In parallel with the high prevalence, healthcare costs related to DM treatment have increased significantly, exacerbating its burden on modern society. The scientific literature points out that obesity and physical inactivity have a central role in the development of most DM cases. In fact, either physical exercise practice or an increase in the level of physical activity, constitute relevant tools in the guidelines for treatment of the disease. On the other hand, the effect of physical activity on the economic consequences of DM is not completely clear. The identification of the actual burden of lifestyle changes on the reduction of healthcare costs related to DM is relevant, primarily for developing nations, where it could represent a cheaper strategy for treating the disease and its complications than paying for drug treatment, which is commonly related to collateral effects. That being said, the prevention of DM and other diseases and consequently the mitigation of the costs related to these outcomes seem to depend essentially on the promotion of healthy habits. The aim of the present review was therefore to discuss recent evidence on the effects of physical activity/exercise on mitigation of health care cost related to DM.
