  1. 1. Heat exposure and health outcomes in Costa Rican sugarcane harvesters

    Author : Jennifer Crowe; Maria Nilsson; Tord Kjellström; Catharina Wesseling; Linda Forst; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Agricultural worker; Central America; Chronic kidney disease; Climate change; Dehydration; Heat; Heat illness; Heat stress; Sugarcane; Urinalysis; Worker health; folkhälsa; Public health; Epidemiology; epidemiologi;

    Abstract : Background The remarkably efficient mechanisms of the human body to maintain its core temperature of 37°C can be inadequate when harsh climatic conditions and excessive muscle movement lead to heat stress, dehydration and potential heat illness, ranging from minor symptoms such as fatigue to a potentially fatal heat stroke. Agricultural workers in the tropics are at high risk, which is expected to increase with climate change. READ MORE

  2. 2. Frame Analysis in Environmental Conflicts : The case of ethanol production in Brazil

    Author : Ester Galli; Ronald Wennersten; Tom Dwyer; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Brazil; biodiversity; biofuel; CO2 emissions; environmental conflict; ethanol; frame; frame analysis; land use change; sugarcane; sugarcane cutters; sustainable energy;

    Abstract : Governments and policy-makers are currently dealing with some key issues as energy security in countries dependent on oil imports; global economic development, including increased food production; and controlling global climate change and greenhouse gas emissions. The perception that biofuel could solve these challenges simultaneously has led to the implementation of policy and regulatory mechanisms on the mandatory use of biofuels, resulting in a sharp increase in biofuel production and consumption.

  3. 3. COMMERCIAL SUGARCANE FARMING AND RURAL YOUTH LIVELIHOODS IN EASTERN UGANDA

    Author : Kassim Mwanika; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Youth; Livelihoods; sugarcane farming;

    Abstract : Commercial farming is a pathway for pro-poor growth because of its economic linkages such as jobs and incomes. However, most of the available studies of commercial farming are largely generic, leaving a dearth of evidence about what it means for population categories such as the youth. READ MORE

  4. 4. Environmental Assessment of Emerging Routes to Biomass Based Chemicals The Case of Ethylene

    Author : Christin Liptow; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; sugarcane; time lags; gasification; biomass based chemicals; wood; land use; life cycle assessment; ethylene; LCA;

    Abstract : The production of bulk chemicals from biomass instead of fossil resources is perceived as one promising option to decrease society's environmental impact. However, though considerable research and development efforts aim at such production, it might take several more years before biomass based bulk chemicals are fully commercialized. READ MORE

  5. 5. Lignocellulosic Ethanol Production: Studies on Sugarcane Bagasse, Paja Brava, Wheat Straw, Quinoa Stalks and Curupaú

    Author : Cristhian Carrasco; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam pretreatment; ethanol production; SSCF; arabinosylated aromatics; SO2; H2SO4; sugarcane bagasse; paja brava; wheat straw; quinoa stalks; Anadenanthera colubrina;

    Abstract : Lignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. READ MORE
