Environmental Impacts of Emerging Biomass Feedstock Markets: Energy, Agriculture, and the Farmer AgEcon
Dodder, Rebecca S.; Amani, Elobeid; Johnson, Timothy L.; Kaplan, P. Ozge; Kurkalova, Lyubov A.; Secchi, Silvia; Tokgoz, Simla.
The tighter linkages between energy and crop markets due to recent climate and energy legislation in the US have large potential environmental impacts beyond carbon sequestration and climate mitigation. These range from effects on water quality and quantity, soil erosion, habitat and biodiversity preservation. These impacts are very location and management-decision specific, as they are the product of atomistic decisions and depend on soil and landscape specific variables. In order to fully understand the effects of biomass markets, the new and stronger linkages and feedback effects between national- and global-scale energy and commodity markets must be properly understood and identified using an integrated perspective. We discuss the various interactions...

Regeneration of fertile, hexaploid, interspecific hybrids of elephantgrass and pearl millet following treatment of embryogenic calli with antimitotic agents. Repositório Alice
FALEIRO, F. G.; KANNAN, B.; ALTPETER, F..
Abstract: Elephantgrass (Pennisetum purpureum, 2n = 4x = 28) produces large amounts of biomass in tropical and subtropical regions and is considered a prime candidate for lignocellulosic biofuel production. Interspecific hybridization between elephantgrass and pearl millet (Pennisetum glaucum, 2n = 2x = 14) may allow improvement of drought tolerance and biomass quality. These interspecific hybrids are male and female sterile due to their triploid genome (2n = 3x = 21). Chromosome doubling of the triploid hybrids may restore fertility, permitting a backcross with the recurrent or other elephantgrass parents to enhance biomass yield and persistence. In this study, chromosome doubling of productive interspecific hybrids was performed in vitro. Immature...

Socio-environmental impacts of sunflower production as feedstock for biodiesel in southern Minas Gerais/BR. Repositório Alice
RAMOS, N. P.; BUSCHINELLI, C. C. A.; FONTES, L. P.; VIEIRA, H. B.; CASTRO, C.; LEITE, R. M. V. B. C..
The increase in global demand for renewable energy has encouraged, both directly and indirectly, the production of oilseeds, including sunflower, as feedstocks for biodiesel. In this scenario, Brazil stands out for its excellent agronomic and climatic conditions for growing these crops throughout its territory. However, there is still little information about the sustainability of the biodiesel production chain, depending on the source of raw materials and inputs, the rural context and the region where it is produced. Faced with these questions, this study aimed at evaluating the social and environmental impacts, both along the production chain of biodiesel obtained from sunflower, and at the rural establishment level, in the reference context of southern...

Spatio-temporal variability of sugarcane yield efficiency in the state of São Paulo, Brazil. Repositório Alice
MARIN, F. R.; CARVALHO, G. L. de.
The objective of this work was to assess the spatial and temporal variability of sugarcane yield efficiency and yield gap in the state of São Paulo, Brazil, throughout 16 growing seasons, considering climate and soil as main effects, and socioeconomic factors as complementary. An empirical model was used to assess potential and attainable yields, using climate data series from 37 weather stations. Soil effects were analyzed using the concept of production environments associated with a soil aptitude map for sugarcane. Crop yield efficiency increased from 0.42 to 0.58 in the analyzed period (1990/1991 to 2005/2006 crop seasons), and yield gap consequently decreased from 58 to 42%. Climatic factors explained 43% of the variability of sugarcane yield...
