Executive Summary There is widespread recognition of the potential role forests can play in contributing to Green House Gas (GHG) reductions through carbon sequestration. Non-industrial private forests (NIPF) comprise a significant portion of forests in the U.S. (approximately 40%). Thus, it is crucial to assess the role that NIPF landowners can play in broader carbon sequestration efforts. Man...

Carbon sequestration is believed to “buy time” for technical change in the energy sector. To assess rigorously this widespread argument, we build an intertemporal optimization model where both abatement of fossil fuel emissions and biomass sequestration can be used to mitigate climate change. We confirm that permanent sequestration, if feasible, can be a cost-effective part of an overall climat...

Enhanced sequestration of plant-carbon (C) inputs to soil may mitigate rising atmospheric carbon dioxide (CO2) concentrations and related climate change but how this sequestration will respond to anthropogenic nitrogen (N) and phosphorous (P) deposition is uncertain. We couple isotope, soil C fractionation and mesocosm techniques to assess the sequestration of plant-C inputs, and their partitio...

objective(s) the aim of this study was to investigate the presence of per-1-type esbls in drug resistant pseudomonas aeruginosa isolates. materials and methods during one-year period (2008-2009), following isolation and identification of 56 p. aeruginosa, the e-test method was performed for determination of minimal inhibitory concentration of ceftazidim. the isolates that they had mic≥16 µg/ml ...

due to the notable role of different land uses in carbon sequestration and emission, four treatments including rangeland as control, haloxylon plantation area, olea plantation (olive garden), and residential lands, were selected to study the effects of land use change on soil carbon sequestration and emissions in eivanakei rangelands, semnan province. carbon stocks in vegetation and soil of eac...

Carbon dioxide (CO2) sequestration has been proposed as a key component in technological portfolios for managing anthropogenic climate change, since it may provide a faster and cheaper route to significant reductions in atmospheric CO2 concentrations than abating CO2 production. However, CO2 sequestration is not a perfect substitute for CO2 abatement because CO2 may leak back into the atmospher...
