Abstract:: ... Although abiotic CO₂exchange between soil and atmosphere is often observed in deserts, its contribution to carbon balance and accurate response to soil temperature (T ₛ (°C)) are still uncertain. Abiotic soil carbon flux (ASCF) and T ₛ were continuously measured on sterilized soil at 2-day intervals in the Mu Us Desert, northwestern China from May to October in 2012. The results showed that negati ...

Abstract:: ... Soil carbon sequestration, a climate change mitigation option for agriculture, can either increase or decrease as a result of land management change (LMC) and land use change (LUC). To estimate all greenhouse gas (GHG) exchanges associated with various agricultural systems, life cycle assessments (LCAs) are frequently undertaken. To date LCA practitioners have not had a well-defined procedure to a ...

Abstract:: ... Second-generation bioenergy crops, including Short Rotation Forestry (SRF), have the potential to contribute to greenhouse gas (GHG) emissions savings through reduced soil GHG fluxes and greater soil C sequestration. If we are to predict the magnitude of any such GHG benefits a better understanding is needed of the effect of land use change (LUC) on the underlying factors which regulate GHG fluxes ...

Abstract:: ... Whether carbonate weathering could produce a stable carbon sink depends primarily on the utilization of dissolved inorganic carbon (DIC) by aquatic phototrophs (the so-called Biological Carbon Pump-BCP effect). On this basis, water temperature (T), pH, electrical conductivity (EC) and dissolved oxygen (DO) were synchronously monitored at 15-min resolution for one and two days respectively in Janua ...

Abstract:: ... Carbon dioxide (CO2) is the main greenhouse gas; hence, processes are needed to remove it from the environment. Here, CO2 was used as the substrate to generate methane (CH4) by using enriched methanogens after anaerobic enrichment of waste activated sludge (WAS); therefore, we demonstrate that methanogens from WAS have significant potential for converting the greenhouse gas CO2 into the fuel metha ...
