Biofilm-induced mineral precipitation is a fundamentally important phenomenon with many potential applications including carbon sequestration and bioremediation. Based on amixture model consisting of three phases (calcite, biofilm, and solvent) and also accounting for chemistry, mechanics, thermodynamics, fluid, and electrodiffusive transport effects, we describe the self-induced generation of ...

increasing the concentration of atmospheric carbon dioxide is the main factor for the climatic change having some harmful consequences for the human health while there is no considerable effort for decreasing this accelerated global problem, yet. kermanshah province located in the west of iran has about 1,200,000 ha rangeland which is dominated by astragalus sppas the more frequent shrub beinga...

For the past dozen years there has been a growing interest in the possibility of mitigating the global warming effects of carbon dioxide by increasing the carbon stocks of biomass and soils. The earliest economics studies examined the costs of capturing and storing carbon in forest ecosystems (for a review of these studies see Richards and Stokes 2000). Over time, the potential for cost-effecti...

The observed increase in hurricane intensity in the North Atlantic calls for an evaluation of the effects that these storms have on temperate forest ecosystems where much of the terrestrial carbon is sequestered. We use a data-based forest simulator to analyse the effects of both historical and potentially future hurricane disturbance regimes on the structure, dynamics and carbon sequestration ...

The United States Department of Energy (DOE) is the lead federal agency for the development and deployment of carbon sequestration technologies. Its mission includes promoting scientific and technological innovations and transfer of knowledge for safe and permanent storage of CO(2) in the subsurface. To accomplish its mission, DOE is characterizing and classifying potential geologic storage res...

Direct injection of CO2 into the ocean is a potentially effective carbon sequestration strategy. Therefore, we want to understand the effectiveness of oceanic injection and develop the appropriate analytic framework to allow us to compare the effectiveness of this strategy with other carbon management options. Here, after a brief review of direct oceanic injection, we estimate the effectiveness...

the aim of this study was to investigate the effect of reforestation on physical and chemical soil properties particularly soil carbon storage in the berenjastanak forest. forestations were including acer velotinum boiss., fraxinus excelsior l., populus nigra l. and pinus brutia ten. a witness forest with mixed species was selected as region potential. four soil profiles were drilled in each fo...

The mangrove forest ecosystem is known to possess a variety of ecosystem services, including high rates of carbon sequestration, storage and mitigating climate change through reduced deforestation. This study was carried out in the mangrove forests of Gowatr Bay, Gulf of Oman during 2017-18 to quantify biomass and carbon stocks of all components of this forest, including live and dead trees, so...

Since Renaissance, the natural ecosystems have fallen into a complete state ofdisarray due to the rise in the amount of carbon dioxide. Soil, the unsparing stuff, is one of themajor sources of carbon storage, and plays a paramount role in the global equilibrium ofcarbon as well as carbon sequestration. Given that Iran is benefiting from vast steppes, therate of carbon sequestration in them dese...
