The recent focus on carbon trading has intensified interest in 'Blue Carbon'-carbon sequestered by coastal vegetated ecosystems, particularly seagrasses. Most information on seagrass carbon storage is derived from studies of a single species, Posidonia oceanica, from the Mediterranean Sea. We surveyed 17 Australian seagrass habitats to assess the variability in their sedimentary organic carbon ...

In search for an efficient means of building up the carbon stock, improving fertility levels and aggregate stability tropical soils optimum crop yield, a field study was carried using different biochars comparing effects with inorganic fertilizer. The were palm bunch biochar (PBB), saw dust (SDM) rice mill husk (RMHB). Treatments consisted 10 t/ha + 0.25t/ha poultry manure (T1), (T2), (T3), 500...

This paper formulates a dynamic model of global carbon consumption in the absence of an effective international agreement. Each period, countries extract carbon from the global ecosystem. A country’s output depends both on its carbon usage and on“stored carbon” in the ecosystem. We characterize Business-as-usual (BAU) equilibria as smooth, Markov Perfect equilibrium profiles of carbon usage acr...

Stock price prediction is an important and challenging problem in stock market analysis. Existing prediction methods either exploit autocorrelation of stock price and its correlation with the supply and demand of stock, or explore predictive indictors exogenous to stock market. In this paper, using transaction record of stocks with identifier of traders, we introduce an index to characterize ma...

Land use change is a huge threat for mangrove ecosystems,which are known their high carbon sequestration and storage capacity.Vegetation restoration efforts often undertaken, but fail to restore optimal ecosystem sequestration. The forest of Perancak Estuary with history project was made the subject this research. objectives include: (i) estimation biomass sediment stock; (ii) comparison restor...

Soil carbon accumulation is largely dependent on net primary productivity. To our knowledge, there have been no studies investigating the dynamics of carbon accumulation in weathered subtropical soils, especially in managed eucalyptus plantations. We quantified the seasonal input of leaf litter, the leaf decomposition rate and soil carbon stocks in an commercial plantation of Eucalyptus saligna...

For the evaluation of changes in the carbon stock of living biomass, two methods are reported in the Good Practice Guidance for Land Use, Land-Use Change, and Forestry: (1) the default method, which requires the biomass carbon loss to be subtracted from the biomass carbon increment for the reporting year; and (2) the stock change method, which requires two consecutive biomass carbon stock inven...
