Carbon sequestration in dryland ecosystems.
Drylands occupy 6.15 billion hectares (Bha) or 47.2% of the world's land area. Of this, 3.5 to 4.0 Bha (57%-65%) are either desertified or prone to desertification. Despite the low soil organic carbon (SOC) concentration, total SOC pool of soils of the drylands is 241 Pg (1 Pg = petagram = 10(15)g = 1 billion metric ton) or 15.5% of the world's total of 1550 Pg to 1-meter depth. Desertification...
متن کاملestimation of aboveground biomass carbon sequestration potential in rangeland ecosystems of iran
ongoing climate change has been a major global challenge since the 1880s. sequestration of carbon(c) in rangelands ecosystems could provide a net carbon sink to offset increases in atmospheric c in global scale. this research is aimed at estimating the above-ground biomass carbon sequestration potential in iran. for this purpose, total rangelands area and productivity data were extracted from t...
متن کاملThe Terrestrial Carbon Cycle: Managing Forest Ecosystems
The accumulation of CO2 in the atmosphere due to fossil fuel use, deforestation and other anthropogenic sources is changing the global climate (Harries et al. 2001; IPCC 2002). Current understanding of the global carbon cycle suggests that managing forests and agricultural lands to increase the sequestration of greenhouse gases (GHG) provide credible policy options (Dixon and Turner 1991, Winju...
متن کاملGenetic and Molecular Controls on Carbon Sequestration – Implications for Terrestrial Ecosystems
Carbon sequestration in terrestrial vegetation and soils is a poorly understood process, but ultimately represents a summation of biological activities including the initial incorporation of atmospheric CO2 into plant carbohydrates through photosynthesis, carbon partitioning to chemical forms of organic matter resistant to microbial decomposition and carbon allocation to recalcitrant pools of b...
متن کاملCarbon Sequestration in Central European Forest Ecosystems
The forests of Central Europe play an important role in the retention of atmospheric carbon dioxide. Carbon sequestration is rarely the main objective of forest management and is often an underappreciated by-effect of practical forest management, whereas timber production and protection against natural hazards in mountain regions are the main forest functions. Climate change is expected to alte...
