carbon is the most important greenhouse element which sequestrates by photosynthesis procedure and is the easiest and cheapest way of decreasing atmospheric gas level. the vegetation cover that has woody texture is more capable for carbon sequestration. the most plant species of arid rangelands are the shrub growth forms. the purpose of this research was to assess carbon sequestration potential...
soil is known as a suitable reservoir for carbon sequestration. the objective of this study was to investigate the capability of haloxylon on sequestration of carbon in sand dunes of yahya abad, sabzevar, in northeastern iran. eighty soil samples were taken from two depths of 0-5 and 5-10 cm under and between haloxylon trees. eight soil profiles under and between haloxylon trees were described ...
Today, climate change and global warming caused by the emission of greenhouse gases is a big challenge to the world, especially in arid and semi-arid area. Afforestation is the most effective strategy to absorb carbon dioxide in terrestrial ecosystems and reduce global warming of the earth. The purpose of this study is to evaluate the effects of planting Eucalyptus camaldulensis and Amygdalus s...
Desertification leads to decrease in the ecosystem C pool and attendant reduction in Soil Organic Carbon (SOC). Reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. Our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...
Examining the economic value of carbon sequestration in forests is essential, given the risk of global climate change, which has posed a profound challenge to societies internationally. The present study investigates the amount of carbon sequestration and its economic value in the oak forests (Quercus brantii L.) of Pahnus forest habitat with an area of 990 ha, located in Chaharmahal va Bakhtia...
carbon sequestration potential of three species including agropyron elengatum, stipa barbata and artemisia aucheri was evaluated in parts of a semi-arid rangeland in this study. after determination and selecting key areas as study sites, sampling from vegetation and soil, based on randomized systematic method, was done and 90 plant and 45 soil samples were taken, respectively. shooting and root...
in recent years, rangelands have been regarded as potential carbon sinks. one of the most widely suggested options to sequester more c in rangelands is the restoration of the degraded rangelands through grazing the exclusion. in present study, the effects of exclusion on the carbon sequestration of gomishan rangelands were investigated. three transects were established in a key area inside and ...
carbon sequestration in soil and plant biomass is the most simple and economic way for co2 decrease that is important in environment improvement. this research was done in miankaleh region of behshahr in mazandaran for comparison of carbon sequestration in different plant types. firstly, plant types were determined and dominant species was identified in each type. number and size of plots was o...
forest ecosystems and their optimal management can play effective roles in mitigating the carbon emission as well as absorbing the atmospheric carbon. the present research was carried out to determine the effects of 21 year old stands of cryptomeria japonica, cupressus sempervirens, pinus taeda, acer pseudo-platanu and mixed plantation and natural forest stands on sequestration of carbon in the...
introduction climate change is one of the most important challenges in sustainable development, which has a negative impact on aquatic and terrestrial ecosystems. this will change rainfall patterns the power to increase hurricane and the risk of drought, flood and will strengthen pressure on water resources. researchers generally agree that the main cause of the increase in global temperature i...
