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...

An attempt to estimate the real value of a set of environmental goods and services, particularly forests are needed that at present, various pressures from economic incentives and goals have been the basis for their destruction and deterioration. Therefore, this study tries to investigate the amount of degradation of vegetation and fixed organic carbon per hectare and its value with social cost...

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 ...

Among the un-market services provided by forest ecosystems, absorption and storage of CO2 (Carbon Sequestration) are very important. Today, Greenhouse Effect is regarded as one of the major environmental problems. In present study, the rate of carbon sequestration of Quercus branti in protected region of Shaho located in Kurdistan province, was evaluated and valued. Random systematic Sampling w...

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...

Ecosystem services are defined as those functions of ecosystems that support (directly or indirectly) human welfare. They occur at multiple scales, from climate regulation and carbon sequestration at the global scale, to flood protection, soil formation and nutrient cycling at local and regional scales (Kremen 2005; Table 1). The MIMES project aims to integrate participatory model building, dat...

The carbon sequestration project has sought to increase the empowerment and livelihoods of indigenous peoples with the goal of mobilizing people and involving local communities in the conservation, restoration and exploitation of the principles of natural resources. Therefore, rural livelihood index is one of the most important and important factors used in measuring and evaluating the living c...
