due to the notable role of different land uses in carbon sequestration and emission, four treatments including rangeland as control, haloxylon plantation area, olea plantation (olive garden), and residential lands, were selected to study the effects of land use change on soil carbon sequestration and emissions in eivanakei rangelands, semnan province. carbon stocks in vegetation and soil of eac...
Land use/cover change is one of the main factors in environmental changes. The changes directly affect the value of ecosystem services. The purpose of this research is to evaluate the effect of land use/land cover change in the Kashkan area on its ecosystem services. This research was carried out in three stages, including the analysis of land cover changes, prediction of changes, and carbon st...
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...
Background and objectives: Organic carbon is one of the important parameters to determine soil fertility, and production ability and is a mind index for showing soil quality, especially in dry and semi-dry lands. The rangelands are composed of about 50 % of the world's lands and have more than 33 % of carbon reservoirs on earth. Considering the ranges as the most important terrestrial ecosystem...
carbon sequestration in soil, leaf and litter of three tree species, viz. eucalyptuscamaldulensis, prosopisjuliflora and ziziphus spina-christi, plantation was investigated in the dehloran city, iran. results showed that the amount of sequestered c in leaf, litter and soil was significantly different among these species. the highest amount of sequestrated c was in leaf and the lowest amount in ...
Climate change is known as one of the most important environmental challenges. Sequestration of carbon in terrestrial ecosystems is a low-cost option that may be available in the near-term to mitigate increasing atmospheric CO2 concentrations, while providing additional benefits. In this study, we estimated the effects of planting density and grazing intensity on the potential of Atriplex canes...
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...
In this study, the economic evaluation of carbon sequestration in plant biomass and soil under three types of livestock grazing intensity was investigated. Three area under light, medium and high grazing intensities in the Inchehbrun salt lands of Golestan province were selected. Soil and plant samples were taken in a systematic-random method. Three 100 meters length parallel transects were ins...
Communities or ecosystems with higher biodiversity also have higher levels of ecosystem function and services, so the relationship between functional diversity and sustainability of plant communities is essential to predict ecosystem functioning. The aim of the present study was to investigate the relationship between carbon stocks and different species diversity and functional indices as well...
To promote the sequestration of blue carbon, resource managers rely on bestmanagement practices that have historically included protecting and restoring vegetated coastal habitats (seagrasses, tidal marshes, and mangroves), but are now beginning to incorporate catchmentlevel approaches. Drawing upon knowledge from a broad range of environmental variables that influence blue carbon sequestration...
