“…Across the land uses, total mean C stocks range from 28.62 ± 13 t ha -1 in AL to 477.82 ± 39.5 t ha -1 in PCDF. The differences of C stocks in different land uses are consistent with Sharma and Rai (2007).…”

Changes in land use cover, particularly from forest to agriculture, is a major contributing factor in increasing carbon dioxide (CO 2 ) level in the atmosphere. Using satellite images of 1999 and 2011, land use and land use changes in the Kumrat valley KPK, Pakistan, were determined: a net decrease of 11.56 and 7.46 % occurred in forest and rangeland, while 100 % increase occurred in agriculture land (AL). Biomass in different land uses, forest land (FL), AL, and range land (RL) was determined by field inventory. From the biomass data, the amount of carbon was calculated, considering 50 % of the biomass as carbon. Soil carbon was also determined to a depth of 0-15 and 16-30 cm. The average carbon stocks (C stocks) in all land uses ranged from 28.62 ± 13.8 t ha -1 in AL to 486.6 ± 32.4 t ha -1 in pure Cedrus deodara forest. The results of the study confirmed that forest soil and vegetation stored the maximum amount of carbon followed by RL. Conversion of FL and RL to AL not only leads to total loss of about 56 % (from FL conversion) and 37 % (RL conversion) of soil carbon in the last decades but also the loss of a valuable carbon sink. In order to meet the emissions reduction obligations of the Kyoto Protocol, Conservation of forest and RL in the mountainous regions of the Hindu Kush will help Pakistan to meet its emissions reduction goals under the Kyoto Protocol.

“…Zang et al (2012) pointed out that soil disturbance due to site preparation and tree planting reduces soil carbon. Sharma and Rai (2007) reported that soil carbon loss is greater (92 %) in cropped areas as compared to forests due to disturbances. The grass land conversion to cropland decreases carbon content in soil (Yan et al 2009).…”

“…Soil organic carbon is the most important part of the terrestrial carbon pool and plays a crucial role in the global carbon cycle (Tang et al 2006;Zhang et al 2008), containing about twice as much carbon as the atmospheric CO 2 reservoir (Percival et al 2000). It is essential, therefore, to better understand the dynamics of soil carbon (Post and Kwon 2000;Sharma and Rai 2007), and its contribution to carbon storage in systems such as shrub communities.…”

Carbon storage is one of the several important functions of shrub communities in terrestrial ecosystems and could represent an effective way to mitigate climate change. Accordingly, biomass carbon (above and belowground), litter carbon, and soil organic carbon (SOC) were studied in three shrub species: Cistus ladanifer (C. ladanifer), Cytisus multiflorus (C. multiflorus), and Erica australis spp. Aragonensis (E. australis)-representing dominant shrub communities found in Montesinho Natural Park (PNM), NE Portugal. The experimental design envisaged testing the effects of species and topography on variables mentioned and procedures carried out included assessments in areas covered by the three communities mentioned, in different topographic conditions (gentle slope, about 5 %; moderate, around 15 %; steep, around 25 %), with three replicates. Above and belowground biomass and litter were collected in 1 m2 plots, where soil samples at depths of 0-5, 5-10, and 10-20 cm were taken (disturbed for C mass concentration, undisturbed for bulk density determinations). The aboveground biomass was separated in stems, branches, branchlets, leaves, and fruits. Carbon mass concentrations determined in biomass, litter, and soil were converted to kg C m -2 ground area. Results showed that: (1) under the conditions studied, over 80 % of carbon is stored in the soil; (2) the contribution of biomass is higher in E. australis, representing about 20 % of carbon storage in the system; (3) for total carbon storage in the whole system, species followed the pattern E. australis (12.8 kg C m ); (4) effects of topographic conditions were not significant in the global C storage, with 10.6, 11.6, and 11.7 kg C m -2 in gentle slope, moderate, and steep, respectively.

“…Forest conversion to other uses releases C to the atmosphere and influence the provision of services underlying carbon sequestration (Feddema et al, 2005;Metzger et al, 2006;Schulp et al, 2008) since different ecosystems differ in potential rates of carbon sequestration. For instance, the conversion from forests to croplands or vice versa has a strong bearing on carbon budgets (Silver et al, 2000;Niu and Duiker, 2006;Sharma and Rai, 2007;Don et al, 2009).…”
