Abstract As a part of a larger study concerning the carbon sequestration capability by hazelnut orchards in Italy, we analyzed the total amount of carbon dioxide (CO2) removed over the year from the atmosphere through the net assimilation rates in two hazelnut orchards in Piedmont (i.e., the second region in Italy for surface and production). In particular, considering the key role played by the structural traits in affecting carbon sequestration potential, we assessed the impact of two different training systems widely diffused in the region: single trunk in orchardA and bush-like in orchardB. The results showed that plants in orchardA and orchardB sequestered 10.6 ± 1.8 and 25.7 ± 4.2 kg (CO2) plant−1 month−1, respectively. Higher CO2 sequestration in the plants in orchardB was due to their higher leaf area index relative to plants in orchardA. The mean CO2 sequestration from orchardA and orchardB per area was 4.25 ± 1.72 and 8.57 ± 3.41 Mg (CO2) ha−1 month−1, respectively. We also estimated the total amount of CO2 emission by the management over the entire production season in 157.335 kg CO2eq ha−1 by summing the contribution of diesel fuel, machinery and fertilization practices and considering that the total amount of CO2 sequestered by the two hazelnut orchards over the entire study period was estimated in 26 Mg (CO2) ha−1 in orchardA, and in 51 Mg (CO2) ha−1 in orchardB, they had an effective positive role as carbon sink at this local level.

Tropical savannas cover a quarter of the Australian landmass and the biome represents a significant potential carbon sink. However, these savannas are subject to frequent and extensive fire. Fire regimes are likely to affect the productivity and carbon sequestration potential of savannas, through effects on both biomass and carbon emissions. The carbon sequestration potential has been estimated for some savanna sites by quantifying carbon storage in biomass and soil pools, and the fluxes to these pools. Using different techniques, previous work in these savannas has indicated that net ecosystem productivity [NEP, net primary productivity (NPP) less heterotrophic respiration] was about –3 t C ha–1 y–1 (i.e. a carbon sink). However, the impacts of fire were not accounted for in these calculations. Estimates of NEP have been combined with remotely-sensed estimates of area burnt and associated emissions for an extensive area of mesic savanna in Arnhem Land, NT, Australia. Combining NEP estimates with precise fire data provides an estimate of net biome productivity (NBP), a production index that includes carbon loss through disturbance (fire), and is thus a more realistic indicator of sequestration rate from this biome. This preliminary analysis suggests that NBP is approximately –1 t C ha–1 y–1 (i.e. a carbon sink). A reduction in the annual area burnt is likely to increase the sink size. Uncertainties surrounding these estimates of NBP and the implications of these uncertainties for land management in these extensive landscapes are discussed.

Abstract Background：The fast-growing introduced mangrove Sonneratia apetala is widely used for mangrove afforestation and reforestation in China. Some studies suggested that this exotic species outperforms native species in terms of carbon sequestration potential. This study tested the hypothesis that multi-species mangrove plantations might have higher carbon sequestration potential than S. apetala monocultures.Results: Our field measurements at Hanjiang River Estuary (Guangdong province, China) showed that the carbon stock (46.0±3.0 Mg/ha) in S. apetala plantations where the native Kandelia obovata formed an understory shrub layer was slightly higher than that in S. apetala monocultures (36.6±1.3 Mg/ha). Moreover, the carbon stock in monospecific K. obovata stands (106.6±1.4 Mg/ha ) was much larger than that of S. apetala monocultures.Conclusions: Our results show that K. obovata monocultures may have a higher carbon accumulation rate than S. apetala monocultures. Planting K. obovata seedlings in existing S. apetala plantations may enhance the carbon sink associated with these plantations.

The Impact

The impact of cropping systems on soil properties, nutrient availability and their carbon sequestration potential was studied during the years 2014 and 2015 in Shiwalik hills of Himachal Pradesh. The four commonly occurring cropping systems namely vegetable, fruit, cereal crop and agroforestry were selected. Uncultivated land in the region was considered as control. In total, there were five treatments which were replicated six times under randomized block design. The study indicated that the cropping systems in the Shiwalik hills varied significantly (P=0.05) with respect to their impact on soil properties, nutrient availability and carbon sequestration potential. The pH and EC was in the range of 6.04 to 6.90 and 0.094 to 0.138 dSm-1, respectively and were normal in range. Organic carbon and bulk density in surface soils ranged from 8.06 to 9.70 g kg-1 and 1.19 to 1.34 Mg m-3, respectively. The available NPK was highest (267.21, 19.99, 172.42 kg ha-1) under vegetable based cropping system as compared to other systems. Carbon density in surface soil ranged from 11.33 to 15.39 Mg C ha-1 and total carbon sequestered upto 30cm soil depth ranged from 601.96 to 12646.29 Gg. The study indicated that in Shiwalik hills of Himachal Pradesh, the commonly occurring cropping systems did not influence the soil properties and nutrient availability adversely. Agroforestry based cropping system is having highest potential of sequestering soil carbon in Shiwalik hills. Therefore to adapt to changing climatic situation and to mitigate its effect in the region, agroforestry based cropping system need to be encouraged.
