The present study deals with the assessment of density of trees (D), biomass (B) and carbon sequestration (CS) of trees on three aspects, viz. north-west (NW), north-east (NE) and south-east (SE) at different forest stands dominated by Quercus leucotrichophora, Quercus glauca and Pinus roxburghii in Nainital District Kumoun Himalya. The density of trees, saplings and seedlings across Community forests varied from 420-840, 110-6200 and 3510-11250 individuals ha-1, respectively. Total biomass of trees at different aspects ranged from 253 - 429 t ha-1. Total carbon storage of trees was 120.22 t C ha-1 on NW aspect (Banj Oak forest), 203.57 t C ha-1 on NE aspect (Chir Pine forest) and 157.47 t C ha-1 on SE aspect (Chir Pine forest). The carbon storage as well as biomass storage value is higher on northern aspect. It can be concluded that north aspect play an important role in forest growth and maturity which is required for sustainable development/ sustainability of environment. The huge amount of carbon storage by studied Van Panchayat forest sites will help to minimize CO2 rise in the atmosphere.

Climate change is one of the impending problems that have affected the productivity of agroecosystems which calls for urgent action. Carbon sequestration through agroforestry along altitude in mountainous regions is one of the options to contribute to global climate change mitigation. Three altitudes viz. lower (286-1200m), middle (1200-2000m), and upper (2000-2800m) have been selected in Tehri district. Ten Quadrates (10m × 10 m) were randomly selected from each altitude in agrisilviculture system. At every sampling point, one composite soil sample was taken at 30 cm soil depth for soil organic carbon analysis. For the purpose of woody biomass, Non destructive method and for crop biomass assessment destructive method was employed. Finally, aboveground biomass (AGB), belowground biomass carbon (BGB), Total tree Biomass (TTB), Crop biomass (CB), Total Biomass (TB), Total biomass carbon (TBC), soil organic carbon (SOC), and total carbon stock (TC) status were estimated and variables were compared using one-way analysis of variance (ANOVA).The result indicated that AGB, BGB, TTB, CB , TB, TBC, SOC, and TC varied significantly (p < 0.05) across the altitudes. Results showed that total carbon stock followed the order upper altitude ˃ middle altitudes ˃ lower altitude. The upper altitude (2000-2800 m) AGB, BGB,TTB, TBC,SOC, and TC stock was estimated as 2.11 Mg ha-1 , 0.52 Mg ha-1, 2.63 Mg ha-1, 2.633 Mg ha-1, 1.18 Mg ha-1 , 26.53 Mg ha-1, 38.48 Mg ha-1 respectively, and significantly higher than the other altitudes. It was concluded that agrisilviculture system hold a high potential for carbon storage at temperate zones. Quercus lucotrichophora, Grewia oppositifolia and Melia azadirach contributed maximum carbon storage which may greatly contribute to the climate resilient green economy strategy and their conservation should be promoted.

The forests of Chhattisgarh are very well known for its species richness, diversity, biomass, carbon stock and productivity. The present study was carried out at Katghora forest division under Bilaspur circle of Korba district, Chhattisgarh considering three sites viz., least, moderately and highly disturbed site to estimate biomass and carbon storage in relation to anthropogenic disturbances. For collection of data quadrats were selected under stratified random sampling design. For enumeration of tree and saplings ten quadrats of 10 m × 10 m were laid and each species counted separately. The tree density varies from 100-510 stems ha-1 across study sites. Total biomass in the present study was between 127.69 t ha-1 and 227.71 t ha-1. Total above ground biomass was between 111.20 t ha-1 and 199.42 t ha-1, whereas total below ground biomass varied from 16.49-28.29 t ha-1, respectively. The total carbon storage across the sites were ranged from 55.125 to 98.548 t C ha-1 found higher under least disturbed site and lowest under medium disturbed site. Carbon storage pattern according to girth class followed the similar trend of distribution as was in the case of biomass. It has least proportion in small girth class and maximum storage under the higher girth class. It is evident from the study that disturbances have significant impact on density, vegetation diversity, biomass accumulation and carbon storage pattern. Conservation affords are required to control on disturbances and for the natural recovery of forest ecosystem.

Black-and-white aerial photographs were used to map the lithology, land-use/forest types, and landslide zones (namely old, active, or potential) in a part of Central Himalaya. The landslide and land-use/forest type maps were simultaneously studied, and the frequency distribution of the landslide zones in different land-uses and forest types was estimated. The correlation between the maps indicated the following: In old landslide-affected sites, agriculture was the predominant land-use, followed by Pinus roxburghii forest (≤ 40% crown cover), scrub vegetation, and wasteland (including grassland). The presence of other forests (e.g. forests dominated by climax species such as Shorea robusta at low elevations and Quercus spp. at higher elevations) indicates a high potentiality of recovery of the ecosystems involved, provided biotic (especially anthropic) factors are not too intensive.The active and potential landslide zones were concentrated along geologically active planes, namely thrusts and faults, and/or in the vicinity of toe-erosion of hill-slopes. These two were dominated by P.roxburghii forest (≤ 40% crown cover). The broadleaf forests showed minimal signs of active and potential landslides, perhaps because of their multistratal character which is conducive to minimizing soil-loss compared with the mostly single-storeyed Chir Pine forest. It is, therefore, suggested that the sites should be maintained under a multistratal broadleaf canopy to conserve the soil. Where, however, the Chir Pine forest is already developed, appropriate silvicultural measures may be taken to increase its crown cover to more than 40%.

Total Carbon Stock

Despite the significant contribution of forests in climate change mitigation, studies to establish the potential of sub-tropical forest ecosystems at different aspects in enhancing soil health indicators are only partly known. The study was carried out to quantify vegetation and soil carbon stocks of a natural Chir Pine (Pinus roxburghii) forest at two different aspects (northern and southern) of a typical sub-tropical environment in Nepal. Stratified random sampling was used for forest inventory and soil sample collection. Aboveground forest biomass was calculated using standard allometric models. Soil was sampled up to 60 cm depth and at 20 cm intervals. Walkey and Black method was used to determine soil organic carbon. Total aboveground plant biomass carbon in southern aspect (140.20 t ha-1) was higher compared to that on the northern aspect (115.34 t ha-1). Similarly, soil carbon stock on southern aspect (46.65 t ha-1) was higher than that of northern aspect (42.14 t ha-1). This resulted to total carbon stock on southern and northern aspect of P. roxburghii forest of 186.85 t ha-1 and 157.48 t ha-1 respectively. The total carbon stock of P. roxburghii forest is significantly higher on southern aspect than on northern aspect with p value 0.001 (p<0.05). Hence, we conclude that the southern aspect of the Mahabharat range favour the growth of P. roxburghii forest compared to the northern aspect. However, the contribution of the entire Chir pine forest ecosystem to carbon sequestration and global climate warming mitigation can’t be neglected.

Forest inventory was conducted in 2009 in Kailali and Kanchanpur districts of the Far Western Development Region of Nepal. Altogether 282 circular plots were measured in 38 camp units equaling 0.02% sampling intensity. The average stocking (excluding regeneration) was 1201 number of stems per ha. The mean stem volume was 172 m3 h-1 and biomass was 186.6 tons h-1. Among the important tree species, Sal (Shorea robusta ) exhibited the highest biomass of 89.8 t h-1 and constituted 48.12% of the total stand biomass, followed by Asna (Terminalia tomentosa) 41.0 t h-1 or 21.00% of the total biomass. The biomass portions of other major species were Chirpine (Pinus roxburghii) 6.50%; Haldu (Adina cordifolia) 3.23%; and miscellaneous species 11.57%. Total air-dry biomass, including stem, branches and leaves, of the two districts was calculated at 51.88 million tons, with Kailali having 37.26 million tons and Kanchanpur 14.68 million tons. The total carbon, after conversion, in forest trees of these two districts was 35.02 million tons. Change in mean stem volume, stocking and composition from earlier assessments underscores the need for appropriate silvicultural intervention.

Abstract Ecologically connected ecosystems are considered more resilient to climate change mitigation by storing increased amounts of carbon than individual ecosystems. This study quantified the carbon storage capacity of seagrass (Thalassia hemprichii) meadows that are adjacent to mangroves (MG; Rhizophora apiculate) and without mangroves (WMG) at three locations in tropical Andaman and Nicobar Islands (ANI) of India. The sediment organic matter (OM) carbon (Corg) content was 2-fold higher at the MG sites than WMG sites of all three locations within the top 10 cm. The Corg in the total biomass was higher at MG sites than the biomass at WMG sites. The sediment grain size positively influenced the sediment OM and Corg content. The canopy height of T. hemprichii showed a better relationship with sediment OM and Corg at MG sites. In contrast, the shoot density of T. hemprichii showed a better relationship with sediment OM and Corg at WMG sites. The total carbon in 144 ha of T. hemprichii meadows of all three MG sites was 11031± 5223 Mg C, whereas the carbon in 148 ha of WMG sites was 4921±3725 Mg C. These T. hemprichii meadows of ANI store around 40487±19171 ton of CO2 in the MG sites and 18036 ±13672 ton of CO2 at WMG sites. The social cost of these carbon stored in these T. hemprichii meadows is around US$ 34.82 and 1.5 million at the MG and WMG sites, respectively. This study points out the efficiency of seagrass ecosystems of ANI as carbon sinks and the potential of these connected seascapes in increasing the efficiency of seagrass carbon storage. Therefore, this connectivity approach should be further explored to include these connected ecosystems of India as a nature-based solution for climate change mitigation and adaptation plans.

A number of Avicennia marina mangrove forests exist along the 1134 km stretch of the Saudi Red Sea coast. Three areas, one in each of the north, centre, and south of the coast, were selected for this investigation into the relationship between total biomass (above-ground, AGB, and below-ground, BGB), and biomass carbon stocks of A. marina, along the nutrient availability (combined with a salinity gradient). To estimate the total biomass stock, this research employed equations formulated through a regression approach. Various population characteristics (tree crown diameter, height, and density) and measurements of carbon (C) in the trees were captured, and other measurements were gathered to represent the environmental properties: electrical conductivity (EC), total dissolved solids (TDS), and total phosphorus (TP) and total nitrogen (TN) levels. With this data from the 21 stands and 7 sites of A. marina covered by the three locations chosen along the coast, it was concluded that a discernible influence is exerted by the concentrations of TP and TN in the sea water and sediments over the population characteristics of this plant. The resulting estimates also demonstrated a steady increase in total biomass and total biomass carbon storage from the mangroves in the north toward the south, with values changing overall from 197.9 to 1188.2 Mg DM ha−1 and from 87.6 to 412.5 Mg C ha−1 respectively. This illustrates that the biomasses held by the southern mangroves are 6 times (total) and 4.7 times (total carbon storage) higher than those in the north.

Rahman FA, Qayim I, Wardiatno Y. 2018. Carbon storage variability in seagrass meadows of Marine Poton Bako, EastLombok, West Nusa Tenggara, Indonesia. Biodiversitas 19: 1626-1631. The increase of atmospheric CO2 concentration in the lastdecades leads to global warming, having an adverse effect on the environment condition on the Earth. One of the natural mechanism asan effort to reduce the impact of global warming is carbon absorption and storage through photosynthesis mechanism of seagrassvegetation. Research conducted at Poton Bako, a district in East Lombok was aimed to reveal the composition of seagrass species,density, seagrass coverage, the biomass of seagrass tissue, content of carbon storage in seagrass tissue (above and below substrates),carbon content in seagrass sediments, and estimation of carbon stock in the area. The research included observation of speciescomposition, and the sample was collected from 0.5 m × 0.5 m plot area. The total plot area was 36 on six lanes with the space betweenplots 25 m and between lanes 100 m. Six species from two families were found in the seagrass meadows, i.e., Cymodocea rotundata,Enhalus acoroides, Halophila minor, Holodule uninervis, Thalassia hemprichii and Thalassodendron ciliatum. The three highest totaldensities were C. rotundata 214.67±110.469 stands m-2, T. hemprichii 85.11±41.471 stands m-2, and H. minor 42.22±44.204 stands m-2.Species with the highest coverage value at all observation plots was C. rotundata (33.47±26.748 %), and T. ciliatum had the lowestvalue (2.12±5.071 %). The total biomass was 676.32 g DW m-2 with biomass above substrate 329.94±57.725 g DW m-2 and belowsubstrate 654.88±81.199 g DW m-2. The carbon content of substrate ranged from 0.11% to 0.51% with the average of 0.35±0.081%,which was categorized low. The total average of carbon storage in seagrass was 447.92 g C m-2 comprising 142.77 g C m-2 of theirtissue above substrate and 305.15 g C m-2 below substrate. Regarding the area, the total carbon stored in seagrass meadows with 56.65ha area was 249.27 t C ha-1.
