“…But there was no signi cant mean difference between soils of grazing and cultivated lands (Table 3). This nding was consistent with the study by Solomon et al (2018) which revealed that CS was highest in forestlands and lowest in cultivated lands. The study conducted in Chilimo, a dry Afromontana forest in Ethiopia, found out higher mean carbon stock in natural forest than any other land cover types (Tesfaye et al, 2018).…”

BackgroundThe decrease in the area under natural vegetation and its conversion into other types of use has resulted in resource degradation including soil quality loss. Soil properties response to changes in land use/ cover has shown spatial and temporal variations. Hence this study was carried out to examine the influence of land use/ cover changes on physical and chemical properties of the soils in Rib watershed. Soil samples were taken over three selected land use/ covers (natural forest, grazing and cultivated lands) in two agro- ecological zones (Dega and High Dega). Multivariate analysis of variance (MNOVA) and Pearson’s correlation was computed. ResultsThe study revealed that land use/ cover and altitude have influenced physical and chemical properties of the soil in the study watershed. Significant difference in distribution of soil texture, BD, OC, TN and pH among land use/ covers have been observed. Natural forest had higher OC, OC stock and TN than grazing and cultivated lands. The mean OC stock ranged from 188.32 t/ha in natural forest to 72.75t/ha in cultivated lands. Soil pH was slightly higher for natural forests and lower in the soils of grazing and cultivated lands. Significant difference (P<0.05) among the two agro ecologies were also observed in OC, Ca2+, clay, and silt.. ConclusionTherefore, land use/ cover changes have affected the concentration of TN, OC, increase soil acidity and compaction that can affect productive of soils and production of crops.

“…The C stored in different pools was estimated as aboveground (29.28 Mg C ha −1 ), roots or belowground (12.59 Mg C ha −1 ), litter (0.26 Mg C ha −1 ), and SOC (21.36 Mg C ha −1 ). The estimated average forest standing biomass C (sum of AGB and BGB), i.e., 41.87 Mg C ha −1 , was lower than the values reported for tropical dry forests of Asia (Gibbs et al 2007;IPCC 2006) and forests from Mexico (Dai et al 2014) and Ethiopia (Solomon et al 2017(Solomon et al , 2018, but higher than forests from Africa (Gibbs et al 2007;IPCC 2006) and Brazil (Júnior et al 2016). Carbon in AGB was also lower than that of a semi-arid (Picea crassifolia) forest in the North Eastern Tibet (Wagner et al 2015).…”

Background: Assessment of carbon pools in semi-arid forests of India is crucial in order to develop a better action plan for management of such ecosystems under global climate change and rapid urbanization. This study, therefore, aims to assess the above-and belowground carbon storage potential of a semi-arid forest ecosystem of Delhi. Methods: For the study, two forest sites were selected, i.e., north ridge (NRF) and central ridge (CRF). Aboveground tree biomass was estimated by using growing stock volume equations developed by Forest Survey of India and specific wood density. Understory biomass was determined by harvest sampling method. Belowground (root) biomass was determined by using a developed equation. For soil organic carbon (SOC), soil samples were collected at 0-10-cm and 10-20-cm depth and carbon content was estimated. Results: The present study estimated 90.51 Mg ha −1 biomass and 63.49 Mg C ha −1 carbon in the semi-arid forest of Delhi, India. The lower diameter classes showed highest tree density, i.e., 240 and 328 individuals ha −1 (11-20 cm), basal area, i.e., 8.7 (31-40 cm) and 6.08 m 2 ha −1 (11-20 cm), and biomass, i.e., 24.25 and 23.57 Mg ha −1 (11-20 cm) in NRF and CRF, respectively. Furthermore, a significant contribution of biomass (7.8 Mg ha −1 ) in DBH class 81-90 cm in NRF suggested the importance of mature trees in biomass and carbon storage. The forests were predominantly occupied by Prosopis juliflora (Sw.) DC which also showed the highest contribution to the (approximately 40%) tree biomass. Carbon allocation was maximum in aboveground (40-49%), followed by soil (29.93-37.7%), belowground or root (20-22%), and litter (0.27-0.59%). Conclusion: Our study suggested plant biomass and soils are the potential pools of carbon storage in these forests. Furthermore, carbon storage in tree biomass was found to be mainly influenced by tree density, basal area, and species diversity. Trees belonging to lower DBH classes are the major carbon sinks in these forests. In the study, native trees contributed to the significant amount of carbon stored in their biomass and soils. The estimated data is important in framing forest management plans and strategies aimed at enhancing carbon sequestration potential of semi-arid forest ecosystems of India.

Tropical forests are rich in biodiversity with great potential for carbon (C) storage. We estimated ecosystem-level C stock using data from 70 forest plots in three major forest types: tropical dry deciduous (TDD I and TDD II), tropical semi-evergreen (TSE I and TSE II) and tropical evergreen forests (TEF I, TEF II and TEF III) of Kanyakumari Wildlife Sanctuary, Western Ghats, India. The average C stock in these forests was 336.8 Mg C/ha, of which 231.3, 3.0, 2.4, 15.2 and 84.9 Mg C/ha were stored in woody vegetation, understorey, litter, deadwood and soil respectively. The live vegetation, detritus and soil contributed 65.5%, 5.5% and 29% respectively to the total ecosystem-level C stock and distributed in forest types in the order: TEF III > TEF II > TEF I > TSE I > TDD II > TSE II > TDD I. The plant diversity, structural attributes and environmental factors showed significant positive correlations with C stocks and accounted for 6.7, 77.2 and 16% of variance. These findings indicate that the tropical forests in the Western Ghats store large amount of C, and resulting data are invaluable for planning and monitoring forest conservation and management programs to enhance C storage in tropical forests.
