Mixed Plantation

Reforestation plays an important role in the carbon cycle and climate change. However, knowledge of ecosystem carbon sequestration through reforestation with mixed species is limited. Especially in dry hot valley of the Jinsha River, no studies cover total ecosystem carbon sequestration level in mature mixed plantations for a limited area of mixed plantations and difficulty in the sampling of plant roots and deep soil. In this study, carbon sequestration of seven mixed plantations of different ages in dry hot valley of the Jinsha River was investigated with analogous sites method. The results are as follows: 1) Deep soil organic carbon (SOC) storage significantly increased with stand age (p = 0.025), possibly due to fine root exudates and dissolved organic carbon transportation into deep soil and retention. 2) Total biomass carbon storage in the 30-year-old mixed plantation was 77.78 t C ha−1, 54 times reference wasteland and 9 times reference natural recovery shrub-grassland. However, total biomass carbon storage of 30-year-old mixed plantation was insignificantly lower than that of reference natural forest (p = 0.429). After 30 years of reforestation, plantation biomass carbon storage recovered to reference level, and its sequestration rate was 2.54 t C ha−1 yr−1. 3) The total ecosystem carbon storage of 30-year-old mixed plantation was 185.50 t C ha−1, 2.38 times reference wasteland, 2.29 times reference natural recovery shrub grassland, and 29% lower than reference natural forest. It indicated that niche complementary, good stand structure, and characteristics of dominant species Leucaena leucocephala in mixed plantations facilitate more rapid carbon sequestration, especially biomass carbon in the dry hot valley.

This study was carried out to quantify total carbon sequestration in two broad leaved forests (Shorea and Schima-Castanopsis forests) of Palpa district. The inventory for estimating above and below ground biomass of forest was carried out using stratified random sampling. Biomass was calculated using allometric models. Soil samples were taken from soil profile upto 1 m depth for deep soil and up to bed rock for shallow soils at the interval of 20 cm. Walkey and Black method were applied for measuring soil organic carbon. Total biomass carbon in Shorea and Schima-Castanopsis forest was found 101.66 and 44.43 t ha-1 respectively. Soil carbon sequestration in Schima-Castanopsis and Shorea forest was found 130.76 and 126.07 t ha-1 respectively. Total carbon sequestration in Shorea forest was found 1.29 times higher than Schima-Castanopsis forest. The study found that forest types play an important role on total carbon sequestration.

AbstractAlnus acuminata Kunth. (alnus) is widely used in agroforestry systems across the globe and is believed to provide multiple ecosystem services; however, evidence is lacking in agroforestry literature to support the perceived benefits, particularly in Rwanda. To understand carbon sequestration potential and other benefits of alnus, a household survey, tree inventory and destructive sampling were conducted in north-western Rwanda. Over 75% of the respondents had alnus trees in their farms. The trees provide stakes for climbing beans, firewood and timber. They also improve soil fertility and control soil erosion. Farmers had between 130 and 161 alnus trees per hectare with an average height of 7.7 ± 0.59 m and diameter at breast height of 16.3 ± 1.39 cm. The largest biomass proportion was found in stems (70.5%) while branches and leaves stock about 16.5 and 13% of the total biomass, respectively. At farm level, aboveground biomass of alnus trees was estimated to be 27.2 ± 0.7 Mg ha−1 representing 13.6 Mg of carbon (C) per hectare. Biomass carbon increased with tree size, from 7.1 ± 0.2 Mg C ha−1 in 3 years old trees to 34.4 ± 2.2 Mg C ha−1 in 10 years old trees. The converse was observed with elevation; biomass carbon decreased with increasing elevation from 21.4 ± 1.29 Mg C ha−1 at low (2011–2110 m) to 9.6 ± 0.75 Mg C ha−1 in the high elevation (> 2510 m). In conclusion, alnus agroforestry significantly contributes to carbon sequestration, although the magnitude of these benefits varies with tree age and elevation. Planting alnus trees on farms can meet local needs for stakes for climbing beans, wood and soil fertility improvement, as well as the global need for regulation of climate change.

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.

Mixed plantations of Chinese fir (Cunninghamia lanceolata, CL) and five broadleaf tree species (Ailanthus altissima (AA), Betula luminifera (BL), Sapindus mukurossi (SM), Tciliata varpubescens (TV) and Zelkova schnideriana (ZS)) were established. After 5 years, spatial distributions of carbon stocks were studied in Chinese fir monoculture and mixed plantations. Overstory tree carbon storages were significantly lower (P<0.05) in mixed plantations than that in Chinese fir monoculture plantations. Understory vegetation carbon storages were significantly lower (P<0.05) in CL+BL and CL+ZS plantations than in the monoculture plantations. No significant difference was observed between other mixed plantations and monoculture plantations. Litter carbon storage was significantly lower in CL+ZS plantations than in the monoculture plantations (P<0.05), there was no significant difference between other mixed plantations and monoculture plantations. Soil carbon storages (0-60 cm) in mixed plantations were higher than that in the monoculture plantations, except for CL+SM plantations. Total ecosystem carbon storage was no significant difference between monoculture and mixed plantations, except for CL+SM plantations. Nevertheless, spatial distribution of carbon storage was different among these mixed plantations.

According to the forest resources inventory data for different periods and the latest estimation parameters of forest carbon reserves in China, the carbon reserves and carbon density of forest biomass in the Tibet Autonomous Region from 1999 to 2019 were estimated using the IPCC international carbon reserves estimation model. The results showed that, during the past 20 years, the forest area, forest stock, and biomass carbon storage in Tibet have been steadily increasing, with an average annual increase of 1.85×104 hm2, 0.033×107 m3, and 0.22×107 t, respectively. Influenced by geographical conditions and the natural environment, the forest area and biomass carbon storage gradually increased from the northwest to the southeast, particularly in Linzhi and Changdu, where there are many primitive forests, which serve as important carbon sinks in Tibet. In terms of the composition of tree species, coniferous forests are dominant in Tibet, particularly those containing Abies fabri, Picea asperata, and Pinus densata, which comprise approximately 45% of the total forest area in Tibet. The ecological location of Tibet has resulted in the area being dominated by shelter forest, comprising 68.76% of the total area, 64.72% of the total forest stock, and 66.34% of the total biomass carbon reserves. The biomass carbon storage was observed to first increase and then decrease with increasing forest age, which is primarily caused by tree growth characteristics. In over-mature forests, trees’ photosynthesis decreases along with their accumulation of organic matter, and the trees can die. In addition, this study also observed that the proportion of mature and over-mature forest in Tibet is excessively large, which is not conducive to the sustainable development of forestry in the region. This problem should be addressed in future management and utilization activities.

Nine Latin American countries plan to use silvopastoral practices—incorporating trees into grazing lands—to mitigate climate change. However, the cumulative potential of scaling up silvopastoral systems at national levels is not well quantified. Here, we combined previously published tree cover data based on 250 m resolution MODIS satellite remote sensing imagery for 2000–2017 with ecofloristic zone carbon stock estimates to calculate historical and potential future tree biomass carbon storage in Colombian grasslands. Between 2000 and 2017, tree cover across all Colombian grasslands increased from 15% to 18%, with total biomass carbon (TBC) stocks increasing from 0.41 to 0.48 Pg. The range in 2017 carbon stock values in grasslands based on ecofloristic zones (5 to 122 Mg ha−1) suggests a potential for further increase. Increasing all carbon stocks to the current median and 75th percentile levels for the respective eco-floristic zone would increase TBC stocks by about 0.06 and 0.15 Pg, respectively. Incorporated into national C accounting, such Tier 2 estimates can set realistic targets for silvopastoral systems in nationally determined contributions (NDCs) and nationally appropriate mitigation actions (NAMAs) implementation plans in Colombia and other Latin American countries with similar contexts.

Abstract BackgroundTropical agroforestry systems can contribute incredible benefit for carbon sequestration and plant diversity. This system is one of the common practices in the Central part of Ethiopia. This is because of source of the multifunctional ecosystem services, such as food, feed, biodiversity conservation and carbon storage potential. MethodologyThis study was carried out to assess the influence of land size on floristic diversity, richness and biomass carbon stock. The homegardens were classified into small (<0.06 ha), medium (0.06–0.1 ha) and large (>0.1 ha). Biomass of the homegarden was computed using allometric equations.ResultsA total of 39 woody species, belonging to 24 families were recorded in all the study homegardens. Tree density 625.8 tree ha-1 and basal area 17.3 m2ha-1 were highest for small-size HGs. However, large homegarden had more species richness (Margalef Index) per garden (12.4) compared to medium and small size homegarden. Mean biomass carbon ranged from 9 to 89.3 ton ha-1. Mean biomass carbon stock per unit area was higher in small homegarden (49.3 ton ha-1) compared to medium (38.4 ton ha-1) and large (35 ton ha-1). ConclusionsThis result implies that homegarden can serve as both for carbon sequestration and conservation of woody species diversity. However, a specific homegarden management plan is necessary to improve the carbon storage and species diversification to the respective area. The results provide a catalyst the implication of the future potential of homegarden management in carbon storage thereby for climate change adaptation and mitigation purpose.

Abstract The study aims to assess the plant biomass and carbon storage potential of the forests of Shivpuri, Madhya Pradesh, India. The study was carried out in Satanwada Range in Shivpuri Forest Division. A total of 96 quadrats of 10×10 m2 were laid. The non-destructive algometric method was used to estimate carbon sequestration. The results show that Acacia catechu (202 individuals/ha) dominated the forest, followed by Anogeissus pendula (90 individuals/ha). The total biomass of the forest was estimated to be 34.72±0.41t/ha, with Boswellia serrata (7.943t) recording the highest. The minimum biomass was recorded for Grewia sp (0.06t). The highest carbon content was found in B. serrata (3.97t; 25 individuals) followed by A. Catechu (2.92t; 195 individuals). Although A. catechu was dominant in the area, due to its lower girth class and young age, the net carbon storage was less than that of B. serrata. It was found that plots with higher carbon stock had higher species richness than plots composed of single species. Therefore, plantations of mixed native species should be preferred for future restoration activities as they are more efficient in sequestrating carbon than monoculture plantations.
