“…Biomass allocation, which reflects the fundamental trade-off in partitioning between above-ground biomass (AGB) and below-ground biomass (BGB) in plants, plays an important role in plant life cycles (Müller et al, 2000;Weiner, 2004;Cella and Bisigato, 2010;Oliveira et al, 2018). Biomass allocation within a plant, particularly the distribution of biomass among the various organs, is strongly affected by species characteristics, ontogeny and the environment where the plants live (Poorter and Nagel, 2000).…”

Biomass allocation patterns among plant species are related to their adaptive ecological strategies. Ephemeral, ephemeroid and annual plant life forms represent three typical growth strategies of plants that grow in autumn and early spring in the cold deserts of China. These plants play an important role in reducing wind velocity in the desert areas. However, despite numerous studies, the strategies of biomass allocation among plant species with these three life forms remain contentious. In this study, we conducted a preliminary quadrat study during 2014-2016 in the southern part of the Gurbantunggut Desert, China, to investigate the allocation patterns of above-ground biomass (AGB) and below-ground biomass (BGB) at the individual level in 17 ephemeral, 3 ephemeroid and 4 annual plant species. Since ephemeral plants can germinate in autumn, we also compared biomass allocation patterns between plants that germinated in autumn 2015 and spring 2016 for 4 common ephemeral species. The healthy mature individual plants of each species were sampled and the AGB, BGB, total biomass (TB), leaf mass ratio (LMR) and root/shoot ratio (R/S) were calculated for 201 sample quadrats in the study area. We also studied the relationships between AGB and BGB of plants with the three different life forms (ephemeral, ephemeroid and annual). The mean AGB values of ephemeral, ephemeroid and annual plants were 0.806, 3.759 and 1.546 g/plant, respectively, and the mean BGB values were 0.106, 4.996 and 0.166 g/plant, respectively. The mean R/S value was significantly higher in ephemeroid plants (1.675) than in ephemeral (0.154) and annual (0.147) plants. The mean LMR was the highest in annual plants, followed by ephemeroid plants and ephemeral plants, reflecting the fact that annual plants allocate more biomass to leaves, associated with their longer life span. Biomass of ephemeral plants that germinated in autumn was significantly higher than those of corresponding plants that germinated in spring in terms of AGB, BGB and TB. However, the R/S value was similar in plants that germinated in autumn and spring. The slope of regression relationship between AGB and BGB differed significantly among the three plant life forms. These results support different biomass allocation hypotheses. Specifically, at the individual level, the AGB and BGB partitioning supports the allometric hypothesis for ephemeroid and annual plants and the isometric hypothesis for ephemeral plants.

“…Belowground biomass in SRC is assumed 30% of aboveground biomass. Although data in the literature show considerable ranges of root‐to‐shoot ratios (Berhongaray, Verlinden, Broeckx, Janssens, & Ceulemans, ; Das & Chaturvedi, ; Heilman, Ekuan, & Fogle, ; Oliveira et al, ; Saugier, Roy, & Mooney, ), this ratio appears as a reasonable estimate. Dead wood is generally disregarded in IPCC Tier 1 methods and thus also not taken into account here.…”

Natural climate solutions versus bioenergy: Can carbon benefits of natural succession compete with bioenergy from short rotation coppice?

et al. 2019

Short rotation plantations are often considered as holding vast potentials for future global bioenergy supply. In contrast to raising biomass harvests in forests, purpose‐grown biomass does not interfere with forest carbon (C) stocks. Provided that agricultural land can be diverted from food and feed production without impairing food security, energy plantations on current agricultural land appear as a beneficial option in terms of renewable, climate‐friendly energy supply. However, instead of supporting energy plantations, land could also be devoted to natural succession. It then acts as a long‐term C sink which also results in C benefits. We here compare the sink strength of natural succession on arable land with the C saving effects of bioenergy from plantations. Using geographically explicit data on global cropland distribution among climate and ecological zones, regionally specific C accumulation rates are calculated with IPCC default methods and values. C savings from bioenergy are given for a range of displacement factors (DFs), acknowledging the varying efficiency of bioenergy routes and technologies in fossil fuel displacement. A uniform spatial pattern is assumed for succession and bioenergy plantations, and the considered timeframes range from 20 to 100 years. For many parameter settings—in particular, longer timeframes and high DFs—bioenergy yields higher cumulative C savings than natural succession. Still, if woody biomass displaces liquid transport fuels or natural gas‐based electricity generation, natural succession is competitive or even superior for timeframes of 20–50 years. This finding has strong implications with climate and environmental policies: Freeing land for natural succession is a worthwhile low‐cost natural climate solution that has many co‐benefits for biodiversity and other ecosystem services. A considerable risk, however, is C stock losses (i.e., emissions) due to disturbances or land conversion at a later time.

“…The average of above-ground carbon storage in gliricidia plantation was 31.91 Mg C/ha. The above-ground carbon storage in the short rotation coppice system for the poplar plantation at the temperate zone reached 3.89 -6.48 Mg C/ha [22]. Hence, above-ground carbon storage in tropical is higher than the temperate zone.…”

The development of gliricidia plantation (Gliricidia sepium) in Indonesia can be considered as a climate change mitigation action to reduce greenhouse gases emission. This paper investigates the yield regulation and potential above-ground carbon storage of gliricidia at Perhutani Forest Management Unit Semarang. The biomass production of gliricidia at various age (1, 2, 3, 4, 5 years) can be utilized to determine the biological cycle and estimating the potential above-ground carbon storage. The result showed that gliricidia could be harvested after 2-years to produce optimum biomass. Above-ground carbon storage in gliricidia plantation distributed in the tree (94.73%), litter (2.98%), and understorey plants (2.29%). Total above-ground carbon storage in gliricidia plantation at age 1-5 years are 6.285,45 Mg C, 8.052,58 Mg C, 9.161,93 Mg C, 14.238,63 Mg C, and 25.474,79 Mg C, respectively.
