Carbon sequestration is defined as the process of capturing and storing atmospheric carbon dioxide. Fruit crops are indispensable both for climate change mitigation ensuring food security. However, impact fruit trees not adequately investigated.

Factors influencing tree biomass and carbon stock in the Western Himalayas, India

Frontiers in Forests and Global Change, Journal Year: 2024, Volume and Issue: 6

Published: Jan. 9, 2024

The assessment of tree biomass and its carbon (C) stock at the local regional level is considered a crucial criterion for understanding impact changing environments on global cycle. In this context, we selected three sites in western Himalayas, covering parts Himachal Pradesh north-eastern Haryana. Each study site experiences distinct climatic conditions, vegetation types, elevations. We seek to elucidate determinants across different forest types Western Himalayas. found that temperate forests contributed most stock, with Cedrus deodara attaining highest values 782.6 ± 107.9 Mg/ha 360 49.7 Mg C/ha. contrast, Quercus leucotrichophora mixed had lowest 286.6 57.2 128.9 25.7 Mg/C ha, respectively. Only few species, such as Abies pindrow , floribunda semecarpifolia accounted significant stock. lower elevation subtropical species richness (8–12 species) stem density (558.3 62.9 866.6 57.7 trees/ha). Furthermore, diameter, total basal cover, height emerged strongest predictors C remaining variables showed no associations, including diversity, attributes elevation. Thus, our extended assertion composition structural attributes, apart from topographic factors, are equally important determining ecosystems. Our indicated Himalayas possess storage climate change mitigation potential.

Thinning intensity affects carbon sequestration and release in seasonal freeze–thaw areas

Journal of Forestry Research, Journal Year: 2022, Volume and Issue: 34(4), P. 993 - 1006

Abstract To explore how to respond seasonal freeze–thaw cycles on forest ecosystems in the context of climate change through thinning, we assessed potential impact thinning intensity carbon cycle dynamics. By varying number temperature cycles, effects various intensities four seasons. The rate mass, litter organic carbon, and soil (SOC) loss response variations was examined two degrees decomposition. unfrozen season had highest decomposition litter, followed by frozen season. Semi-decomposed a higher than undecomposed litter. when 10%, while SOC were low. Forest good sequestration seasons, converse confirmed thaw best identified layers under 20–25% intensity, influence more noticeable that semi-decomposed Both can store carbon: however, is transported from over time. In summary, being 20–25%.

The potential for an old-growth forest to store carbon in the topsoil: A case study at Sasso Fratino, Italy

Journal of Forestry Research, Journal Year: 2023, Volume and Issue: 35(1)

Published: Dec. 7, 2023

Abstract There is considerable interest devoted to old-growth forests and their capacity store carbon (C) in biomass soil. Inventories of C stocks are carried out worldwide, although there a lack information on actual potential for sequestration. To further understand this, soil organic (SOC) was measured one Italy’s best-preserved forests, the Sasso Fratino Integral Nature Reserve. This reserve World Heritage List along with other ancient beech Europe, it virtually untouched due steepness terrain, even before legal constraints were imposed. Although sandstone-derived soils often shallow, they rich matter. However, no quantification had been out. By systematically sampling topsoil across forest, we accurately determined average amount SOC (62.0 ± 16.9 Mg ha –1 ) nitrogen (4.0 1.2 top 20 cm.

Understanding recovery times and mechanisms of ecosystem dynamics towards the old-growth stage is crucial for forest restoration, but still poorly delineated in Mediterranean. Through tree-ring methods, we reconstructed return a tall canopy after severe human disturbance mixed beech (Fagus sylvatica) silver fir (Abies alba) forest, located at mountain site southern edge both species' range (Gariglione, south Italy). The primary was extensively harvested between 1930 1950, removing up to 91 % biomass. Growth histories, climate-growth relationships time-series growth dominance Gariglione were compared with network protected mature forests distributed along wide elevational gradient same region. We found that renewed mainly composed remnant trees, which include uncut trees saplings, post-harvesting regeneration mostly represented by fir. Canopy reached maximum basal area increment (BAI) 1970s, 40-50 years cutting. Then, BAI shifted negative trends phase drying climate (PDSI), while maintained sustained until 2000. This asynchrony two species conferred community stability over last decades. comparison highlighted common impact summer drought on high-frequency signals Italy. However, analysis long-term mean indicates decreasing limited beech, revealing relevant differences due ecology its interactions legacy effects past management driving responses change. Indeed, lowland showed increasing decades, high-mountain displayed remarkably stable low oscillating growth.

Improving the carbon storage in terrestrial ecosystems can effectively reduce atmospheric CO2, which is one of important ways mitigating global climate change. The knowledge on stock research relatively mature international community; however, pulse, hotspots, and trends are not clear. To better understand focus developmental directions ecosystems’ storage, we conducted a bibliometric analysis 6305 articles between 2002 2022, were gathered from Web Science Core Database. temporal distribution, country/region co-citation network, keyword evolution clustering, journals, authors literature analyzed, domain was mapped using CiteSpace visualization software. This study established following three observations: (1) number publications continues to expand, trend proves that sinks systems remain an topic internationally. (2) Important issues concerning ecosystem have evolved monitoring changes mechanism formation for realization management under Furthermore, methodology has small-scale, fixed-point instrumental observations large-scale remote sensing model simulations, with diversifications content methodology. (3) In future, academic stocks will more interdisciplinary cooperations, increasing intensity surveying ecosystems, realizing accurate monitoring, assessment, management, enhancement integrated computation system “sky, air, land.” results this comprehensively demonstrate current status development worldwide, provide reference future sustainable within context warming.
