“…Biomass and carbon stocks are crucial quantitative aspects of forest ecology. The average aboveground biomass in this study was comparably higher than the other studies, For example, reported values are 9.58 ton/ha in Tripura University Campus, Northeast (Deb et al, 2016), 79.125 ton/ha in an urban forest, Jodhpur city, Rajsthan (Uniyal et al, 2022), 64.92 ton/ha in an soil organic carbon stock, in urban green site foothill was 50.82 ton/ha (Pradhan et al, 2022), in main land use of Allada plateau, Southern Benin, West Africa, it was 83 ton/ha (Houssoukpevi et al, 2022), and the value of soil organic carbon stock in an urban park under cold climate conditions, Finland was 104 ton/ha (Linden et al, 2020) (Table 7).…”

“…For the nation's future urbanisation transition, establishing a urban and peri-urban forest in Agartala, Tripura (Majumdar and Selvan, 2018), 40.14 ton/ha in an urban freshwater wetland in Sri Lanka (Dayathilake et al, 2020), 808.9 ton/ha in urban green site foothill, Eastern Himalayas (Pradhan et al, 2022), 220.81 ton/ha in an urban forest patch, Pondicherry (Khadanga and Jayakumar, 2018), and 279 ton/ha in main land use of Allada plateau, Southern Benin, South Africa (Houssoukpevi et al, 2022) (Table 7). The estimated carbon stock was found also higher in this study compared to other Indian urban forest systems, for example, 3.22 ton/ha in Tripura University Campus, Northeast (Deb et al, 2016), 6.85 ton/ha in an urban and periurban forest in Agartala, Tripura (Majumdar and Selvan, 2018), 92.13 ton/ha in Education Institute, Gwalior, Madhya Pradesh (Anjum et al, 2020), 139.11 ton/ha in an urban forest patch, Pondichery (Khadanga and Jayakumar, 2018), 434.72 ton/ha in urban green site foothill, Eastern Himalayas (Pradhan et al, 2022), and 25 ton/ha in an urban park under cold climate conditions, Finland (Linden et al, 2020) (Table 7). Several factors influence biomass and total vegetation carbon, including the age of the forest stand, tree density, diversity, and basal area (Sahoo et al, 2021).…”

The world is undergoing rapid urbanization and experiencing its negative impacts, often due to the loss of urban green infrastructure. This study focuses on the green infrastructure of Varanasi city, India, and analyses current tree species diversity, and carbon storage in aboveground and belowground biomass and soil. The study calculated the biomass of urban green infrastructure because it serves as a carbon stock reservoir. As random sampling, data were collected from 24 sample plots across various urban green infrastructure sites via rigorous fieldwork. The biomass was then recorded using a non-destructive approach and a standard equation by King et al.2006. The diversity of tree species was recorded across urban green infrastructure sites, and was found to be higher in the BHU site, and lower in the MA site. The Pielou’s evenness index and Margellef’s richness index were found to be higher in the BHU site, while they were found to be lower in UPAC and MA sites, respectively. Aboveground biomass and total carbon stock were found to be high in the BLW site, with values of 1939.84 ton/ha and 7806 ton/ha, respectively, with trees having a larger girth circumference being the primary contributors. The findings of this study prove a better understanding of tree species diversity, biomass, and carbon stock of different green infrastructure sites of Varanasi city and generate evidence on how urban green space preservation and green infrastructure development may help to the countries' green economic transformation and sustainable, resilient, and low-carbon cities.

“…The global urban population is increasing, with over 50% of the world's inhabitants currently residing in urban areas and by 2050 is expected to rise up to 70% [1][2][3]. Climate change, identified as one of the major global challenges of the 21st century, is a significant threat to cities [2]. Governments and urban planning authorities are recognizing the urgency of addressing climate change and the existing challenges to implement mitigation and adaptation strategies that ensure collective wellbeing [4,5].…”

Methodological Approaches and Literature Analysis in the Study of Soil Carbon in Urban Green Spaces: A Systematic Review

This review examines methodologies studying soil carbon in urban green spaces, a field requiring higher attention as their ecosystem services are valued and urban mitigation plans against climate change are developed. In the growing global urbanization, urban green spaces play a crucial role as nature-based solutions to address climate challenges, demanding efficient carbon accounting and reduction strategies. In this research, a systematic review was conducted assessing publications from 2021 to 2023 in the databases Web of Science and Scopus. Findings expose the lack of standardization in the methodologies used to study soil carbon in urban green spaces, evidencing in situ measurements at different sampling depths and studies without longitudinal monitoring over time. In addition, studies originated primarily in universities from China, United States and Spain, which focused on carbon in the form of Soil Organic Carbon and Total Carbon. Based on these findings, recommendations are made advocating for the combination and standardizing methodologies. This review offers valuable insights that shed light on an ignore and often overseen issue. Further studies and standardized methodology are needed, to help cities efforts in their pursuit of carbon neutrality by acknowledging the influential role of urban soils, especially green spaces.

“…The concern about global climate change is abundantly reported with a fear that it can potentially restrict the achievement of Millennium Development Goals (Jagermeyr, 2020;Tamang et al, 2021;Pradhan et al, 2022). The impacts of climate change are comparatively intense in the mountainous regions than in the plains (Palomo, 2017;Gioli et al, 2019;Chhogyel et al, 2020).…”

It has been reported that the large cardamom-based traditional agroforestry systems in the Darjeeling Himalaya of West Bengal, India represents a sustainable land use system with a high potential to store and sequester biomass carbon. Therefore, the present study was undertaken to evaluate the changes in tree biomass stock and carbon accumulation of this indigenous system with altitude. The study area was classified into three altitude-classes as low (700–1200 m asl), mid (1200–1700 m asl) and high (> 1700 m asl). The tree biomass and carbon storage for low-, mid- and high-altitude classes was estimated at 630.17 and 296.18 Mg ha− 1, 397.05 and 186.61 Mg ha− 1 and 315.78 and 148.42 Mg ha− 1, respectively. Schima wallichi, Cryptomeria japonica and Cupressus cashmeriana were the most ecologically important tree species based on IVI (important value index) in the low-, mid-, and high-altitude classes, respectively. The IVI and total biomass of the five most ecologically important tree species in low-, mid- and high-altitude ranged from 17.34–26.04, 18.15–37.56, 27.13–42.43 and 9.05-133.75 Mg ha− 1, 1.38–37.43 Mg ha− 1 and 19.0-72.1 Mg ha− 1, respectively. Schima wallichi occurred in all the altitude-classes among the five most ecologically important tree species. In the study area, the average ecosystem carbon storage was estimated at 295.02 Mg ha− 1. The contribution of soil organic carbon to the ecosystem carbon stock increased with the increasing altitude. In contrast, the contribution of biomass carbon to the ecosystem carbon stock decreased with the increase in altitude. The ecosystem carbon stock estimated for the low-altitude class was 36.43% and 45.30% higher than the mid- and high-altitude agroforestry systems. The large cardamom-based agroforestry systems in the Darjeeling Himalayas are thus a prospective carbon sink, both in vegetation and soil due to higher tree densities and natural resource conservation-based traditional farming practices.
