“…Ecosystem carbon stock under large cardamom traditional agroforestry systems estimated was higher than the stock estimated for traditional homegardens, farm forestry and plantation forests (Mulatu, 2019;Tamang et al, 2021;Chettri et al, 2023;Dey et al, 2023).…”

“…Consequently, the vegetation heterogeneity of these under-canopy forest-based large cardamom traditional agroforestry systems is conserved which leads to higher carbon net gain and high ecosystem carbon balance while, making the system more permanent, stable, resilient and productive than any other land use systems in an agricultural landscape (Mulatu, 2019;Rai et al, 2021;Tamang et al, 2021;Chettri et al, 2023;Dey et al, 2023). This traditional practice of forest-based under-canopy large cardamom cultivation can be an efficient adaptation option at Darjeeling Himalayas to mitigate climate change locally and regionally besides the provision of livelihood and ecological benefits to the locals (Lepcha and Devi, 2020;Vineeta et al, 2023).…”

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.

“…Despite the fact that anthropogenic activities have diminished the overall vegetation cover of Ethiopian woodlands [19], the country continues to be a major source of woody species variety. Woody species diversity is highly connected with forests, with notable exceptions such as agroforestry systems [20][21][22] and small-scale portions of plantation stands. Ethiopia has worked for the past 30 years to repair degraded lands for long-term use, employing diverse strategies such as Sustainable Land Management (SLM).…”

Land cover change in Addis Ababa, Ethiopia’s capital, is driven by recurring drought and the economic problems of society-initiated afforestation. The goal of this study was to learn about the state of woody species regeneration in Yeka’s urban forest patches. Thirty plots (20 m × 20 m in size) were sampled to identify plants for this purpose. All wooden trees with a height greater than 1.3 m in each plot were identified, enumerated, and their diameter were measured. Acacia decurrens was determined to be the predominant species, with an importance value index (IVI) of 161.09, followed by Acacia melanoxlon (IVI = 44.69). The bootstrapping PERMANOVA test was used to show how the species in the community overlapped. The result reveals that dissimilarity is low (p > 0.05), which is supported by the assumption of multivariate dispersion homogeneity. The area’s generalized linear model (GLM) showed all species statistically significant for characteristics associated with closure year and presence of mature trees and the entire closure year. Two of the twenty tree species, i.e., Acacia decurrens and Acacia melanoxylon were found in nearly equal numbers in all three growth stages as well as having strong regenerating potential. The rapid expansion of exotic Acacia spp. necessitates careful attention to their regeneration. To reinforce and improve ecosystem services, conservation and restoration efforts should encourage the regeneration of native plant species.
