“…The probable reason for high CO2 equivalent in the study area may be due to the denser plantation at IIFM campus at Bhopal which is situated in the more isolated safe and secure environment than on other polluted roads in industrialized cities like Kohlapur and Vadodara. However, our results are on the lower side than those obtained in two studies conducted in urban forest ecosystems of Delhi as depicted from the study by Meena et al (2019) for standing biomass carbon content as 41.87 Mg ha -1 and 49.58 Mg ha -1 as reported by Tripathi and Joshi (2015). These two studies were conducted in Delhi ridge natural urban forest ecosystem and human-made urban park/gardens of Delhi respectively, where stem density and average DBH were on the higher side than the present study.…”

In the present article, we have discussed one such example from Indian Institute of Forest Management, Bhopal campus where the amount of carbon stored, and carbon dioxide sequestered by the trees along roadside has been estimated. Importance Value Index was calculated separately for each species. Biomass and carbon stock of woody vegetation was assessed using a non-destructive method. Leucaena leucocephala, Schleichera oleosa, Dalbergia paniculata, Acacia catechu and Ficus religiosa recorded high biomass carbon content. The average stem density was 295 stems ha-1. Species-wise calculated average CO2 equivalent in the sample observed increasing trend with the increase in girth class from 20cm to 60cm but showing reduced trend in trees with girth class above 60 cm. The probable reason for reducing trend could be the variation in wood density of species towards the lower value of high girth size species such as Bombax ceiba, Samanea saman, Holoptelea integrifolia, Dalbergia paniculata, Lagerstroemia parviflora and Ficus religiosa. The analysis can be useful for selection of tree species with high wood density for planting in urban areas of central India to adequately mitigate pollution, especially the vehicular pollution. The incorporation of the same in the management plan of the urban green spaces would benefit the optimum utilization of carbon sequestration potential. Moreover, the suitable bamboo species, which is characterized as species of the understory of tropical dry deciduous forests, may be considered for the planting as gap filing and sequestration of carbon in urban areas.

“…The Cstock by forest (105. 16 t ha −1 ) is also comparable to Delhi urban forest biomass range 107-169 t ha −1 [66]. However, the Cstock of forest is on the higher side as compared to forest plantation in Italian cities (99 t ha −1 ) studied by [67] [67]and Shenyang urban forests with 33 t ha −1 studied by Liu and authors [68] [68].…”

Nagpur is rapidly urbanizing, and in the process witnessing decline in its green status which is one of the identities of the city. The study aims to understand the current species diversity, composition and structure in different classes of greens prevalent in the city. As urban green spaces (UGS) are also reservoirs of carbon stock, the study estimates their biomass. Through rigorous field work, data were collected from 246 sample plots across various UGS classes as pre-stratification. Then the biomass was estimated using non-destructive method with species-specific equation. The diversity of tree species recorded in UGS varies, with high diversity recorded in avenue plantation and institutional compounds. The overall variation in species composition among UGS classes was 36.8%. While in managed greens the species composition was similar, in institutional greens and forest it was different. Particularly, in forest the evenness was high with low diversity and low species richness. The structural distribution indicate lack of old trees in the city, with high number of tree species between diameter classes of 10–40 cm. Biomass was recorded high in road-side plantations (335 t ha−1) and playgrounds (324 t ha−1), and trees with bigger girth size where the main contributors. The dominant species indicates that high growth rate, tolerance to drought and pollution are the key attributes considered for species selection by local authorities. Though the city holds green image, vegetation along the avenues and institutions are stressed, exposed, and threatened by felling activities for grey infrastructure expansions. In such scenario, protection and preservation of older trees is crucial to maintain the carbon stock of the city. In addition, local authorities need to focus on effective afforestation programs through public participation to achieve high survival rate and reduce the maintenance cost. For species selection in addition to phenology and growth rate, tree biomass and life span needs to be considered to significantly enhance the urban environment and increase the benefits derived from UGS.

“…However, under the MFC, P. juliflora was found to be the most dominant tree species with the highest TD (200 individuals ha −1 ), but other associated tree species viz., Pongamia pinnata L. (50 individuals ha −1 ), Azadirachta indica Juss. (50 individuals ha −1 ), A. nilotica (75 individuals ha −1 ), and C. fistula (25 individuals ha −1 ) were also observed (Meena et al 2019). The maximum basal area (BA) values were estimated for A. nilotica (160.52 m 2 ha −1 ) and C. fistula (147.37 m 2 ha −1 ), whereas the BA was comparatively low for P. juliflora (95.74 m 2 ha −1 ).…”

Background: Soil respiration (S R) is a critical process for understanding the impact of climatic conditions and land degradation on the carbon cycle in terrestrial ecosystems. We measured the S R and soil environmental factors over 1 year in four land uses with varying levels of disturbance and different vegetation types viz., mixed forest cover (MFC), Prosopis juliflora (Sw.) forest cover (PFC), agricultural field (AF), and vegetable field (VF), in a semi-arid area of Delhi, India. Our primary aim was to assess the effects of soil moisture (S M), soil temperature (S T), and soil microbial activity (S MA) on the S R. Methods: The S R was measured monthly using an LI-6400 with an infrared gas analyser and a soil chamber. The S M was measured using the gravimetric method. The S T (10 cm) was measured with a probe attached to the LI-6400. The S MA was determined by fluorescein diacetate hydrolysis. Results: The S R showed seasonal variations, with the mean annual S R ranging from 3.22 to 5.78 μmol m −2 s −1 and higher S R rates of~15-55% in the cultivated fields (AF, VF) than in the forest sites (MFC, PFC). The VF had significantly higher S R (P < 0.05) than the other land uses (AF, PFC, MFC), which did not vary significantly from one another in S R (P < 0.05). The repeated measures ANOVA evaluated the significant differences (P < 0.05) in the S R for high precipitation months (July, August, September, February). The S M as a single factor showed a strong significant relationship in all the land uses (R 2 = 0.67-0.91, P < 0.001). The effect of the S T on the S R was found to be weak and non-significant in the PFC, MFC, and AF (R 2 = 0.14-0.31; P > 0.05). Contrasting results were observed in the VF, which showed high S R during summer (May; 11.21 μmol m −2 s −1) and a significant exponential relationship with the S T (R 2 = 0.52; P < 0.05). The S R was positively related to the S MA (R 2 = 0.44-0.5; P < 0.001). The interactive equations based on the independent variables S M , S T , and S MA explained 91-95% of the seasonal variation in S R with better model performance in the cultivated land use sites (AF, VF). Conclusion: S M was the key determining factor of the S R in semi-arid ecosystems and explained~90% of the variation. Precipitation increased S R by optimizing the S M and microbial activity. The S MA , along with the other soil factors S M and S T , improved the correlation with S R. Furthermore, the degraded land uses will be more susceptible to temporal variations in S R under changing climatic scenarios, which may influence the carbon balance of these ecosystems.
