Aim: To estimate the Carbon sequestration potential of trees in Urban green spaces of Pune city. Study Design: The methods suggested by Ravindranath and Ostwald were used for measuring the above and belowground biomass and estimation of carbon pool. Random sampling technique was used to collect soil samples. As the study area were one acre and above, each and every tree was sampled for various parameters. The GPS instrument was used for measuring latitude and longitude of each and every tree. Place and Duration of Study: The gardens developed by Pune Municipal Corporation (total   66 having an area one acre and above) Pune, Three years( from January 2015 to December 2015, January 2016 to December 2016, January 2017 to December 2017) Methodology: The gardens having an area one acre and above were selected for the work. Each and every tree is sampled along with its position on ground by using GPS instrument. Sampling of tree includes measuring Height and Girth at breast height (GBH). Later, the parameters like Volume, Mass, Wood density, Above and Below ground biomass, Total biomass and Total carbon were calculated as per the standard methods given by Ravindranath and Ostwald [1] Soil samples were collected randomly from a depth of 30 cm as it is a zone of highest microbial activity. Walkley‐Black Wet Oxidation method was used to find out soil organic carbon. Results: Total amount of above and belowground carbon sequestered was estimated to be 7,00,507.83 tonnes; litter and deadwood 24,904.05, and soil organic carbon 1879.905; and the sum of all were 7,27,291.785 tonnes. The exotic species sequester 2,69,287.4 tonnes and native sequester 80,966.55 tonnes of carbon. The rates of carbon in active markets are US$ 30 (Thirty dollars) per tonne.  Conclusion: Putting a conservative value of US$ 30 per tonne of CO2 locked in these sampled gardens, this carbon sink of about 7,27,291.785 tonnes of CO2 is worth of US $ 21818753.55 or Indian Rs. 1606733011.422/-It will help in Climate mitigation and reducing the carbon footprints of Pune city.

Impacts Of Climate Change

Urban green spaces, particularly trees, have great potential to sequester carbon from the atmosphere and mitigate the impacts of climate change in cities. Large university campuses offer prominent space where such green spaces can be developed in order to offset the increasing greenhouse gas emissions, as well as other benefits. Amity University, Noida, is spread over 60 acres with dense tree plantations in and around the campus. The present study is a sustainability initiative to inventory the tree species on the campus and assess their total carbon sequestration potential (CSP). The above- and below-ground biomasses were estimated using the non-destructive sampling method. Individual trees on the campus were measured for their height and diameter at breast height (DBH), and estimates of carbon storage were performed using allometric equations. There is a total of 45 different tree species on the campus with the total CSP equivalent to approximately 139.86 tons. The results also reveal that Ficus benjamina was the predominant species on the campus with CSP equivalent to 30.53 tons, followed by Alstonia scholaris with carbon storage of 16.38 tons. The study reports that the ratio of native to exotic species is 22:23 or almost 1:1. The present work highlights the role of urban forests or urban green spaces, not only as ornamental and aesthetic plantations but also in mitigating the impacts of climate change at a local level. Higher education institutes have an important role in expanding their green cover so as to act as local carbon sinks.

Binding Agents

Aggregate stability and carbon (C) sequestration in soils are closely related phenomena. However, high aggregate stability does not always ensure high carbon sequestration to some soil types since other binding agents could dominate other than carbon. Thus, this study aimed to determine the relationship between aggregate stability and carbon sequestration of different tropical soils which basically differ in geology, genesis, and possibly in their dominant aggregating agents. The study selected four representative soil types (Haplic Acrisol, Calcaric Cambisol, Silic Andosol and Haplic Ferralsol) found in Leyte and Samar that were characterized by previous workers. Soil Organic Carbon (SOC) and Aggregate Stability (AS) in dry and wet conditions were quantified using standard procedures. Some pertinent secondary data were also recorded as reference for each soil type. Results revealed that only Silic Andosol showed positive significant correlation (0.93) between aggregate stability and soil organic carbon (SOC). The other soil types showed weak and negative correlation between aggregate stability and SOC; however, their stability revealed a strong positive relationship with inorganic binding agents. Therefore, each soil type reflects a different relationship between aggregate stability in wet condition and SOC and that the variations could be attributed to the differences in the morpho-physical and geochemical nature of the soils. Moreover, SOC is found to greatly influence the aggregate stability in Silic Andosol, thus the soil carbon sequestration potential of this soil type is generally related to its aggregate stability. However, in other soil types like Haplic Acrisol, Calcaric Cambisol, and Haplic Ferralsol, other binding agents like Calcium (Ca) and iron oxides dominate and control the formation and stability of aggregates rather than SOC.
