TL;DR: In this paper, the tree cover data produced by the University of Maryland, USA using Landsat satellite imagery was used to assess the tree coverage changes in four cities, namely Penang Island, Kuala Lumpur, Johor Bahru and two cities in Iskandar Malaysia in Peninsular Malaysia.
Abstract: Despite their significant role for biological diversity, ecosystem stability and human comfortability, tree coverage in cities is continuously destructed and degraded to cater to increasing urbanisation in developing countries, including Malaysia Cities are more susceptible to environmental change impacts and become unlivable Thus, monitoring and mapping tree cover is critical (i) for conserving trees and (ii) for making decisions to increase green cover in cities Mapping and monitoring urban green cover can be done routinely using remote sensing technologies In this study, tree cover data produced by the University of Maryland, USA using Landsat satellite imagery was used to assess the tree cover changes in four cities, namely Penang Island, Kuala Lumpur and two cities in Iskandar Malaysia in Peninsular Malaysia The 30 m x 30 m ground resolution tree cover data were overlaid onto the city boundaries to calculate the losses and gains in tree cover relative to the tree cover in the year 2000 Results of the study show that over a period of 12 years (2000-2012), Penang, Kuala Lumpur, Johor Bahru and Pasir Gudang lost about 69 %, 35 %, 95 % and 174 % of tree cover from their total land area Nevertheless, these areas also gained some tree cover over the same period, which resulted in a net loss of 723 ha, 494 ha, 2,366 ha and 3,678 ha From 2012 to 2014, the total loss of tree cover in the 4 cities were 138 ha, 64 ha, 626 ha and 1,159 ha, respectively The loss of tree cover in cities needs to be controlled and efforts should be taken to plant more trees in Malaysia Although the importance of green space within urban areas is more noticeable recently in Malaysia, no specific policies and legislation relevant to the protection and management of urban forests are available Clear and detailed urban forest strategies and policies must be formulated to protect, plant and manage the urban forests in Malaysia

TL;DR: In this paper, a sustainability initiative to inventory the tree species on the campus and assess their total carbon sequestration potential (CSP) is presented, which 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.
Abstract: 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 13986 tons The results also reveal that Ficus benjamina was the predominant species on the campus with CSP equivalent to 3053 tons, followed by Alstonia scholaris with carbon storage of 1638 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

TL;DR: In this article, the tree cover and their potential to store carbon in two cities (Johor Bahru and Pasir Gudang) that are developing rapidly in the south of Peninsular Malaysia have been estimated.
Abstract: Urban trees provide a wide range of ecosystem services that can address climate-change mitigation and adaptation. In this study, the tree cover and their potential to store carbon in two cities (Johor Bahru and Pasir Gudang) that are developing rapidly in the south of Peninsular Malaysia have been estimated. Tree coverage was mapped using Landsat 8 Thematic Mapper satellite data for year 2016. Various digital image processing techniques namely Maximum Likelihood and a sub-pixel classification were applied to obtain tree coverage of urban trees/forest, mangrove and oil palm. Results of the study show that natural tree coverage (forest and mangrove) in the cities range between 19 % and 47 % and generally Pasir Gudang has more tree coverage compared to Johor Bahru. Johor Bahru is the centre for various business and cultural activities, thus more built up areas are found in the city. On average, trees in the cities store approximately 796,136 t carbon or 2,919,164 t CO2-eq which is about 18 % of the total CO2–equivalent emissions projected for 2025 under the Business as Usual (BaU) scenario. The mapping of tree canopy cover and estimating their potential to store carbon is important for assessing climate change mitigation.

TL;DR: In this article, the authors focused on estimating mango wood logs volume both by destructive and non-destructive methods in ICAR-Central Institute of Subtropical Horticulture, Lucknow.
Abstract: Terrestrial carbon sequestration is a natural process towards carbon mitigation in which perennial trees play a vital role. Total biomass of the tree can be measured by a destructive and Non-destructive method. Since tree felling is ban in India, Non-destructive measurements by allometric equations have been widely used for the estimation of tree biomass, which is derived from the destructive method. The present study focused on estimating mango (Mangifera indica) wood logs volume both by destructive and Non-destructive methods in ICAR-Central Institute of Subtropical Horticulture, Lucknow. In Non-destructive method, all required physical parameters were recorded from different positions and further calculated by T2: log formula = ?h (r12+r22+r1 r2)/3; T3: cylindrical shape formula = ?r2h with mean value and T4: cylindrical shape formula = ?r2h with maximum value. The calculated volume of mango wood logs was compared with the obtained volume by T1:Water displacement method. ANOVA was used to compare volume generated from several methods. The results showed that average volume obtained by T2 and T3 methods was found less than the T1 method, which was 13.69 % and 12.95 %, respectively. The volume obtained by T4 was found close to the T1. The study minimized the error while estimating the biomass of mango trees with the essential parameter, the wood volume. Calculating the volume of major branches in the mango tree will make it easier to calculate accurate AGB by a Non-destructive method. The estimated AGB will be helpful to calculate the amount of sequestered carbon and contribution toward mitigating atmospheric carbon dioxide by mango cultivated areas.

TL;DR: In this paper, a review of literature data shows that tropical reforestation has the potential to serve as a carbon offset mechanism both above- and belowground for at least 40 to 80 years, and possibly much longer.
Abstract: Approximately half of the tropical biome is in some stage of recovery from past human disturbance, most of which is in secondary forests growing on abandoned agricultural lands and pastures. Reforestation of these abandoned lands, both natural and managed, has been proposed as a means to help offset increasing carbon emissions to the atmosphere. In this paper we discuss the potential of these forests to serve as sinks for atmospheric carbon dioxide in aboveground biomass and soils. A review of literature data shows that aboveground biomass increases at a rate of 6.2 Mg ha -1 yr -1 during the first 20 years of succession, and at a rate of 2.9 Mg ha -1 yr -1 over the first 80 years of regrowth. During the first 20 years of regrowth, forests in wet life zones have the fastest rate of aboveground carbon accumulation with reforestation, followed by dry and moist forests. Soil carbon accumulated at a rate of 0.41 Mg ha -1 yr -1 over a 100-year period, and at faster rates during the first 20 years (1.30 Mg carbon ha -1 yr -1) . Past land use affects the rate of both above- and belowground carbon sequestration. Forests growing on abandoned agricultural land accumulate biomass faster than other past land uses, while soil carbon accumulates faster on sites that were cleared but not developed, and on pasture sites. Our results indicate that tropical reforestation has the potential to serve as a carbon offset mechanism both above- and belowground for at least 40 to 80 years, and possibly much longer. More research is needed to determine the potential for longer-term carbon sequestration for mitigation of atmospheric CO 2 emissions.
