Carbon sequestration potential of teak plantations in different agro-climatic zones of Southern India, viz. Northern Dry Zone, Northern Transition Zone, and Hilly Zone were studied. Teak plantations belonging to three age gradations viz. 10, 15 and 20 years were considered for the study. Above ground biomass was computed based on volume estimation and wood density after considering three 10 x 10 m plots. Carbon sequestration potential of teak plantations on farmlands differed significantly with respect to agro-climatic zones and age. Teak plantations raised on the farmlands of Northern Transition Zone had significantly higher above ground biomass than that in Northern Dry Zone and Hilly Zone at all the three age-gradations. Consequently, total above ground carbon sequestered was also significantly higher among the teak plantations of the Northern Transition Zone (247.47 t/ ha) than that in Hilly Zone (157.60 t/ha) and NDZ (103.73 t/ha). For obvious reasons total amount of carbon sequestered was significantly higher in 20-year plantations (330.00 t/ha) than in 15-year (108.53 t/ha) and 10-year plantations (70.27 t/ha). Perhaps optimal average annual rainfall of 749 mm and medium black soil in Northern Transition Zone have contributed to the higher biomass in teak. Poor rainfall in Northern Dry Zone (<585 mm) and poor soil conditions (lateritic formations) in Hilly Zone must have contributed to the poorer growth of teak in these zones.

“…(2) Stock-difference method (i) Approach using permanent sampling plot (PSP) data Permanent sampling plot (PSP) data can be used to estimate mean carbon stock per unit land area of each forest type. Kiyono et al 19 estimated the mean carbon stock of four carbon pools (aboveground and belowground biomasses, deadwood, and litter) per unit land area for two main types of forest (evergreen and deciduous) using data from PSPs established by the Ministry of Environment to monitor forests in Cambodia. The study suggests that by multiplying the averaged carbon stock and forest area 9 for the nation's main forest types, reliable forest carbon stock values can be obtained less expensively at the national level.…”

“…Monitoring costs include that for road construction to access forests. Systematic sampling with a sufficient number of plots and frequent updating of averaged carbon stock data is vital for an accurate estimation of CO 2 emissions from forests under pressure of land-use change and forestry activities 19 . Consequently, when the ground-based measurement costs are high, large-scale monitoring may not be feasible.…”

We examined non-destructive methodologies for practicalities in monitoring anthropogenic greenhouse gas (GHG) emissions from tropical dry-land forest under the influence of various forms of human intervention. Spaceborne SAR withstood comparison with Landsat ETM+ in land cover classification of degraded tropical forest. For measurement of carbon stock and GHG flux per unit land area, the gain-loss method requires both growth rate and removal rate of forest carbon stock. However, the latter has rarely been obtained in tropical forest. For the stock-difference method, permanent sampling plot data can be used to estimate mean carbon stock per unit land area of each forest type. For cyclic land use that includes a clear-cutting stage such as slash-and-burn agriculture, chronosequential changes in carbon stock can be predicted by determining the time and spatial-distribution of cleared land. Changes in forest biomass by logging, storm-damage, etc., may be identified by monitoring the presence and diameter of the crowns of overstory trees. We developed five equations containing the parameter for crown diameter for estimating tree biomass. Overstory height can be a parameter for estimating ecosystem carbon stock of various plant communities, and forest height can be measured by airborne and spaceborne sensors, etc. Generic equations containing the parameter for overstory height are available for estimating community biomass of tropical and subtropical forests. PALSAR has an advantage over other remote systems by enabling frequent sensing and semidirect biomass estimation using backscattering coefficients. However, no reasonable remote sensing methods exist for monitoring the amount of carbon loss by forest conversion and logging in forests This paper reports the results obtained in the "Tropical Rain Forest Research Project (Phase II) (Japan International Cooperation Agency); Ministry of Education and Culture,

Forests hold significant potential for carbon sequestration and climate change mitigation.Forest biomass estimation is vital for sustainable forest management, providing critical input data for implementing the United Nations Reducing Emissions from Deforestation and forest Degradation-plus (REDD+) mechanism. This study investigates the total carbon poolsaboveground biomass (AGB), belowground biomass (BGB), forest floor biomass, and soil carbon-using field-based information in the muyong forest management system, which is native to Ifugao in the Philippines. This study reveals that a difference may be observed between the total carbon stock of the private woodlots (muyong) and that of the communal forest (bilid).The results indicate that the bilid forest has trees with small diameter at breast height (DBH) and high tree density in contrast to the muyong, which has trees with high DBH and low tree density.The average carbon stock per unit area is higher in muyong (150.8 tC/ha) than in bilid (126.1 tC/ha). These findings are valuable in determining whether Ifugao's muyong forest system should be included under the REDD+ framework. Human mediation and management helps forests to sequester a greater amount of carbon than they would without human intervention. Implementation of REDD+ should promote Ifugao's ecosystem and biodiversity conservation and agroforestry practices in addition to protecting traditional agricultural practices and livelihoods in relation to rice terraces.
