Title: | UNCERTAINTY IN ABOVE-AND BELOW-GROUND CARBON BIOMASS IN MAJOR LAND COVERS IN SOUTHEAST ASIA: IMPLICATIONS FOR BIOMASS CARBON ASSESSMENTS FOR REDD+ INITIATIVES | Authors: | YUEN JIAQI | Keywords: | Carbon, biomass, land-cover change, roots, allometry, Southeast Asia | Issue Date: | 23-Jan-2015 | Citation: | YUEN JIAQI (2015-01-23). UNCERTAINTY IN ABOVE-AND BELOW-GROUND CARBON BIOMASS IN MAJOR LAND COVERS IN SOUTHEAST ASIA: IMPLICATIONS FOR BIOMASS CARBON ASSESSMENTS FOR REDD+ INITIATIVES. ScholarBank@NUS Repository. | Abstract: | The key finding is that carbon outcomes of transitions between many land-covers are highly variable and uncertain due to a strong reliance on published allometric equations, including root:shoot ratios, which may be either (a) not representative of age, seasonal or site conditions, when the equation is a species-specific equation; or (b) not representative of vegetation growing in a specific geographical location, when the equation was determined elsewhere. Insufficient prior research in the tropics of SE Asia on root biomass also precludes accurate quantification of total ecosystem carbon stocks. Additionally, a lack of methodological standardization creates additional uncertainty that prevents accurate assessment of carbon changes following land-cover conversions. New field investigations following accepted protocols are needed to improve carbon biomass estimates. Re-evaluating and standardizing current field methods should be at the heart of current REDD+ debates before remote sensing methods are applied to extrapolate carbon stocks over a larger area. | URI: | http://scholarbank.nus.edu.sg/handle/10635/119808 |
