2002. Carbon sequestration in a coconut chronosequence (Vanuatu, Oceania).
In : 2nd CarboEurope Meeting, Budapest (Hungary), 4-8 March 2002. CarboEurope Cluster
Résumé : Few results are available about carbon balance of tropical terrestrial ecosystems, either for natural or planted areas. Few experiments use chronosequences (time-series) that allow validation of continuous carbon flow measurements through variations of carbon stocks. Chronosequences also take into account the effect of age on the productivity of ecosystems. Among 110 million hectares of perennial tropical plantations, coconut groves represent 11.5. Coconut is a rapid growing and high-yielding (coprah) monocot. Its growth is continuous, notably in areas where climate conditions are fairly constant during the year. Moreover, coconut oil can be used as fuel in diesel engines. These traits make it a good candidate to the " Clean Development Mechanism " of the " Kyoto Protocol ". Our goals are : measure carbon stocks (biomass, soil cores) and their variations (aerial growth, rhizotron, soil cores, litter fall and litter decomposition) along a chronosequence of coconut aged till 20 years-old (one cultivar, one density, 5 ages); measure fluxes (Eddy-correlation), climate, water balance (TDR, sapflow), soil respiration (portable chamber), rhizospheric respiration (trenched-plots); compare the 2 previous methods for cross validation of carbon balance; model gas exchanges and growth as a function of climate and water constraints.
