Nuril Puslit Biologi LIPI 2011
In the 20th century CO2 concentration in the
atmosfphere is around 365 ppm. Without
mitigation CO2 concentration will increase up to
550 ppm in the middle of 21th century
Global air temperature increases 1.4 – 5.8 oC in
the period of 1990 – 2100 (IPCC, 2001).
Impact on vegetation Without mitigation scenario , dieback condition
in tropical forest and savanna will be occurred
in 2080 s.
With mitigation scenario to stabilize CO2
concentration around 750 ppm:, dieback
condition in tropical forest is delayed up to 100
years.
With mitigation scenario to stabilize CO2
concentration around 550 ppm, dieback is
predicted to be occurred in 2230 s.

Particular interest for forest ecosystems is the role it can play in
carbon sequestration: the process of removing carbon dioxide
(CO2) from the atmosphere and storing it in plants that use
sunlight to turn CO2 into biomass and oxygen
Biological diversity can make a significant contribution to
reducing the build-up of greenhouse gases in the atmosphere.
Forest ecosystem can be both sources and sinks of CO2. A
biological diverse tropical forest holds 50 times more carbon per
unit of area than a monoculture plantation.
Thus, the trees in a forest stand form an essential part in the
functioning of the terrestrial biosphere, especially in the carbon
cycle

• Reducing CO2 in the atmosphere is actually absorbing
CO2 through the process of photosyntesis :
• 6CO2 + 12H2O C6H12O6 + 6O2 + 6H2O
• Carbon sequestration: the process of removing carbon
dioxide (CO2) from the atmosphere and storing it in
plants that use sunlight to turn CO2 into biomass and
oxygen

APPROACH OBJECTIVES
This research aims to provide information on
tree characteristics on carbon sequestration
by analyzing the physiological characteristics
related to carbon sequestration (Biomass
accumulation, CO2 absorption, stomatal
conductance, chlorophyll content)
