Report for the German Agency for Technical Cooperation (GTZ) - UMS

Output of step two
Private sector and local government as well as policy makers have an information about the
financial review of the REDD program and its competitiveness with palm oil program
The willingness of local government and private sectors to be involved in REDD program will
be identified.
Research methods will be further developed

Research Proposal 1: CO2 uptake and carbon balance in the tropical rain forest (secondary
forest and forest plantation)
Introduction
The knowledge of the sources and sinks of carbon dioxide (CO2) is not sufficient. Recently,
the estimations of CO2 fluxes in the temperate forests have been begun to appear in
publications. While there are few data in the tropical area where absorption of carbon dioxide
by forests seem to large. Especially, there is no long-term data in Kalimantan. This makes
difficult to estimate CO2 balance in the global scale. Our purpose is estimate CO2 balances
in the secondary forest and plantation forest which occupy relatively large areas in the
tropical regions especially in Kalimantan.
Objectives
The purpose of this research is to conduct the CO2 flux measurements at most through the
several years, and estimate the production by photosynthesis of the growing secondary
forest and plantation forest. The correlation method will be used for estimating CO2
absorption and emission. Recent studies have shown CO2 flux is highly sensitive to ambient
environmental parameters, such as, solar radiation, temperature, humidity, and others.
Therefore, we can understand the structure of photosynthesis of community by clarifying the
relations between CO2 flux and ambient parameters. Another purpose is to present a way to
parameterize the carbon balance in order to understand the role of the factors controlling the
carbon budget of the tropical secondary forest and plantation forest ecosystem.
Methodology CO2 concentration is measured by CO2 analyzer CO2 flux is measured by eddy
correlation method which is a combination of CO2 concentration and vertical velocity
fluctuations. CO2 concentration and vertical wind velocity are measures on the platform over
the canopy layer, using 30-m tower located in tropical secondary forest. Decomposition of
CO2 in the soil is measured by the gas chronometer. Growing rate of biomass, and litterfall is
measured by tree enumeration. Photosynthetic analysis is made to clarify the
ecophysiological process in the growing secondary forest. The platform is also used to
monitor the relevant meteorological conditions; wind speed and direction, temperature and
humidity, precipitation, photon flux density and net radiation, water content, soil temperature,
etc.
Concepts
CO2 is most important global warming compounds. CO2 flux observed above canopy is NEP
(Net Ecosystem Production) which is important for estimating of global warming in tropical
area, where very few data are obtained. Net Primary Production NPP, Gross Primary
Production GPP, Respiration R will be estimated by observed NEP, observed soil respiration,
and measured biomass increment. These ecological parameters of community are related
with meteorological conditions, including heat balance, water cycle and CO2 budget.
Research Proposal 2: Proposal of Carbon stocks in Secondary forest and Plantation forest
Background
Tropical rain forest has played an important role on carbon accumulation throughout of
photosynthetic activity of it diverse species and vegetation. There are various vegetation of
tropical rain forest both naturally and artificially type with different level of carbon gain
capability. However, forest deflation has lead decreasing capacity of its carbon dioxide
absorption. Even though, regeneration has been made through manual as well as
