ABSTRACT
Delon Marthinus (2008). Assessing the Potency of Bromo Tengger Semeru
National Park for Carbon Sequestration Project. Under the supervision of
Dr. Rizaldi Boer, MAgr and Dr. Antonius B. Wijanarto.
The addition of greenhouse gases and aerosols has changed the composition of the
atmosphere. The changes in the atmosphere have likely influenced temperature,
precipitation, storms and sea level (IPCC, 2007), then will give huge impact to
environment and humankind. To mitigate and to adapt the impact, most country in
the world are agree to collaborate and give their commitment to decrease GHG
emission, conducting reforestation/afforestation, and reduce deforestation.
There are a lot of opportunities provided by developed countries for developing
countries to gain additional revenue by conducting mitigation and adaptation
activity. One of the opportunities is carbon trading through reforestation.
Indonesia has huge potency to implement reforestation project. Bromo Tengger
Semeru National Park is one of the potential sites which is has eligible land for
implementing carbon sequestration project is about 1134.5 ha, refer to CDM
mechanism.
The proposed reforestation project activity will reforest the land with Casuarina
junghuhniana and Acacia deccurens. The activity will sequester around of
1.262.648 T CO2e during twenty years, this value shows that Bromo Tengger
Semeru National Park has high potency for carbon sequestration project. Such
activity is nice as a contribution of Indonesia to mitigate and adapt the climate
change impact.

SUMMARY
Climate change is one of the global issue that makes people are aware
recently. Many studies show the effect of climate change, most of the studies
describe the extreme climate event such as flood, drought, and windstorm. To
mitigate and to adapt the impact of climate change, most countries in the world
agree to collaborate and give their commitment to against it. United Nation
Framework Convention on Climate Change (UNFCCC) facilitates the countries to
develop and implement the activities that are related to the climate change
mitigation and adaptation in Kyoto, Japan in 1997 that called the Kyoto Protocol.
One of the mechanism that has been arrange by UNFCCC is
Afforestation/reforestation Clean Development Mechanism (AR-CDM)
Considering the large forest areas that need to be reforested and afforested,
Indonesia needs to promote climate change mitigation mechanism including AR-
CDM and other mechanisms of forest carbon project. Bromo-Tengger-Semeru
National Park (TNBTS) is one of the potential sites that suitable for those
mechanisms. The eligible land for AR-CDM in this site is around of 1134.5 ha
(assessment by using satellite imagery).
Through reforestation activity, by planting Casuarina Junghuhniana and
Acacia Decurrens, this site may sequester GHG around of 1.262.648 T CO2e in
twenty years (the calculation is using approved methodology from UNFCCC).
This value shows that TNBTS is quite potential site for carbon sequestration
project and give opportunity for Indonesia to participate globally in mitigating the
climate change.

I. INTRODUCTION
1.1. Background
Climate change is one of the most pressing and difficult challenges we face
today. Climate change is caused by the greenhouse effect, whereby certain gases
(greenhouse gases, GHG) in the atmosphere entrap radiation from the sun. Human
activities have upset the natural balance of greenhouse gases that is resulting in
rapid change to the global climate.
Many studies show the effect of climate change, most of the studies describe
the extreme climate event such as flood, drought, and windstorm.
Intergovernmental Panel for Climate Change (IPCC) is the world scientific body
that assesses climate change. Based on their study, the most common problems
that are effected by climate change are the increase of global mean surface
temperature and average sea level rise. In the next 100 years, the global mean
surface temperature will increase 1.4 oC – 5.8
oC and sea level will rise 9 cm – 88
cm, those problems will give huge impact to environment and humankind
(Watson, 2001).
To mitigate and to adapt the impact of climate change, most countries in the
world agree to collaborate and give their commitment to decrease GHG emission,
by conducting reforestation/afforestation, and reducing deforestation. United
Nation Framework Convention on Climate Change (UNFCCC) facilitates the
countries to develop and implement the activities that are related to the climate

change mitigation and adaptation in Kyoto, Japan in 1997 that called the Kyoto
Protocol.
Nowadays, The Kyoto Protocol is part of this on-going political and
economic debate. Clearly, global warming has the potential to influencing directly
or indirectly on every sentient being on Earth. Hence, many political leaders,
together with the rest of humanity, are concerned over the likely impacts that
global warming will have on society and the environment as well as the costs and
benefits of coping with this human made threat. The scientific and policy debates
is still being continued.
Indonesia has ratified the UNFCCC through Law No. 6/1994 and No.
17/2004, this confirms Indonesia as a party to Kyoto Protocol of United Nation
Framework Convention on Climate Change, UNFCCC. Following this, several
studies and national committee on climate change have been established to seek
the mitigation potential and participate in Clean Development Mechanism
(CDM), and non Kyoto Mechanism. However, most of these studies refer
specifically to energy sector, and consequently, the source of information and
knowledge about mitigation strategies for LULUCF is still very limited and
general (Kirsfianti, 2003).
Considering the large forest areas that need to be reforested and afforested,
Indonesia needs to promote climate change mitigation mechanism including CDM
and other mechanisms such as forest carbon project. Forest carbon project in
Indonesia can be grouped into three categories. First is conservation and forest
management, includes protection forest, enhanced natural regeneration or
enrichment planting, and reduced impact logging. Second is sinks enhancement

including reforestation, afforestation, timber estate, and agroforestry. Third is the
substitution of fossil fuel-based energy with biomass energy.
It is recommended that tree-based farming systems such as reforestation,
afforestation, timber estate and agroforestry offer a sustainable alternative based
on several aspects: (i) incentives to rehabilitate critical area, (ii) source of
additional income for community, (iii) meet the need of household income for
short, medium, and long term.
Bromo-Tengger-Semeru National Park (TNBTS), is located at 7o54’-8
o13’
South and 112o51’–113
o04’ East. The park lies in four administrative areas; West-
Malang district; East-Probolingo district; North-Pasuruan District and South-
Lumajang District. Based on Minister fo Forestry Decree No. 278/Kpts-VI/1997,
the total of the Bromo-Tengger-Semeru National Park is 50,276 ha (TNBTS,
2007). Large area of this National Park has been degraded and covered by
grassland.
Based on local correspondents, the area was initially covered by ‘cemara
gunung’ (Casuarina junghuhniana) and managed by the Dutch Government. A
small portion of the degraded area at Kandangan Block have been reforested using
government fund (i.e. 30 ha) with Cemara Gunung. Due to the limited funding
and large area of degraded land that need to be reforested, without additional
financial support from other sources, most of this area will remain as grassland.
There are opportunities to gain additional funding from private institution by
implementing Carbon Sequestration Project.

II. LITERATURE REVIEW
2.1. Climate Change
The climate of the Earth is constantly changing. In the past it has altered as
a result of natural causes. Today, however, the term climate change is generally
used when referring to changes in our climate which have been identified since
the early 20th
century. The changes over recent years and prediction over the next
80 years are thought to be a result of human activities rather than natural changes.
In the atmosphere the greenhouse effect is very important when we talk about
climate change as it relates to the gases which keep the Earth warm (IGES, 2005).
The term 'Greenhouse Effect' is commonly used to describe the increase in
the Earth's average temperature that has been recorded over the past 100 years.
However, without the 'natural greenhouse effect', life on Earth would be very
different to that seen today. The 'natural greenhouse effect', the Earth receives its
life sustaining warmth from the Sun. On its way to the Earth's surface most of the
heat energy passes through the Earth's atmosphere, while a smaller proportion is
reflected back into space. The energy warms the Earth's surface, and as the
temperature increases, the Earth radiates heat energy (infrared energy) back into
the atmosphere. As this energy has a different wavelength to that coming from the
sun, some is absorbed by gases in the atmosphere.
There are four main naturally occurring gases that are responsible for the
Greenhouse Effect; water vapour, carbon dioxide, methane and nitrous oxide.
Although most of the greenhouse gases occur naturally in the atmosphere, some
are man-made and the most well-known of these are the fluorocarbons. Since the
industrial revolution, human activities have also resulted in an increase in natural
greenhouse gases, especially carbon dioxide. An increase in these gases in the
atmosphere enhances the atmosphere's ability to trap heat, which leads to an
increase in the average surface temperature of the Earth (IGES, 2005).

Figure 2.1. Greenhouse effect.
If the increasing of GHG emission still continues, then in the next 100 years
the seriously climate change impact will occur, the global mean surface
temperature will increase 1.4 oC – 5.8
oC and sea level will rise 9 Cm – 88 Cm,
while the human population is increasing time to time, those problems will give
huge impact to humankind and other species (Watson, 2001). Most of GHG
emission comes from developed countries.
The need to control climate change by reducing the world’s emissions of
greenhouse gases is now accepted throughout the international community. One of
the toughest problems in getting an international agreement to do so has been how
to share the responsibility between the developed and developing world.
2.2. Kyoto Protocol.
The Kyoto Protocol was drawn up in 1997 and came into force in February
2005. The protocol requires that by the period 2008-2012 a group of 40 developed
countries will have reduced their greenhouse gas emissions by five percent below
their 1990 levels. While the Protocol commits the developing countries to adopt
Chapter 2 – Literature Review
7
appropriate policies to control their emissions, those countries are not committed
to specific emissions targets.
The Protocol hands most of the responsibility for reducing emissions to the
developed countries, but reductions anywhere in the world will ultimately have
the same effect on the atmosphere and threats of global warming. Moreover some
developed countries might find it easier and more cost effective to support
emissions reductions in other developed or developing countries rather than at
home.
Therefore the Kyoto Protocol includes three mechanisms to introduce
flexibility to the developed countries’ approach and allowing them to make the
most cost-effective emissions reductions without softening their commitment to
the Protocol’s overall goals (UNFCCC, 1998).
2.2.1. Clean Development Mechanism (CDM)
CDM is one of the flexible mechanisms contained in the Kyoto Protocol.
Through CDM, developing countries may be able to actively participate in
helping developed countries obligated to decrease the emission of green house
gas, by doing investment in developing countries in various sectors, while the
developing countries benefit in reaching continuous development objective as the
national agenda besides reaching the main objective to stabilize the emission of
green house gas in handling the effect of global warming. Some CDM sectors to
be implemented is CDM in the sectors of energy, transportation, household,
garbage and forestry. Forestry sector CDM is a different mechanism to CDM of
other sectors since the emission decrease is conducted by carbon absorption in the
atmosphere by trees (carbon sequestration) while other sectors apply emission
decrease at the source of emission.
The activities to be proposed for forestry sector CDM are limited only for
afforestation and reforestation activities, known as AR-CDM. Afforestation is the
re-planting on land cleared since 50 years ago while reforestation is the re-
planting of land which is clear of trees before the year 1990. The stages or
procedures of forestry CDM activities, known as forestry CDM project cycle,
begin with project identification activity, project designing, project design
Chapter 2 – Literature Review
8
documentation, agreement by the CDM National Commission, validation,
registration, implementation and monitoring, verification and certification, and
finally, the issuing of CER (Certified Emission Reduction) by the CDM Board of
Executors. The stage of project designing is the most important stage for the
success of the CDM project since good analysis on accurate project designing,
including methodology and the involvement of related stakeholders, is necessary.
This is intended to produce projects which can sufficiently benefit from CDM,
including sufficient funding provision in order that the transaction cost does not
exceed the available fund.
2.2.2. Joint Implementation (JI)
The second Kyoto Mechanism provides for one developed country helping
another developed country, usually part of the former USSR, to implement
specific projects with low levels of emissions, either to replace or upgrade an
existing high-emission facility or to adjust the design of a new project so as to
lower its expected emissions. 126 project JI proposals were submitted by March
2008.
Two early examples will change from a wet to a dry process at a Ukraine
cement works, reducing energy consumption by 53 percent by 2008-2012; and
rehabilitate a Bulgarian hydropower project, with a 267,000 ton reduction of CO2
equivalent during 2008-2012 (Lightfoot, 2008).
In both these cases including the expected value of the emission reduction
units in the investment analysis made the projects financially viable.
2.2.3. Emission Trading.
The Third mechanism is emissions trading. The Kyoto Protocol provides for
developed countries to buy emissions reduction units if they cannot otherwise
meet their emissions targets, and to sell them if they expect to exceed their targets.
This enables countries for which reducing emissions levels is expensive to buy
emission reduction units from countries where costs are lower, thus lowering the
overall costs of reducing emissions.
Chapter 2 – Literature Review
9
Transfers and acquisitions of these units are tracked and recorded through
national registry systems. Trading is also open to companies or other non-
governmental organizations under the supervision of their respective countries.
2.2.4. Other mechanisms
Voluntary Basis, a number of other voluntary standards exist.
ISO 14064
This standard operates under the ISO family of standards and is a guideline-
based system of reporting. Its major components are: 1) Project Reporting:
guiding project proponents quantification, monitoring and reporting of greenhouse
gas emissions reductions (ISO 14064 Part 2); and 2) Validation and Verification:
guiding the validation and verification of greenhouse gas assertions from
organizations or projects (ISO 14064 Part 3), Wintergreen, 2007.
Plan Vivo
Plan Vivo is specifically designed for community-based agro forestry
projects. It calls itself “a system for promoting sustainable livelihoods in rural
communities, through the creation of verifiable carbon credits. Although Plan
Vivo projects have been executed successfully in the past, the transactions costs to
verify and monitor this project appear to be prohibitively high for mid-small scale
projects, and the standard has not yet won wide recognition as an industry
standard.
VER + Standard
TÜV SÜD launched the VER+ Standard to certify carbon neutrality and
credits from voluntary carbon offset projects. Although based on CDM and JI
methodology to be “streamlined” with Kyoto, VER+ is fungible on the voluntary
market and compatible with CCX and the Voluntary Carbon Standard. Despite its
ostensible quality, this standard will most likely preclude the use of other
verifiers, likely available at a lower cost in Indonesia. While the chosen voluntary
method will most likely not restrict the options for certification through VER + at
Chapter 2 – Literature Review
10
a later date, other certifications appear to offer more suitable methodologies
(Kollmuss, et al).
The Voluntary Carbon Standard (VCS)
Voluntary Carbon Standard’s “Version 1 for Consultation” has been
publicly available sine March 2006, and the Climate Group, the International
Emissions Trading Association (IETA) and the World Economic Forum jointly
launched the final version of VCS in 2007. The VCS aims “to provide a credible
but simple set of criteria that will provide integrity to the voluntary carbon market
and underpin the credible actions that already exist.” Mark Kenber, Policy
Director at the Climate Group, described the standard as creating a basic “quality
threshold” in the market. A goal for the VCS is for it to co-exist with other stan-
dards and “reinforce those that are robust and already exist (e.g. WBCSD/WRI
GHG Protocol for Project Accounting, Gold Standard, and CCX). Credits
certified via the VCS are then called Voluntary Carbon Units (VCUs). The 2007
program guidelines include ISO 14064-2:2006, ISO 14064-3:2006, ISO
14065:2007.
The VCS was rated as one of the most promising standards to handle a
significant volume of voluntary carbon trades by Ecosystem Marketplace. VCS
certified projects are intended to be as robust as those under the Kyoto Protocol’s
Clean Development Mechanism (CDM) but they reduce participants’ transaction
costs through added flexibility during the certification, verification and
monitoring process. It has come under intense scrutiny from some groups, most
notably WWF, which allege that the standard will not screen-out low quality
projects and may thereby undermine market credibility. It is unclear if this
standard will live up to its initial potential (Voluntary Carbon Standard, 2007).
Climate, Community and Biodiversity Alliance, CCBA
These Climate, Community and Biodiversity Project Design Standards (the
“CCB Standards”) identify land-based projects that can simultaneously deliver
compelling climate, biodiversity and community benefits. The CCB Standards are
primarily designed for climate change mitigation projects. The CCB Standards
Chapter 2 – Literature Review
11
were developed by the Climate, Community & Biodiversity Alliance (CCBA).
The CCBA is a global partnership of research institutions, corporations and
environmental groups, with a mission to develop and promote voluntary standards
for multiple-benefit land-use projects.
The CCBA standard offers credible set of criteria to create a premium
carbon project with potential for high social and ecological benefits. The standard
has been well received on the voluntary market since its launch in May 2005. It
was created by a consortium of research institutions, corporations and
environmental groups to develop a credible, comprehensive standard with that
delivers sustainable benefits in emerging economies using both public and private
financing. It is one of the informal ‘best-practice’ methodologies emerging in the
voluntary sector among independently verified standards. More information on
this standard is available at http://www.climate-standards.org/
From all of the mechanism mentioned above, CDM mechanism is the most
applicable mechanism, the methods that have been approved by UNFCCC
(United Nation Frameworks for Climate Change Convention) regarding CDM
mechanism have been adopted by other mechanism. Therefore, the method and
analysis in this study are refer to AR-CDM mechanism
2.3. Terms in AR-CDM project
2.3.1. Additionality
The activity or project under CDM mechanism should be “additional”. It
means that without CDM mechanism the activity or project will not be successful
in sequestering the GHG. There is a tool that prided by UNFCCC to testing
whether the activity or project is additional on not additional, “Tool for the
Demonstration and Assessment of Additionality in A/R CDM Project
Activities (Version 02)”. The document is available at
hppt://cdm.unfccc/int/methodologies/ARmethodologies/approved_ar.html.
The procedure of this tool are (Figure 2.2);
Step 0. Preliminary screening based on the starting date of the A/R project
activity. If the afforestation or reforestation CDM project activity has a starting
Chapter 2 – Literature Review
12
date after 31 December 1999 but before the date of its registration, then the
project participants shall:
• Provide evidence that the starting date of the A/R CDM project activity
was after 31 December 1999; and
• Provide evidence that the incentive from the planned sale of CERs was
seriously considered in the decision to proceed with the project activity.
This evidence shall be based on (preferably official, legal and/or other
corporate) documentation that was available to third parties at, or prior
to, the start of the project activity.
Step 1. Identification of alternative land use scenarios to the proposed A/R
CDM project activity. This step serves to identify alternative land use scenarios to
the proposed CDM project activity(s) that could be the baseline scenario, through
the following sub-steps: Sub-step 1a. Identify credible alternative land use
scenarios to the proposed CDM project activity, identify realistic and credible
land-use scenarios that would have occurred on the land within the proposed
project boundary in the absence of the afforestation or reforestation project
activity under the CDM3. The scenarios should be feasible for the project
participants or similar project developers taking into account relevant national
and/or sectoral policies4 and circumstances, such as historical land uses, practices
and economic trends. The identified land use scenarios shall at least include:
• Continuation of the pre-project land use;
• Afforestation / reforestation of the land within the project boundary performed
without being registered as the A/R CDM project activity;
• If applicable, forestation of at least a part of the land within the project
boundary of the proposed A/R CDM project at a rate resulting from: Legal
requirements; or extrapolation of observed forestation activities in the
geographical area with similar socioeconomic and ecological conditions to the
proposed A/R CDM project activity occurring in a period since 31 December
1989.
For identifying the realistic and credible land-use scenarios; land use
records, field surveys, data and feedback from stakeholders, and information from
Chapter 2 – Literature Review
13
other appropriate sources, including Participatory rural appraisal (PRA) may be
used as appropriate.
All identified land use scenarios must be credible. All land-uses within the
boundary of the proposed A/R CDM project activity that are currently existing or
that existed at some time since 31 December 1989 but no longer exist, may be
deemed realistic and credible. For all other land use scenarios, credibility shall be
justified. The justification shall include elements of spatial planning information
(if applicable) or legal requirements and may include assessment of economical
feasibility of the proposed land use scenario.
Outcome of Sub-step 1a: List of credible alternative land use scenarios that
would have occurred on the land within the project boundary of the A/R CDM
project activity.
Sub-step 1b. Consistency of credible land use scenarios with enforced
mandatory applicable laws and regulations (This sub-step does not consider
national and local policies that do not have legally-binding status and local
policies that have been implemented since the adoption by the COP of the CDM
M&P [decision 17/CP.7, 11 November 2001]).
Apply the following procedure:
• Demonstrate that all land use scenarios identified in the sub-step 1a: are in
compliance with all mandatory applicable legal and regulatory requirements;
• If an alternative does not comply with all mandatory applicable legislation and
regulations then show that, based on an examination of current practice in the
region in which the mandatory law or regulation applies, those applicable
mandatory legal or regulatory requirements are systematically not enforced
and that non-compliance with those requirements is widespread, i.e. prevalent
on at least 30% of the area of the smallest administrative unit that
encompasses the project area;
• Remove from the land use scenarios identified in the sub-step 1a, any land use
scenarios which are not in compliance with applicable mandatory laws and
regulations unless it can be shown these land use scenarios result from
systematic lack of enforcement of applicable laws and regulations.
Chapter 2 – Literature Review
14
Outcome of Sub-step 1b: List of plausible alternative land use scenarios to the
A/R CDM project activity that are in compliance with mandatory legislation and
regulations taking into account the their enforcement in the region or country and
EB decisions on national and/or sectoral policies and regulations. If the list
resulting from the Sub-step 1b is empty or contains only one land use scenario,
than the proposed A/R CDM project activity is not additional.
Sub-step 1c. Selection of the baseline scenario: The baseline methodology
that would use this tool shall provide for a stepwise approach justifying the
selection and determination of the most plausible baseline scenario.
→ Proceed to Step 2 (Investment analysis) or Step 3 (Barrier analysis), as it is
necessary to undertake at least one of them.
Step 2. Investment analysis. Determine whether the proposed project activity,
without the revenue from the sale of temporary CERs (tCERs) or long-term CERs
(lCERs), is economically or financially less attractive than at least one of the other
land use scenarios. Investment analysis may be performed as a stand-alone
additionality analysis or in connection to the Barrier analysis (Step 3). To conduct
the investment analysis, use the following sub-steps:
Sub-step 2a. Determine appropriate analysis method. Determine whether to apply
simple cost analysis, investment comparison analysis or benchmark analysis (sub-
step 2b). If the A/R CDM project activity generates no financial or economic
benefits other than CDM related income, then apply the simple cost analysis
(Option I). Otherwise, use the investment comparison analysis (Option II) or the
benchmark analysis (Option III). Note, that Options I, II and III are mutually
exclusive hence, only one of them can be applied.
Sub-step 2b. – Option I. Apply simple cost analysis. Document the costs
associated with the A/R CDM project activity and demonstrate that the activity
produces no financial benefits other than CDM related income. If the land within
the boundary of the proposed of the A/R CDM project activity was at least
partially forested since 31 December 1989 and the land is not a forest at the
project start, the project participants shall identify incentives/reasons/actions that
allowed for the past forestation and demonstrate that the current legal/financial or
other applicable regulations or socio-economical or ecological or other local
Chapter 2 – Literature Review
15
conditions have changed to an extent that justifies the conclusion that the activity
produces no financial benefits other than CDM related income.
→ If it is concluded that the proposed A/R CDM project activity produces no
financial benefits other than CDM related income then proceed to Step 4
(Common practice analysis).
Sub-step 2b. – Option II. Apply investment comparison analysis. Identify the
financial indicator, such as IRR8, NPV, payback period, cost benefit ratio most
suitable for the project type and decision-making context.
Sub-step 2b – Option III. Apply benchmark analysis. Identify the financial
indicator, such as IRR9, NPV, payback period, cost benefit ratio, or other (e.g.
required rate of return (RRR) related to investments in agriculture or forestry,
bank deposit interest rate corrected for risk inherent to the project or the
opportunity costs of land, such as any expected income from land speculation)
most suitable for the project type and decision context. Identify the relevant
benchmark value, such as the required rate of return (RRR) on equity. The
benchmark is to represent standard returns in the market, considering the specific
risk of the project type, but not linked to the subjective profitability expectation or
risk profile of a particular project developer. Benchmarks can be derived from:
• Government bond rates, increased by a suitable risk premium to reflect private
investment and/or the project type, as substantiated by an independent
(financial) expert;
• Estimates of the cost of financing and required return on capital (e.g.
commercial lending rates and guarantees required for the country and the type
of project activity concerned), based on bankers views and private equity
investors/funds’ required return on comparable projects;
• A company internal benchmark (weighted average capital cost of the
company) if there is only one potential project developer (e.g. when the
proposed project land is owned or otherwise controlled by a single entity,
physical person or a company, who is also the project developer). The project
developers shall demonstrate that this benchmark has been consistently used
in the past, i.e. that project activities under similar conditions developed by
the same company used the same benchmark.

Sub-step 2c. Calculation and comparison of financial indicators (only
applicable to options II and III): Calculate the suitable financial indicator for the
proposed A/R CDM project activity without the financial benefits from the CDM
and, in the case of Option II above, for the other land use scenarios. Include all
relevant costs (including, for example, the investment cost, the operations and
maintenance costs), and revenues (excluding tCER or lCERs revenues, but
including subsidies/fiscal incentives where applicable), and, as appropriate, non-
market cost and benefits in the case of public investors.
Present the investment analysis in a transparent manner and provide all the
relevant assumptions in the CDM-AR-PDD, so that a reader can reproduce the
analysis and obtain the same results. Clearly present critical economic parameters
and assumptions (such as capital costs, lifetimes, and discount rate or cost of
capital). Justify and/or cite assumptions in a manner that can be validated by the
DOE. In calculating the financial indicator, the project’s risks can be included
through the cash flow pattern, subject to project-specific expectations and
assumptions (e.g. insurance premiums can be used in the calculation to reflect
specific risk equivalents).
Assumptions and input data for the investment analysis shall not differ across
the project activity and its alternatives, unless differences can be well
substantiated. Present in the AR-CDM-PDD submitted for validation a clear
comparison of the financial indicator for the proposed A/R CDM project activity
without the financial benefits from the CDM and:
Option II (investment comparison analysis): If one of the other land use
scenarios has the better indicator (e.g. higher IRR), then the A/R CDM project
activity can not be considered as the financially attractive; or
Option III (benchmark analysis): If the A/R CDM project activity has a less
favourable indicator (e.g. lower IRR) than the benchmark, then the A/R CDM
project activity cannot be considered as financially attractive.
→ If it is concluded that the proposed A/R CDM project activity without the
financial benefits from the CDM is not financially most attractive then proceed to
Step 2d (Sensitivity Analysis).
Chapter 2 – Literature Review
17
Sub-step 2d. Sensitivity analysis. Include a sensitivity analysis that shows
whether the conclusion regarding the financial attractiveness is robust to
reasonable variations in the critical assumptions. The investment analysis provides
a valid argument in favour of additionality only if it consistently supports (for a
realistic range of assumptions) the conclusion that the proposed A/R CDM project
activity without the financial benefits from the CDM is unlikely to be financially
attractive. If the land within the boundary of the proposed A/R CDM project
activity was at least partially forested since 31 December 1989 and the land is not
a forest at the project start, the project participants shall demonstrate that
incentives/reasons/actions that allowed for the past forestation have changed to an
extent that affects the financial attractiveness of forestation of the project area
without being registered as the A/R CDM project.
• If after the sensitivity analysis it is concluded that the proposed A/R CDM
project activity without the financial benefits from the CDM is unlikely to be
financially most attractive (Option II and Option III), then proceed directly to
Step 4 (Common practice analysis).
• If after the sensitivity analysis it is concluded that the proposed A/R CDM
project activity is likely to be financially most attractive (Option II and Option
III), then the project activity cannot be considered additional by means of
financial analysis. Optionally proceed to Step 3 (Barrier analysis) to prove that
the proposed project activity faces barriers that do not prevent the baseline
land use scenario(s) from occurring. If the Step 3 (Barrier analysis) is not
employed then the project activity cannot be considered additional.
Step 3. Barrier analysis. Barrier analysis may be performed as a stand-alone
additionality analysis or as an extension of investment analysis. If this step is
used, determine whether the proposed project activity faces barriers that:
• Prevent the implementation of this type of proposed project activity; and
• Do not prevent the implementation of at least one of the alternative land use
scenarios.
Use the following sub-steps:
Sub-step 3a. Identify barriers that would prevent the implementation of type of the
proposed project activity: Establish that there are barriers that would prevent the
Chapter 2 – Literature Review
18
implementation of the type of proposed project activity from being carried out if
the project activity was not registered as an A/R CDM activity. The barriers
should not be specific to the project participants. Such barriers may include,
among others:
• Investment barriers, other than the economic/financial barriers in Step 2
above, inter alia:
o For A/R project activities undertaken and operated by private entities:
Similar activities have only been implemented with grants or other non-
commercial finance terms. In this context similar activities are defined as
activities of a similar scale that take place in a comparable environment
with respect to regulatory framework and are undertaken in the relevant
geographical area;
o Debt funding is not available for this type of project activity;
o No access to international capital markets due to real or perceived risks
associated with domestic or foreign direct investment in the country where
the project activity is to be implemented, as demonstrated by the credit
rating of the country or other country investment reports of reputed origin;
o Lack of access to credit.
• Institutional barriers, inter alia:
o Risk related to changes in government policies or laws;
o Lack of enforcement of forest or land-use-related legislation.
• Technological barriers, inter alia:
o Lack of access to planting materials;
o Lack of infrastructure for implementation of the technology.
• Barriers related to local tradition, inter alia:
o Traditional knowledge or lack thereof, laws and customs, market
conditions, practices;
o Traditional equipment and technology.
• Barriers due to prevailing practice, inter alia:
o The project activity is the “first of its kind”: No project activity of this
type is currently operational in the host country or region.
• Barriers due to local ecological conditions, inter alia:
Chapter 2 – Literature Review
19
o Degraded soil (e.g. water/wind erosion, salination, etc.);
o Catastrophic natural and / or human-induced events (e.g. land slides,
fire, etc);
o Unfavourable meteorological conditions (e.g. early/late frost, drought);
o Pervasive opportunistic species preventing regeneration of trees (e.g.
grasses, weeds);
o Unfavourable course of ecological succession;
o Biotic pressure in terms of grazing, fodder collection, etc.
• Barriers due to social conditions, inter alia:
o Demographic pressure on the land (e.g. increased demand on land due
to population growth);
o Social conflict among interest groups in the region where the project
takes place;
o Widespread illegal practices (e.g. illegal grazing, non-timber product
extraction and tree felling);
o Lack of skilled and/or properly trained labour force;
• Lack of organisation of local communities;
• Barriers relating to land tenure, ownership, inheritance, and property rights, inter
alia:
o Communal land ownership with a hierarchy of rights for different
stakeholders limits the incentives to undertake A/R activity;
o Lack of suitable land tenure legislation and regulation to support the
security of tenure;
o Absence of clearly defined and regulated property rights in relation to
natural resource products and services;
o Formal and informal tenure systems that increase the risks of
fragmentation of land holdings;
o Barriers relating to markets, transport and storage;
o Unregulated and informal markets for timber, non-timber products and
services prevent the transmission of effective information to project
participants;
Chapter 2 – Literature Review
20
o Remoteness of A/R activities and undeveloped road and infrastructure
incur large transportation expenditures, thus eroding the
competitiveness and profitability of timber and non-timber products
from the CDM activity;
o Possibilities of large price risk due to the fluctuations in the prices of
timber and non timber products over the project period in the absence
of efficient markets and insurance mechanisms;
o Absence of facilities to convert, store and add value to production
from CDM activities limits the possibilities to capture rents from the
land use under A/R CDM project activity.
The identified barriers are only sufficient grounds for demonstration of
additionality if they would prevent potential project participants from carrying out
the proposed project activity if it was not expected to be registered as an A/R
CDM project activity. Provide transparent and documented evidence, and offer
conservative interpretations of this documented evidence, as to how it
demonstrates the existence and significance of the identified barriers. Anecdotal
evidence can be included, but alone is not sufficient proof of barriers. The type of
evidence to be provided may include:
• Relevant legislation, regulatory information or environmental/natural
resource management norms, acts or rules;
• Relevant (sectoral) studies or surveys (e.g. market surveys, technology
studies, etc) undertaken by universities, research institutions,
associations, companies, bilateral/multilateral institutions, etc;
• Relevant statistical data from national or international statistics;
• Documentation of relevant market data (e.g. market prices, tariffs,
rules);
• Written documentation from the company or institution developing or
implementing the A/R CDM project activity or the A/R CDM project
developer, such as minutes from Board meetings, correspondence,
feasibility studies, financial or budgetary information, etc;
Chapter 2 – Literature Review
21
• Documents prepared by the project developer, contractors or project
partners in the context of the proposed project activity or similar
previous project implementations;
• Written documentation of independent expert judgements from
agriculture, forestry and other land-use related Government / Non-
Government bodies or individual experts, educational institutions (e.g.
universities, technical schools, training centres), professional
associations and others.
If the land within the boundary of the proposed of the A/R CDM project
activity was at least partially forested since 31 December 1989 and the land is not
a forest at the project start, the project participants shall identify,
incentives/reasons/actions/that allowed for the past forestation and shall
demonstrate that the current legal/financial or other applicable regulations or
ecological or other local conditions have changed to the extent that they pose a
barrier which allows for conclusion that repetition of the forestation performed
without being registered as the A/R CDM project activity is not possible.
Sub-step 3 b. Show that the identified barriers would not prevent the
implementation of at least one of the alternative land use scenarios (except the
proposed project activity): If the identified barriers also affect other land use
scenarios, explain how they are affected less strongly than they affect the
proposed A/R CDM project activity. In other words, explain how the identified
barriers are not preventing the implementation of at least one of the alternative
land use scenarios. Any land use scenario that would be prevented by the barriers
identified in Sub-step 3a is not a viable alternative, and shall be eliminated from
consideration. At least one viable land use scenario shall be identified.
• If both Sub-steps 3a – 3b are satisfied, then proceed directly to Step 4
(Common practice analysis).
• If one of the Sub-steps 3a – 3b is not satisfied then the project activity cannot
be considered additional by means of barrier analysis. Optionally proceed to
Step 2 (Investment analysis) to prove that the proposed A/R CDM project
activity without the financial benefits from the CDM is unlikely to produce
economic benefit (Option I) or to be financially attractive (Option II and
Chapter 2 – Literature Review
22
Option III). If the Step 2 (Investment analysis) is not employed then the
project activity cannot be considered additional.
Step 4. Common practice analysis. The previous steps shall be
complemented with an analysis of the extent to which similar forestation activities
have already diffused in the geographical area of the proposed A/R CDM project
activity. This test is a credibility check to demonstrate additionality that
complements the barrier analysis (Step 2) and the investment analysis (Step 3).
Provide an analysis to which extent similar forestation activities to the one
proposed as the A/R CDM project activity have been implemented previously or
are currently underway. Similar forestation activities are defined as that which are
of similar scale, take place in a comparable environment, inter alia, with respect
to the regulatory framework and are undertaken in the relevant geographical area,
subject to further guidance by the underlying methodology. Other registered A/R
CDM project activities shall not to be included in this analysis. Provide
documented evidence and, where relevant, quantitative information. Limit your
considerations to the period since 31 December 1989.
If forestation activities similar to the proposed A/R CDM project activity are
identified, then compare the proposed project activity to the other similar
forestation activities and assess whether there are essential distinctions between
them. Essential distinctions may include a fundamental and verifiable change in
circumstances under which the proposed A/R CDM project activity will be
implemented when compared to circumstances under which similar forestations
were carried out. For example, barriers may exist, or promotional policies may
have ended. If certain benefits rendered the similar forestation activities
financially attractive (e.g., subsidies or other financial flows), explain why the
proposed A/R CDM project activity cannot use the benefits. If applicable, explain
why the similar forestation activities did not face barriers to which the proposed
A/R CDM project activity is subject.
→ If Step 4 is satisfied, i.e. similar activities can be observed and essential
distinctions between the proposed CDM project activity and similar activities
cannot be made, then the proposed CDM project activity cannot be considered
Chapter 2 – Literature Review
23
additional. Otherwise, the proposed A/R CDM project activity is not the baseline
scenario and, hence, it is additional.
Figure 2.2. Indicative flowchart of the tool for the demonstration and assessment of
additionality in A/R CDM project activities
2.3.2. Baseline
As stated above, CDM afforestation and reforestation projects enhance
greenhouse gas removals in one country to permit an equivalent quantity of
Chapter 2 – Literature Review
24
greenhouse gas emissions in another country, without changing the global
emission balance. Technically, the CDM is a baseline-and-credit trade
mechanism, not a cap-and-trade mechanism. Therefore, enhancements of
removals by afforestation and reforestation projects must create real, measurable
and long-term benefits related to the mitigation of climate change (Kyoto
Protocol, Article 12.5b), and must be additional to any that would occur in the
absence of the certified project activity (Kyoto Protocol, Article 12.5c). The “in
the absence” scenario is also referred to as the baseline scenario.
The Marrakech Accords define a baseline scenario as one that “reasonably
represents greenhouse gas emissions that would occur in the absence of the
proposed project activity” and is derived using an approved baseline method. The
Marrackech Accords also state that the project baseline shall be established “in a
transparent and conservative manner regarding the choices of approaches,
assumptions” and that it shall be established “on a project-specific basis”. In
summary, the baseline is the most likely course of action and development over
time, in the absence of CDM financing.
The Figure 2.3 shows the time-path of carbon stocks in the project and
baseline scenarios.

2.3.3. Leakage
Some projects will be successful in sequestering more carbon within the
project area, but the project activities may change activities or behaviours
elsewhere. These changes may lead to reduced sequestration or increased
emissions outside the project boundary, negating some of the benefits of the
project. This is called leakage. A simple example is a project that reforests an area
of poor quality grazing land, but leads to the owners of the displaced livestock to
clear land outside the project boundaries to establish new pastures. The types of
activities that might result in leakage vary with the type of projects, but both
LULUCF and non-LULUCF projects are subject to leakage (Pearson, 2005).
2.3.4. Permanence
During the negotiations leading up to the Kyoto Protocol and subsequently,
there was considerable concern that credits issued for carbon sequestration would
be subject to a risk of re-emission, due to either human action or natural events
such as wildfires. This was called the permanence risk and it is unique to
LULUCF projects under the Protocol. Eventually, Parties agreed that credits aris-
ing from CDM afforestation and reforestation projects should be temporary, but
could be re-issued or renewed every five years after an independent verification to
confirm sufficient carbon was still sequestered within the project to account for all
credits issued.
This deals effectively with the permanence risk and guarantees that any
losses of sequestered carbon for which credits have been issued will have to be
made up through either additional sequestration elsewhere or through credits
derived from non-LULUCF activities. Two types of temporary credits were
agreed: temporary CERs and long-term CERs.
2.4. Remote Sensing in Forestry
There have been many techniques to detect land change developed by many
scientists. For instant spectral mixture analysis, Li-Strahler canopy model, Chi-
Square transformation, artificial neural network, and also from the integration of
several data source.
Chapter 2 – Literature Review
26
D.lu in his paper summarizes 7 methods that have been used to implement
land change detection;
1) Algebra, in this category contain of image difference, image regression,
image comparison, vegetation index difference, change vector analysis, and
background subtraction. This algorithm has specific character, that character is
threshold selection to detect the changing area. This method relatively not
complicated and simple to be implemented, but unfortunately the change matrix
can not be defined.
2) Transformation, the methods that included in this category are Principal
component analysis (PCA), Gramm-Schmidt (G), and Chi-square transformation.
The advantages of this method are in terms of decreasing redundancy among
bands, and gives fine information on changed area though not to clearly. The
disadvantages are the difficulties on interpretation process and labeling the change
information on the image that have transformed.
3) Classification, this category contain of post classification comparison,
spectral-temporal combination analysis, unsupervised change detection, hybrid
change detection, and ANN. This method based on the image classification, where
the quantity and quality of sample is very crucial to produce a good classification
result. The advantages from this method are able to provide matrix of change and
minimize the external impact such as atmosphere on multy-temporal image.
4) Advance model, model that include in this category are Li-Strahler
reflectance model, spectral mixture model, and biophysical parameter estimation. In
this method, the reflectance value of image is converted into physical parameter
through linear or nonlinear model. The converted parameter is usable to extract the
information from vegetation. The disadvantages of this method are time consuming
and complicated process on the development of model could convert reflectance
value to biophysical parameter.
5) GIS (Geographic Information System), this category contain of integrated
GIS and remote sensing application, and purely GIS only. The advantages of this
method are, all of the data from different source that represent land changes are
provided by this method. In the other hand, the mixing data process from different
source is influenced by accuracy of each data.
Chapter 2 – Literature Review
27
6) Visual analysis, this category contain of image visual interpretation and on-
screen digitizing of the changed area. This method is applicable to be used by
scientist and people who have long experience. Texture, shape, form, size and pattern
of the image are key element that used for detection of land cover change. Scientist
uses these entire elements to help him on land cover change analysis.
7) Other land change detection technique, as addition from six category
above, there are few method that exist but not able to be putted on the category above,
such as the use of spatial dependent measurement on TM imagery to detect changes
in savanna, the use of knowledge based vision system to detect land cover change on
the urban edge, the use of vegetation index, surface temperature, and spatial structure
which is derived from AVHRR, to detect land cover change in West Africa, the use
of curve change, and many other method.
2.4.1. ASTER
The Advanced Spaceborne Thermal Emission and Reflection Radiometer
(ASTER) is an advanced multispectral imager that was launched on board NASA’s
Terra spacecraft in December, 1999. ASTER covers a wide spectral region with 14
bands from the visible to the thermal infrared with high spatial, spectral and
radiometric resolution. An additional backward-looking near-infrared band provides
stereo coverage. The spatial resolution varies with wavelength: 15 m in the visible
and near-infrared (VNIR), 30 m in the short wave infrared (SWIR), and 90 m in the
thermal infrared (TIR). Each ASTER scene covers an area of 60 x 60 km.
ASTER consists of three different subsystems: the Visible and Near-infrared
(VNIR) has three bands with a spatial resolution of 15 m, and an additional
backward telescope for stereo; the Shortwave Infrared (SWIR) has 6 bands with a
spatial resolution of 30 m; and the Thermal Infrared (TIR) has 5 bands with a
spatial resolution of 90 m. Each subsystem operates in a different spectral region,
with its own telescope(s), and is built by a different Japanese company. The
spectral bandpasses are shown in Table 2.1, and a comparison of bandpasses with
Landsat Thematic Mapper is shown in Figure 2.4. In addition, one more telescope
is used to view backward in the near-infrared spectral band (band 3B) for
stereoscopic capability.

VNIR has high performance, VNIR subsystem consists of two independent
telescope assemblies to minimize image distortion in the backward and nadir
looking telescopes. The detectors for each of the bands consist of 5000 element
silicon charge-coupled detectors (CCD's). Only 4000 of these detectors are used at
any one time. A time lag occurs between the acquisition of the backward image
and the nadir image. During this time earth rotation displaces the image center.
The VNIR subsystem automatically extracts the correct 4000 pixels based on orbit
position information supplied by the EOS platform.
Chapter 2 – Literature Review
29
The VNIR optical system is a reflecting-refracting improved Schmidt
design. The backward looking telescope focal plane contains only a single
detector array and uses an interference filter for wavelength discrimination. The
focal plane of the nadir telescope contains 3 line arrays and uses a dichroic prism
and interference filters for spectral separation allowing all three bands to view the
same area simultaneously. The telescope and detectors are maintained at 296 ± 3K
using thermal control and cooling from a platform-provided cold plate. On-board
calibration of the two VNIR telescopes is accomplished with either of two
independent calibration devices for each telescope. The radiation source is a
halogen lamp. A diverging beam from the lamp filament is input to the first
optical element (Schmidt corrector) of the telescope subsystem filling part of the
aperture. The detector elements are uniformly irradiated by this beam. In each
calibration device, two silicon photo-diodes are used to monitor the radiance of
the lamp. One photo-diode monitors the filament directly and the second monitors
the calibration beam just in front of the first optical element of the telescope. The
temperatures of the lamp base and the photo-diodes are also monitored. Provision
for electrical calibration of the electronic components is also provided.
The system signal-to-noise is controlled by specifying the NE delta rho (ρ)
to be < 0.5% referenced to a diffuse target with a 70% albedo at the equator
during equinox. The absolute radiometric accuracy is ± 4% or better.
The VNIR subsystem produces by far the highest data rate of the three
ASTER imaging subsystems. With all four bands operating (3 nadir and 1
backward) the data rate including image data, supplemental information and
subsystem engineering data is 62 Mbps.
The SWIR subsystem uses a single aspheric refracting telescope. The
detector in each of the six bands is a Platinum Silicide-Silicon (PtSi-Si) Schottky
barrier linear array cooled to 80K. A split Stirling cycle cryocooler with opposed
compressors and an active balancer to compensate for the expander displacer
provide cooling. The on-orbit design life of this cooler is 50,000 hours. Although
ASTER operates with a low duty cycle (8% average data collection time), the
cryocooler operates continuously because the cool-down and stabilization time is
long. No cyrocooler has yet demonstrated this length of performance, and the
Chapter 2 – Literature Review
30
development of this long-life cooler was one of several major technical challenges
faced by the ASTER team.
The cryocooler is a major source of heat. Because the cooler is attached to
the SWIR telescope, which must be free to move to provide cross-track pointing,
this heat cannot be removed using a platform provided cold plate. This heat is
transferred to a local radiator attached to the cooler compressor and radiated into
space.
Six optical bandpass filters are used to provide spectral separation. No
prisms or dichroic elements are used for this purpose. A calibration device similar
to that used for the VNIR subsystem is used for in-flight calibration. The
exception is that the SWIR subsystem has only one such device.
The NE delta rho will vary from 0.5 to 1.3% across the bands from short to
long wavelength. The absolute radiometric accuracy is +4% or better. The
combined data rate for all six SWIR bands, including supplementary telemetry
and engineering telemetry, is 23 Mbps.
The TIR subsystem uses a Newtonian catadioptric system with an aspheric
primary mirror and lenses for aberration correction. Unlike the VNIR and SWIR
telescopes, the telescope of the TIR subsystem is fixed with pointing and scanning
done by a mirror. Each band uses 10 Mercury-Cadmium-Telluride (HgCdTe)
detectors in a staggered array with optical band-pass filters over each detector
element. Each detector has its own pre- and post-amplifier for a total of 50.
As with the SWIR subsystem, the TIR subsystem uses a mechanical split
Stirling cycle cooler for maintaining the detectors at 80K. In this case, since the
cooler is fixed, the waste heat it generates is removed using a platform supplied
cold plate.
The scanning mirror functions both for scanning and pointing. In the
scanning mode the mirror oscillates at about 7 Hz. For calibration, the scanning
mirror rotates 180 degrees from the nadir position to view an internal black body
which can be heated or cooled. The scanning/pointing mirror design precludes a
view of cold space, so at any one time only a single point temperature calibration
can be effected. The system does contain a temperature controlled and monitored
chopper to remove low frequency drift. In flight, a single point calibration can be
Chapter 2 – Literature Review
31
done frequently (e.g., every observation) if necessary. On a less frequent interval,
the black body may be cooled or heated (to a maximum temperature of 340K) to
provide a multipoint thermal calibration. Facility for electrical calibration of the
post-amplifiers is also provided.
For the TIR subsystem, the signal-to-noise can be expressed in terms of an
NE delta T. The requirement is that the NE delta T be less than 0.3K for all bands
with a design goal of less than 0.2K. The signal reference for NE delta T is a
blackbody emitter at 300K. The accuracy requirements on the TIR subsystem are
given for each of several brightness temperature ranges as follows: 200 - 240K,
3K; 240 - 270K, 2K; 270 - 340K, 1K; and 340 - 370K, 2K.
The total data rate for the TIR subsystem, including supplementary
telemetry and engineering telemetry, is 4.2 Mbps. Because the TIR subsystem can
return useful data both day and night, the duty cycle for this subsystem is set at
16%. The cryocooler, like that of the SWIR subsystem, operates with a 100% duty
cycle.
2.4.2. Satellite Landsat
The Landsat 5 is a Landsate satelite which was released on March 5th 1984
by NASA USA. It has the ability to detect every earth's surface and to send the
data to earth-stations worldwide. The satellite. will recheck the same area in 16-
day cycle, within 185km coverage from northpole to southpole, circling the
earth with sunsyncronous orbit, locating above the equator at 9.30am local time in
descending node.
Landsat 5 was developed from the previous Landsat satelites (1, 2 and 3)
with improvement on the spacial resolution, radiometric varieties, data transfer
with better speed, and vegetation-related focus. Development of Thematic Mapper
(TM) sensor with added thermal channels on the wave lenghth (10.40-12.50
micron). This canal is not available on Landsat 1, 2 and 3 with its MSS sensor.
Landsat 5 is a replica of a high ability Thematic Mapper. Adding a new specialty
that has multifuction and components that are more efficient for the global study
data, to monitor the area coverage and the size of the mapping area more
accurately than the previous design, and to show a stabil radiometric correction

2.5. Geography Information System (GIS) and Satellite imagery
Geography Information System is an information system that was
constructed to work with spatial reference data or those with geographic
coordinates. GIS can be associated as a map with high orde, which can also
operate and save non-spatial data. It was said that GIS has proven its reliability to
collect, save, process, analyze and show the spatial data on either biophysics or
social economy. Star and Estes stated that in general GIS provides the facilities to
take, manage, data manipulation and analysis, and to provide good quality results
on graphic and table, but its main function remains with managing the spatial data.
The advantage of GIS is its ability to attach data from different sources for
changes on detection application. However, combining data sources with different
accuration often affects the detection changes results. Lo (2002) used GIS
approach to calculate the impact of new city development in Hong Kong, through
the multi-temporal air images data integration on land use, and they found that the
overlay image with biner masking may be useful to quantitavely explain the
dynamics of changes on each land use category.
On the last year, the usage of multi-sources data (eg air images, TM, SPOT
and previous thematic map) have been an important method to detect changes on
land use and land cover (LULC), especially if the changes detection is part of a
long interval period connected to different sources, different format,
precision or changes analysis on multi-scale land cover (Muukkonen et al, 2006).

2.6 Biomass and C-Stock
Biomass was the name given to any recent organic matter that had been
derived from plants as a result of the photosynthetic conversion process. Biomass
is the mass (or weight) of living matter per unit area of ground. It is expressed in
units such as grams per square meter or kilograms per hectare. Between different
vegetation types, biomass range from around 100 kg/ha for desert and 500.000
kg/ha for tropical rain forest. In the study of carbon budget, biomass is important
because it directly represents the amount of carbon stored in living plants (Brown
S., 1997).
Aboveground biomass was difficult to quantify over large areas using
traditional techniques and executed the relationship between LAI derived from
NDVI and estimated aboveground biomass based on plant height. The
aboveground biomass of the plant could be easily estimated with some accuracy
from allometric relationship of trunk height (Brown S., 1997). Biomass ton per
hectare depend on the plant height (regression with model LAI) and planting
density.
This natural process was part of the carbon cycle and was known as
sequestration. Half of a tree mass was carbon, so large amounts of carbon were
stored in plants and they are the largest carbon store of terrestrial carbon. In most
ecosystems, most of carbon was stored below ground, either as roots and decaying
biomass or as organic carbon in the soil. The tree carbon calculation used general
allometric relationships to estimate aboveground biomass of the tree.
C-stock means the total Carbon which stored in the biomass component and
nekromass, above and inside soil (soil organic matter, plant root, and
microorganism) per unit area of ground.
2.6.1 Biomass Estimation
Biomass, an estimate of the total living or dead organic material expressed
as a weight per area (e.g. kilograms per hectare), has been of greatest interest
when aggregated over regional conditions (Penner et al., 1997; Schroeder et al.,
1997; Fang et al., 1998).
Chapter 2 – Literature Review
35
Traditionally, stand biomass estimates are derived by the same process as
regional estimation of biomass, by conversion of stem volume estimates from the
forest inventory database (Aldred and Alemdag, 1988). In less-well-inventoried
areas of the world, biomass estimates may be developed through forest cover type
volume tables (Brown and Lugo, 1984). The estimate begins with single tree
estimates by species and site types. The appropriate local allometric equations are
developed to partition the estimate into foliar, branch, stem and root biomass
estimates, or perhaps into two components: aboveground and belowground woody
biomass components (e.g. Lavigne et al., 1996). A recent strategy is to develop a
large-scale system for biomass estimation. Such an approach assumes that better
biomass estimates can be generated by referencing all available information in a
multistage approach: the forest inventory, the available satellite and airborne
imagery, and data collected in the field in permanent sample plots (Czaplewski,
1999; Fournier et al., 1999).
General equation, biomass density can be calculated from VOB/ha by first
estimating the biomass of the inventoried volume and then "expanding" this value
to take into account the biomass of the other aboveground components as follows
(Brown and Lugo 1992):
Aboveground biomass density (t/ha) = V * WD * BEF
where:
V = Volume of tree
WD = Wood density (1 of oven-dry biomass per m3 green volume)
BEF = Biomass expansion factor (ratio of aboveground oven-dry biomass of trees
to oven-dry biomass of inventoried volume)
Volume of tree = 7.0)2/(14.3 2××× hD
where:
D = DBH (Diameter Breast High), m
h = Height of tree, m
0.7 = Correction Factor
The linear regression equation approach requires the selection of the
regression equation that is best adapted to the conditions in the study area. Linear
regression models have been fitted to data in various situations of variable site and
Chapter 2 – Literature Review
36
ecological conditions globally. The work done by Brown, Gillespie and Lugo
(1989) and FAO (1997) on estimation of above ground biomass of tropical forests
using regression equations of biomass as a function of DBH is central to the use
of this approach. Some of the equations reported by Brown, Gillespie and Lugo
(1989) have become standard practice because of their wide applicability.
2.6.2. Carbon Sequestration
Carbon sequestration is the term describing processes that removes carbon
from the biosphere. A variety of means of artificially capturing and storing
carbon, as well as of enhancing natural sequestration processes, are being
explored. This is intended to support the mitigation of global warming.
A major proportion of the C and nutrients in terrestrial ecosystem is found
in the tree component. In photosynthesis process, trees absorb carbon dioxide
from the atmosphere and store it as carbon (part of carbohydrates) while oxygen is
released back into the atmosphere. Rapidly growing trees absorb a larger amount
of carbon dioxide. Mature trees grow less rapidly and thus have a lower intake of
carbon dioxide. While individual trees burned, die or decay, then it will release
most stored carbon back to the atmosphere, the forest as a whole continues to
store carbon as dying or harvested trees are replaced by natural regeneration
(Wikipedia, 2008).

Chapter 2 – Literature Review
37
The calculation of carbon stock as biomass consists of multiplying the total
biomass by a conversion factor that represents the average carbon content in
biomass. It is not practically possible to separate the different biomass
components in order to account for variations in carbon content as a function of
the biomass component. Therefore, the coefficient of 0.5 for the conversion
biomass to C, offered by IPCC (2003), is generalized here to conversions from
biomass to carbon stock: C = 0.5 × biomass (total). This coefficient is widely
used internationally, thus it may be applied on a project basis.
2.7. Error analysis
Estimating carbon stock changes, emissions and removals arising from Land
Use Land Use Change Forestry (LULUCF) activities have an uncertainties/error
that is associated with area or other activity data, biomass growth rates, expansion
factors and other coefficients. Uncertainty estimates are an essential element of a
complete emissions inventory. Uncertainty information is not intended to dispute
the validity of the inventory estimates, but to help prioritize efforts to improve the
accuracy of inventories in the future and guide decisions on methodological
choice.
In IPCC document (IPCC, 2003), two methods for the estimation of
combined uncertainties are presented: a Tier 1 method using simple error
propagation equations, and a Tier 2 method using Monte Carlo or similar
techniques. Both methods are applicable when dealing with the LULUCF sector.
However, some specific considerations have to be highlighted, because net
emissions can be negative if both emissions and removals are taken into account.
Use of either Tier 1 or Tier 2 will provide insight into how individual
categories and greenhouse gases contribute to the uncertainty in total emissions in
any given year, and to the trend in total emissions between years. Being
spreadsheet based, the Tier 1 method is easy to apply, and it is good practice for
all countries to undertake an uncertainty analysis according to Tier 1. Inventory
agencies may also undertake uncertainty analysis according to Tier 2 or national
methods. The uncertainty estimates of the LULUCF sector can be combined with
Chapter 2 – Literature Review
38
the uncertainty estimates of the non-LULUCF sector to obtain the total inventory
uncertainty.
Uncertainties should be reported as a confidence interval giving the range
within which the underlying value of an uncertain quantity is thought to lie for a
specified probability. The IPCC Guidelines suggest the use of a 95% confidence
interval, which is the interval that has a 95% probability of containing the
unknown true value. This may also be expressed as a percentage uncertainty,
defined as half the confidence interval width divided by the estimated value of the
quantity (figure 2.6). The percentage uncertainty is applicable when either the
underlying probability density function is known or when a sampling scheme or
expert judgment is used. Furthermore, this notion can be readily used to identify
the categories for which efforts to reduce uncertainty should be prioritized.

2.7.1. Monte carlo analysis
The principle of Monte Carlo analysis is to select random values of emission
factor and activity data from within their individual probability density functions,
and to calculate the corresponding emission values. This procedure is repeated
many times, using a computer, and the results of each calculation run build up the
overall emission probability density function. Monte Carlo analysis can be
performed at the source category level, for aggregations of source categories or
for the inventory as a whole (IPCC, 2003).
Monte Carlo analysis can deal with probability density functions of any
physically possible shape and width, can handle varying degrees of correlation
(both in time and between source categories) and can deal with more complex
models (e.g. the 1st order decay for CH4 from landfills) as well as simple
‘emission factor times activity data’ calculations.
Like all methods, Monte Carlo analysis only provides satisfactory results if
it is properly implemented. This requires the analyst to have scientific and
technical understanding of the inventory. Of course, the results will only be valid
to the extent that the input data, including any expert judgments, are sound.
The Monte Carlo approach consists of five clearly defined steps shown in
Figure 2.6. Only the first two of these require effort from the user, the remainder
being handled by the software package.
• Step 1 – Specify source category uncertainties. Specify the uncertainties in the
basic data. This includes emission factors and activity data, their associated
means and probability distribution functions, and any cross correlation
between source categories.
• Step 2 – Set up software package. The emission inventory calculation, the
probability density functions and the correlation values should be set up in the
Monte Carlo package.
The software automatically performs the subsequent steps.
• Step 3 – Select random variables. This is the start of the iterations. For each
input data item, emission factor or activity data, a number is randomly
selected from the probability density function of that variable.
Chapter 2 – Literature Review
40
• Step 4 – Estimate emissions. The variables selected in Step 3 are used to
estimate total emissions. The example given in Figure 6.1 assumes three
source categories, each estimated as activity multiplied by an emission factor,
and then summed to give total emissions. The calculations can be more
complex. Emissions by gas can be multiplied by GWP values, in order to
obtain total national emissions in CO2 equivalent. Correlations of 100% are
easy to incorporate, and good Monte Carlo packages allow other correlations
to be included. Since the emission calculations should be the same as those
used to estimate the national inventory, the Monte Carlo process could be
fully integrated into the annual emission estimates.
• Step 5 – Iterate and monitor results. The calculated total from step 4 is stored,
and the process then repeats from step 3. The mean of the totals stored gives
an estimate of the total emission. Their distribution gives an estimate of the
probability density function of the result. As the process repeats, the mean
approaches the final answer. When the mean no longer changes by more than
a predefined amount, the calculation can be terminated. When the estimate for
the 95% confidence range is determined to within ± 1%, then an adequately
stable result has been found. Convergence can be checked by plotting a
frequency plot of the estimates of the emission. This plot should be reasonably
smooth. These actions should be handled by the software, with the user
specifying either a number of iterations or convergence criteria.

3.3. Method
The process of this research is described as figure 3.2.
Figure 3.2. Flowchart of research
3.3.1. Project boundary/area development
Location of project area is in northern part of TNBTS, Blok Keciri is the
largest area for this study case. This location is recommended by TNBTS office,
field tracking by using Global Positioning System (GPS) is needed to derive the
boundary project. Project area can be varying in size from tens of hectares to
hundreds of hectares, and can be confined into several geographic areas. The
project area may be one contiguous block of land under, or many small blocks of
land spread over a wide area. The spatial boundaries of the land need to be clearly
defined and properly documented from the start to aid accurate measuring,
accounting and verification.
3.3.2. Land Cover Classification and Eligible land area development
Satellite image of Landsat 5 and Aster are the data that used for land cover
classification on the project area. Before starting the classification process, those
Chapter 3 - Methodology
44
satellite images have to be corrected (geometric and radiometric). To increase the
accuracy of the classification, fieldtruthing is required to conducted, and then
supervised classification process is the liable to be used. To avoid an independent
single pixel on an object, low pass filter will be used, in this method centre pixel
value will be replaced by average value of the surrounding pixel. The default
kernel size is 3 x 3.
After classification process was successfully done, the next step is defining
the eligible land for AR-CDM. Eligible land in this study is the land that suitable
and fulfilled the requirement of implementing reforestation CDM project, which is
the land has not been forested since 31 December 1989. Following Ministry of
Forestry Regulation Number 14/2004 and its Addendum that forest in Indonesia is
defined as land having a minimum area of 0.25 ha, a minimum tree crown cover
of 30%, and three that have minimum height of 5 m, lands which do not meet this
definition are bush/shrubs and savannah. Figure 3.3 shows the step of
classification process and eligible land development.

The A/R CDM project activity may contain more than one discrete parcel of
land. Each discrete parcel of land shall have a unique geographical identification.
The boundary shall be defined for each discrete parcel. The discrete parcels of
lands may be defined by polygons, and to make the boundary geographically
verifiable and transparent, the GPS coordinate for all corners of each polygon
shall be measured, recorded, archived and listed.
3.3.3. Carbon stock change estimation
The approved methodology to calculate and analyze carbon stock for large
scale afforestation/reforestation CDM project is provided in UNFCCC website
“http://cdm.unfccc.int/methodologies/ARmethodologies/approved_ar.html”.
Based on the characteristic of TNBTS which is degraded and covered by
grassland, the methodology that may be used is AR-AM0001/version 2
“Reforestation of degraded land”.
The flows of carbon stock change because of project activity are described
in figure 3.4. In order to asses the carbon stock change
Figure 3.4. Flow change of carbon stock on the project activity
Baseline; Carbon stock change on the project area with the absence of
project activity. For strata without growing trees, this methodology conservatively
assumes that the carbon stock in aboveground and below-ground biomass would
in the absence of the project activity remain constant, i.e., the baseline net GHG
removals by sinks are zero. Only the carbon stock changes in above-ground and
below-ground biomass (in living trees) are estimated.

For those strata with growing trees, the sum of carbon stock changes in
above-ground and below-ground biomass is determined based on the projection of
their number and growth, based on growth models (yield tables), allometric
equations, and local or national or IPCC default parameters (detail below in this

GHG emissions by sources/project area; the A/R CDM project activity
may cause GHG emissions within the project boundary, in particular. The
emission of CO2, CH4 and N2O from following sources may occur as a result of
the proposed A/R CDM project activity:
• Emissions of greenhouse gases from combustion of fossil fuels for site
preparation, thinning and logging; (No emission from this part, human
resources were used for this activities)
• Decrease in carbon stock in living biomass of existing non-tree vegetation,
caused either by competition of planted trees or site preparation including
slash and burn; (No emission from this part, the existing vegetation are still
living on the project area and there are no slash and burn activity for the site
preparation)
• Emissions of non-CO2 greenhouse gases from biomass burning for site
preparation (slash and burn activity); (No emission from this part, no slash and
burn activity)
• N2O emissions caused by nitrogen fertilization application.
Based on the information above, the GHG emission as a result of the
implementation of the proposed A/R CDM project activity within the project
boundary is estimated as follows:

project. The status of the project area is protected area, where by regulation it is

means that, there is no logging or getting fuelwood activity outside the project

3.3.4. Error analysis on Carbon stock change estimation
The size area that already defined by using remote sensing and GIS analysis
is contain some error, because there area several area that miscounted (area that is
not counted in the calculation process, in fact the area is suppose to be counted)
and over counted (area that is counted in the calculation process, but in fact the
area is not suppose to be counted), and also the volume of Casuarina
Junghuhniana and Acacia Decurens that have been calculated from diameter and
height of trees measurement to estimate the actual GHG removal by sinks is
contain some error. Crystal Ball tool that integrated with Microsoft Excel
application was used to analyze the error. The errors of area definition are
assumed as 5%, 10%, 15%, and 20%, which means that the errors is occur on the
processing of defining the 1134.5 ha of eligible land area. For growth error
estimation are also assumed as 5%, 10%, 15%, and 20%. The scenario of those
process are shown in Figure 3.5. The simulation estimation will take 2500 trials
and the error value will be modified as normal distribution.

IV. RESULTS & DISCUSSIONS
4.1. Location information
Geographically, the Bromo Tengger Semeru National Park lies between
7°51’ - 8°11’ S, and 112°47’-113°10’E with elevation of between 750 - 3.676 m.
a.s.l. Most of the area is undulating and hilly with slopes of 0 - 40%; most of the
remainder is mountainous with slopes of more than 20-30% (see Figure 4.1).
Types of ecosystem of the Bromo Tengger Semeru National Park consist of
sub-montana, montana and sub-alphin covered by big trees with age of more than
100 years such as ‘cemara gunung’ (Casuarina Junghuhniana), jamuju
(Dacrycarpus imbricatus), eidelweis (Anaphalis javanica), and various kind of
orchids and endemic grasses such as Styphelia pungieus.
The rainfall pattern is unimodal with one peak occurs around January.
Months with rainfall of less than 100 mm normally occurs between June-
September (Figure 5). The maximum temperature is about 22.° C and the
minimum temperature around 5° C. The relative humidity during the day is quite
dry about 43% during the day and during the night about 94 %.

Table 1. Main cause of fires comes from communities who made fires for heaters
during their travel to jungle for collecting mushroom and making charcoal.
People who are looking for mushroom in forests normally travel up to 7 days. In
the night they normally make fires.
4.2. Land Cover Classification and Eligible land area development.
The location that recommended by Kantor Taman Nasional Bromo Tengger
Semeru (TNBTS) for the project is in block Keciri, estimated area is
approximately 1200 ha. In order to delineate the boundary project, GPS tracking
directly to the field was conducted (Figure 4.2).
Figure 4.2. GPS field tracking.
Total area of target location after field tracking process has finished is about
1586 ha. During field tracking process, it is seen that most of the land cover type
on the location is savannah and few is bush/shrubs. Fieldtruthing process was

conducted together with field tracking process, this process is needed to
increasing classification accuracy level. Total of fieldtruthing points are 61, 19 of
fieldtruthing point were selected as a reference point for classification process
(supervised classification) and the rest are as independent reference point for
accuracy measurement (Figure 4.3).
Figure 4.3. Fieldtruthing point map
After the boundary of the target location has defined, and fieldtruthing
points have collected, the next step is the classification process using satellite data
(ASTER, acquisition date 2006-09-03). Supervised classification process is liable
to be used, an then to avoid an independent single pixel on an object, low pass
filter method was used, in this method centre pixel value will be replaced by
average value of the surrounding pixel. The accuration level of the classification is
quite good (83 %), it can be shown at Appendix 1. Land cover type of 1989 was
derived by using satellite data (LANDSAT 5, acquisition date 1989-03-28), in
order to increase the accuration level, additional information from local
correspondent who experienced well about the location is needed. The result of
both analyses is shown in Figure 4.4.

Following Ministry of Forestry Regulation Number 14/2004 and its
Addendum that forest in Indonesia under the KP is defined as land having a
minimum area of 0.25 ha, a minimum tree crown cover of 30%, and three that
have minimum height of 5 m, the lands which do not meet this definition are
bush/shrubs and savanna. Thus lands eligible for CDM are lands which are
bush/shrubs or savanna before 1990 and now are still bush/shrubs or savanna.
The total of eligible land for the project is actually about 1219.3 ha where
about 1134.5 ha covered by savannah and 84.8 ha by bush/shrubs. At the
methodology mentioned before, the biomass increment at baseline level has
described already, bush/Shrub is a growth species that can not be defined as a
forest, as this species can not reach a height of 5 m. It is difficult to define the
growth rate of Bush/Shrubs, because the data of this species is limited. The size
area of eligible land that covered by this species is only 84.8 ha, and it is not give

a significant influence. Therefore the eligible land that covered by bush/shrubs
was avoided, and the land that eligible for this project only 1134.5 ha which is
covered by savannah. The proposed project location is located at elevation
between 1440-2665 m a.s.l.
4.3. Carbon stock change estimation
Baseline; For strata without growing trees (savannah), the carbon stock in
aboveground and below-ground biomass would remain constant, the baseline net
GHG removals by sinks are zero.

Actual net GHG removals by sinks/project area; the actual net
greenhouse gas removals are calculated as follows:
∑∑ −∆=∆
i j
EjACTUAL GHGCiC
The estimates of the actual net GHG removals by sinks include the annual
carbon stock change in aboveground and belowground biomass of living trees
(∆Cij) and the direct N2O emission caused by fertilizer. Carbon stock change is
represented by the growth of trees (Casuarina Junghuhniana and Acacia
Decurrens). The growth are assumed and modified based on study literature,
Casuarina junghuhniana is a fast-growing deciduous tree 15-25 (max. 35) m tall;
trunk diameter 30-50 (max. 65) cm. The growth of this tree on the several sites in
east java can be shown on Table 4.3, the modified growth of this species is follow
the equation of Volume (m3/ha) = 449/(1+EXP(4.96-0.4123*E121)), described in
Figure 4.6. For Acacia Decurrens, no exact information about this species, IPCC
document on Average Annual above Ground Net Increment in Volume in
Plantations by Species quotes that Acacia Decurrens has an annual aboveground
volume increment around of 14 m3/ha/year, the modified growth of this species is
follow the equation of Volume (m3/ha) = 386/(1+EXP(5.14-0.4548*E121)),
described in Figure 4.7.

GHG emissions by sources/project area; the emission that may occur as a
result of the proposed A/R CDM project activity is only N2O emissions that is
caused by nitrogen fertilization application.
The indigenous vegetation on the proposed area is Casuarina Junghuhniana,
while Acacia Decurrens is exotic vegetation. Therefore, the composition of trees
that will be planted is 70% for Casuarina Junghuhniana and 30% for Acacia
Decurrens. Planting distance is 5m x 5m, this value comes from field survey on
the primary forest near by the project area, whether it is Casuarina Junghuhniana
and Acacia Decurrens. Total numbers of trees that will be planted on the proposed
area are: 10000/25 x 1134.5 = 453.800 trees, consists of 317.660 Casuarina
Junghuhniana and 136.140 Acacia Decurrens.
Planting process will be implemented in five years, each year around 227
Ha of proposed area will planted. Before planting the trees, fertilization will be
implemented, manure and urea will be used to fertilize the soil. Each hectare of
the land will be fertilized by 5000 Kg of manure mixed by 150 Kg of urea. In
1000 Kg manure contains about 5 Kg of N, and in 100 Kg urea contains about 46
Kg of N. Following the equation in chapter 3, total emission from fertilizer on the
proposed area are 107.4 t CO2e/year, this emission only occur in planting phase (5
years).
Based on the calculation (Appendix 2), the actual net GHG removals by the
project activity in the next 20 years is around 1.262.858 T CO2 (Figure 4.8, and
Table 4.4.).

Leakage; The identified potential leakage of the proposed A/R CDM project
activity may be GHG emissions caused by vehicle fossil fuel combustion due to
transportation of seedling, labours, and staff to and/or from project sites on
planting and monitoring phase.
Vehicles that will be used in this project are; truck (2 units), car (2 units),
and motorcycle (3 units). Distance from base camp to proposed area is 20 Km,
average fuel consumption of truck and car is 0.17 liters/km, while motorcycle is
0.03 liters/km, emission factor for each vehicle is 2.63 kgCO2/litre. Planting
activity will be conducted four months, regarding the equation in chapter 3, total
leakage or GHG emission outside boundary on planting phase (5 years) that
would occur under the presence of the project is about 17 t CO2e/year, while after

4.4. Error analysis on Carbon stock change estimation
Conservative approach was used in choosing parameters and making
assumptions, i.e. if different values for a parameter are plausible, a value that does
not lead to an overestimation of the actual net GHG removals by sinks or
underestimation of the baseline bet GHG removals by sinks should be applied.
From the error analysis process, can be seen that if the error of the size area is
bigger because of the resolution of satellite image is low, then the number of GHG
removal by sinks will decrease, because the low figure (red line) is the most
plausible unit that can be claimed as a carbon credit. This result is suggested that,
by using good resolution satellite imagery, the output/result is getting better. On
the scenario 5% error of area definition and 5% error of volume measurement, the
minimum actual GHG removal by sink is 1.196.844 T CO2e (Figure 4.10), while
in the scenario 20% error of area definition and 5% error of volume measurement,
the minimum actual GHG removal by sink is only 1.007.297 T CO2e (Figure
4.11). The difference is quite significant 189.547 T CO2e. So, it is necessary to
put more attention when we want to use satellite imagery.

High error on tree’s volume does not give significant difference to the value
of GHG removal by sinks, see Figure 4.12 is similar with Figure 4.10. But the
result of measurement will generate high variance of output, it is not liable by
having high variance on the output. Then, the standard operational procedure on
measuring diameter and height of trees are needed.

V. CONCLUSIONS AND RECOMMENDATIONS
5.1. Conclusions
There are several conclusions that can be drawn related to the research
objectives:
1. The eligible land area for carbon sequestration project on Bromo Tengger
Semeru National Park is around of 1134.5 Ha, which is covered by
savannah.
2. Carbon stock change at baseline in Bromo Tengger Semeru National Park is
zero, because the species that living on the proposed area is not growing
trees.
3. The actual net GHG removal by sinks under the presence of carbon
sequestration project at Bromo Tengger Semeru National Park in twenty
years is around of 1.262.858 T CO2e .
4. The leakage that occur under the presence of carbon sequestration project at
Bromo Tengger Semeru National Park is around of 17 t CO2e/year, while
after five years the annual leakage is only 50% of planting phase because the
activity will only focus on monitoring.
5. The net anthropogenic GHG removal by sink under the presence of the
carbon sequestration project at Bromo Tengger Semeru National Park in
twenty years is around of 1.262.648 T CO2e.

5.2. Recommendations
Recommendations as the result of this research are as follows:
1. Big/high error of size area definition caused by low resolution of satellite
image will decrease the value of GHG removal by sinks, because the low
figure (red line) is the most plausible unit that can be claimed as a carbon
credit. Using high resolution satellite imagery will increase the potency to
get high carbon credit.
2. Big/high error in trees volume measurement will make the output calculation
of GHG removal by sinks is not liable, because of the high variance.
Standard Operational Procedure is needed to avoid the error.
3. Databases of tree’s growth of Casuarina Junghuhniana and Acacia
Decurrens are necessary to define the biomass of trees.
