New Chair for CRC for Greenhouse Accounting
Professor Emeritus John Lovett has accepted an invitation to become
Chairman of the Cooperative Research Centre for Greenhouse Accounting.
Professor Lovett, who is currently Managing Director of the Grains
Research and Development Corporation, will take up the role of Chairman
from the beginning of 2004.
He replaces the CRC’s inaugural Chairman, Sir Rupert Myers,
who retires on June 30, 2003. The Deputy Chairman of the CRC, Mr
John Buttle, will Chair the CRC until Professor Lovett takes up
his appointment.
In a statement to CRC partners, members and staff, Sir Rupert said
last week that as he looked back over four years of association
with the CRC for Greenhouse Accounting he realised that much had
been achieved. “The Centre is producing excellent and useful
scientific results and there are good prospects that outputs and
outcomes in the pipeline will be of major significance,” he
said.
Non-CO2 greenhouse gases
The CRC for Greenhouse Accounting is about to commence its new
program of research into emissions of non-CO2 greenhouse
gases in agricultural systems.
The program, made possible through approval of a supplementary
bid submitted by the CRC, offers a coordinated national approach
that will improve the efficiency of targeted agriculture systems
— grains, cotton and dairy — while reducing the nation’s
greenhouse gas account.
In the new program, researchers will appraise the effectiveness
of an array of options for reducing non-CO2 greenhouse
gas emissions from dairy, grains and cotton farming enterprises,
and contribute to the development of efficient farming systems and
best management practices to reduce emissions, particularly of nitrous
oxide from soils, fertiliser and urine, and methane from ruminants.
The program includes a range of strategies to establish dialogue
with agriculture extension providers and to tap into existing industry
networks to help in communicating research results and outputs to
farmers.

Towards zero emissions
CRC for Greenhouse Accounting Chief Executive Dr Chris Mitchell
will speak at the Towards Zero Emissions conference on strategies
and technologies for reducing greenhouse gas emissions in Brisbane
and 21 and 22 July, 2003.
The conference is supported by the Cooperative Research Centres
for Greenhouse Accounting, Greenhouse Gas Technologies, Coal in
Sustainable Development, and Clean Power from Lignite, and the National
Hydrogen Association of Australia.
Dr Mitchell will detail the key factors in biological sequestration,
assessing strengths and weaknesses and considering current and future
opportunities.
Other speakers in the program include Dr Graeme Pearman, Chief
Scientist, CSIRO Atmospheric Research; Mr Mark O’Neill, Executive
Director, Australian Coal Association; Dr John Wright, Director,
Energy Transformed Flagship, CSIRO Energy Technology; Dr Chris Spero,
Manager Engineering Technology, CS Energy; and Ms Fiona Nicholls,
General Manager – Sustainable Development, Rio Tinto Energy
Group.
The conference will discuss issues around both geological and biological
sequestration, gasification, and moving towards a hydrogen economy.
The world’s only operating geological sequestration project
and the first coal-based zero emissions electricity and hydrogen
power plant will be showcased.

Good Practice Guidance
The Intergovernmental Panel on Climate Change (IPCC) has developed
guidelines to assist nations to account for their greenhouse gas
emissions. Known as the IPCC Guidelines for National Greenhouse
Gas Inventories, they are used to bring international comparability
to reporting by individual nations. Along with these guidelines,
the IPCC produced Good Practice Guidance that identifies good practice
in calculation of inventories.
The current version of the Guidelines was developed in 1996, before
negotiation of the Kyoto Protocol in 1997.
Good Practice Guidance was adopted in 1998. However, due to the
then recent negotiation of the Kyoto Protocol and the complexity
of accounting for sources and sinks related to land-use, land-use
change and forestry, it was decided to develop Good Practice Guidance
for these sectors at a later date.
The Kyoto Protocol and its interpretation under the Marrakesh Accords
introduced a range of new requirements for accounting for carbon
fluxes in terrestrial ecosystems.
With the negotiation of the Marrakesh Accords in November 2001,
international negotiators asked the IPCC to develop Good Practice
Guidance for Land-use, Land-use Change and Forestry and to elaborate
upon the Guidelines for National Greenhouse Gas Inventories sufficient
for nations to be able to undertake their accounting to meet the
requirements of the Kyoto Protocol.
Several members of the CRC for Greenhouse Accounting are directly
involved in contributing to the development of the Good Practice
Guidance for Land-use, Land-use Change and Forestry as expert authors.
The CRC participated in the expert review of the first-order draft,
and recently has also responded with about 500 comments on the second-order
draft.
Following the submission of comments on the second-order draft,
the expert author teams will develop a final draft which will be
brought to government consideration in October 2003, and then is
expected to be adopted later in the year.

for Land-use, Land-use Change and Forestry see: http://www.greenhouse.crc.org.au/goodpractice/index.htm

transformation of a seasonally flooded Australian savanna. Journal
of Biogeography: (http://www.blackwellpublishing.com/journal.asp?ref=0305-0270)
30: 783-802.
Abstract: Aim: Anecdotal historical and photographic evidence
suggests that woody vegetation is increasing dramatically in some
northern Australian savanna habitats. Vegetation change in savannas
has important implications for pastoral land-use, conservation management,
and landscape-scale carbon storage, and informs theoretical debates
about ecosystem function. This study seeks to determine the nature,
extent and cause(s) of woody vegetation change in a seasonally flooded
alluvial savanna habitat. Results: There has been a dramatic
increase in woody vegetation cover throughout the study area. Demographic
analyses reveal that woody invasions have been episodic and indicate
that in most locations peak woody species establishment occurred
in the mid-1970s. Main conclusions: The only hypothesis consistent
with the evidence is: (1) observed changes are a direct consequence
of extreme overgrazing by cattle, most likely when stocking rates
peaked in the mid-1970s; (2) prolonged heavy grazing effected the
complete transformation of much of the herbaceous vegetation to
a new state that is not flammable; and (3) in the absence of regular
fire mortality, woody vegetation increased rapidly.

Terrestrial Biosphere Absorbs 7 to 12% of European Anthropogenic
CO2 Emissions. Science (http://www.sciencemag.org)
300: 1538-1542. Abstract: Most inverse atmospheric models
report considerable uptake of carbon dioxide in Europe's terrestrial
biosphere. In contrast, carbon stocks in terrestrial ecosystems
increase at a much smaller rate, with carbon gains in forests and
grassland soils almost being offset by carbon losses from cropland
and peat soils. Accounting for non–carbon dioxide carbon transfers
that are not detected by the atmospheric models and for carbon dioxide
fluxes bypassing the ecosystem carbon stocks considerably reduces
the gap between the small carbon-stock changes and the larger carbon
dioxide uptake estimated by atmospheric models. The remaining difference
could be because of missing components in the stock-change approach,
as well as the large uncertainty in both methods. With the use of
the corrected atmosphere- and land-based estimates as a dual constraint,
we estimate a net carbon sink between 135 and 205 teragrams per
year in Europe's terrestrial biosphere, the equivalent of 7 to 12%
of the 1995 anthropogenic carbon emissions.

30: No 7, 1405 Abstract: We examine seasonal variability
in snow-cover, normalized difference vegetation index (NDVI), and
temperature in a broad region of northern Eurasia, and the spatial
and temporal correspondence among trends in these variables between
1982 and 1999. Our results support the contention that the previously
reported springtime “greening” trend in northern Eurasian
land areas arises from a combination of: (1) the direct effects
of declining snow-cover on surface spectral reflectance and NDVI,
and (2) enhanced vegetation growth and green biomass stimulated
by warmer air temperatures and potentially greater vegetation absorption
of photosynthetically active radiation (PAR) during the period of
annual peak solar irradiance.

Climate-Driven Increases in Global Terrestrial Net Primary Production
from 1982 to 1999. Science (http://www.sciencemag.org)
300: 1560-1563. Abstract: Recent climatic changes have enhanced
plant growth in northern mid-latitudes and high latitudes. However,
a comprehensive analysis of the impact of global climatic changes
on vegetation productivity has not before been expressed in the
context of variable limiting factors to plant growth. We present
a global investigation of vegetation responses to climatic changes
by analyzing 18 years (1982 to 1999) of both climatic data and satellite
observations of vegetation activity. Our results indicate that global
changes in climate have eased several critical climatic constraints
to plant growth, such that net primary production increased 6% (3.4
petagrams of carbon over 18 years) globally. The largest increase
was in tropical ecosystems. Amazon rain forests accounted for 42%
of the global increase in net primary production, owing mainly to
decreased cloud cover and the resulting increase in solar radiation.

analysis of predicted change in soil carbon following afforestation,
Ecological Modelling (http://www.elsevier.com/locate/ecolomodel)
164: 137-152. Abstract: A credible and cost-effective methodology
is needed to support the use of new tree plantations to offset greenhouse
gas emissions, and ultimately to form part of an emissions trading
scheme. A number of validated models of forest growth are available.
However, there has been relatively little validation of models to
predict changes in pools of C in litter and soil, and thus suitable
for C accounting. A modelling approach is needed to track changes
in soil C because direct measurements are currently cost-prohibitive.
Modelling approaches also allow for scenario analyses that can be
useful for planning purposes. We used a complete C accounting model
for forests, GRC3, to simulate patterns of change in soil C following
afforestation under four test cases representing typical conditions
in Australia. Soil C was predicted to initially decrease (usually
during the first 10 years) before a gradual recovery and accumulation
of soil C occurred. Sensitivity analyses were used to determine
which parameters and inputs potentially cause the greatest uncertainty
in calculated change in soil C using GRC3. Taking into account the
uncertainties in the values of parameters and inputs, initial (0–10
years) decrease in soil C was predicted to be 0.96–2.35% per
year (or 4.16–14.8 t C ha-1) with a standard deviation between
0.10 and 0.43% per year among case studies, whereas the predicted
increase in soil C (10–40 years) was predicted to be between
0.49 and 1.80% per year (or 7.57–24.4 t C ha-1) with a standard
deviation between 0.18 and 0.69% per year. Results indicated that
uncertainty could be greatly reduced by calibration of the fraction
of above-ground litter transferred to soil C (i.e. humification),
fraction of C lost by respiration during decomposition of litter,
dead roots and soil C, and decomposition rates of the soil C pools.
It was also important to obtain accurate input data for initial
soil C content (including inert soil C), climatic conditions and
allocation of net primary production to various tree components.
