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.

Sharp, B.R. and Whittaker, R.J., The irreversible cattle-driven 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.

Europe’s 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.

Geophysical Research Letters (http://www.agu.org/journals/gl/) 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.

Paul, K.I., Polglase, P.J., Richards, G.P., Sensitivity 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.
