The Managing Climate Variability Program will oversee 15 climate research projects, including seasonal climate forecasting for profitable sustainable resource use, the improved monitoring of evapotranspiration and enabling nationwide access to the Yield Prophet climate risk management information tool... The practicality and depth of projects funded under the new program provides an indication into the diversity and range of stakeholders with a keen interest in improving their understanding of climate," he says... The program"s communication coordinator, Tim Lester, says that growers will eventually be able to use the program"s website, www.managingclimate.gov.au , to download the latest climate variability decision-support tools, which he says are rapidly becoming essential business and risk management tools for agriculture in Australia...

ENSO remains best northern climate indicator.. The El Ni o/Southern Oscillation (ENSO) phenomenon remains recognised as the core driver of climate variability in eastern Australia, according to University of Southern Queensland climate researcher, Professor Roger Stone... "Although there are many climate patterns and systems that exist at widely varying time scales, the ENSO phenomenon remains recognised as the core driver of climate variability in eastern Australia," Prof Stone said...

Accepting the science of climate change does not mean discounting the importance of climate variability.. When discussing climate risk, it is important to understand how climate variability and climate change interact.. In many cases when growers question climate change, they are questioning a view of climate change that seems to deny the year-to-year and decade-to-decade variability...

The project has illustrated and quantified the historical variability associated with several climate products that are important to the Australian agriculture sector... The best methods for making the project outputs available are to be finalised, but suggestions include: via Climate Kelpie via something similar to, or an extension of, FutureWise working with Econnect Communication (www.econnect.com.au), or a similar company, to liaise with the Climate Champions program to determine which formats and ways of disseminating the information emerging from this project are most useful working directly with the Climate Champions in a similar way to how the Bureau of Meteorology(BoM) Water and the Land (WATL, www.bom.gov.au/watl) products are evaluated against user preferences via 'CliMate' - David Freebairn's 'Climate Analyser' tool... The project has illustrated and quantified, across Australia and for nine targeted grain growing regions, the climate variability that is already experienced and needs to be taken into account as part of climate risk management...

The El Ni o/Southern Oscillation (ENSO) remains the dominant source of climate variability and seasonal forecasting capability relevant for north-east Australia... The study shows that both sets of forecasts show widespread forecast skill in excess of climatology (ie better than the use of long-term average rainfall or temperature climatological statistics, but that the Bureau's forecasts perform better in the west of the country (Western Australia) and the Queensland SOI-phase forecasts performing better in the centre and east of Australia, including the northern cropping region (Fawcett and Stone, 2010)... Climate forecasts available for the northern cropping region, such as those based on or similar to the 'SOI-phase system', have been demonstrated to provide significant and relatively high skill when verification tests have been applied to assess all those forecasts in real-time over the past 10 years...

We used the tools to quantify the climatic risks related to farm management options such as crop rotation, sowing date, cultivar, and nitrogen management, at eight locations in SEA. During the life of the project farmers showed increasing interest in these tools so that many are now commonly in use... 16. A tool (software package) "Climate Variability Analyser" to simplify the analysis of climate variability has been produced... Significant changes were observed in shift and dispersion of the probability distribution functions for climate variables and grain yield among the SOI and SSTs phases calculated at the end of July...

Our GRDC-sponsored research aimed to quantify the economic value of the five SOI phases system (see note below) for tactical nitrogen management at mid-tillering in wheat in south-eastern Australia, and also to provide guidelines to improve profits without increasing the level of risk through exposure to climate variability... The study showed that higher profits, without increasing the level of risk of economic loss, can be achieved by adopting a seasonal forecasting system to determine the doses of nitrogen to be applied in split nitrogen applications between pre-drill and tillering... Rodriguez@dpi.vic.gov.au "Climate & Risk" provides information from the DPI project, "Tools to reduce the impact of climate variability in South Eastern Australia...

Dr Rohan Nelson, ABARE"s principal natural resources economist and co-author of the report - "Forecasting the regional impact of climate variability on Australian crop farm incomes" - hopes it will allow climate policy advisers to develop guidelines for more timely and better targeted drought assistance... Dr Nelson says that climate data that has been collected around Australia for many years is not as useful on its own as when put into the context of how rural communities cope with adverse climate conditions... Dr Nelson says that since current drought policy is focused on enhancing the self-reliance of farmers, increasing the diversity of farm income sources could be one of the most effective policy options for reducing the vulnerability of farm households to climate variability...

" Specifying Australia's climate Variability in the context of a changing climate.. Much has been made of the dangers and problems of a changing Australian climate for Australian agriculture... Detailed assessment for particular commodities has demonstrated that, out to at least the 2030 time horizon, coping with, and responding to, climate variability is of much higher importance than dealing with the projected impacts of anthropogenic climate change......
