Adaptation to climate change varies across Australia, depending on the climatic zone and the agricultural practices at play, whether farms are raising livestock, grains, orchards, stone fruit, wine grapes, fibres, or aquaculture.

By 2050, climate change is projected to halve the irrigated agricultural output of the Murray-Darling Basin region, which currently accounts for 50% of Australia’s irrigated agricultural output by value (about $7.2 billion per year)

This is just one of the economic impacts to the agriculture sector if adaptation is not undertaken, and this will only get worse if the mitigation strategies outlined below are not implemented. 

Broadly speaking, adaptation to climate change falls into a number of different categories: 

Information and forecastingWater management
Farming practicesForestry management (including fire management)
Land management 

Our plan

  • Adoption of an agreed set of metrics to measure progress towards ‘sustainable agriculture’. 
  • Reporting on our national progress against these metrics. 
  • Investment in the CSIRO and BOM to improve data, modelling and forecasting across the productive regions of the Australian continent and coastal waters 
  • Invest in RDC activities to promote adaptation and mitigation strategies
  • Encourage reforestation (through planting of native vegetation), reduction in land clearing and soil carbon capture (through the use of no-till techniques, planting native grasses, and other regenerative farming techniques)
  • Encourage the reduction in use of fertilisers, pesticides and intensive farming practices
  • Create a fund for farmers who deliver environmental benefits from their land. The Easiest mechanism would be to tie the ‘reward’ to carbon capture practices such as reforestation and soil carbon.
  • Create a levy allowing urban and rural Australians to more fairly share the costs of sustainable land management
  • Undertake a comprehensive water audit for the Murray-Darling Basin
  • Establish a new Murray Darling Basin Plan based on up-to-date and more accurate models of water falls, flows and usage
  • Fire management practices including integration of traditional fire management practices
  • A national fleet of water bombers (planes and helicopters) to be deployed to wildfires nation-wide on a needs basis on an estimated annual cost of $25 million
  • Invest in R&D for efforts into new plant species and management practices

Underpinning all efforts to adapt to climate change is the need for increased ‘resolution’ and quality of data relating to soil quality and composition, soil moisture, rainfall, and temperature. More accurate and more localised data paired with better forecasting models allow farmers to improve their short- and long-term decision-making. 

There is a need to align management and finance timeframes with environmental assessment timeframes and alleviate the short term financial pressure to enable landscape managers to develop and implement long term management plans. 

We need to look at ways to further drive innovation in the agricultural sector so that farmers are able to access world-class research, methods, and equipment.

Most agricultural sectors have a Research & Development Corporation which should be encouraged to collaborate more with universities and the CSIRO on activities aligned to the overall objectives of this Plan.  

[Discussion note re levy: the target of this levy is not defined. It has been suggested that it apply to domestic and international produce that do not meet environmental standards, to level the playing field for sustainable agriculture. In some sense, it can be thought of as Medicare for our environment.] 

By 2050 climate change is projected to halve the agricultural output of the Murray-Darling Basin region, but with few exceptions^ water variability is a major cause of concern across the Australian continent. Water licenses, allocations, buy-backs, ‘overland flows’, and environmental flows are all areas of policy needing to be addressed. Important considerations include: 

  • avoiding ‘market solutions’ to water issues 
  • factoring into policy decision-making the impact on the health and well-being of rural communities in keeping with the definition of ‘sustainable agriculture’; 
  • maintaining the environmental health and biodiversity of the river ecosystem across the length and breadth of the Murray-Darling Basin; 
  • providing town drinking water for our rural and regional communities; 
  • adequate and accurate measurement of water availability and usage. 

“What this really means is that society is going to have to make some hard choices. How much irrigated agriculture do we want as a society versus how much do we want to retain by way of wetlands and ecosystems [or] of sites of cultural value to Indigenous people?” 


The biggest risk to forestry practices in Australia comes from:

  • rises in temperature, particularly at the extremes; 
  • changes in total rainfall and seasonal rainfall distribution manifesting as changes in soil water availability;
  • changes in atmospheric CO2 concentration; and 
  • increased frequency or intensity of storms or flooding and weather conditions producing large-scale wildfires. 

Traditional ‘windows’ for fire management operations such as hazard and load reduction are narrowing as drier, hotter winters create hazardous conditions for much of the year.

Some parts of Australia are expected to receive higher-than-average rainfall as a result of climate change. Others are yet to be impacted by the shifts in rainfall patterns.
