Farming in a changing climate was the theme at the recent GRDC supported
WANTFA Conference in Perth.
Associate Professor Ross Kingwell, Chief Economist with DAFWA, addressed the
economics of climate change and the implications for growers.
He pointed out that projected climate change is a big challenge for farmers
and scientists because growing conditions in many parts of the traditional
grainbelt of WA could become less favourable.
WA is a major source of the nations grain exports, so responding to the
climate change challenge is in the national interest.
Professor Kingwell said many farms have diversified, with portfolios of
on-farm enterprises and off-farm investments, yet accompanying this
diversity is a skewed distribution of wealth and farm size. This has
implications for the sectors response to climate change.
Large businesses may be better able to spatially diversify, giving them the
potential to capitalise on, or modify, climate change and variability
The way forward for growers was to ensure their capacity to adapt was not
impaired. In the near term this meant improved options for managing current
He pointed to the need for collaboration between scientists and farmers to:
deliver more efficient water use; deliver new varieties with greater
drought, heat-shock and pest and disease resistance; reduce crop production
risk by staggered planting, better erosion control, minimal soil disturbance
and crop residue retention; facilitate crop operations via better weather
Professor Kingwell said simulation and projection studies show a complex
spatial story, where climate change impacts could vary greatly across
regions, with some facing much bigger climate challenges than others.
If the rate of climate change was faster than has been suggested, the
ability of farm businesses to adjust and remain profitable would be a real
He suggested that grower reliance on regionally relevant, climate related
and anticipatory R&D will increase. Appropriate innovation and adjustment
will be the keys to successful farming in the face of climate change, he
