Climate change

Western Australia's climate has changed over the last century, particularly over the last 50 years. Climate change is affecting Australia's natural environment and the human systems it supports. Agriculture is strongly affected by weather patterns and climate. The Department of Primary Industries and Regional Development continues to engage with the agricultural industry to manage the impacts of climate change.


  • Climate change is putting pressure on wheat yields in south-west Western Australia (WA) in several ways: lower annual and autumn and spring rainfall; later starts to the growing season; higher temp

  • Climate change will affect horticultural production in Western Australia (WA) in a number of ways, and the effects will depend on location, soil type, crop type and management.

  • Climate projections for northern Australian Rangelands, including the Pilbara, are that temperatures will continue to rise; the intensity of heavy rainfall events will increase; and natural variabi

  • Climate change will affect each pastoral region in different ways.

  • Western Australia's climate has changed over the last century, particularly over the last 50 years. Average temperature has risen about 1°C.

  • The Australian Government's 2015 inventory of the nation's sources and sinks of greenhouse gases shows agriculture was responsible for about 16% of Australia’s greenhouse gas emissions in 2013.

  • Climate change in south-western Western Australia is a reality. There have been increased temperatures, decreased annual rainfall and increased climate variability.

  • Climate change will affect livestock production in the agricultural areas of Western Australia in different ways, with some regions and enterprises benefiting and some not.

  • DPIRD is committed to supporting livestock producers and the wider industry in their understanding of carbon emissions by enterprise and is taking mitigation action towards achieving carbon neutral

  • Climate projections for Western Australia (WA) are that average annual temperature will increase by 1.1–2.7°C in a medium-emission scenario, and 2.6–5.1°C in a high-emission scenario by the end of
