Climate, land & water

Western Australia’s agriculture sector needs access to productive soil and water resources for growth and profit. However, the sector must compete with increasing resource demands from all sectors of the community, and the pressures of a changing climate. The Agriculture and Food division of the Department of Primary Industries and Regional Development supports agriculture by providing long-term management solutions, practical risk management strategies and tools to maintain and improve resource conditions, to meet the needs of industry and stakeholders. Agriculture and Food is also pioneering soil and water investigation of the state’s undeveloped areas to establish new irrigated agricultural industries.


  • Human-induced regeneration carbon farming provides an opportunity to increase the economic value of the State’s natural assets and contribute positively to Western Australia's ongoing prosperity.

  • The whole farm nutrient mapping procedure described here applies to pastures in the greater than 600mm rainfall zone of south-west Western Australia.

  • Ribbon grass pastures are one of the many pasture types in the pastoral rangelands in the Pilbara region of Western Australia.

  • To successfully establish saltbush with an understorey, choose the right species, use good seed or seedlings, minimise waterlogging, and use the right establishment methods.

  • Saltland pastures always have a range of plant species, even in dense saltbush plantations.

  • Surface water management is needed wherever water erosion is a risk and where water movement control or water harvesting is required, and as part of a salinity management program.

  • This dryland salinity option is recommended for saline sites in the south-west of Western Australia that are too saline, waterlogged and/or inundated for other treatments to succeed.

  • 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
