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.


  • Flooding in the Gascoyne River Catchment during the summer of 2010–11 caused the loss of an estimated 9 million tonnes of soil from erosion, and a damage bill of about $90 million.

  • Surface water management is needed wherever water erosion is a risk and where water movement control or water harvesting is required.

  • Following a fire, the risk of water erosion is greatly increased on bare paddocks.

  • Protecting your most vital water supply from contamination should be your first priority after a fire.

  • There are significant farm business benefits to reducing the risks from water erosion, and some of the options also increase available water on the farm and reduce down-stream problems.

  • Water erosion occurs when raindrops hit the soil surface and displace soil particles, and when water flowing over the land surface moves soil particles.
