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.


  • Waterlogging is widespread in winter in the agricultural areas of Western Australia and is a major factor reducing crop yields, especially in wet years.

  • Poor germination or smaller yellow plants, in water collecting areas

    Waterlogging occurs when there is insufficient oxygen in the soil pore space for plant roots to adequately respire.

  • Regulation 6 of the Soil and Land Conservation Regulations 1992 requires any owner or occupier of land who proposes to drain or pump water from on or under the land and to discharge that water onto

  • Late-affected plants lodge and die prematurely

    Canola is more susceptible to waterlogging than cereals.

  • Mole drainage is a subsurface method of draining clay soils that experience regular waterlogging from irrigation or high rainfall.

  • The Agriculture and Food Division of the Department of Primary Industries and Regional Development (DPIRD) carries out the requirements of the Soil and Land Conservation Act 1945 to mitiga

  • Members of the public can lodge a complaint about observed land management with the Commissioner of Soil and Land Conservation in Western Australia, and the Commissioner will then investigate the c

  • Poor germination in waterlogged area.

    Waterlogging occurs when there is insufficient oxygen in the soil pore space for plant roots to adequately respire.

  • The Department of Agriculture and Food, Western Australia (DAFWA) recommends constructing shallow channels (shallow relief drains) to remove surface water from flooded land.

  • Harvesting crops on raised beds differs from harvesting on normal seedbeds only in terms of the constraints imposed by tracking the harvesting equipment in furrows if so desired.
