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.
