Groundwater Trend Analysis And Salinity Risk Assessment For The South-West Agricultural Region Of Western Australia, 2007–12, G Paul Raper, Russell Speed, John Andrew Simons, A L. Killen, Andrew Blake, A T. Ryder, Rosemary H. Smith, Grant Stainer, L Bourke

Resource management technical reports
Dryland salinity is a hydrologically driven land degradation hazard in the south-west agricultural region of Western Australia (WA). Shallow-rooted annual crops and pastures transpire significantly less water than the native vegetation they replaced, leading to an increase in recharge, rising groundwater levels and the development of shallow watertables in areas where often none existed previously. Rising groundwater levels mobilise soluble salts, naturally stored at high concentrations in the regolith. These salts can be concentrated in the root zone of vegetation by evapotranspiration.
Goomig Farmlands Development Baseline Water Quality In The Lower Keep River, D L. Bennett, Richard J. George Dr
Goomig Farmlands Development Baseline Water Quality In The Lower Keep River, D L. Bennett, Richard J. George Dr
Resource management technical reports
In 2008 the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain. By mid-2014 construction of almost all of the water supply, drainage, access, monitoring and other infrastructure for the 7400ha Goomig Farmlands development had substantially been completed. An important concern is the effect the Goomig Farmlands development may have on the water quality of the downstream lower Keep River aquatic environment, particularly as it relates to threatened species that inhabit or may inhabit the area. Possible increases in salinity, nutrients, suspended sediment, heavy metals and farm chemicals delivered in …

This report aims to provide a summary of national and international activity in the use of agricultural by-products for the production of bioenergy and biofuels. The summary is primarily an internal report for the Department of Agriculture and Food, Western Australia (DAFWA), but will hopefully be of some value to industry proponents that are interested in pursuing the opportunities provided by what are currently low value agricultural waste products. We outline three processes for obtaining energy from these by-products that may be appropriate for the farming sector in Western Australia (WA).

Salinity Risk Mapping For Assessing Carbon Farming Initiative Proposals: Decision Support And Data Requirements, Paul Raper, Peter Gardiner
Salinity Risk Mapping For Assessing Carbon Farming Initiative Proposals: Decision Support And Data Requirements, Paul Raper, Peter Gardiner
Resource management technical reports
The Clean Energy Legislation passed by the Australian Parliament on 8 November 2011 links the carbon price to the Carbon Farming Initiative (CFI). Under the Carbon Credits (Carbon Farming Initiative) Act 2011 (the Act), proponents need to consider regional natural resource management (NRM) plans to ensure that tree plantings for carbon bio-sequestration maximise environmental benefits and avoid unintended adverse effects on biodiversity, water and agricultural production systems.
Potential Eradication And Control Methods For The Management Of The Ascidian Didemnum Perlucidum In Western Australia, Julieta Muñoz, Justin I. Mcdonald
Potential Eradication And Control Methods For The Management Of The Ascidian Didemnum Perlucidum In Western Australia, Julieta Muñoz, Justin I. Mcdonald
Fisheries research reports
In Western Australia, the invasive colonial ascidian Didemnum perlucidum was first detected in the Swan River Estuary in 2010 and subsequently recorded at multiple locations across the State. Ongoing research by the Department of Fisheries (the Department) indicates that this species exhibits strong seasonal changes in abundance. Although, D. perlucidum is able to reproduce sexually (larvae) and asexually (budding) year round, larvae density and settlement, and overall colony size significantly decreases during the colder months (winter). From a management point of view this period would present the best opportunity for an attempt at eradication or control of this species.
Broome Sandstone Aquifer, La Grange Groundwater Area: A Preliminary Report On The Hydrochemistry And Groundwater Recharge Rates, With Recommendations For Future Drilling And Environmental Tracer Sampling, Glenn A. Harrington
Natural resources commissioned reports
Innovative Groundwater Solutions has been engaged by the Department of Agriculture and Food, Western Australia (DAFWA) to assist with the initial planning and design of the drilling and groundwater sampling program for the Broome Sandstone aquifer in the La Grange groundwater area.
There are multiple objectives of the drilling program, including defining aquifer stratigraphy and position of the salt-water interface; assessing groundwater recharge, residence time, lateral flow velocity and the source of water to culturally significant sites; enabling long-term monitoring of water level and water quality; and, ultimately, developing a groundwater model for the aquifer.
The following four tasks were …

Carbon farming activities need to return multiple economic and environmental co-benefits to be attractive to land managers. This bulletin summarises concepts underlying carbon farming, how Australia accounts for greenhouse gas emissions and the potential for Western Australian land managers to participate in, and benefit from, carbon farming.
