Bioenergy And Carbon Farming Opportunities In The Pilbara, Robert Sudmeyer, Kim Brooksbank, David Rogers Dec 2016

Bioenergy And Carbon Farming Opportunities In The Pilbara, Robert Sudmeyer, Kim Brooksbank, David Rogers

Bulletins 4000 -

The Pilbara region covers 270 000 square kilometres of north-west Western Australia. Its main agricultural land use is pastoralism, with beef cattle grazing native pastures. Currently, only 24km2 is under irrigation, with irrigated fodder the principal crop, but this could expand to 100km2. This expansion has the potential to significantly broaden the economic base of the Pilbara.

Irrigation and the opportunities for changing land use and management may facilitate greater participation in the carbon economy by Pilbara land managers. Bioenergy feedstocks could be sourced from purpose-grown crops or agricultural wastes. Carbon farming activities may be facilitated by …

Roaded Catchments To Improve Reliability Of Farm Dams, David Stanton Jun 2005

Roaded Catchments To Improve Reliability Of Farm Dams, David Stanton

Bulletins 4000 -

Maintaining reliable on-farm water supplies is an on-going challenge for landholders throughout Western Australia. Improving reliability of dams by constructing a roaded catchment is one of the most cost-effective methods of improving the performance and reliability of a farm water supply.

A roaded catchment is a water-harvesting structure designed to increase the amount of run-off from the catchment above a dam. The 'roads' of a roaded catchment are parallel ridges of earth with batters (or side slopes) that cause run-off to be directed into troughs or channels. The surface is lined with clay and compacted to make it smooth and …

Wheatbelt Waterwise = Saltwise : Gardening Guide, John Colwill, Juana Roe Jan 2004

Wheatbelt Waterwise = Saltwise : Gardening Guide, John Colwill, Juana Roe

Bulletins 4000 -

As a result of agricultural clearing, many country towns are now feeling the effects of rising groundwater and the salt that it carries. Salinity has been identified as Australia’s number one environmental problem. While most people think that salinity means land lost to agriculture, it also poses a serious threat to many country towns. A report for the Department of Agriculture in 2001 highlighted the need for simple and cost-effective salinity management strategies to be adopted in wheatbelt towns. These included water recycling, revegetation and more efficient water use.
