Vegetation and Inland Aquatic Ecosystems

Remote Sensing Information Products

The objective of this project was to investigate the use of long term satellite images to develop nationally consistent, interpreted data and information products to support reporting on the Natural Resource Management (NRM) programs National Monitoring and Evaluation Framework - Matters for Target. These include condition and trend products as well as providing baselines and contextual information for regional planning and target setting processes. This project (more)...

Vegetation clearing as a threat

Fast Fact 38

The clearing of native vegetation is a threatening process operating on both ecosystems and species. The Audit’s Terrestrial Biodiversity Assessment identified regions where vegetation clearing threatens biodiversity.

Views on Irrigation Policy in Australia

Water policy in Australia is undergoing considerable and unprecedented change. Most recently, the emphasis on the sustainable management of water resources in the Murray Darling Basin has seen a shift of control from the States to the Commonwealth. The declining availability of water and the subsequent approaches taken by governments, have come under increasing scrutiny from the public. Indeed, the actions associated with water policy in Australia, particularly water used for irrigated (more)...

Vital Role for Australian Irrigation - 2008

Discusses irrigation in Australia in the context of global food security, decreasing water resources and the contribution of research and development to innovation.

Vital Role For Australian Irrigation - 2012

Thi fact sheet summarises Australia’s role in global irrigated food production. Australia’s irrigators have a vital role to play in meeting the challenge of global food security in the context of climate change and a growing global population. With population growth and standards of living and diet increasing in some regions, the demand for food will double in coming decades. Irrigation currently provides 40% of world food supplies and is projected to meet 60% (more)...

Wastewater recycling in nurseries

National Program for Sustainable Irrigation Fact sheet 2005/3

Reducing water run-off, minimising nutrient leaching and optimising irrigation efficiency are major challenges for the nursery industry. A comprehensive review of Australian and international research programs covering all aspects of waste water management in nurseries has been carried out by Horticulture Australia Limited (HAL) - a funding partner for the National Program for Sustainable Irrigation. The review identified useful resources for the industry and best practice in (more)...

Water allocation to River Murray wetlands: a basin-wide modeling approach

The primary aim of this project was to relate the water regime preferences of wetland plants to hydrology throughout the Murray River Basin and to predict the volume of additional water required to achieve optimal plant species diversity. This report details the methods and key findings of the project which examined the impact of regulation and changes in water allocation on the community composition of wetland plants through the Murray River basin. Due to a lack of primary data, it deals (more)...

Water Allocation to the River Murray wetlands

A basin wide modeling approach

How much water do the wetlands of the Murray River need? This project developed a model of the wetland plant community in 2,746 wetlands from the NSW and Victorian portions of the Murray River basin. The model used as data the average length of time out of each year each wetland was connected to the River Murray over the period 1990-2000. This value, called the connectivity, quantifies the wetting-drying cycle of a wetland. It describes the gradient between a (more)...

Water erosion hazard

Indicator protocols for soil condition

Water erosion causes losses of soil that far exceed the rates of soil development and the on-site consequences affect agriculture by: decreasing soil volume available for the plant root to exploit selectively removing nutrients and organic matter breaking up paddocks into physically smaller units. Off-site effects relate to the sedimentation of creeks, rivers, estuaries and reservoirs, increased flooding, eutrophication, and the general (more)...

Water Quality History of Murrumbidgee River Floodplain Wetlands

The condition of floodplain wetlands is a function of internal and external forces and functions. Wetlands vary longitudinally down a floodplain following principals enshrined in the River Continuum Concept whereby the nature and concentration of solutes and sediments change with distance from source. This observation pertains directly to the main river channels but influences the wetland mostly in times of flood as,during low flow,connection between the river and the wetland may be severed.
