Indicator guidelines: toxicant concentrations

Estuarine, coastal and marine habitat condition

This document presents the recommended monitoring guidelines for sample collection, analysis, collating and reporting information on toxicant concentrations for national, state/territory and regional applications.

Indicator guidelines: presence of litter (rubbish and marine debris)

Estuarine, coastal and marine habitat condition

This document presents the recommended monitoring guidelines for collecting, collating and reporting information on the presence of litter in estuarine, coastal and marine waters for national, state/territory and regional application.

Subsurface Irrigation

National Program for Sustainable Irrigation Fact sheet 2005/1

Australian studies show an average of 30% of applied irrigation water passes through the root zone without being used by the crops it is intended to sustain. This water either becomes groundwater recharge or is intercepted by drainage networks and contributes to waterway pollution. Subsurface drip irrigation has shown great potential for increasing crop yield and uniformity, while decreasing water use and environmental impact. Importantly, subsurface irrigation applies water directly to the (more)...

Model for Effluent Disposal Using Land Irrigation (MEDLI) Technical Description

MEDLI® is a Windows® based computer model for designing and analysing effluent disposal systems for intensive rural industries, agri-industrial processors (e.g. abattoirs) and sewage treatment plants using land irrigation. It was developed jointly by the CRC for Waste Management and Pollution Control, the Queensland Department of Natural Resources and the Queensland Department of Primary Industries.

Investigations for Risk Assessments

NPSI Factsheet No. 2

The sustainability of Australia’s irrigation industry is currently under serious challenge. Irrigation uses ca. 75% of the water extracted from Australia’s rivers and groundwater systems, contributes to the pollution load in these rivers, and often leads to degradation of the irrigated land. In response to these challenges, the National Program for Sustainable irrigation (NPSI) has established an Ecological Risk Assessment Project, the overall objective (more)...

Irrigation Ecological Risk Assessment Project

NPSI Factsheet No. 1

Irrigated agriculture is a major contributor to the economic and social well being of Australia. Each year it produces around $10 billion of agricultural output or 50% of the country’s net agricultural profit. However, the sustainability of this important activity is currently under serious challenge. Irrigation uses 75% of the water extracted from Australia’s rivers and groundwater systems. It also contributes to the pollution load in these rivers. In response to (more)...
