AWR 2005 meeting the needs of the NWI

The Commission has set AWR 2005 a set of key questions (refer to table below). The answers are a key deliverable that will effectively define the baseline condition upon which the success of the National Water initiative (NWI) will be measured.

NWI basis of the Baseline Water Resource Assessment

 NWI objective

 Key questions for AWR 2005

 AWR 2005 achievements

Objective (iii) statutory provision for environmental and other public benefit outcomes, and improved environmental management practices

  • How can we measure the delivery of environmental and other public benefit outcomes, and the successful protection of high conservation systems?
  • What baseline do we need?
  • What are the high conservation systems (rivers, reaches and groundwater areas), and environmental assets and any other public benefit outcomes identified?
  • What is the health of high conservation systems, environmental assets and progressing in achieving environmental and other public benefit outcomes?
  • Have these been identified and protected through statutory provisions?

AWR 2005 has assessed the current status of river and wetland health assessment frameworks and will be developing a nationwide assessment framework that builds upon existing state-based approaches

Objective (iv) complete the return of all currently overallocated or overused systems to environmentally-sustainable levels of extraction

  • What water resource information is relevant to the consideration of issues of overallocation and overuse?

Key deliverables for the baseline:

  • What are the flow requirements (e.g. quantity, quality, timing, rate) for the environmental assets and relevant ecosystem functions (consider how these requirements are determined in different jurisdictions)?
  • What are the flow requirements for productive base of the resource?
  • What are the current flows?
  • What is the available water?
  • What quantity of water is allocated in the system?
  • What quantity of water is used in the system?

Objective (vii) water accounting which is able to meet the information needs of different water systems in respect to planning, monitoring, trading, environmental management and on-farm management

  • What water resource information identified for the purposes of the baseline, including gaps, will inform the water accounting reforms and future water accounting processes?
  • The Baseline will utilise existing water measurement processes to report on the state of the water resource including:
    • water quantity
    • quality and use
    • identify gaps in knowledge about these measures.
  • Identification of knowledge gaps, and inconsistencies and incompatibilities in water data collection and management can inform the improvement of water accounting systems.
  • The application of standards for improved accounting and metering developed through the NWI Committee will help improve the quality of water resource assessments and therefore need to be considered for the repeatability of the assessment.
  • Knowledge gaps have been identified in a number of areas of the assessment. These include inconsistency in definition of sustainable yield (refer to Resource sustainability), lack of data covering key aspects of the water balance, and a lack of integration of data covering surface water resources, groundwater resources (refer to Surface water and groundwater interaction) and environmental conditions of catchments (refer to River and wetland health)
  • Current state and territory knowledge of water availability, entitlements, sustainable yield, diversions and extractions is presented in the section on water availability
  • Information on current flows (for the period 200405) and contextual data is provided for priority geographic areas in the Regional water resources assessments section

Objective VIII) policy settings which facilitate water use efficiency and innovation un rural and urban areas

  • How can we measure an increase in efficiency of Australia 's water use?

Key questions/deliverables for the Baseline

  • How do we measure the efficiency of water use?
  • What information will assist future comparisons of water resource use in agriculture?
  • How is water being used now in Australia ?
  • How much water is lost in water storage and delivery systems?
  • How much water do households use now?
  • How much water is recycled or reused?
  • Note: It is not the purpose of the BWRA to make determinations on most efficient methods of agricultural or other water use because of the reasons noted by the Productivity Commission. However through the use of a water balance analysis, issues relating to efficiency of water storage and distribution systems can be analysed.
  • Water use information has been compiled for AWR 2005 through the use of the ABS Water Account (refer to Water use ), data modelled for priority geographic areas, information compiled as part of the Level 2 water balances and agricultural water use information.

 

Objective X)

Recognition of the connectivity between surface and groundwater resources and connected systems managed as a single resource

  • What is the current knowledge of connectivity of surface and groundwater resources? Are they being managed as a single resource?
  • Connectivity of resources will not change through NWI reforms, but our understanding and management of them will.

Key questions/deliverables for the Baseline

  • To what extent are developed surface water resources connected to ground water resources? (consider how connectivity is measured in different jurisdictions)
  • To what extent are other water resources connected to each other?
  • To what extent are these connections currently understood?
  • How are these connections managed?

 

  • Assessment of the extent to which resources are managed in an integrated manner is shown in the surface water and groundwater interaction section.
  • Indication of systems where connectivity is understood and is taken into account when developing management arrangements for water systems (surface or groundwater) or through management as a single resource is shown in the water management section.
