Managing Salinity with Markets, Plants and Engineering (How do we move policy forward?) David Pannell

2 Degree of threat varies
Salt scald Suitable for salt-tolerant plants Completely unaffected

3 Values at threat vary Agricultural land Infrastructure
Threatened species, wetlands Water

4 Responsiveness varies
Required intensity of management varies (but is generally high) Myth: increase water use of annuals National Land & Water Resource Audit

5 Cost of management varies
Perennials profitable in some areas Unprofitable at high scale in most Water efficient irrigation technologies available Pumping is expensive Myth: farmers can & will change land use sufficiently with existing options

6 Put it all together ... Small areas have high priotity
high threat high value higher responsiveness to management low cost Some have moderate priority Most have relatively low priority

7 Prioritising funds We cannot buy a comprehensive solution
Focus $ support tightly onto high priority areas (or in ways that get high leverage) Some catchments warrant few $ Investment framework Myth: Sharing the money around evenly is “fair”

8 ICM Integrated Catchment Management (Planning) Myth: ICM Fine
Many situations require local management e.g. many farm problems, country towns Management (Planning) Planning doesn’t get you adoption What is the incentive? Myth: ICM

9 Protecting an environmental asset
Lake Tarbilin Lake Toolibin Diversion drain Pumps

10

11 If not ICM then what? Identify assets to protect
Analyse best method to protect them May be local, catchment scale or in between Consider “living with” salinity Compare with other catchments Prioritise at level above catchment Concentrate funds to create incentive

12 “Living with salinity” options
Water resources: desalination Built infrastructure: repair (Merredin townsite)

13 Servicing the majority
Develop and promote technologies for salinity prevention (leverage)

14 Servicing the majority
Develop and promote methods for “living with” salinity

15 Which technologies? Need a wide diversity They need to be profitable
Existing suite inadequate Different methods suit different situations/different problems

16

17 Policy approaches Policy instruments to encourage change on private land market-based instruments (NAP) subsidies (NHT) extension, information (Landcare) regulation Direct works (e.g. on public land) Technology development & industry development

18

19 Recommendations 1 Adopt a framework to assess and target salinity investments Reverse the planning approach: asset based, not catchment based Prioritise at state or national scale, not only catchment scale Modify role of catchment planning groups

20 Recommendations 2 Allow time and resources for analysis of options. Provide technical support. Adopt targets which come from analysis, not from desires Include options for “living with salinity” in the analysis

21 Recommendations 3 De-emphasise policy instruments to achieve land-use change (including market-based instruments) Recognise direct govt action (fully funded works, purchase water) Change the nature of extension & communication Promote properly evaluated technologies

22 Recommendations 4 Allocate 10-15% of salinity budget to technology development and industry development Plants (CRC) Engineering (CSIRO) Keep an open mind and expect it to need to be changed
