  1. THE ECOSYSTEM SERVICES PROJECT Dr Wendy Proctor Policy and Economic Research Unit CSIRO Land and Water

  2. DEFINITION “…the conditions and processes through which natural ecosystems, and the species that make them up, sustain and fulfill human life” Daily (1997)

  3. OBJECTIVES • Document ecosystem services in a range of Australian ecosystems • Assess consumption and value, benefits and beneficiaries, threats and opportunities • Dialogue and involvement with decision makers at all levels

  4. FRAMEWORK

  5. KEY ISSUES • Integrating management across ecosystem services by: re-establishment of the Lower-Goulburn River floodplain; alternative revegetation strategies; and nutrient management including the merits of alternative approaches. • Managing land-use intensification. • Managing transitions in land-use. • Managing vegetation for the full suite of ecosystem services. • Managing cultural, heritage and option values. • Maintaining soil health. • Accounting for the value of non-agricultural land and water-uses. • Water and salinity management. • Anticipating and adaptively managing emerging issues.

  6. SCENARIOS APPROACH

  7. ECOSYSTEM SERVICES FROM DAIRY • Output • Dynamic model of milk producing area on a dairy farm with emphasis on ecosystem services • Results • Greatest variation between dairy management practises is in feed supplementation and water use efficiency • Water re-use systems on high input farms increase milk production and reduce nutrient runoff • Higher herd productivity through the provision of shade and shelter

  8. ECOSYSTEM SERVICES ON THE FLOODPLAIN • Output • Spatially explicit dynamic model for generation and evaluation of future management options • Results • Floodplain is highly interconnected system – model shows complexity, key drivers and trade-offs • Improved management of river flows has implications for a suite of other services • Extremely long time scales are involved in the vegetation change (Hab. Ha. Score) and therefore management process

  9. ECOSYSTEM SERVICES FROM VEGETATION PATTERNS • Outputs • A GIS model that shows changes in various ES’s as vegetation cover changes • Results • Benefits of shelter belts peaks at 40% native veg cover • Erosion rates much lower under native veg • Water yield to channel is affected by spatial configuration of veg • Water yield to deep drainage is sensitive to the area of deep rooted perennials

  10. ECOSYSTEM SERVICES AND ECONOMY AT CATCHMENT SCALE • Outputs • Input output model that tracks dollars, water and nutrients among 33 sectors of the GB economy • Results • Dairy processing industry has largest influence on economy • ‘Other horticulture’ has largest influence on water use for each dollar invested in industry • Simultaneous evaluation of investments in regulation of river flows, stream health etc. and importance of industries

  11. TOURISM IN THE UPPER CATCHMENT • Significant source of income for the upper Goulburn Broken Catchment

  12. MANAGEMENT PRACTICES • On Site Management • Riparian Zone Management • Demand Management • Education

  13. SCENARIO WORKSHOP • Main recreation and tourism activities in catchment • What ecosystem services do these depend on? • Issues and relationships • Main drivers • Options

  14. ASSESSMENT • Deliberative Multi-criteria Evaluation • Multi-criteria Decision Analysis • Simplify • Identify trade-offs • Structure/transparency • Options • Criteria • Sensitivity analysis • Heuristic approach • Citizen’s Jury • 10 to 20 participants • Specific charge • Facilitated • Time to deliberate • Witnesses engaged • Consensus often reached • Combined Approach • Facilitation, interaction, consensus • Structure, integration

  15. OPTIONS • Business As Usual • Maximise Ecosystem Services Concerns • Minimise Ecosystem Services Concerns /Maximise Social Concerns • Minimise Ecosystem Services Concerns/Maximise Economic Concerns • The Sustainable Tourism/Environment/Society Mix

  16. Objectives • To protect and enhance the environment and natural attributes of the catchment that attract recreational users. • To balance recreational development and use of our catchment (particularly in riparian zones) with the environmental and economic values of the community.

  17. OBJECTIVES • To protect and enhance the environment and natural attributes of the waterways that attract recreational users. • To encourage appropriate and sustainable recreational development and use of the waterways in keeping with demand.

  18. CRITERIA • Ecosystem Services • Water Quality • Water Quantity • Biodiversity/Native Biota • Sediment Filtration/Erosion control • Nutrient Management/waste assimilation • Shading • Stream Health (instream and riparian zones) • Aesthetics/scenic views Social/Cultural Public Access Jobs Economic Costs Benefits

  19. FINAL STEPS • Sensitivity Analysis • uncertainty of impact data and weights • test sensitivity of outcomes for most crucial and contentious criteria and impacts. • Reiterations

  20. The Charge • To agree on a set of weights for criteria deemed important in deciding between options for recreation and tourism in the upper GB Catchment

  23. Final ranking of options

  24. FINDINGS • Importance of Ecosystem Services in recreation and tourism management • Need for greater research on public access issues • Need for research on effects of education on tourists with respect to environmental damage • Need to investigate methods for the recovery of management costs • Research the role of market and other incentives in limiting environmental damage of tourists

  25. CATCHMENT COMMUNICATION • ESs a central theme in catchment strategies in five states • Agencies use the term in communications with landholders

  26. RESEARCH NETWORK • Network connects researchers in Aus, NZ, Us, Germany, Switzerland and South Africa • Katoomba Group • ES initiatives in other CSIRO Divisions

  27. GENERAL COMMUNICATIONS • Almost 1500 copies of inventory report distributed • Web hits 1000/month • Newsletter, 2 journal papers, 10 conference papers, 2 books…

  28. Next • Markets for Ecosystem Services • To combat: • Irrigation induced salinity • Dryland salinity
