Ecosystem services

  • those functions of ecosystems that directly or indirectly support human well-being

  • human well-being:

    • Security

    • Basic material for good life

    • Health

    • Good social relations

    • Freedom of choice and action


Ecosystem services

  • Supporting and regulating services

  • Provisioning services

  • Cultural services


Ecosystem services

  • Supporting services

    • Soil formation

    • Net primary production

    • Nutrient cycling

    • Water cycling

    • Pollination

    • ...


Ecosystem services

  • Regulating services

    • Climate regulation

    • Water regulation

    • Disease regulation

    • Pest regulation

    • Water purification, waste treatment

    • Natural hazard regulation

    • ...


Ecosystem services

  • Provisioning services

    • Food

    • Fresh water

    • Fiber, wood fuel

    • Biochemicals, natural medicines, pharmaceuticals

    • Genetic resources

    • ...


Ecosystem services

  • Cultural services

    • Spiritual and religious values

    • Aesthetic values

    • Social relations

    • Sense of place

    • Recreational values

    • ...


Ecosystem services

  • Trade-off relations between different services

  • Different scales

  • Monetary values (market methods, avoided cost, replacement cost, travel cost method, hedonic pricing, contingent valuation, etc.)


Ecosystem services management

  • Primarily for setting the objectives of management

  • Management for maintaining and enhancing ecosystem services

  • Helps to explain the effects of human policies and impacts on ecological functions and human well-being


Ecosystem services management

  • Weighting ecosystem services trade-offs require quantification:

    • Full ecological(-economic) models are the gold standard, but costly and time-consuming

    • Consider service changes (gradients) from the status quo under a finite set of management options – monetary or nonmonetary units (scales, ratings, ranking, etc.)

  • Intrinsic values, moral obligations can set limitations!

  • Nonlinearities, irreversibilities – precautionary value


  • Ecosystem services management

    When considering changes of several services

    • Value of service changes: V × ∆S

    • Uncertainties – using ranges

    • Other considerations (equity) – weighting services

    • Aggregation of different value changes OR discussion of disaggregated results


    Ecosystem services management –case study I.

    Central Arizona-Phoenix

    • Mesic and xeric landscape management


    Ecosystem services management –case study I.


    Ecosystem services management –case study II.

    Agricultural ecosystem: Kellogg Biological station in Michigan

    • Three agricultural management options compared with traditional practices


    Ecosystem services management –case study II.


    Ecosystem services management –case study III.

    Agricultural watershed in Iowa

    • Production scenario

    • Water quality improvement scenario

    • Biodiversity enhancement scenario


    Ecosystem services management –case study III.


    Ecosystem services management –case study III.


    Ecosystem services management –summary

    • Could be useful for considering ecosystems in their complexity at least to some extent

    • Helps defining management objectives through the quantifications of trade-offs

    • Requires knowledge of management options on service flows

    • Valuation of service changes is the most complicated, especially in monetary terms
