Ecosystem services

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 services1

Ecosystem services

  • Supporting and regulating services

  • Provisioning services

  • Cultural services


Ecosystem services2

Ecosystem services

  • Supporting services

    • Soil formation

    • Net primary production

    • Nutrient cycling

    • Water cycling

    • Pollination

    • ...


Ecosystem services3

Ecosystem services

  • Regulating services

    • Climate regulation

    • Water regulation

    • Disease regulation

    • Pest regulation

    • Water purification, waste treatment

    • Natural hazard regulation

    • ...


Ecosystem services4

Ecosystem services

  • Provisioning services

    • Food

    • Fresh water

    • Fiber, wood fuel

    • Biochemicals, natural medicines, pharmaceuticals

    • Genetic resources

    • ...


Ecosystem services5

Ecosystem services

  • Cultural services

    • Spiritual and religious values

    • Aesthetic values

    • Social relations

    • Sense of place

    • Recreational values

    • ...


Ecosystem services6

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

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 management1

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 management2

    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

    Ecosystem services management –case study I.

    Central Arizona-Phoenix

    • Mesic and xeric landscape management


    Ecosystem services management case study i1

    Ecosystem services management –case study I.


    Ecosystem services management case study ii

    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 ii1

    Ecosystem services management –case study II.


    Ecosystem services management case study iii

    Ecosystem services management –case study III.

    Agricultural watershed in Iowa

    • Production scenario

    • Water quality improvement scenario

    • Biodiversity enhancement scenario


    Ecosystem services management case study iii1

    Ecosystem services management –case study III.


    Ecosystem services management case study iii2

    Ecosystem services management –case study III.


    Ecosystem services management summary

    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
