Land use and land cover change and climate effects on ecosystem services

Summary of Workshop 4


Ecosystem services es
Ecosystem Services [ES] ecosystem services

  • Not always easy to quantify:

    • Provisioning, Regulating, Cultural, Supporting

  • Quantification may depend on subtle differences in land use intensity or biophysical/biochemical properties within the same „land cover“ or „land use“ class.

  • Not all ES are easily quantifible, or easily compared with the same metrics, e.g. $$$

  • Quantification of many ES allows analyzing conflicts and optimization of land management


Es quantification
ES ecosystem servicesquantification

  • ES take an antropogenticviewpointonly

  • Not always easy toidentifythe relevant scale

  • Itisimportanttoknowthe „system“, not just the LC

  • Different metricsaredifficulttocompare

  • Whatis an ecosystem?

  • Services oftenhighestatedgesortransitionzones (forestedge, lakeborders, etc.)

  • Maybemoreusefulas a generalcommunicationframeworkthan a managementtool...


Lu or lc es
LU or LC ecosystem services ES

  • There are only vague links between LC and ES, as use intensity or environmental properties affect ES considerably

  • There is a better link between LU and ES, at least if „use intensity“ (disturbance) is quantified.


Disantangling land use climate effects
Disantangling Land use & climate effects ecosystem services

  • Usually not easy, requires careful selection of study sites. Often, both C and LU/LC change at same time. Their individual effects then cannot singled out from one study area.

  • Only the careful choice of study sites that show independent variation in land use/cover and climate allow for a partitioning of these two important effects.


Quantifying effects
Quantifying effects ecosystem services

  • Important to keep uncertainties in mind

  • Especially when working with old and new maps, there may be a considerable change in positional or thematic accuracy, which may influence the conclusions we draw from derivations of ES from changes in LC/LU

  • Ensembles of error propagation modelling/quantification is a useful approach to quantify the degree of error.
