Impact on ecosystem services
Figure 2: Ecosystem services analysis for Underwater relocation area "Medemrinne Ost": Indication of habitat surface and quality change, i.e. situation before versus after measure implementation.From the ES assessment it is concluded that this measure generates overall a slightly positive expected impact for several ES, mainly for:
- “biodiversity”
- Cultural services
- Some regulating services: Erosion and sedimentation regulation (by water bodies); Water quality regulation: transport of polutants and excess nutrients; Water quantity regulation: transportation
The expected impact for the two development targets (“Water quantity regulation: dissipation of tidal and river energy”, and “Water for navigation”) is neutral.
The expected impact for the different beneficiary groups is limited, with a slightly positive expected impact for indirect and future use and for local and region use.
Table 1: Ecosystem services analysis for Underwater relocation area "Medemrinne Ost": (1) expected impact on ES supply in the measure site and (2) expected impact on different beneficiaries as a consequence of the measure.The screening of ecosystem services (ESS) that were effected by the measure Medemrinne Ost showed no clear results. Some ESS will be influenced positively, but the targeted ESS will not be effected. This outcome made clear that the screening of the effects on the ESS is not applicable on every type of measure executed in the TIDE project
