Spain - Medina Del Campo

OVERVIEW OF DEMO AIM

To analyse and value the role of groundwater‐related ecosystem services as natural insurance for hazard mitigation in a context of increasing climatic variability and to propose viable business options for the public/private financing of management measures that increase the provision of groundwater‐related ecosystem services.

Medina del Campo Groundwater Body

Increasing irrigation and urban water use has caused the severe deterioration of the provision of ecosystem services in the área. Main threats idntified are lowering piezometric aquifer levels, diffuse agricultural pollution and elevated As content.

Nature Based Solutions

Artificial recharge of aquifers and the control of extractions. Other additional or alternative measures, such substituting groundwater use for Surface resources or payments for reducing extractions, will be proposed based on stakeholders consultation to and analysis of their Environmental/Ecosystem impacts.

Key Stakeholders

  1. Assessment of the impacts of artificial recharge activities on the MCGB.
  2. Assessment of the risk management strategies.
  3. Analysis of the ecosystem services provided by the aquifer and wetlands.
  4. Analysis of the ecosystems resilience to climate change and human‐induced changes.

Methods and data to be used

Methods: Bivariate and multivariate methods; cartographic methods (GIS); economic modeling; damage valuation;risk assessment; Benefit Transfer; Cost-Benefit Analysis.

Data: Piezometric levels; surface water levels; chemical analyses of surface and groundwater; isotopic analyses of surface and groundwater; geological data; economic data on water uses; hazard losses estimates; estimates of ecosystem services values; etc

INSURANCE VALUE OF ECOSYSTEMS

The analysis of the payments for groundwater‐linked ecosystem services will be based on a cost‐benefit analysis of the management scenarios proposed to recover the aquifer, including the assessment of the provision costs of ecosystem services and the valuation of their benefits and of the avoided damages, according to the methodologies set in the project.

The incorporation of uncertainties and risks will provide the insurance value of ecosystems and co‐benefits of the different management scenarios analysed.

Payments for changes in the insurance value of ecosystems and co‐benefits can be distributed between stakeholders based on the sharing of costs and benefits.

Combination of public and private financing options to be investigated: taxation, conservation/hábitat banking, private investments in nature based solutions and/or payments by ecosystem services by direct/indirect beneficiaries of the mitigation of risks, etc.
