DPS 1: Szigetköz region-revitalization of ecological system [HU]

Location: Szigetköz floodplain, Hungary (largest island on the Danube)
Challenge: Danube diversion in 1992 significantly reduced water levels, impacting ecology and human uses.
Solution: Water replenishment systems built (1995-2022) to mimic natural Danube flow and restore water levels.
Key Stakeholders: Water management, disaster prevention, nature conservation, forestry, agriculture, local government, fishing, and tourism.
Benefits:
- Increased surface and groundwater levels.
- Improved water quality.
- Restored diverse aquatic habitats and fish populations.
- Healthy forest growth.
- Improved agricultural yields.
- Increased ecotourism opportunities.
- Enhanced flood protection.

Success Factors:
- Stakeholder collaboration in planning, construction, and operation.
- Prioritization of flood protection with ecological restoration goals.
- Dynamic control of water discharge based on natural fluctuations.
- Technical solutions like fish passages for ecological connectivity.
- Open planning processes and ongoing monitoring to adapt strategies.
Lessons Learned:
- Human interventions in water systems can have lasting ecological impacts.
- Restoration efforts can be successful in heavily modified water bodies.
- Stakeholder involvement and collaboration are crucial for long-term success.
- Ongoing monitoring allows for adjustments and ensures effectiveness.
