• Water from the Neue Donau is fed into the Alte Donau.

• Safeguard the outstanding water quality of the Alte Donau in the long term through:

reduction of Phosphor

regulation of pH

• Start construction works: March 2016

• Operation begin: August 2016

Innovative lakebed biological filter in the Water Park


Measures: Lakebed biological filter


18February 2019

• New concept for management of underwater plants

increase the biodiversity of the underwater plants

planting of low growing macrophytes

equip mowing boats with GPS, sonar, hard- and software

digital mowing plan

• Positive effects in controlling increased plant growth during heat wave in 2018

• Concept transferred to the Flood Protection Channel “Neue Donau”

Climate Change Threats



23February 2019

Governance and information

Increased ecosystem resilience (revitalisation, initiation)

Raising awareness of climate change – ecosystems – biodiversity: events, climate platform, working with schools, idea and know-how transfer, adaption strategy of the City of Vienna, maintenance manual, feasibility studies

More biodiversity –more CO2-uptake, better microclimate

User steering & guidance, ecosystem-based technologies for event zones

More efficient maintenance and irrigation – less use of resources, less CO2 production

Sustainable sediment management, Retreats for fish during floods

More efficient sediment management – less use of resources, less CO2 production

• Ecosystem based adaption measures(maintenance and care)

Continuation

• Feasibility Study in another City for the ecosystem based adaption measures

• Guidance for EU-cities (how to, problems, tipps, etc.)

• Uptake of results / measures for the continuation of the Vienna Climate Protection Programme

Replication

Continuation and Replication



29February 2019

• EU-funded projects are the ultimate possibility for networking, internationalization and exchange of know how

• Do well and talk about it (Communicate)

• Funded projects should be placed higher up (Strategic bodies, Municipal Board) to get thecorresponding importance in the city government

• But: implementation is in good hands with expertsin the municipal departments

• Networking with other departments in the city is sometimes a back-breaking work (and needs personal resources)

• Changing acceptance within the project length: skepticism gives way to pride

Good to know:

What we have learned so far I


30February 2019

Always do:

• Advocacy of stakeholders very important

• Incorporate employees already in the application

phase

• Get everyone on board, convince colleagues

• Regularily inform your team

• If project changes occur, contact the EU before the

EU contacts you!

• Never underestimate the administrative effort and plan the effort in your personnel resource planning

• Do not promise anything in the application that can not be held
