Case Studies

• FWE system analysis and simulation for the City of Vienna.

• Background: The future demand for food, water and energy is important for sustainable urban development. Urban development and land use are closely related and influence each other. Therefore, it is important to address the close interlinking of the decision areas of food, water, energy and land use as a starting point for analyses, scenarios and dynamics across the board and also in connection with trade.

Goals & Objectives

• A 3D City-GML model for Vienna will be combined with regional ecosystem models such as biomass production and trade to analyze and visualize the impacts of land use change on food production, integration of renewable energies, adaptation to climate change and water quality/quantity. For the case study region for the City of Vienna, the following aspects are considered in particular:

  • Urban food production and impacts on green areas and land use in the city.

  • Urban population development and land use.

  • Urban climate resilience (e.g. reduction of heat islands etc.)

  • Urban data and modelling standards for sustainable urban development scenarios.

  • Energy efficiency and flexibility potentials in water supply and wastewater treatment.

Potential Outcomes/Progress

• Urban data and modelling system (3D-CityGML) that integrates various results of existing tools and services.

• Visualization toolbox to illustrate the FWE system structure.

• Scenario development and visualization of possible dynamics.

Planned Activities including workshop/conferences/publications

• FWE Nexus system analysis.

• Sustainable urban development and the role of the FWE Nexus.

• Local experts' concerns to the Case study Vienna.

• Development of a common vision of future scenarios for Vienna

• Application of the proposed tools and discussion of the results and usability of tools.

• Development of options for actions and measures to reach the future targets regarding climate mitigation and adaptation.
