Urban Nexus

Project // IN-SOURCE: INtegrated analysis and modelling for the management of sustainable urban FWE ReSOURCEs

This project aims to develop a shared urban data and modeling framework to help decision makers (such as governments, utilities, developers, investors) identify, quantify and visualize FWE systems and their interrelations for urban strategic planning and FWE infrastructure investments.

As cities across the globe confront rapid change, they face common metabolic challenges to provide Food, Water and Energy (FWE) supplies. IN-SOURCE is based on three case studies in Ludwigsburg (Germany), New York (US) and Vienna (Austria), and will examine scenarios for an integrated CO2-neutral and sustainable infrastructure as well as the scalability and transferability of prototype solutions to other cities.


Development and application of tools for case studies in order to quantitatively assess the predicted impact of changes in urban land use due to population, climate change, the energy transition and the challenges of providing a truly resilient infrastructure.


  • Using a bottom up approach to model urban system development, combining aggregated results with large scale (mainly regional, up to national) system models
  • Involving urban stakeholders throughout the process, including generating indicators and data, developing tools to model and visualize the impacts and contributing to shaping strategies
  • Considering urban challenges in very di­fferent case studies and thus improving the transferability of the local results to global urban areas

Expected results and impacts

  • CityGML Application Domain Extensions (ADE) will be made available as an open specification, allowing any interested institution to adopt it and develop data resources in a shared data model
  • Stakeholder involved as working consortia for collaborative planning of local FWE infrastructure projects
  • Creation of shared urban data and modeling framework with specialized tools for applications in food, energy and water interactions
  • Methodology and software tool set will be made available for use by further cities and regions

Nexus Principles // The Water, Energy and Food securiy Nexus Principles

The Water-Energy-Food security Nexus Principles guide towards the application, implementation and operationalisation of the Water-Energy-Food security Nexus (WEF Nexus) approach in different contexts. The Principles were developed by practicioners based on their experience and grounded in research.
