The CRUNCH project investigates food, water and energy as one complex system, leading to increased knowledge and discoveries that cannot emerge when investigated separately in ‘silos’.

It will combine an integrated decision support system and visualisation models with expert knowledge in waste, food, material fl ows, water and energy management and urban planning, architecture and urban governance. CRUNCH aims for ground-breaking outcomes that are truly transdisciplinary, working closely with local stakeholders at every step of the project.

Results and outcomes

The Integrated Decision Support System (IDSS) focuses on integrating the food, water, and energy systems in cities. The system will provide policy makers with a clear quantitative overview (on a digital platform) of how their cities’ food, water, and energy systems operate and what kind of changes to one system affects another one. The IDSS relies heavily on machine learning models that are invisible to the user. This permits the user to simply play around with different innovations in their food, water, and energy systems in an intuitive manner without worrying about complex calculations. Despite its simplicity, the IDSS is still able to reflect highly local conditions.

The team in Uppsala, Sweden has created the IDSS tool, the initial version of which is already accessible online.
