SUNEX provides an integrated modelling framework of advanced tools to model and assess the Food-Water-Energy (FWE) systems’ demand and supply sides, capture their interdependencies and maximize synergies through a nexus view that endorses efficient solutions for energy, water and food supply for urban regions.

The approach will be applied in four case study cities refl ecting diff erent socio-economic and climate characteristics, different consumption patterns and diff erent local and remote FWE resource shares. A monitoring and control sensor network will be tested to improve water and energy savings for local food production. The results will feed into FWE-supply guidelines ensuring replication to support the transition towards higher urban resilience.

Results and outcomes

SUNEX-IMFA is an integrated modelling framework focused on constructing alternative development pathways and their impacts on supply and demand for food-water-energy and their key nexus-effects. The first pathway is a ‘business as usual’ scenario that describes a continuation of historical trends, including recently enacted food-water-energy policy trends without additional measures on sustainable development. The second pathway is a ‘sustainable development scenario,’ where modelling is done to reflect an active transition towards efficient, sustainable and low-carbon food-water-energy systems. Both scenarios are developed following consistent assumptions on expected future socio-economic and technological developments of the pilot cities considered.

SUNEX policy guidelines

The analysis aims to better understand the interactions between selected policy areas, to identify trade-offs and co-benefits and to prioritize policy and associated action to support the optimization of food-water and energy nexus in a context of climate change mitigation and post-covid recovery actions.
