Using empirical research, ICLEI is developing a framework and tools to assess changes in food-water-energy nexus, their related trade-offs and the building of innovative capabilities in cities for developing innovative solutions to the food, water and energy nexus and manage green and blue infrastructure at the urban level. ICLEI is supporting the development of frameworks and tools that guide urban governance on the food-water-energy nexus, delivering innovative solutions to mitigate climate change and biodiversity loss, while advancing development goals from food security to job creation across cities worldwide. The project assesses the changes in trade-offs of food-water-energy nexus (FWEN) in green and blue infrastructure (GBI) and their association with spatial planning and governance in eight cities using empirical cases. This will provide a better understanding of the barriers that hinder innovative and integrated FWEN approaches using GBI at different scales; and look for the common features of diverse interventions.
