Macro-Region scale
Economic, social , trade, health, education, peace and security
Building common objectives, norms and values - ”Energy union”
National scale
Policy cohesion to address multiple national objectives
E.g hydropower storage as a lever intermittent renewable energy
Basin/Catchment scale
Competition & tradeoffs between users: irrigation, hydropower, domestic water supply
Finding synergies and new win-win opportunities
Urban scale
Resource stocks and flows external and internal, business models for services
