There has been a growing interest in Nature-Based Solutions (NBS) in recent years. These solutions use natural processes to improve urban water management. This interest acts as a response to the last-century Positivist approach, which produced the modern city by developing hard technological systems for urban resource management. The International Union for the Conservation of Nature (IUCN) defines NBS as actions to protect, manage and restore natural ecosystems in a sustainable way.
