The Baguio City Flood Early Warning System Flood Mitigation and Action Plan report introduces a city-wide assessment for the conceptual design and implementation of nature-based solutions (NbS) as a new paradigm for climate adaptation, where both flood mitigation benefits, and other co-benefits are analyzed through a structured approach and in close consultation with the LGU and ADB. The report contributes to the knowledge base supporting the current paradigm shift in urban planning practices taking place in Baguio, guided by an overall vision to make the city more liveable, more resilient, and more sustainable.
