The ecosystem services assessment allowed the identification of emergencies which are due to risk phenomena and hydrogeological instability, and supported the definition of nature-based solutions to improve the urban resilience of Rocinha favela, in Rio de Janeiro, through the growth of environmental performance. The adoption of an ecosystem-based approach in a territorial context that is characterized by the informality of the urban development is the challenge to define and localize greening strategic actions in an intrinsically fragile place, aiming to regulate the water cycle and, therefore, improve the urban micro-climate and the favela livability.
